     This Registration Statement covers the registration of (i) $115 million of
Common Stock offered by the Registrant pursuant to an underwritten public
offering, which includes $15 million of Common Stock issuable upon exercise of
the Underwriters' over-allotment option (the "Public Offering"), and (ii) $5
million of Common Stock offered to Cisco Systems, Inc. at the offering price,
net of the underwriting discount, by the Registrant in a concurrent offering
that is not underwritten (the "Cisco Offering"). Therefore, this Registration
Statement contains two forms of prospectus: one to be used in connection with
the Public Offering (the "Public Offering Prospectus") and the other to be used
in connection with the concurrent Cisco Offering (the "Cisco Prospectus"). The
Public Offering Prospectus and the Cisco Prospectus are identical in all
respects except for the front cover pages, the tables of contents, the
descriptions of the plan of distribution and the descriptions of legal matters.
The alternate pages of the Cisco Prospectus are included herein after the final
page of the Public Offering Prospectus and are labeled "Alternate Page for Cisco
Prospectus." Final forms of each prospectus will be filed with the Securities
and Exchange Commission under Rule 424(b).

                               PROSPECTUS SUMMARY
 
HIGH SPEED ACCESS CORP.
 
     We are a leading provider of high speed Internet access via cable modem to
residential and commercial end users in exurban areas. We believe that we
provide the most comprehensive turnkey solution available to the cable operator
in exurban markets. Our service enables subscribers to receive Internet access
at speeds substantially faster than traditional Internet access at minimal cost
to the cable operator. We enter into long term exclusive contracts with cable
operators to provide them with our service. In exchange for providing us access
to their customers, we pay our cable partners a portion of the monthly fees we
receive from the end users.
 
     We target exurban markets, defined as cable systems with fewer than 100,000
homes passed. This market encompasses approximately 48 million homes, or
approximately one-half of the homes passed by cable in the United States. We
have exclusive agreements to provide our services to 11 cable operators,
covering 43 systems and approximately 868,000 homes passed. We also have
exclusive letters of intent to provide these services to another 23 operators
representing an additional 30 systems and approximately 230,000 homes passed. We
have commenced full operations in 14 systems covering approximately 210,000
homes marketed, initiated operations in 16 systems covering an additional
276,000 homes, and have approximately 2,800 cable modem end users.
 
     Vulcan Ventures, Incorporated, an affiliate of Microsoft co-founder Paul
Allen, beneficially owns 54.2% of our common stock before the offering. Vulcan
also owns Charter Communications, Inc., the seventh largest cable system
operator in the United States. Charter has agreed to provide us with exclusive
access to at least 750,000 homes passed, and Vulcan has an equity incentive to
cause Charter to provide us up to an additional 5 million homes passed.
 
     We seek to provide our services to the rapidly expanding number of
households and businesses in the United States that are online. According to
industry analysts, there were 26.5 million households with Internet access in
the United States in 1998. Industry analysts expect this number to grow to
nearly 58.4 million households by the end of 2002. One recent industry report
estimated that, by the end of 2002, 15.8 million U.S. households will have
broadband Internet connections. We believe that cable modems will become the
leading method of broadband Internet access for residential end users. Because
cable modems can operate at peak transmission speeds of up to 10 megabits per
second (Mbps), compared with 56 kilobits per second (Kbps) for standard
telephone modems, cable modem users will be better able to use increasingly
complex entertainment and commercial service offerings that integrate voice,
video and data on the Internet. In addition, a cable modem provides the
potential for an always-on connection to the Internet, eliminating the
inconvenience associated with the timing out of a telephone modem connection and
generally avoiding the need for dial-up procedures. We believe that many
businesses located in our target markets also will find our scalable,
cable-based Internet access to be the most cost-effective solution for their
Internet needs because of the limited availability and high cost of obtaining
competing high speed telephone circuitry in many exurban markets.
 
BENEFITS TO THE CABLE OPERATOR
 
     To take advantage of the increased usage of the Internet, many cable
operators are seeking a rapid and cost-effective means of providing high speed
Internet access to their customers. We have developed a comprehensive solution
that provides the following benefits:
 
     - Full turnkey solution requiring minimal effort by the cable operator;
 
     - Rapid implementation of high speed access in either upgraded or
       non-upgraded systems;
 
     - Source of additional revenues with minimal associated operating or
       capital cost; and
 
     - Dedicated onsite local and national end user marketing provided by us.
 
                                        1
<PAGE>   8
 
     Our exclusive focus on high speed Internet access enables the cable
operator, who may otherwise lack the necessary experience and resources, to
provide broadband Internet access quickly and cost effectively. We have
developed a standardized implementation and engineering process based on our
experience in the 30 systems we have installed to date, of which 14 are in full
operation. As a result, we generally are able to commence full operations in a
system within 90 days after we have entered into a contract with our cable
partner.
 
STRATEGY
 
     Our strategy has the following key elements:
 
     - Focus on the exurban market where there is less competition and cable
       operators have a greater need for our turnkey services;
 
     - Rapidly expand our base of cable partners;
 
     - Offer a full turnkey value proposition to the cable operator and create
       long term partnerships;
 
     - Provide a range of products and services to residential and commercial
       end users;
 
     - Increase end user penetration through dedicated marketing and local
       content;
 
     - Leverage economies of scale inherent in our business;
 
     - Leverage the media and cable industry experience of our investors,
       directors and management; and
 
     - Selectively explore international expansion and domestic acquisition
       opportunities.
 
HISTORY AND SPONSORSHIP
 
     In April 1998, Broadband Solutions, one of our founding investors,
sponsored our acquisition of High Speed Access Network, Inc. of Denver, Colorado
and CATV.net, Inc. of Louisville, Kentucky. In November 1998, Vulcan Ventures
invested $20 million in our company. Vulcan has advised us that it intends to
exercise its right to purchase 5 million shares of our Series C convertible
preferred stock for $5.00 per share, which will be converted into 5 million
shares of our common stock upon completion of the offering. Vulcan's subsidiary,
Charter Communications, has entered into an agreement giving us exclusive access
to at least 750,000 homes passed in its exurban markets. Vulcan also has
warrants to purchase up to an additional 5 million shares of our common stock,
for $5.00 per share, which become exercisable at the rate of one share per home
passed committed to us by Charter in excess of 750,000. Vulcan has substantial
investments in media, Internet and new media companies, including USA Networks,
ZDTV, Beyond.com, N2K, Inc., Wink Communications, Value America, Inc. and
Priceline.com. Certain of the principals of Broadband Solutions, which
beneficially owns 36.8% of our common stock before the offering, co-founded and
invested in Premier Parks Inc., Regal Cinemas, Inc. and Regent Communications,
Inc. The investor group that founded High Speed Access Network, Inc. includes
cable television pioneer Joseph Gans, III. Concurrently with this offering,
Cisco Systems, Inc., one of our major equipment suppliers, has agreed to
purchase $5 million of our common stock at the initial public offering price,
net of the underwriting discount. We believe that our sponsor group and their

     In addition to the           shares of common stock to be outstanding after
the offering, we may issue a total of 2,841,500 shares of common stock pursuant
to our stock option plans, as follows:
 
     - Under our 1998 stock option plan, we have granted options to purchase
       541,500 shares at a weighted average exercise price of $2.59 per share,
       all of which will become exercisable upon completion of the offering. No
       more options will be granted under our 1998 stock option plan.
 
     - Under our 1999 stock option plan, we have reserved 2 million shares for
       issuance. We have granted options to purchase 30,000 of these shares at
       an exercise price of $5.00 per share, and 31,000 of these shares at an
       exercise price equal to the initial public offering price per share. None
       of the options granted under the 1999 stock option plan is currently
       exercisable.
 
     - Under our 1999 non-employee director stock option plan, we have reserved
       300,000 shares for issuance. We have granted options to purchase 122,500
       shares at an exercise price of $5.00 per share, all of which are
       currently exercisable.
 
     Additionally, we have granted Vulcan Ventures warrants to purchase up to 5
million shares of our common stock at an exercise price of $5.00 per share.
These warrants became exercisable at the rate of one share per home passed
committed to us by Charter in excess of 750,000. Approximately 15,000 of these
warrants are currently exercisable. See "Certain Transactions."
 
     In addition, upon closing of the offering, we will issue approximately
            shares of common stock in payment of accrued dividends on our
convertible preferred stock, all of which will convert by their terms into
shares of common stock.

                                  RISK FACTORS
 
     You should carefully consider the following factors and other information
in this prospectus before deciding to invest in our common stock. The risks and
uncertainties described below are not the only ones facing our company.
Additional risks and uncertainties (including risks and uncertainties not
presently known to or considered material by us) may also impair our business.
If any of the following risks actually occur, our business and financial results
could be materially and adversely affected. In that case, the trading price of
our common stock could decline and you could lose all or part of your
investment.
 
WE HAVE A LIMITED OPERATING HISTORY.
 
     We have a limited operating history upon which you can evaluate our
business. We began offering our services to cable operators in October 1997. As
an early stage company in the new and rapidly evolving market for high speed
Internet access services, we face numerous risks and uncertainties. Some of
these risks relate to our ability to:
 
     - Deploy our services cost effectively in the systems we have under
       contract;
 
     - Enter into additional agreements with cable operators to expand our
       services to new markets;
 
     - Attract and retain sufficient end users to achieve profitable operations;
 
     - Attract, retain and motivate qualified personnel;
 
     - Respond to actions taken by our competitors; and
 
     - Upgrade and enhance our technologies and expand our product and service
       offerings.
 
     Our financial success will depend on the commercial acceptance and
profitability of our services. If we are unsuccessful in addressing these risks
or in executing our business strategy, our business and financial results will
suffer. If we encounter significant problems with our billing and collections
process, our business and financial results could be materially and adversely
affected.
 
WE HAVE A HISTORY OF LOSSES AND EXPECT FUTURE LOSSES.
 
     Since our founding, we have not been profitable. We have incurred
substantial costs to create and introduce our broadband Internet access
services, to operate these services, and to grow our business. We incurred
operating losses of approximately $10 million from April 3, 1998 (Inception)
through December 31, 1998. Our limited operating history and our ambitious
growth plans make predicting our operating results, including operating
expenses, difficult.
 
     We expect to incur substantial losses and experience substantial negative
cash flows from operations for at least the next several years as we expand our
business. The principal costs of expanding our business will include:
 
     - Substantial direct and indirect selling, marketing and promotional costs;
 
     - System operational expenses, including the lease of our Internet
       backbone, which has a traffic capacity in excess of our current needs;
 
     - Costs incurred in connection with higher staffing levels to meet our
       growth;
 
     - The acquisition and installation of the equipment and software necessary
       to enable our cable partners to offer our services; and
 
     - Costs in connection with acquisitions, divestitures, business alliances
       or changing technologies.
 
     If any of these costs or expenses is not accompanied by an increase in
revenues, then our business and financial results could be materially and
adversely affected.

<PAGE>   14
 
OUR BUSINESS MODEL IS UNPROVEN.
 
     Our success depends on continued growth in the use of the Internet and high
speed access services. Although Internet usage and popularity have grown
rapidly, we cannot be certain that this growth will continue in its present
form, or at all. Critical issues concerning the increased use of the
Internet--including security, reliability, cost, ease of access and quality of
service--remain unresolved and are likely to affect the development of the
market for our services. Relatively few companies currently offer cable-based
Internet access, and we do not believe any of those has been profitable.
Moreover, many industry analysts believe that Internet access providers will
become increasingly reliant upon revenues from content due to competitive
pressures to provide low cost or even free Internet access.
 
     The success of our business ultimately will depend upon the acceptance of
our services by end users, who will purchase or rent a cable modem from us and
pay both installation fees and monthly access charges for our services. We have
launched full operations in only 14 cable systems and we have approximately
2,800 cable modem end users. Additionally, although our primary service offering
is high bandwidth Internet access, we currently derive a substantial portion of
our revenues from standard dial-up Internet access, which we offer as a feeder
for our high speed offerings. We cannot predict whether demand for our high
speed Internet access services will develop, particularly at the volume or
prices we need to become profitable.
 
OUR ABILITY TO ATTRACT AND RETAIN END USERS DEPENDS ON MANY FACTORS WE CANNOT
CONTROL.
 
     Our ability to increase the number of our end users, and our ability to
retain end users, will depend on a number of factors, many of which are beyond
our control. These factors include:
 
     - Our ability to enter into and retain agreements with cable operators;
 
     - The speed at which we are able to deploy our services, particularly if we
       cannot obtain on a timely basis the telecommunications circuitry
       necessary to connect our cable headend equipment to our Internet
       backbone;
 
     - Our success in marketing our service to new and existing end users;
 
     - Competition, including new entrants advertising free or lower priced
       Internet access and/or alternative access technologies;
 
     - Whether our cable partners maintain their cable systems or upgrade their
       systems from one-way to two-way service;
 
     - The quality of the customer and technical support we provide; and
 
     - The quality of the content we offer.
 
     In addition, our service is currently priced at a premium to many other
online services and many end users may not be willing to pay a premium for our
service. Because of these factors, our actual revenues or the rate at which we
will add new end users may differ from past increases, the forecasts of industry
analysts, or a level that meets the expectations of investors.
 
OUR QUARTERLY OPERATING RESULTS ARE LIKELY TO FLUCTUATE SIGNIFICANTLY
 
     Our revenues and expenses, and in particular our quarterly revenues,
expenses and operating results have varied in the past and may fluctuate
significantly in the future due to a variety of factors, many of which are
outside of our control. These factors include:
 
     - The rate at which we enter into contracts with cable operators for
       additional systems;
 
     - The rate at which end users subscribe to our services;
 
     - Changes in revenue splits with our cable partners;
 
     - The pace of the rollout of our service to our cable partners;
                                        8
<PAGE>   15
 
     - Price competition in the Internet and cable industries;
 
     - Capital expenditures and costs related to infrastructure expansion;
 
     - The rate at which our cable partners convert their systems from one-way
       to two-way systems;
 
     - End user turnover rates;
 
     - Our ability to protect our systems from telecommunications failures,
       power loss and software-related system failures;
 
     - Changes in our operating expenses including, in particular, personnel
       expenses;
 
     - The introduction of new products or services by us or our competitors;
 
     - Our ability to enter into strategic alliances with content providers; and
 
     - Economic conditions specific to the Internet and cable industries, as
       well as general economic and market conditions.
 
     In addition, our operating expenses are based on our expectations of the
future demand for our services and are relatively fixed in the short term. We
may be unable to adjust spending quickly enough to offset any unexpected demand
shortfall. A shortfall in revenues in relation to our expenses could have a
material and adverse effect on our business and financial results.
 
     You should not rely on quarter-to-quarter comparisons of our results of
operations as an indication of future performance. It is possible that in some
future periods our results of operations may be below the expectations of public
market analysts and investors. In that event, the price of our common stock is
likely to fall.
 
WE NEED TO AGGRESSIVELY PURSUE AND COMPLETE ACCEPTABLE RELATIONSHIPS WITH CABLE
OPERATORS.
 
     Our success depends, in part, on our ability to gain access to cable
customers. We gain that access through agreements with our cable partners. There
can be no assurance that we will be able to establish or maintain relationships
with cable operators. Even if we are able to establish and maintain those
relationships, there can be no assurance that we will be able to do so on terms
favorable to us or in the quantities we need to become profitable. In addition,
our failure to form partnerships with a large number of cable operators as
quickly as possible permits other cable-based broadband service providers to
enter into exclusive agreements and effectively exclude us from the systems
covered by those agreements. Furthermore, in order to rapidly deploy our
services within a market, we typically begin installation of our equipment and
related telecommunications circuits in the cable system prior to the execution
of final documentation. If we are unable to finalize our contractual
relationship with a cable operator, if the exclusive relationship between us and
our cable partners, or between our cable partners and their cable customers, is
impaired, or if we do not become affiliated with a sufficient number of cable
operators, our business and financial results could be materially and adversely
affected.
 
OUR LARGEST CABLE PARTNER CAN TERMINATE ITS CONTRACT WITH US.
 
     Our largest cable partner is Charter Communications. Charter has committed
to provide us exclusive access to at least 750,000 homes passed. Vulcan
Ventures, Charter's owner, has equity incentives to cause Charter to provide us
additional homes passed, although neither Vulcan nor Charter is obligated to do
so. Under our network services agreement, Charter can terminate our exclusivity
rights, on a system-by-system basis, if we fail to meet performance benchmarks
or otherwise breach our agreement, including our commitment to provide content
designated by Vulcan. Moreover, Charter can terminate our agreement, for any
reason, as long as it purchases the associated cable headend equipment and
modems at book value and pays us a termination fee based on the net present
value of the revenues we otherwise would earn for the remaining term of the
agreement from those end users subscribing to our services as of the date of
termination. There can be no assurances we will meet our performance benchmarks
or that Charter will not decide to terminate our agreement for any other reason.
If Charter were to terminate this agreement,
                                        9
<PAGE>   16
 
in whole or for any material system, our business and financial results would be
materially and adversely affected.
 
OUR AGREEMENTS WITH VULCAN VENTURES COULD CONSTRAIN OUR ABILITY TO GENERATE
REVENUES FROM PROVIDING CONTENT AND FUTURE SERVICES OUR END USERS MAY DEMAND.
 
     Under our programming content agreement with Vulcan Ventures, Vulcan has
the right to require us to carry, on an exclusive basis in all cable systems we
serve, content it designates. Vulcan content may include start-up and related
web pages, electronic programming guides, other multimedia information and
telephony services. We will not share in any revenues Vulcan may earn through
the content or telephony services it provides. We must provide all equipment
necessary for the delivery of Vulcan content, although Vulcan will reimburse us
for any costs we incur in excess of $3,000 per cable headend. Vulcan cannot
charge us for any Vulcan content through November 25, 2008; after that date we
will be obligated to pay Vulcan for this content at the lowest fee charged to
any Internet service provider who subscribes to Vulcan content.
 
     Vulcan has the right to prohibit us from providing content or telephony
services that compete with Vulcan content and can require us to remove our
competing content. Moreover, many industry analysts believe that Internet access
will become increasingly reliant upon revenues from content due to competitive
pressures to provide low cost or even free Internet access. If Vulcan were to
require us to remove our content or substitute its telephony services for any we
might provide, we could lose a source of additional revenues and might not
recover all related costs of providing our content or telephony services.
Vulcan's ability to prohibit us from providing content and telephony services
means that Vulcan's interests are not necessarily aligned with those of our
other stockholders.
 
BECAUSE OF OUR RELATIONSHIP WITH VULCAN VENTURES, NEW INVESTORS WILL HAVE LITTLE
INFLUENCE OVER MANAGEMENT DECISIONS.
 
     Vulcan has advised us that, on or before the date we complete this
offering, it intends to purchase 5 million shares of our Series C convertible
preferred stock at a price of $5.00 per share under an agreement entered into in
November 1998. Upon completion of the offering, the Series C convertible
preferred stock automatically will convert into 5 million shares of common
stock. As a result of its purchase of our Series C preferred stock, Vulcan will
beneficially own approximately      % of our outstanding common stock following
the completion of the offering (     % if the underwriters exercise the entire
over-allotment option). Vulcan also has warrants to purchase up to an additional
5 million shares of our common stock, which become exercisable at the rate of
one share per home passed committed to us by its subsidiary, Charter
Communications, in excess of 750,000. Accordingly, Vulcan will be able to
significantly influence and possibly exercise control over most matters
requiring approval by our stockholders, including the election of directors and
approval of significant corporate transactions. This concentration of ownership
may also have the effect of delaying or preventing a change in control. In
addition, conflicts of interest may arise as a consequence of Vulcan's control
relationship with us, including (a) conflicts between Vulcan and its other
affiliates, as a stockholder with effective control and our other stockholders,
whose interests may differ with respect to, among other things, our strategic
direction or significant corporate transactions, (b) conflicts arising in
respect of corporate opportunities that could be pursued by us, on the one hand,
or by Vulcan, on the other hand, or (c) conflicts arising in respect of any new
contractual relationship between us, on the one hand, and Vulcan, on the other
hand. In particular, Vulcan is the owner of Charter, our largest cable partner.
Additionally, Vulcan has the exclusive right to provide the first page our end
users see when they log on to our service and, if it provides that first page,
will be entitled to all of the related revenues. Moreover, Vulcan can prohibit
us from providing content that competes with content it chooses to provide, and
can prohibit us from providing telephony services if it chooses to provide those
services. See "Certain Transactions."

INVESTORS MAY SUFFER SUBSTANTIAL DILUTION FROM OTHER TRANSACTIONS.
 
     As an inducement to Vulcan to cause Charter Communications to commit
additional systems to us, we have granted Vulcan warrants to purchase up to 5
million shares of our common stock at an exercise price of $5.00 per share.
These warrants become exercisable at the rate of one share for each home passed
committed to us by Charter in excess of 750,000. To the extent that Vulcan
becomes eligible to exercise all or a significant portion of these warrants, our
stockholders will experience substantial dilution. In the future, we also may
issue additional stock or warrants to purchase our common stock in connection
with our efforts to expand the distribution of our services. Stockholders could
face additional dilution from these possible future transactions.
 
DARWIN, OUR FORMER DIGITAL SUBSCRIBER LINE TECHNOLOGY DIVISION, AND OUR
PRINCIPAL STOCKHOLDERS ARE NOT RESTRICTED FROM PROVIDING COMPETING HIGH SPEED
INTERNET ACCESS SERVICES.
 
     Before completion of the offering, we plan to transfer all of the assets
used in our digital subscriber line technology division to Darwin Networks,
Inc., a newly-formed subsidiary. We plan to distribute all of the Darwin common
stock to our current stockholders before completion of the offering. Darwin's
digital subscriber line technology is an alternative method of providing high
speed Internet access to end users using the telephone infrastructure. Although
Darwin is at an early stage of its development and is not presently targeting
exurban markets, if Darwin were to deploy this technology successfully in the
future in partnership with wireline telephone providers in markets where we
provide our high speed Internet access, Darwin could become one of our
competitors. Furthermore, as a result of the distribution of the Darwin common
stock to our current stockholders, with the exception of the warrant we will
receive from Darwin, the benefits of providing this service will no longer
accrue to our stockholders. Neither Darwin nor our principal stockholders,
Vulcan Ventures and Broadband Solutions, will be restricted from providing
competing high speed digital subscriber line Internet access. If Darwin is
successful, our current stockholders and not those purchasing in the offering
will benefit. See "Certain Transactions."
 
ONE-WAY CABLE SYSTEMS INCREASE OUR OPERATING COSTS AND MAY NOT PROVIDE THE
QUALITY NECESSARY TO ATTRACT CUSTOMERS.
 
     Although our service can operate in one-way cable systems, where data can
be transmitted at high speeds from the cable headend to the end user, the end
user in a one-way system can only transmit data back to through the cable
headend via a standard telephone line. Because we must support the telephone
return component of the system, we incur higher operating costs in one-way
systems. Consequently, if our cable partners do not upgrade to two-way
capability at the rate we anticipate, our financial results will be negatively
affected. Additionally, one-way high speed cable services may not provide the
quality of experience and variety of applications necessary to attract and
retain end users.
 
OUR CABLE PARTNERS COULD SELL THEIR SYSTEMS OR BE ACQUIRED.
 
     In recent years, the cable television industry has undergone substantial
consolidation. If one of our cable partners is acquired by a cable operator that
already has a relationship with one of our competitors or that does not enter
into a contract with us, we could lose the ability to offer our cable modem
access services in the systems formerly served by our cable partner, which could
have a material and adverse effect on our business and financial results. Many
of the cable operators with whom we have contracts operate multiple systems,
thus increasing the risk to us if they are acquired. Moreover, it is common in
the cable industry for operators to swap systems, which could cause us to lose
our contract for a swapped system. Even though many of our contracts obligate
our cable partners to pay us a termination fee if they sell their system to
another operator who does not assume our contract, the termination fee may not
be adequate to ensure that the successor operator assumes our contract, or to
compensate us fully for the loss of future business in that system.
 
                                       11
<PAGE>   18
 
OUR CABLE PARTNERS COULD LOSE THEIR FRANCHISES.
 
     Cable television companies operate under franchises granted by local or
state authorities that are subject to renewal and renegotiation from time to
time. A franchise is generally granted for a fixed term ranging from five to 15
years, although in many cases the franchise is terminable if the franchisee
fails to comply with the material provisions of its franchise agreement. No
assurance can be given that the cable operators that have contracts with us will
be able to retain or renew their franchises. The non-renewal or termination of
any of these franchises would result in the termination of our contract with the
applicable cable operator.
 
EFFECTIVELY MANAGING OUR GROWTH MAY BE DIFFICULT.
 
     To manage our anticipated growth, we must continue to implement and improve
our operational, financial and management information systems; hire, train and
retain additional qualified personnel; continue to expand and upgrade core
technologies; and effectively manage our relationships with our end users,
suppliers and other third parties. Our expansion could place a significant
strain on our services and support operations, sales and administrative
personnel, and other resources. In fact, our predecessor companies had
inadequate accounting controls and procedures in place. While we believe that we
generally have adequate controls and procedures in place for our current
operations, our billing software is not adequate to meet our growth plans. We
are in the process of replacing our billing software with an integrated billing
and customer care software system that we believe is capable of meeting our
planned future needs. We could also experience difficulties meeting demand for
our products and services. Additionally, if we are unable to provide training
and support for our products, the implementation process will be longer and
customer satisfaction may be lower. There can be no assurance that our systems,
procedures or controls will be adequate to support our operations or that our
management will be capable of exploiting fully the market for our products and
services. The failure to manage our growth effectively could have a material
adverse effect on our business and financial results.
 
THE MARKET FOR INTERNET SERVICES IS HIGHLY COMPETITIVE.
 
     We face competition in two primary areas: (i) competition for partnerships
with cable operators from other cable modem-based providers of Internet access
services and (ii) competition for end users from providers of other types of
data and Internet services.
 
     We believe the major competitive factors in the market for partnerships
with cable operators include breadth of service, speed and ease of deployment,
revenue sharing arrangements, cash and equity incentives and operating
experience. We believe the major competitive factors in the market to provide
high speed Internet access to end users include financial, marketing and sales
resources, established customer relationships, price, ease of access and use,
transmission speed, reliability of service, quantity and quality of content,
network security and customer support. Moreover, due to intense competition,
there may be a time-limited market opportunity for our cable-based high speed
access. There can be no assurance that we will be successful in achieving
widespread acceptance of our services before competitors offer services similar
to our current offerings, which might preclude or delay purchasing decisions by
potential customers.
 
     For the reasons discussed below, we may not be able to compete successfully
against current or future competitors, and competitive pressures we face could
materially and adversely affect our business and financial results.
 
     Cable-Based Internet Access Market. Our competitors in the cable-based
Internet access market are those companies that have developed their own
cable-based services and market those services to cable system operators. In
particular, @Home, RoadRunner, the ISP Channel, Online System Services, Inc. and
Convergence.com (and their respective cable partners) are deploying high speed
Internet access services over cable networks. @Home, through its @Home Solutions
product, has begun to market to systems in the exurban market with at least
20,000 homes passed. We also compete directly with the ISP Channel and
Convergence.com in seeking to establish distribution arrangements with cable
system operators in
                                       12
<PAGE>   19
 
exurban markets and/or provide one-way system capability. In addition, other
cable system operators have launched their own cable-based Internet services
that could limit the market for our services. Many of our competitors and
potential competitors in the market for partnerships with cable operators, in
particular @Home and RoadRunner, have substantially greater financial, sales and
marketing resources, larger customer bases, longer operating histories, greater
name recognition and more established relationships with cable operators,
advertisers and content and application providers than we do.
 
     Other Technologies. Long distance inter-exchange carriers, such as AT&T,
Sprint and MCI WorldCom, have deployed large-scale Internet access networks and
sell Internet access to business and residential customers. The regional Bell
operating companies and other local exchange carriers have also entered this
field and are providing price competitive services. Many of these carriers are
offering diversified packages of telecommunications services, including Internet
access, to residential customers, and could bundle these services together,
which could put us at a competitive disadvantage. Many of these competitors are
offering (or may soon offer) technologies that will compete with some or all of
our high speed data service offerings. Such competing technologies include
integrated services digital networks and digital subscriber lines. Many of our
competitors and potential competitors, particularly regional Bell operating
companies, have substantially greater financial, sales and marketing resources
than we have, and also may compete favorably in terms of price, ease of access
and use, transmission speed and reliability of service. Other potential
competing technologies now being deployed for high speed access include wireless
and satellite data services. Widespread commercial acceptance of digital
subscriber line or other competing technologies could significantly reduce the
potential customer base for our services, which could have a material adverse
effect on our business and financial results. Additionally, as a result of the
distribution of the Darwin common stock to our current stockholders, with the
exception of the warrant we will receive from Darwin, the benefits of providing
this service will no longer accrue to our stockholders.
 
     Internet and Online Service Providers. We also compete with traditional
Internet service providers, which provide basic Internet access to residential
and commercial end users and businesses, generally using existing telephone
network. While not offering the advantages of broadband access, these services
are widely available and inexpensive. Indeed, Internet service providers
recently have announced free Internet access services. Many online service
providers, such as America Online, have the advantage of large customer bases,
industry experience, longer operating histories, greater name recognition,
established relationships with advertisers and content and application
providers, and significant financial, marketing and sales resources. Moreover,
America Online recently announced alliances with SBC Communications and Bell
Atlantic to offer AOL's services via digital subscriber line connections to be
installed by these regional Bell operating companies. The pace at which AOL and
its telephone company partners roll out DSL service could limit our ability to
attract and retain end users in areas where our service offerings overlap.
 
OUR MARKET IS CHARACTERIZED BY RAPID TECHNOLOGICAL CHANGE.
 
     The market for our services is characterized by rapid technological
advances, evolving industry standards, changes in end user requirements and
frequent new service introductions and enhancements. For example, the North
American cable industry has adopted a set of interface specifications, known as
"DOCSIS," for hardware and software to support cable-based data delivery using
cable modems. Our ability to adapt to rapidly changing technology and industry
standards, such as DOCSIS, and to develop and introduce new and enhanced
products and service offerings will be significant factors in maintaining or
improving our competitive position and our prospects for growth. If technologies
or standards applicable to our services become obsolete or fail to gain
widespread consumer acceptance, then our business and financial results will be
materially and adversely affected.
 
     We currently anticipate that we will use a significant portion of the
proceeds from this offering to acquire headend, cable modem and other related
capital equipment. The technology underlying that equipment is continuing to
evolve. It is possible that the equipment we acquire could become obsolete prior
to the time we would otherwise intend to replace it, which could have a material
adverse effect on our business and financial results.
 
                                       13
<PAGE>   20
 
OUR ABILITY TO INCREASE THE CAPACITY AND MAINTAIN THE SPEED OF OUR NETWORK IS
UNPROVEN.
 
     We face risks related to our ability to increase the transmission capacity
of our network to meet expected end user levels while maintaining superior
performance. While peak downstream data transmission speeds across the cable
infrastructure approach 10 Mbps in each 6 megahertz (Mhz) channel, actual
downstream data transmission speeds are likely to be significantly slower,
depending on a variety of factors, including the type and location of content,
Internet traffic, the number of active end users on a given cable network node,
the number of 6 Mhz channels allocated to us by our cable partner, the
capabilities of the cable modems used and the service quality of the cable
partners' facilities. The actual data delivery speed that an end user realizes
also will depend on the end user's hardware, operating system and software
configurations. There can be no assurance that we will be able to achieve or
maintain a speed of data transmission sufficiently high to enable us to attract
and retain our planned number of end users, especially as the number of the end
users grows. Because end users will share the available capacity on a cable
network node, we may underestimate the capacity we need to provide in order to
maintain peak transmission speeds. A perceived or actual failure to achieve or
maintain sufficiently high speed data transmission could significantly reduce
end user demand for our services and have a material adverse effect on our
business and financial results.
 
WE DEPEND ON A DATA TRANSMISSION INFRASTRUCTURE LARGELY MAINTAINED BY THIRD
PARTIES OR SUBJECT TO DISRUPTION BY EVENTS OUTSIDE OUR CONTROL.
 
     Our success will depend upon the capacity, reliability and security of the
infrastructure used to carry data between our end users and the Internet. A
significant portion of that infrastructure is owned by third parties.
Accordingly, we have no control over its quality and maintenance. For example,
we rely on our cable partners to maintain their cable infrastructures. We also
rely on other third parties to provide a connection from the cable
infrastructure to the Internet. Currently, we have transit agreements with UUNet
(a division of MCI WorldCom) and others to support the exchange of traffic
between our data servers, the cable infrastructure and the Internet. Our
operations also depend on our ability to avoid damages from fires, earthquakes,
floods, power losses, telecommunications failures, network software flaws,
transmission cable cuts, Year 2000 problems and similar events. The occurrence
of any of these events could interrupt our services. The failure of the Internet
backbone, our servers, or any other link in the delivery chain, whether from
operational disruption, natural disaster or otherwise, resulting in an
interruption in our operations could have a material adverse effect on our
business and financial results.
 
OUR NETWORK MAY BE VULNERABLE TO SECURITY RISKS.
 
     Despite our implementation of industry-standard security measures, our or
our cable partners' networks may be vulnerable to unauthorized access, computer
viruses and other disruptive problems. Internet and online service providers in
the past have experienced, and in the future may experience, interruptions in
service as a result of the accidental or intentional actions of Internet users.
Because the cable infrastructure is a shared medium, it is inherently more
vulnerable to security risks than dedicated telephony technologies such as
digital subscriber lines. Moreover, we have no control over the security
measures that our cable partners and end users adopt. Unauthorized access could
also potentially jeopardize the security of confidential information stored in
the computer systems maintained by us and our end users. These events may result
in liability to us or harm to our end users. Eliminating computer viruses and
alleviating other security problems may require interruptions, delays or
cessation of service to our end users, which could have a material adverse
effect on our business and financial results. In addition, the threat of these
and other security risks may deter potential end users from purchasing our
services, which could have a material adverse effect on our business and
financial results.
 
WE MAY BE HELD LIABLE FOR DEFAMATORY OR INDECENT CONTENT.
 
     The law relating to the liability of Internet and online service providers
for information carried on or disseminated through their networks is unsettled.
A number of lawsuits have sought to impose liability for defamatory speech and
indecent materials. A recent federal statute, the Children's Online Protection
Act
                                       14
<PAGE>   21
 
of 1998 ("COPA"), seeks to impose liability, in some circumstances, for the
transmission of materials that are harmful to minors, and numerous states have
adopted or are considering similar types of legislation. COPA has been
challenged by civil rights organizations in part on the grounds that it violates
the First Amendment, and a United States district court has entered a
preliminary injunction prohibiting enforcement of COPA pending final resolution
of the case. A similar federal statute was held unconstitutional by the United
States Supreme Court in 1997. At least one court has held that an online service
provider 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.
 
     Federal laws have been enacted, however, which, under certain
circumstances, may provide Internet service providers with immunity from
liability for information that is disseminated through their networks when they
are acting as mere conduits of information. A federal court of appeals has held
that the Telecommunications Act of 1996 creates immunity from liability on the
part of Internet service providers for libel claims arising out of information
disseminated over their networks by third party content providers. To the extent
we expand into international markets, however, we could be subject to even
greater potential liability, including possible criminal liability. The
imposition upon Internet or online service providers of potential liability for
materials carried on or disseminated through their systems could require us to
implement measures to reduce our exposure to liability. Such measures may
require the expenditure of substantial resources or the discontinuation of
certain products or service offerings. In addition, the imposition of liability
on us for information disseminated through our network could have a material
adverse effect on our business and financial results.
 
WE MAY BE HELD LIABLE FOR INFORMATION RETRIEVED AND REPLICATED.
 
     Because materials may be downloaded and redistributed by end users and
cached or replicated by us in connection with the offering of our services,
there is a possibility that claims may be asserted against us or our cable
partners under both U.S. and foreign law for defamation, negligence, copyright
or trademark infringement, or other theories based on the nature and content of
these materials. These types of claims have previously been brought successfully
against online service providers. In addition, copyright and trademark laws are
evolving both domestically and internationally, and it is not clear in some
cases how these laws will be applied to online environments. It is impossible
for us to determine who possesses the rights to materials distributed through
our services by third parties. The recently enacted federal Digital Millennium
Copyright Act, which creates a safe harbor from copyright infringement liability
for Internet service providers that meet certain statutory requirements, may
provide us with protection from certain copyright infringement liability claims.
However, a number of third parties have claimed that they hold patents covering
various forms of online transactions or online technologies. Patent infringement
claims relating to our services or technologies could be asserted against us. In
addition, our errors and omissions and liability insurance may not cover
potential patent or copyright infringement claims and may not adequately
indemnify us for any 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 our business and financial results.
 
WE MAY BECOME SUBJECT TO BURDENSOME GOVERNMENT REGULATION.
 
     Although our services are not currently subject to regulation by the
Federal Communications Commission (the "FCC") or any other federal or state
regulatory agency, changes in the regulatory environment affecting businesses
that provide Internet connection and content on the Internet, including
regulatory changes that, directly or indirectly, affect regulatory
classification or costs, limit usage of customer-related information or increase
the likelihood or scope of competition from the regional Bell operating
companies or other telecommunications companies, could affect the nature, scope,
prices and ability to market our services successfully. For example, the FCC has
repeatedly been asked to re-examine its classification of Internet service
providers as users, rather than providers, of telecommunications services. The
current classification of Internet service providers and their services as
enhanced or information services, which are exempt from the obligations under
which telecommunications services
 
                                       15
<PAGE>   22
 
must be provided (such as contributing to the universal service support fund and
paying carrier access charges for local connections), are being challenged by
various parties, including the regional Bell operating companies, in several FCC
and court proceedings. Legislation that could reverse or modify the FCC's
policies could be introduced in the future.
 
     The FCC's recent ruling that dial-up Internet traffic constitutes
interstate communications, and therefore is subject to the FCC's jurisdiction,
may undermine the basis for the current Internet service provider exemption from
access charges. The FCC's classification of Internet access services as
unregulated information services has also sheltered Internet telephony services
from common carrier regulation in general, and from universal service fund
obligations in particular. Some members of Congress have challenged the FCC's
conclusions exempting Internet service providers from universal service fund
contributions. In its April 8, 1998 Report to Congress in the Universal Service
proceeding, the FCC indicated that, in the future, it may begin to classify some
forms of Internet telephony as a regulated common carrier service. Future legal
or regulatory changes in the treatment of these Internet-based services may have
an adverse impact on our planned provision of Internet telephony.
 
     Currently, cable operators generally elect to classify cable-delivered
Internet services as a cable service. Consequently, cable operators are usually
required to pay cable franchise fees in connection with providing high speed
Internet access. Any change in the classification of the Internet service as a
cable service could have a material adverse effect on our business and financial
results.
 
     It is also possible that governmental authorities may attempt to classify
us in some other manner (e.g., as a common carrier-type service) and impose
additional and potentially burdensome regulatory requirements on us or our cable
partners. If cable system operators were classified as "common carriers" of
Internet services, or were to become subject to common carrier-like
interconnection or non-discrimination requirements, we could lose our status as
the exclusive residential high-speed Internet access provider over the systems
of our cable partners.
 
     Several local franchising authorities considered the imposition of open
access for Internet service providers or similar non-discrimination requirements
upon the franchise transfers sought in connection with the merger of AT&T and
Tele-Communications, Inc. ("TCI"). At least one locality imposed such a
condition on its approval of the franchise transfer, and this has resulted in
federal court litigation over the legality of this condition. Several other
local franchising authorities which approved the franchise transfers from TCI to
AT&T continue to examine the open access issue on a more general basis. The open
access issue may become prominent in future franchise renewal proceedings. If we
or our cable partners were either classified as common carriers, or otherwise
subject to common carrier-like access and non-discrimination requirements, we or
they could be subject to government-regulated terms, conditions and tariff-based
prices for Internet connection services.
 
     Local franchising authorities may attempt to subject cable systems to
higher or other franchise fees or taxes, or otherwise seek to require cable
operators to obtain additional franchises, in connection with their distribution
of our service. Because cable operators are subject to varying requirements of
each local franchise, it will be difficult or impossible for us or our cable
partners to operate under a unified set of franchise requirements. Legislation
has been enacted that imposes a moratorium on limiting the ability of state and
local governments to impose taxes on Internet services, pending the President's
submission to Congress of recommendations concerning appropriate parameters for
taxation. This legislation, however, does not affect cable franchise fees such
as those now applicable to our service.
 
     To the extent that cable-delivered Internet services are treated as cable
television services, they would be subject to the cable subscriber privacy rules
of the Cable Act. These rules contain restrictions regarding the use of cable
subscriber information. Enactment of proposed privacy legislation currently
pending in Congress, which would restrict the use of customer information by
interactive computer services for marketing and other purposes, could adversely
affect the marketing of our services as well as our advertising revenue.

     On August 8, 1998, the FCC initiated two proceedings regarding the
provision of advanced telecommunications capabilities and services. The first
was a Notice of Proposed Rulemaking, which remains pending and relates to the
terms and conditions under which incumbent local exchange carriers, such as the
regional Bell operating companies, must offer copper loops equipped for
high-speed data transmission to competing local exchange carriers. The notice
requested comment on the imposition of one or more "unbundling" obligations on
the incumbent local exchange carriers. Such obligations might well facilitate
the provision of high-speed data transmission services by competing local
exchange carriers to end users, in competition with cable-delivered services.
The notice also requested comment on a proposal to allow incumbent local
exchange carriers to form lightly-regulated entities called "Data CLEC
Subsidiaries," which would be able to obtain access to incumbent local exchange
carrier facilities on the same terms as unaffiliated competing local exchange
carriers, without the Data CLEC Subsidiaries having to meet obligations such as
unbundling and resale currently applicable to the incumbent local exchange
carrier's own operations. The FCC was prepared to act on the notice in late
January 1999, but deferred action in order to consider the impact of the Supreme
Court's January 25, 1999 decision in AT&T v. Iowa Utilities Board. That case
(among other things) requires the FCC to re-evaluate the legal standard that it
must use in determining the scope of the incumbent local exchange carriers'
unbundling obligations, and therefore affected the FCC's analysis of the
proposals in the notice.
 
     The second proceeding initiated last August was a Notice of Inquiry into
the status of deployment of advanced telecommunications capabilities pursuant to
section 706 of the Telecommunications Act of 1996. In the Inquiry, the FCC
requested comments regarding the kinds of regulatory structures that would best
foster the deployment of advanced telecommunications capabilities and that would
best fit the consumer market for such services. AOL and several other Internet
service providers advocated that they be given rights of access to broadband
systems operated by cable television companies. On February 2, 1999, the FCC
denied these requests. The FCC concluded that there was no present need to take
action because multiple methods of providing access to broadband services,
including Internet access, are or soon would be made available to a broad range
of consumers. The FCC pledged to monitor broadband deployment closely.
 
     The same access issues were raised by AOL and other Internet service
providers and telecommunications carriers opposing the merger of AT&T and TCI.
These parties requested that the FCC impose conditions on its approval of the
AT&T/TCI merger, which would have required the merger entity's cable systems to
provide access and carriage over the high-speed cable plant to unaffiliated
Internet service providers and on-line service providers. The FCC again denied
these requests while pledging to monitor broadband deployment closely. We cannot
predict the ultimate outcome of these rulemaking proceedings, the FCC's future
broadband deployment monitoring efforts, or the impact if any, that future legal
or regulatory classification changes might have on our business.
 
WE DEPEND ON OUR KEY PERSONNEL AND WE MAY HAVE DIFFICULTY ATTRACTING AND
RETAINING SKILLED EMPLOYEES.
 
     Our future success depends on the continued service of our key personnel.
We do not carry key person life insurance on most of our personnel. The loss of
the services of any of our executive officers or the loss of the services of
other key employees could have a material adverse effect on our business and
financial results. Our future success also depends on our ability to attract,
retain and motivate highly skilled employees, particularly engineering and
technical personnel. Competition for employees in our industry is intense. We
may not be able to retain our key employees or attract, assimilate or retain
other highly qualified employees in the future. From time to time we have
experienced, and we expect to continue to experience in the future, difficulty
in hiring and retaining highly skilled employees.
 
WE MAY NEED ADDITIONAL CAPITAL IN THE FUTURE.
 
     We may need to raise additional funds in the future to fund our operations,
to finance the substantial investments in equipment and corporate infrastructure
needed for our planned expansion, to enhance and expand the range of services we
offer to respond to competitive pressures and perceived opportunities, such as
investment, acquisition and international expansion activities. There can be no
assurance that additional
                                       17
<PAGE>   24
 
financing will be available on terms favorable to us, or at all. If adequate
funds are not available on acceptable terms, we may be forced to curtail or
cease our operations. Moreover, even if we are able to continue our operations,
the failure to obtain additional financing could have a material and adverse
effect on our business and financial results.
 
WE MAY DECIDE TO MAKE ACQUISITIONS OR INVESTMENTS.
 
     From time to time we have had discussions with companies regarding our
acquiring, or investing in, their businesses. If we buy a company, we could have
difficulty in assimilating its operations, or assimilating and retaining its key
personnel. These difficulties could disrupt our ongoing business, distract our
management and employees, increase our expenses and adversely affect our results
of operations due to accounting requirements such as the amortization of
goodwill or the write off of acquired in-process research and development costs.
Furthermore, we may incur debt or issue dilutive equity securities to pay for
any future acquisitions.
 
WE MAY BECOME SUBJECT TO RISKS OF INTERNATIONAL OPERATIONS.
 
     We may expand our business internationally. In doing so, we would become
subject to the risks of conducting business internationally, including:
 
     - Foreign currency fluctuations, which could result in reduced revenues or
       increased operating expenses;
 
     - Inability to locate qualified local partners and suppliers;
 
     - The burdens of complying with a variety of foreign laws and trade
       standards;
 
     - Tariffs and trade barriers;
 
     - Difficulty in accounts receivable collection;
 
     - Potentially longer payment cycles;
 
     - Foreign taxes;
 
     - Unexpected changes in regulatory requirements (including the regulation
       of Internet access); and
 
     - Uncertainty regarding liability for information retrieved and replicated
       in foreign countries.
 
     If we expand internationally, we will also be subject to general
geopolitical risks, such as political and economic instability and changes in
diplomatic and trade relationships, in connection with our proposed
international operations. There can be no assurance that the risks associated
with our proposed international operations will not materially and adversely
affect our business and financial results.
 
THE FUTURE SALE OF SHARES MAY HURT OUR MARKET PRICE.
 
     If our stockholders sell substantial amounts of our common stock (including
shares issued upon the exercise of outstanding options) in the public market
following the offering, the market price of our common stock could fall. These
sales also might make it more difficult for us to sell equity securities in the
future at times and prices that we deem appropriate. After the offering, we will
have outstanding             shares of common stock (excluding shares that may
be issued if the underwriters exercise their over-allotment option). Of these
shares, the             shares to be sold in this offering generally will be
freely tradable. Additionally, the      shares to be purchased by Cisco will be
freely tradable upon

</TABLE>
 
     We and our directors, officers, substantially all current stockholders and
Cisco have agreed not to offer to sell, sell, or otherwise dispose of, directly
or indirectly, any shares of common stock without the consent of Lehman Brothers
for a period of 180 days from the date of this prospectus.
 
     Certain stockholders, representing approximately 22,000,000 shares of
common stock, have the right, subject to specified conditions, to include their
shares in certain registration statements relating to our common stock. By
exercising their registration rights and causing a large number of shares to be
registered and sold in the public market, these holders may cause the price of
the common stock to fall.
 
THERE HAS BEEN NO PRIOR MARKET FOR OUR COMMON STOCK; OUR STOCK PRICE IS LIKELY
TO BE HIGHLY VOLATILE.
 
     Prior to the offering, there has been no public market for our common
stock. We cannot predict the extent to which investor interest in us will lead
to the development of an active trading market in our stock or how liquid that
market might become. The initial public offering price for the shares will be
determined by negotiations between us and the representatives of the
underwriters and may not be indicative of prices that will prevail in any future
trading market. The stock market has experienced extreme price and volume
fluctuations. The market prices of the securities of Internet-related companies
have been especially volatile. In the past, companies that have experienced
volatility in the market price of their stock have been the object of securities
class action litigation. If we were the object of securities class action
litigation, it could result in substantial costs and a diversion of our
management's attention and resources.
 
WE WILL HAVE BROAD DISCRETION IN USING THE PROCEEDS OF THIS OFFERING.
 
     Our management will have broad discretion over the allocation of the net
proceeds from the offering as well as over the timing of their expenditure. As a
result, investors will be relying upon management's judgment with only limited
information about its specific intentions for the use of the proceeds.
 
WE HAVE ANTI-TAKEOVER PROVISIONS.
 
     Certain provisions of our certificate of incorporation, our bylaws and
Delaware law could make it difficult for a third party to acquire us, even if
doing so might be beneficial to our stockholders.
 
NEW INVESTORS WILL INCUR IMMEDIATE AND SUBSTANTIAL DILUTION.
 
     Investors purchasing shares in the offering will incur immediate and
substantial dilution in net tangible book value per share. To the extent
outstanding options and warrants to purchase common stock are exercised, there
will be further dilution to investors.
 
WE DO NOT PLAN TO PAY DIVIDENDS IN THE FORESEEABLE FUTURE.
 
     We intend to retain any future earnings to finance the operation and
expansion of our business and do not anticipate paying any cash dividends in the
foreseeable future.

]WE FACE RISKS FROM POTENTIAL YEAR 2000 PROBLEMS.
 
     We may realize exposure and risk if the systems on which we depend to
conduct our operations are not Year 2000 compliant. Our potential areas of
exposure include the possible non-compliant status of the cable plants over
which our service operates, as well as information technology such as software
licensed products purchased from third parties and non-information technology
including telephone systems and other equipment used internally.
 
     We have engaged a third-party consultant to perform a Year 2000 assessment
study. This study will include an assessment of both our information and
non-information technology. Based on the results of this assessment, we intend
to replace or remediate non-compliant technologies and to test any replacement
or corrected technologies. We expect to receive the results of the consultant's
initial assessment by the end of May 1999.
 
     As part of our Year 2000 compliance assessment, we also will seek
verification from our cable partners, vendors and suppliers that they are Year
2000 compliant or, if they are not presently compliant, we will request a
description of their plans to become Year 2000 compliant. To the extent that
vendors fail to certify by August 30, 1999 that they are Year 2000 compliant, we
expect to terminate and replace those relationships. To the extent that our
cable partners fail to certify by August 30, 1999 that they are Year 2000
compliant, we will assess the possible impact of that failure on our business
based on the nature of our electronic interdependencies at that time, and we
will take appropriate remediation action to the extent possible or we may
suspend operations in the non-compliant system pending remediation by the cable
partner.
 
     We expect to resolve any Year 2000 compliance issues primarily through
normal upgrades of hardware and software, or, when necessary, through
replacement of existing software with Year 2000 compliant applications. We
estimate that our total cost of our Year 2000 compliance assessment will not
exceed $250,000, which will be funded from cash on hand. However, pending
receipt of the results of that assessment, the Company is unable to predict what
costs it may incur to remediate any Year 2000 problems identified.
 
     Although we believe that we can quickly address any difficulties that may
arise, in the event that our web-hosting servers and network facilities are not
Year 2000 compliant, all or portions of our Internet access services would be
unavailable to deliver services to our cable partners and end users. This in
turn could expose us to material claims and liabilities. Moreover, we do not
currently have a contingency plan to deal with the worst-case scenario that
might occur if the technologies we depend upon are not Year 2000 compliant and
fail to operate effectively. We intend to develop a plan for this scenario by
the end of the second quarter of 1999. If our present efforts to address our
potential Year 2000 compliance issues are not successful, or if our cable
partners, vendors and other third parties with which we conduct business do not
successfully address these issues, our business and financial results could be
materially and adversely affected.
 
                        SALE OF SHARES TO CISCO SYSTEMS
 
     Cisco has agreed to purchase $5 million of our common stock concurrently
with the offering at the initial public offering price per share, net of the
underwriting discount. Based on the estimated public offering price, Cisco would
purchase           shares of our common stock.
 
                                       20
<PAGE>   27
 
                                USE OF PROCEEDS
 
     We estimate the net proceeds to us from the offering, after deducting the
underwriting discounts and estimated offering expenses payable by us, and the
sale of $5 million of our common stock to Cisco, will be approximately
$          ($          if the underwriters' exercise their over-allotment option
in full), assuming an initial public offering price of $     per share.
 
     We expect to use the net proceeds of the offering to fund capital
expenditures to be incurred in the deployment of our services in new and
existing cable systems, to fund operating losses, and for working capital and
other general corporate purposes. We may also use a portion of the proceeds for
acquisitions or other investments. However, we have no present understanding or
agreement relating to any material acquisition or investment.
 
     We have not yet determined the amount of net proceeds to be used
specifically for each of the foregoing purposes. Accordingly, management will
have significant flexibility in applying the net proceeds of the offering.
Pending their use, we intend to invest the net proceeds of the offering in high
quality, interest-bearing instruments. See "Risk Factors -- We may decide to
make acquisitions or investments" and "-- We will have broad discretion in using
the proceeds of this offering."
 
                                DIVIDEND POLICY
 
     We have not declared or paid any cash dividends on our capital stock since
inception and we do not expect to pay cash dividends for the foreseeable future.
We currently intend to retain future earnings, if any, to finance the expansion
of our business.

     The following table sets forth our capitalization as of December 31, 1998.
Our capitalization is presented:
 
     -   On an actual basis; and
 
     -   On a pro forma basis to reflect:
 
        -   the sale of the           shares offered hereby at an assumed
            initial public offering price of $     per share, after deducting
            underwriting discounts and estimated offering expenses payable by
            us;
 
        -   the sale of an estimated           shares of common stock to Cisco
            at the assumed initial public offering price, net of the
            underwriting discount;
 
        -   the automatic conversion of all outstanding shares of Series A and
            Series B convertible preferred stock into 15 million shares of
            common stock concurrently with the completion of the offering; and
 
        -   the sale to Vulcan Ventures at $5.00 per share of 5 million shares
            of Series C convertible preferred stock and the automatic conversion
            of those shares into 5 million shares of common stock concurrently
            with the completion of the offering.
 
     You should read this information in conjunction with our financial
statements appearing elsewhere in this prospectus, and with the sections of the
prospectus entitled "Selected Financial Data" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."

                                    DILUTION
 
     As of December 31, 1998, our net tangible book value on a pro forma basis
giving effect to the sale of $25 million of preferred stock before completion of
the offering and the conversion of all our convertible preferred stock into
common stock upon consummation of the offering was $     million or $     per
share of common stock. "Net tangible book value" per share represents the amount
of our total tangible assets reduced by the amount of our total liabilities,
divided by the number of shares of common stock outstanding. As of December 31,
1998, our net tangible book value, on a pro forma basis as further adjusted for
the sale of the           shares offered in the offering (after deducting the
underwriting discounts and commissions and other estimated offering expenses)
and an estimated           shares to be sold to Cisco, and application of the
net proceeds from such sales of $     million, would have been approximately
$     per share. This represents an immediate increase of $     per share to
existing shareholders and an immediate dilution of $     per share to new
investors. The following table illustrates this per share dilution:

                            SELECTED FINANCIAL DATA
            (DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
     The selected historical data has been derived from financial statements
audited by PricewaterhouseCoopers, LLP, independent accountants. The
consolidated balance sheet at December 31, 1998 and the related consolidated
statement of operations and of cash flows for the period from April 3, 1998
(Inception) through December 31, 1998 and notes thereto appear elsewhere in this
prospectus.
 
     We prepared the unaudited pro forma financial information for the year
ended December 31, 1998 by combining the historical results of the two companies
we acquired, High Speed Access Network, Inc. and CATV.net, Inc., with our
historical results. We have presented this information to give you a better
picture of what our business might have looked like if we had acquired both of
these companies as of January 1, 1998. These companies may have performed
differently if they had been combined with our operations. You should not rely
on the unaudited pro forma information as being indicative of the historical
results that we would have had or the future results that we will experience
after the acquisitions.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion of our financial condition and results of
operations should be read together with the financial statements included in
this prospectus. This discussion contains forward-looking statements that
involve risks and uncertainties. Our actual results may differ significantly
from those anticipated in these forward-looking statements as a result of
factors including, but not limited to, those set forth under "Risk Factors" and
included in other portions of this prospectus.
 
OVERVIEW
 
     We are a leading provider of high speed Internet access via cable modem to
residential and commercial end users in exurban areas. We generate revenue
primarily from the monthly fees we receive from end users for our cable
modem-based Internet access service and for the traditional dial-up services we
offer as part of our end user acquisition strategy. We report these revenues net
of the percentage split we pay to our cable partners. For promotional purposes,
we often provide new end users with 30 days of free Internet access when they
subscribe to our services. As a result, our revenue does not reflect new end
users until the end of the promotional period. We also receive revenues from
renting cable modems to end users. Although we also earn revenues from the
one-time fees we charge for the installation of the cable modem at the end
user's home or business, we frequently waive this fee.
 
     Our revenue from dial-up services currently is a significant part of our
total revenue. However, we expect this business mix to shift over time as our
dial-up end users migrate to high speed Internet access and as end users
generally become aware of the benefits of high speed Internet access. Moreover,
although we expect cable modem rentals to be a significant part of our revenue
during the next two years, we expect our cable modem rental income to decline
eventually as cable modems become commercially available at lower costs through
retail stores and as they become standard features of personal computers.
However, we will save the cost of purchasing and installing cable modems for end
users. In the future we expect to earn revenues from the local content we
provide and from additional services such as Internet telephony.
 
     Our expenses consist of the following:
 
     - Operating costs, which consist primarily of salaries for help desk and
       network operations center employees; telecommunications expenses,
       including charges for Internet backbone and telecommunications circuitry;
       allocated cost of facilities; costs of installing cable modems for our
       end users; and depreciation and maintenance of equipment. In one-way
       cable systems, we must support the telephone return path from the end
       user to the cable headend. Accordingly, we incur greater
       telecommunications costs in a one-way system than we incur in a two-way
       system. Consequently, the rate at which our cable partners upgrade their
       systems to two-way capability will affect our operating margins. We
       expect our operating costs to grow significantly as we roll out services
       in new systems. Many of our operating costs are relatively fixed in the
       short term. However, as we add new end users we will be able to spread
       these costs over a larger revenue base, and, accordingly, decrease our
       costs per subscriber and improve our operating margins.
 
     - Engineering expenses, which consist primarily of salaries and related
       costs for network design and installation of the telecommunications and
       data network hardware and software; system testing and project management
       expenses; allocated cost of facilities; and depreciation and maintenance
       on the equipment used in our engineering processes. We expect our
       engineering expenses to grow significantly as we introduce our services
       in new markets and expand our network.
 
     - Sales and marketing expenses, which consist primarily of salaries,
       commissions and related personnel expenses and costs associated with the
       development of sales and marketing materials, database market analytics,
       direct mail and telemarketing. We expect that our sales and marketing
       expenses will increase significantly as we pursue our growth strategy.
 
     - General and administrative expenses, which consist primarily of salaries
       for our executive, administrative, finance and human resource personnel;
       amortization of goodwill; and fees for
                                       27

professional services. We expect to hire additional support personnel and to
incur other additional expenses associated with being a public company,
including costs of directors' and officers' insurance, and increased legal and
      accounting fees.
 
     Under our 1998 stock option plan we have granted options to purchase
142,900 shares of common stock for $5.00 per share, which is below the market
value of our common stock. Non-cash compensation expense related to these
in-the-money options is currently being amortized over the five-year vesting
period of the options, but the remainder of the non-cash expense will be
recognized immediately upon the completion of the offering, at which time the
options immediately vest. It is also likely that we will recognize non-cash
stock option compensation expense in future periods related to the currently
outstanding options to purchase 122,500 shares of common stock granted under our
1999 non-employee directors' stock option plan.
 
RESULTS OF OPERATIONS FOR THE PERIOD APRIL 3, 1998 (INCEPTION) TO DECEMBER 31,
1998
 
     On April 3, 1998, we acquired CATV.net, Inc. and High Speed Access Network,
Inc. in a transaction recorded under the purchase method of accounting. We had
no operations prior to that acquisition. Accordingly, the following discussions
reflects our results of operations since April 3, 1998.
 
  Revenues.  Net revenue was $337,000 for the period. Net revenue consists
primarily of net monthly subscription fees for cable modem-based and traditional
dial-up Internet services, and cable modem rental income.
 
  Costs and Expenses
 
     Operating. Operating costs were $2.1 million for the period. During the
period, we hired personnel to staff our network operations center and help desk
on a full-time basis. Telecommunications expenses were significant for the
period as we rolled out our service to new markets.
 
     Engineering. Engineering expenses were $2.3 million for the period. During
the period we hired additional technical personnel to support the installation
of cable headend hardware and software in our cable partners' systems. We also
incurred significant expenses for network design system testing and project
management, and for evaluation of new equipment and possible new product
offerings.
 
     Sales and Marketing. Sales and marketing expenses were $3.7 million for the
period. During the period we incurred substantial sales and marketing expenses,
primarily due to the expansion of our sales force, related travel and
entertainment expenses, and marketing activities associated with gaining
residential and commercial end users and new cable partners, including
expenditures for trade shows and advertising.
 
     General and Administrative. General and administrative expenses were $2.3
million for the period. During the period we hired personnel to implement
procedures and controls to support our planned expansion. General and
administrative expenses for the period also included amortization of goodwill of
$626,000 resulting from our acquisitions of CATV.net and High Speed Access
Network.
 
  Net Interest Income.  Net interest income was $40,000 for the period. Net
interest income represents interest earned by us on our cash and short-term cash
investments, less interest expense on capital lease obligations and notes
payable.
 
  Income Taxes.  At December 31, 1998, we had net operating loss carryforwards
for federal and state tax purposes of approximately $8.5 million, which will
expire at various times through 2018. At December 31, 1998, we had a net
deferred tax asset of $3.8 million relating principally to our net operating
loss. Our ability to realize the value of our deferred tax asset depends on our
future earnings, if any, the timing and amount of which are uncertain. We have
recorded a valuation allowance for the entire net deferred tax asset as a result
of those uncertainties. Accordingly, we did not record any income tax benefit
for net losses incurred for the period.

</TABLE>
 
     Net revenues increased in each quarter of 1998 as a result of the expansion
of our services.
 
     Quarterly expenses increased sequentially during 1998 as a result of
increased business activities. As our Internet access service has been initiated
in additional geographic areas, we have incurred added marketing, customer
service, personnel, and telecommunications expenses. We believe continued
expansion of our operations, as well as expansion of our Internet backbone
network, is critical to the achievement of our goals and we anticipate that
these costs and expenses will continue to increase in each quarter for the
foreseeable future.
 
     Our operating results have varied on a quarterly basis during our short
operating history and may fluctuate significantly in the future. In addition,
the results of any quarter do not indicate the results to be expected for a full
fiscal year. Finally, as a result of the foregoing factors, our annual or
quarterly results of operations may be below the expectations of public market
analysts or investors, in which case the market price of the common stock could
be materially and adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     We had significant negative cash flows from operating activities for the
period ended December 31, 1998. Cash used in operating activities for the period
was $5.8 million. In 1998, the use of cash was primarily due to a net loss of
$10.0 million and an increase in current assets of $142,000, offset by non-cash
expenses of $1.3 million and increases in accounts payable and accrued expenses
of $2.8 million.
 
     Cash used in investing activities for the period was $4.8 million. Cash
used for investing activities was primarily the result of capital expenditures
for equipment and software, furniture and fixtures. Gross capital expenditures
for equipment and software, furniture and fixtures were $5.7 million and
$907,000 was funded with cash acquired in the acquisition of CATV.net and High
Speed Access Network.
 
     Cash provided by financing activities during 1998 was $28.4 million
resulting primarily from $27.6 million in net proceeds from the issuance of
convertible preferred stock in the period.
 
                                       29
<PAGE>   36
 
     We expect to experience substantial negative cash flow from operating
activities and negative cash flow from investing activities for at least the
next several years due to continued deployment of our services into new markets
and the enhancement of our network and operations. Our future cash requirements
will depend on a number of factors including: (1) the number of markets entered;
(2) the timing of entry and services offered; (3) the rate at which subscribers
purchase our services and the pricing of such services; (4) the level of
marketing required to acquire new subscribers and cable operator partners; (5)
the rate at which we invest in upgrading and maintaining our network and future
technologies; (6) changes in revenue splits with our cable partners; and (7)
price competition in the Internet and cable industries. We expect to incur
between $15 million and $20 million of capital expenditures in 1999. Actual
capital expenditures will be significantly affected by the rate at which end
users subscribe for our cable modem Internet access services, which requires us
to purchase a cable modem for each new end user, as well as by the pace of the
roll out of our systems.
 
     Since inception, we have financed our operations primarily through a
combination of private sales of equity securities and capital equipment leases.
At December 31, 1998, the primary source of liquidity for the Company was $17.9
million of cash and cash equivalents. We believe that the net proceeds from this
offering, together with existing cash, $5 million in proceeds from the sale of
common stock to Cisco, $25 million in proceeds from the planned sale of 5
million shares of Series C convertible preferred stock to Vulcan Ventures, which
will be converted into 5 million shares of common stock upon consummation of
this offering, and capital lease financing will be sufficient to meet our
working capital requirements, including operating losses, and capital
expenditure requirements for at least the next 18 months. There can be no
assurance that we will be able to raise additional capital, should that become
necessary, on terms acceptable to us or at all. The sale of additional equity or
convertible debt securities may result in additional dilution to our
stockholders. If financing is not available at terms acceptable to us,
management has the intent and the ability to reduce expenditures so as to delay
the need for additional financing.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In April 1998 the AICPA issued Statement of Position 98-5, Reporting on the
Costs of Start-Up Activities (SOP 98-5). SOP 98-5, which is effective for fiscal
years beginning after December 15, 1998, provides guidance on the financial
reporting of start-up costs and organization costs. It requires costs of start
up activities and organization costs to be expensed as incurred. As the Company
has expensed these costs historically, the adoption of this standard is not
expected to have a significant impact on the Company's results of operations,
financial position or cash flows.
 
     In June 1998 the FASB issued Accounting for Derivatives and Hedging
Activities (SFAS 133), which establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives) and for hedging
activities. SFAS No. 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. As the Company does not currently engage or plan
to engage in derivative or hedging activities, there will be no impact to the
Company's results of operations, financial position or cash flows upon the
adoption of SFAS 133.
 
YEAR 2000 COMPLIANCE
 
     We may realize exposure and risk if the systems on which we depend to
conduct our operations are not Year 2000 compliant. Our potential areas of
exposure include the possible non-compliant status of the cable plants over
which our service operates, as well as information technology such as software
licensed and products purchased from third parties, and non-information
technology including telephone systems and other equipment used internally.
 
                                       30
<PAGE>   37
 
     We have engaged a third-party consultant to perform a Year 2000 assessment
study. This study will include an assessment of both our information and
non-information technology. Based on the results of this assessment, we intend
to replace or remediate non-compliant technologies and to test any replacement
or corrected technologies. We expect to receive the results of the consultant's
initial assessment by the end of May 1999.
 
     As part of our Year 2000 compliance assessment, we also will seek
verification from our cable partners, vendors and suppliers that they are Year
2000 compliant or, if they are not presently compliant, we will request a
description of their plans to become Year 2000 compliant. To the extent that
vendors fail to certify by August 30, 1999 that they are Year 2000 compliant, we
expect to terminate and replace those relationships. To the extent that our
cable partners fail to certify by August 30, 1999 that they are Year 2000
compliant, we will assess the possible impact of that failure on our business
based on the nature of our electronic interdependencies at that time, and we
will take appropriate remediation action to the extent possible or we may
suspend operations in the non-compliant system pending remediation by the cable
partner.
 
     We expect to resolve any Year 2000 compliance issues primarily through
normal upgrades of hardware and software, or, when necessary, through
replacement of existing software with Year 2000 compliant applications. We
estimate that our total cost of our Year 2000 compliance assessment will not
exceed $250,000, which will be funded from cash on hand. However, pending
receipt of the results of that assessment, the Company is unable to predict what
costs it may incur to remediate any Year 2000 problems identified.
 
     Although we believe that we can quickly address any difficulties that may
arise, in the event that our web-hosting servers and network facilities are not
Year 2000 compliant, all or portions of our Internet access services would be
unavailable to deliver services to our cable partners and end users. This in
turn could expose us to material claims and liabilities. Moreover, we do not
currently have a contingency plan to deal with the worst-case scenario that
might occur if the technologies we depend upon are not Year 2000 compliant and
fail to operate effectively. We intend to develop a plan for this scenario by
the end of the second quarter of 1999. If our present efforts to address our
potential Year 2000 compliance issues are not successful, or if our cable
partners, vendors and other third parties with which we conduct business do not
successfully address these issues, our business and financial results could be
materially and adversely affected.

                                    BUSINESS
 
OVERVIEW
 
     We are a leading provider of high speed Internet access via cable modem to
residential and commercial end users in exurban areas. We believe that we
provide the most comprehensive turnkey service available in exurban markets. Our
service enables subscribers to receive Internet access at speeds substantially
faster than traditional Internet access at minimal cost to the cable operator.
We enter into long term exclusive contracts with cable operators to provide them
with our service. In exchange for providing us access to their customers, we pay
our cable partners a portion of the monthly fees we receive from the end users.
 
     We have exclusive agreements to provide our services to 11 cable operators,
covering 43 systems and approximately 868,000 homes passed. We also have
exclusive letters of intent to provide these services to another 23 operators
representing an additional 30 systems and approximately 230,000 homes passed. We
have commenced full operations in 14 systems covering approximately 210,000
homes marketed, initiated operations in 16 systems covering an additional
276,000 homes, and have approximately 2,800 cable modem end users.
 
     Vulcan Ventures, Incorporated, an affiliate of Microsoft co-founder Paul
Allen, beneficially owns 54.2% of our common stock before the offering. Vulcan
also owns Charter Communications, Inc., the seventh largest cable system
operator in the United States. Charter has agreed to provide us with exclusive
access to at least 750,000 homes passed and Vulcan has an equity incentive to
cause Charter to provide us up to an additional 5 million homes passed.
 
MARKET OPPORTUNITY
 
     We seek to provide our services to the rapidly expanding number of
households and businesses in the United States that are online. According to
industry analysts, there were 26.5 million households with Internet access in
the United States in 1998. Industry analysts expect this number to grow to
nearly 58.4 million households by the end of 2002. One recent industry report
estimated that, by the end of 2002, 15.8 million U.S. households will have
broadband Internet access. We believe that cable modems will become the leading
method of high speed Internet access for residential end users.
 
     Our target exurban market, defined as cable systems with fewer than 100,000
homes passed, encompasses approximately 48 million of the 95.4 million U.S.
households passed by the cable infrastructure. Our target market also includes
businesses and other establishments, such as hospitals, hotels, local
governments, universities and colleges, churches, and multiple dwelling units.
We have exclusive agreements giving us the right to provide high speed Internet
access to approximately 868,000 homes passed and we have letters of intent
relating to approximately 230,000 additional homes passed.
 
     Of the 48 million homes passed in the exurban market, approximately 27.8
million are within systems owned by operators who have entered into agreements
for high speed Internet access with @Home or Roadrunner. Although several of the
operators who have contracted with @Home and Roadrunner have committed all of
their systems to them, we believe that some of these operators have contracted
with @Home and Roadrunner on a system-by-system basis. We believe we have an
opportunity to provide our services to those operators in their uncommitted
systems. For example, Marcus Cable, prior to the announcement of its acquisition
by Charter, had entered into an agreement with @Home covering its Ft. Worth,
Texas cable system and had entered into a letter of intent with us for its Eau
Claire, Wisconsin system. Moreover, even when an operator has committed all its
systems to one of our competitors, we believe there is still an opportunity for
us if our competitors are not adequately addressing the needs of their cable
partners. Therefore, we believe there may be an opportunity for us to provide
our service in some of these exurban markets by partnering with the cable
operator directly or with other high speed Internet access providers.
 
                                       32
<PAGE>   39
 
     The remaining 19.1 million households in our target exurban market
(excluding markets we have under contract or letter of intent) are located in
systems owned by operators that are using one of our smaller competitors, not
currently providing high speed Internet access, or providing high speed Internet
access without the assistance of a high speed access provider. We believe that
our full turnkey solution is particularly appealing for those operators not yet
offering high speed Internet access. In addition, operators currently providing
their own Internet access may prefer to use our services to eliminate the
capital and operating costs associated with providing high speed Internet
access.
 
     The foregoing discussion of our target exurban market is based on data
compiled by Warren Publishing's 1998 Cable and TV Factbook and is as of October
1997. Since October 1997, there have been numerous changes in the cable
industry, including continued consolidation and cable system swaps. However,
based on management's knowledge of the cable industry, we do not believe these
subsequent events have materially changed the size or composition of, or
competitive conditions in, the exurban market.
 
THE HSA SOLUTION
 
     We believe our full turnkey service is uniquely responsive to the needs of
cable operators and end users in the large and currently underserved exurban
market. We earn our revenues primarily from monthly subscription fees paid by
the end user, a portion of which we share with our cable partners. Therefore, to
be successful, we must provide an attractive service to both our cable partners
and to our end users.
 
  CABLE OPERATOR
 
     Our management team has extensive experience in all aspects of the cable
business, including sales and marketing, engineering, operations and product
development. We believe this experience provides a unique perspective that has
allowed us to tailor our solution to meet the needs of cable operators.
 
     Full Turnkey Solution Requiring Minimal Effort by the Cable Operator.  We
believe we offer the most comprehensive solution of its kind available to cable
operators. We are responsible for all aspects of our Internet access system. Our
local cable partners' only responsibilities are to provide space in the headend
for our equipment, allow us to access the necessary bandwidth to provide our
services and to maintain the integrity and performance of the cable plant.
Specifically, we provide:
 
     - Detailed roll-out plan and network design;
 
     - Purchase and installation of the telecommunications and data network
       hardware and software necessary to offer our services;
 
     - System testing and project management;
 
     - Arrangements for the installation of a cable modem at the end user's home
       or business;
 
     - Connection to, and maintenance of, our Internet backbone system;
 
     - On-going local and corporate-level sales and marketing efforts;
 
     - 24-hour, seven-days-a-week help desk assistance for end users;
 
     - 24-hour, seven-days-a-week monitoring of our network and our cable
       partner's cable plant; and
 
     - Direct customer billing.
 
     Rapid Implementation of High Speed Access In Either Upgraded or
Non-Upgraded Systems.  We believe we provide not only the most comprehensive
means for a cable operator to implement high speed access services, but also one
of the most expedient. Implementation generally begins immediately after we sign
a letter of intent for network services. Based on our extensive experience in
the 30 cable systems we have installed to date and our standardized
implementation and engineering process, we target full implementation within 90
days after the cable operator authorizes us to deploy our services, and often
are able to complete it sooner. In addition, because we do not require the cable
operator to upgrade its system to two-way capability, we can deploy one-way
broadband access to some communities sooner than many of
 
                                       33
<PAGE>   40
 
our competitors. However, two-way capability allows a cable operator to provide
other valuable services, such as interactive program guides, impulse
pay-per-view, video on demand and telephony. Our services and the related
revenue may serve as an impetus for a cable operator to upgrade its system to
two-way capability, which could have other benefits for the operator.
 
     Source of Additional Revenues With Minimal Associated Operating or Capital
Cost.  In addition to splitting monthly fees with the cable operator, we offer
cable operators incremental revenue opportunities from local content provided
through our services. We also provide non-cable services such as residential
Internet access through dial-up and other feeder technologies, as well as
commercial Internet access, the revenues from which we also share with our cable
partners. In addition, we also expect to provide our cable partners with revenue
streams from future broadband services, such as Internet telephony services,
video conferencing, home alarm, child care and utility monitoring, local and
community-based e-commerce and interactive video games.
 
     Dedicated On Site and National End User Marketing Provided by Us.  Our
management team has experience in marketing high speed Internet access and,
unlike our major competitors, we assume primary responsibility for selling our
services to end users. Our dedicated national marketing effort includes the
development of sales and marketing materials, database market analytics, direct
mail and centralized telemarketing. Additionally, we typically maintain a local
manager and sales staff in each service area to focus on commercial sales and to
coordinate with corporate-level residential sales and marketing programs.
 
     Additional Benefits to the Cable Operators.  We provide cable operators
24-hours-a-day, seven-days-a-week network monitoring. We continuously
troubleshoot and monitor for problems over the cable infrastructure that could
cause an interruption of cable service or Internet access. Our product enables
the local cable operator to provide, generally under its own name, high speed
Internet access services and local content and community information equal to or
exceeding similar services offered in many major metropolitan areas. We believe
our services will increase cable penetration and enhance the operator's
reputation in the community, which may make it easier for the operator to obtain
renewal of its cable franchise.
 
  END USERS
 
     Residential
 
     We believe our services are attractive to residential end users for the
following reasons:
 
     High Speed Access.  We offer the end user Internet access at transmission
speeds up to 10 Mbps compared to standard 56 Kbps dial-up access. Our high speed
access allows end users to more efficiently use bandwidth-intensive multimedia
applications (such as interactive games, high-quality audio and distance
learning) and online commerce applications (such as retailing, financial
services and online software distribution).
 
     User Friendly, Always-on Internet Access.  In a two-way cable system, we
provide the end user with Internet access that is always on, eliminating the
inconvenience associated with timing out of telephone modem connections, and
generally avoiding the need for dial-up procedures. Additionally, unlike
standard dial-up access, the high bandwidth nature of cable allows our end users
to maintain full use of their telephone and television while online.
 
     Superior Price/Performance.  Cable-based Internet access currently provides
significantly greater speeds at costs to the end user equal to, or less than,
alternative high speed technologies such as ISDN, DSL, and potentially wireless
and satellite. Moreover, ISDN and DSL services are not currently available in
many exurban markets as the technology is better suited to densely populated
areas. In two-way cable systems, the cost of our services to the end user is
approximately the cost of dial-up Internet access plus the cost of an additional
telephone line.
 
                                       34
<PAGE>   41
 
     Local Content and Online Communities.  We aggregate and provide local
content online. We believe local content will be popular in communities where
local news and information may not be available online or from a single source.
We focus on local news, sports, weather, education, government and community
events that may not be available online or from a single source. We intend to
create local online communities using customized home pages, community chat
rooms and local e-commerce sites.
 
     Commercial
 
     Our services provide the commercial end user in exurban markets with the
most cost effective solution available for high speed Internet access as a
result of our scalable bandwidth and the capabilities of the cable plant. Our
target commercial market includes businesses, local governments, hospitals,
hotels, universities and colleges, churches and multiple dwelling units. The
benefits for commercial end users include:
 
     Reliable, Low-cost Internet Gateway.  Our technology provides high quality,
reliable Internet access suitable for commercial end users often at a
significant savings to telephone-based Internet access options. In some of our
markets, for example, the only other broadband alternative for businesses is the
installation of expensive circuitry by the local telephone company.
 
     Scalable Bandwidth.  We have the ability to offer varying bandwidths to a
commercial end user, depending on its needs. We currently offer bandwidths of up
to 10 Mbps for our commercial customers. We plan to provide greater bandwidth
offerings over time, based on demand.
 
     Value Added Business Services.  Our high bandwidth capability allows us to
offer commercial end users value added services such as virtual private
networks. Virtual private networks allow a business to extend its corporate
network to remote employees and external organizations. Services such as virtual
private networks allow hospitals, universities and small businesses to have the
benefits of a dedicated wide-area network, including high speed and security, at
a fraction of the cost of a traditional network. For example, in Eau Claire,
Wisconsin, we provide virtual private network services to the University of
Wisconsin for use by students in telecommuting. We also offer commercial
Internet services, such as e-mail, news groups and web hosting. In the future,
our commercial services may include Internet telephony, which is a means of
using the Internet to connect a company's local telephone network to remote
users, such as telecommuters. We also plan to offer commercial end users gateway
telephony, which involves using the Internet for secure, reliable, long-distance
communications.
 
     Alternative Technologies.  In markets where we offer our cable-based
services and a commercial end user does not have direct access to the cable
infrastructure, we are "technology agnostic." We are capable of using
alternative technologies such as wireless or DSL connections to link a business
to the cable headend. We intend to deploy these alternative technologies in
partnership with our cable partners.
 
STRATEGY
 
     Our objective is to be the leading provider of high speed Internet access
in exurban markets. Our strategy has the following key elements:
 
     Focus on the Exurban Market Where There is Less Competition and Cable
Operators Have a Greater Need for Our Turnkey Services. Exurban markets include
small cities and towns, as well as suburban communities with fewer than 100,000
homes passed. We believe the exurban market offers a substantial opportunity
because:
 
     - It represents a large underserved market segment;
 
     - Cable system operators in these markets typically have a greater need for
       the full turnkey solution we offer, including our technical expertise and
       comprehensive sales and marketing program;
 
     - Management believes the potential penetration in these markets may be
       higher than in urban markets; and
 
                                       35
<PAGE>   42
 
     - We can gain the substantial advantage of being first to market in many
       exurban cable systems because our services are compatible with two-way,
       one-way and migrating cable systems.
 
     Although the exurban market is our primary focus, from time to time we may
consider opportunities to service larger markets to the extent we believe it is
economically attractive to do so.
 
     Rapidly Expand Our Base of Cable Partners. We have installed 30 systems,
covering 486,000 homes passed, and we have contracts or letters of intent to
deploy our services in an additional 43 systems, covering 611,000 homes passed,
in the United States. We have a dedicated team of experienced cable industry
professionals who are actively marketing to the largest 100 cable multiple cable
system operators, as well as to other independent cable operators.
 
     Offer a Full Turnkey Value Proposition to the Cable Operator and Create
Long Term Partnerships. We have designed our services to offer substantial value
to cable operators. We believe we provide a more complete and valuable service
than any of our competitors and that our service is particularly well suited to
exurban markets. The elements of our service include:
 
     - A comprehensive full turnkey service, including the purchase of capital
       equipment, local installation, local on-site and corporate-level
       marketing, a network operations center to monitor performance and
       optimization of the system, and direct customer billing;
 
     - Extensive experience in the cable industry, allowing us to anticipate and
       meet the needs of cable operators;
 
     - The flexibility to support cable systems that have not been partially or
       fully upgraded to provide two-way service;
 
     - The ability to use alternative technologies, such as DSL and wireless, to
       connect commercial customers to the cable headend, to increase the base
       of revenue sharing end users for the cable operator; and
 
     - The potential to deliver additional high bandwidth services to end users,
       such as virtual private networks, Internet telephony, gateway telephony,
       and network computer and Web TV(R)-like broadband access.
 
     Based on our full turnkey service, superior marketing and capital
investments we expect to create long-term partnerships with our cable partners.
Once a cable operator implements services under an exclusive arrangement in a
specific cable system, we believe a significant barrier to entry is created in
that system.
 
     Provide a Range of Products and Services to Residential and Commercial End
Users. We strive to deliver a range of products and services to our end users.
We provide our services over both one-way systems, two-way systems and systems
in the process of being upgraded. As a "feeder" in those markets where we offer
high speed Internet access, we also offer standard 56 Kbps dial-up access and in
the future may offer other entry level Internet access technologies, such as Web
TV(R)-like broadband access and network computers. Our feeder strategy provides
consumers new to the Internet, or unfamiliar with the benefits of high speed
access, the option of initiating the most basic level of Internet access, and
upgrading their level of service over time. For commercial end users we provide
high speed Internet access with bandwidth alternatives ranging from 500 Kbps to
10 Mbps. We also offer virtual private network services to commercial end users,
as well as commercial Internet service provider facilities, such as e-mail and
web hosting. In the future our commercial services may include Internet
telephony and gateway telephony.
 
     Increase End User Penetration through Dedicated Marketing and Local
Content. We believe our focus on end user marketing, combined with our
specialization in broadband access services, will increase market penetration.
We use traditional marketing techniques such as print, radio, television and
cable system mailers. More importantly, we employ sophisticated database
marketing and telemarketing techniques and employ sales personnel in the field.
We believe our local presence and our local community programming
 
                                       36
<PAGE>   43
 
and content, together with our plans to provide online local content and online
local communities will both attract and retain end users.
 
     Leverage Economies of Scale Inherent in Our Business. As we increase our
installed base of systems, we expect to realize economies of scale at both the
local and national level, the benefits of which we will be able to share with
our cable partners. We actively seek to create a cluster of systems in a
geographic region, allowing us to economically serve a number of smaller cable
systems. Nationally, we can spread the costs of centralized services such as the
network operations center, customer service and help desk over a larger end user
base, obtain better volume pricing discounts for equipment, and lower our
telecommunications cost as the level of traffic increases. As we install more
systems, we gain valuable cumulative experience which allows us to increase the
rate of penetration, increase the speed and reliability of our system
installations and reduce costs.
 
     Leverage the Media and Cable Industry Experience of Our Investors,
Directors and Management. We also expect to capitalize on our sponsoring
investors' media and cable industry experience. For example, Vulcan Ventures,
our largest stockholder, owns Charter Communications, the seventh largest cable
system operator in the United States and has substantial investments in media,
Internet and new media companies, including USA Networks, ZDTV, Beyond.com, N2K,
Inc., Wink Communications, Inc., Value America, Inc. and Priceline.com.
Moreover, certain of the principals of Broadband Solutions, which founded the
company, co-founded and invested in Premier Parks Inc., Regal Cinemas, Inc. and
Regent Communications, Inc. We believe that our sponsor group and their
knowledge of and extensive connections in the media and cable industries help
position us to compete in the high speed cable modem Internet access market.
 
     Selectively Explore International Expansion and Domestic Acquisition
Opportunities. Although international expansion is not our primary focus, we
will selectively evaluate potential international expansion opportunities as
they become available to capitalize on the growing worldwide demand for high
speed Internet access. If we expand internationally, we will do so only if we
can work with a qualified local partner. In addition, primarily as a customer
acquisition feeder strategy, we will selectively evaluate potential acquisitions
of local Internet service providers in a current cable market to help further
expand our base of potential high speed access end users. For example, we are in
discussions to acquire approximately 1,800 dial-up customers in one of our
existing markets.
 
PRODUCTS AND SERVICES
 
     We offer the following products and services:
 
     Residential High Speed Internet Access. We offer our basic high speed
Internet service to residential end users for a monthly fee of typically less
than $40, which approximates the monthly fee for standard dial-up Internet
access plus the cost of a second phone line. Monthly service includes unlimited
access time, multiple e-mail accounts and Web browser software. We also provide
10 hours of standard dial-up Internet access per month to the end user who
wishes to access the Internet while away from home. In addition, we typically
rent cable modems to the residential end user for $9.95 per month. Our high
speed access services are available to end users in two-way cable systems,
one-way systems or migrating systems. A two-way cable system provides always-on
access and does not require the use of a phone line to transmit data from the
home to the Internet. In pricing our services, we do not differentiate between
end users in one-way and two-way systems, although we incur higher costs in a
one-way system because we must support the telephone return component. As a
cable operator upgrades its system to two-way, we incur only a minimal one-time
cost because we can reprogram our software remotely. Once a system is upgraded,
our telecommunications costs for that system typically decrease.
 
     Residential Entry Level Internet Access. As a feeder for our high speed
Internet access service, in markets where we provide our cable-based access
service, we also offer standard 56 Kbps dial-up access, and may in the future
offer other entry level Internet access technologies such as Web TV(R)-like
devices and network computers. Our dial-up alternative represents a customer
acquisition strategy that provides consumers new to the Internet, or unfamiliar
with the benefits of broadband access, the option of initiating
                                       37
<PAGE>   44
 
the most basic level of Internet access, and upgrading their level of service
over time. We expect that over time end users will upgrade their level of
service as they experience the slow transmission speeds associated with standard
dial-up access, as their needs increase, or as additional bandwidth-intensive
multimedia applications emerge. Monthly fees for feeder services, which we share
with our cable partners, are priced competitively with other "narrowband"
Internet service providers and provide us an incremental source of revenue at
very low cost.
 
     Commercial High-Speed Internet Access. We provide high speed Internet
access to commercial end users for a monthly fee that varies based on the level
of service. Our commercial end users may choose bandwidth alternatives ranging
from 500 Kbps to 10 Mbps. We have the ability to track the end user's usage to
determine when a bandwidth upgrade may be appropriate. We currently offer
e-mail, web hosting, news groups, telecommuting packages and virtual private
network services to commercial customers. In markets where we offer our
cable-based services, if a business does not have direct access to the cable
infrastructure, we are "technology agnostic." We are capable of using
alternative technologies, such as wireless or DSL connections, to link
commercial end users to the cable headend.
 
     Local Content. We provide local content targeting the interests of local
communities, including civic, commercial and school related issues, and
information on local services, including shops, restaurants and events currently
not focused on by national, regional or city-wide content aggregation services.
We believe local content will be popular in communities where local news and
information may not be available online or from a single source. Accordingly, we
use local content as a means of attracting and retaining additional end users
and differentiating our service. We are seeking to enter into agreements with
content providers, local advertisers and local e-commerce merchants under which
we will receive a share of revenue from purchases of goods and services by our
customers. Our ability to provide and earn revenues from content is subject to
our agreements with Vulcan Ventures. See "Risk Factors" and "Certain
Transactions."
 
     Future Services. Our high speed access services may allow end users to take
advantage of numerous other applications and services in the future. Additional
future residential services could include Internet telephony services, video
conferencing, various multimedia applications (such as video conferencing, high-
quality audio and distance learning), home alarm, child care and utility
monitoring, e-commerce applications (such as retailing, financial services and
online software distribution), set-top boxes and interactive video games. Among
our planned commercial services are Internet telephony, video conferencing and
gateway telephony. Additionally, our high bandwidth capability may allow us to
offer other business services when new technologies emerge. Prices for these
additional services will depend upon market conditions and we will negotiate
future revenue sharing arrangements with our cable partners. Our ability to

CABLE PARTNERS AND STRATEGIC ALLIANCES
 
     We began offering cable-based Internet services in late 1997 in Maysville,
Kentucky and St. Mary's County, Maryland. We market our services to
approximately 210,000 homes passed, are implementing services to approximately
276,000 additional homes passed and have contracts and letters of intent
covering an additional 611,000 homes passed to which we expect to provide
service in the future. Many of these letters of intent by their terms have
expired, but negotiations for definitive agreements have continued. Our network
services agreements generally provide for a five-year exclusive term from the
date we commence full operation within the cable system.
 
     The following table summarizes our cable partners, the number of homes
passed and the areas served by each cable partner's systems as of March 5, 1999:

     We have approximately 2,800 high speed cable modem end users and
approximately 2,500 dial-up end users.
 
     Cisco Systems, Inc. Cisco, one of our major equipment suppliers, has agreed
to purchase $5 million of our common stock at the initial public offering price,
net of the underwriting discount, concurrently with this offering.
 
     Vulcan Ventures. Vulcan Ventures, which owns Charter, beneficially owns
54.2% of our common stock before the offering. Charter is the seventh largest
cable system operator in the United States. Charter has already committed to us
approximately 765,000 homes passed. We have granted Vulcan warrants to purchase
up to 5 million shares of our common stock for $5.00 per share. These warrants
become exercisable at the rate of one warrant per home passed committed to us by
Charter in excess of 750,000.
 
END USER SALES AND MARKETING
 
     After entering into a network services agreement with a cable operator, we
begin efforts to raise customer awareness and interest in our services. Our
promotional efforts typically include direct mail of standardized marketing
materials, local television and radio advertising, and a public relations and
media campaign. Our cable partners often participate in our promotional efforts.
For example, a cable operator may provide air time for our advertisements or
include our marketing materials in its customer bills. Our selling efforts for
residential end users focus largely on inbound and outbound telemarketing.
Telemarketing may either be conducted in-house or outsourced. We also focus on
local events, such as public on-site demonstrations in shopping malls and
computer stores, as well as demonstrations for educational and civic
organizations. We design some of our programs to create "word of mouth" interest
in our services. For example, we provide free broadband access to elementary and
secondary schools in our service areas. We also generally contract the
installation of cable modems at the end user site to local computer stores,
which we believe also increases community awareness of our services. We conduct
our promotional efforts either at the corporate level or through a local manager
and sales staff maintained in each geographic area in which we operate.
 
     In contrast to our residential sales philosophy, we believe commercial
selling is established through personal relationships with the potential
commercial account, together with personal demonstrations of our services.
Commercial selling is conducted largely through our local manager and sales
staff. Moreover, after the installation and initial promotion of our services
are complete, commercial sales becomes the primary ongoing responsibility of our
local manager and sales staff.

</TABLE>
 
NETWORK OPERATIONS
 
     Our network strategy is to provide a flexible, scalable design that allows
us to optimize performance to the end user while allowing us to achieve
operating cost efficiencies. We provide high speed access by first connecting
our end users through our cable headend to the cable or telephone
infrastructure. We then connect through high speed data lines provided by local
exchange carriers to backbone facilities provided by UUNet (a subsidiary of MCI
Worldcom) and others, which connect our systems to the Internet.
 
     Key elements of our network architecture include:
 
     Network Operations Center. Our network operations center staff monitors our
entire data network 24 hours a day, from the cable modem in a home or business,
all the way through our backbone connection to the Internet. Continuous
surveillance of our data network assists in fault identification and correction
as well as capacity management and optimization. We continuously troubleshoot
and monitor for problems over the cable infrastructure that could cause an
interruption of cable service or Internet access. Our primary network operations
center is located in Louisville, Kentucky, in a secure building with redundant
Internet access equipment and backup power supplies. We plan to construct a
second network operations center. Located in the network operations center is
our data center, which contains servers that provide critical customer services
such as our e-mail, news groups and web hosting servers. We monitor these
redundant servers continuously. We plan to construct regional data centers as
our end user count and geographical clustering increases. In some cases we also
host web pages and e-mail at the headend in order to enhance network
performance.
 
     Backbone and Internet Connections. We have designed a scalable network
architecture that takes advantage of the existing high speed data backbone
operated by UUNet and other well established Internet access providers.
Management believes that it is more advantageous at this time to provision data
backbone services from well established national suppliers than to lease and
manage a new private
 
                                       41
<PAGE>   48
 
network. Our current backbone network is fully redundant and fully meshed, and
utilizes high speed routers supporting speeds of up to 622 Mbps. We typically
lease telecommunications links between the cable headends and our backbone
connection from the regional Bell operating companies. We plan to periodically
use satellite technology to provide temporary connections from the cable headend
to the backbone during the implementation of our service.
 
     Cable Headends. We install servers, routers, switches and other network
devices in each cable headend. This equipment is capable of operating even if
connections with the data center or network operations center are lost. Our
major suppliers of cable headend equipment include Cisco, Sun Microsystems,
Com21, Lucent and Terayon.
 
     To improve the speed of the local network and to balance demands on the
backbone facilities, we utilize caching technologies in the cable headend and in
our data center. We also plan to utilize satellite technology to supplement our
caching efforts. Caching allows us to store popular web content enabling an end
user to access this content more quickly. By using caching technology to move
content closer to the end user, we are able to control our telecommunications
costs and increase the speed of delivery because we refresh this content
periodically, rather than each time an end user seeks access to the content.
 
     Cable Modems and Television Set-Top Boxes. We currently provide a custom
installation CD that allows a cable modem user to install a web browser along
with a selection of popular utility programs. We currently use cable modems
manufactured by Com21 and Terayon, which we either sell or rent to the end user.
The North American cable industry has adopted a set of interface specifications,
known as "DOCSIS," for hardware and software to support cable-based data
delivery using cable modems. We expect that DOCSIS specifications will
facilitate the retail availability of lower cost cable modems, which has three
effects. First, it will save us the cost of purchasing and installing cable
modems for end users. Second, we expect that increased availability of lower
cost cable modems will result in increased demand for our services. Third, we
would also expect a loss of revenue from cable modem rentals. We also expect
computer manufacturers to begin integrating DOCSIS cable modems into their
products. We intend to deploy DOCSIS compliant modems and modem controllers,
when DOCSIS becomes available. In the future, residential end users also may be
able to connect to the Internet via an integrated television set-top box.
 
CUSTOMER SERVICE AND BILLING
 
     Customer Service.  We operate a toll free help desk 24-hours-a-day,
7-days-a-week to provide customer service. The help desk assists end users with
high speed modem questions and problems, as well as basic computer and software
configuration questions and billing inquiries. We also operate and staff a
24-hours-a-day customer service center in our Network Operation Center to handle
problems referred by the help desk. We plan to deploy regional technical and
operating staff to assist our end users and cable partners. Computerized trouble
tickets are opened on all customer service issues, which we track to assure
resolution of all customer service calls received. We also rent cable modems to
our customers and arrange for their installation. Currently we charge end users
up to $150 to install the cable modem, however, we frequently waive this fee. We
typically rent cable modems to the end user for $9.95 per month.
 
     Billing.  We typically prepare and mail the bill for our services, which we
send to the end user under our cable partner's name and logo. Where we have
billing responsibilities we manage cash and credit card payments and remit a
portion of the amount collected to our cable partners, along with a detailed
accounting. We are installing a new billing system to further enhance our
services.
 
COMPETITION
 
     We face competition in two primary areas: (i) competition for partnerships
with cable operators from other cable modem-based providers of Internet access
services and (ii) competition for end users from providers of other types of
data and Internet services. For a discussion of these competitive factors see
"Risk Factors -- The market for Internet services is highly competitive."

GOVERNMENT REGULATION
 
     Although our services are not currently subject to regulation by the
Federal Communications Commission or any other federal or state regulatory
agency, changes in the regulatory environment affecting businesses that provide
Internet connection and content on the Internet could affect the nature, scope,
prices and ability to market our services successfully. For a discussion of
these potential changes in the regulatory environment, see "Risk Factors -- We
may become subject to burdensome government regulation."
 
EMPLOYEES
 
     As of March 5, 1999, we employed 156 people. None of our employees is
subject to any collective-bargaining arrangements, and we consider our relations
with employees to be good.
 
FACILITIES
 
     Our principal executive office is located in Denver, Colorado, where we
lease approximately 13,000 square feet. Our principal operating office is in
Louisville, Kentucky, where we lease approximately 25,000 square feet. We
believe that our existing facilities are adequate for current requirements and
that additional space can be obtained on commercially reasonable terms to meet
future requirements.
 
LEGAL PROCEEDINGS
 
     We are not a party to any material legal proceedings.

  STOCK OPTION PLANS
 
     1998 Stock Option Plan
 
     We adopted the 1998 Stock Option Plan in April 1998 and authorized options
to purchase up to 900,000 shares of common stock for issuance under the plan.
Options to purchase 541,500 shares of common stock have been granted under the
plan, at a weighted average exercise price of $2.59 per share, all of which will
become exercisable upon consummation of the offering. The plan provides for
grants of incentive stock options and nonqualified stock options to our
designated employees and directors. In January 1999, the Board elected not to
grant additional options under the plan.
 
                                       48
<PAGE>   55
 
     Administration of the Plan.  The compensation committee of the board of
directors administers and interprets the plan. The compensation committee:
 
     - Determines the individuals to whom grants are made under the plan;
 
     - Determines the type, size and terms of the grants made to each such
       individual;
 
     - Determines the time when the grants are made and the duration of any
       applicable exercise period; and
 
     - Deals with any other matters arising under the plan.
 
     Grants.  Grants under the plan consist of:
 
     - Options intended to qualify as incentive stock options within the meaning
       of Section 422 of the Internal Revenue Code; and
 
     - Nonqualified stock options not intended to so qualify.
 
     The exercise price of shares of common stock underlying options granted
under the plan is determined by the compensation committee and is equal to or
greater than the fair market value of a share of common stock on the date of
grant, as determined by the compensation committee.
 
     A participant may pay the exercise price of shares of common stock
underlying options granted:
 
     (1) in cash;
 
     (2) with the approval of the compensation committee, by delivering shares
of common stock owned by the grantee; or
 
     (3) by such other method as the compensation committee approves, including
payment through a broker in accordance with specified procedures.
 
     Options vest according to the terms and conditions determined by the
compensation committee and specified in the grant instrument, but in no case at
a rate less than 20% per year over five years from the grant date, subject to
acceleration in certain events, including an initial public offering. The term
of all options granted under the plan does not exceed ten years from the date of
grant.
 
     Change of Control.  Upon a change of control, all outstanding options under
the plan immediately vest. Upon a change of control where we are not the
surviving entity or where we survive only as a subsidiary of another entity, all
outstanding options will be assumed by or replaced with comparable options or
stock by the surviving corporation. A "change of control" is defined to have
occurred:
 
     (1) if any "person", other than persons who are our shareholders as of the
effective date of the plan, acquires all of the then outstanding shares of
common stock;
 
     (2) if we merge or consolidate with another corporation and Broadband
Solutions, LLC will not beneficially own, immediately after the transaction,
shares of the surviving corporation; or
 
     (3) upon the closing of the sale of our common stock in an underwritten
public offering, including this offering.
 
     Section 162(m).  Under Section 162(m) of the Internal Revenue Code, we may
be precluded from claiming a federal income tax deduction for total remuneration
in excess of $1.0 million paid to the chief executive officer or to any of the
other four most highly compensated officers in any one year. Total remuneration
generally would include amounts received upon the exercise of stock options
granted under the plan. An exception exists, however, for amounts received upon
exercise of stock options pursuant to certain grandfathered plans. Options
granted under the plan satisfy this exception.

<PAGE>   56
 
     1999 Stock Option Plan
 
     We adopted the 1999 Stock Option Plan in January 1999. The plan provides
for grants of incentive stock options and nonqualified stock options to our
designated employees, officers and directors.
 
     General. The plan authorizes options to purchase up to 2,000,000 shares of
common stock for issuance. No more than 300,000 shares in the aggregate may be
granted to any individual in any calendar year. If options granted under the
plan expire or are terminated for any reason without being exercised, the shares
of common stock underlying such grant will again be available for purposes of
the plan.
 
     Administration of the Plan.  The compensation committee of the board of
directors administers and interprets the plan. The compensation committee will
consist of two or more persons appointed by the board of directors from among
its members, each of whom must be a "non-employee director" as defined by Rule
16b-3 under the Securities Exchange Act of 1934, and an "outside director" as
defined by Section 162(m) of the Internal Revenue Code. The compensation
committee has the sole authority to:
 
     - Determine the employees to whom grants will be made under the plan;
 
     - Determine the type, size and terms of the grants to be made to each such
       employee;
 
     - Determine the time when the grants will be made and the duration of any
       applicable exercise or restriction period, including the criteria for
       vesting; and
 
     - Deal with any other matters arising under the plan.
 
     Grants.  Grants under the plan may consist of:
 
     - Options intended to qualify as incentive stock options within the meaning
       of Section 422 of the Internal Revenue Code; and
 
     - Nonqualified stock options that are not intended to so qualify.
 
     Eligibility for Participation. Grants may be made to any of our employees,
officers and directors. As of March 5, 1999, we had granted options to purchase
30,000 shares at an exercise price of $5.00 per share and 31,000 shares at an
exercise price equal to the initial public offering price per share.
 
     Options. Incentive stock options and non-qualified stock options may be
granted to our employees. The exercise price of common stock underlying an
option will be determined by the compensation committee, and may be equal to,
greater than, or less than the fair market value of a share of common stock on
the date of grant, provided that
 
     (a) the exercise price of an incentive stock option shall be equal to or
greater than the fair market value of a share of common stock on the date such
incentive stock option is granted, and
 
     (b) the exercise price of an incentive stock option granted to an employee
who owns more than 10% of the common stock may not be less than 110% of the fair
market value of the underlying shares of common stock on the date of grant.
 
     The participant may pay the exercise price:
 
     (1) in cash;
 
     (2) with the approval of the compensation committee, by delivering shares
of common stock owned by the grantee; or
 
     (3) by such other method as the compensation committee approves, including
payment through a broker in accordance with specified procedures.
 
     All options granted under the plan vest at a rate of 20% per year over five
years from the grant date.
 
     The compensation committee will determine the term of each option up to a
maximum of ten years from the date of grant, except that the term of an
incentive stock option granted to an employee who owns more than 10% of the
common stock may not exceed five years from the date of grant.
                                       50
<PAGE>   57
 
     Change of Control. Upon a change of control, where the surviving or
acquiring entity does not assume all outstanding options or replace them with
comparable options, the compensation committee may accelerate the vesting of all
outstanding options so that they become exercisable as of the participant's next
vesting date at such times and on such conditions as the compensation committee
determines.
 
     A change of control is defined to have occurred in the event of:
 
     (1) a dissolution or liquidation of the company;
 
     (2) a merger or consolidation in which we are not the surviving corporation
unless there is no substantial change in the stockholders of the company and
outstanding options are assumed by the successor corporation;
 
     (3) a merger in which we are the surviving company but our stockholders
cease to own any shares in the company;
 
     (4) the sale of substantially all the assets of the company; or
 
     (5) the acquisition, sale or transfer of more than 50% of our outstanding
shares by tender offer or similar transaction (except for acquisitions of more
than 50% of our outstanding shares by Vulcan Ventures or an affiliate).
 
     Amendment and Termination of the Plan. The compensation committee may amend
or terminate the plan at any time; except that it may not make any amendment
that requires stockholder approval pursuant to Rule 16b-3 of the Securities
Exchange Act of 1934 or Sections 162(m) or 422 of the Internal Revenue Code
without stockholder approval. The plan will terminate on the tenth anniversary
of its effective date, unless the compensation committee terminates the plan
earlier or extends it with approval of the stockholders.
 
     Section 162(m). Under Section 162(m) of the Internal Revenue Code, we may
be precluded from claiming a federal income tax deduction for total remuneration
in excess of $1.0 million paid to the chief executive officer or to any of the
other four most highly compensated officers in any one year. Total remuneration
would include amounts received upon the exercise of stock options granted under
the plan. An exception exists, however, for "performance-based compensation,"
including amounts received upon the exercise of stock options pursuant to a plan
approved by stockholders that meets certain requirements. The plan has been
approved by stockholders and is intended to make grants of options thereunder
meet the requirements of "performance-based compensation."
 
1999 NON-EMPLOYEE DIRECTORS PLAN
 
     We adopted the 1999 Non-Employee Directors Plan in January 1999. As of
March 5, 1999, options to purchase 122,500 shares at an exercise price of $5.00
per share were outstanding under the plan. Under the plan, each non-employee
director is automatically granted an option to purchase 17,500 shares of common
stock on the effective date of the plan, or the date on which the person first
becomes a non-employee director. Subsequent grants of options to purchase 7,500
shares of common stock are made to each non-employee director on the first
business day of each subsequent year, provided the director has served on the
board for at least the prior six months. Additional options may be granted under
the plan from time to time by the compensation committee to reward extraordinary
services by a director, subject to the consent of the remaining directors.
 
     The plan authorizes up to 300,000 shares of common stock for issuance. If
options granted under the plan expire or are terminated for any reason without
being exercised, the shares of common stock underlying the grant will again be
available for purposes of the plan.
 
     The compensation committee of the board of directors administers and
interprets the plan. The exercise price of options granted under the plan will
be equal to the fair market value of a share of common stock on the date the
option is granted. Each director's initial grant of options under the plan vests
immediately upon grant. Subsequent options granted to a director under the plan
will vest ratably
 
                                       51
<PAGE>   58
 
over the director's then current term of service. Initial options and each
subsequent option granted will have a term of ten years.

                              CERTAIN TRANSACTIONS
 
     Ron Pitcock, Sr. and W. Kent Oyler, III, both executive officers of HSA,
David Gibbs, a former executive officer of HSA, and Joseph S. Gans, III, a
former director of HSA, were involved in our founding and organization. At its
formation in March 1997, CATV.net, Inc., a subsidiary of HSA following our
formation in 1998, issued an aggregate of 1 million shares of common stock to
OPM Services, Inc. and Colorado Limited Partnership, affiliates of Mr. Oyler,
and 1 million shares of common stock to the Gibbs Family Limited Partnership, an
affiliate of Mr. Gibbs. High Speed Access Network, Inc., a subsidiary of HSA
following our formation in 1998, issued 980,000 shares of common stock to the
Pitcock Family Limited Partnership, an affiliate of Mr. Pitcock, and 816,000
shares of common stock to Mr. Gans. The shares of common stock of CATV.net
issued to Mr. Oyler and Mr. Gibbs and the shares of common stock of High Speed
Access Network issued to Mr. Pitcock and Mr. Gans were exchanged for shares of
our common stock in April 1998. Mr. Pitcock, Mr. Oyler, Mr. Gibbs and Mr. Gans
each contributed a nominal amount of capital for our initial capitalization. Mr.
Gibbs and Mr. Oyler are entitled to certain registration rights with respect to
their shares of common stock. See "Description of Capital Stock--Registration
Rights".
 
     Since our formation and prior to the completion of this offering, we will
have issued 20 million shares of convertible preferred stock, which will
automatically convert into an aggregate of 20 million shares of common stock
upon or immediately prior to the completion of this offering. No dividends have
been declared or paid on the convertible preferred stock; however, the
cumulative, accrued and unpaid dividends on the convertible preferred stock will
be paid in shares of common stock upon conversion of the preferred stock. If we
complete this offering on             , 1999, we will issue           shares of
common stock in payment of the accrued and unpaid dividends on the convertible
preferred stock. The holders of common stock issued upon conversion of the
convertible preferred stock are entitled to registration rights. See
"Description of Capital Stock--Registration Rights".
 
     Broadband Solutions, LLC owns 3,905,000 shares of Series A convertible
preferred stock and River Cities Capital Fund Limited Partnership owns 1,095,000
shares of Series A convertible preferred stock. The purchase price of $1.00 per
share for the Series A convertible preferred stock was paid in cash. Broadband
Solutions II, LLC owns 1,562,000 shares of Series B convertible preferred stock
and River Cities Capital Fund Limited Partnership owns 438,000 shares of Series
B convertible preferred stock. The purchase price of the Series B convertible
preferred stock of $2.50 per share was paid in cash and/or in exchange for a
note owing to Broadband. David A. Jones, Jr., our Chairman of the Board, is the
managing director, and Robert S. Saunders, our Vice Chairman, Irving W. Bailey,
II and Michael E. Gellert, directors, are managers, of Broadband Solutions, LLC
and Broadband Solutions II, LLC. In addition, entities controlled by Messrs.
Jones, Saunders, Bailey and Gellert, respectively, are members of Broadband
Solutions, LLC and Broadband Solutions II, LLC. In connection with the sale of
the Series A convertible preferred stock to Broadband Solutions, LLC, we agreed
to pay Chrysalis Ventures a consulting fee of $20,000 per quarter, upon approval
by the board of directors. Mr. Jones and Mr. Saunders are Chairman and Senior
Managing Director, respectively, of Chrysalis Ventures. In 1998, we accrued
$60,000 payable to Chrysalis Ventures under this agreement.
 
     In November 1998, we entered into a systems access and investment agreement
with Vulcan Ventures and Charter Communications, a programming content agreement
with Vulcan, and a related network services agreement with Charter. Under these
agreements, Charter committed to provide us exclusive access to at least 750,000
homes passed. Vulcan has an equity incentive to cause Charter to provide us
additional homes passed, although neither Vulcan nor Charter is obligated to do
so. Charter can terminate our exclusivity rights for any other reason, on a
system-by-system basis, if we fail to meet performance benchmarks or otherwise
breach our agreement, including our agreement to support content provided by
Vulcan. Charter can terminate our agreement for any other reason as long as it
purchases the associated cable head end equipment and modems at book value and
pays us a termination fee based on the net present value of the revenues we
otherwise would earn for the remaining term of the agreement from end users
subscribing to our services as of the termination date. During the term of the
agreements, we have agreed not to deploy Worldgate(SM), Web TV(R), digital TV or
related products
                                       53
<PAGE>   60
 
in the market areas of any committed system or in any area which Charter
operates a cable system. The agreements will continue until we cease to provide
services to an end user residing in a home passed in a committed system.
 
     Concurrently with our entering into these agreements, we issued 8 million
shares of Series B convertible preferred stock to Vulcan at a purchase price of
$2.50 per share, which it acquired for cash. Vulcan also subscribed to purchase
2.5 million shares of our Series C convertible preferred stock at a purchase
price of $5.00 per share on or before November 25, 2000, and received an option
to purchase an additional 2.5 million shares of our Series C convertible
preferred stock at a purchase price of $5.00 per share on or before November 25,
2000. Vulcan has agreed to purchase prior to or concurrently with the offering
the entire 5 million shares of Series C convertible preferred stock, which will
automatically convert at a price of $5.00 per share into common stock upon
completion of this offering. Vulcan is entitled to registration rights with
respect to the shares of Series B and Series C convertible preferred stock
issued to it. See "Description of Capital Stock--Registration Rights."
 
     As an inducement to Vulcan to cause Charter to commit additional systems to
us, we granted Vulcan warrants to purchase up to 5 million shares of our common
stock at a purchase price of $5.00 per share. The warrants are earned by Vulcan
at the rate of one share of common stock for each home passed committed to us by
Charter in excess of 750,000. 2.5 million warrants may be earned by Vulcan on or
before July 31, 2001, and 2.5 million warrants may be earned by Vulcan on or
before July 31, 2003. Each warrant issued to Vulcan must be exercised on or
before one year from the completion of this offering. The warrants may be
forfeited in certain circumstances, generally if the number of homes passed in a
committed system is reduced. All shares of common stock issuable upon exercise
of the warrants have registration rights. See "Description of Capital
Stock -- Registration Rights".
 
     In February 1998, CATV.net, Inc. and OPM Services, Inc., an entity
controlled by W. Kent Oyler, III, our Chief Operating Officer, entered into a
services agreement under which OPM agreed to provide, on CATV's behalf, certain
financial, accounting, professional staffing and legal services. During 1998,
OPM received fees of $71,160 under the agreement. The agreement was terminated
on December 31, 1998.
 
     In October 1997, HSA and Gans Multimedia Partnership, an entity owned by
Joseph S. Gans, III, a founder and former director of HSA, entered into a cable
affiliate agreement under which Gans Multimedia granted us the exclusive right
to provide the customers of two cable systems owned by Gans Multimedia with high
speed Internet access. The agreement has a five year term and provides that Gans
Multimedia will receive 25% of the gross revenues we receive under the
agreement. During 1998, we paid Gans Multimedia $76,116 under the agreement.
 
     In April 1998, we borrowed $650,000 from Gans Multimedia. The note bears
interest at the rate of 7% per annum. We repaid $150,000 of the principal in
December 1998 and the remaining $500,000 balance matures on April 1, 2001. The
loan is secured by various operating assets we own in St. Mary's County,
Maryland.
 
     In October 1998, Broadband Solutions II, LLC lent us $1 million, pursuant
to a 12% promissory note. Broadband exchanged the note for 400,000 shares of our
Series B convertible preferred stock and $10,750 in cash, representing accrued
and unpaid interest under the note, in November 1998.
 
     In March 1999, we plan to transfer to Darwin Networks, Inc., a newly
created Delaware corporation, all of the assets used in our digital subscriber
line technology division in exchange for 100% of the outstanding Darwin common
stock. Prior to completion of the offering, we will distribute all of the
outstanding Darwin common stock to our shareholders on a pro rata basis. In
connection with the transaction we plan to enter into a services agreement with
Darwin pursuant to which we will provide various financial, accounting and other
professional staff services to Darwin and will be compensated for our costs at
fair market value. We also will enter into a sublease pursuant to which Darwin
will lease space in our Louisville, Kentucky offices at fair market value. The
services agreement and sublease will be for an initial six month term. After we
complete the distribution, we will lend Darwin up to
 
                                       54
<PAGE>   61
 
$500,000 for working capital pursuant to a six month unsecured revolving credit
note bearing interest at the prime rate. At that time, in connection with the
note, Darwin will issue us a warrant to purchase 1 million shares of Darwin
common stock at an exercise price of $5.00 per share. David F. Gibbs, a current
stockholder and former officer of HSA, will be an executive officer of Darwin.

                           DESCRIPTION OF SECURITIES
 
     At the closing of the offering our authorized capital stock will consist of
          shares of common stock, par value $.01 per share, and 10 million
shares of preferred stock, par value $.01 per share. We are a Delaware
corporation, subject to the Delaware General Corporation Law.
 
COMMON STOCK
 
     Holders of our common stock are entitled to receive, as, when and if
declared by the board of directors from time to time, such dividends and other
distributions in cash, stock or property from our assets or funds legally
available for such purposes subject to the rights of any preferred stock that
may be authorized. Holders of common stock are entitled to one vote for each
share held of record on all matters on which shareholders may vote.
 
     There are no preemptive, conversion, redemption or sinking fund provisions
applicable to the common stock. All outstanding shares of common stock are fully
paid and nonassessable. In the event of our liquidation, dissolution or winding
up, holders of common stock are entitled to share ratably in the assets
available for distribution, subject to the rights of any preferred stock that
may be authorized.
 
PREFERRED STOCK
 
     Our board of directors, without further action by the stockholder, is
authorized to issue an aggregate of 10,000,000 shares of preferred stock. Upon
completion of this offering, no shares of preferred stock will be outstanding
and we have no plans to issue a new series of preferred stock. Our board of
directors may, without stockholder approval, issue preferred stock with dividend
rates, redemption prices, preferences on liquidation or dissolution, conversion
rights, voting rights and any other preferences, which rights and preferences
could adversely affect the voting power of the holders of common stock.
Issuances of preferred stock, while providing desirable flexibility in
connection with possible acquisitions or other corporate purposes, could have
the effect of making it more difficult for a third party to acquire, or could
discourage or delay a third party from acquiring, a majority of our outstanding
stock.
 
OPTIONS
 
     Options to purchase a total of 2 million shares of common stock may be
granted under the 1999 stock option plan and options to purchase 300,000 shares
of common stock may be granted under the 1999 non-employee directors stock
option plan. There are outstanding options to purchase a total of 183,500 shares
of common stock under these plans and 541,500 shares of common stock under the
1998 stock option plan. Of the total options outstanding, options to purchase
664,000 shares will be exercisable upon the closing of this offering. Any shares
issued upon exercise of these options will be immediately available for sale in
the public market upon our filing of a registration statement after the offering
relating to our stock option plans and the terms of lock-up agreements entered
into between our optionholders and the underwriters. See "Management--Stock
Option Plans" and "Shares Eligible for Future Sale."
 
WARRANTS
 
     We are a party to certain warrant agreements that will under certain
circumstances entitle Vulcan to purchase 5 million shares of common stock at a
purchase price of $5.00 per share. The warrants are exercisable on the basis of
one share of common stock for each home passed in a Charter cable system in
excess of 750,000 homes passed with respect to which we are retained to provide
high speed Internet access services. The warrants will be forfeited as to 2.5
million shares if they do not become exercisable on or before July 31, 2001, and
as to 2.5 million shares if they do not become exercisable on or before July 31,
2003. The warrants may be forfeited in certain other circumstances, generally,
if the number of homes passed is reduced. As of March 5, 1999, Vulcan had earned
warrants to purchase 14,820 shares. The exercise price and the number of shares
of common stock that may be issued under the warrants are subject to adjustment
upon the occurrence of certain events, including certain issuances of capital
stock, rights, options, warrants or other securities;
 
                                       59
<PAGE>   66
 
stock splits; stock dividends; reorganizations; reclassifications;
consolidations or mergers. All shares of common stock issuable upon exercise of
all warrants have certain registration rights. See "Description of Capital
Stock--Registration Rights".
 
OTHER EQUITY-BASED AGREEMENTS
 
     From time to time in connection with the negotiation of material
agreements, we may use equity-based arrangements, including warrants to purchase
shares of common stock, as an incentive for a strategic partner to enter into an
agreement with us.
 
REGISTRATION RIGHTS
 
     We entered into registration rights agreements with certain of our
stockholders. After the completion of this offering, the holders of 20 million
shares of common stock issuable upon the conversion of all of the outstanding
preferred stock, and warrants to purchase an additional 5 million shares of
common stock, will be entitled to certain demand registration rights with
respect to the registration of their registrable securities under the Securities
Act. The holders of 25% or more of the registrable securities are entitled to
demand that we register their registrable securities under the Securities Act.
We are not required to effect more than two registrations pursuant to these
demand registration rights. In addition, these holders are entitled to require
us to include their registrable securities in future registration statements
that we may file. In addition, OPM Services, Inc. and Colorado Limited
Partnership, affiliates of W. Kent Oyler, III, and the Gibbs Family Limited
Partnership, an affiliate of David Gibbs, may demand that we register up to 20%
of their 2 million shares of common stock under the Securities Act. We are not
required to effect more than one registration pursuant to this demand
registration right. In addition, these holders may require us to include their
shares in future registration statements that we may file. These registration
rights are subject to various conditions and limitations, including the right of
the underwriters of an offering to limit the number of registrable securities
that may be included in the offering. In addition, holders of all of these
shares will be restricted from exercising their demand rights until 180 days
after the date of this prospectus. We are generally required to bear all of the
expenses of these registrations, except underwriting discounts and selling
commissions. Registration of any of the registrable securities held by security
holders with registration rights will result in shares becoming freely tradable
without restriction under the Securities Act immediately upon the effectiveness
of such registration.
 
DELAWARE BUSINESS COMBINATION STATUTE
 
     Section 203 of the Delaware General Corporation Law generally prohibits a
publicly-held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years after the date of
the transaction in which the person became an interested stockholder, unless the
interested stockholder attained such status with the approval of the board of
directors or unless the business combination is approved in a prescribed manner.
A "business combination" includes mergers, asset sales and other transactions
resulting in a financial benefit to the interested stockholder. Subject to
certain exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, fifteen percent
(15%) or more of the corporation's voting stock. This statute could prohibit or
delay a change in control of our company and could discourage potential
acquisition proposals.
 
BOARD OF DIRECTORS VACANCIES
 
     Our bylaws authorize the board of directors to fill vacant directorships or
increase the size of the board of directors. This may deter a stockholder from
attempting to remove incumbent directors and simultaneously gaining control of
our board of directors by filling the vacancies created with its own nominees.
 
                                       60
<PAGE>   67
 
STOCKHOLDER ACTION BY WRITTEN CONSENT; SPECIAL MEETINGS
 
     Our amended and restated certificate of incorporation provides that
stockholders may not take action by written consent, but only at duly called
annual or special meetings of stockholders. The certificate further provides
that special meetings of our stockholders may be called only by the board of
directors, or by our chairman.
 
CLASSIFIED BOARD OF DIRECTORS
 
     Our amended and restated certificate of incorporation divides our board of
directors into three classes, with regular three-year staggered terms and
initial terms of one year for the class I directors, two years for the class II
directors and three years for the class III directors. This could prevent a
party who acquires control of a majority of our outstanding voting stock from
obtaining control of the board of directors.
 
     Our stockholders do not have the right to cumulative voting in the election
of directors.
 
ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS
 
     Our bylaws provide that stockholders seeking to bring business before an
annual meeting of stockholders, or to nominate candidates for election as
directors at an annual meeting of stockholders, must provide advance notice to
us in writing. These provisions may preclude stockholders from bringing matters
before or from making nominations for directors at an annual meeting of
stockholders.
 
AUTHORIZED BUT UNISSUED SHARES
 
     The ability of the board of directors to establish the rights of, and to
issue, substantial amounts of preferred stock without the need for shareholder
approval, may have the effect of discouraging, delaying or preventing a change
in control. Such preferred stock, among other things, may be used to create
voting impediments with respect to any changes in control or to dilute the stock
ownership of holders of common stock seeking to obtain control.
 
AMENDMENTS TO OUR CERTIFICATE AND BYLAWS
 
     Under Delaware law, the affirmative vote of a majority of the shares
entitled to vote on any matter is required to amend a corporation's certificate
of incorporation or bylaws.
 
LIMITATION OF LIABILITY
 
     Our amended and restated certificate of incorporation provides that none of
our directors will be personally liable to us or our stockholders for monetary
damages for any breach of fiduciary duty as a director except for liability for
breach of the director's duty of loyalty, for acts or omissions which are not in
good faith or which involve intentional misconduct or knowing violations of law,
for actions leading to improper personal benefit to the director, and for the
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by Delaware law. This provision does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws.
 
     We have entered into agreements to indemnify our directors, in addition to
the indemnification provided for in our certificate of incorporation. We believe
that these provisions and agreements are necessary to attract and retain
qualified directors and executive officers. We maintain liability insurance to
provide directors and officers with insurance coverage for losses arising from
claims based on breaches of duty, negligence, error and other wrongful acts.
 
     At present, there is no pending litigation or proceeding, and we are not
aware of any threatened litigation or proceeding, that may result in a claim for
such indemnification involving any director, officer, employee or agent as to
which indemnification will be required or permitted under the certificate of
incorporation.
 
                                       61
<PAGE>   68
 
INDEMNIFICATION
 
     Section 145 of the Delaware corporate laws provide for the power to
indemnify any directors and officers and to purchase insurance with respect to
liability arising out of their capacity or status as directors and officers. The
indemnification provisions are not exclusive of any other rights to which the
directors and officers may be entitled under the corporation's bylaws, any
agreement, a vote of stockholders or otherwise.
 
     Our amended and restated certificate of incorporation provides a right to
indemnification to the maximum extent permitted by Delaware law to any person
who was or is a party or is threatened to be made a party to or becomes involved
in any action, suit or proceeding (whether civil, criminal, administrative or
investigative) by reason of the fact that such person is or was our director or
officer, or is or was serving at our request as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement reasonably incurred by such
person in connection with such action, suit or proceeding. The certificate of
incorporation provides for the advancement of expenses incurred by any of our
directors, officers or other employees in the defense of any such actions, suits
or proceedings, so long as any director, officer or employee engaged in such a
defense is not later found ineligible for indemnification. The certificate of
incorporation also permits us to secure insurance on behalf of any officer,
director, employee or other agent for any liability arising out of his or her
actions, regardless of whether Delaware law would permit indemnification.

                        UNITED STATES FEDERAL INCOME TAX
                        CONSEQUENCES TO NON-U.S. HOLDERS
 
     The following is a general discussion of certain U.S. federal income and
estate tax consequences of the ownership and disposition of common stock
applicable to Non-U.S. Holders of common stock who acquire and own it as a
capital asset within the meaning of section 1221 of the Internal Revenue Code. A
"Non-U.S. Holder" is any person other than (a) a citizen or resident of the
United States, (b) a corporation or partnership created or organized in the
United States or under the laws of the United States or of any state, or (c) an
estate whose income is includable in gross income for United States federal
income tax purposes regardless of its source, or (d) a trust if (i) a court
within the United States is able to exercise primary supervision over the
administration of the trust and (ii) one or more United States persons have the
authority to control all substantial decisions of the trust. For purposes of the
withholding tax on dividends discussed below, a non-resident fiduciary of an
estate or trust will be considered a Non-U.S. Holder. An individual may, subject
to certain exceptions, be deemed to be a resident alien (as opposed to a
non-resident alien) by virtue of being present in the United States on at least
31 days in the calendar and for an aggregate of at least 183 days during a
three-year period in the current calendar year (counting for these purposes all
of the days present in the current year, one-third of the days present in the
immediately preceding year, and one-sixth of the days present in the second
succeeding year). Resident aliens are subject to U.S. federal tax as if they
were U.S. citizens and, thus, are not Non-U.S. Holders for purposes of this
discussion.
 
     This discussion does not consider specific facts and circumstances that may
be relevant to a particular Non-U.S. Holder's tax position (including the fact
that in the case of a Non-U.S. Holder that is a partnership, the U.S. tax
consequences of holding and disposing of shares of common stock may be affected
by certain determinations made at the partner level) and does not consider U.S.
state and local or non-U.S. tax consequences. Further, it does not consider
Non-U.S. Holders subject to special tax treatment under the federal income tax
laws (including banks and insurance companies, dealers in securities, and
holders of securities held as part of a "straddle," "hedge" or "conversion
transaction"). In addition, persons that hold the common stock through "hybrid
entities" may be subject to special rules and may not be entitled to the
benefits of a U.S. income tax treaty. The following discussion is based on
provisions of the Internal Revenue Code and administrative and judicial
interpretations as of the date hereof, all of which are subject to change,
possibly on a retroactive basis, any change could affect the continuing validity
of this discussion. THE FOLLOWING SUMMARY IS INCLUDED HEREIN FOR GENERAL
INFORMATION. ACCORDINGLY, IF YOU ARE A NON-U.S. HOLDER, WE URGE YOU TO CONSULT A
TAX ADVISOR WITH RESPECT TO THE UNITED STATES FEDERAL TAX CONSEQUENCES OF
HOLDING AND DISPOSING OF OUR COMMON STOCK, AS WELL AS ANY TAX CONSEQUENCES THAT
MAY ARISE UNDER THE LAWS OF ANY U.S. STATE, LOCAL OR OTHER NON-U.S. TAXING
JURISDICTION.
 
     Dividends. In general, dividends paid to a Non-U.S. Holder will be subject
to withholding of U.S. federal income tax at a 30% rate unless this rate is
reduced by an applicable income tax treaty. Dividends that are effectively
connected with the holder's conduct of a trade or business in the United States,
or, if a tax treaty applies, attributable to a permanent establishment or in the
case of an individual a "fixed base," in the United States ("U.S. trade or
business income") are generally subject to U.S. federal income tax at regular
rates and are not generally subject to withholding if the Non-U.S. Holder files
the appropriate form with payor. Any U.S. trade or business income received by a
non U.S. corporation may also, under certain circumstances, be subject to an
additional "branch profits tax" at a 30% rate, or any lower rate that may be
applicable under an income tax treaty.
 
     Under current law, dividends paid to an address in a foreign country are
presumed (absent actual knowledge to the contrary) to be paid to a resident of
that country for purposes of the withholding discussed above, and under the
current interpretation of U.S. Treasury regulations, for purposes of determining
the applicability of a tax treaty rate. Under final U.S. Treasury regulations,
effective January 1, 2000; however, a Non-U.S. Holder of common stock who wishes
to claim the benefit of an applicable treaty rate would be required to satisfy
applicable certification and other requirements, which
                                       63
<PAGE>   70
 
would include the requirements that the Non-U.S. Holder file a Form W-8 which
contains the holder's name and address.
 
     A Non-U.S. Holder of common stock that is eligible for a reduced rate of
U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any
excess amounts currently withheld by filing an appropriate claim for a refund
with the U.S. Internal Revenue Service.
 
     Disposition of Common Stock. Except as described below, a Non-U.S. Holder
generally will not be subject to U.S. federal income tax in respect of gain
recognized on a disposition of common stock provided that (i) the gain is not
U.S. trade or business income, (ii) the Non-U.S. Holder is not an individual who
is present in the United States for 183 or more days in the taxable year of the
disposition and who meets certain other requirements, (iii) the Non-U.S. Holder
is not subject to tax pursuant to the provisions of U.S. tax law applicable to
certain United States expatriates, and (iv) the Company has not been and does
not become a "United States real property holding corporation" for U.S. federal
income tax purposes. The Company believes that it has not been, is not
currently, and is not likely to become, a United States real property holding
corporation. However, no assurance can be given that the Company will not be a
United States real property corporation when a Non-U.S. Holder sells its shares
of common stock.
 
     Federal Estate Taxes. In general, an individual who is a Non U.S. Holder
for U.S. estate tax purposes will incur liability for U.S. federal estate tax if
the fair market value of property included in the individual's taxable estate
for U.S. federal estate tax purposes exceeds the statutory threshold amount. For
these purposes, common stock owned, or treated as owned, by an individual who is
a Non-U.S. Holder at the time of death will be included in the individual's
gross estate for U.S. federal tax purposes, unless an applicable estate tax
treaty provides otherwise.
 
     U.S. Information Reporting Requirements and Backup Withholding Tax. We are
required to report annually to the Internal Revenue Service and to each Non-U.S.
Holder the amount of dividends paid to, and the tax withheld with respect to,
each Non-U.S. Holder. These reporting requirements apply regardless of whether
withholding was reduced or eliminated by an applicable tax treaty. Copies of
these information returns may also be made available under the provisions of a
specific treaty or agreement to the tax authorities in the country in which the
Non-U.S. Holder resides. Under current regulations, the United States backup
withholding tax (which generally is a withholding tax imposed at the rate of 31%
on certain payments to persons that fail to furnish the information reporting
requirements) will generally not apply to dividends paid on the common stock to
a Non-U.S. Holder at an address outside the United States. Under final Treasury
regulations, effective January 1, 2000, a Non-U.S. Holder generally would not be
subject to backup withholding at a 31% rate if the beneficial owner certifies to
that owner's foreign status on a valid Form W-8.
 
     Non-U.S. Holders will not be subject to information reporting or backup
withholding with respect to the payment of proceeds from the disposition of
common stock effected by a foreign office of a foreign broker provided however
that if the broker is a U.S. person or a "U.S. related person," information
reporting (but not backup holding) would not apply unless the broker receives a
statement from the owner, signed under penalties of perjury, certifying its
foreign status or otherwise establishing an exemption or the broker has
documentary evidence in its files as to the Non-U.S. Holder's foreign status and
the broker has no actual knowledge to the contrary. For this purpose, a "U.S.
related person" is (i) a "controlled foreign corporation" for U.S. federal
income tax purposes, (ii) a foreign person 50% or more of whose gross income
from all sources for the three-year period ending with the close of its taxable
year preceding the payment (or for the part of the period that the broker has
been in existence) is derived from activities that are effectively connected
with the conduct of a U.S. trade or business, (iii) a foreign partnership that
is either engaged in a U.S. trade or business or in which U.S. persons hold more
than 50% of the income or capital interest, or (iv) certain U.S. branches of
foreign banks or insurance companies.
 
                                       64
<PAGE>   71
 
     Non-U.S. Holders will be subject to information reporting and backup
withholding at a rate of 31% with respect to the payment of proceeds from the
disposition of common stock effected by to or through the United States office
of a broker, U.S. or foreign, unless the Non-U.S. Holder certifies as to its
foreign status under penalties of perjury or otherwise establishes an exemption.
 
     Any amounts withheld under the backup withholding rules from a payment to a
Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder's U.S.
federal income tax, and any amounts withheld in excess of the Non-U.S. Holder's
federal income tax liability will be refunded, provided that the required
information is furnished to the Internal Revenue Service.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of common stock in the public market following
the offering could adversely affect the market price of the common stock and
could impair our ability to raise capital.
 
     Of the           shares of common stock outstanding after the offering
(assuming no exercise of the underwriters' over-allotment option and no exercise
of outstanding options or warrants), the           shares sold in the offering
and the             shares to be sold to Cisco will be freely tradable in the
public market, unless such shares are held by "affiliates" as that term is
defined in Rule 144 under the Securities Act, and subject to the terms of
certain lockup agreements entered into between certain stockholders and the
underwriters. For purposes of Rule 144, an "affiliate" of an issuer is a person
that, directly or indirectly, through one or more intermediaries, controls, or
is controlled by or is under common control with, such issuer. The remaining
24,000,000 shares of common stock are "restricted securities" as defined under
Rule 144. Restricted securities may be sold in the public market only if
registered or upon the expiration of certain holding periods under Rule 144,
subject to the volume, manner of sale and other limitations of Rule 144.
 
     In general, under Rule 144, as currently in effect, a person (or persons
whose shares are required to be aggregated), including an affiliate, who has
beneficially owned shares for at least one year is entitled to sell, within any
three-month period commencing 90 days after the date of the completion of the
offering, a number of shares that does not exceed the greater of (i) 1% of the
then outstanding shares of common stock (approximately           shares
immediately after the offering) or (ii) the average weekly trading volume in the
common stock during the four calendar weeks preceding the date on which notice
of such sale is filed. In addition, a person who is not an affiliate 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 is entitled to sell all those shares
under Rule 144(k) without regard to the volume limitations, manner of sale
provisions or public information requirements. To the extent that shares are
acquired from one of our affiliates in a privately negotiated transaction, the
holding period under Rule 144 of the person acquiring the shares being sold by
our affiliate commences on the date of transfer from the affiliate.
 
     As of the date of this prospectus, options to purchase a total of 725,000
shares of common stock are outstanding under our stock option plans, 664,000 of
which will be exercisable upon completion of the offering and warrants to
purchase a total of 5 million shares of common stock are outstanding, all of
which become exercisable at the rate of one warrant per home passed committed to
us by Charter in excess of 750,000. See "Management--Compensation of Directors"
and "--Stock Option Plans."
 
     We and our directors, officers, substantially all current stockholders
(holding an aggregate of 24 million shares of common stock and warrants to
purchase up to 5 million shares of common stock) and Cisco have agreed not to
offer to sell, sell or otherwise dispose of, directly or indirectly, any shares
of common stock during the 180-day period following the date of the prospectus
without the prior written consent of Lehman Brothers, except that we may issue,
and grant options to purchase, shares of common stock under our option plans. In
addition, we may issue shares of common stock in connection with any acquisition
of another company if the terms of such issuance provide that such common stock
will not be resold prior to the expiration of the 180-day period referenced in
the preceding sentence.
 
     Following the offering, holders of 22 million shares of our outstanding
common stock and holders of warrants to purchase up to 5 million shares of
common stock will have certain demand registration rights with respect to their
shares of common stock (subject to the 180-day lock-up arrangement described
above), under certain circumstances and conditions, to require us to register
their shares of common stock under the Securities Act, and certain rights to
participate in any future registration of securities by us. If those 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 an adverse
effect on the market price for the common stock. Holders of registrable
securities have agreed to be subject to a lock-up period of not more than 180
days following the date of this prospectus. See "Description of
Securities -- Registration Rights."

     The underwriting agreement provides that the underwriters' obligations to
purchase shares of common stock are subject to certain conditions, and that if
any of the foregoing shares of common stock are purchased by the underwriters
pursuant to an underwriting agreement, all of the shares of common stock that
the underwriters have agreed to purchase pursuant to the underwriting agreement
must be so purchased.
 
     The representatives have advised us that the underwriters propose to offer
the shares of common stock directly to the public at the public offering price
set forth on the cover page of this prospectus, and to certain selected dealers,
who may include the underwriters, at such public offering price less a selling
concession not in excess of $     per share. The underwriters may allow, and the
selected dealers may reallow, a concession not in excess of $     per share to
certain brokers and dealers. After the offering, the underwriters may change the
offering price and other selling terms.
 
     The following table summarizes the compensation and estimated expenses we
will pay.

     We have granted to the underwriters an option to purchase up to an
aggregate of                     additional shares of common stock, exercisable
solely to cover over-allotments, if any, at the public offering price less the
underwriting discounts and commissions shown on the cover page of this
prospectus. Such option may be exercised at any time, and from time to time,
until 30 days after the date of the underwriting agreement. To the extent that
the underwriters exercise this option, each underwriter will be committed,
subject to certain conditions, to purchase a number of additional shares of
common stock
 
                                       67
<PAGE>   74
 
proportionate to such underwriter's initial commitment, as indicated in the
preceding table, and we will be obligated, under such over-allotment option, to
sell such shares of common stock to the underwriters.
 
     We and our directors, officers, and substantially all current stockholders,
(holding an aggregate of 22,000,000 shares of common stock and warrants to
purchase 14,820 shares of common stock), and Cisco have agreed not to offer to
sell, sell or otherwise dispose of, directly or indirectly, any shares of common
stock during the 180-day period following the date of the prospectus without the
prior written consent of Lehman Brothers, except that we may issue, and grant
options to purchase, shares of common stock under our option plans. In addition,
we may issue shares of common stock in connection with any acquisition of
another company if the terms of such issuance provide that such common stock
will not be resold prior to the expiration of the 180-day period referenced in
the preceding sentence. See "Risk Factors -- Investors may suffer substantial
dilution from other transactions." See "Shares Eligible for Future Sale."
 
     Prior to the offering, there has been no public market for the shares of
common stock. The initial public offering price will be negotiated between the
representatives and us. In determining the initial public offering price of the
common stock, the representatives will consider, among other things and in
addition to prevailing market conditions, our historical performance and capital
structure, estimates of our business potential and earning prospects, an overall
assessment of our management and the consideration of the above factors in
relating to market valuation of companies in related businesses.
 
     Application has been made to have the common stock approved for quotation
on the Nasdaq National Market under the symbol "HSAC."
 
     We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act, and to contribute, under certain
circumstances, to payments that the underwriters may be required to make in
respect thereof.
 
     Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters and
certain selling group members to bid for and purchase shares of common stock. As
an exception to these rules, the representatives are permitted to engage in
certain transactions that stabilize the price of common stock. Such transactions
may consist of bids or purchases for the purpose of pegging, fixing or
maintaining the price of the common stock.
 
     If the underwriters create a short position in the common stock in
connection with the offering (i.e., they sell more shares than are set forth on
the cover page of this prospectus), the representatives may reduce that short
position by purchasing common stock in the open market. The representatives also
may elect to reduce any short position by exercising all or part of the
over-allotment option described herein. The underwriters have informed us that
they do not intend to confirm sales to discretionary accounts that exceed 5% of
the total number of shares of common stock offered by them.
 
     The representatives also may impose a penalty bid on certain underwriters
and selling group members. This means that if the representatives purchase
shares of common stock in the open market to reduce the underwriters' short
position or to stabilize the price of the common stock, they may reclaim the
amount of the selling concession from the underwriters and selling group members
who sold those shares as part of the offering.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid could have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
an offering.
 
     Neither we nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the common stock. In addition, neither
we nor any of the underwriters makes any representation that the representatives
will engage in such transactions or that such transactions, once commenced, will
not be discontinued without notice.

     Any offers in Canada will be made only pursuant to an exemption from the
requirements to file a prospectus in the relevant province of Canada in which

     Purchasers of the shares of common stock offered in this prospectus may be
required to pay stamp taxes and other charges under the laws and practices of
the country of purchase, in addition to the offering price listed on the cover

     At our request, the underwriters have reserved up to 5% of the common stock
offered hereby for sale to certain of our employees, directors and friends at
the initial public offering price set forth on the cover page of this
prospectus. Such persons must commit to purchase no later than the close of
business on the day following the date of this prospectus. The number of shares
available for sale to the general public will be reduced to the extent such
persons purchase such reserved shares.

Board of Directors
High Speed Access Corp.
 
     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statement of operations, changes in stockholders' deficit and of
cash flows present fairly, in all material respects, the consolidated financial
position of High Speed Access Corp. and Subsidiaries at December 31, 1998 and
the results of their operations and their cash flows for the period from April
3, 1998 (inception) through December 31, 1998, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for the opinion expressed above.

1. THE COMPANY AND BASIS OF PRESENTATION
 
  The Company
 
     High Speed Access Corp. and Subsidiaries (the Company) provides high speed
Internet access via cable modems to residential and commercial customers in
exurban areas. The Company is among the first providers to offer cable
modem-based high speed Internet access in exurban markets. The Company defines
exurban markets as cable systems with fewer than 100,000 homes passed which it
estimates includes approximately 48 million homes, or approximately one-half of
the homes passed by cable in the United States. The Company enters into
long-term exclusive contracts with cable system operators to provide them with a
comprehensive "turnkey" service. That service enables a cable system's customers
to receive high speed Internet access. In exchange for providing the Company
with access to its customers, the Company pays the cable operator a portion of
the monthly fees received from an end user that subscribes to the services. The
Company operates in one business segment.
 
  Business Combination and Basis of Presentation
 
     On April 3, 1998, the Company issued 4,000,000 shares of common stock and
1,000,000 of Series A Preferred Stock for all of the outstanding stock of High
Speed Access Network, Inc. (HSAN) and CATV.net, Inc. (CATV) (together, the
"Predecessors"). The holders of the Series A preferred stock issued in the
transactions owned redeemable convertible preferred stock with a fair value of
$500 in each of HSAN and CATV at the time of the transaction. The Company valued
the common stock issued in the acquisition of the Predecessors at $.80 per share
and valued the Series A mandatorily redeemable convertible preferred stock
issued in the acquisition at $1.00 per share. The Series A mandatorily
redeemable convertible preferred stock was valued based on the sales prices of
similar securities issued by the Predecessors in nearly contemporaneous
transactions. In connection with the purchase of CATV, the Company issued 60,000
stock options in exchange for options held by CATV employees. The options were
valued at $15 based upon a valuation using an established option pricing model.
The value of options issued has been included in the calculation of the purchase
price of the Predecessors and is reflected in additional paid-in capital in the
accompanying consolidated financial statements.
 
     The acquisitions have been accounted for as purchases. Accordingly, the
assets and liabilities of the Predecessors were recorded at their fair values as
of the acquisitions. The accompanying statement of operations includes the
results of the Predecessors subsequent to April 3, 1998.
 
     Assets acquired and liabilities assumed in the transaction were as follows:

2. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The consolidated financial statements for the period ended December 31,
1998 include the operations of the Company for the period from April 3
(inception) through December 31, 1998. All significant intercompany transactions
and balances have been eliminated in consolidation.
 
  Revenue Recognition
 
     Monthly customer subscription revenue, consisting of fees for cable-modem
Internet access services and traditional dial-up services, is reported net of
the contractual share paid to cable system operators and is recognized as
services are provided. Included in subscription revenues are revenues related to
the rental of cable modems to customers in connection with subscription
contracts. Rental revenue under such agreements is directly related to the
customer's subscription agreement and is recognized ratably over the rental
period. Subscription revenue and revenue from rentals of cable modems to
customers billed in advance are recorded as deferred revenue initially and
recognized as income in the period in which the services are provided.
 
  Long-Lived Assets
 
     The Company reviews for the impairment of long-lived assets and certain
identifiable intangibles whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. An impairment loss
would be recognized when estimated future cash flows expected to result from the
use of the asset and its eventual disposition is less than its carrying amount.
No such impairment losses have been identified by the Company.
 
  Property, Equipment and Improvements
 
     Property, equipment and improvements are stated at cost. Depreciation and
amortization are computed using the straight-line method over the estimated
useful life of the assets for equipment and software (3 years) and furniture and
fixtures (5 years), or the shorter of useful life or lease term for leasehold
improvements or capital leases. Retirements, sales and disposals of assets are
recorded by removing the cost and accumulated depreciation from the accounts
with any resulting gain or loss recognized in income.
 
  Intangible Assets
 
     The excess of cost over net identifiable assets acquired in the purchases
of the Predecessors has been recorded as goodwill and is being amortized over
five years on a straight-line basis. Amortization expense for the period ended
December 31, 1998 was $626. In connection with the acquisition of HSAN, the
Company recognized an intangible asset of $80 for the acquisition of a customer
base from an internet service provider. The customer base acquisition cost is
being amortized over a three year period on a
                                       F-8

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
straight-line basis. Amortization expense of customer acquisition cost for the
period ended December 31, 1998 was $22.
 
  Capitalized Software Costs
 
     The Company capitalizes costs associated with the design and implementation
of internal use software, including internally and externally developed
software, in accordance with American Institute of Certified Public Accountants
(AICPA) Statement of Position (SOP) 98-1. Capitalized external software costs
include the actual costs to purchase existing software from vendors. Capitalized
internal software costs generally include personnel costs incurred in the
enhancement and implementation of purchased software packages.
 
  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 liabilities and are measured
using the enacted tax rates and laws that will be in effect when the differences
are expected to reverse.
 
  Stock-based Employee 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 requirements
of Statement Financial of Accounting Standards No. 123, "Accounting for
Stock-Based Compensation" (SFAS 123).
 
  Fair Value of Financial Instruments
 
     The Company's financial instruments principally consist of cash and cash
equivalents, accounts receivable, accounts payable, and capital lease
obligations that are carried at cost, which approximates fair value because of
the short-term nature of these instruments. Notes payable are with related
parties, and as a result, while the Company believes that the fair value of such
instruments approximates carrying value, the fair value is not readily
determinable.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include all short-term, highly liquid investments
that mature within three months of their acquisition date. At December 31, 1998
cash equivalents consist principally of interest-bearing demand deposit accounts
with a single financial institution.
 
  Engineering
 
     Engineering costs are expensed as incurred.
 
  Concentration of Credit Risk
 
     The Company's customers consist of residential and commercial customers in
the various markets served by the Company. As such, no single customer accounted
for greater than 10% of total revenues or accounts receivable balances for the
period ended December 31, 1998. The Company maintains an allowance for doubtful
accounts receivable based upon its historical experience and the expected
collectibility of all accounts receivable. The Company recorded an allowance for
doubtful accounts of $3 related to the accounts receivable acquired from CATV
and has recorded an additional allowance of $10 during the period ended December
31, 1998.

  Unaudited Pro Forma Information
 
     The Company is planning to file a registration statement with the
Securities and Exchange Commission that would permit the Company to sell shares
of common stock in an initial public offering (IPO). The unaudited pro forma
balance sheet information and the pro forma net loss per share reflect the
effects of the automatic conversion of all series of the Company's mandatorily
redeemable convertible preferred stock to common stock upon the closing of the
IPO. The unaudited pro forma information gives effect to the conversion of
accrued dividends on mandatorily redeemable convertible preferred stock into
shares of common stock based upon the accrued dividends of $385 as of December
31, 1998 and a conversion price of $6.50 per share. The per share conversion
price is based upon an independent appraisal. Actual dividends and the
conversion price will be different upon actual conversion.
 
  Recent Accounting Pronouncements
 
     In April 1998, the American Institute of Certified Public Accountants
(AICPA) issued SOP 98-5, Reporting on the Costs of Start-Up Activities. SOP
98-5, which is effective for fiscal years beginning after December 15, 1998,
provides guidance on the financial reporting of start-up costs and organization
costs. It requires costs of start-up activities and organization costs to be
expensed as incurred. As the Company has expensed these costs, the adoption of
this standard is not expected to have a significant impact on the Company's
results of operations, financial position or cash flows.
 
     In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 133 Accounting for Derivatives
and Hedging Activities (SFAS 133), which establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts (collectively referred to as derivatives) and for
hedging activities. SFAS 133 is effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. As the Company does not currently engage or
plan to engage in derivatives, or hedging transactions there will be no impact
to the Company's results of operations, financial position or cash flows upon
the adoption of SFAS 133.
 
  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.

4. LEASE OBLIGATIONS
 
     The Company leases certain office facilities under non-cancelable operating
leases that expire at various dates through 2003, 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. Facility
rent expense for the period ended December 31, 1998 was $144.
 
     The Company also has obligations under capital equipment leases. Future
minimum lease payments under non-cancelable operating and capital leases having
terms in excess of one year as of December 31, 1998 are as follows:

5. INCOME TAXES
 
     As of December 31, 1998, the Company had deferred tax assets of
approximately $3,780 primarily related to federal and state net operating loss
carryforwards. The net deferred tax asset has been fully offset by a valuation
allowance based upon the Company's history of operating losses. The federal and
state net operating loss carryforwards of approximately $8,500 at December 31,
1998 expire in 2018. Utilization of these net operating losses may be subject to
a substantial annual limitation based upon changes in the Company's ownership as
provided as provided in Section 382 of the Internal Revenue Code of 1986 and
similar state provisions. The annual limitation may result in the expiration of
net operating losses before utilization.
 
6. RETIREMENT PLAN
 
     The Company has established a deferred compensation plan in accordance with
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
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.

</TABLE>
 
     The first 1,000,000 shares of Series A Preferred Stock were issued in
exchange for 500,000 shares of redeemable convertible preferred stock of each of
HSAN and CATV in the acquisition on April 3, 1998. The remaining Series A shares
were issued from April through August 1998. Series B shares were issued from
September through November 1998.
 
     Preferred Stock ranks senior to the common stock and equal with each other
with respect to the payment of dividends, distribution of assets, and rights
upon liquidation, dissolution or winding up of the Company.
 
  Dividends
 
     The holders of Preferred Stock are entitled to receive dividends in
preference to holders of common stock. Dividends accrue on the Series A, B and C
Preferred Stock at an annual rate of $.07, $.175 and $.35 per share,
respectively. Dividends accrue on each share from its date of issuance, whether
or not earned or declared by the Company. Such dividends are cumulative, and
must be paid before any dividend or distribution is declared on common stock.
Any accumulation of dividends on the Preferred Stock do not bear interest. In
lieu of cash, a holder of Preferred Stock is entitled to receive common stock
valued at its current fair market value.
 
  Liquidation
 
     Upon any liquidation of the Company, before any distribution is made to
holders of common stock, the holders of Preferred Stock are entitled to receive
from the assets of the Company the issue price per share for the Series plus a
25% percent compounded annual return on the investment, less any dividends
already paid on the shares. However, if the amount to be distributable for each
share of common stock, assuming conversion of the Preferred Stock plus accrued
and unpaid dividends to common stock, is higher, the holders of the Preferred
Stock may elect to receive that per share amount.
 
     In the case of the sale or merger of the Company, as defined, the holders
of Preferred Stock are permitted to convert their Preferred Stock in a manner
that will allow the holder to obtain the issue price for the shares plus a 25%
compounded annual return on the investment, less any dividends paid on the
shares. If the Company issues common shares, or warrants, options, convertible
securities or other securities entitling the holders to obtain common stock, for
a consideration per share which is less than the issue price of the Preferred
Stock, then the conversion price is to be adjusted to reflect the lower price.
In such an instance, the holders of the Preferred Stock would be able to receive
additional common shares upon conversion. The terms of the conversion are also
adjusted in the case of stock splits and dividends, capital reorganizations and
other specified events to allow the holders of Preferred Stock to receive the
same rights that would have been received had the conversion taken place before
the event occurred.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Redemption
 
     If the Company has not completed a qualified IPO of common stock, the
holders of Preferred Stock may require the Company to redeem the shares on or
after April 3, 2003 in the case of Series A, and on or after November 25, 2003
in the case of Series B and C. The required redemption price is to be the
greater of the initial purchase price plus accrued but unpaid dividends or the
fair value per share based on a qualified appraisal acceptable to both the
Company and the holders of Preferred Stock. The shares of Preferred Stock are
not redeemable at the Company's option.
 
     As a result of these provisions, the Company accrued dividends of $190 on
Series A and $195 on Series B as of December 31, 1998. In addition, the Company
charged $119,282 to its accumulated deficit during 1998 to increase the carrying
value of the Preferred Stock to its estimated redemption value at December 31,
1998, as based upon a valuation by an independent party of $9.41 per share for
Series A and $10.22 per share for Series B Preferred Stock.
 
  Conversion
 
     Each Series of Preferred Stock is convertible at the option of the holder
into an equal number of shares of common stock. Upon conversion of any share of
Preferred Stock, all accrued but unpaid dividends are to be paid in shares of
common stock based on the fair value of the common stock (or the IPO price, if
applicable) at the date of the conversion. The Company is required to reserve a
sufficient number of authorized but unissued common shares to allow for the
Preferred Stock conversion rights to be satisfied. Each share of Preferred Stock
is to be automatically converted to common stock immediately upon the closing of
a qualified IPO.
 
  Voting Rights
 
     All shares of Preferred Stock have voting rights. Each share has the number
of votes equal to the number of shares of common stock into which the Preferred
Stock are convertible. In addition, the Company must obtain the consent from the
holders of a majority of each Series of Preferred Stock outstanding in order to
pursue certain specific actions. For purposes of this consent, each share of
Preferred Stock has one vote in determining whether a majority of the shares of
the class will vote to consent to the action.
 
     The specified actions which require consent include: a liquidation or
substantial change of the Company's business; amendment of the Company's bylaws
in most instances; redemption of common stock, or paying dividends or
distributions to common shareholders without redeeming or paying equal dividends
on the Preferred Stock; issuance of new equity shares except in certain
instances; certain transactions with shareholders or officers; any merger or
sale of substantially all of the Company's assets; acquisition of any assets for
a purchase price in excess of $2,500, or a series of transactions with an
aggregate purchase price in excess of $7,500; or any action that would
materially and adversely affect the holders of the Preferred Stock. However,
should either of the holders of a majority of a Series of Preferred Stock
transfer more than 30% of their holdings in the Company's stock, as defined,
then the company does not thereafter require the consent of the Series of shares
controlled by that investor.
 
     A Voting Agreement provides for four members of the Company's Board of
Directors to be named by Broadband Solutions and three members of the board of
directors to be named by Vulcan Ventures, Inc. The Voting Agreement specifies
the conditions under which, based on reductions of either investor's investment
in the company, an investor may lose the right to name one or more directors.
 
     The consent provisions discussed above and the Voting Agreement terminate
upon the completion of a qualified IPO, upon consent of each party or after ten
years.

  Adjustment of Terms
 
     The terms of the Preferred Stock with respect to dividends, liquidation,
redemption, conversion and voting rights are adjusted upon a stock split,
dividend or other recapitalization to maintain the same rights that would have
been received before the recapitalization under the original terms. Upon an IPO,
all Preferred Stock is automatically converted to common stock and all
preferential rights are terminated.
 
8. TRANSACTIONS WITH VULCAN VENTURES, INC.
 
     On November 25, 1998, the Company entered into a series of agreements with
Vulcan Ventures Incorporated (Vulcan), in which the Company issued shares of
Preferred Stock to Vulcan and entered into agreements under which it will
provide Internet access services to customers in certain cable systems
controlled by Vulcan.
 
     The Company issued 8,000,000 shares of its Series B Preferred Stock to
Vulcan at a purchase price of $2.50 per share. The Company also agreed to sell,
and Vulcan to buy, 2,500,000 shares of Series C Preferred Stock for $12.5
million if certain conditions are met. If the Company does not perform in all
material respects with all of the specified financial performance milestones or
the Board of Directors can not reasonably demonstrate that the Company needs the
cash during the next 12 months, then Vulcan will not be obligated to purchase
the Series C shares. Vulcan also has the option to acquire 2,500,000 additional
shares of Series C Preferred Stock at $5 per share. The commitment to issue the
Series C Preferred shares to Vulcan expires on November 25, 2000.
 
     In November 1998, the Company entered into a systems access and investment
agreement with Vulcan and Charter Communications (Charter), a programming
content agreement with Vulcan, and a related network services agreement with
Charter. Under these agreements, Charter committed to provide the Company
exclusive access to at least 750,000 homes passed, and has an equity incentive
to provide the Company additional homes passed, although it is not obligated to
do so. Charter can terminate these exclusivity rights, on a system-by-system
basis, if we fail to meet performance benchmarks or otherwise breach our
agreement. Charter can terminate the agreement without cause as long as it
purchases the associated cable head end equipment and modems at book value and
pays the Company a termination fee based on the net present value of the
revenues the Company otherwise would earn for the remaining term of the
agreement from end users subscribing to the Company's services as of the
termination date. During the term of the agreements, the Company has agreed not
to compete with Charter in any market in which it owns or operates a cable
system and will not deploy Worldgate, TV(R) or various other digital TV products
in the market areas of any committed system or in areas in which Charter
operates a cable system. The agreements will continue until the Company ceases
to provide services to an end user residing in a home passed in a committed
system.
 
     The Company also agreed to issue a warrant to Vulcan that will, in the
aggregate, entitle Vulcan to purchase 5,000,000 shares of the Company's common
stock at a purchase price of $5.00 per share. The warrants become exercisable at
the rate of one share of common stock for each home passed in excess of 750,000.
A maximum of 2,500,000 warrants may be earned by Vulcan on or before July 31,
2001, and a maximum of 2,500,000 warrants may be earned by Vulcan on or before
July 31, 2003. Each warrant issued to Vulcan must be exercised on or before one
year from the effective date of an IPO. The warrants may be forfeited in certain
circumstances, generally if the number of homes passed in committed systems is
reduced. As of December 31, 1998, the Company had issued no warrants to purchase
shares of common stock to Vulcan.
 
     The Company will recognize an addition to equity for the fair value of any
warrants issued, and recognize the related expense over the term of the service
agreement with the cable system to which the warrants relate, generally four to
five years, in accordance with Emerging Issues Task Force Issue

9. STOCK OPTION PLAN
 
     In April 1998, the Company's Board of Directors adopted the 1998 Stock
Option Plan (the Plan). A total of 900,000 shares of common stock were reserved
for issuance under this Plan.
 
     The exercise price for the options is determined by the Board of Directors,
but shall not be less than 100% of the estimated fair market value of the common
stock on the date the option is granted. Generally, the options vest over a
five-year period after the date of grant and expire ten years after the date of
grant. The Plan provides for accelerated vesting should there be a change in
control or a qualified IPO of the Company's common stock. Option holders that
terminate their employment with the Company forfeit all non-vested options.
Employees, key advisors and non-employee directors of the Company are eligible
to receive awards under the Plan.
 
     The following table summarizes the activity in the Plan:

     Options to acquire 86,800 additional shares at an exercise price of $5.00
per share were issued in January 1999.
 
     The Company applies Accounting Principles Board Opinion No. 25, "Accounting
for Stock-Issued to Employees" and related interpretations in accounting for its
stock option plan. Under APB No. 25, compensation expense is recognized based on
the amount by which the fair value of the Company's common stock exceeds the
exercise price of the stock options at the date of grant. Stock options with an
exercise price of $1.00 and $2.50 were granted with an exercise price equal to
the price per share at which Preferred Stock was issued during the month in
which the options were granted. Stock options granted with an exercise price of
$5 in December were later determined to be compensatory based on the results of
an independent appraisal and the Company will recognize expense of approximately
$84 over the five year vesting period of the options. Recognition of this
expense will be accelerated to the period in which a change in control or a
qualified IPO occurs. Expense recognized in 1998 was insignificant.

     The Company has adopted the disclosure only provisions of SFAS 123. The
weighted average fair value of stock options granted was $.55. Had compensation
expense been recognized pursuant to SFAS 123, the Company's net loss would have

     The Company adopted the 1999 Stock Option Plan and the 1999 Non-Employee
Directors Plan in January 1999. Under the 1999 Stock Option Plan, 2,000,000
shares are reserved for issuances. Options to purchase 30,000 shares were
granted with an exercise price of $5.00 per share and options to purchase 31,000
shares were granted with an exercise price equal to the greater of $10.00 or the
IPO price per share. None of the options under this plan are currently
exercisable.
 
     Under the 1999 Directors Plan, options to purchase 122,500 shares with an
exercise price of $5.00 per share, all of which were immediately exercisable,
were granted in January 1999. Under the 1999 Directors Plan, 300,000 shares are
reserved for issuances.
 
10. EARNINGS (LOSS) PER SHARE
 
     The Company computes net loss per share under the provisions of SFAS No.
128 "Earnings per Share" (SFAS 128) and SEC Staff Accounting Bulletin No. 98
(SAB 98). Under the provisions of SFAS 128 and SAB 98, basic and diluted net
loss per share is computed by dividing the net loss available to common
stockholders for the period by the weighted average number of shares of common
stock outstanding during the period. The calculation of diluted net loss per
share excludes potential common shares if the effect is antidilutive. Basic
earnings per share is computed by dividing income or loss applicable to common
shareholders by the weighted average number of shares of common stock
outstanding during this period.
 
     Diluted earnings per share is determined in the same manner as basic
earnings per share except that the number of shares is increased assuming
exercise of dilutive stock options and warrants using the treasury stock method
and assuming conversion of the Company's Preferred Stock. In addition, income or
loss is adjusted for dividends and other transactions relating to preferred
shares for which conversion is assumed. The diluted earnings per share amount
equals basic earnings per share because the Company has a net loss and the
impact of the assumed exercise of the stock options and the assumed preferred
stock conversion is not dilutive.

                    HIGH SPEED ACCESS CORP. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Under the Company's Certificate of Incorporation, all outstanding Preferred
Stock will convert into Common Stock on a one-for-one basis as adjusted for any
stock splits, upon the closing of the Company's IPO of Common Stock. The
unaudited pro forma net loss per share assumes the conversion of the Preferred
Stock to Common Stock as if it had been converted at the date of issuance, even
though the result is antidilutive.
 
     The following table presents the calculation of basic and diluted and pro
forma net loss per share:

11. RELATED PARTY TRANSACTIONS
 
  General
 
     In November 1998, the Company entered into a systems access agreement with
Vulcan, Charter and Marcus a programming content agreement with Vulcan, and a
related networks services agreement with Charter and Marcus, pursuant to which
Vulcan, Charter and Marcus retained the Company to offer and provide Internet
access and related services to cable customers of various cable systems owned
and operated by Charter and Marcus. Vulcan is a significant stockholder and has
the right to name three of the members of the Company's board of directors. See
Note 8 "Transactions with Vulcan Ventures, Inc." for more information on these
agreements.
 
     The Company has an agreement with Gans Multimedia Partnership, an entity
owned by Joseph S. Gans, III, a founder and former director of HSA, under which
Gans Multimedia granted the Company the exclusive right to provide the customers
of two cable systems owned by Gans Multimedia with high speed Internet access.
The agreement has a five year term and provides that Gans Multimedia will
receive 25% of the gross revenues the Company receives under the agreement.
During 1998, the Company paid Gans Multimedia $76 under the agreement.
 
     The Company has an agreement to pay $20 each quarter for financial
consulting services provided by a private investment firm managed by two of the
Company's directors. The Company has a payable of $60 to the private investment
firm at December 31, 1998. These fees are payable upon the earlier of a
determination by the Company's Board of Directors that the Company has
sufficient cash flow to pay the fees or the Company achieves $100 or more in
after-tax quarterly profits for two consecutive quarters.
 
     An officer of the Company is associated with a private company that entered
into a service agreement with the Company to provide certain financial,
accounting, professional staffing and legal services to the

Company. The Company paid fees of $71 relating to these services during the
period ended December 31, 1998. This service agreement was terminated on
December 31, 1998. The private company also leased certain equipment to the
Company as described in Note 4. Lease payments paid by the Company on this
capital lease were $6.
 
  Notes Payable -- Related Party
 
     During October, 1998, Broadband Solutions, LLC, the holder of the Series A
Preferred Stock, made a loan to the Company of $1,000 bearing interest at 12%
which was exchanged for 400,000 shares of Series B preferred stock on November
13, 1998. Interest paid to Broadband Solutions, LLC was $11.
 
     As part of its acquisition of HSAN, the Company assumed a note payable in
the aggregate principal amount of $ 650, evidenced by a promissory note and
assignment and security agreement, owing to Gans Multimedia Partnership. The
note bears interest at a rate of 7% per annum. The Company repaid $150 of the
note in December 1998 and the remaining $500 balance matures on April 1, 2001.
Certain tangible assets of the Company serve as collateral for this note. The
loan represents working capital of HSAN funded by Gans Multimedia Partnership
from July 1997 to April 1998.
 
     As part of its acquisition of CATV, the Company assumed a note payable in
the aggregate principal amount of $44, evidenced by a promissory note and
assignment and security agreement, from a private company associated with an
officer of the Company. The note bears interest at a rate of 7% per annum. The
Company paid $6 of the note prior to December 31, 1998, with the remaining
balance of $38 payable in monthly installments of approximately $1 through
February 5, 2003. The loan represents working capital of CATV funded by the
private company from March 1998 to April 1998.
 
     The aggregate amounts of notes payable -- related parties maturities are as

12. COMMITMENTS AND CONTINGENCIES
 
     The Company is not a party to any material legal proceedings. In the
opinion of management, the amount of ultimate liability with respect to any
known actions will not materially affect the financial position of the Company.
 
13. RISKS AND UNCERTAINTIES
 
  Requirements for Additional Financing
 
     The Company expects to experience substantial negative cash flows from
operating activities and investing activities for at least the next several
years due to the deployment of its services into new markets and the enhancement
of its network and operations. During 1998, the Company has raised cash through
the sale of the Company's mandatorily redeemable convertible preferred stock. At
December 31, 1998, the primary source of liquidity for the Company was $17,888
of cash and cash equivalents. The Company believes that additional financing of
$25 million will be obtained from the planned sale of Series C Preferred Stock
to Vulcan Ventures. The Company also intends to obtain additional equity from
 
                                      F-18
<PAGE>   95
                    HIGH SPEED ACCESS CORP. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
an initial public offering of its common stock during 1999. Other financing may
be obtained from debt and leasing activities, among other alternatives.
Management believes these financing sources will be sufficient to meet the
Company's working capital requirements, including operating losses, and capital
expenditure requirements for at least the next 18 months. There can be no
assurance as to the availability or terms upon which such financing and equity
might be obtained. If financing is not available at terms acceptable to the
company, management has the intent and believes it has the ability to reduce
expenditures so as to delay the need for additional financing.
 
  Dependence on Key Technology Suppliers and Cable Companies
 
     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. Should the Company not obtain additional
cable systems for distribution, it could have a material, adverse effect on the
Company's financial condition and results of operations.
 
     The Company's business plan is dependent on cable companies to distribute
its service to its subscribers. The Company has an agreement with several of its
shareholders to provide exclusive Internet access on certain cable systems
controlled by them. However, there is no guarantee that the shareholders will
provide additional cable systems for distribution by the Company. In addition,
the Company's agreements with individual cable systems are for terms of no more
than 5 years, and they may be terminated prior to that date under certain
circumstances.
 
     The Company's ability to provide its services is also dependent on the
availability and reliability of the infrastructure of the cable system
operators. Currently, many cable system operators in the Company's markets and
potential markets have not upgraded their systems to allow the Company to
efficiently provide its services. These cable system operators are under no
obligation to undertake an upgrade of their systems, and the Company is
therefore dependent on cable system operators to make the improvements that will
allow the Company to provide its services.
 
14. SUBSEQUENT EVENTS
 
  Initial Public Offering
 
     In February 1999 the Board of Directors authorized the filing of a
registration statement with the Securities and Exchange Commission that would
permit the Company to sell shares of the Company's common stock in connection
with a proposed IPO. The Board has authorized the sale of $5,000 of common stock
to Cisco Systems, Inc., in a concurrent offering.
 
  Distribution to Stockholders of Darwin Networks, Inc.
 
     In March 1999, the Company transferred to Darwin Networks, Inc., a newly
created Delaware corporation, all of the assets used in the Company's digital
subscriber line service in exchange for 100% of the outstanding Darwin common
stock. Prior to its IPO, the Company will distribute all of the outstanding
Darwin common stock to the Company's stockholders on a pro rata basis. In
connection with the asset transfer, the Company entered into a services
agreement with Darwin pursuant to which it will provide various financial,
accounting and other professional staff services to Darwin and will be
compensated for its costs at fair market value. The Company also entered into a
sublease pursuant to which Darwin will sublease office space in the Company's
Louisville, Kentucky offices at a monthly rent based on the fair

market value of such space. The services agreement and sublease are for an
initial six month term. The Company also agreed to loan Darwin up to $500 for
working capital pursuant to a six month uncollateralized revolving credit note
bearing interest at the prime rate. In connection with the note, Darwin will
issue to the Company a warrant to purchase 1,000,000 shares of Darwin common
stock at an exercise price of $5.00 per share. Expenses related to the Darwin
service line approximated $175 in 1998. No revenue was realized in 1998
associated with Darwin.

                      FOR THE PERIODS FROM MARCH 12, 1997
                     (INCEPTION) THROUGH DECEMBER 31, 1997

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The Company
 
     CATV.net, Inc. ("the Company") provides high speed Internet access via
cable modems to residential and commercial customers in exurban areas. The
Company enters into long-term exclusive contracts with cable system operators to
provide them with a comprehensive "turnkey" service. That service enables a
cable system's customers to receive high speed Internet. In exchange for
providing the Company access to its customers, the cable operator receives a
portion of the monthly fees received from the customer that subscribes to the
services.
 
     The Company also provides consulting services focused on enabling cable
operators to provide Internet access services and sells related equipment to the
operator. In addition, the Company installs cable modems for residential and
commercial customers generally through the use of independent contractors.
 
  Basis of Presentation
 
     CATV.net LLC was organized on March 12, 1997. No capital contributions were
received in exchange for the member units issued upon inception. On January 1,
1998, CATV.net LLC issued 100,000 additional member units in repayment of $117
due to one of its officers. On February 23, 1998, CATV.net LLC reorganized as a
corporation, CATV.net Inc., without changing its ownership. Also on February 23,
1998, CATV.net Inc. entered into a Convertible Preferred Stock Purchase
Agreement with Broadband Solutions LLC ("Broadband Solutions"), an investor
group. Broadband Solutions agreed to purchase 2,500,000 shares of Preferred
Stock from CATV.net LLC for $1 per share. Broadband paid for the purchase of the
first 500,000 shares on February 23, 1998.
 
     On April 3, 1998, the Company effected a 10-to-1 split of its common and
mandatorily redeemable convertible preferred stock. All balances of the common
and mandatorily redeemable convertible preferred stock have been adjusted to
reflect this stock split.
 
  Revenue Recognition
 
     Revenues from the sale of equipment and consulting services are recognized
when earned. Monthly customer subscription revenue is recognized in the period
in which subscription services are provided. Subscription revenue billed in
advance is deferred until the related services are provided.
 
  Long-Lived Assets
 
     The Company reviews for the impairment of long-lived assets and certain
identifiable intangibles whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. An impairment loss
would be recognized when estimated future cash flows expected to result from the
use of the asset and its eventual disposition is less than its carrying amount.
No such impairment losses have been identified by the Company.
 
  Property and Equipment
 
     Property, equipment, and improvements are stated at cost. Depreciation and
amortization are computed using the straight-line method over the estimated
useful life of the assets for equipment

(3 years) and furniture and fixtures (5 years), or the shorter of useful life or
lease term for capital leases. Retirements, sales and disposals of assets are
recorded by removing the cost and accumulated depreciation from the accounts
with any resulting gain or loss recognized in income.
 
  Stock-based Employee 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 requirements
of Statement of Financial Accounting Standards No. 123, Accounting for
Stock-Based Compensation (SFAS 123).
 
  Fair Value of Financial Instruments
 
     The Company's financial instruments principally consist of cash and cash
equivalents, accounts receivable, accounts payable, and capital lease
obligations that are carried at cost, which approximates fair value because of
the short-term nature of these instruments. Notes payable are with related
parties, and as a result, while the Company believes that the fair value of such
instruments approximates carrying value, the carrying amount may not necessarily
reflect fair value.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include all short-term, highly liquid investments
that mature within three months of their acquisition date.
 
  Engineering
 
     Engineering costs are expensed as incurred.
 
  Concentration of Credit Risk
 
     The Company's customers consist of residential and commercial customers in
the various markets served by the Company. As such, no single customer accounted
for greater than 10% of total revenues or accounts receivable balances for the
periods ended December 31, 1997 and April 2, 1998. The Company maintains an
allowance for doubtful accounts receivable based upon its historical experience
and expected collectibility of all accounts receivable.
 
  Recent Accounting Pronouncements
 
     In April 1998 the American Institute of Certified Public Accountants issued
Statement of Position 98-5, Reporting on the Costs of Start-Up Activities (SOP
98-5). SOP 98-5, which is effective for fiscal years beginning after December
15, 1998, provides guidance on the financial reporting of start-up costs and
organization costs. It requires costs of start up activities and organization
costs to be expensed as incurred. As the Company has expensed these costs, the
adoption of this standard is not expected to have a significant impact on the
Company's results of operations, financial position or cash flows.
 
     In June 1998 the Financial Accounting Standards Board issued Accounting for
Derivatives and Hedging Activities (SFAS 133), which establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives) and for hedging activities. SFAS 133 is effective for all fiscal
quarters of fiscal years beginning after June 15, 1999. As the Company does not
currently engage or plan to engage in derivatives, there will be no impact to
the Company's results of operations, financial position or cash flows upon the
adoption of SFAS 133.

     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.
 
2. PROPERTY, EQUIPMENT AND IMPROVEMENTS
 
     The components of property, equipment and improvements are as follows:

3. LEASE OBLIGATIONS
 
     The Company leases certain office facilities on a month-to-month basis,
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. Facility rent expense for the periods ended December 31,
1997 and April 2, 1998 amounted to $2 and $3 respectively.
 
     The Company also has obligations under capital equipment leases. The
capital lease is with a company affiliated with an officer of the Company.
Future minimum lease payments capital leases having terms in excess of one year
as of April 2, 1998 are as follows:

4. INCOME TAXES
 
     The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards (SFAS 109) Accounting for Income Taxes which
provides for the establishment of deferred tax assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes. As of
April 2, 1998, the Company had deferred tax assets of approximately $53
primarily related to federal and state net operating loss carryforwards. The net
deferred tax asset has been fully offset by a valuation allowance based upon the
Company's history of operating losses. The federal and state net operating loss
carryforwards of approximately $133 at April 2, 1998 expire in 2018. Utilization
of these net operating losses may be subject to a substantial annual limitation
provided by the Internal Revenue Code of 1986 and similar state provisions. The
annual limitation may result in the expiration of net operating losses before
utilization.
 
     Prior to the February 23, 1998 conversion of the Company from a limited
liability company to a corporation (CATV.net, Inc.), the Company was treated as
a flow-through entity for federal income tax purposes. The losses of the Company
were reported by its members on their individual federal and state income tax
returns, and CATV.net LLC did not pay income taxes or receive income tax
benefits.
 
5. MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK
 
     Outstanding mandatorily redeemable convertible preferred stock, ("Preferred
Stock") at April 2, 1998 consists of the following:

</TABLE>
 
     The Company issued 500,000 shares of its Preferred Stock on February 23,
1998. The holder of the Preferred Stock has subscribed to an additional
2,000,000 shares, payable at the option of the Company. The Preferred Stock
ranks senior to the common stock with respect to the payment of dividends,
distribution of assets, and rights upon liquidation, dissolution or winding up
of the company.
 
  Dividends
 
     The holders of Preferred Stock are entitled to receive dividends in
preference to holders of common shares. Dividends accrue on the shares at an
annual rate of $.07 per share. Dividends accrue on each share whether or not
earned or declared by the company. Such dividends are cumulative, and must be
paid before any dividend or distribution is declared on common stock. Any
accumulation of dividends on the preferred shares do not bear interest. In lieu
of cash, a holder of preferred shares is entitled to receive common stock valued
at its current fair market value.
 
  Liquidation
 
     Upon any liquidation of the Company, before any distribution is made to
common stock holders, the holders of Preferred Stock are entitled to receive
from the assets of the Company the issue price per share plus a 25% compounded
annual return on the investment, less any dividends already paid on the shares.
However, if the amount to be distributable for each share of common stock,
assuming conversion of the Preferred Shares plus accrued and unpaid dividends to
common shares, is higher, the holders of the Preferred Shares may elect to
receive that per share amount.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Redemption
 
     If the Company has not completed a qualified initial public offering of
common stock, the holders of Preferred Stock may require the Company to redeem
the shares on or after April 3, 2003. The required redemption price is to be the
greater of the initial purchase price plus accrued but unpaid dividends or the
fair value per share based on a qualified appraisal acceptable to both the
Company and the shareholder. The shares of preferred stock are not redeemable at
the Company's option.
 
  Conversion
 
     The Preferred Stock is convertible at the option of the holder into an
equal number of common shares. Upon conversion of any share of Preferred Stock,
all accrued but unpaid dividends are to be paid in shares of common stock based
on the fair value of the common stock at the date of the conversion. The Company
is required to reserve a sufficient number of authorized but unissued common
shares to allow for the Preferred Stock conversion rights to be satisfied. Each
share of Preferred Stock is to be automatically converted to common shares
immediately upon the closing of a qualified initial public offering.
 
     In the case of the sale or merger of the Company, as defined, the holders
of Preferred Stock are permitted to convert their Preferred Shares in a manner
that will allow the holder to obtain the issue price for the shares plus a 25%
compounded annual return on the investment, less any dividends paid on the
shares. If the company issues common shares, or warrants, options, convertible
securities or other securities entitling the holders to obtain common stock, for
a consideration per share which is less than the par value of the Preferred
Stock, then the conversion price is to be adjusted to reflect the lower price.
As a result, the holders of the Preferred Stock would be able to receive
additional common shares upon conversion. The terms of the conversion are also
adjusted in the case of stock splits and dividends, capital reorganizations and
other specified events to allow the holders of Preferred Stock to receive the
same rights that would have been received had the conversion taken place before
the event occurred. The holders of the Preferred Stock waived their right to
exercise this provision in the exchange of preferred shares on April 3, 1998.
 
  Voting
 
     All shares of preferred stock have voting rights. The number of votes per
preferred shares are adjusted so that at any time the total votes attributable
to Preferred Stock is equal to 2,500,000 common shares. As a result, the holders
of Preferred Stock have a majority voting interest in the Company at April 2,
1998.
 
6. STOCK OPTION PLAN
 
     In February 1998, the Company's Board of Directors adopted the 1998 Stock
Option Plan (the Plan). A total of 45,000 shares of common stock were reserved
for issuance under this Plan.
 
     The exercise price for the options is determined by the Board of Directors,
but shall not be less than 100% of the fair market value of the common stock on
the date the option is granted. Generally, the options vest over a five-year
period after the date of grant and expire ten years after the date of grant. The
Plan provides for accelerated vesting should there be a change in control, or an
initial public offering of the Company's common stock. Option holders that
terminate their employment with the Company forfeit all non-vested options.
Employees, key advisors and non-employee directors of the Company are eligible
to receive awards under the Plan.

     The Company applies APB No. 25, and related interpretations in accounting
for its stock option plan. Under APB No. 25, compensation expense is recognized
based on the amount by which the fair value of the Company's common stock
exceeds the exercise price of the stock options at the date of grant. No expense
was recognized during the period ended April 2, 1998.
 
     The Company has adopted the disclosure only provisions of SFAS 123. The
weighted average fair value of the options granted as of April 2, 1998 was $.24
per option. Had compensation expense been recognized pursuant to SFAS No. 123,
the Company's net loss would have been increased to the pro forma amounts
indicated below for the period ended April 21, 1998:

7. RELATED PARTY TRANSACTIONS
 
     The Company incurred fees for financial advisory services provided by a
private investment firm managed by two of the Company's directors. Total fees
for these services were $7 for the period ended April 2, 1998.
 
     An officer of the Company is associated with a private company that entered
into a service agreement with the Company to provide certain financial,
accounting, professional staffing and legal services to the Company. The Company
paid fees of $1 and $28 relating to these services during the periods ended
December 31, 1997 and April 2, 1998, respectively.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     In February, 1998, the Company borrowed $44 from a private company
associated with an officer of the Company. The note bears interest at a rate of
7% per annum with monthly installments of approximately $1 through February 5,
2003. The loan represents working capital funded by the private company from
March 1998 to April 1998.
 
8. RISKS AND UNCERTAINTIES
 
  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. Should the company not obtain additional
cable systems for distribution, it could have a material, adverse effect on the
Company's financial condition and results of operations.
 
  Dependence on Cable Companies
 
     The Company's business plan is dependent on cable companies to distribute
its service to its subscribers. The Company has an agreement with several of its
shareholders to provide exclusive Internet access on certain cable systems
controlled by them. However, there is no guarantee that the shareholders will
provide additional cable systems for distribution by the Company. In addition,
the Company's agreements with individual cable systems are for terms of no more
than 5 years, and they may be terminated prior to that date under certain
circumstances.
 
     The Company's ability to provide its services is also dependent on the
availability and reliability of the infrastructure of the cable system
operators. Currently, many cable system operators in the Company's markets and
potential markets have not upgraded their systems to allow the Company to
efficiently provide its services. These cable system operators are under no
obligation to undertake an upgrade of their systems, and the Company is
therefore dependent on cable system operators to make the improvements that will
allow the Company to provide its services.
 
9. SUBSEQUENT EVENTS
 
     The Company was acquired by High Speed Access Corp. in an exchange of stock
on April 3, 1998.

    FOR THE PERIODS FROM JULY 21, 1997 (INCEPTION) THROUGH DECEMBER 31, 1997

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The Company
 
     High Speed Access Network, Inc. (the "Company" and "HSAN") provides high
speed Internet access via cable modems to residential and commercial customers
in exurban areas. The Company enters into long-term exclusive contracts with
cable system operators to provide them with a comprehensive "turnkey" service.
That service enables a cable system's customers to receive high speed Internet
access. In exchange for providing access to its customers, the Company pays the
cable operator a portion of the monthly fees received from the customer that
subscribes to the services.
 
     The Company provides the necessary equipment to provide Internet access to
a cable operator's customer base. The Company installs its Internet equipment at
the head-end facilities of the cable operator and performs tests on the system.
Once the equipment is ready for use, the Company markets the services and
installs cable modems for residential and commercial customers, generally using
outside vendors to perform the cable modem installation process.
 
BASIS OF PRESENTATION
 
     HSAN was incorporated on July 1, 1997, with the issuance of 1 share of its
$.01 par value common shares. On April 2, 1998, HSAN's Board of Directors
approved the issuance of an additional 1,999,999 shares to the founder and four
employees and advisors. No proceeds were received from the issuance of the
additional shares. The issuance of the additional shares has been accounted for
as a 2,000,000 to 1 stock split in the accompanying financial statements.
Accordingly all prior period amounts reflect the stock split as if it had
occurred on July 21, 1997. The Company recognized compensation expense of $947
related to the issuance of 1,184,000 shares to employees and consultants for
services other than the founder. Compensation expense was recognized based on
the Company's estimate of the fair value of $.80 per common share per the common
stock issued.
 
     The Company issued 500,000 shares of mandatorily redeemable convertible
preferred stock occurred on April 3, 1998 just prior to the Company being
acquired by High Speed Access Corp. in a stock-for-stock transaction. Because
the Company's operations for April 3, 1998 are included in the financial
statements of the acquiring company, the financial statements of the Company
include the results of operations only through April 2, 1998.
 
  Revenue Recognition
 
     Monthly customer subscription revenue is recognized in the period in which
subscription services are provided. Subscription revenue billed in advance is
deferred until the related services are provided.
 
  Long-Lived Assets
 
     The Company reviews for the impairment of long-lived assets and certain
identifiable intangibles whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. An impairment loss
would be recognized when estimated future cash flows expected to result from the
use of the asset and its eventual disposition is less than its carrying amount.
No such impairment losses have been identified by the Company.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Property, Equipment and Improvements
 
     Property, equipment, and improvements are stated at cost. Depreciation and
amortization are computed using the straight-line method over the estimated
useful life of the assets for equipment (3 years) and furniture and fixtures (5
years), or the shorter of useful life or lease term for leasehold improvements.
Retirements, sales and disposals of assets are recorded by removing the cost and
accumulated depreciation from the accounts with any resulting gain or loss
recognized in income.
 
  Intangible Assets
 
     The Company recognized an intangible asset of $87 for the acquisition of a
customer base from an internet service provider in December 1997. The cost of
the customer base is being amortized over a three year period on a straight-line
basis. Amortization expense for the period ended April 2, 1998 was $7.
 
  Income Taxes
 
     The Company has elected to be taxed under Subchapter S of the Internal
Revenue Code. As a result, the Company's losses have been reported by the
shareholders on their individual federal and state income tax returns, and no
income tax expense or benefit has been recognized by the Company.
 
  Fair Value of Financial Instruments
 
     The Company's financial instruments principally consist of cash and cash
equivalents, accounts receivable, and accounts payable, that are carried at
cost, which approximates fair value because of the short-term nature of these
instruments, while the Company believes that the fair value of such instruments
approximates carrying value, advances from related parties may not necessarily
reflect fair value because of their nature.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include all short-term, highly liquid investments
that mature within three months of their acquisition date.
 
  Concentration of Credit Risk
 
     The Company's customers consist of residential and commercial customers in
the various markets served by the Company. As such, no single customer accounted
for greater than 10% of total revenues or accounts receivable balances for the
periods ended December 31, 1997 and April 2, 1998.
 
  Engineering
 
     Engineering costs are expensed as incurred.
 
  Recent Accounting Pronouncements
 
     In April 1998 the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) 98-5, Reporting on the Costs of
Start-Up Activities (SOP 98-5). SOP 98-5, which is effective for fiscal years
beginning after December 15, 1998, provides guidance on the financial reporting
of start-up costs and organization costs. It requires costs of start up
activities and organization costs to be expensed as incurred. As the Company has
expensed these costs, the adoption of this standard is not expected to have a
significant impact on the Company's results of operations, financial position or
cash flows.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     In June 1998 the Financial Accounting Standards Board issued Accounting for
Derivatives and Hedging Activities (SFAS 133), which establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives) and for hedging activities. SFAS 133 is effective for all fiscal
quarters of fiscal years beginning after June 15, 1999. As the Company does not
currently engage or plan to engage in derivatives, there will be no impact to
the Company's results of operations, financial position or cash flows upon the
adoption of SFAS 133.
 
  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.
 
2. PROPERTY, EQUIPMENT AND IMPROVEMENTS
 
     The components of property, equipment and improvements are as follows:

     Total depreciation and amortization expense for the periods ended December

3. LEASE OBLIGATIONS
 
     The Company leases certain office facilities under operating leases on a
month to month basis 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. Facility rent expense for the periods
ended December 31, 1997 and April 2, 1998 amounted to $5 and $12 respectively.
 
4. MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK
 
     Mandatorily redeemable convertible preferred stock ("Preferred Stock") at

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The 500,000 shares of Preferred Stock were issued on April 3, 1998.
Preferred Stock ranks senior to the common stock with respect to the payment of
dividends, distribution of assets, and rights upon liquidation, dissolution or
winding up of the Company.
 
  Dividends
 
     The holders of Preferred Stock are entitled to receive dividends in
preference to holders of common stock. Dividends accrue on the Preferred Stock
at an annual rate of $.07 per share, respectively. Dividends accrue on each
share from its date of issuance, whether or not earned or declared by the
Company. Such dividends are cumulative, and must be paid before any dividend or
distribution is declared on common stock. Any accumulation of dividends on the
Preferred Stock does not bear interest. In lieu of cash, a holder of Preferred
Stock is entitled to receive common stock valued at its current fair market
value.
 
  Liquidation
 
     Upon any liquidation of the Company, before any distribution is made to
common stock holders, the holders of Preferred Stock are entitled to receive
from the assets of the Company the issue price per share for the Series plus a
25% percent compounded annual return on the investment, less any dividends
already paid on the shares. However, if the amount to be distributable for each
share of common stock, assuming conversion of the Preferred Stock plus accrued
and unpaid dividends to common stock, is higher, the holders of the Preferred
Stock may elect to receive that per share amount.
 
  Redemption
 
     If the Company has not completed a qualified IPO of common stock, the
holders of Preferred Stock may require the Company to redeem the shares on or
after April 3, 2003. The required redemption price is to be the greater of the
initial purchase price plus accrued but unpaid dividends or the fair value per
share based on a qualified appraisal acceptable to both the Company and the
shareholders. The shares of preferred stock are not redeemable at the Company's
option.
 
  Conversion
 
     Each Series of Preferred Stock is convertible at the option of the holder
into an equal number of shares of common stock. Upon conversion of any share of
Preferred Stock, all accrued but unpaid dividends are to be paid in shares of
common stock based on the fair value of the common stock at the date of the
conversion. The Company is required to reserve a sufficient number of authorized
but unissued common shares to allow for the Preferred Stock conversion rights to
be satisfied. Each share of Preferred Stock is to be automatically converted to
common stock immediately upon the closing of a qualified IPO.
 
     In the case of the sale or merger of the Company, as defined, the holders
of Preferred Stock are permitted to convert their Preferred Stock in a manner
that will allow the holder to obtain the issue price for the shares plus a 25%
compounded annual return on the investment, less any dividends paid on the
shares. If the Company issues common shares, or warrants, options, convertible
securities or other securities entitling the holders to obtain common stock, for
a consideration per share which is less than the par value of the Preferred
Stock, then the conversion price is to be adjusted to reflect the lower price.
In such an instance, the holders of the Preferred Stock would be able to receive
additional common shares upon conversion. The terms of the conversion are also
adjusted in the case of stock splits and dividends, capital reorganizations and
other specified events to allow the holders of Preferred Stock to receive the
same rights that would have been received had the conversion taken place before
the event occurred.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Voting Rights
 
     All shares of Preferred Stock have voting rights. Each share has the number
of votes equal to the number of shares of common stock into which the Preferred
Stock are convertible.
 
     All shares of preferred stock have voting rights. The number of votes per
preferred shares are adjusted so that at any time the total votes attributable
to Preferred Stock is equal to 2,500,000 common shares. As a result, the holders
of Preferred Stock have a majority voting interest in the Company at April 2,
1998.
 
  Adjustment of Terms
 
     The terms of the Preferred Stock with respect to dividends, liquidation,
redemption, conversion and voting rights are adjusted upon a stock split,
dividend or other recapitalization to maintain the effects of the original
terms. Upon an IPO, all Preferred Stock is automatically converted to common
stock and all preferential rights are terminated.
 
5. RELATED PARTY TRANSACTIONS
 
     The founder of the Company made advances to the Company totalling $741 as
of December 31, 1997 and $922 as of April 2, 1998. No interest was charged on
their advances, which were due on demand.
 
6. RISKS AND UNCERTAINTIES
 
  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. Should the company not obtain additional
cable systems for distribution, it could have a material, adverse effect on the
Company's financial condition and results of operations.
 
  Dependence on Cable Companies
 
     The Company's business plan is dependent on cable companies to distribute
its service to its subscribers. The Company has an agreement with several of its
shareholders to provide exclusive Internet access on certain cable systems
controlled by them. However, there is no guarantee that the shareholders will
provide additional cable systems for distribution by the Company. In addition,
the Company's agreements with individual cable systems are for terms of no more
than 5 years, and they may be terminated prior to that date under certain
circumstances.
 
     The Company's ability to provide its services is also dependent on the
availability and reliability of the infrastructure of the cable system
operators. Currently, many cable system operators in the Company's markets and
potential markets have not upgraded their systems to allow the Company to
efficiently provide its services. These cable system operators are under no
obligation to undertake an upgrade of their systems, and the Company is
therefore dependent on cable system operators to make the improvements that will
allow the Company to provide its services.
 
7. SUBSEQUENT EVENTS
 
     The Company was acquired by High Speed Access Corp. in an exchange of stock
on April 3, 1998.

              UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS
 
     The unaudited combined pro forma statement of operation for the year ended
December 31, 1998 reflect the acquisitions of CATV.net, Inc. (CATV) and HSA
Network, Inc. (HSAN), as if the transactions occurred on January 1, 1998. Since
the pro forma financial statement which follow is based upon the financial
condition and operating results of CATV and HSAN during periods when they were
not under the control or management of High Speed Access Corp. (HSA), the
information presented may not be indicative of the results which would have
actually been obtained had the acquisitions been completed as of January 1, 1998
nor are they indicative of future financial or operating results. The unaudited
pro forma financial information does not give effect to any synergies that may
occur due to the integration of the companies. The combined pro forma statement
of operations should be read in conjunction with the historical audited
financial statement of HSA and the notes thereto, as well as the audited
historical financial statements of CATV and HSAN and the notes thereto included
elsewhere in this prospectus. The acquisitions have been accounted for by the
purchase method of accounting. A pro forma balance sheet as of December 31, 1998
has not been presented herein since both acquisitions were completed on April 3,
1998 and have been reflected in HSA's consolidated balance sheet as of December
31, 1998 appearing elsewhere herein.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Registrant's Amended and Restated Certificate of Incorporation to be in
effect upon the closing of this offering (collectively, the "Certificate")
provides that, except to the extent prohibited by the Delaware General
Corporation Law, as amended (the "DGCL"), the Registrant's directors shall not
be personally liable to the Registrant or its stockholders for monetary damages
for any breach of fiduciary duty as directors of the Registrant. Under the DGCL,
the directors have a fiduciary duty to the Registrant which is not eliminated by
this provision of the Certificate and, in appropriate circumstances, equitable
remedies such as injunctive or other forms of non-monetary relief will remain
available. In addition, each director will continue to be subject to liability
under the DGCL for breach of the director's duty of loyalty to the Registrant,
for acts or omissions which are found by a court of competent jurisdiction to be
not in good faith or involving intentional misconduct, for knowing violations of
law, for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by DGCL. This provision also does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws. The Registrant has obtained liability
insurance for its officers and directors.
 
     Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers. The Certificate provides
that the Registrant shall indemnify any person who was or is a party or is
threatened to be made a party to or becomes involved in any action, suit or
proceeding (whether civil, criminal, administrative or investigative) by reason
of the fact that such person is or was a director or officer of the Registrant,
or is or was serving at the request of the Registrant as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement reasonably
incurred by such person in connection with such action, suit or proceeding. The
DGCL provides further that the indemnification permitted thereunder shall not be
deemed exclusive of any other rights to which the directors and officers may be
entitled under the corporation's bylaws, any agreement, a vote of stockholders
or otherwise. The Registrant has entered into indemnification agreements with
each member of the Board of Directors providing for the indemnification of the
directors to the fullest extent authorized, permitted or allowed by Delaware
law.
 
                                      II-1
<PAGE>   127
 
     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The Registrant is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

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
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, 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 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 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 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 of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424 (b)(1) or (4), or 497(h)
under the Securities Act of 1933, shall be deemed to be part of this
registration statement as of the time it was declared effective.
 
     (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

the Shareholders Agreement and the Registration Rights Agreement, and any
Ancillary Agreement do not, and the consummation of the transactions
contemplated hereby and thereby will not, conflict with, or result in any

the terms and subject to the conditions contained herein.

                  NOW, THEREFORE, in consideration of the mutual covenants,
representations and warranties herein contained, and intending to be legally
bound, Company and Investor agree as follows:

         9.       Covenants of Company.  Company hereby covenants and agrees 
as follows:

                  9.1 Redemption Rights. At any time and from time to time from
and after September 1, 2003 but prior to the Company's completed firmly
underwritten initial public offering, Investor shall have the right and option
to sell to Company, and Company shall buy, Investor's shares of capital stock of
Company (the "Put") at a price per share (the "Put Purchase Price") equal to the
greater of (a) the initial purchase price per share of Investor's shares, plus
accrued but unpaid dividends through the date of the Put Closing (as defined
below), or (b) the fair market value per share (without application of any
discount for lack of marketability or minority position) as determined by a
qualified, independent appraiser experienced in valuation of shares of companies
similar to Company (the "Qualified Appraiser") acceptable to both Company and
Investor. If Investor and Company are unable to agree upon a Qualified
Appraiser, each of them shall separately designate a Qualified Appraiser. Such
Qualified Appraisers shall jointly designate a definitive Qualified Appraiser,
and such definitive Qualified Appraiser's determination shall be the fair market
value of Investor's shares of Company stock and shall be conclusive and binding
upon the parties. The fees and expenses of the definitive Qualified Appraiser
shall be borne equally by Company and Investor. The closing (the "Put Closing")
shall take place at a time and place mutually agreed upon by Investor and
Company on or before the 180th day after written notice of exercise of the Put
is given to Company by Investor, or if Investor and Company shall not agree on
the time and place, the Put Closing shall take place at the principal office of
Company in Louisville, Kentucky at 10:00 a.m. on the 180th day after written
notice of exercise is given, unless such day is a Saturday, Sunday or holiday,
in which case it shall occur on the next business day. The Put Purchase Price
shall be paid in cash at the Put Closing.

                  9.2 Reservation of Shares. On and after the Closing Date,
Company will reserve and keep reserved at all times sufficient Common Shares for
issuance upon conversion of the Series B Preferred Stock pursuant to Paragraph
B.4(a) of Article IV of the Company's Certificate of Incorporation. Immediately
prior to the occurrence of any event that would cause the number of Common
Shares into which the Series B Preferred Stock would be convertible to be
determined in accordance with Paragraph B.4(b) of Article IV of the Company's
Certificate of Incorporation, the Company shall take any and all actions
necessary to permit such conversion. Upon conversion of any shares of Series B
Preferred Stock, Company will promptly issue and deliver the Common Shares
required to be delivered.

                  9.3 Use of Proceeds. The proceeds from the sale of the Series
B Preferred Stock pursuant to this Agreement shall be used by Company for
working capital or for any other purpose approved by the Board of Directors of
the Company.

         Series A Preferred Stock or the Series B Preferred Stock;

                  [g] Repay any shareholder loans;

                  [h] Except as set forth in Section 9.4 of the Disclosure
         Letter, engage in any transactions with "affiliates", which for the

event or condition has occurred or exists, or, to the knowledge of Company, is

Financial Statements were prepared in accordance with Generally Accepted
Accounting Principles ("GAAP") (except for the omission of footnotes and other

aggregate, immaterial in amount); the balance sheet included in such Financial
Statements fairly presents the financial condition of Company and its
Subsidiaries as of October 31, 1998 and the statements of income included in

arrangements, guarantees, chattel mortgages or other security arrangements with
any bank, financial institution or other third party. Except as and to the
extent reflected and adequately reserved against in the Financial Statements or

         court of law;

                           [c] There is no labor strike, dispute, slowdown or
         stoppage actually pending or, to Company's best knowledge, threatened
         against Company or any Company Subsidiary;

         threatened, before the Equal Employment Opportunity Commission or any
         federal, state or local agency or court against Company or any Company
         Subsidiary. There are no pending governmental audits of the equal
         employment opportunity practices of Company or any Company Subsidiary
         and, to Company's best knowledge, no basis for any such claim exists.

                  5.18 Insurance. Company and each Company Subsidiary maintains
insurance policies, including property, casualty, liability and other insurance
with respect to its assets and business in amounts customary for similarly

Subsidiary is liable for any material retroactive premium adjustments with
respect to any of its insurance policies or bonds. All such policies and bonds
are legal, valid and enforceable and in full force and effect and neither
Company nor any Company Subsidiary is in breach or default (including with
respect to the payment of premiums or the giving of notices) and no event has
occurred which, with notice or the lapse of time, would constitute such a breach
or default, or permit termination, modification or acceleration under the policy
or received any notice of premium increases or cancellations with respect to any
of such policies and bonds. Company believes the amount and type of Company's
and each Company Subsidiary's insurance coverage is adequate for Company's and
each Company Subsidiary's business and is consistent with good business
practice.

other tax returns, tax information returns and reports ("Tax Returns") required

provisions for the payment of, all taxes, duties or assessments of any nature
whatsoever, interest payments, penalties and additions (whether or not reflected
in the returns as filed) due and payable (and/or properly accruable for all
periods ending on or before the date of this Agreement) to any city, county,
state, foreign country, the United States or any other taxing authority. There
are no security interests on any of the assets of Company or any Company
Subsidiary that arise in connection with any failure (or alleged failure) to pay
any tax. Company and each Company Subsidiary has withheld and paid all taxes
required to have been withheld and paid in connection with amounts paid or owing
to any employee, independent contractor, creditor, stockholder or other third
party.

with which Company or any Company Subsidiary has a business relationship, or any
firm or corporation that competes with Company or any Company Subsidiary, except
that employees, stockholders, and officers of Company and members of their

the Amended Certificate, including, without limitation, the rights of the
Preferred Stock upon liquidation and dissolution, at any time and from time to
time from and after November 25, 2003 but prior to a Qualified Public Offering
(as defined in Section 10 of this Agreement), Investor shall have the right and
option to sell to Company, and Company shall buy, Investor's shares of Series B
Preferred Stock and any Common Shares into which such Series B Preferred Stock
shall have been converted (the "Put") at a price per share (the "Put Purchase
Price") equal to the greater of (a) $2.50 per share, plus accrued but unpaid
dividends, whether or not declared, through the date of the Put Closing (as
defined below), or (b) the fair market value per share as of the date Investor's
written notice of exercise of the Put is given to Company (without application
of any discount for lack of marketabili ty or minority position) as determined
by a qualified, independent appraiser experienced in the valuation of shares of
companies similar to Company (the "Qualified Appraiser") acceptable to both
Company and Investor. If Investor and Company are unable to agree upon a
Qualified Appraiser, each of them shall separately designate a Qualified
Appraiser. Such Qualified Appraisers shall jointly designate a definitive
Qualified Appraiser, and such definitive Qualified Appraiser's determination of
such fair market value of Investor's shares of Company stock shall be conclusive
and binding upon the parties. The fees and expenses of the definitive Qualified
Appraiser shall be borne equally by Company and Investor. The closing (the "Put
Closing") shall take place at a time and place mutually agreed upon by Investor
and Company on or before the 120th day after written notice of exercise of the
Put is given to Company by Investor, or if Investor and Company shall not agree
on the time and place, the Put Closing shall take place at the principal office
of Company in Louisville, Kentucky at 10:00 a.m. on the 120th day after written
notice of exercise is given, unless such day is a Saturday, Sunday or holiday,
in which case it shall occur on the next business day. The Put Purchase Price
shall be paid in cash at the Put Closing. Notwithstanding the provisions of the

                                       14

first sentence of this Section 9.1, in the event that any person or entity
exercises a put right with respect to any equity securities of Company on a date
earlier than November 25, 2003, the right of Investor to exercise the Put shall
automatically be accelerated to such earlier date.

                  9.2 Reservation of Shares. On and after the Closing Date,
Company will reserve and keep reserved at all times sufficient Common Shares for
issuance upon conversion of the Series B Preferred Stock. Immediately prior to
the occurrence of any event that would cause the number of Common Shares or type
of securities into which the Series B Preferred Stock would be convertible to be
adjusted, Company shall take any and all actions necessary to permit such
conversion. Upon conversion of any shares of Series B Preferred Stock, Company
will promptly issue and deliver the Common Shares required to be delivered.

                  9.3 Financial Reporting. For periods commencing on or after
the Closing Date, Company shall deliver or cause to be delivered to Investor, on
a monthly basis, monthly and year-to-date balance sheets and income and cash
flow statements (each as compared to budget and the comparable prior year
period), and a monthly written summary of operations. Such monthly reports shall
be provided on or before thirty (30) days following the end of each month. Not
later than thirty (30) days prior to the end of each fiscal year, Company shall
provide a business plan and projections for the next fiscal year. Annual audits
of the Company's financial statements for periods commencing on or after January

accounting firm approved by the audit committee of Company's Board of Directors,

Company, subject to the requirements of Section 9.5 hereof.

                  Series C Preferred Stock purchased subsequent to the Closing,

                  not thereafter require the consent of holders of the majority
                  of shares of any class or series of Preferred Stock controlled

                      SERIES C CONVERTIBLE PREFERRED STOCK
                               PURCHASE AGREEMENT


                  THIS SERIES C CONVERTIBLE PREFERRED STOCK PURCHASE AGREE MENT
("Agreement") is made and entered into as of the 25th day of November, 1998, by
and between HIGH SPEED ACCESS CORP., a Delaware corporation ("Company"), and
VULCAN VENTURES, INCORPORATED, a Washington corporation ("Investor");


                                   WITNESSETH:

                  WHEREAS, Company desires to sell and issue, and Investor
desires to purchase and acquire, 2,500,000 shares of Company's authorized but
unissued Series C Convertible Preferred Stock ("Series C Preferred Stock") and
Company desires to offer to Investor and Investor desires to have the
opportunity to purchase an additional 2,500,000 shares of Series C Preferred
Stock, all upon the terms and subject to the conditions contained herein;

                  NOW, THEREFORE, in consideration of the mutual covenants,
representations and warranties herein contained, and intending to be legally
bound, Company and Investor agree as follows:

         1.       Sale and Issuance of Series C Convertible Preferred Stock.

                  1.1 Company shall adopt and file with the Secretary of State
of the State of Delaware on or before the Closing (as defined below) a
Certificate of Amendment to the Certificate of Incorporation of Company in the
form attached hereto as Exhibit A (the "Certificate of Amendment"). The Series C
Preferred Stock will have the rights, preferences, privileges and restrictions
set forth in the Certificate of Amendment.

                  1.2 Subject to the terms and conditions of this Agreement, at
any time after the Closing, but on or before the second anniversary of the date
hereof, at Company's option, evidenced by a resolution of its Board of Directors
and upon ten (10) days prior written notice given by Company to Investor (unless
waived in writing by Investor) (the "Post Closing Capital Call"), Investor
agrees to purchase from Company, and Company agrees to sell, issue and deliver
to Investor, 2,500,000 shares of Series C Preferred Stock at a price of Five
Dollars ($5.00) per share, for an aggregate purchase price of Twelve Million
Five Hundred Thousand Dollars ($12,500,000). Investor shall be, under no
circumstances, obligated to purchase any shares of Series C Preferred Stock
under this Agreement, and Company shall refrain from making the Post Closing
Capital Call, if (A) Company has not performed in all material respects with all
of the financial performance milestones of Company as set forth in Company's
Business Plan as of October, 1998 attached to this Agreement as Exhibit B (the
"Business Plan") or (B) the Company's Board of Directors has failed to
reasonably demonstrate to Investor that Company is in need of cash proceeds from
the sale of the Series C Preferred Stock subject to the Post Closing Capital
Call, and such need is anticipated in the Business Plan and, in addition, the
proceeds received pursuant to the Post Closing Capital Call shall


<PAGE>   3




not exceed the amount of cash capital required by Company during the immediately
succeeding twelve (12) month period after the Post Closing Capital Call.
Investor may, at its option, [i] prepay the purchase price for all of the shares
of Series C Preferred Stock at any time prior to Company making the Post Closing
Capital Call with respect thereto by delivering the purchase price for the
shares so purchased by wire transfer of immediately available funds to Company's
account, and [ii] upon any liquidation, dissolution, or winding up of Company,
purchase all of the shares of Series C Preferred Stock not theretofore purchased
by Investor pursuant to this Agreement by delivering the purchase price for the
shares so purchased by wire transfer of immediately available funds to Company's
account. Company shall provide Investor with 45 days prior written notice of any
such liquidation, dissolution or winding up. For purposes of [ii] above, any
merger or consolidation of Company with or into any other corporation or entity
or sale of all or substantially all of the assets of Company shall be deemed a
liquidation, dissolution or winding up of Company, except for a merger or
consolidation or sale of all or substantially all the assets or outstanding
capital stock of Company in which the shareholders of Company immediately prior
thereto shall, immediately thereafter, hold as a group the right to cast all of
the votes of all holders of voting securities of the resulting or surviving
corporation or entity on any matter on which any such holders of voting
securities shall be entitled to vote.

                  1.3 [a] At any time after the Post Closing Capital Call shall
have been made, but on or before the second anniversary of the date hereof,
Company shall offer Investor, not more than six (6) months and not less than
five (5) months prior to Company being in need of further cash capital, the
right to purchase 2,500,000 additional shares of Series C Preferred Stock
("Additional Series C Shares") at a purchase price of $5.00 per share or such
lesser price as the Board of Directors of Company shall determine to be the fair
value of such Additional Series C Shares, which price will also be the price
Company will otherwise sell such securities to other purchasers (the "Stated
Value"). Investor shall have sixty (60) days after having received notice of
such right from Company to exercise its right to purchase all of the Additional
Series C Shares by delivering written notice of its intention to purchase such
Shares to Company. If Investor declines to purchase all of the Additional Series
C Shares and Company thereafter offers to sell the Additional Series C shares
within the next succeeding six (6) month period at a purchase price less than
the Stated Value, Investor shall have ten (10) days from the date of receiving
delivery of written notice from Company of the offer at such lower price to
purchase all such Additional Series C Shares at such lower price. Investor shall
exercise its purchase of such Additional Series C Shares by delivering a written
notice to Company. If all of the Additional Series C Shares are not fully
subscribed by Investor within such sixty (60) day or ten (10) day period, as the
case may be, the Additional Series C Shares may be offered for sale by Company
in accordance with the subscription rights set forth in Section 5.A of the
Shareholders Agreement (as defined in Section 3.1 below).

                      [b] At any time after the date hereof, Investor shall 
have the right, at its election, to purchase any number of Series C Shares which
have not, as of such date, been issued at a purchase price of $5.00 per share.
Investor may elect to exercise its right to purchase such Series C Shares
pursuant to this Section 1.3[b] by delivering a written notice to Company and
the purchase of the Additional Series C Shares shall be consummated within ten
(10) days after delivery thereof.

                  1.4 The parties to this Agreement acknowledge that in
connection with the Post Closing Capital Call or any purchase of Additional
Series C Shares pursuant to Section 1.3 hereof, the parties may be required to
file Notification and Report Forms under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), with the Federal Trade
Commission and the Antitrust Division of the United States Department of
Justice, or otherwise comply with the provisions of the HSR Act. Each party
agrees that in connection with the Post Closing Capital Call it will act in good
faith to analyze and evaluate its obligations under the HSR Act. In the event
either party reasonably determines that it is required to make any filing under
the HSR Act in connection with the Post Closing Capital Call, it will so notify
the other party and the other party will reasonably cooperate with the filing
party, each party will expeditiously comply with its filing requirements and
shall use its best efforts to obtain an early termination of the applicable
waiting period. Notwithstanding any other provision of this Agreement, the time
period during which the Post Closing Capital Call or any purchase of Additional
Series C Shares pursuant to Section 1.3 hereof, must be made shall be tolled for
the duration of any applicable HSR Act waiting period (and any related
investigative period imposed by the Federal Trade Commission with respect to any
such filing).

         2. Closing. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at 10:00 a.m. on November 25, 1998,
at the offices of Wyatt, Tarrant & Combs, 2800 Citizens Plaza, Louisville,
Kentucky, or at such other time, date, or place as shall be mutually agreed upon
by the parties hereto in writing (the "Closing Date"). The Post Closing Capital
Call and the purchase of Additional Series C Shares, if any, shall be
consummated as contemplated by Section 1.2 and Section 1.3 above, respectively,
by delivery of certificates representing the shares of Series C Preferred Stock
Investor is purchasing against payment of the purchase price therefor in
immediately available funds.

         3.       Closing Items.

<PAGE>   6

representations and warranties given at the Closing and there is not a material
adverse change in the financial performance of Company relative to the financial
performance of Company as set forth in the Business Plan. Investor's obligation
to purchase 2,500,000 shares of Series C Preferred Stock pursuant to the Post
Closing Capital Call made in accordance with Section 1.2 shall otherwise be
unconditional. All payments by Investor shall be made by wire transfer of
immediately available funds to the account specified by Company. In the event
that payment has not been made within fifteen (15) days of the date of the Post
Closing Capital Call as set forth in a written notice sent by Company to
Investor by facsimile transmission and overnight delivery, interest on the
amount due shall accrue and be payable to Company at the rate of 10% per annum.
In addition, in the event such payment has not been made within forty-five (45)
days of the date of the Post Closing Capital Call, Company shall have the option
for ninety (90) days after expiration of such forty-five (45) day period (the
"Call") to purchase any or all of the shares of stock of Company owned by
Investor at $5.00 per share, without interest (the "Call Purchase Price"). The
closing (the "Call Closing") shall take place at a time and place mutually
agreed upon by Investor and Company on or before the 120th day after written
notice of exercise of the Call is given by Company to Investor, or if Investor
and Company shall not agree on the time and place, the Call Closing shall take
place at the principal office of Company in Louisville, Kentucky at 10:00 a.m.
on the 120th day after written notice of exercise is given, unless such day is a
Saturday, Sunday or holiday, in which case it shall occur on the next business
day. Notwithstanding the foregoing, Company may unilaterally withdraw its
exercise of the Call hereunder without obligation to Investor at any time within
sixty (60) days after exercise of such Call by giving Investor written notice of
such withdrawal.

         4. Further Assurances. Each party shall execute such additional
documents and take such other actions as the other party may reasonably request
to consummate the transactions contemplated hereby, and otherwise as may be
necessary to effectively carry out the terms and provisions of this Agreement.

authority to own, lease and operate its properties and to carry on its business
as now being conducted and as presently proposed to be conducted. Company and
each Company Subsidiary is duly qualified and is authorized to transact business

hereafter in effect relating to creditors rights generally or (ii) general
principals of equity (regardless of whether an enforceability is considered in a
proceeding at law or in equity).

                  5.5 No Conflict. The execution and delivery of this Agreement
and any Ancillary Agreement do not, and the consummation of the transactions
contemplated hereby and thereby will not, conflict with, or result in any

or otherwise, which are not fully reflected or reserved against in the Financial

money, indebtedness by way of lease-purchase arrangements, guarantees, chattel
mortgages or other security arrangements with any bank, financial institution or
other third party. Except as and to the extent reflected and adequately reserved
against in the Financial Statements or incurred in the ordinary course of
business since the date of the Financial Statements, as of the Closing Date,

Company Subsidiary asserting that Company's or any Company Subsidiary's use of
any intellectual property infringes the rights of any third party or otherwise
contesting Company's and each Company Subsidiary's rights with respect to any
intellectual property, and there is no basis for such assertion or contest. To
Company's best knowledge, no third party is infringing on Company's or any
Company Subsidiary's rights with respect to its intellectual property.

similar laws now or hereafter in effect relating to creditors rights generally
or (ii) general principals of equity (regardless of whether an enforceability is
considered in a proceeding at law or in equity).

                  6.2 Investment Representations. Investor is acquiring the
Series C Preferred Stock and the Common Shares issuable upon conversion thereof
(collectively the "Securities") solely for its own account as principal, for
investment purposes only and not with a view to resale or distribution thereof
in whole or in part, and Investor has no present intention of selling, granting
any participation in, or otherwise distributing the Securities. No other person
has a direct or indirect beneficial interest in the Securities to be acquired by
Investor hereunder and Investor does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer or grant
participation to any third person, with respect to any of the Securities.

                  6.3 Accredited Investor; Residence. Investor is domiciled in
the State of Washington and is an "accredited investor" as such term is defined
under Regulation D of the Securities Act. Paul G. Allen owns beneficially and of
record more than fifty percent (50%) of the outstanding voting securities of
Investor.

                  6.4 Receipt of Information; Restricted Securities. Subject to
the Registration Rights Agreement, Investor acknowledges that the Securities are
not being and will not be registered under the Securities Act or the securities
laws of any other jurisdiction in reliance on exemptions thereunder. The
Securities have not been and will not be approved or disapproved by the
Securities and Exchange Commission or any other governmental authority or agency
of any jurisdiction. Investor represents that Investor has had an opportunity to
ask questions and receive answers from Company regarding the terms and
conditions of the offering of the Series C Preferred Stock and the business,
properties, prospects, and financial condition of Company and to obtain
additional information (to the extent Company possessed such information or
could acquire it without unreasonable effort or expense) necessary to verify the
accuracy of any information furnished to Investor or to which Investor had
access. Investor's representations under this Section 6, however, shall not
limit or modify the representations and warranties of Company in Section 5 of
this Agreement or the right of Investor to rely thereon.

                  6.5 Investment Experience. Investor is experienced in
evaluating and investing in private placement transactions of securities of
companies in a similar stage or development, and acknowledges that it is able to
fend for itself, can bear the economic risk of its investment, and has such
knowledge and experience in financial and business matters that it is capable of
evaluating the merits and risks of the investment in the Series C Preferred
Stock.

         7. Survival of Representations and Warranties. All representations and
warranties contained in this Agreement by either party to this Agreement and any
certificate or other instrument delivered by or on behalf of either party
pursuant to this Agreement shall be continuous and shall survive the Closing and
the issuance of all shares of Company's capital stock as contemplated hereunder.
Each party shall have the right to rely on each other party's representations
and warranties made herein, notwithstanding any investigation conducted by such
party.

         8.       Indemnification.

                  8.1 Indemnification by Company. Company shall indemnify and
reimburse Investor for any and all claims, losses, liabilities, damages
(including, without limitation, fines, penalties, and criminal or civil
judgments and settlements), costs (including, without limitation, court costs)
and expenses (including, without limitation, reasonable attorneys' and
accountants' fees) suffered or incurred by Investor, and any successors or
assigns thereto as a result of, or with respect to:

                           [a] any breach or inaccuracy of any representation or
         warranty of Company set forth in Section 5 hereof or in any exhibit,
         schedule or annex to this Agreement;
                           [b] any breach of or noncompliance by Company with
         any covenant or agreement of Company contained in this Agreement; and

                           [c] any and all actions, suits, proceedings, claims,
         demands, assessments and judgments incident to any of the foregoing.

                  8.2 Limitation on Investor's Liability. The liability of
Investor to Company with respect to any claims arising from the performance or
breach of this Agreement by Investor shall be limited to the amount of the
aggregate purchase price for the Series C Preferred Stock purchased or to be
purchased by Investor under this Agreement.

         9. Covenants of Company. Company hereby covenants and agrees as
follows:

                  9.1 Redemption Rights. Subject to the terms and provisions of
the Amended Certificate, including without limitation, the rights of the
Preferred Stock upon liquidation and dissolution, at any time and from time to
time from and after November 25, 2003, but prior to a Qualified Public Offering
(as defined in Section 9.5 of this Agreement), Investor shall have the right and
option to sell to Company, and Company shall buy, Investor's shares of Series C
Preferred Stock and any Common Shares into which such Series C Preferred Stock
shall have been converted (the "Put") at a price per share (the "Put Purchase
Price") equal to the greater of (a) $5.00 per share, plus accrued but unpaid
dividends, whether or not declared, through the date of the Put Closing (as
defined below), or (b) the fair market value per share as of the date Investor's
written notice of exercise of the Put is given to Company (without application
of any discount for lack of marketabili ty or minority position) as determined
by a qualified, independent appraiser experienced in the valuation of shares of
companies similar to Company (the "Qualified Appraiser") acceptable to both
Company and Investor. If Investor and Company are unable to agree upon a
Qualified Appraiser, each of them shall separately designate a Qualified
Appraiser. Such Qualified Appraisers shall jointly designate a definitive
Qualified Appraiser, and such definitive Qualified Appraiser's determination of
such fair market value of Investor's shares of Company stock shall be conclusive
and binding upon the parties. The fees and expenses of the definitive Qualified
Appraiser shall be borne equally by Company and Investor. The closing (the "Put
Closing") shall take place at a time and place mutually agreed upon by Investor
and Company on or before the 120th day after written

                                       16
<PAGE>   18




notice of exercise of the Put is given to Company by Investor, or if Investor
and Company shall not agree on the time and place, the Put Closing shall take
place at the principal office of Company in Louisville, Kentucky at 10:00 a.m.
on the 120th day after written notice of exercise is given, unless such day is a
Saturday, Sunday or holiday, in which case it shall occur on the next business
day. The Put Purchase Price shall be paid in cash at the Put Closing.
Notwithstanding the provisions of the first sentence of this Section 9.1, in the
event that any person or entity exercises a put right with respect to any equity
securities of Company on a date earlier than November 25, 2003, the right of
Investor to exercise the Put shall automatically be accelerated to such earlier
date.

                  9.2 Reservation of Shares. On and after the Closing Date,
Company will reserve and keep reserved at all times sufficient Common Shares for
issuance upon conversion of the Series C Preferred Stock. Immediately prior to
the occurrence of any event that would cause the number of Common Shares or type
of securities into which the Series C Preferred Stock would be convertible to be
adjusted, the Company shall take any and all actions necessary to permit such
conversion. Upon conversion of any shares of Series C Preferred Stock, Company
will promptly issue and deliver the Common Shares required to be delivered.

                  9.3 Financial Reporting. For periods commencing on or after
the Closing Date, Company shall deliver or cause to be delivered to Investor, on
a monthly basis, monthly and year-to-date balance sheets and income and cash
flow statements (each as compared to budget and the comparable prior year
period), and a monthly written summary of operations. Such monthly reports shall
be provided on or before thirty (30) days following the end of each month. Not
later than thirty (30) days prior to the end of each fiscal year, Company shall
provide a business plan and projections for the next fiscal year. Annual audits
of the Company's financial statements for periods commencing on or after January
1, 1998 shall be performed by PriceWaterhouseCoopers LLP, or another independent
accounting firm approved by the audit committee of Company's Board of Directors,
and copies thereof shall be delivered to Investor on or before the 120th day
following the end of Company's fiscal year.

                  9.4 Use of Proceeds. The proceeds from the sale of the Series
C Preferred Stock pursuant to this Agreement shall be used by Company for
working capital or for any other purpose approved by the Board of Directors of
Company, subject to the requirements of Section 9.5 hereof.

                  9.5      Prohibited Matters.

                           [a] From and after the date hereof, Company shall

                  million, or engage in more than one of any of such

                  materially and adversely affect the holders of the Preferred
                  Stock, it being acknowledged by Company and Investor that a
                  Qualified Public Offering shall not be deemed to materially
                  and adversely affect the Preferred Stock.

         For purposes of this Agreement, a "Qualified Public Offering" shall
         mean an underwritten public offering of Common Shares, initiated by
         resolution of its Board of Directors, at a per share price of at least
         $7.50 (as proportionately and appropriately adjusted to reflect any
         subdivision, reverse split or recapitalization of the Common Shares
         after the date hereof) and aggregate gross proceeds of not less than
         $50 million to Company, which has been made pursuant to a registration
         statement filed with the Securities and Exchange Commission under the
         Securities Act.

                           [b] Notwithstanding the provisions of Section 9.5[a]
above:

                                    [i] In the event there has been one or more
                  transfers by Broadband (defined as Broadband Solutions, LLC
                  ("Broadband I") and Broadband Solutions II, LLC ("Broadband
                  II") considered together) of more than, in the aggregate, 30%
                  of the total number of shares of Preferred Stock owned by
                  Broadband immediately succeeding the Closing, together with
                  any Series C Preferred Stock purchased subsequent to the
                  Closing, to one or more non-Affiliates of Broadband I or
                  Broadband II, then Company shall not thereafter require the
                  consent of the holders of the majority of shares of any class
                  or series of Preferred Stock controlled by Broadband to effect
                  any of the "prohibited matters" referred to in Section 9.5[a].
                  For purposes of this paragraph, any transfer by Broadband I or
                  Broadband II to River Cities Capital Fund ("River Cities")
                  shall not constitute a transfer to a non-Affiliate of
                  Broadband I or Broadband II if River Cities grants an
                  irrevocable proxy to Broadband to vote on all matters, but any
                  subsequent transfer by River Cities (other than to its
                  partners and so long as they grant a proxy to Broadband) shall
                  constitute a transfer to a non-Affiliate, unless such
                  subsequent transferee is an Affiliate of Broadband.

                                    [ii] In the event that there has been one or
                  more transfers by Investor of more than, in the aggregate, 30%
                  of the total number of shares of Preferred Stock owned by
                  Investor immediately succeeding the Closing, together with any
                  Series C Preferred Stock purchased subsequent to the Closing,
                  to one or more non-Affiliates of Investor, then Company shall
                  not thereafter require the consent of holders of the majority
                  of shares of any class or series of Preferred Stock controlled
                  by Investor to effect any of the "prohibited matters" referred
                  to in Section 9.5[a].

upon the terms and conditions set forth in this Warrant but in no event later
than the Effective Date, and purchase during the Exercise Period, for Subscribed
Shares in any amount equal to the number of Homes Passed (in excess of 750,000)
in Cable Systems which the Operator has designated as additional Committed
Systems (on a one (1) Warrant Share per each Home Passed basis), in accordance
with Section 2.2 of the Network Services Agreement; provided that:

                           (1) the number of Subscribed Shares issuable under
         this Warrant, to the extent of the number of Homes Passed in an
         additional Committed System designated under Section 2.2 of the Network
         Agreement (on a one (1) Warrant Share per Home Passed basis), will be

<PAGE>   5
         with Homes Passed in another Committed System(s)or additional Committed
         Systems, provided, that Subscribed Shares issuable under this Warrant
         will not be cancelled or deemed forfeited if Operator terminates any of
         HSAC's exclusive rights to provision HSAC Services in any Committed
         Systems as provided for or permitted under the Systems Access Agreement
         or the Network Services Agreement; and provided further, that as of

         under the Network Agreement, the number of outstanding Class A Warrants
         and Class B Warrants, and the number of shares theretofore issued upon
         exercise of this Warrant and the Class B Warrant. If such
         reconciliation reveals that the total number of Homes Passed in all
         Committed Systems (in excess of 750,000) under the Network Agreement
         (after adding back in Homes Passed in Committed Systems and additional
         Committed Systems withdrawn from the Network Agreement pursuant to
         Sections 18.1, 18.2, 18.3 and/or 18.6 thereof) is different than the
         total number of all outstanding Class A Warrants and Class B Warrants
         and Warrant Shares, then the number of Class A Warrants and/or Class B
         Warrants will be adjusted upward or downward, as the case may be. If
         the number of unexercised Class A Warrants and/or Class B Warrants then
         held by Vulcan is insufficient to cover any shortfall, then Vulcan (or
         its permitted transferee) shall return to HSAC a number of Warrant
         Shares necessary to meet such shortfall, and HSAC shall refund to
         Vulcan the exercise price paid by Vulcan for such returned Warrant
         Shares;

                           (2) the inspection and commissioning procedures set
         forth in Section 2.3 of the Network Agreement have been satisfied, and

                           (3) at no time may the number of such Subscribed
         Shares/Warrant Shares exceed, in the aggregate, the Maximum Number of
         Warrant Shares.

                  (b) To exercise this Warrant an authorized officer of Holder
(or its permitted transferee) shall, during the Exercise Period, on the day the
Holder wishes to exercise this Warrant (the "Exercise Date"):

                           (1) Complete and certify the Subscription Form by
         designating the number of Subscribed Shares to which the Holder (or
         such permitted transferee) is entitled to exercise and wishes to
         exercise pursuant to such Subscription Form and Section 1 hereof (which
         may be less than or equal to the Maximum Number of Warrant Shares);

                           (2) Surrender this Warrant to the Secretary at the
         Company's Office, and

                           (3) Upon the surrender of this Warrant to the
         Secretary, deliver to the Secretary at the Company's Office a certified
         or cashier's check payable to the Company's order in an amount equal to
         (i) the number of Subscribed Shares, times (ii) the Exercise Price.

In the event the Company has completed a Qualified Public Offering, the Holder
may at its option, in lieu of tendering a certified or cashier's check as
provided in subparagraph (3) above, exercise this Warrant

                                       5
<PAGE>   6
by submitting, during normal business hours, a duly executed exercise notice
marked to reflect "Net Issue Exercise," and specifying the number of shares of
Warrant Shares to be exercised. Upon a Net Issue Exercise, Holder shall be
entitled to receive Warrant Shares equal to the value of this Warrant (or the
portion thereof being exercised by Net Issue Exercise) by surrender of this
Warrant to the Company together with notice of such election, in which event the
Company shall issue to Holder a number of shares of the Company's Common Stock
computed as of the date of surrender of this Warrant to the Company using the
following formula:

                           X = Y x (A-B)
                               _________
                                    A

         Where    X = the number of Warrant Shares to be issued to Holder;

                  Y = the number of Warrant Shares purchasable under this
                       Warrant (at the date of such calculation).

                  A = the Current Market Price of one share of the
                      Company's Common Stock (at the date of such
                      calculation);

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

As used above, "Current Market Price" means, if the Company's Common Stock is
traded on a national securities exchange, the NASDAQ National Market System or
the over-the-counter market, the average of the last reported price over the
five (5) trading days immediately preceding the date of valuation at which the
Common Stock has traded on such national securities exchange, the NASDAQ
National Market System or the average of the bid and asked prices on the
over-the-counter market on the date of valuation.

                  (c) Notwithstanding any delay in the actual issuance of a
Stock Certificate or Receipt pursuant to Section 4 hereof, the Warrant Shares
shall be deemed issued for all purposes as of the opening of business on the
Exercise Date subject to the provisions of Section 6.1.3 of the Systems Access
Agreement, and the Holder shall for all purposes be deemed to be the holder of
record of the Subscribed Shares to which the Receipt or the Stock Certificate
pertains.

         4. Issuance of Certificate for Subscribed Shares. Upon the Holder's
exercise of this Warrant in accordance with Section 3, the Company shall deliver
to the Holder:

                  (a) If the Subscribed Shares constitutes the Maximum Number of
Warrant Shares (and as the Company chooses), either (1) a Stock Certificate, or
(2) a Receipt.

                  (b) If the Subscribed Shares constitute less than the Maximum
Number of Warrant Shares (and as the Company chooses), either

                                       6
<PAGE>   7
                           (1) (i) a Stock Certificate, together with (ii) a new
         Securities Purchase Warrant, containing the same terms and conditions
         as this Warrant, evidencing the Holder's continued right to subscribe
         (during the Exercise Period) for the remainder of the Maximum Number of
         Warrant Shares; or

                           (2) (i) a Receipt, together with (ii) a new
         Securities Purchase Warrant, containing the same terms and conditions
         as this Warrant, evidencing the Holder's continued right to subscribe
         (during the Exercise Period) for the remainder of the Maximum Number of
         Warrant Shares.

         5. Transfer of Warrant.

                  (a) This Warrant shall be registered on the books of the
Company, which shall be kept at its Office for that purpose, and shall be
transferable in whole or in part but only on such books, by the Holder (or
Holder's duly authorized representative) in person or by duly authorized
attorney substantially in the form of Exhibit B hereof, and only in compliance
with paragraph (b) below. The Company may issue appropriate stop orders to its
Secretary or transfer agent to prevent a transfer in violation of this Section 5
and Section 7.

                  (b) The Holder may transfer this Warrant to any Person or
Persons at any time during the Warrant Period by completing and signing the
transfer form (the "Transfer Form") in the form of transfer form attached as
Exhibit B to this Warrant; provided, however, that without the prior written
consent of the Company, this Warrant and all rights hereunder may be transferred
only (i) to an Affiliate, or (ii) in accordance with the requirements of Section
8 hereof and pursuant to the registration of this Warrant or the Warrant Shares
under the Securities Laws (except as otherwise limited by any applicable
shareholders buy-sell, registration rights, or voting agreements binding upon
the Holder) or subsequent to eighteen (18) months from the Effective Date hereof
an exemption under Rule 144 or other exemption from such registration. If at
least fifteen (15) working days before the end of the Exercise Period the Holder
completes and signs the Transfer Form and surrenders this Warrant to the
Secretary at the Company's Office, the Company shall, within ten (10) working
days after this Warrant's surrender, issue to the transferee or transferees
identified on the completed Transfer Form one or more new Securities Purchase
Warrants (containing the same terms and conditions as this Warrant) evidencing
the transferee's or transferees' right or rights to subscribe (during the
Exercise Period) for all or part of the Warrant Shares.

         6. Anti-Dilution. The maximum number of Warrant Shares and the Exercise
Price for any Subscribed Shares shall be adjusted if during the Exercise Period,
but before the Holder's exercise of this Warrant:

         (a) Issues of Shares. The Company shall issue any of its Common Shares
for a consideration per share which is less than the Exercise Price in effect
immediately prior to such issuance (other than shares issued to employees,
officers, directors or consultants of the Company pursuant to

                                       7
<PAGE>   8
option plans approved by the Board of Directors of the Company), the Exercise
Price shall be reduced to such lower price. For purposes of this subparagraph
[a], the following clauses shall also be applicable:

                           [1] Convertible Securities, Options and Rights. If,
         at any time the Company shall issue or sell any rights, options,
         warrants or other securities entitling the holders thereof to purchase
         Common Shares or convert such securities into Common Shares at a price
         per share (determined by dividing (i) the total amount, if any,
         received or receivable by the Company in consideration of the issuance
         or sale of such rights, options, warrants or other securities plus the
         total amount if any, payable to the Company upon exercise or conversion
         thereof (the "Total Consideration") by (ii) the number of additional
         Common Shares issuable upon exercise or conversion of such securities)
         which is less than the Exercise Price in effect on the date of such
         issuance or sale, the Exercise Price price shall be adjusted as of the
         date of such issuance or sale so that the same shall equal the price
         determined by dividing (i) the sum of (A) the number of Common Shares
         outstanding on the date of such issuance or sale multiplied by the
         Exercise Price in effect immediately prior thereto plus (B) the Total
         Consideration by (ii) the number of Common Shares outstanding on the
         date of such issuance or sale plus the maximum number of additional
         Common Shares issuable upon exercise or conversion of such securities.
         Simultaneously with all adjustments to the number and/or kind of
         securities, property and cash to be issued in connection with any such
         issuance, sale or conversion, the Exercise Price will also be
         appropriately adjusted so that at all times the holder hereof will not
         pay more than the aggregate purchase price to exercise this Warrant in
         full immediately after such adjustment as such holder had to pay
         immediately prior to such adjustment.

                           [2] Distributions, Share Dividends and Splits.

                                    (i) In case the Company declares a dividend
                  or other distribution payable in Common Shares or subdivides
                  its Common Shares into a greater number of Common Shares, the
                  Exercise Price in effect immediately prior to such declaration
                  or subdivision shall be proportionately decreased and the
                  number and kind of shares purchasable upon exercise of this
                  Warrant shall be adjusted so that the holders thereof shall be
                  entitled to receive the kind and number of shares or the other
                  securities of the Company (such other securities thereafter
                  enjoying the rights of shares) that the Holder would have
                  owned or have been entitled to receive after the happening of
                  any of the events described in this paragraph [2] had the
                  Warrant Shares been issued immediately prior to the happening
                  of such event or any record date with respect thereto.

                                    (ii) In case the Company shall distribute to
                  the holders of Common Shares (i) securities, (ii) property,
                  other than cash, or (iii) cash, without fair payment therefor,
                  then, and in each such case, the Holder upon exercise hereof
                  shall be entitled to receive such securities, property and
                  cash which such Holder would have received had such Holder
                  been the holder of record of the Common Shares, subject,
                  however, to such Holder agreeing to any conditions to such
                  distribution as were required of all other holders of Common
                  Shares in connection with such distribution.

                                       8
<PAGE>   9
                                    (iii) If the securities to be distributed by
                  the Company to persons other than holders of this Warrant
                  involve rights, warrants, options, or any other form of
                  convertible securities and the right to exercise or convert
                  such securities would expire in accordance with its terms
                  prior to the exercise of this Warrant, and without the
                  exchange of any such rights, warrants or options, then the
                  terms of such securities shall provide that such exercise or
                  convertibility shall remain in effect until thirty (30) days
                  after the date the holder of this Warrant becomes a holder of
                  Common Shares pursuant to the conversion thereof.

                           An adjustment made pursuant to this paragraph [2]
                  shall become effective immediately after the record date in
                  the case of a dividend or distribution and shall become
                  immediately effective after the effective date in the case of
                  a subdivision, combination or issuance. If, as a result of an
                  adjustment made pursuant to this paragraph B, the Holder after
                  exercise shall become entitled to receive shares of two or
                  more classes of capital or Common Shares and any other class
                  of capital stock of the Company, the Board of Directors of the
                  Company (whose determination shall be conclusive and shall be
                  described in a written notice to the Holder promptly after
                  such adjustment) shall determine the allocation of the
                  adjusted Exercise Price between or among shares of such
                  classes of capital stock or Common Shares and such other
                  classes of capital stock.

                           [3] Consideration. In case the Company shall issue
                  its Common Shares for a consideration wholly or partly other
                  than cash, the amount of the consideration other than cash
                  received by the Company shall be deemed to be the lesser of
                  (i) the fair market value on the issue date of the Common
                  Shares so issued by the Company, as determined in good faith
                  by the Board of Directors of the Company, less any cash
                  consideration, or (ii) the fair market value of such
                  consideration as determined in good faith by the Board of
                  Directors of the Company.

                           [4] Record Dates. In case the Company shall take a
                  record of the holders of its Common Shares for the purpose of
                  determining Holders entitled (i) to receive a dividend or
                  other distribution payable in Common Shares, or (ii) to
                  subscribe for or purchase Common Shares, then such record date
                  shall be deemed to be the date of the issue or sale of the
                  Common Shares issued upon the declaration of such dividend or
                  the making of such distribution or deemed to have been issued
                  upon the granting of such right of subscription or purchase,
                  as the case may be.

                           [5] Treasury Shares. The number of Common Shares
                  outstanding at any given time shall not include shares owned
                  or held by or for the account of the Company in its treasury,
                  and the disposition of any such shares so owned or held shall
                  be considered an issue of Common Shares.

                                       9
<PAGE>   10
                           [6] Minimum Exercise Price. In no case shall the
                  Exercise Price be less than $.01 per share.

                  (b) Stock Combinations. In case the Company shall combine all
of the outstanding Common Shares into a smaller number of shares, the Exercise
Price in effect immediately prior to such combination shall be proportionately
increased.

                  (c) Reorganizations. If any capital reorganization or
reclassification of the capital stock of the Company other than a combination or
merger or sale of assets transaction provided for herein (but including any
consolidation or merger of the Company with or sale of all or substantially all
of its assets to a Continuing Entity) shall be effected, then, as a condition of
such reorganization, reclassification, consolidation, merger or sale, lawful and
adequate provision shall be made whereby each Holder shall thereafter have the
right to receive upon exercise of this Warrant such shares of stock, securities
or assets as may be issued or payable with respect to or in exchange for a
number of outstanding Common Shares equal to the number of Common Shares
immediately theretofore issuable upon exercise of this Warrant had such
reclassification, consolidation, merger or sale not taken place; and in any such
case appropriate provisions shall be made with respect to the rights and
interests of each Holder to the end that the provisions hereof (including
without limitation provisions for adjustment of the Exercise Price and of the
number of shares issuable upon exercise of this Warrant) shall thereafter be
applicable, as nearly as may be, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise hereof. The Company shall not
effect any such consolidation, merger or sale, unless prior to or simultaneously
with the consummation thereof the successor Company (if other than the Company)
resulting from such consolidation or merger or the Company purchasing such
assets shall assume by a written instrument executed and mailed by registered
mail, postage prepaid, or delivered to each registered Holder at the last
address of such Holder appearing on the Certificate Register (defined in Section
16 hereof), the obligation of the Company to deliver to such Holder such shares
of stock, securities or assets as, in accordance with the foregoing provisions,
such Holder may be entitled to upon exercise of this Warrant. The provisions of
this paragraph (c) shall similarly apply to successive consolidations, mergers
or sale of assets.

                  (d) Notice of Adjustment. Upon each adjustment of the Exercise
Price, the Company shall give prompt written notice thereof addressed to each
registered Holder at the address of such Holder as shown on the Certificate
Register, which notice shall state the Exercise Price resulting from such
adjustment and the increase or decrease, if any, in the number of Warrant Shares
issuable upon exercise hereof, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

                  (e) Fractional Shares. No fractional shares or scrip
representing fractional Common Shares shall be issued upon the exercise hereof.
Upon exercise by any Holder, such Holder shall be entitled to receive the
aggregate full number of Common Shares in which all the Warrant Shares being
subscribed for by such Holder may exercise and in lieu of any fractional share
to which such Holder would otherwise be entitled, an amount equal to such
fractional share multiplied by the then fair market value (as hereafter defined)
of Common Shares shall be paid by the Company in cash to such holder.

                                       10
<PAGE>   11
                  (f) Validity of Shares. All Common Shares which may be issued
upon exercise of this Warrant will, upon issuance, be legally and validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
with respect to the issue thereof.

                  (g) Fair Market Value. For the purposes of this Section 6, if
the Company's Common Shares shall be regularly traded in any market, its "fair
market value" shall be based on (i) if the Common Shares are listed on a
national stock exchange, the closing price on the principal stock exchange where
the Common Shares are listed and traded, or if there is no trading on a given
day, the mean between the closing bid and asked prices on such day on said
exchange, or (ii) if the Common Shares are not so listed, the mean between the
closing bid and asked prices on the over-the-counter market as furnished by a
national quotation service or the principal broker making a market; and in each
case the daily values so obtained shall be averaged over a period of ten (10)
consecutive trading days immediately prior to the date of the determination and
the average so obtained shall be deemed to be the "fair market value" of the
Common Shares hereunder. If the Common Shares are not regularly traded in any
market, its "fair market value" may be currently determined by the Board of
Directors of the Company for the purpose of any transaction hereunder, and such
determination shall be final and binding upon the Holders if it is made in good
faith and with due care.

                  (h) No Impairment. The Company will not, by amendment of this
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company under this
Section 6, but will at all times in good faith assist in the carrying out of all
the provisions of this Section 6 and in the taking of all such action as may be
necessary or appropriate in order to protect the conversion rights of the
Holders against impairment.

                  (i) Notice of Capital Changes. If at any time:

                  [1]      The Company shall declare any dividend or
                           distribution (other than a cash dividend) payable to
                           the holders of its Common Shares;

                  [2]      The Company shall offer for subscription pro rata to
                           the holders of Common Shares any additional shares of
                           stock of any class or other rights;

                  [3]      There shall be any capital reorganization or
                           reclassification of the capital stock of the Company,
                           or consolidation or merger of the Company with, or
                           sale of all or substantially all of its assets to,
                           another Company or business organization;

                  [4]      There shall be any issuance of securities convertible
                           into, or rights or warrants to purchase, securities
                           of the Company; or

                                       11
<PAGE>   12
                  [5]      There shall be a voluntary or involuntary
                           dissolution, liquidation or winding up of the
                           Company.

                  Then, in any one or more of such cases, the Company shall give
                  the Holders written notice by registered mail, postage
                  prepaid, of the date on which a record shall be taken for such
                  dividend, distribution or subscription rights or for
                  determining shareholders entitled to vote upon such
                  reorganization, reclassification, consolidation, merger, sale,
                  dissolution, liquidation or winding up and of the date when
                  any such transaction shall take place, as the case may be.
                  Such notice shall also specify the date as of which the
                  Holders may exercise this Warrant such that the Warrant Shares
                  of record shall participate in such dividend, distribution or
                  subscription rights, or shall be entitled to exchange the
                  Warrant Shares for securities or other property deliverable
                  upon such reorganization, reclassification, consolidation,
                  merger, sale, dissolution, liquidation, or winding up, as the
                  case may be. Such written notice shall be given at least 30
                  days prior to the transaction in question and not less than 20
                  days prior to the record date in respect thereto.

                  The adjustment to the number of Common Shares issuable upon
                  the exercise hereof and the adjustments to the Exercise Price
                  described in this Section 6 shall be made each time any event
                  listed in this Section 6 occurs.

                  If the Company takes any action affecting its Common Shares
                  after the date hereof, that would be covered by this Section 6
                  but for the manner in which such action is taken or
                  structured, other than an action described in this Section 6,
                  which would in any way diminish the value of this Warrant or
                  the Warrant Shares, then there shall be an adjustment as to
                  the Common Shares purchasable therefor and the Exercise Price
                  payable thereunder in such manner as the Board of Directors of
                  the Company shall in good faith determine to be equitable
                  under the circumstances.

         7. Sale of Warrant or Warrant Shares. Neither this Warrant nor the
Warrant Shares have been registered under the Securities Act of 1933, as
amended, or under the securities laws of any state. Neither this Warrant nor the
Warrant Shares may be sold, transferred, pledged, or hypothecated, in the
absence of (i) an effective registration statement for this Warrant or the
Warrant Shares, as the case may be, under the Act and such registration or
qualification as may be necessary under the securities laws of any state, or
(ii) an opinion of counsel reasonably satisfactory to the Company that such
registration or qualification is not required. The Company shall cause a
Certificate or Certificates evidencing all or any part of the Warrant Shares
prior to any such registration or qualification of Warrant Shares to bear the
following legend:

         The securities represented by this certificate have not been registered
         under the Securities Act of 1933, as amended, or the securities laws of
         any state (the "Securities Laws"). These securities may not be offered,
         sold, transferred, pledged, or hypothecated in the absence of
         registration under applicable Securities Laws, or the availability of
         an exemption therefrom. This Certificate will not be transferred on the
         books of the

                                       12
<PAGE>   13
         Company or any transfer agent acting on behalf of the Company except
         upon the receipt of an opinion of counsel, satisfactory to the Company,
         that the proposed transfer is exempt from the registration requirements
         of all applicable Securities Laws, or the receipt of evidence,
         satisfactory to the Company, that the proposed transfer is the subject
         of an effective registration statement under all applicable Securities
         Laws.

         The shares represented by this certificate are subject to and may be
         transferred only in compliance with the terms of a certain Amended and
         Restated Shareholders Agreement dated November 25, 1998, as amended,
         made by and among certain holders of securities of the Company. Copies
         of that Agreement are available for inspection at the principal or
         registered office of the Company.

         8. Replacement of Warrant. At the request of the Holder and on
production of evidence reasonably satisfactory to the Company of the loss,
theft, destruction or mutilation of this Warrant, the Company at its expense
will issue in lieu thereof a new Warrant of like tenor.

         9. No Voting Rights. Except as otherwise provided herein or in the
Shareholders Agreement (referenced in Section 16 hereof) or the Voting Agreement
(referenced in Section 16 hereof) or the Amended Certificate, this Warrant shall
not be deemed to confer upon the Holder any right to vote or to consent to or
receive notice as a stockholder of the Company, as such, in respect of any
matters whatsoever, or any other rights or liabilities as a stockholder, prior
to the exercise hereof.

         10. Expenses. The Company will pay all expenses and charges payable in
connection with the preparation, issuance and delivery of this Warrant and all
substitute Warrants. The Holder shall pay all taxes (other than issuance taxes,
including documentary stamp taxes, transfer taxes and other governmental
charges, which shall be paid by the Company) in connection with such issuance
and delivery of the Warrants and the Subscribed Shares.

         11. Reservation of Shares. The Company will at all times reserve and
keep available, free from preemptive rights, out of the aggregate of its
authorized but unissued Common Stock or its authorized and issued Common Stock
held in its treasury, solely for the purpose of enabling it to satisfy any
obligation to issue shares of Common Stock upon exercise of this Warrant, for
the maximum number of shares of Common Stock which may then be deliverable upon
the exercise of this Warrant. The Company covenants that all shares of Common
Stock which may be issued upon exercise of this Warrant will, upon issue, be
fully paid, nonassessable, free of preemptive rights and free from all taxes,
liens, charges and security interests with respect to the issue thereof.

         12. Investment Covenant. The Holder by its acceptance of this Warrant
covenants that this Warrant is, and the Warrant Shares issued hereunder will be,
acquired for investment purposes, and that the Holder will not distribute this
Warrant or the Warrant Shares in violation of any state or federal law or
regulations.

         13. Fractional Shares of the Holder. No fractional shares of Common
Stock will be issued in connection with any purchase hereunder but in lieu of
such fractional shares, the Company shall make a cash refund therefore equal in
amount to the product of the applicable fraction multiplied by the Exercise
Price then in effect.

                                       13
<PAGE>   14
         14. Computations. The certificate of any firm of independent public
accountants of nationally recognized standing selected by the Company shall be
conclusive evidence of the correctness of any computation under this Warrant.

         15. Investor Exit; Other Shareholder Rights. The Holder's rights with
respect to voting rights, the transfer of this Warrant and the registration and
sale of the Common Stock issuable hereunder are also governed by a certain (i)
Amended and Restated Registration Rights Agreement dated November 25, 1998,
between the Company and the holders of the Company's common and preferred
securities identified as "Investors" in such agreement, and (ii) Amended and
Restated Shareholders Agreement dated November 25, 1998, among the Company, and
the holders of the Company's common and preferred securities identified as
"Investors" in such agreement among the "Shareholders" and "Investors" as
identified therein, and (iii) Voting Agreement dated November 25, 1998, among
the Company, Broadband Solutions, LLC, Broadband Solutions II, LLC, and Vulcan
Ventures, Incorporated, the terms and conditions of which are incorporated
herein by reference. The Holder agrees that all Warrant Shares shall be subject
to these agreements.

         16. Owner of Warrant. The Company shall keep a register (the
"Certificate Register") of the Warrant Certificates and of their transfer and
exchange in accordance with the provisions of Sections 5 and 7 hereof. The
Certificate Register shall show the names and addresses of the respective
Holder(s) and the date and number of Warrants represented on the face of each
Warrant Certificate. The Company shall be entitled to treat the Person in whose
name a Warrant Certificate is registered as the absolute owner of such Warrant
Certificate for all purposes. The Company shall have no duty to inquire into
adverse claims to, or the authenticity of any signature of any purported holder
of, this Warrant.

         17. Miscellaneous.

                  (a) This Warrant shall be governed by and construed in
accordance with the laws of the State of Delaware, without reference to the
conflict of law principles thereof.

                  (b) This Warrant shall bind the Company, its successors and
assigns (including any Successor Company), and shall benefit and bind the
Holder, the Holder's successors and permitted assigns.

                  (c) The Section headings in this Warrant have been included
solely for ease of reference and shall not be considered in the interpretation
or construction of this Warrant. All references in this Warrant to "Sections"
shall be construed as references to numbered Sections of this Warrant.

                  (d) Any notice or delivery required or permitted by this
Warrant shall be deemed given or made for all purposes of this Warrant when (1)
the notice is in writing, and (2) the notice or the delivery is delivered by
hand or is mailed by registered mail, return receipt requested, addressed to the
intended recipient at (A) in the Company's case, the Company's Office, or (B) in
the Holder's case, the Holder's address as set forth in the Company's records or
at such other address as the Holder may designate by written notice to the
Company.

         (a) This Warrant entitles the Holder to earn, from time-to-time and

than the Effective Date, and purchase during the Exercise Period, for Subscribed
Shares in any amount equal to the number of Homes Passed (in excess of 750,000
plus those Homes Passed counted for purposes of earning Class A Warrants
pursuant to Section 6.1.1 of the Systems Access Agreement) in Cable Systems
which the Operator has designated as additional Committed Systems (on a one (1)
Warrant Share per each Home Passed basis), in accordance with Section 2.2 of the
Network Services Agreement; provided that:

                           (1) the number of Subscribed Shares issuable under
         this Warrant, to the extent of the number of Homes Passed in an
         additional Committed System designated under Section 2.2 of the Network
         Agreement (on a one (1) Warrant Share per Home Passed basis), will be
         cancelled and deemed forfeited by Holder (or its permitted transferee)

<PAGE>   5
         extent Holder or such Operator replaces the Homes Passed in such
         withdrawn Committed System with Homes Passed in another Committed
         System(s)or additional Committed Systems, provided, that Subscribed
         Shares issuable under this Warrant will not be cancelled or deemed
         forfeited if Operator terminates any of HSAC's exclusive rights to
         provision HSAC Services in any Committed Systems as provided for or
         permitted under the Systems Access Agreement or the Network Services
         Agreement; and provided further, that as of July 31, 2003, the parties
         shall effect a reconciliation of the total number of Homes Passed in
         all Committed Systems (in excess of 750,000) under the Network
         Agreement, the number of outstanding Class A Warrants and Class B
         Warrants, and the number of shares theretofore issued upon exercise of
         this Warrant and the Class A Warrant. If such reconciliation reveals
         that the total number of Homes Passed in all Committed Systems (in
         excess of 750,000) under the Network Agreement (after adding back in
         Homes Passed in Committed Systems and additional Committed Systems
         withdrawn from the Network Agreement pursuant to Sections 18.1, 18.2,
         18.3 and/or 18.6 thereof) is different than the total number of all
         outstanding Class A Warrants and Class B Warrants and Warrant Shares,
         then the number of Class A Warrants and/or Class B Warrants will be
         adjusted upward or downward, as the case may be. If the number of
         unexercised Class A Warrants and/or Class B Warrants then held by
         Vulcan is insufficient to cover any shortfall, then Vulcan (or its
         permitted transferee) shall return to HSAC a number of Warrant Shares
         necessary to meet such shortfall, and HSAC shall refund to Vulcan the
         exercise price paid by Vulcan for such returned Warrant Shares;

                           (2) the inspection and commissioning procedures set
         forth in Section 2.3 of the Network Agreement have been satisfied, and

                           (3) at no time may the number of such Subscribed
         Shares/Warrant Shares exceed, in the aggregate, the Maximum Number of
         Warrant Shares.

                  (b) To exercise this Warrant an authorized officer of Holder
(or its permitted transferee) shall, during the Exercise Period, on the day the
Holder wishes to exercise this Warrant (the "Exercise Date"):

                           (1) Complete and certify the Subscription Form by
         designating the number of Subscribed Shares to which the Holder (or
         such permitted transferee) is entitled to exercise and wishes to
         exercise pursuant to such Subscription Form and Section 1 hereof (which
         may be less than or equal to the Maximum Number of Warrant Shares);

                           (2) Surrender this Warrant to the Secretary at the
         Company's Office, and

                           (3) Upon the surrender of this Warrant to the
         Secretary, deliver to the Secretary at the Company's Office a certified
         or cashier's check payable to the Company's order in an amount equal to
         (i) the number of Subscribed Shares, times (ii) the Exercise Price.

                                       5
<PAGE>   6
In the event the Company has completed a Qualified Public Offering, the Holder
may at its option, in lieu of tendering a certified or cashier's check as
provided in subparagraph (3) above, exercise this Warrant by submitting, during
normal business hours, a duly executed exercise notice marked to reflect "Net
Issue Exercise," and specifying the number of shares of Warrant Shares to be
exercised. Upon a Net Issue Exercise, Holder shall be entitled to receive
Warrant Shares equal to the value of this Warrant (or the portion thereof being
exercised by Net Issue Exercise) by surrender of this Warrant to the Company
together with notice of such election, in which event the Company shall issue to
Holder a number of shares of the Company's Common Stock computed as of the date
of surrender of this Warrant to the Company using the following formula:

                           X = Y x (A-B)
                               _________
                                    A

         Where    X = the number of Warrant Shares to be issued to Holder;

                  Y = the number of Warrant Shares purchasable under this
                      Warrant (at the date of such calculation).

                  A = the Current Market Price of one share of the Company's
                      Common Stock (at the date of such calculation);

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

As used above, "Current Market Price" means, if the Company's Common Stock is
traded on a national securities exchange, the NASDAQ National Market System or
the over-the-counter market, the average of the last reported price over the
five (5) trading days immediately preceding the date of valuation at which the
Common Stock has traded on such national securities exchange, the NASDAQ
National Market System or the average of the bid and asked prices on the
over-the-counter market on the date of valuation.

                  (c) Notwithstanding any delay in the actual issuance of a
Stock Certificate or Receipt pursuant to Section 4 hereof, the Warrant Shares
shall be deemed issued for all purposes as of the opening of business on the
Exercise Date subject to the provisions of Section 6.1.3 of the Systems Access
Agreement, and the Holder shall for all purposes be deemed to be the holder of
record of the Subscribed Shares to which the Receipt or the Stock Certificate
pertains.

         4. Issuance of Certificate for Subscribed Shares. Upon the Holder's
exercise of this Warrant in accordance with Section 3, the Company shall deliver
to the Holder:

                  (a) If the Subscribed Shares constitutes the Maximum Number of
Warrant Shares (and as the Company chooses), either (1) a Stock Certificate, or
(2) a Receipt.

                                       6
<PAGE>   7
                  (b) If the Subscribed Shares constitute less than the Maximum
Number of Warrant Shares (and as the Company chooses), either

                           (1) (i) a Stock Certificate, together with (ii) a new
         Securities Purchase Warrant, containing the same terms and conditions
         as this Warrant, evidencing the Holder's continued right to subscribe
         (during the Exercise Period) for the remainder of the Maximum Number of
         Warrant Shares; or

                           (2) (i) a Receipt, together with (ii) a new
         Securities Purchase Warrant, containing the same terms and conditions
         as this Warrant, evidencing the Holder's continued right to subscribe
         (during the Exercise Period) for the remainder of the Maximum Number of
         Warrant Shares.

         5. Transfer of Warrant.

                  (a) This Warrant shall be registered on the books of the
Company, which shall be kept at its Office for that purpose, and shall be
transferable in whole or in part but only on such books, by the Holder (or
Holder's duly authorized representative) in person or by duly authorized
attorney substantially in the form of Exhibit B hereof, and only in compliance
with paragraph (b) below. The Company may issue appropriate stop orders to its
Secretary or transfer agent to prevent a transfer in violation of this Section 5
and Section 7.

                  (b) The Holder may transfer this Warrant to any Person or
Persons at any time during the Warrant Period by completing and signing the
transfer form (the "Transfer Form") in the form of transfer form attached as
Exhibit B to this Warrant; provided, however, that without the prior written
consent of the Company, this Warrant and all rights hereunder may be transferred
only (i) to an Affiliate, or (ii) in accordance with the requirements of Section
8 hereof and pursuant to the registration of this Warrant or the Warrant Shares
under the Securities Laws (except as otherwise limited by any applicable
shareholders buy-sell, registration rights, or voting agreements binding upon
the Holder) or subsequent to eighteen (18) months from the Effective Date hereof
an exemption under Rule 144 or other exemption from such registration. If at
least fifteen (15) working days before the end of the Exercise Period the Holder
completes and signs the Transfer Form and surrenders this Warrant to the
Secretary at the Company's Office, the Company shall, within ten (10) working
days after this Warrant's surrender, issue to the transferee or transferees
identified on the completed Transfer Form one or more new Securities Purchase
Warrants (containing the same terms and conditions as this Warrant) evidencing
the transferee's or transferees' right or rights to subscribe (during the
Exercise Period) for all or part of the Warrant Shares.

         6. Anti-Dilution. The maximum number of Warrant Shares and the Exercise
Price for any Subscribed Shares shall be adjusted if during the Exercise Period,
but before the Holder's exercise of this Warrant:

                                       7
<PAGE>   8
         (a) Issues of Shares. The Company shall issue any of its Common Shares
for a consideration per share which is less than the Exercise Price in effect
immediately prior to such issuance (other than shares issued to employees,
officers, directors or consultants of the Company pursuant to option plans
approved by the Board of Directors of the Company), the Exercise Price shall be
reduced to such lower price. For purposes of this subparagraph [a], the
following clauses shall also be applicable:

                           [1] Convertible Securities, Options and Rights. If,
         at any time the Company shall issue or sell any rights, options,
         warrants or other securities entitling the holders thereof to purchase
         Common Shares or convert such securities into Common Shares at a price
         per share (determined by dividing (i) the total amount, if any,
         received or receivable by the Company in consideration of the issuance
         or sale of such rights, options, warrants or other securities plus the
         total amount if any, payable to the Company upon exercise or conversion
         thereof (the "Total Consideration") by (ii) the number of additional
         Common Shares issuable upon exercise or conversion of such securities)
         which is less than the Exercise Price in effect on the date of such
         issuance or sale, the Exercise Price price shall be adjusted as of the
         date of such issuance or sale so that the same shall equal the price
         determined by dividing (i) the sum of (A) the number of Common Shares
         outstanding on the date of such issuance or sale multiplied by the
         Exercise Price in effect immediately prior thereto plus (B) the Total
         Consideration by (ii) the number of Common Shares outstanding on the
         date of such issuance or sale plus the maximum number of additional
         Common Shares issuable upon exercise or conversion of such securities.
         Simultaneously with all adjustments to the number and/or kind of
         securities, property and cash to be issued in connection with any such
         issuance, sale or conversion, the Exercise Price will also be
         appropriately adjusted so that at all times the holder hereof will not
         pay more than the aggregate purchase price to exercise this Warrant in
         full immediately after such adjustment as such holder had to pay
         immediately prior to such adjustment.

                           [2] Distributions, Share Dividends and Splits.

                                    (i) In case the Company declares a dividend
                  or other distribution payable in Common Shares or subdivides
                  its Common Shares into a greater number of Common Shares, the
                  Exercise Price in effect immediately prior to such declaration
                  or subdivision shall be proportionately decreased and the
                  number and kind of shares purchasable upon exercise of this
                  Warrant shall be adjusted so that the holders thereof shall be
                  entitled to receive the kind and number of shares or the other
                  securities of the Company (such other securities thereafter
                  enjoying the rights of shares) that the Holder would have
                  owned or have been entitled to receive after the happening of
                  any of the events described in this paragraph [2] had the
                  Warrant Shares been issued immediately prior to the happening
                  of such event or any record date with respect thereto.

                                    (ii) In case the Company shall distribute to
                  the holders of Common Shares (i) securities, (ii) property,
                  other than cash, or (iii) cash, without fair payment therefor,
                  then, and in each such case, the Holder upon exercise hereof
                  shall be entitled to receive such securities, property and
                  cash which such Holder would have received had

                                       8
<PAGE>   9
                  such Holder been the holder of record of the Common Shares,
                  subject, however, to such Holder agreeing to any conditions to
                  such distribution as were required of all other holders of
                  Common Shares in connection with such distribution.

                                    (iii) If the securities to be distributed by
                  the Company to persons other than holders of this Warrant
                  involve rights, warrants, options, or any other form of
                  convertible securities and the right to exercise or convert
                  such securities would expire in accordance with its terms
                  prior to the exercise of this Warrant, and without the
                  exchange of any such rights, warrants or options, then the
                  terms of such securities shall provide that such exercise or
                  convertibility shall remain in effect until thirty (30) days
                  after the date the holder of this Warrant becomes a holder of
                  Common Shares pursuant to the conversion thereof.

                           An adjustment made pursuant to this paragraph [2]
                  shall become effective immediately after the record date in
                  the case of a dividend or distribution and shall become
                  immediately effective after the effective date in the case of
                  a subdivision, combination or issuance. If, as a result of an
                  adjustment made pursuant to this paragraph B, the Holder after
                  exercise shall become entitled to receive shares of two or
                  more classes of capital or Common Shares and any other class
                  of capital stock of the Company, the Board of Directors of the
                  Company (whose determination shall be conclusive and shall be
                  described in a written notice to the Holder promptly after
                  such adjustment) shall determine the allocation of the
                  adjusted Exercise Price between or among shares of such
                  classes of capital stock or Common Shares and such other
                  classes of capital stock.

                           [3] Consideration. In case the Company shall issue
                  its Common Shares for a consideration wholly or partly other
                  than cash, the amount of the consideration other than cash
                  received by the Company shall be deemed to be the lesser of
                  (i) the fair market value on the issue date of the Common
                  Shares so issued by the Company, as determined in good faith
                  by the Board of Directors of the Company, less any cash
                  consideration, or (ii) the fair market value of such
                  consideration as determined in good faith by the Board of
                  Directors of the Company.

                           [4] Record Dates. In case the Company shall take a
                  record of the holders of its Common Shares for the purpose of
                  determining Holders entitled (i) to receive a dividend or
                  other distribution payable in Common Shares, or (ii) to
                  subscribe for or purchase Common Shares, then such record date
                  shall be deemed to be the date of the issue or sale of the
                  Common Shares issued upon the declaration of such dividend or
                  the making of such distribution or deemed to have been issued
                  upon the granting of such right of subscription or purchase,
                  as the case may be.

                           [5] Treasury Shares. The number of Common Shares
                  outstanding at any given time shall not include shares owned
                  or held by or for the account of the Company

                                       9
<PAGE>   10
                  in its treasury, and the disposition of any such shares so
                  owned or held shall be considered an issue of Common Shares.

                           [6] Minimum Exercise Price. In no case shall the
                  Exercise Price be less than $.01 per share.

                  (b) Stock Combinations. In case the Company shall combine all
of the outstanding Common Shares into a smaller number of shares, the Exercise
Price in effect immediately prior to such combination shall be proportionately
increased.

                  (c) Reorganizations. If any capital reorganization or
reclassification of the capital stock of the Company other than a combination or
merger or sale of assets transaction provided for herein (but including any
consolidation or merger of the Company with or sale of all or substantially all
of its assets to a Continuing Entity) shall be effected, then, as a condition of
such reorganization, reclassification, consolidation, merger or sale, lawful and
adequate provision shall be made whereby each Holder shall thereafter have the
right to receive upon exercise of this Warrant such shares of stock, securities
or assets as may be issued or payable with respect to or in exchange for a
number of outstanding Common Shares equal to the number of Common Shares
immediately theretofore issuable upon exercise of this Warrant had such
reclassification, consolidation, merger or sale not taken place; and in any such
case appropriate provisions shall be made with respect to the rights and
interests of each Holder to the end that the provisions hereof (including
without limitation provisions for adjustment of the Exercise Price and of the
number of shares issuable upon exercise of this Warrant) shall thereafter be
applicable, as nearly as may be, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise hereof. The Company shall not
effect any such consolidation, merger or sale, unless prior to or simultaneously
with the consummation thereof the successor Company (if other than the Company)
resulting from such consolidation or merger or the Company purchasing such
assets shall assume by a written instrument executed and mailed by registered
mail, postage prepaid, or delivered to each registered Holder at the last
address of such Holder appearing on the Certificate Register (defined in Section
16 hereof), the obligation of the Company to deliver to such Holder such shares
of stock, securities or assets as, in accordance with the foregoing provisions,
such Holder may be entitled to upon exercise of this Warrant. The provisions of
this paragraph (c) shall similarly apply to successive consolidations, mergers
or sale of assets.

                  (d) Notice of Adjustment. Upon each adjustment of the Exercise
Price, the Company shall give prompt written notice thereof addressed to each
registered Holder at the address of such Holder as shown on the Certificate
Register, which notice shall state the Exercise Price resulting from such
adjustment and the increase or decrease, if any, in the number of Warrant Shares
issuable upon exercise hereof, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

                  (e) Fractional Shares. No fractional shares or scrip
representing fractional Common Shares shall be issued upon the exercise hereof.
Upon exercise by any Holder, such Holder shall be entitled to receive the
aggregate full number of Common Shares in which all the Warrant Shares being

                                       10
<PAGE>   11
subscribed for by such Holder may exercise and in lieu of any fractional share
to which such Holder would otherwise be entitled, an amount equal to such
fractional share multiplied by the then fair market value (as hereafter defined)
of Common Shares shall be paid by the Company in cash to such holder.

                  (f) Validity of Shares. All Common Shares which may be issued
upon exercise of this Warrant will, upon issuance, be legally and validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
with respect to the issue thereof.

                  (g) Fair Market Value. For the purposes of this Section 6, if
the Company's Common Shares shall be regularly traded in any market, its "fair
market value" shall be based on (i) if the Common Shares are listed on a
national stock exchange, the closing price on the principal stock exchange where
the Common Shares are listed and traded, or if there is no trading on a given
day, the mean between the closing bid and asked prices on such day on said
exchange, or (ii) if the Common Shares are not so listed, the mean between the
closing bid and asked prices on the over-the-counter market as furnished by a
national quotation service or the principal broker making a market; and in each
case the daily values so obtained shall be averaged over a period of ten (10)
consecutive trading days immediately prior to the date of the determination and
the average so obtained shall be deemed to be the "fair market value" of the
Common Shares hereunder. If the Common Shares are not regularly traded in any
market, its "fair market value" may be currently determined by the Board of
Directors of the Company for the purpose of any transaction hereunder, and such
determination shall be final and binding upon the Holders if it is made in good
faith and with due care.

                  (h) No Impairment. The Company will not, by amendment of this
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company under this
Section 6, but will at all times in good faith assist in the carrying out of all
the provisions of this Section 6 and in the taking of all such action as may be
necessary or appropriate in order to protect the conversion rights of the
Holders against impairment.

                  (i) Notice of Capital Changes. If at any time:

                  [1]      The Company shall declare any dividend or
                           distribution (other than a cash dividend) payable to
                           the holders of its Common Shares;

                  [2]      The Company shall offer for subscription pro rata to
                           the holders of Common Shares any additional shares of
                           stock of any class or other rights;

                  [3]      There shall be any capital reorganization or
                           reclassification of the capital stock of the Company,
                           or consolidation or merger of the Company with, or
                           sale of all or substantially all of its assets to,
                           another Company or business organization;

                                       11
<PAGE>   12
                  [4]      There shall be any issuance of securities convertible
                           into, or rights or warrants to purchase, securities
                           of the Company; or

                  [5]      There shall be a voluntary or involuntary
                           dissolution, liquidation or winding up of the
                           Company.

                  Then, in any one or more of such cases, the Company shall give
                  the Holders written notice by registered mail, postage
                  prepaid, of the date on which a record shall be taken for such
                  dividend, distribution or subscription rights or for
                  determining shareholders entitled to vote upon such
                  reorganization, reclassification, consolidation, merger, sale,
                  dissolution, liquidation or winding up and of the date when
                  any such transaction shall take place, as the case may be.
                  Such notice shall also specify the date as of which the
                  Holders may exercise this Warrant such that the Warrant Shares
                  of record shall participate in such dividend, distribution or
                  subscription rights, or shall be entitled to exchange the
                  Warrant Shares for securities or other property deliverable
                  upon such reorganization, reclassification, consolidation,
                  merger, sale, dissolution, liquidation, or winding up, as the
                  case may be. Such written notice shall be given at least 30
                  days prior to the transaction in question and not less than 20
                  days prior to the record date in respect thereto.

                  The adjustment to the number of Common Shares issuable upon
                  the exercise hereof and the adjustments to the Exercise Price
                  described in this Section 6 shall be made each time any event
                  listed in this Section 6 occurs.

                  If the Company takes any action affecting its Common Shares
                  after the date hereof, that would be covered by this Section 6
                  but for the manner in which such action is taken or
                  structured, other than an action described in this Section 6,
                  which would in any way diminish the value of this Warrant or
                  the Warrant Shares, then there shall be an adjustment as to
                  the Common Shares purchasable therefor and the Exercise Price
                  payable thereunder in such manner as the Board of Directors of
                  the Company shall in good faith determine to be equitable
                  under the circumstances.

         7. Sale of Warrant or Warrant Shares. Neither this Warrant nor the
Warrant Shares have been registered under the Securities Act of 1933, as
amended, or under the securities laws of any state. Neither this Warrant nor the
Warrant Shares may be sold, transferred, pledged, or hypothecated, in the
absence of (i) an effective registration statement for this Warrant or the
Warrant Shares, as the case may be, under the Act and such registration or
qualification as may be necessary under the securities laws of any state, or
(ii) an opinion of counsel reasonably satisfactory to the Company that such
registration or qualification is not required. The Company shall cause a
Certificate or Certificates evidencing all or any part of the Warrant Shares
prior to any such registration or qualification of Warrant Shares to bear the
following legend:

                                       12
<PAGE>   13
         The securities represented by this certificate have not been registered
         under the Securities Act of 1933, as amended, or the securities laws of
         any state (the "Securities Laws"). These securities may not be offered,
         sold, transferred, pledged, or hypothecated in the absence of
         registration under applicable Securities Laws, or the availability of
         an exemption therefrom. This Certificate will not be transferred on the
         books of the Company or any transfer agent acting on behalf of the
         Company except upon the receipt of an opinion of counsel, satisfactory
         to the Company, that the proposed transfer is exempt from the
         registration requirements of all applicable Securities Laws, or the
         receipt of evidence, satisfactory to the Company, that the proposed
         transfer is the subject of an effective registration statement under
         all applicable Securities Laws.

         The shares represented by this certificate are subject to and may be
         transferred only in compliance with the terms of a certain Amended and
         Restated Shareholders Agreement dated November 25, 1998, as amended,
         made by and among certain holders of securities of the Company. Copies
         of that Agreement are available for inspection at the principal or
         registered office of the Company.

         8. Replacement of Warrant. At the request of the Holder and on
production of evidence reasonably satisfactory to the Company of the loss,
theft, destruction or mutilation of this Warrant, the Company at its expense
will issue in lieu thereof a new Warrant of like tenor.

         9. No Voting Rights. Except as otherwise provided herein or in the
Shareholders Agreement (referenced in Section 16 hereof) or the Voting Agreement
(referenced in Section 16 hereof) or the Amended Certificate, this Warrant shall
not be deemed to confer upon the Holder any right to vote or to consent to or
receive notice as a stockholder of the Company, as such, in respect of any
matters whatsoever, or any other rights or liabilities as a stockholder, prior
to the exercise hereof.

         10. Expenses. The Company will pay all expenses and charges payable in
connection with the preparation, issuance and delivery of this Warrant and all
substitute Warrants. The Holder shall pay all taxes (other than issuance taxes,
including documentary stamp taxes, transfer taxes and other governmental
charges, which shall be paid by the Company) in connection with such issuance
and delivery of the Warrants and the Subscribed Shares.

         11. Reservation of Shares. The Company will at all times reserve and
keep available, free from preemptive rights, out of the aggregate of its
authorized but unissued Common Stock or its authorized and issued Common Stock
held in its treasury, solely for the purpose of enabling it to satisfy any
obligation to issue shares of Common Stock upon exercise of this Warrant, for
the maximum number of shares of Common Stock which may then be deliverable upon
the exercise of this Warrant. The Company covenants that all shares of Common
Stock which may be issued upon exercise of this Warrant will, upon issue, be
fully paid, nonassessable, free of preemptive rights and free from all taxes,
liens, charges and security interests with respect to the issue thereof.

         12. Investment Covenant. The Holder by its acceptance of this Warrant
covenants that this Warrant is, and the Warrant Shares issued hereunder will be,
acquired for investment purposes, and that the Holder will not distribute this
Warrant or the Warrant Shares in violation of any state or federal law or
regulations.

                                       13
<PAGE>   14
         13. Fractional Shares of the Holder. No fractional shares of Common
Stock will be issued in connection with any purchase hereunder but in lieu of
such fractional shares, the Company shall make a cash refund therefore equal in
amount to the product of the applicable fraction multiplied by the Exercise
Price then in effect.

         14. Computations. The certificate of any firm of independent public
accountants of nationally recognized standing selected by the Company shall be
conclusive evidence of the correctness of any computation under this Warrant.

         15. Investor Exit; Other Shareholder Rights. The Holder's rights with
respect to voting rights, the transfer of this Warrant and the registration and
sale of the Common Stock issuable hereunder are also governed by a certain (i)
Amended and Restated Registration Rights Agreement dated November 25, 1998,
between the Company and the holders of the Company's common and preferred
securities identified as "Investors" in such agreement, and (ii) Amended and
Restated Shareholders Agreement dated November 25, 1998, among the Company, and
the holders of the Company's common and preferred securities identified as
"Investors" in such agreement among the "Shareholders" and "Investors" as
identified therein, and (iii) Voting Agreement dated November 25, 1998, among
the Company, Broadband Solutions, LLC, Broadband Solutions II, LLC, and Vulcan
Ventures, Incorporated, the terms and conditions of which are incorporated
herein by reference. The Holder agrees that all Warrant Shares shall be subject
to these agreements.

         16. Owner of Warrant. The Company shall keep a register (the
"Certificate Register") of the Warrant Certificates and of their transfer and
exchange in accordance with the provisions of Sections 5 and 7 hereof. The
Certificate Register shall show the names and addresses of the respective
Holder(s) and the date and number of Warrants represented on the face of each
Warrant Certificate. The Company shall be entitled to treat the Person in whose
name a Warrant Certificate is registered as the absolute owner of such Warrant
Certificate for all purposes. The Company shall have no duty to inquire into
adverse claims to, or the authenticity of any signature of any purported holder
of, this Warrant.

         17. Miscellaneous.

                  (a) This Warrant shall be governed by and construed in
accordance with the laws of the State of Delaware, without reference to the
conflict of law principles thereof.

                  (b) This Warrant shall bind the Company, its successors and
assigns (including any Successor Company), and shall benefit and bind the
Holder, the Holder's successors and permitted assigns.

                  (c) The Section headings in this Warrant have been included
solely for ease of reference and shall not be considered in the interpretation
or construction of this Warrant. All references in this Warrant to "Sections"
shall be construed as references to numbered Sections of this Warrant.

                                       14
<PAGE>   15
                  (d) Any notice or delivery required or permitted by this
Warrant shall be deemed given or made for all purposes of this Warrant when (1)
the notice is in writing, and (2) the notice or the delivery is delivered by
hand or is mailed by registered mail, return receipt requested, addressed to the
intended recipient at (A) in the Company's case, the Company's Office, or (B) in
the Holder's case, the Holder's address as set forth in the Company's records or
at such other address as the Holder may designate by written notice to the
Company.

         IN WITNESS WHEREOF, this Warrant has been executed as of the 25th day

Systems that are


                                     - 7 -
<PAGE>   8
Committed Systems as of the Effective Date or are designated as additional
Committed Systems pursuant to Section 2.2 of the Network Agreement at any time
after the Effective Date, exercisable one (1) Warrant Share per each Home Passed
that is in any such Committed System or additional Committed Systems on or
before July 31, 2001 ("Class A Warrant Date"), which Class A Warrant Date will
be subject to adjustment as set forth in Section 6.4 below.

                6.1.2 The Class B Warrant pursuant to which HSAC will issue to
Vulcan one Class B Warrant (up to a maximum of 2,500,000 Class B Warrants in the
aggregate) for up to 2,500,000 Homes Passed (beyond the Homes Passed counted for
purposes of earning Class A Warrants pursuant to Section 6.1.1 above) in Cable
Systems that are Committed Systems as of the Effective Date or are designated as
additional Committed Systems pursuant to Section 2.2 of the Network Agreement at
any time after the Effective Date, exercisable one (1) Warrant Share per each
such Home Passed that is in any such Committed System by July 31, 2003 ("Class B
Warrant Date"), which Class B Warrant Date will be subject to adjustment as set
forth in Section 6.4 below.

                6.1.3 All Class A Warrants and Class B Warrants shall be deemed
vested (i.e., eligible for exercise) immediately when the applicable Home Passed
is or becomes part of a Committed System or additional Committed System under
the Network Agreement, subject to (i) the provisions of Section 6.3 below, and
(ii) the inspection and commissioning procedures set forth in Section 2.3 of the
Network Agreement.

            6.2 Class A Warrants shall expire if unexercised on or before
December 31, 2011, and Class B Warrants shall expire if unexercised on or before
December 31, 2013, in each case subject to acceleration in accordance with the
terms of the Class A Warrant and Class B Warrant, as applicable.

            6.3 Class A Warrants and Class B Warrants, to the extent of the
number of Homes Passed in additional Committed System designated under Section
2.2 of this Agreement and Section 2.2 of the Network Agreement (on a one (1)
Warrant Share per Home Passed basis), will be cancelled and deemed forfeited by
Vulcan (or its permitted transferee) in the event Operators withdraw Committed
Systems under the Network Agreement for any reason other than pursuant to
Sections 18.1, 18.2, 18.3, and/or 18.6 of the Network Agreement, except to the
extent Vulcan or Operators replace the Homes Passed in such withdrawn Committed
System with Homes Passed in another Committed System(s) or additional Committed
Systems. Class A Warrants and Class B Warrants will not be cancelled or deemed
forfeited if Operator terminates any of HSAC's exclusive rights as provided for
or permitted under this Agreement or the Network Agreement. Effective as of the
Class B Warrant Date, the parties shall effect a reconciliation of the total
number of Homes Passed in all Committed Systems (in excess of 750,000) under the
Network Agreement, the number of outstanding Class A Warrants and Class B
Warrants, and the number of Warrant Shares theretofore issued upon exercise of
the Class A Warrants and Class B Warrants. If such reconciliation reveals that
the total number of Homes Passed in all Committed Systems (in excess of 750,000)
under the Network Agreement (after adding back Homes Passed in Committed Systems
and additional Committed Systems withdrawn from the Network Agreement pursuant
to Sections 18.1, 18.2, 18.3, and 18.6 of the Network Services Agreement) is
different than the total number of all outstanding Class A Warrants


                                     - 8 -
<PAGE>   9
and Class B Warrants and Warrant Shares, then the total number of Class A
Warrants and/or Class B Warrants will be adjusted upward or downward, as the
case may be. If the number of unexercised Class A Warrants and/or Class B
Warrants then held by Vulcan is insufficient to cover any shortfall, then Vulcan
(or its permitted transferee) shall return to HSAC the number of Warrant Shares
necessary to meet such shortfall, and HSAC shall refund to Vulcan the exercise
price paid by Vulcan for such returned Warrant Shares.

            6.4 In the event that the parties cannot agree on the Launch Date
for a Committed System for which Class A Warrants or Class B Warrants are
exercisable under Section 6.1.1 or 6.1.2 within the period specified in Section
2.4 of the Network Agreement, then the Class A Warrant Date and or Class B
Warrant Date (as applicable) for the Homes Passed in such Committed System shall
be extended by the time period beginning on the date on which the Launch Date
for such Committed System should have been designated pursuant to Section 2.2 of
the Network Agreement and the date on which HSAC actually commences revenue
billing for Data Subscribers in such Committed System.

            6.5 HSAC shall have the right to review and audit Operators' books
and records relating to the Committed Systems and Homes Passed as of July 31,
2001 and July 31, 2003 for purposes of confirming the number of Homes Passed for
which Class A Warrants and Class B Warrants are exercisable (and Warrant Shares
that have been issued upon exercise thereof) hereunder.

         7. OPTION TO WITHDRAW CABLE SYSTEMS. Operators shall have the right to
terminate the Network Agreement and/or withdraw Committed Systems from this
Agreement and the Network Agreement in accordance with the provisions of
Sections 18 and 19 of the Network Agreement.

         8. CONTENT PROVISIONING.

            8.1 All of the rights, terms and conditions of this Agreement are
expressly conditioned upon the parties entering into the Content Agreement. The
obligations of the parties with respect to the Vulcan Content (as defined in the
Content Agreement) shall apply to all Data Subscribers in the Committed Systems
and to every other HSAC data and/or Internet customer located in any geographic
region or market, regardless of whether such customer is a customer of an
Operator or of an MSO or Cable System operated by an unrelated party, subject to
and in accordance with the terms of the Content Agreement.

            8.2 Until such time as Operators develop Content for a Startup Page
and a Web Site, HSAC shall create a temporary Operator-branded Startup Page
("Temporary Startup Page") and Web Site ("Temporary Web Site") for each
Committed System and orchestrate local community Content. Such Temporary Startup
Page and Temporary Web Site shall comply with the branding and all other
requirements set forth in Section 7.6.5 in the Network Agreement). All "net"
revenues (i.e., gross advertising and other sales revenues less any ad agency
charges, or commissions) resulting from advertising revenues, E-commerce and any
other revenues generated by or from such Temporary Startup Page and Temporary
Web Site (including any fees for links) shall be divided evenly between HSAC and
the applicable Committed System's Operator.

             8.3 The Content on such Temporary Startup Page and Web Site shall
be replaced upon reasonable notice to HSAC from that Committed System's Operator
with Content designated by Vulcan and/or the applicable Committed System's
Operator for a Startup Page and Web Site. HSAC shall provide every Committed
System's Operator with an easy and inexpensive means to constantly update and
modify the Content for such Operator's Startup Page and Web Site. All revenues
resulting from advertising revenues, E-commerce and any other ancillary revenues
generated by or from any Vulcan- or Operator-controlled or designated Content,
Startup Page, or Web Site (including any fees for links) shall be paid to or
retained by Vulcan or the applicable Committed System's Operator, and no portion
of such revenues shall be paid to, retained by or shared with HSAC. Conversely,
all revenues generated from HSAC's Web Site (as defined in the Content
Agreement) resulting from advertising revenues, E-commerce, other HSAC Content
(as defined in the Content Agreement), and any other revenues (including any
fees for links) generated from such HSAC's Web Site, shall be paid to or
retained by HSAC and no portion of such revenues shall be paid to, retained by
or shared with any Vulcan or any Operator.

         9.  [Intentionally Omitted]

         10. COMPETITIVE SERVICES.

            10.1 HSAC shall have the right to market and deploy data
connectivity services using analog modems that are commercially available as of
the Effective Date and do not operate at speeds greater than 128 KBPS to
"dial-up" residential and commercial customers in Committed System market areas
that do not qualify as Homes Passed and do not utilize the Operator's RF
Plant/head-end equipment and/or the HSAC Network Equipment. CONFIDENTIAL
MATERIAL REDACTED AND FILED SEPARATELY WITH THE COMMISSION. HSAC shall retain
such "dial up" customers in the event of any withdrawal of Committed Systems
from the Network Agreement or the termination of the Network Agreement by
Operator; provided, that if any Operator expands/upgrades its system such that
HSAC's "dial-up" customers eventually qualify as Homes Passed or Cable
Subscribers, HSAC shall make commercially reasonable efforts to enroll such
Cable Subscribers as Data Subscribers.

            10.2 Unless an Operator gives its prior written approval, HSAC
agrees that it shall not compete with Operators, deploy new dial-tone or xDSL
services, perform HSAC Services, or perform any Optional Services in any market
in which any of Operators or any affiliate owns, controls or operates a Cable
System (regardless of whether such Cable System is a Committed System) or
competes as CLEC. However, HSAC shall have the right without Operator's prior
written approval to develop and offer Internet Access and related services for
MSO's not affiliated with any of Operators in those market areas where no
Operator or any affiliate owns, controls and/or operates a Cable System or
competes as a CLEC. If such area eventually falls within or overlaps a market in
which an Operator or any affiliate owns, controls and/or operates a Cable
System, HSAC shall not be required to abandon or curtail its efforts with
respect to any its then existing deployments of connectivity services.

             10.3 Unless an Operator gives its prior written approval in regard
to a particular Committed System, HSAC shall not deploy new dial-tone or xDSL
services in the market areas of such Committed System; provided, that HSAC shall
not be required to abandon or curtail its efforts with respect to any existing
deployments of competing connectivity services which pre-date the Effective
Date, so long as HSAC has provided Operators with a detailed list of such
dial-tone or xDSL services before the Effective Date.

             10.4 HSAC shall not deploy Worldgate(R), WebTV(R), Optional
Services, or VBI (video blanking interval), digital TV products in the market
areas of any Committed Systems or other areas in which any Operator operates a
Cable System.

             10.5 HSAC's deployment of any Optional Service in the Committed
Systems or any products or services not specifically contemplated in this
Agreement in the Committed Systems is subject to agreement among or between the
parties on a case-by-case, system-by-system basis. The parties shall separately
negotiate the terms and conditions applicable to any such Optional Services on a
case-by-case basis.

             10.6 HSAC acknowledges and agrees that, with respect to any Cable
Systems that are not Committed Systems hereunder, there are and shall be no
restrictions or limitations on the ability of any Operator to compete with HSAC,
to engage any competitor(s) of HSAC to provide the HSAC Services (regardless of
the Method of Access) or to enter into any other business arrangements with
competitor(s) of HSAC.

         11. TERM. The term ("Term") of this Agreement shall commence effective
as of the Effective Date and shall continue until midnight of the day HSAC
ceases to provide HSAC Services to Data Subscribers in any geographic area or
region.

caused by "Year 2000 problems."

             12.2 Each of Vulcan, Charter, and Marcus hereby represents and
warrants, severally, but not jointly, and only as to itself, to HSAC as follows:

             13.2 Each of Charter and Marcus (severally and not jointly, and
only as to itself) will indemnify, defend, and hold harmless HSAC and its
affiliates, agents, successors, assigns, representatives, officers, and
directors from and against any liabilities, lawsuits, penalties, claims,
demands, awards, judgments, settlements, costs, and expenses (including, without
limitation, reasonable attorneys' fees and expenses on account thereof) that
arise or result from: (i) the breach by the indemnifying party of any of its
representations, warranties or covenants hereunder, or (ii) the indemnifying

         14. LIMITATION OF LIABILITY; INSURANCE.

             14.1 EXCEPT FOR THE INDEMNIFICATION OBLIGATIONS DETAILED IN SECTION
13 ABOVE, IN NO EVENT WILL EITHER PARTY HERETO BE LIABLE TO THE OTHER PARTY FOR
ANY INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES (EVEN IF THAT PARTY HAD BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES), ARISING FROM OR RELATED TO A BREACH
OF THIS AGREEMENT, INCLUDING WITHOUT LIMITATION LOSS OF REVENUE OR ANTICIPATED
PROFITS OR LOST BUSINESS.

             14.2 At all times during the Term, HSAC shall maintain (i)
appropriate policies of general liability, casualty, and business interruption

employees against injury to themselves or others and casualty accidents while

             14.3 Each of HSAC and Operators acknowledges that the rights
granted, and services to be provided to each other hereunder are of a special,
unique, unusual, extraordinary, and intellectual character, giving them peculiar
value, the loss of which cannot be reasonably or adequately compensated in

hereunder would cause the other party irreparable injury and damage. Subject to
Section 9.2.2 off the Content Agreement, each party agrees that, if it commits
or is about to commit a material breach of this Agreement, the other party will
be entitled to injunctive or other equitable relief as a remedy for any such
actual or threatened material breach, without the requirement to post any bond
or other security therefor.

             15.2 CLOSING. The closing of this Agreement and the transactions

         15.4 ASSIGNMENT. Except as set forth below, HSAC shall not have the
right to assign this Agreement to any person or entity without the prior written
consent of Operators, except it may without Operator's consent assign its
rights, but not its obligations, to a subsidiary of HSAC, provided that no such
assignment will relieve HSAC of liability for its obligations hereunder. Any
Operator may assign this Agreement to any person or entity, and this Agreement
shall be binding and inure to the benefit of such Operator's successors and
assigns. Vulcan may assign its rights in the Class A Warrants and Class B


                                     - 16 -
<PAGE>   17
Warrants only to the extent permitted in the Class A Warrant or Class B Warrant
(as applicable). Each party shall be permitted to assign this Agreement and
grant a security interest in its contract rights and tangible/intangible
property interests (including the HSAC Network Equipment and Home Equipment
Packages owned by such party) arising under this Agreement, the Network
Agreements and Other Agreements for purposes of securing financing from its
commercial lender(s). However, as a condition to doing so, HSAC shall be
obligated to obtain non-disturbance agreements in form and substance
satisfactory to Operators from each such lender under which such lender agrees
that, notwithstanding such lender's exercise of its rights as a secured
creditor, such lender and its assigns shall not disturb, affect, or interfere
with HSAC's provision of the HSAC Services hereunder. All assignments in
contravention of this Section 15.4 shall be null and void and of no force or
effect. Either party shall provide the other party with thirty (30) days prior
written notice of any permitted assignment hereunder.

             15.5 AMENDMENT AND WAIVER. Any term of this Agreement may be
amended and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of all of the parties unless
otherwise expressly permitted in this Agreement, and any written waiver by any
party of any breach of any term or condition shall not be deemed to be a waiver
of any subsequent or other breach, term or condition of this Agreement.

             15.6 CONFIDENTIAL INFORMATION.

                  15.6.1 Each party agrees that it shall not, during or for a
period of five (5) years after the Term of this Agreement, permit the
duplication, use, or disclosure of any Confidential Information to any person
(other than an employee, agent, or representative of the other party who must
have such information for the performance of its obligation hereunder), unless
such duplication, use or disclosure is specifically authorized by the other
party in writing. Each party shall (i) not disclose any Confidential Information
to any third person without the express written consent of the other party; (ii)
not use, directly, indirectly, or in concert with any other person, any
Confidential Information for any purpose other than the performance of their
obligations under this Agreement; (iii) use reasonable diligence, and in no
event less than that degree of care which such party uses in respect to its own
Confidential Information of like nature, to prevent the unauthorized disclosure
or reproduction of such information. Without limiting the generality of the
foregoing, to the extent that this Agreement permits the copying of Confidential
Information, all such copies shall bear the same confidentiality notices,
legends, and intellectual property rights designations that appear in the
original versions.

                  15.6.2 The confidentiality obligations set forth in Section
15.6.1 shall not be applicable to Confidential Information which is in the
public domain; information known to the recipient party as of the date of this
Agreement as indicated by the recipient's written records, unless the recipient
party agreed to keep such information in confidence at the time of its receipt;
information properly obtained hereafter from a source who is not under an
obligation of confidentiality with respect to such information; information that
is independently developed by the receiving party through persons who have not
had, either directly or indirectly, access or knowledge of such Confidential
Information which can be verified by independent evidence; or information that
that the


                                     - 17 -
<PAGE>   18
receiving party is obligated to be produced by law, provided that any party that
is so ordered to produce Confidential Information shall give notice thereof to
the other party and cooperate reasonably with any attempt by the notified party
to enjoin its disclosure.

                   15.6.3 Apart from HSAC's obligations to Operators under this
Section 15 concerning confidentiality, HSAC shall have no obligation to delete
or destroy Operator's information, including Operator's Customer Lists or other
Data Subscriber listings, from its computer systems or backup and archival
libraries until such time as HSAC's regular procedures for elimination of such
data would normally delete or destroy such information. Following a Data

2. HSAC Services and Vulcan Content.

         2.1 Exclusive Provision of Vulcan Content. Vulcan Content will be
exclusive within the HSAC Services as follows:

                  2.1.1 Must Carry. HSAC must carry, on an exclusive basis, as
part of the HSAC Services for any and all Cable Systems and Subscribers for
which HSAC provides the HSAC Services and/or any other Internet access or
related services, regardless of whether any such Cable System is or any such
Subscribers reside within a Vulcan System or an Independent System, and
regardless of Subscriber's Method of Access, all Vulcan Content, and any and all
other Content that Vulcan designates as part of the Vulcan Content. From time to
time during the term of this Agreement, Vulcan may designate Content for
inclusion in the Vulcan Content, or may modify the Vulcan Content, by notifying
HSAC in writing of the Content to be included. HSAC will add such Content to the
HSAC Services and/or any other Internet access or related services within ten
(10) days of its designation by Vulcan as part of the Vulcan Content. HSAC will
not be in breach of the foregoing obligation if HSAC does not receive any
specialized equipment required to carry the Vulcan Content, which equipment is
otherwise not required in order to perform the HSAC Services, on a timely basis
following the submission of a complete order by HSAC to the vendor of such
equipment before the lead times required by such vendor in order to deliver such
equipment in sufficient time for HSAC to meet such ten (10)-day period.

                  2.1.2 No Competition. HSAC will not, with respect to any Cable
System, any other Method of Access, or for any Subscribers develop, provide,
license, or otherwise include any information, services, Web Pages or Web Sites,
audio, video, sound, Telephony, or other Content that competes, directly or
indirectly, with Vulcan Content ("COMPETING CONTENT"). The decision whether
Content competes with Vulcan Content will be in Vulcan's sole discretion. Vulcan
will request in writing the immediate removal of any Competing Content, which
request HSAC will honor within three (3) days. Failure to honor such a request
will constitute a material breach of this agreement.

                  2.1.3 HSAC Services. Vulcan acknowledges that HSAC has the
right under this Agreement to create and include HSAC Content and publish such
HSAC Content on a Web Site owned or controlled by HSAC ("HSAC's Web Site") in
accordance with the following provisions: (a) such Web Site shall be directly
accessible through no more than one browser user interface button ("BUI") to be
located on Vulcan's Startup Page (the size, placement, and other aspects of such
BUI shall be determined by Vulcan at its sole discretion), (b) such Web Site
will include on the start page thereof at least one BUI to a nationally
recognized Internet Search engine (e.g., Yahooo or Excite), (c) such Web Site
will include on the start page thereof at least one BUI to Vulcan's Startup
Page, (d) any HSAC Content on such Web Site will be limited to Local Content and
BUIs to other Web Pages, (e) any HSAC Content included on such Web Site will not
constitute Competing Content, (f) such Web Site will have a domain name that is
different from the Vulcan Startup Page and related Web Sites, and (g)
notwithstanding clause (d) above, HSAC shall have the right to sell advertising
and otherwise to derive and retain revenues from such HSAC Content.


                                      -5-
<PAGE>   6
         2.2 Form of Content. The Vulcan Content may include, in Vulcan's sole
discretion, any combination of the following:

                  2.2.1 Startup Page. Vulcan may, in its sole discretion,
design, or have designed a Startup Page, or multiple Startup Pages, for Cable
Systems and other Subscribers. Until such time as Vulcan's Startup Page is
available, HSAC may develop a Startup Page for any Cable System or Subscribers
subject to the branding provisions of Section 2.2.5; provided, that, such
Startup Page will be replaced by Vulcan's Startup Page when it is available. To
the extent technically feasible, HSAC will ensure that any Startup Page provided
by Vulcan is the first or default screen encountered by Subscribers when they
access HSAC Services, regardless of the Method of Access, and that such Startup
Page and Vulcan Content cannot be replaced or bypassed by Subscribers without
Vulcan's express written permission.

                  2.2.2 EPG. If HSAC's Website or HSAC Services includes an EPG,
then prior to inclusion of such EPG as part of such HSAC's Website or HSAC
Services, HSAC will present the proposed design, form, content, and aesthetics
of such EPG to Vulcan for Vulcan's approval, which approval may be withheld in
Vulcan's sole discretion. If Vulcan disapproves of the proposed EPG, HSAC will
redesign the EPG based on input from Vulcan, or Vulcan may, in its sole
discretion, provide to HSAC an EPG of its own design for inclusion as part of
the HSAC's Website or HSAC Services. In addition, Vulcan will have the right to
dictate to HSAC the priority to be afforded various listings, such as the Vulcan
Content, any television channels, and other services, within any EPG included on
HSAC's Web Site or in HSAC Service.

                  2.2.3 [Intentionally Deleted]

                  2.2.4 Other Points of Subscriber Access. To the extent that
Subscribers are able or become able to access HSAC Services without relying on
any of the methods described in Section 2.2.1 above ("NEW ACCESS METHOD"), HSAC
will immediately notify Vulcan of the New Access Method, and HSAC and Vulcan
will cooperate in good faith to ensure that the New Access Method provides
exclusively for the delivery of Vulcan Content.

                  2.2.5 Branding. The Vulcan Startup Page (and any temporary
Startup Page developed by HSAC under Section 2.2.1 above) will be marketed,
deployed, and supported only under brands, service marks, and trademarks
designated by Vulcan or its affiliates. Vulcan will be responsible for
registering such brands, service marks, and trademarks and obtaining a matching
or closely related Internet domain name. Such trademarks and domain names will
be owned by Vulcan or an affiliate. If such domain names are temporarily owned
or controlled by HSAC, HSAC will take all steps necessary promptly to transfer
and assign such domain names to Vulcan or its designated affiliate. Vulcan will
include the brand, service mark or trademark of any Independent System utilizing
the HSAC Services on the Vulcan Startup Page for such Independent System (the
size, placement, and other aspects of such brand, service mark or trademark
shall be determined by Vulcan, in its sole discretion, provided, that such
brand, service mark or trademark shall be reasonably visible to Subscribers ).


                                      -6-
<PAGE>   7
                  2.2.6 Property Rights Notices. HSAC will include in the Vulcan
Content such proprietary rights notices, credits, World Wide Web hyperlinks, and
other such information as Vulcan directs, and will take no steps to alter,
remove, obscure, or otherwise interfere with any proprietary rights notices in
the Vulcan Content.

                  2.2.7 Delivery of Vulcan Content to HSAC. Vulcan shall be
responsible for the delivery of all Vulcan Content to HSAC for inclusion in HSAC
Services. Vulcan Content shall be delivered to HSAC in electronic form suitable
for inclusion in the HSAC Services, either to a central HSAC server or to
equipment located in the headend of each Cable System, as designated by HSAC.
HSAC and Vulcan shall reasonably cooperate to determine the most suitable format
for the electronic delivery of the Vulcan Content.

         2.3 Pre-Existing Systems. Notwithstanding anything in Section 2.1 to
the contrary, HSAC may itself provide or have provided by a third party Content
other than Vulcan Content to those Cable Systems listed in Schedule 2.3 (each a
"GRANDFATHERED SYSTEM"). HSAC will use its best efforts to convert each
Grandfathered System to exclusive use of Vulcan Content upon the expiration or
termination of the agreements between HSAC and Grandfathered Systems, or at such
earlier dates as those agreements otherwise permit.

         2.4 HSAC as ISP. HSAC may, from time to time, enter into agreements
with Independent Systems whereby HSAC will serve as an ISP within each such
Independent System. HSAC will notify Vulcan in writing within ten (10) days of
entering into any agreement with an Independent System, and HSAC will
exclusively provide Vulcan Content, in accordance with Section 2.1 above, to
each such Independent System, as though that Independent System were a Cable
System subject to the terms of this Agreement.

                  2.4.1 Exception: Private Label ISP. Subject to HSAC's
obtaining Vulcan's prior written consent on a case-by-case basis, and Section
2.1 notwithstanding, HSAC may enter into a relationship or arrangements with an
Independent System pursuant to which HSAC provides ISP services that: (i) are
not required be delivered exclusively under the Vulcan Marks, and (ii) do not
include the requirement that the Independent System exclusively receive Vulcan
Content. The terms and conditions of any such relationship or arrangements shall
be subject to Vulcan's prior written approval.

                  2.4.2 Tailored Content. Within ten (10) days of entering into
an ISP or similar agreement with an Independent System, HSAC will notify Vulcan
in writing of such agreement and provide sufficient information concerning the
Independent System for Vulcan to be able to tailor the Vulcan Content to the
market served by the Independent System. If HSAC has not received Vulcan Content
tailored to the Independent System within thirty (30) days of delivery of notice
of the agreement, then HSAC will use Vulcan Content already in use for Cable
Systems, until such time as Vulcan provides tailored Content to HSAC for the
Independent System.

         2.5 [Intentionally Deleted]

         2.6 Other HSAC Activities. Nothing in this Agreement shall be construed
to restrict HSAC's right to provide Web Site design, management, and hosting
services, as

long as such services and activities are not reasonably deemed by Vulcan to be
competitive with Vulcan Content.

         2.7 Pricing. The Vulcan Content will be provided to Cable Systems
accessing the Vulcan Content through the HSAC Services free of charge until ten
years from the Effective Date. At such time, Vulcan may charge HSAC, the Vulcan
Systems, and the Independent Systems for the provision of the Vulcan Content,
provided that any fee that Vulcan may charge HSAC for the provision of the
Vulcan Content shall not be more than the lowest fee charged by Vulcan to
another similar ISP for substantially the same Vulcan Content. Nothing in this
Section 2.7 shall prevent Vulcan from deriving revenues from the Vulcan Content
from third parties, including, without limitation, by charging Subscribers for
access to particular Vulcan Content, from the sale of advertising on any Vulcan
Content, the provision of BUIs to Web Pages, and other transactions.

3. Development of Content.

         3.1 Development of Vulcan Content. Subject to the terms and conditions
of this Agreement and HSAC's technical requirements, Vulcan will, in its sole
discretion, develop, acquire, or license all Content that will make up the
Vulcan Content, will have final input on all business and technical decisions
concerning how best to deliver Vulcan Content to Cable Systems and to
Subscribers, and will be able to update the Vulcan Content from time to time in
its sole discretion.

         3.2 Cooperation. HSAC will, at its own cost and expense, provide
commercially reasonable assistance Vulcan in the development of Vulcan Content
by providing Vulcan any and all support required for Vulcan to develop Vulcan
Content that can be delivered using HSAC Network Equipment to Cable Systems and
from Cable Systems to Subscribers. Such assistance will include, without
limitation, the provision by HSAC of: (i) all technical information, materials,
and requirements of the HSAC Network Equipment; (ii) access to HSAC engineers
and technical personnel to the extent necessary to ensure accurate and reliable
delivery of Vulcan Content to Cable Systems and to Subscribers; and (iii) access
to test equipment, test suites, software, facilities, and simulations in order
for Vulcan to test the operation of the Vulcan Content on the HSAC Network
Equipment.

4. Marketing and Promotional Activities.

         4.1 HSAC Marketing. HSAC's responsibilities with respect to marketing
and promotion of the HSAC Services and the Vulcan Content will be as set forth
in the Network Services Agreement and the Access Agreement, with the further
obligation that HSAC conduct such marketing and promotion to Independent
Systems. Vulcan shall make available, on the same basis as Vulcan makes
available to other distributors of the Vulcan Content, existing training and
marketing materials for HSAC's marketing and MSO sales personnel to assist such
personnel in marketing the HSAC Service, including the Vulcan Content, to MSOs
and to end users.

         4.2 Vulcan Marketing. Vulcan will have the right but not the obligation
to market and promote the Vulcan Content and the HSAC Services to Subscribers
and to Cable Systems by any means that Vulcan deems effective.

5. Provision of HSAC Services and Deployment of Vulcan Content.

         5.1 By HSAC. HSAC will have the responsibility for providing HSAC
Services and HSAC Network Equipment to Cable Systems and Subscribers. HSAC will,
at its own cost and expense, install all HSAC Network Equipment necessary for
the delivery of Vulcan Content to Cable Systems and Subscribers. To the extent
that the accurate and reliable delivery of Vulcan Content to Subscribers
requires the purchase of equipment at any head-end that exceeds an aggregate
cost of three thousand dollars ($3,000) for such head-end during the term of
this Agreement, or the purchase of additional bandwidth to permit the delivery
and/or update of such Content, Vulcan shall reimburse HSAC for the cost of such
equipment and bandwidth. Except to the extent set forth in Section 11.4 of this
Agreement, Vulcan will have no responsibility for, or liability arising out of,
the use, maintenance, or operation of the HSAC Network Equipment.

         5.2 By Vulcan. Vulcan will have the responsibility for delivering
Vulcan Content to HSAC for inclusion in delivery of HSAC Services to Cable
Systems, in accordance with Section 2.2.7 of this Agreement. Vulcan may, in its
sole discretion, localize or tailor Vulcan Content to suit the markets of
particular Cable Systems and/or Subscribers. Vulcan and HSAC will determine
mutually agreeable times, methods, and media for delivery of the Vulcan Content,
as well as for future delivery of Content to be added to the Vulcan Content.

         5.3 Deployment of Vulcan Content. Subject to Section 2.2.7 of this
Agreement, HSAC shall operate and manage the HSAC Network Equipment in such a
manner to insure the reliable delivery of Vulcan Content to Subscribers at
sufficiently high rates of transmission. Vulcan may, in its sole discretion,
determine that the HSAC Network Equipment or certain installations of the HSAC
Network Equipment is or are not providing Subscribers with access to the Vulcan
Content with sufficient reliability or at sufficiently high rates of
transmission. In such event, HSAC will, at HSAC's expense (subject to Section
5.1 above), place Vulcan Equipment with the HSAC Network Equipment, and will
install, operate, and maintain such Vulcan Equipment.

under this Agreement.

         7.2 HSAC. HSAC owns and retains all right, title and interest in and to
the HSAC IP Rights, including without limitation: (i) the HSAC Services, (ii)
the HSAC Marks, and (iii) any Confidential Information and any hardware,

Agreement.

8. Confidential Information.

         8.1 Disclosure. HSAC and Vulcan acknowledge that either party
("DISCLOSING PARTY") may disclose to the other party ("RECIPIENT") certain
information related to the Disclosing Party's business in any form, including,
without limitation: (i) customer information, (ii) the terms and conditions of
this Agreement, (iii) all dates, summaries, reports or information of all kinds,
whether oral or written, acquired, devised or developed in any manner by or from
the Disclosing Party's files, and (iv) financial, statistical, personnel, or
technical information, software or documentation, which the Disclosing Party
deems proprietary or confidential ("CONFIDENTIAL INFORMATION"). In the event
that Recipient receives such Confidential Information, Recipient agrees to keep
such information confidential by using the same care and discretion that it uses
with its own information that it designates as confidential.

         8.2 Limitation on Use. The Recipient will not permit the duplication,
use, or disclosure of any Confidential Information to any person (other than an
employee, agent, or representative of the Recipient who must have such
information for performance of its obligation hereunder), unless such
duplication, use, or disclosure is specifically authorized by the Disclosing
Party in writing or required by law. The Recipient will: (i) not disclose any
Confidential Information to any third person without the prior written consent
of the Disclosing Party, (ii) not use, directly, indirectly, or in concert with
any other person, any Confidential Information for purposes other than
performance of obligations under this Agreement, and (iii) use reasonable
diligence, and in no event less than that degree of care that the Recipient uses
with respect to its own Confidential Information of like nature, to prevent the
unauthorized disclosure or reproduction of such information. Without limiting
the generality of the foregoing, to the extent that this Agreement permits the
copying of Confidential Information, all copies must bear the same
confidentiality notices, legends, and intellectual property rights designations
that appear on the original versions.

         8.3 The above obligations of confidentiality will terminate five (5)
years after expiration of this Agreement, and will not impose an obligation on
Recipient with respect to any portion of the information received that:

                  8.3.1 is now generally known or available, or hereafter,
through no act or failure on the part of Recipient, becomes generally known or
available;


                                      -11-
<PAGE>   12
                  8.3.2 is known to Recipient prior to receiving such
information from an independent source not subject to confidentiality
restrictions;

                  8.3.3 is authorized for dissemination to others by Disclosing
Party without restriction on disclosure;

                  8.3.4 can be shown to be independently developed by Recipient;
or

                  8.3.5 Recipient is required by law, rule, regulation, court
order, or the like to disclose, provided, that, Recipient immediately notifies
the Disclosing Party of the required disclosure, cooperates if the Disclosing
Party elects to object to the required disclosure, and only produces that
information specifically required to be disclosed.

         8.4 The parties acknowledge that any threatened or actual unauthorized
use or disclosure of any Confidential Information will cause the Disclosing
Party great and irreparable harm, and that money damages will be insufficient to
compensate for such unauthorized use or disclosure. Without limiting any of its
other rights or remedies, the Disclosing Party will be entitled to receive
immediate injunctive or equitable relief to prevent or terminate any
unauthorized disclosure, without the requirement to post any bond or other
security therefor.

9. Term.

         9.1 Term. The term of this Agreement will commence as of the Effective
Date and will continue in full force and effect until terminated by as provided
in Section 9.2 below.

         9.2 Breach and Termination

                  9.2.1 If not earlier terminated pursuant to Section 9.2.3
below, this Agreement will automatically terminate upon the termination or
expiration of the Access Agreement.

                  9.2.2 In the event of any breach of this Agreement, the
non-breaching party shall, in addition to any other remedy provided hereunder,
or available at law or in equity, be entitled to bring an action at law for
money damages, or in equity for specific performance or to seek injunctive
relief; provided, however, that, in no event shall HSAC be entitled to terminate
or rescind this Agreement or enjoin, or otherwise interfere with the provision
of the Vulcan Content to Vulcan Systems, Independent Systems, and Subscribers as
contemplated hereunder.

                  9.2.3 Without limiting its other remedies at law or in equity
for any breach of this Agreement by HSAC, Vulcan may, in its sole discretion,
terminate this Agreement at any time and for any reason or no reason whatsoever
upon six (6) months written notice to HSAC.

                  9.2.4 HSAC and Vulcan each acknowledges that the rights
granted, and services to be provided to each other hereunder are of a special,
unique, unusual, extraordinary, and intellectual character, giving them peculiar
value, the loss of which 


                                      -12-
<PAGE>   13
cannot be reasonably or adequately compensated in damages; and that an actual or
threatened material breach by either party hereunder would cause the other party
irreparable injury and damage. Subject to Section 9.2.2 above, each party agrees
that, if it commits or is about to commit a material breach of this Agreement,
the other party will be entitled to injunctive or other equitable relief as a
remedy for any such actual or threatened material breach, without the
requirement to post any bond or other security therefor.

                  9.2.5 Neither party will be responsible for any delay or
failure in performance of any part of this Agreement, including without
limitation any delay or failure to provide Vulcan Content (in the case of
Vulcan) or any delay or failure to provide HSAC Services (in the case of HSAC),
to the extent that such delay or failure is caused by fire, flood, explosion,
war, lightning, embargo, government requirement, riots or civil commotion, acts
of civil or military authority, embargoes, strikes, acts of God, power surges,
acts or omissions of carriers or utilities, or other similar causes or
contingencies beyond its reasonable control.

         9.3 Effect of Termination. Upon termination, all licenses granted in 
Section 5.3 above will terminate, each party will return or destroy all
Confidential Information of the other party in its possession, HSAC's rights to
use, store, reproduce, and distribute Vulcan Content will terminate, and HSAC
will return to Vulcan all Vulcan Content, whether in electronic or
non-electronic form, and whether or not then in use by HSAC. If Vulcan has
supplied any Vulcan Equipment for HSAC use in providing Vulcan Content, Vulcan
may, in its sole discretion: (i) take possession of such Vulcan Equipment and
reimburse HSAC for reasonable expenses incurred in disconnecting the Vulcan
Equipment from the HSAC Network Equipment, (ii) offer the Vulcan Equipment to
HSAC at the fair market value, or (iii) if no market exists for the Vulcan
Equipment, offer the Vulcan Equipment to HSAC at a price equivalent to ten
percent (10%) over the salvage value.

                QUALITY CONTROLS AND RESTRICTIONS ON USE OF MARKS

         OWNERSHIP

         HSAC agrees and expressly acknowledges that nothing herein will give it
any right, title, or interest in the Vulcan Marks (except the right to use as a
licensee in accordance with the terms of this Agreement), that the Vulcan Marks
are the sole property of the Vulcan and its Affiliates and that any and all use
of the Vulcan Marks by HSAC inures to the benefit of the Vulcan and its
Affiliates.

         Vulcan agrees and expressly acknowledges that nothing herein will give
it any right, title, or interest in the HSAC Marks (except the right to use as a
licensee in accordance with the terms of this Agreement), that the HSAC Marks
are the sole property of HSAC, and that any and all use of the HSAC Marks by
Vulcan inures to the benefit of HSAC.

         Each party agrees not to raise or cause to be raised any questions,
claims or objections concerning the validity of the other party's title to its
Marks on any grounds whatsoever. Each party agrees it will do nothing
inconsistent with the ownership of the Marks by the other party, and agrees to
notify the other party of any unauthorized or inappropriate uses of the Marks of
which it becomes aware. Each party will provide reasonable assistance (at the
other party's expense) in any defense against challenges to the other party's
Marks, if requested to do so by the other party.

         If a party is required to register the Marks of the other party under
any statute for registration of fictitious business names or any other type of
registration, that party will notify the other party before registration, and
will only register in a form approved by the other party. Upon termination of
this Agreement, each party will immediately take all necessary steps to
eliminate any such registrations.

         SUBLICENSES

         Neither party will sublicense its right to use the Marks of the other
party under this Agreement without the prior written consent of that other
party, which may be withheld for any reason.

         RESTRICTIONS ON USE

         All uses of a party's Marks by the other party will be made together
with the appropriate ["(TM)"] ["(R)"] symbol in connection with the Marks.

         All uses of the Marks by a party will include a legend indicating that
each Mark is owned by its respective owner.

         Neither party will use any mark or device identical with or confusingly
similar to the licensed Marks of the other party in connection with any product
or service, except as permitted by this Agreement.
<PAGE>   22
         QUALITY CONTROL

         Each party agrees to use the Marks of the other party only in
connection with the lawful goods or services specified herein, and agrees that
such goods or services will be of a standard of quality at least as high as that
of similar goods or services produced by the other party. Each party alone will
judge, in its reasonable discretion, whether or not the other party has met or
is meeting the standards of quality so established.

         If at any time a party's products, packaging therefor, or services
associated with the Marks of the other party do not meet the quality standard
set forth herein, as reasonably determined by the other party, then that other
party will have the right to require discontinuation of the use of its Marks in
connection with the sale of such products or services, unless modifications
satisfactory to that party are made within ninety (90) days from notice of
disapproval.

         Each party will comply with all applicable laws and regulations and
obtain all appropriate governmental approvals pertaining to the sale,
distribution, and advertising of goods or services covered by this license.

         COSTS OF USING VULCAN MARKS

         HSAC will bear any and all costs associated with the use, printing, and
placing of the Vulcan Marks in materials prepared by HSAC in connection with
which HSAC has sought or is obliged to seek approval from Vulcan for the use of
the Vulcan Marks, and Vulcan will bear any and all costs associated with the
use, printing, and placing of the HSAC Marks in materials prepared by Vulcan in
connection with which Vulcan has sought or is obliged to seek approval from HSAC
for the use of the HSAC Marks.

2. EXCLUSIVE RIGHT TO PROVIDE HSAC SERVICES TO COMMITTED SYSTEMS; ADDITIONAL
COMMITTED SYSTEMS; INSPECTION AND ACCEPTANCE CRITERIA.

         2.1. Exclusive Access. During the Term, HSAC shall have the sole and
exclusive right to access the Committed Systems listed on EXHIBIT A to this
Agreement for purposes of performing the HSAC Services and to perform the HSAC
Services for the Committed Systems, subject to and in accordance with the terms
herein and the Systems Access Agreement. Subject to the procedures set forth in
this Section 2, HSAC shall perform a Full HSAC Services Roll-Out on every such
Committed System within the time frames specified for a particular Committed
System in the Activation Schedule.

         2.2. Designation of Additional Systems. During the Term (and subject to
the procedures set forth in this Section 2), Operator and Potential Operators
shall have the unilateral right, but not the obligation, to designate an
unlimited number of additional Cable Systems as Committed Systems under this
Agreement, and such right shall extend to any and all Cable Systems now owned or
managed or hereafter acquired or managed by Operator or Potential Operator.
Operator and Potential Operators shall exercise their right to designate
additional Cable Systems as Committed Systems hereunder by delivering written
notice of such designation to HSAC (an "Additional System Notice"). Upon HSAC's
receipt of such Additional System Notice, HSAC and the applicable Operator shall
amend this Agreement to add such Cable System(s) to EXHIBIT A, and the Cable
System(s) designated in such Additional System Notice shall automatically become
Committed Systems hereunder. If a Potential Operator designates Committed
Systems hereunder, the parties and such Potential Operators shall amend this
Agreement to include such Potential Operator as an Operator for all purposes
hereunder.

         2.3. Commissioning of RF Plant; System Data Requirements. Within sixty
(60) days of (i) the Effective Date (as to the Committed Systems referenced in
Section 2.1 above), and (ii) HSAC's receipt of an Additional System Notice (as
to the Committed Systems referenced in Section 2.2 above), HSAC shall perform an
engineering inspection of Operator's RF Plant in the applicable Committed
Systems and deliver to Operator, HSAC's recommendations for any upgrades or
repairs (if HSAC fails to deliver such recommendations for any Committed System
within such 60 day period, then such Committed Systems will be deemed to satisfy
the System Data Requirements) which may be necessary for the Committed System to
conform to System Data Requirements ("Attainment Measures"). Operator
acknowledges and agrees that (i) in order for HSAC to deliver HSAC Services to
Data Subscribers, each Committed System must satisfy the System Data
Requirements, (ii) HSAC is not responsible for whether the Committed Systems
satisfy the System Data Requirements, and (iii) Operator shall undertake (or
refuse to take, as the case may be) those Attainment 

                                     - 6 -
<PAGE>   7
Measures necessary to cause the Committed System's RF Plant to attain, and
thereafter maintain in conformity with, the System Data Requirements during the
Term of this Agreement. If the Operator declines to effect appropriate
Attainment Measures for any particular Committed System, this Agreement shall
terminate as to such Committed System without liability of any kind to either
Operator or HSAC, and such Committed System shall be removed from EXHIBIT A of
this Agreement. If the Operator agrees to effect the Attainment Measures, the
Activation Schedule shall be amended to establish the milestones for Operator to
bring the Committed Systems into conformity with the System Data Requirements
including a reasonable amount of additional time for HSAC to complete its Full
HSAC Services Roll-Out for such Committed Systems.

         2.4.     Activation Schedule.

                  2.4.1. The Activation Schedule for the initial Committed
Systems as of the Effective Date hereunder shall be as set forth in EXHIBIT A.
Within forty-five (45) days of HSAC's receipt of an Additional System Notice,
Operator and HSAC shall negotiate and agree in good faith upon a feasible,
reasonable "critical path" timelines for each Committed System's Full HSAC
Services Roll-Out, and memorialize such timeline in an Activation Schedule (as
same may be amended from time to time as contemplated in Section 2.3 above to
account for the Operator's taking of Attainment Measures and as the parties may
otherwise agree in writing). The Activation Schedule shall set out
implementation milestones, including, without limitation: (i) that Operator
shall notify HSAC when a particular Committed System conforms (or when the
Operator expects such Committed System to conform if the taking of Attainment
Measures is required) with the System Data Requirements, (ii) the Launch Date,
and (iii) the date when the Full HSAC Services Roll-Out in each Committed System
shall be completed. In the event that the parties cannot agree upon a reasonable
Activation Schedule for any additional Committed Systems designated under
Section 2.2 within forty-five (45) days of HSAC's receipt the applicable
Additional Systems Notice, then the provisions of Section 6.4 of the Systems
Access Agreement shall apply, and HSAC will implement the HSAC Services for such
additional Committed Systems at a rate of eight (8) head-ends per month (such
head-ends to be designated by Operator), with Operators' head-ends receiving
priority for activation over head-ends owned and/or operated by other customers
of HSAC.

                  2.4.2. HSAC will not be deemed in default of a scheduled
Launch Date if (i) a Regional Bell Operating Company ("RBOC") or other telephone
network provider (a "telco") is late in installing a T-1 line or backbone
connection necessary for the HSAC Services following the submission of a
complete order by HSAC to such party before the lead times required by such
party in order to install such T-1 line or backbone connection in sufficient
time to meet the applicable Launch Date, (ii) an equipment vendor (e.g., COM21)
fails to meet its delivery deadlines with respect to the HSAC Network Equipment
or Home Equipment Packages following the submission of a complete order by HSAC
to such party before the lead times required by such party in order to deliver
such equipment in sufficient 

                                     - 7 -
<PAGE>   8
time to meet the applicable Launch Date, or (iii) HSAC does not receive any
specialized equipment required to carry the Vulcan Content (as defined in the
Content Agreement), which equipment is otherwise not required in order to
perform the HSAC Services, on a timely basis following the submission of a
complete order by HSAC to the vendor of such equipment before the lead times
required by such vendor in order to deliver such equipment in sufficient time
for HSAC to meet the applicable Launch Date.

3. HSAC OBLIGATIONS AFTER COMMISSIONING. As soon as Operator notifies HSAC that
any head-end in a Committed System conforms to the System Data Requirements,
HSAC agrees that it shall in conformity with the Activation Schedule:

         3.1. install and connect the HSAC Network Equipment (subject to Section
6.2);

         3.2. arrange at its expense for data transport (via telco, wireless,
etc.) from the Internet backbone to the head-ends of Operator's RF Plant for a
Committed System;

         3.3. arrange telco return path circuits in One-Way Committed Systems;

         3.4.     commission the HSAC Network Equipment interface;

         3.5.     activate the data through-put portion of the HSAC Services;

         3.6. begin marketing HSAC Services in the relevant areas and begin
offering subscriptions to potential Data Subscribers; and

         3.7. complete the Full HSAC Services Roll-Out for such Committed System
and provide the HSAC Services for such Committed Systems.

4. UPGRADES. After initial activation of HSAC Services in a Committed System,
the Operator may reasonably request upgrades to the HSAC Network Equipment, and
HSAC shall make such upgrades at its expense within a reasonable time period,
provided that such upgrades are commercially reasonable. HSAC shall also make
substantially the same upgrades to the HSAC Network Equipment that HSAC makes to
substantially similar equipment that HSAC uses to provide HSAC or third party
customers access to the Internet. HSAC will provide Operator with all updates
and upgrades that HSAC develops or uses on any Cable System at the same prices
as such updates and upgrades are provided by HSAC to other customers of HSAC.
Neither party shall unilaterally change HSAC Network Equipment or Operator's RF
Plant in any way that renders a Committed System or the HSAC Services inoperable
without consulting with the other party regarding the allocation of costs
relating to such changes or upgrades.

5.       ALLOCATION OF MAINTENANCE OBLIGATIONS.

         5.1. Allocation. Following the commissioning of each Committed System,
HSAC shall maintain all HSAC Network Equipment. Operator shall maintain the
integrity of its RF 

                                     - 8 -
<PAGE>   9
Plant for each Committed System (including, without limitation, all coaxial
cable, head-end equipment, connectors, amplifiers and passive devices and
splitters). HSAC shall not be required to repair or maintain any portion of the
RF Plant of any Committed System. Operator shall also provide technical
personnel to eliminate signal leakage and maintain a proper connection interface
of the HSAC Network Equipment to the RF Plant for each Committed System.

         5.2. Damage to Operator's Facilities. HSAC shall use its best efforts
to avoid damaging the Operator's RF Plant for each Committed System, and shall
not move, relocate, alter, sell, lease, license, assign, encumber or otherwise
tamper with the RF Plant of any Committed Systems. Without limiting Operator's
rights and remedies, HSAC shall pay to repair or replace any of Operator's
equipment that HSAC or its employees damage and shall pay Operator for any
damages resulting therefrom. Such repairs shall return such Operator equipment
to at least the same condition it was before the damage, and any replacement
equipment will be at least the same quality as the Operator equipment that is
replaced.

         5.3. Damage to HSAC Network Equipment. The HSAC Network Equipment shall
be the property of HSAC. Operator shall use its best efforts to avoid damaging
the HSAC Network Equipment, and shall not move, relocate, alter, sell, lease,
license, assign, encumber or otherwise tamper with the HSAC Network Equipment.
Without limiting HSAC's rights and remedies, Operator shall pay to repair or
replace any of HSAC's equipment that Operator or its employees damage and shall
pay HSAC for any damages resulting therefrom. Such repairs shall return the HSAC
Network Equipment to at least the same condition it was before the damage, and
any replacement equipment will be at least the same quality as the HSAC Network
Equipment that is replaced.

6.       HOME EQUIPMENT PACKAGE.

         6.1. Equipment Choice. Operator and HSAC shall mutually choose the
vendor/brand* of HSAC Network Equipment and cable modems for each Committed
System, and HSAC shall procure the Home Equipment Packages for Data Subscribers
(except for Data Subscribers who purchase their own). Such Home Equipment
Packages shall be installed in accordance with Section 6.2 below. Upon
installation of such Home Equipment Packages, HSAC shall monitor and maintain
electronically the Home Equipment Package for each Data Subscriber. Unless
purchased directly by a Data Subscriber from Operator or a third party
reseller/retailer, HSAC shall retain ownership of the Home Equipment Packages.
Each Data Subscriber shall be required to sign a statement acknowledging HSAC's
ownership of the Home Equipment Package. (*For purposes of this Agreement,
Com2l, Terayon and any other brands the parties may from time to time agree upon
shall be deemed acceptable brands.)

         6.2. Installation And Modem Revenue Sharing. Either party may install
Home Equipment Packages or engage qualified third party installers to install
Home Equipment Packages for Data Subscribers. The party that installs Home
Equipment Packages shall keep 100% of the Installation Fee (which Installation
Fee will not exceed one hundred fifty dollars 

                                     - 9 -
<PAGE>   10


($150) per Data Subscriber). CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY
WITH THE COMMISSION. If HSAC rents any equipment that is part of the Home
Equipment Package to a Data Subscriber, then HSAC shall be entitled to retain
100% of such rentals up to a maximum of $14.95 per month per Data Subscriber,
and all rentals in excess of such amount will be divided equally between HSAC
and Operators. Nothing in this Section 6.2 shall limit Operator's ability to
charge and retain separate fees for connecting any Cable Subscriber's or Data
Subscriber's home to a Cable System or adding additional outlets in a Cable
Subscriber's or Data Subscriber's home.

7. ALLOCATION OF GENERAL OPERATIONAL RESPONSIBILITIES OF OPERATOR AND HSAC.
During the Term of this Agreement as to each Committed System, the following
provisions shall be applicable:

         7.1. Operator Responsibilities. Operator agrees to maintain its RF
Plants and facilities in the Committed Systems in conformity with industry
standards and the System Data Requirements set forth in EXHIBIT B for the
carriage of HSAC Services throughout the Committed Systems.

         7.2. HSAC Responsibilities. Following the commissioning of each
Committed System, in addition to the obligations set forth in Section 3.1 above,
HSAC agrees that it shall throughout the Term:

                  7.2.1. complete the Full HSAC Services Roll-Out and provide
the HSAC Services for Data Subscribers in the Committed Systems;

                  7.2.2. undertake and ensure that the HSAC Services, all HSAC
Network Equipment, and all software and services related to the HSAC Services
attain and maintain compliance with industry standards and the System Service
Requirements;

                  7.2.3. take all reasonable efforts to ensure that HSAC
Services are received only by Data Subscribers, and to take all reasonable
efforts to prevent unlawful reception, retransmission, or use of the HSAC
Services by any means, whether now known or hereafter devised, without the prior
written authorization of HSAC;

                  7.2.4. following activation of HSAC Services, control the flow
of data that it manages from the Committed Systems to the Internet Portal, and
HSAC shall be responsible for third-party software utilized to perform the HSAC
Services;

                  7.2.5. provide a toll-free telephone number and a Network
Operating Center ("NOC") and Customer Service Call Centers ("Call Center")

week basis (including weekends and holidays) via pager, cell phone, or similar
means ("24x7") with telephone support representatives to take calls from Data
Subscribers in the Committed System regarding Service Failures, the
operation/performance of the Home Equipment Package, and the Internet browser
and electronic mail software provided by third parties. HSAC shall answer all
such Data Subscriber calls with a greeting mutually agreed upon by the parties.
(Operator shall similarly provide HSAC with 24 x 7 "customer service response"
for the Committed System/RF portion of the HSAC Services.) HSAC shall make its
engineers and technicians available as needed to provide technical support and
to serve as liaisons between or among the Data Subscribers, Operator, and HSAC.

         7.3.     Certain Joint Responsibilities.  Operators and HSAC agree:

                  7.3.1. that if either party becomes aware that any
unauthorized party is receiving or transmitting any part of the HSAC Services,
then such party shall notify the other party in writing of the name and address
of such party if and when the first party actually knows the name and address of
such third party;

                  7.3.2. to exercise their commercially reasonable efforts to
maintain the secrecy of (and occasionally rotate) their software passwords, and
notify the other if they become aware that their system passwords may be or have
become compromised;

                  7.3.3. to comply with all applicable local, state and federal
laws, rules, regulation and franchises in all material respects;

                  7.3.4. to notify the other's NOC and Call Center promptly of
any material outages, interruptions, or degradation of service in either
Operator's RF Plant or the data portion of the HSAC Services (a "Service
Failure") of which they become aware from any source (i.e., a "Notice"). To the
extent a Service Failure is traceable to an RF Plant defect or malfunction
(whether or not due to Force Majeure), Operator shall provide technical
personnel within 4 hours (or on a commercially reasonable basis) of such Notice
to respond to such Service Failure and shall repair or replace any
malfunctioning equipment as soon as commercially practicable. To the extent the
Service Failure is traceable to HSAC Network Equipment or a data stream
malfunction, HSAC shall correct the Service Failure within 4 hours (or on a
reasonable commercial efforts basis) of such Notice or replace any
malfunctioning equipment as soon as commercially practicable; and

                  7.3.5. to cooperate and work together diligently to respond to
all Service Failures, and coordinate the scheduling of maintenance that might
interfere with the HSAC Services, provided that HSAC shall be responsible for
all NOC and customer service functions and requirements not related to the RF
Plant of Operator's Cable Systems. Both parties acknowledge that Service
Failure-related downtime, incorrect or inaccurate Data Subscriber invoicing, and
infrastructure problems shall be given highest priority attention at all times.
Operator and HSAC shall each have access to the other's NOC and Call Center on a

                                     - 11 -
<PAGE>   12
24x7 basis for the purpose of troubleshooting Service Failures pursuant to
agreed-upon Escalation Procedures, which are attached hereto as EXHIBIT C.

         7.4. Billing; End User Agreement. The procedure for processing
subscriptions for HSAC Services, the invoicing of Data Subscribers, and the
sharing of Gross Revenues shall be as set forth on EXHIBIT D attached hereto.
HSAC shall also distribute to and require Data Subscribers to sign an "End
User/Services Agreement" substantially in the form of EXHIBIT E attached hereto
which describes the limits placed on Data Subscribers' rights; provided, that
HSAC shall be under no obligation to enforce the terms of such End User/Services
Agreement.

         7.5. Data Subscriber Cancellation/Disconnect. In the event a Data
Subscriber terminates cable TV services with Operator and also cancels its
subscription to HSAC Services at the same time, Operator shall notify HSAC of
same and use its commercially reasonable efforts to recover and store (but does
not guarantee that it shall be able to recover), any rented Home Equipment
Package (except for the Ethernet card inside the customer's PC) for and on
behalf of HSAC. HSAC and Operator agree that in the event a Data Subscriber
cancels only its subscription to HSAC Services, HSAC shall likewise notify
Operator and be solely responsible for recovering any rented Home Equipment
Package.

         7.6.     Promotional and Build-Out Activities.

                  7.6.1. The parties shall cooperate reasonably with one another
regarding the marketing and promotion of HSAC Services to Cable Subscribers with
the aim of maximizing the number of Data Subscribers to the extent economically
feasible. Such cooperation shall include (i) at Operator's discretion,
installation of a "drop/install" at Operator's reasonable expense (may be passed
on to the Cable Subscriber) to any Home Passed, (ii) at HSAC's discretion,
Operator's installation of a "drop/install" for any commercial sites in a
Committed System for which HSAC will pay Operator's reasonable expenses (that
may be passed on to the commercial customer), and (iii) reasonable provision of
free advertising for the HSAC Services in the form of "ad avails" (i.e.,
advertising space which is not sold or committed to third parties that Operator
designates at its sole discretion as being available for advertising for HSAC
Services, "Charter Pipeline," "Marcus OnLine", "Charter Communications", "Marcus
Cable", or other brands as Operator may designate at its sole discretion) on
Operator's cable TV system, space in bills, statement messaging, and space in
installation packs. HSAC shall be responsible for the incremental expenses (if
any) associated with Operator's handling bill stuffers, space in bills,
statement messaging, and installation packs that are implemented at HSAC's
request. In addition, HSAC shall reimburse Operator for forty thousand dollars
($40,000) dollars annually in the aggregate expended by Operator for television
advertising to promote the Operator's Internet access brands under which HSAC
Services are provided.

                  7.6.2. All marketing and promotional materials, and any
materials that have an Operator owned or controlled trade or service mark on
them, will comply with the Quality 

                                     - 12 -
<PAGE>   13
Controls specified on EXHIBIT F hereto. Before any such materials prepared by
HSAC are used, HSAC will transmit a copy to Operator, and Operator will have
fifteen (15) days in which to reasonably reject such materials or to request
changes be made to such materials. If Operator does not respond to HSAC within
such fifteen (15) day period, such materials will be deemed approved for
distribution. All marketing and promotional materials will comply with the
branding provisions set forth in Section 7.6.5 below and shall be of a standard
of quality comparable to marketing and promotional materials prepared and
distributed by Operator. Operator grants to HSAC a worldwide, non-exclusive
royalty-free licensee to use and reproduce Operator's trademarks, service marks,
and brands and to distribute any marketing and promotional materials supplied to
HSAC by Operator (in Operator's sole discretion) for purposes of advertising and
marketing the HSAC Services in accordance with the terms and conditions hereof.

                  7.6.3. HSAC's marketing team will meet quarterly with each of
Operator's regional marketing teams and jointly review marketing plans,
strategy, and materials for each Committed System to assure acceptable quality
standards in accordance with the procedures in EXHIBIT I and Charter's current
Charter Pipeline Branding Guidelines. By October 31 of each calendar year during
the Term, HSAC shall also provide Operator with a copy of HSAC's marketing plan
(which when implemented shall substantially conform to Operator's approved
annual marketing plans for the following year), which Operator may approve or
reject in its reasonable discretion. The parties agree to confer and work
together to effect any appropriate revisions to HSAC's annual marketing plans
and materials, provided that Operator shall not be entitled to unilaterally
dictate HSAC's levels of marketing expenditures or HSAC's creative decisions or
choice or relative emphasis across various marketing channels, so long as the
foregoing shall not result in any detriment to or denigration of Operator's
brand image.

                  7.6.4. Subject to Section 7.8 below, Operator shall provide
HSAC access (both print copy and electronically at HSAC's expense) to its
Customer Lists and other customer databases on a confidential basis solely for
the purpose of developing and implementing HSAC's marketing plans, as well as
providing "On-Line Help-Desk" modem configuration support, Data Subscriber
sign-up, and ongoing customer service.

                  7.6.5.   Branding

                           (a) Without limiting HSAC's obligations under the
         Content Agreement, the parties agree that all HSAC Services (and all
         other Internet access and related services performed by HSAC within any
         Committed Systems' areas) shall be marketed, deployed, and supported in
         the Committed Systems only under the trademarks "Charter Pipeline,"
         "Marcus OnLine", "Charter Communications", "Marcus Cable" or other
         brands, service marks, and trademarks as Operator may designate.
         Operator shall be responsible for registering such brands, service
         marks, and trademarks and obtaining a matching or closely related
         domain name. Any such domain names shall be owned by the relevant
         Operator, or if they are temporarily 

                                     - 13 -
<PAGE>   14
         owned by HSAC, HSAC shall take all steps necessary promptly to transfer
         and assign such domain names to the relevant Operator.

                           (b) Subject to reasonable Operator oversight, HSAC
         shall produce and distribute all marketing materials and execute all
         marketing plans applicable to the HSAC Services. All marketing and
         promotional materials and any materials that have an Operator owned or
         controlled trademark on it shall comply with the Quality Controls
         specified in EXHIBIT F and before any such materials are used, a copy
         shall be sent to Operator, who shall have fifteen (15) days in which to
         reject such materials or to request changes be made to such materials.
         If Operator has not responded to HSAC within the fifteen (15) day
         period, such materials shall be deemed approved for distribution.

                           (c) Operator shall contribute reasonable ad avails
         (i.e., advertising space which is not sold or committed to third
         parties that Operator designates at its sole discretion as being
         available for advertising for HSAC Services, "Charter Pipeline,"
         "Marcus OnLine", "Charter Communications", "Marcus Cable", or other
         brands as Operator may designate at its sole discretion), space in
         bills, bill stuffers, statement messaging, and space in cable
         installation packs to promote the sales of subscriptions to HSAC
         Services to Cable Subscribers.

                           (d) Subject to all of the terms and conditions of
         this Agreement, if a Committed System is withdrawn from this Agreement,
         then HSAC shall be permitted to continue to use those trademarks,
         service marks, and brands owned by Operator that HSAC had been using
         for dial up Internet access services provided in such Committed System
         immediately before such Committed System was withdrawn from this
         Agreement for a six (6) month transition period but only for the dial
         up Internet access services provided within such Committed System's
         area.

                  7.6.6. Operator shall not be obligated to expand or upgrade
its RF Plants in the Committed Systems after a Launch Date. However, the parties
agree to jointly review and evaluate periodically the economic feasibility of
expanding or upgrading such RF Plants in order to increase the number of Homes
Passed and/or commercial Data Subscribers and to determine how such costs shall
be shared.

         7.7. Complimentary and Discounted Employee Accounts. HSAC shall at
Operator's direction provide to Homes Passed in each Committed System
complimentary HSAC Services accounts (except that, unless expressly set forth
below to the contrary, such recipients of complimentary service must pay for
their own Home Equipment Packages as would any other Data Subscriber) as
follows:

                  7.7.1. on a complimentary basis, up to five (5) transferable
accounts as designated by Operator;

                                     - 14 -
<PAGE>   15

                  7.7.2. on a complimentary basis, the greater of five (5)
additional government/"community service" accounts per Committed System or one
per franchise in each Committed System;

                  7.7.3. on a complimentary basis, the number of additional
accounts (complete with the modem/Home Equipment Package in this case only)
necessary for use within Operator's office(s) to support the HSAC Services (via
multiple modems or single-modem with hub/proxy server distribution as the
parties may agree);

                  7.7.4. such additional complimentary accounts as HSAC in its
sole discretion shall determine; and

                  7.7.5. on a fifty percent (50%) discount basis, additional
accounts for Operator's employees at their residences within a Committed System.

         7.8 Ownership of Customer Information. Notwithstanding anything to the
contrary set forth in this Agreement, the Data Subscribers and any Customer
Lists shall be deemed to be owned solely by, and shall be solely the property of
Operator, and all dial-up subscribers to the HSAC Services and related customer
lists shall be deemed to be owned solely by, and shall be solely the property
of, HSAC.

8. CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY WITH THE COMMISSION.


9. ENCRYPTION. HSAC may at its option make available security and encryption
equipment and/or software to Data Subscribers at no additional charge to
Operator; provided, that HSAC is not obligated to do so, nor shall Operator be
liable or responsible in any way for the installation and performance of such
equipment or software. HSAC represents and warrants that any such security and
encryption equipment and software will not interfere with the operation of the
Committed Systems in any way.

10.      CONFIDENTIAL INFORMATION.

         10.1. Confidentiality. Each party agrees that it shall not, during or
for a period of five (5) years after the Term of this Agreement, permit the
duplication, use, or disclosure of any Confidential Information to any person
(other than an employee, agent, or representative of the other party who must
have such information for the performance of its obligation hereunder), unless
such duplication, use or disclosure is specifically authorized by the other
party in writing. Each party shall (i) not disclose any Confidential Information
to any third person without the express written consent of the other party; (ii)
not use, directly, indirectly, or in concert with any other person, any
Confidential Information for any purpose other than 



                                     - 15 -
<PAGE>   16
the performance of their obligations under this Agreement; (iii) use reasonable
diligence, and in no event less than that degree of care which such party uses
in respect to its own Confidential Information of like nature, to prevent the
unauthorized disclosure or reproduction of such information. Without limiting
the generality of the foregoing, to the extent that this Agreement permits the
copying of Confidential Information, all such copies shall bear the same
confidentiality notices, legends, and intellectual property rights designations
that appear in the original versions.

         10.2. Exceptions. The confidentiality obligations set forth in Section
10.1 shall not be applicable to Confidential Information which is: (i) in the
public domain; (ii) known to the recipient party as of the date of this
Agreement as indicated by the recipient's written records, unless the recipient
party agreed to keep such information in confidence at the time of its receipt;
(iii) properly obtained hereafter from a source who is not under an obligation
of confidentiality with respect to such information; (iv) can be shown to have
been independently developed by the receiving party through persons who have not
had, either directly or indirectly, access or knowledge of such Confidential
Information; or (v) obligated to be produced by law, provided that any party
that is so ordered to produce Confidential Information shall give notice thereof
to the other party and cooperate reasonably with any attempt by the notified
party to enjoin its disclosure.

         10.3. Destruction of Data. Apart from HSAC's obligations to Operator
under this Section 10 concerning confidentiality, HSAC shall have no obligation
to delete or destroy Operator's information, including Operator's Customer Lists
or other Data Subscriber listings, from its computer systems or backup and
archival libraries until such time as HSAC's regular procedures for elimination
of such data would normally delete or destroy such information. Following a Data
Subscriber disconnect, Operator may require the elimination of its data
maintained within HSAC's backup and archival libraries prior to the time the
data would normally be deleted or destroyed by HSAC, and Operator shall pay for
reasonable expenses associated with the early deletion or destruction of all
such data.

11.      OWNERSHIP OF MARKS.

         11.1. HSAC Marks. Operator acknowledges that the names and marks "HSA,"
"HSAC," "HSA Network," "High Speed Access Network," "HSA Data Network," "Darwin
Networks," "CATV.net" and other HSAC logos, program names, trademarks, service
marks, programs, manuals, documentation, and other support materials covered by
this Agreement or otherwise used in connection with the HSAC Service, are the
exclusive property of HSAC. Operator has not and shall not acquire any
proprietary rights thereto by reason of this Agreement, and Operator shall have
no rights to use such names, marks, logos, variations or titles except at the
times and in a manner expressly approved by HSAC. Operator shall not publish or
disseminate any material that violates any restriction imposed by HSAC.

         11.2. Operator's Marks. Conversely, HSAC acknowledges that the names
and marks "Charter," "Charter Communications," "Charter Pipeline," "Charter
Mail," "Marcus 

                                     - 16 -

OnLine," and other Operator logos, program names, trademarks, service marks,
programs, manuals, documentation, host names, domain names, and other support
materials under which the HSAC Services shall be rolled-out under this Agreement
or otherwise used in connection with the HSAC Services, are the exclusive
property of Operator. HSAC has not and shall not acquire any proprietary rights
thereto by reason of this Agreement other than its contract rights hereunder,
and HSAC shall have no rights to use such names, marks, logos, variations or
titles except at the times and in a manner expressly approved by Operator. HSAC
shall not publish or disseminate any material that violates any restriction
imposed by Operator.

12. REPRODUCTION OF MANUALS AND DOCUMENTATION. Subject to the provisions of
Sections 10 and 11.1, Operator shall have the right, at no additional charge, to
reproduce solely for its internal use, all manuals and documentation furnished
by HSAC relating to the HSAC Services, regardless of whether such manual or
documentation is copyrighted by HSAC. All copies of manuals or documentation
made by Operator shall include any proprietary notice or stamp that has been
affixed by HSAC.

13.      REPRESENTATIONS AND WARRANTIES.

         13.1. HSAC hereby represents and warrants to Operator as follows:

                  13.1.1. HSAC is a corporation duly organized, validly existing

qualified to do business as a foreign corporation in all jurisdictions in which
it conducts its business.

                  13.1.2. HSAC's execution, delivery, and performance of this
Agreement and each of the Other Agreements have been duly authorized by all
requisite corporate action, and this Agreement and each of the Other Agreements
constitutes a legally valid and binding obligation of HSAC enforceable in
accordance with their terms, except as may be affected by laws relating to
bankruptcy or insolvency or the application by a court of equitable principles.

                  13.1.3. HSAC's execution, delivery, and performance of this
Agreement and each of the Other Agreements shall not violate, conflict with
and/or result in a breach or default under HSAC's certificate of incorporation,
bylaws or other charter documents, or any judgment, award, decree, agreement or
other instrument to which HSAC is a party.

                  13.1.4. No approval, authorization, consent, or order or
filing with any court, or governmental or administrative agency or any third
party is required in order for HSAC to enter into, deliver, and perform this
Agreement, each of the Other Agreements, and the transactions contemplated
herein and therein.

                  13.1.5. HSAC either owns or has properly licensed all rights
under patent, copyright, trademark, trade secret, and other domestic and foreign
intellectual property laws (collectively, "Intellectual Property Laws") that are
necessary or required to perform the Full HSAC Services Roll-Out, the HSAC
Services, and the other services to be performed by 



                                     - 17 -

HSAC hereunder and under the Network Agreements, including, without limitation,
all rights under Intellectual Property Laws relating to any equipment
(including, without limitation, the HSAC Network Equipment), software or Content
that HSAC shall use or shall provide in connection with the Full HSAC Services
Roll-Out, the HSAC Services, and the other services to be performed by HSAC
hereunder and under the Network Agreements. HSAC's provision and/or operation of
the Full HSAC Services Roll-Out, the HSAC Services, and the other services to be
performed by HSAC hereunder and under the Network Agreements shall not violate
or infringe any Intellectual Property Laws or violate or infringe any rights of
third parties.

                  13.1.6. To the best of its knowledge, HSAC has taken all
actions necessary and appropriate to assure that there shall be no material
adverse change to its business or electronic systems or material interruptions
in the operation and delivery of HSAC Service as provided in this Agreement
(aside from normal data packet delays, distortions, and losses (i) on the
Internet backbone, (ii) during transport to the Internet Backbone on
telecommunication lines leased from a third party, (iii) or during transport
from the customer to HSAC over a coaxial cable or fiber optic line) by reason of
the advent of the year 2000, including, without limitation, that all its
computer-based systems, embedded microchips and other data processing
capabilities have been designed or modified and fully tested in such a manner
that such computer-based systems, embedded microchips and other data processing
capabilities will not generate any invalid and/or incorrect date-related results
or cause any of the problems commonly referred to as "Year 2000 problems" and
will, without interruption or manual intervention, continue to operate
consistently, predictably and accurately and in accordance with all of the
requirements of this Agreement, including without limitation, meeting all
specifications and/or functionality and performance requirements, when used
during any year prior to, during or after the calendar year 2000. HSAC does not
warrant that interruptions in HSAC Service will not occur due to the network or
systems failures of other parties, including utilities and phone services,
caused by "Year 2000 problems."

         13.2. Each Operator hereby represents and warrants, severally, but not
jointly, and only as to itself, to HSAC as follows:

                  13.2.1. It is a corporation duly organized, validly existing,
and in good standing under the laws of its jurisdiction of incorporation and is
duly qualified to do business as a foreign corporation in all jurisdictions in
which it conducts its business.

                  13.2.2. Their execution, delivery, and performance of this
Agreement and each of the Other Agreements have been duly authorized by all
requisite corporate action, and this Agreement and each of the Other Agreements
constitutes a legally valid and binding obligation of each of them enforceable
in accordance with their terms, except as may be affected by laws relating to
bankruptcy or insolvency or the application by a court of equitable principles.

                  13.2.3. Their execution, delivery, and performance of this
Agreement and each of the Other Agreements shall not violate, conflict with
and/or result in a breach or default under their respective certificates of
incorporation, bylaws or other charter documents, or any judgment, award,
decree, agreement or other instrument to which either of them is a party.

                  13.2.4. No approval, authorization, consent, or order or
filing with any court, or governmental or administrative agency or any third
party is required in order for it to enter into, deliver, and perform this
Agreement, each of the Other Agreements and the transactions contemplated herein
and therein.

                  13.2.5. The franchise agreements with the various franchising
authorities with jurisdiction over the Committed Systems do not and will not
prohibit Operator from offering the HSAC Services directly or through HSAC under
this Agreement. Operator shall bear all costs associated with obtaining any such
"data over cable" franchise rights and authorizations (if so needed), pay any
franchise taxes related or applicable thereto, and indemnify HSAC with respect
to any such costs or taxes, whether or not retroactively assessed.

                  13.2.6. Operator either owns or has properly licensed all
rights under Intellectual Property Laws that are necessary or required to

shall not violate or infringe any Intellectual Property Laws or intellectual
property rights of third parties.

                  13.2.7. To the best of its knowledge, it has taken all actions
necessary and appropriate to assure that there shall be no material adverse
change to its business or electronic systems or material interruptions in the

intervention, continue to operate consistently, predictably and accurately and
in accordance with all of the requirements of this Agreement, including without
limitation, meeting all specifications and/or functionality and performance
requirements, when used during any year prior to, during or after the calendar
year 2000. Operator does not warrant that interruptions in HSAC Service will not
occur due to the network or systems failures of other parties, including
utilities and phone services, caused by "Year 2000 problems."

14.      INDEMNITY.

         14.1. HSAC will indemnify, defend, and hold harmless each Operator and
its respective affiliates, agents, successors, assigns, representatives,
officers, and directors from and against any liabilities, lawsuits, penalties,
claims, demands, awards, judgments, settlements, costs, and expenses (including,
without limitation, actual reasonable attorneys' fees and expenses on account
thereof) that arise or result from: (i) the breach by HSAC of any of its
representations, warranties, or covenants hereunder, (ii) HSAC's management,
operation, control or provision of the HSAC Services, or (iii) any violations of
any United States export control restrictions relating to the encryption
equipment and/or software made available by HSAC to Data Subscribers under
Section 9 above, including, without limitation, in any such case any
liabilities, lawsuits, penalties, or claims related to defamation, infringement,
criminal activities, and fraud, except to the extent that any such liabilities,
lawsuits, penalties, claims, demands, awards, judgments, settlements, costs or
expenses arise from such Operator's operation, management, and maintenance of
its RF Plant.

         14.2. Each Operator will severally, but not jointly, and only with
respect to its own acts or omissions, indemnify, defend, and hold harmless HSAC
and its affiliates, agents, successors, assigns, representatives, officers, and
directors from and against any liabilities, lawsuits, penalties, claims,
demands, awards, judgments, settlements, costs, and expenses (including, without
limitation, reasonable attorneys' fees and expenses on account thereof) that
arise or result from: (i) the breach by such Operator of any of its
representations, warranties or covenants hereunder, or (ii) such Operator's
operation, management, and maintenance of such Operator's RF Plant, including,
without limitation, in any such case, any liabilities, lawsuits, penalties, or
claims related to defamation, infringement, criminal activities, and fraud,
except to the extent that any such liabilities, lawsuits, penalties, claims,
demands, awards, judgments, settlements, costs or expenses arise from HSAC's
management, operation, control or provision of the HSAC Services.

         14.3. HSAC agrees to indemnify, defend, and hold harmless each Operator
and its respective affiliates, agents, successors, assigns, representatives,
officers, and directors, and each Operator agrees severally, but not jointly,
and only with respect to its acts or omissions, to indemnify, defend, and hold
harmless HSAC and its affiliates, agents, successors, assigns, representatives,
officers, and directors, from and against any liabilities, lawsuits, penalties,
claims, demands, awards, judgments, settlements, costs and expenses (including,
without limitation, reasonable attorneys' fees and expenses on account thereof)
that may be made for injuries, including death to persons, resulting from the
indemnifying party's negligent or willful acts or omissions or those of persons
employed by the indemnifying party, its agents, or subcontractors. Each Operator
and HSAC respectively agree to notify the other parties promptly of any written
claims or demands against the indemnified party for which the indemnifying party
is deemed responsible hereunder; provided, that, any failure to so notify shall
not affect the substantive rights hereunder.

15.      LIMITATION OF LIABILITY, INSURANCE.



                                     - 20 -
<PAGE>   21



         15.1. Limitation of Liability. EXCEPT FOR THE INDEMNIFICATION
OBLIGATIONS DETAILED IN SECTION 14 ABOVE, IN NO EVENT WILL EITHER PARTY HERETO
BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES (EVEN IF THAT PARTY HAD BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES), ARISING FROM OR RELATED TO A BREACH OF THIS AGREEMENT, INCLUDING
WITHOUT LIMITATION LOSS OF REVENUE OR ANTICIPATED PROFITS OR LOST BUSINESS.

         15.2. Insurance. At all times during the Term, HSAC shall maintain: (i)
appropriate policies of general liability, casualty, and business interruption
or disruption insurance, each with aggregate coverage of at least two million
dollars ($2,000,000) with commercially reasonable deductibles; (ii) appropriate
workers compensation insurance to cover HSAC's employees against injury to
themselves or others and casualty accidents while performing HSAC Services; and
(iii) appropriate insurance policies with at least two million dollars
($2,000,000) of coverage per incident with commercially reasonable deductibles
covering against claims for intellectual property infringement. All such HSAC
insurance policies shall name Operator as an additional insured party.

         15.3. Specific Performance. HSAC and Operator each acknowledges that
the rights granted, and services to be provided to each other hereunder are of a
special, unique, unusual, extraordinary, and intellectual character, giving them
peculiar value, the loss of which cannot be reasonably or adequately compensated
in damages, and that an actual or threatened material breach by either party
hereunder would cause the other party irreparable injury and damage. Subject to
Section 9.2.2 off the Content Agreement, each party agrees that, if it commits
or is about to commit a material breach of this Agreement, the other party will
be entitled to injunctive or other equitable relief as a remedy for any such
actual or threatened material breach, without the requirement to post any bond
or other security therefor.

16. TERM OF AGREEMENT. The term ("Term") of this Agreement shall commence on the
Effective Date, and as to a particular Committed System, continue for a term of
five (5) years thereafter from the Launch Date for each such Committed System
(the "Initial Term"). Following such Initial Term, this Agreement shall
automatically renew itself on a year-to-year basis (a "Renewal Term") unless
terminated by notice from either party at least three (3) months prior to the
expiration of the Initial Term or any such Renewal Term.

17.      [Intentionally Deleted]

18.      TERMINATION

         18.1. Operator Remedies. In addition to all of Operator's other rights
and remedies at law or equity, Operator has the right to (i) terminate this
Agreement, (ii) renegotiate this Agreement, (iii) remove a particular Committed
System from this Agreement, or (iv) retract HSAC's exclusive rights as to a
particular Committed System, if there has been a Termination Event as set forth
in Section 18.3 hereof. Operator's selection of any one of these remedies 

                                     - 21 -
<PAGE>   22
shall not preclude Operator from selecting any other of such remedies for the
same or other Termination Event. Except as set forth in Sections 18.6 and 19
below, in the event that a Termination Event occurs which is limited to a
particular Committed System, Operator may exercise the forgoing rights only with
respect to the Committed System in question and not this entire Agreement.

         18.2. Actions upon Termination. Except as set forth in Section 18.4 to
the contrary, upon any termination or cancellation of this Agreement as to a
particular Committed System for any reason whatsoever: (i) such Committed System
shall be removed from EXHIBIT A and from this Agreement, (ii) Operator shall
purchase from HSAC at book value (based on straight line depreciation) any
ownership rights that HSAC has in the HSAC Network Equipment, Home Equipment
Package, or any other equipment or software owned by HSAC that is committed to
such Committed System; (iii) HSAC shall comply with the Conversion Requirements
with respect to such Committed System; and (iv) HSAC shall transfer to Operator
all Confidential Information, Customer Lists, and any data related to or about
the Data Subscribers relating to the applicable Committed Systems.

         18.3. Termination Events. The following shall be deemed "Termination
Events:"

                  18.3.1. HSAC fails to meet Launch Date applicable to a
particular Committed System;

                  18.3.2. HSAC fails at any time to comply with the System
Service Requirements in any material respect and has not cured such lack of
compliance to Operator's reasonable satisfaction within sixty (60) after
Operator has provided HSAC with written notice of such non-compliance. Operator
shall have the right to at least once every three (3) months to reasonably audit
or observe HSAC's operations in order to determine if HSAC is complying with the
System Service Requirements;

                  18.3.3. There is a failure of the HSAC Services and/or the
HSAC Network Equipment such that the HSAC Services are not available to a
majority of Data Subscribers in a Committed System in the same manner as such
HSAC Services are normally available to such Data Subscribers, which failure is
not cured or repaired within thirty (30) days after Operator gives HSAC written
notice thereof;

                  18.3.4. HSAC becomes insolvent, or a petition under any
bankruptcy act shall be filed by or against HSAC (which petition shall not have
been dismissed within thirty (30) days thereafter), or HSAC executes an
assignment for the benefit of creditors, or a receiver is appointed for HSAC or
its assets, or HSAC takes advantage of any insolvency or any like statute;

                  18.3.5. HSAC fails to upgrade or replace any equipment or
software used in relationship with the HSAC Services such that such equipment no
longer complies with the 

                                     - 22 -
<PAGE>   23
vendor's standards and/or industry standards for such equipment, and such
failure is not cured within thirty (30) days after Operator gives written notice
thereof to HSAC;

                  18.3.6. HSAC shall fail to pay to Operator any and all sums
payable to Operator as and when due hereunder within thirty (30) days after
Operator gives HSAC written notice of such failure;

                  18.3.7. HSAC shall fail to carry, distribute and support the
Vulcan Content (as defined in the Content Agreement) on an exclusive basis for
all Cable Systems and other HSAC customers utilizing the HSAC Services in
accordance with the terms of the Content Agreement, HSAC shall carry any
Competing Content (as defined in the Content Agreement) in violation of the
Content Agreement, or HSAC shall breach the provisions of Section 6.3 of the
Content Agreement; and

                  18.3.8. CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY
WITH THE COMMISSION.

         18.4. Termination other than for a Termination Event. In addition to
Operators other rights and remedies hereunder, Operator shall have the right at
any time to withdraw any Committed System or terminate HSAC's exclusive rights
to provide HSAC Services with respect to any such Committed Systems for any
reason not covered in Sections 18.3, 18.6 and/or 19. If Operator does so, then
such Committed System shall be withdrawn from this Agreement, provided that (i)
Operator has provided ninety (90) days prior written notice, (ii) Operator pays
to HSAC the Termination Fee, (iii) Operator shall purchase from HSAC at book
value (based on straight-line depreciation) any ownership rights that HSAC has
in the HSAC Network Equipment and Home Equipment Package related to such
Committed System, and (iv) if such termination occurs within twelve (12) months
after the Launch Date with respect to a Committed System, Operator shall
reimburse HSAC for HSAC's actual, out-of-pocket marketing expenses paid by HSAC
with respect to such Committed System prior to date of termination.
Notwithstanding the foregoing, if Operator's withdrawal of a Committed System
from this Agreement under this Section 18.4 occurs as a result of Operator's
sale or other disposition of such Committed System, and the successor MSO or
other successor owner or operator of such Committed System assumes Operator's
obligations hereunder with respect to such Committed System, then Operator shall
not be obligated to comply with the provisions of subsections 18.4(ii), (iii)
and (iv) above in connection with such termination.

         18.5. Replacement of Committed Systems. If upon the removal of a
Committed System from this Agreement for any reason other than termination or
expiration of this Agreement, the aggregate number of Homes Passed in all
Committed Systems hereunder falls below 750,000, then Operators will designate
additional Cable Systems as Committed Systems hereunder such that the total
number of Homes Passed in all Committed Systems under this Agreement is not less

         18.6. Termination for Repeated Withdrawal of Committed Systems. In the
event that Operator withdraws from this Agreement pursuant to Section 18.1 above
(not including Committed Systems withdrawn pursuant to Section 18.4 above) a
number of Committed Systems equal to or greater than 50% of the total number of
Committed Systems initially included in Exhibit A to this Agreement as of the
Effective Date, then Operator shall have the right to terminate this Agreement
upon thirty (30) days prior written notice to HSAC, without any further
liability or obligation to HSAC.

19. EXCLUSIVITY TERMINATION. In addition to those reasons permitted elsewhere in
this Agreement, Operator may also terminate HSAC's exclusive rights under
Section 2.1 hereof if it is reasonably necessary to comply with any statutes,
regulations, or court orders.

20. INDEPENDENT CONTRACTORS. All work performed by HSAC in connection with the
HSAC Service described in this Agreement shall be performed by HSAC as an
independent contractor and not as the agent, employee, joint venture or partner
of Operator. All persons furnished by HSAC shall be for all purposes solely
HSAC's employees or agents and shall not be deemed to be employees of Operator
for any purpose whatsoever. HSAC shall furnish, employ, and have exclusive
control of all persons to be engaged in performing services under this Agreement
and shall prescribe and control the means and methods of performing such
maintenance services by providing adequate and proper supervision. Nothing
contained herein shall be deemed to create a relationship of joint venture,
associates, principal and agent or partnership between the parties hereto and
neither party shall hold itself out to the contrary. Each party is acting as
principal hereunder.

21. FORCE MAJEURE. Neither party shall be responsible for any Service Failure or
delay or failure in performance of any part of this Agreement to the extent that
such delay or failure is caused by fire, flood, explosion, war, lightning,
embargo, government requirement, riots or civil commotion, acts of civil or
military authority, embargoes, strikes, acts of God, power surges, acts or
omissions of carriers/utilities, or other causes or contingencies beyond its
reasonable control (a "Force Majeure"); provided, that (i) neither party shall
be relieved under this Section 21 from its obligations under Section 7 hereof
with respect to timely repairs of Service Failures caused by such Force Majeure,
and (ii) HSAC has complied with the manufacturers' or vendors' suggested
maintenance for any equipment used in providing the HSAC Services to the extent
such maintenance would have reduced the likelihood of or damage caused by any
Force Majeure. If any such event of Force Majeure occurs and such event
continues for ninety (90) days or more, the party delayed or unable to perform
shall give immediate notice to the other party, and the party affected by the
other's delay or inability to perform may elect to suspend performance of its
allocable portions or duties with respect to the HSAC Services for the duration
of the condition. The affected party may resume performance of its duties once
the condition ceases, and the period of this Agreement shall be deemed extended
for such affected Committed System up to the length of time the condition
endured.

22. ASSIGNMENT. HSAC shall not have the right to assign this Agreement to any
person or entity without the prior written consent of Operators, except that
HSAC may without Operator's consent assign its rights, but not its obligations,
to a subsidiary of HSAC, provided, that, no such assignment will relieve HSAC of
liability for its obligations hereunder. Operators may assign this Agreement to
any person or entity, and this Agreement shall be binding and inure to the
benefit of their successors and assigns. Each party shall be permitted to assign
this Agreement and grant a security interest in its contract rights and
tangible/intangible property interests (including the HSAC Network Equipment and
Home Equipment Packages) arising under this Agreement for purposes of securing
financing from its commercial lender(s). However, as a condition to doing so,
HSAC shall be obligated to obtain non-disturbance agreements in form and
substance satisfactory to Operators from each such lender under which such
lender agrees that, notwithstanding such lender's exercise of its rights as a
secured creditor, such lender and its assigns shall not disturb, affect or
interfere with HSAC's provision of the HSAC Services hereunder. All assignments
in contravention of this Section 22 shall be null and void and of no force or
effect. Either party shall provide the other party with thirty (30) days prior
written notice of any permitted assignment hereunder.

23. AMENDMENTS, MODIFICATIONS, OR SUPPLEMENTS. Amendments, modifications, or
supplements to this Agreement shall be permitted, provided all such changes
shall be in writing signed by the authorized representatives of both parties
unless otherwise expressly permitted in this Agreement, and all such changes
shall reference this Agreement and identify the specific articles or Sections of
this Agreement that is amended, modified, or supplemented.

<PAGE>   31
                                    EXHIBIT B

                         CABLE SYSTEM DATA REQUIREMENTS
                     (TECHNICAL REQUIREMENTS FOR RF PLANTS)

         1. HSAC shall inspect and characterize Operator's one-way and two-way
RF cable plant to determine its feasibility for digital data transmission for
One-Way or Two-Way cable modems. This characterization shall focus on the
integrity of the cable plant against interference, intermodal distortions,
ingress, system noise, and transient/impulse noise.

         2. HSAC has established guidelines for Operator wishing to implement
digital data transmission on their cable plant. The guidelines shall recommend
CATV plant and equipment configurations to achieve a desired level of signal
reliability and quality in digital data transmission.

         3. Operator's RF/cable network must possess at least 400 MHz of
bandwidth (with at least one (1) 6 MHz channel reserved and dedicated to HSAC
Service/data flow) and otherwise continuously meet the following minimum
performance standards, measured at designated end-of-line test points throughout
the cable plant. Although constituting on a sample of pertinent issues, the
following test points should be selected such that they are representative of
all areas of the cable distribution system. Each Committed System's head-end
must also pass at least 4,000 homes.

         4. HSAC shall issue a written report detailing the RF/cable network
deficiencies and recommendations for improvements, i.e., the Attainment
Measures.

                          ANALOG PERFORMANCE PARAMETERS

                  a. In-Band Frequency Amplitude Response - Frequency response
of the cable network indicates the variation of system gain as a function of
frequency measured in dB. As a general guideline the amplitude characteristic
shall be within a range of +/- 2 dB from 0.75 MHz to 5.0 MHz above the lower
boundary frequency of a cable television channel, referenced to the average of
the highest and lowest amplitudes within these frequency boundaries.

                  b. VISUAL CARRIER-TO-NOISE RATIO (CNR) - The guideline that
HSAC establishes for CNR values is in accordance with FCC specification
76.6059(a)(7) that defines the ratio of RF visual signal level to system noise
to be not less than 43 dB.

                  c. DISTORTIONS - Distortions are defined as the ratio of
visual signal level to RMS amplitude of any coherent disturbances such as
intermod products, second and third-order distortions or discrete frequency
interfering signals not operating on proper offset assignments. The guideline
which HSAC has established is defined by FCC specification 76.605(a)(8) and
specifies the following: (i) the ratio of visual signal level to coherent
<PAGE>   32
disturbances shall not be less than 51 dB for non-coherent channel cable
television systems, when measured with modulated carriers; and (ii) the ratio of
visual signal level to coherent disturbances which are frequency-coincident with
the visual carrier shall not-be less than 47 dB for coherent channel cable
systems, when measured with modulated carriers and time-averaged.

                  d. HUM MODULATION - This is the variation in the amplitude of
a CW carrier at the power line frequency of 60 Hz or its harmonics induced as a
result of passing through the cable network. The HSAC guideline is defined by
FCC regulation 76.605(a)(10), which requires that the peak-to-peak variation in
visual signal level caused by undesired low frequency disturbances (hum or
repetitive transients) generated within the system, or by inadequate low
frequency response, shall not exceed 3 percent.

                  e. INGRESS AND IMPULSE NOISE LEVELS - Ingress is the level of
unwanted ambient signals leaking into the CATV plant as a result of such things
as imperfect shielding, loose connectors, cracked cabling and other plant
defects. Impulse noise has different spectral characteristics, which invades
spectral power densities as the frequency increases. Causes of impulse noise
include AC arcing of electric motors, power utility transformers, electrostatic
discharges, lightning and other transient sources that can produce a loss of
synchronization on digital transmission systems. In characterizing plant
performance, HSAC guidelines dictate that impairments should be maintained,
collectively, at a nominal averaged level not to exceed -50 dBc with respect to
video carriers, while recognizing that noise becomes visible in the video domain
at -55 dBc and shall thus cause deterioration to optimum synchronization of the
data carrier. Further, to maintain optimal RF downstream efficiency, HSAC
specifies impairments that cause end-of-line Carrier-to-Noise (CNR) performance
to drop below a minimum constant value of 43 dB is unacceptable and shall result
in interrupted high-speed data access service to the customer.

                  f. GROUP DELAY RESPONSE DISTORTION - No standards are
currently defined that specify minimum performance for this parameter. HSAC
guidelines however specify that as a general rule, delay response over the
return path should match that over the forward path. It is recommended that the
return frequencies be located 6 MHz from either the upper of lower limits of the
return bandwidth. This shall help minimize any group delay associated with the
roll-up or roll-off of the return spectrum.

                  g. RETURN PLANT VISUAL CARRIER-TO-NOISE RATIO (CNR) - HSAC
guidelines specify a minimum 36 dB visual CNR over the forward plant, defining
40 dB CNR as the more ideal threshold parameter. The expected higher level of
noise sources in the return path is mitigated by the reduction of video and data
carriers on the upstream.

                  h. RETURN IN-BAND FREQUENCY AMPLITUDE RESPONSE DISTORTION -
HSAC guidelines are consistent with FCC specification 76.605(a)(6), requiring
that the amplitude characteristic of a video carrier in the return direction to
be within a range of +/- 2 dB from 0.75 MHz to 5.0 MHz should also apply to
reverse video transmission.
<PAGE>   33
                  i. DISTORTION - HSAC expects that the level of CSO and CTB
distortions on the return path* shall be generally lower than the forward path,
due to the limited number of RF video carriers interacting with each other in
this sub-low frequency spectrum. To maintain the integrity of the return path
data transmission, HSAC would generally not expect to see more than two video
carriers in this spectrum. Therefore, HSAC guidelines for distortions in the
return path follow the same FCC specification 76.605(a)(8) which applies to the
forward path, which is not less than 51 dB for standard CATV systems (modulated
carriers and time averaged).

                  j. SIGNAL AVAILABILITY- HSAC in cooperation with the Operator
shall jointly maintain the same goal of providing reliable, uninterrupted signal
transport over both the forward and reverse plant*. Cable maintenance practices
that routinely interrupt service must be discouraged, and HSAC requests that
Operator provide it with advance notice of any interruptive testing or
maintenance practice that could result in the disruption of signal flow in
either the forward or return path. This advance notice is required in order that
proper customer service levels can be adequately maintained. In extreme cases,
high speed data customers can be notified of possible service disruptions.

                  k. TESTING - HSAC and Operator jointly agree to periodically
test the forward and return RF paths* of the CATV system. Such testing is
required to document performance parameter thresholds to the extent that
high-speed data services are not adversely affected. In the absence of such
routine testing, Operator agrees to notify HSAC of any adverse irregular signal
level condition on the plant, intermittent or continuous, which persists longer
than a 12-hour interval.

* Applies only to 2-way cable plant high speed data solution. Single path, 1-way
hybrid high speed data solutions need not adhere to these specifications.

                    ESCALATION PROCEDURES FOR TROUBLESHOOTING

                                 TIER I SUPPORT

Tier I customer service/On-Line Help Desk is the "front line" of the HSA
Corp./MSO product offering. The responsibility of Tier I service is to provide
information to the customer, initiation and changes of service, billing
inquiries and some low-level trouble shooting, and frequently asked questions.
Tier I shall include the following:

- -        Start, stop and changes of service

- -        Determination of service eligibility

- -        Product information

- -        Billing and pricing questions

                                 TIER II SUPPORT

In the event that Tier I is not able to resolve any Service Failures or any Tier
I problems within twenty four (24) hours such Service Failure and Tier I
problems shall escalate to Tier II. Tier II customer service is the diagnostic
and problem resolution layer of the HSAC/MSO customer service offering. In this
layer, the symptoms of the problems are understood and recorded, the problem(s)
are determined and action is taken to resolve problem(s). This group shall have
advanced technical troubleshooting skills and tools. Support from this group
shall include:

- -        Desktop OS support.

- -        HSAC network information.

- -        HSAC delivered software support.

- -        Problem diagnosis and resolution.

- -        Build knowledge base and on-line information systems.

- -        Handle Wed and E-mail support.

                                TIER III SUPPORT

In the event that Tier II is not able to resolve any Service Failures or any
Tier II problems within forty eight (48) hours such Service Failure and Tier II
problems shall escalate to Tier III. Tier III shall provide customer service and
network operations support. This group shall handle any call not able to be
resolved by Tier II. In addition to resolving the more difficult customer
problems, this group shall be doing ongoing network monitoring. This
<PAGE>   35
group shall work twenty four (24) hours a day, seven (7) days a week with all
available personnel to resolve all Tier III problems.



         Notwithstanding the above, within 60 days of the Effective Date of this
Agreement, the parties will mutually agree to a written Escalation procedure
that will, include, without limitation, daily notification to Operators of all
customers experiencing an outage or trouble call as used in the Service
Requirements Exhibit beyond 24 hours.

                                    EXHIBIT D

                           REVENUE SPLITTING; BILLING

SPLITTING OF GROSS REVENUES.

         D.1 Base Payments for HSAC Services. During the Term of this Agreement
as to a particular Committed System, if Operator designates HSAC to handle
billing of Data Subscribers, HSAC shall pay to the Operator an amount (i.e.,
"Operator's Share") equal to the percentages, by service category, as shown in
TABLE A, of Gross Revenues. If Operator decides to handle billing of Data
Subscribers, it shall pay to HSAC an amount (i.e., "HSAC's Share") equal to 100%
of Gross Revenues minus the percentage Operator's Share, by service category, of
Gross Revenues as shown in TABLE A.


    CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY WITH THE COMMISSION.


         D.2 Data Subscriber Refunds. HSAC's local management shall have the
discretion to offer reasonable credits/refunds of Gross Revenues to Data
Subscribers resulting from Out-of-Compliance Events, which amounts shall be
deducted from the Operator's Share or added to HSAC's Share, as the case may be.
The determination of when Out-of-Compliance Events occur may be monitored and
reported by HSAC to the Operator on a monthly basis. As used herein, an
"Out-of-Compliance Event" occurs when the HSAC Services are rendered inoperable
or unusable due to the Committed Systems failing to meet System Data
Requirements or to a Service Failure traceable to the Operator's RF
Plant/Committed Systems (and such is not corrected within the period specified
in Section 7.3.4 of the Agreement) other than failures caused by a Force
Majeure.

         D.3 Settlement, Verification. Within thirty (30) days following the end
of each and every calendar month during the term thereof, the party handling
billing and collection shall deliver to the other party a statement (a
"Statement") showing the computation of the Operator's/HSAC's Share (derived
from the total number of Data Subscribers and Gross Revenues) in accordance with
this EXHIBIT E, which Statement shall specify amounts collected by region, and

CONDITIONS AND LIMITATIONS ON OPERATOR MARKS LICENSE

OWNERSHIP.

                           HSAC agrees and expressly acknowledges that nothing
herein shall give it any right, title, or interest in the Operator's trademarks,
service marks, and brands (except the right to use as a licensee in accordance
with the terms of this Agreement), that the Operator's Trademarks, service
marks, and brands are the sole property of the Operators and its affiliates and
that any and all use of the Operator's Trademarks, service marks, and brands by
HSAC inures to the benefit of the Operator and its affiliates.

                           HSAC agrees not to raise or cause to be raised any
questions, claims or objections concerning the validity of Operator's and/or its
affiliates' title to the Operator's Trademarks, service marks, and brands on any

and brands of which it becomes aware. HSAC shall provide reasonable assistance
(at Operator and its affiliates' expense) in any defense against challenges to
the Operator's trademarks, service marks, and brands, if requested to do so by
Operator and its affiliates.

judge, in its reasonable discretion, whether or not HSAC has met or is meeting
the standards of quality so established.

                           If at any time HSAC's products, packaging therefor,
or services associated with the Operator's trademarks, service marks, and brands
do not meet the quality standard set forth herein as reasonably determined by
Operator and its affiliates, Operator and its affiliates shall have the right to
require HSAC to discontinue the use of the Operator's trademarks, service marks,
and brands in connection with the sale of such products and/or services unless
modifications satisfactory to Operator and its affiliates are made within ninety
(90) days from notice of disapproval.

                           HSAC shall comply with all applicable laws and
regulations and obtain all appropriate governmental approvals pertaining to the
sale, distribution, and advertising of goods or services covered by this

         2.       Company Registration.

                  2.1 If the Company shall determine to register any of its
Common Stock for its own account or for the account of any other party, other
than a registration relating solely to employee benefit plans, or a registration
relating solely to a Rule 145 transaction, or a registration on any form of
registration statement that does not permit secondary sales, the Company will:

                           [a] promptly give to each Holder written notice
         thereof and of the anticipated effective date of such registration; and

                           [b] use its best efforts to include in such
         registration (and any related qualification under blue sky laws or
         other compliance), except as set forth in Section 2.2 below, and in any
         underwriting involved therein, all the Registrable Securities specified
         in a written request or requests made by any Holder and received by the
         Company within thirty (30) days after the written notice from the
         Company described in clause [a] above is mailed or otherwise delivered
         in accordance with this Agreement by the Company. Such written request
         may specify all or any part of a Holder's Registrable Securities.

                  2.2 Underwriting. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 2.1[a]. In such event, the right of any Holder to
registration pursuant to this Section 2 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such under writing
shall (together with the Company and the other holders of securities of the
Company with registration rights to participate therein distributing their
securities through such underwriting) enter into an underwriting agreement in
customary form with the representatives of the underwriter or underwriters
selected by the Company, including customary indemnification and contribution
agreements.

                  Notwithstanding any other provision of this Section 2, if the
lead representative of the underwriters advises the Company in writing that
marketing factors require a limitation on the number of shares to be
underwritten, the lead representative may (subject to the limitations set forth
below) exclude all Registrable Securities from, or limit the number of
Registrable Securities to be included in, the registration and underwriting. The
Company shall so advise all Holders of securities requesting registration, and
the number of shares of securities that are entitled to be included in the
registration and underwriting shall be allocated first to the Company for
securities being sold for its own account and thereafter as set forth in Section
10.

                  If any Holder does not agree to the terms of any such
underwriting, such Holder shall be excluded therefrom by written notice from the
Company or the lead representative of the underwriters. If shares are so
withdrawn from the registration and if the number of shares of Registrable
Securities to be included in such registration was previously reduced as a
result of

                                       3
<PAGE>   4




marketing factors, the Company shall then offer to all persons who have retained
the right to include securities in the registration the right to include
additional securities in the registration in an aggregate amount equal to the
number of shares of Registrable Securities so withdrawn, with such shares of
Registrable Securities to be allocated among the Holders requesting additional
inclusion in accordance with Section 10. Any Registrable Securities or other
securities excluded or withdrawn from such underwriting shall be withdrawn from
such registration.

         3.       Demand Registration.

                  3.1      Demand for Registration.

                  (A) If the Company shall receive from Initiating Holders at
any time or times following the completion by the Company of a Qualified Public
Offering (as defined below), a written request that the Company effect any
registration with respect to all or a part of the Registrable Securities, the
Company will:

                           [a] promptly give written notice of the proposed 
         registration to all other Holders; and

                           [b] as soon as practicable, and, in any event, within
         ninety (90) days after Company's receipt of a written request pursuant
         to this Section 3.1, use its best efforts to effect such registration
         (including, without limitation, filing post-effective amendments,
         appropriate qualifications under applicable blue sky or other state
         securities laws, and appropriate compliance with the Securities Act and
         any other governmental requirements or regulations) as would permit or
         facilitate the sale and distribution of all or such portion of such
         Registrable Securities as are specified in such request, together with
         all or such portion of the Registrable Securities of any Holder or
         Holders joining in such request as are specified in a written request
         received by the Company within thirty (30) business days after such
         written notice from the Company is mailed or otherwise delivered in
         accordance with this Agreement.

                           For purposes of this Agreement, a "Qualified Public
         Offering" shall mean the Company shall have completed an underwritten
         public offering of Common Stock , initiated by resolution of its Board
         of Directors, at a per share price of at least $7.50 (as proportion
         ately and appropriately adjusted to reflect any subdivision, reverse
         split or recapitalization of Common Shares after the date hereof) and
         not less than $50 million in aggregate gross proceeds to the Company
         which has been made pursuant to a registration statement filed with the
         Commission under the Securities Act.

                           The Company shall not be obligated to effect, or to
         take any action to effect, any such registration pursuant to this
         Section 3.1:

                                    [i] In any particular jurisdiction in which
                  the Company would be required to qualify to do business or
                  execute a general consent to service of process


                                       4

<PAGE>   5




                  in effecting such registration, qualification, or compliance,
                  unless the Company is already subject to service in such
                  jurisdiction and except as may be required by the Securities
                  Act;

                                    [ii] After the Company has initiated two
                  such registrations pursuant to this Section 3.1 (counting for
                  these purposes only registrations which have been declared or
                  ordered effective and pursuant to which Registrable Securities
                  requested by Initiating Holders to be included herein have
                  been sold);

                                    [iii] During the period starting with the
                  date sixty (60) days prior to the Company's good faith
                  estimate of the date of filing of a registration statement for
                  the account of the Company (other than in connection with a
                  Qualified Public Offering), and ending on a date ninety (90)
                  days after the effective date thereof;

                                    [iv] During the one hundred eighty (180) day
                  period following the effective date of a registration
                  statement of the Company filed under the Securities Act in
                  connection with a Qualified Public Offering.

                  (B) In addition, notwithstanding the foregoing provisions of
and without limiting the rights of any party hereto under Section 3.1(A), if the
Company shall not have completed a Qualified Public Offering on or before the
third anniversary of the date of this Agreement, then Vulcan Ventures,
Incorporated or its permitted assigns ("Vulcan") shall be entitled to request
that the Company effect a registration with respect to any portion of the
Registrable Securities then owned by it (so long as Vulcan or such assigns hold
not less than 25% of the Registrable Securities) and the Company shall use its
best efforts to effect such registration in accordance with the procedures set
forth in this Section 3. The Company shall not, however, be obligated to effect,
or to take any action to effect, any such registration pursuant to this Section
3.1(B) if the Board of Directors of the Company shall have resolved to file a
registration statement to effect a Qualified Public Offering and during the
sixty (60) days thereafter the Company shall have filed such registration
statement with the Securities and Exchange Commission.

                  3.2 Postponed Registration. Subject to clauses [i] through
[iv] of Section 3.1(A), the Company shall file a registration statement covering
the Registrable Securities requested pursuant to such section, or pursuant to
Section 3.1(B), to be registered as soon as practicable, but in any event within
ninety (90) days, after receipt of the request or requests of the Initiating
Holders; provided, however, that if (i) in the good faith judgment of the Board
of Directors of the Company, such registration would be seriously detrimental to
the Company and the Board of Directors of the Company concludes, as a result,
that it is essential to defer the filing of such registration statement at such
time, and (ii) the Company shall furnish to such Holders a certificate signed by
an executive officer of the Company stating that in the good faith judgment of
the Board of Directors of the Company, it would be seriously detrimental to the
Company for such registration statement to be filed in the near future and that
it is, therefore, essential to defer the filing of such registration statement,
then the Company shall have the right to defer such filing for a period of not
more than ninety (90) days after receipt of the request of the Initiating
Holders, and, provided further, that the

                                       5
<PAGE>   6




Company shall not defer its obligation in this matter more than once in any
eighteen month period. Notwithstanding the foregoing, nothing contained in this
Section 3.2 shall in any way restrict, reduce or postpone any registration right
of Vulcan provided in Section 3.1(B) of this Agreement.

                  The registration statement filed pursuant to the request of
the Initiating Holders may, subject to the provisions of this Section 3.2 and
Section 10 hereof, include other securities of the Company, with respect to
which registration rights have been granted, and may include securities of the
Company being sold for the account of the Company.

                  3.3 Underwriting. In connection with any underwriting effected
hereunder, the Company shall enter into such reasonable agreements (including
underwriting agreements) and make such representations and warranties and take
all such other actions in connection therewith in order to expedite or
facilitate the disposition of the Registrable Securities pursuant to any
applicable registration statement contemplated herein as may be reasonably
requested by any Holder in connection with any sale or resale pursuant to any
applicable registration statement. If any such Holder shall request that the
registration be in the form of a firm commitment underwritten offering, the
right of any such Holder to registration pursuant to Section 3 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein. In connection with a firm commitment underwritten
offering demanded by any Initiating Holder or Vulcan (pursuant to its right
under Section 3.1(B)), the Company shall: [i] upon request of any Holder,
furnish to each selling Holder and each underwriter, upon the effectiveness of
the registration statement (a) a certificate, dated such date, signed on behalf
of the Company by the principal executive officer of the Company, confirming, as
of the date thereof, that any preliminary prospectus or prospectus that is a
part of the registration statement as of their respective dates do not and will
not at any time contain an untrue statement of a material fact or omit to state
a material fact necessary, in light of the circumstances under which they were
made, not misleading, (b) an opinion of counsel for the Company covering matters
customarily set forth in an underwriting agreement for firm commitment
underwritten offerings, (c) a comfort letter from the Company's independent
accountants, in the customary form and covering matters of the type customarily
covered by comfort letters to underwriters in connection with firm commitment
underwritten offerings and (d) deliver such other documents and certificates as
may be reasonably requested by the selling Holders or the lead representative of
the underwriters in connection with such firm commitment underwritten offering.
A Holder may elect to include in such underwritten offering all or a part of the
Registrable Securities such Holder holds.

                  3.4 Procedures. If the Company shall request inclusion in any
registration pursuant to Section 3 of securities being sold for its own account,
or if other persons shall request inclusion in any registration pursuant to
Section 3, the Initiating Holders or Vulcan (pursuant to its right under Section
3.1(B)) shall, on behalf of all Holders, offer to include such securities in the
underwritten offering and may condition such offer on their acceptance of the
further applicable provisions of this Agreement. In connection with an
underwritten offering hereunder, the Company shall (together with all Holders
and other persons proposing to distribute their securities through such
underwritten offering) enter into an underwriting agreement in customary form
(including customary indemnification and contribution provisions) with the lead
representative of the

                                       6
<PAGE>   7




underwriter or underwriters selected for such underwriting by the Company, which
underwriters are reasonably acceptable to a majority in interest of the
Initiating Holders or Vulcan (pursuant to its right under Section 3.1(B)).
Notwithstanding any other provision of this Section 3, if the lead
representative of the underwriters advises the Initiating Holders in writing
that marketing factors require a limitation on the number of shares to be
included in such underwritten offering, the number of shares to be included in
the underwritten offering shall be allocated as set forth in Section 10 hereof.
If a Holder who has requested inclusion in such registration as provided above
does not agree to the terms of any such underwritten offering, such Holder shall
be excluded therefrom by written notice from the Company, the lead
representative of the underwriters or the Initiating Holders. If shares are so
excluded from the registration and if the number of shares of Registrable
Securities to be included in such registration was previously reduced as a
result of marketing factors pursuant to this Section 3.4, then the Company shall
offer to all Holders who have retained rights to include Registrable Securities
in the registration the right to include additional Registrable Securities in
the registration in an aggregate amount equal to the number of shares of
Registrable Securities so excluded, with such shares of Registrable Securities
to be allocated among such Holders requesting additional inclusion in accordance
with Section 10.

         4. Registration Expenses. All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Sections 2 and 3 hereof shall be borne by the Company. All Selling Expenses
relating to securities so registered shall be borne by the Company, except that
in no event shall the Company be responsible for payment of the underwriters'
discount and/or selling commissions in connection with the registration of the
Registrable Securities of any of the Holders.

         5. Registration Procedures. In the case of each registration effected
by the Company pursuant to this Agreement, the Company will keep each Holder
advised in writing as to the initiation of each registration and as to the
material progress and completion thereof. At its expense, the Company will use
its best efforts to:

                  5.1 Keep such registration effective for a period of one
hundred eighty (180) days or until the Holder or Holders have completed the
distribution described in the registration statement relating thereto; provided,
however, that such 180-day period shall be extended for a period of time equal
to the period the Holder refrains from selling any securities included in such
registration at the request of an underwriter of Common Stock (or other
securities of the Company);

                  5.2 Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus made a part of
such registration statement as may be necessary to comply with the provisions of
the Securities Act with respect to the disposition of all securities covered by
such registration statement;

                  5.3 Furnish such number of prospectuses and other documents
incident thereto, including any amendment of or supplement to the prospectus, as
a Holder from time to time may reasonably request;


                                       7
<PAGE>   8




                  5.4 Cause all such Registrable Securities registered pursuant
hereunto to be listed on each securities exchange, if any, on which similar
securities issued by the Company are then listed and comply with all applicable
blue sky laws to enable the Registrable Securities to be publicly offered and
sold in the states in which such Registrable Securities will be offered;

                  5.5 Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to such registration statement and a CUSIP number
for all such Registrable Securities, in each case not later than the effective
date of such registration;

                  5.6 Advise the selling Holders promptly and, if requested by
such Holders, confirm such advice in writing, (i) when the prospectus or any
prospectus supplement or post-effective amendment has been filed, and, with
respect to any applicable registration statement or any post-effective amendment
thereto, when the same has become effective, (ii) of any request by the
Commission for amendments to the registration statement or amendments or
supplements to the prospectus or for additional information relating thereto,
(iii) of the issuance by the Commission of any stop order suspending the
effectiveness of the registration statement under the Securities Act or of the
suspension by any state securities commission of the qualification of the
Registrable Securities for offering or sale in any jurisdiction, or the
initiation of any proceeding for any of the preceding purposes, or (iv) of the
existence of any fact or the happening of any event that makes any statement of
a material fact made in the registration statement, the prospectus, any
amendment or supplement thereto or any document incorporated by reference
therein untrue, or that requires the making of any additions to or changes in
the registration statement in order to make the statements therein not
misleading, or that requires the making of any additions to or changes in the
Prospectus in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. If at any time the
Commission shall issue any stop order suspending the effectiveness of the
registration statement, or any state securities commission or other regulatory
authority shall issue an order suspending the qualification or exemption from
qualification of the Registrable Securities under state securities or blue sky
laws, the Company shall use its best efforts to obtain the withdrawal or lifting
of such order at the earliest possible time;

                  5.7 Furnish to each selling Holder named in any registration
statement or prospectus in connection with such sale, if any, before filing with
the Commission, copies of any registration statement or any prospectus included
therein or any amendments or supplements to any such registration statement or
prospectus (including all documents incorporated by reference after the initial
filing of such registration statement), which documents will be subject to the
review and comment of such Holders in connection with such sale, if any, for a
period of at least three business days, and the Company will not file any such
registration statement or prospectus or any amendment or supplement to any such
registration statement or prospectus (including all such documents incorporated
by reference) to which the selling Holders of the Registrable Securities covered
by such registration statement in connection with such sale, if any, shall
reasonably object within three business days after the receipt thereof. A
selling Holder shall be deemed to have reasonably objected to such filing if
such registration statement, amendment, prospectus or supplement, as applicable,
as proposed to be filed, contains a material misstatement or omission or fails
to comply with the applicable requirements of the Securities Act;

                                       8
<PAGE>   9




                  5.8 Promptly prior to the filing of any document that is to be
incorporated by reference into a registration statement or prospectus, provide
copies of such document to the selling Holders in connection with such sale, if
any, make the Company's representatives available for discussion of such
document and other customary due diligence matters, and include such information
in such document prior to the filing thereof as such selling Holders may
reasonably request;

                  5.9 Make available at reasonable times for inspection by the
selling Holders participating in any disposition pursuant to such registration
statement and any attorney or accountant retained by such selling Holders, all
financial and other records, pertinent corporate documents of the Company and
cause the Company's officers, directors and employees to supply all information
reasonably requested by any such selling Holder, attorney or accountant in
connection with such registration statement or any post-effective amendment
thereto subsequent to the filing thereof and prior to its effectiveness;

                  5.10 If requested by any selling Holders in connection with
such sale, if any, promptly include in any registration statement or prospectus,
pursuant to a supplement or post-effective amendment if necessary, such
information as such selling Holders may reasonably request to have included
therein, including, without limitation, information relating to the "Plan of
Distribution"; and make all required filings of such prospectus supplement or
post-effective amendment as soon as practicable after the Company is notified of
the matters to be included in such prospectus supplement or post-effective
amendment;

                  5.11 Furnish to each selling Holder upon their reasonable
request in connection with such sale, if any, without charge, at least one copy
of the registration statement, as first filed with the Commission, and of each
amendment thereto, including all documents incorporated by reference therein and
all exhibits (including exhibits incorporated therein by reference);

                  5.12 Prior to any public offering of Registrable Securities,
cooperate with the Holders and their counsel in connection with the registration
and qualification of the Registrable Securities under the securities or blue sky
laws of such jurisdictions as the selling Holders may request and do any and all
other acts or things reasonably necessary or advisable to enable the disposition
in such jurisdictions of the Registrable Securities covered by the applicable
registration statement; provided, however, that the Company shall not be
required to register or qualify as a foreign corporation where it is not now so
qualified or to take any action that would subject it to the service of process
in suits or to taxation, other than as to matters and transactions relating to
the registration statement, in any jurisdiction where it is not now so subject;

                  5.13 Use its reasonable best efforts to cause the disposition
of the Registrable Securities covered by the registration statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to enable the seller or sellers thereof to consummate the
disposition of such Registrable Securities;


                                       9
<PAGE>   10




                  5.14 Comply with all applicable rules and regulations of the
Commission, and make generally available to all Holders with regard to any
applicable registration statement, as soon as practicable, a consolidated
earnings statement meeting the requirements of Rule 158 (which need not be
audited) covering a twelve-month period beginning after the effective date of
the registration statement (as such term is defined in paragraph (c) of Rule 158
under the Securities Act); and

                  5.15 Make appropriate officers of the Company available to the
selling Holders for meetings with prospective purchasers of the Registrable
Securities and prepare and present to potential investors customary "road show"
material in a manner consistent with other new issuances of other securities
similar to the Registrable Securities.

         6.       Indemnification.

                  6.1 The Company will indemnify each Holder, each of its
officers, directors and partners, legal counsel, and accountants and each person
controlling such Holder within the meaning of Section 15 of the Securities Act
and each underwriter, if any, and each person who controls within the meaning of
Section 15 of the Securities Act any underwriter, with respect to which
registration, qualification, or compliance has been effected pursuant to this
Agreement, against all expenses, claims, losses, damages, and liabilities (or
actions, proceedings, or settlements in respect thereof), arising out of or
based on any untrue statement (or alleged untrue statement) of a material fact
contained in any prospectus, offering circular, or other document (including any
related registration statement, notification, or the like) incident to any such
registration, qualification, or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the
Company of the Securities Act or any rule or regulation thereunder applicable to
the Company and relating to action or inaction required of the Company in
connection with any such registration, qualification, or compliance, and will
reimburse each such Holder, each of its officers, directors, partners, legal
counsel, and accountants and each person controlling such Holder, each such
underwriter, and each person who controls any such underwriter, for any legal
and any other expenses reasonably incurred in connection with investigating and
defending or settling any such claim, loss, damage, liability or action, as such
expenses are incurred, provided that the Company will not be liable in any such
case to the extent that any such claim, loss, damage, liability, or expense
arises out of or is based on any untrue statement or omission based upon written
information furnished to the Company by such Holder or underwriter and stated to
be specifically for use therein. It is agreed that the indemnity agreement
contained in this Section 6.1 shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the written consent of the Company (which consent has not been
unreasonably withheld). The foregoing indemnity agreement is in addition to any
liability which the Company may otherwise have to any Holder or any such
director, officer, partner, legal counsel, accountant, underwriter or control
person.

                  6.2 Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification, or compliance is being effected, indemnify the Company, each of
its directors, officers, partners, legal counsel, and accountants and each
underwriter, if any, of the Company's securities covered by such a registration
statement, each

                                       10
<PAGE>   11




person who controls the Company or such underwriter within the meaning of
Section 15 of the Securities Act, each other such Holder, and each of their
officers, directors, and partners, and each person controlling such Holder,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular, or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company and such Holders, directors, officers, partners, legal counsel, and
accountants, persons, underwriters, or control persons for any legal or any
other expenses reasonably incurred in connection with investigating or defending
any such claim, loss, damage, liability, or action, in each case to the extent,
but only to the extent, that such untrue statement (or alleged untrue statement)
or omission (or alleged omission) is made in such registration statement,
prospectus, offering circular, or other document in reliance upon and in
conformity with written information furnished to the Company by such Holder and
stated to be specifically for use therein provided, however, that the
obligations of such Holder hereunder shall not apply to amounts paid in
settlement of any such claims, losses, damages, or liabilities (or actions in
respect thereof) if such settlement is effected without the written consent of
such Holder (which consent shall not be unreasonably withheld); and provided,
however, that in no event shall any indemnity under this Section 6.2 exceed the
gross proceeds from the offering received by such Holder with respect to its
sale of Registrable Securities pursuant to the prospectus less the amount of any
damages that such Holder has otherwise been required to pay by reason of such
untrue statement or alleged untrue statement or omission or alleged omission.
The foregoing indemnity agreement is in addition to any liability which the
Holder may otherwise have to the Company or any such director, officer, partner,
legal counsel, accountant, underwriter or control person.

                  6.3 Promptly after receipt by an indemnified party under
paragraphs 6.1 or 6.2 above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such paragraph, notify each party against whom
indemnification is to be sought in writing of the commencement thereof (but the
failure so to notify an indemnifying party shall not relieve it from any
liability which it may have under this Section 6). In case any such action is
brought against any indemnified party, and it notifies an indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein, and to the extent it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel satisfactory to
such indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such
case, but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by one of the indemnifying parties in connection
with the defense of such action, (ii) the indemnifying parties shall not have
employed counsel to have charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them which are different from or additional to those
available to one or all of the indemnifying parties (in which case the
indemnifying parties shall not have the right to direct the defense of such
action on behalf of the indemnified party

                                       11
<PAGE>   12




or parties), in any of which events such fees and expenses shall be borne by the
indemnifying parties. Anything in this subsection to the contrary
notwithstanding, an indemnifying party shall not be liable for any settlement or
any claim or action effected without its written consent; provided, however,
that such consent was not unreasonably withheld.

                  6.4 If the indemnification provided for in this Section 6 is
for any reason unavailable to an Indemnified Party with respect to any loss,
liability, claim, damage, or expense referred to herein, then the Indemnifying
Party, in lieu of indemnifying such Indemnified Party hereunder, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such loss, liability, claim, damage, or expense in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party on the one
hand and of the Indemnified Party on the other in connection with the statements
or omissions of the Indemnifying Party and of the Indemnified Party. Such
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission to
state a material fact relates to information supplied by the Indemnifying Party
or by the Indemnified Party and the parties' relative intent, knowledge, access
to information, and opportunity to correct or prevent such statement or
omission; provided that in no event shall contribution by the Holder under this
Section 6.4 exceed the gross proceeds from the offering received by the Holder.

                  6.5 Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten offering are in
conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

         7. Information by Holder. Each Holder of Registrable Securities shall
furnish to the Company such information regarding such Holder and the
distribution proposed by such Holder as the Company may reasonably request in
writing and as shall be reasonably required in connection with any registration,
qualification, or compliance referred to in this Agreement.

          8. Transfer or Assignment of Registration Rights. The rights to cause
the Company to register securities granted to a Holder by the Company under
Section 2 or the right to demand that the Company register securities granted
under Section 3 may be transferred or assigned by a Holder only to a transferee
or assignee of not less than 10,000 shares of Registrable Securities (as
presently constituted and subject to subsequent adjustments for stock splits,
stock dividends, reverse stock splits, and the like); provided, however, that
the Company is given written notice at the time of or within a reasonable time
after said transfer or assignment, stating the name and address of the
transferee or assignee and identifying the securities with respect to which such
registration rights are being transferred or assigned, and, provided further,
that the transferee or assignee of such rights assumes in writing the
obligations of such Holder under this Agreement.

         9. "Market Stand-Off" Agreement. If requested by the Company and the
lead representative of the underwriters of Common Stock (or other securities of
the Company), no officer, director, holder of more than five percent (5%) of the
outstanding capital stock of the Company or Holder shall sell or otherwise
transfer or dispose of any Common Stock (or other securities) of the

                                       12
<PAGE>   13




Company held by such Holder (other than those included in the registration)
during a period of up to ninety (90) days following the effective date of a
registration statement of the Company filed under the Securities Act, provided
that such agreement shall only apply to the first such registration statement of
the Company that includes securities to be sold on its behalf to the public in
an underwritten offering.

                  The obligations described in this Section 9 shall not apply to
a registration relating solely to employee benefit plans on Form S-1 or Form S-8
or similar forms that may be promulgated in the future, or a registration
relating solely to a Rule 145 transaction on Form S-4 or similar forms that may
be promulgated in the future. The Company may impose stop-transfer instructions
with respect to the shares (or securities) subject to the foregoing restriction
until the end of said one hundred eighty (180) day period.

         10. Allocation of Registration Opportunities. In any circumstance in
which all of the Registrable Securities and other shares of Common Stock with
registration rights (the "Other Shares") requested to be included in a
registration on behalf of the Holders or other selling stockholders cannot be so
included as a result of limitations of the aggregate number of shares of
Registrable Securities and Other Shares that may be so included, the number of
shares of Registrable Securities and Other Shares that may be so included shall
be allocated among the Holders and other selling stockholders requesting
inclusion of shares pro rata on the basis of the number of shares of Registrable
Securities and Other Shares that would be held by such Holders and other selling
stockholders. If any Holder or other selling stockholder does not request
inclusion of the maximum number of shares of Registrable Securities and Other
Shares allocated to him pursuant to the above-described procedure, the remaining
portion of this allocation shall be reallocated among those requesting Holders
and other selling stockholders whose allocations did not satisfy their requests
pro rata on the basis of the number of shares of Registrable Securities and
Other Shares that would be held by such Holders and other selling stockholders
and this procedure shall be repeated until all of the shares of Registrable
Securities and Other Shares which may be included in the registration on behalf
of the Holders and other selling stockholders have been so allocated. The
Company shall not limit the number of Registrable Securities to be included in a
registration pursuant to this Agreement in order to include shares held by
stockholders with no registration rights.

         11. Limitations on Registration of Other Securities; Representation.
From and after the date of this Agreement, the Company shall not, without the
prior written consent of a majority in interest of the Holders, enter into any
agreement with any holder or prospective holder of any securities of the Company
giving such holder or prospective holder any registration rights the terms of
which are as or more favorable than registration rights granted to the Holders
hereunder unless the Company shall also give such favorable rights to the
Holders hereunder. Except for certain registration rights granted to certain
holders of the Company's Common Shares pursuant to the Registration Rights
Agreement dated February 23, 1998 among CATV.net, Inc. and certain others, which
provisions are incorporated herein by this reference, are adopted and affirmed
by the Company as of the date hereof, and shall survive the integration
provisions of Section 14.3 below, the Company represents and warrants as of the
date hereof that there is no other agreement existing

                                       13
<PAGE>   14




giving any other person or entity any registration rights with respect to any
securities of the Company.

         12.      Reporting.

                  12.1 The Company agrees when required by law to make and keep
public information available, as those terms are understood and defined in Rule
144, at all times after ninety (90) days after the effective date of the first
registration filed by the Company for an offering of its securities to the
general public.

                  12.2 The Company will use its best efforts to file with the
Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the Exchange Act.

                  12.3 The Company will provide written evidence of compliance
with Section 12.1 and the filing of all reports contemplated by Section 12.2 to
a Holder promptly upon receipt of a written request for such evidence from such
Holder.

         13. Termination of Registration Rights. The right of any Holder to
request registration or inclusion in any registration pursuant to Section 2
shall terminate on the closing of the first Company initiated registered public
offering of Common Stock if all shares of Registrable Securities held or
entitled to be held upon conversion by such Holder may immediately be sold under
Rule 144 during any 90-day period, or on such date after the closing of the
first Company initiated registered public offering of Common Stock if all shares
of Registrable Securities held or entitled to be held upon conversion by such
Holder may immediately be sold under Rule 144 during any 90-day period;
provided, however that the provisions of this Section 13 shall not apply to any
Holder who owns more than five percent (5%) of the Company's outstanding stock
until such time as such Holder owns less than five percent (5%) of the
outstanding stock of the Company.

         14.      Miscellaneous.

                  14.1 Governing Law. This Agreement shall be governed in all
respects by the laws of the State of Delaware without giving effect to the
principles of conflicts of laws thereof.

                  14.2 Successors and Assigns. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
the parties hereto.

                  14.3 Entire Agreement; Amendment; Waiver. This Agreement
amends and restates in its entirety the Amended and Restated Registration Rights
Agreement dated as of September 1, 1998 among the Company, Broadband Solutions,
LLC and Broadband Solutions II, LLC. This Agreement constitutes the full and
entire understanding and agreement between the parties with regard to the
subjects hereof. Neither this Agreement nor any term hereof may be amended,
waived, discharged or terminated, except with the consent of the holders of a
majority of each class or series

                                       14
<PAGE>   15




of the then outstanding Preferred Stock voting as a separate class or series
(with each share having one vote), and any such amendment, waiver, discharge or
termination shall be binding on all the Holders, but in no event shall the
obligation of any Holder hereunder be materially increased, except upon the
written consent of such Holder.

                  14.4 Notices. All notices, requests, consents, and other
communications under this Agreement shall be in writing and shall be mailed by
first class, registered, or certified mail, postage prepaid, or sent via
overnight reputable courier service, or delivered personally or via facsimile

are customarily performed by one holding the position of Chief Executive Officer
of a company comparable to the Company, and to perform such other duties as may
be assigned to him by the Company's Chairman or by the Company's Board of
Directors ("Board") from time to time.

                  Employee may volunteer his service to charitable, business and
other public service agencies, clubs or organizations; provided, however, that
Employee's activities under this clause shall not involve substantial amounts of
Employee's time and shall in no way interfere or detract from the performance of

                  D. Vacation. Employee shall be entitled to three (3) weeks

of the following activities:

                           [1] Directly or indirectly enter into the employ of
         or render any service to or act in concert with any person,
         partnership, corporation or other entity that competes directly or
         indirectly with Company or any business or activity in which Company or
         any successor to Company or CATV shall then be engaged;

                           [2] Directly or indirectly engage in any such
         competitive business or render any such service on his own account; or

                           [3] Become interested in any such competitive
         business or service directly or indirectly as an individual, partner,
         shareholder, director, officer, principal, agent, employee, consultant,
         creditor or in any other relationship or capacity; provided, that the
         purchase of a publicly traded security of a corporation engaged in such
         business or service shall not in itself be deemed violative of this
         Agreement so long as Employee does not own, directly or indirectly,
         more than 3% of the securities of such corporation.

                  B. Non-Solicitation. Employee agrees that for the period he is
employed by the Company and for a two-year period immediately following the
termination of his employment with the Company for any reason whatsoever, he
shall not (other than in the regular course of the Company's business) solicit,
directly or indirectly, business of the type then being performed by the Company
from any person, partnership, corporation or other entity which is a customer of
the Company at the time Employee's employment with the Company terminates, or
was such a customer within the one-year period immediately prior thereto, or to
the knowledge of Employee at the date of termination of employment, is a person,
partnership, corporation or other entity with which the Company plans to do a
substantial amount of business within the one-year period after such termination
of employment.

                  C.       Affiliates. For purposes of this Section 6, 
"Company" as used herein shall mean and include the Company and any affiliate 
of the Company, including without limitation CATV.

         7.       Non-Inducement and Non-Disclosure.

                  A.       Non-Inducement.  Employee agrees that for the 
period he is employed by the Company and for a two-year period immediately 
following the termination of his

                                        3

<PAGE>   4




employment with the Company for any reason whatsoever, he shall not directly or
indirectly, individually or on behalf of persons not parties to this Agreement,
aid or endeavor to solicit or induce any of the Company's employees to leave
their employment with the Company in order to accept employment with Employee or
another person, partnership, corporation or other entity.

                  B. Non-Disclosure. At no time shall Employee divulge, furnish
or make accessible to anyone (other than in the regular course of the Company's
business) any knowledge or information with respect to confidential information
or data of the Company, or with respect to any confidential information or data
of any of the customers of the Company, or with respect to any other
confidential aspect of the business or products or services of the Company or
its customers.

                  C.       Affiliates. For purposes of this Section 7, 
"Company" as used herein shall mean and include the Company and any affiliate 
of the Company, including without limitation CATV.

         8. Injunctive Relief for Breach: Enforceability. Employee agrees that
Company may not be adequately compensated by damages for a breach by Employee of
any of the covenants contained in Sections 6 and 7, and that, in addition to all
other remedies, the Company shall be entitled to injunctive relief and specific
performance. In such event, the periods of time referred to in Sections 6 and 7
shall be deemed extended for a period equal to the respective period during
which Employee is in breach thereof, in order to provide for injunctive relief
and specific performance for a period equal to the full term thereof. The
covenants contained in Sections 6 and 7 shall be construed as separate
covenants, and if any court shall finally determine that the restraints provided
for in any such covenants are too broad as to the geographic area, activity or
time covered, said area, activity or time covered may be reduced to whatever
extent the court deems reasonable and such covenants shall be enforced as to
such reduced area, activity or time.

                  Employee shall indemnify and hold Company harmless from any
liability, loss, damage, judgment, cost or expense (including reasonable
attorneys' fees and expenses) arising out of or resulting from Employee's breach
of any covenants contained in this Agreement or his failure to perform a duty
hereunder.

         9. No Other Non-Compete Agreements. Notwithstanding anything to the
contrary contained herein, Employee hereby represents, warrants and covenants to
Company that Employee (i) is not a party to nor bound by any non-competition,
non-solicitation, confidentiality or other agreement of any kind, which would
conflict with or prevent his employment hereunder or the full performance of all
of his duties hereunder, and (ii) has not, and will not, wrongfully use any
confidential information or know-how taken from another employer. Employee
hereby agrees to indemnify and hold the Company harmless from any claim, loss,
damage and expense hereafter incurred by the Company as

                                        4

a result of any breach of the foregoing representations, warranties or covenants
made by Employee in this Section.

         10. Representations of Employee. The Employee hereby represents,
warrants and agrees with the Company, that the execution, delivery and
performance of this Agreement by the Employee (i) will not constitute a default
under or conflict with any agreement or instrument to which the Employee is a
party or by which he or his assets are bound, (ii) will not conflict with or
violate any order, judgment, decree, statute, ordinance or regulation applicable
to the Employee, and (iii) do not require the consent of any person or entity.

         purchase of a publicly traded security of a corporation engaged in such
         business or service shall not in itself be deemed violative of this
         Agreement so long as Employee does not own, directly or indirectly,
         more than 3% of the securities of such corporation.

                  6.2 Non-Solicitation. Employee agrees that for the period he

accept employment with Employee or another person, partnership, corporation or
other entity.

Company may not be adequately compensated by damages for a breach by Employee of
any of the covenants contained in Sections 6 and 7, and that, in addition to all
other remedies, the Company shall be entitled to injunctive relief and specific
performance. In such event, the periods of time referred to in Sections 6 and 7
shall be deemed extended for a period equal to the respective period during
which Employee is in breach thereof, in order to provide for injunctive relief
and specific performance for a period equal to the full term thereof. The
covenants contained in Sections 6 and 7 shall be construed as separate
covenants, and if any court shall finally determine that the restraints provided
for in any such covenants are too broad as to the geographic area, activity or
time covered, said area, activity or time covered may be reduced to whatever
extent the court deems reasonable and such covenants shall be enforced as to
such reduced area, activity or time.

                  Employee shall indemnify and hold Company harmless from any
liability, loss, damage, judgment, cost or expense (including reasonable
attorneys' fees and expenses) arising out of or resulting from Employee's breach
of any covenants contained in this Agreement or his failure to perform a duty
hereunder.

         9 No Other Non-Compete Agreements. Notwithstanding anything to the
contrary contained herein, Employee hereby represents, warrants and covenants to
Company that Employee (i) is not a party to nor bound by any non-competition,
non-solicitation, confidentiality or other agreement of any kind, which would
conflict with or prevent his employment hereunder or the full performance of all
of his duties hereunder, and (ii) has not, and will not, wrongfully use any
confidential information or know-how taken from another employer. Employee
hereby agrees to indemnify and hold the Company harmless from any claim, loss,
damage and expense hereafter incurred by the Company as a result of any breach
of the foregoing representations, warranties or covenants made by Employee in
this Section.

         10 Representations of Employee. The Employee hereby represents,
warrants and agrees with the Company, that the execution, delivery and
performance of this Agreement by the Employee (i) will not constitute a default

violate any order, judgment, decree, statute, ordinance or regulation applicable
to the Employee, and (iii) do not require the consent of any person or entity.

                                 PROMISSORY NOTE

$650,000.00                                                Louisville, Kentucky
                                                                  April 3, 1998

         FOR VALUE RECEIVED, the undersigned, HIGH SPEED ACCESS NETWORK, INC., a
Delaware corporation ("Borrower"), having an address of 3800 Lark Bunting Lane,
Littleton, Colorado 80127, hereby promises and agrees to pay to GANS MULTIMEDIA
PARTNERSHIP, a Pennsylvania general partnership ("Lender") having an address of
217 East 9th Street, Hazelton, Pennsylvania 18201, the aggregate principal sum
of SIX HUNDRED FIFTY THOUSAND DOLLARS ($650,000.00), together with interest
thereon as hereinafter provided, in lawful money of the United States of
America, in the manner set forth herein, on or before April 2, 2001 (the
"Maturity Date").

         Principal of this Note together with any and all accrued and unpaid
interest and all other sums due and owing under this Note shall be due and
payable as follows: One Hundred Fifty Thousand Dollars ($150,000) of the
principal of this Note shall be due and payable on December 31, 1998; the
remaining principal balance of this Note and all accrued interest thereon shall
be due and payable on the Maturity Date.

         The unpaid principal balance of this Note will accrue interest at a
rate per annum equal to 7%. All interest on this Note shall be computed daily on
the basis of the actual number of days elapsed over a year assumed to consist of
three hundred sixty (360) days. All accrued and unpaid interest on the principal
of this Note shall be payable on the Maturity Date.

         Principal of this Note may be repaid in whole or in part without
penalty or premium at any time prior to maturity; provided, however, that
Borrower shall not be entitled to reborrow any amounts so prepaid. All
prepayments shall be applied to the indebtedness owing hereunder in such order
and manner as Lender may from time to time determine in its sole discretion.

         All payments of principal and interest and any other sums due under
this Note shall be made in immediately available funds to Lender at the address
first set forth above for the Lender in this Note or to such other person or at
such other address as may be designated in writing by the holder of this Note.
Unless otherwise agreed to, in writing, or otherwise required by applicable law,
payments will be applied among principal, interest, late charges, collection
costs and other charges at the discretion of Borrower.

         To secure the indebtedness and undertakings and other obligations of
the Borrower evidenced by or established pursuant to this Note, Borrower, under
the terms of an Assignment and Security Agreement dated of even date herewith
("Security Agreement"), hereby pledges, assigns, transfers, and grants to Lender
a continuing security interest in all property described in Exhibit A attached
to and made a part hereof together with all instruments, documents, securities,
cash, property, and the proceeds of any of the foregoing, owned by Borrower or
in which Borrower has an interest.

         The occurrence of any one or more of the following shall constitute a
default under this Note: (a) if principal or interest under this Note is not
paid as and when due, or within ten (10) days thereafter; (b) the failure to pay
or perform any obligations, liabilities or indebtedness of Borrower to Lender;
(c) the Borrower shall (i) voluntarily commence any proceeding or file any
petition seeking relief under Title 11 of the United States Code or any other
federal, state or foreign


<PAGE>   2




bankruptcy, insolvency, receivership, liquidation or similar law, (ii) consent
to the institution of, or fail to contravene in a timely and appropriate manner,
in any such proceeding or the filing of any such petition, (iii) apply for or
consent to the appointment of a receiver, trustee, custodian, sequestrator or
similar official for a substantial part of its assets, (iv) file an answer
admitting the material allegations of a petition filed against it in any such
proceeding, (v) make a general assignment for the benefit of creditors, (vi)
become unable, admit in writing its inability or fail generally to pay its debts
as they become due or (vii) take any action for the purpose of effecting any of
the foregoing; or (d) an involuntary proceeding shall be commenced or an
involuntary petition shall be filed in a court of competent jurisdiction seeking
(i) relief in respect of the Borrower, or of a substantial part of the property
or assets of the Borrower, under Title 11 of the United States Code or any other
federal, state, or foreign bankruptcy, insolvency, receivership, liquidation or
similar law or (ii) the appointment of a receiver, trustee, custodian,
sequestrator or similar official of the Maker or of a substantial part of the
property or assets of the Borrower; and any such proceeding or petition shall
continue undismissed for sixty (60) consecutive days or an order or decree
approving or ordering any of the foregoing shall continue unstayed and in effect
for sixty (60) consecutive days. Whenever there is a default under this Note the
entire principal balance of and all accrued interest on this Note shall, at the
option of Lender, become forthwith due and payable, without presentment, notice,
protest or demand of any kind (all of which are expressly waived by Borrower).

         Failure of the holder of this Note to exercise any of its rights and
remedies shall not constitute a waiver of the right to exercise the same at that
or any other time. All rights and remedies of the holder for default under this
Note shall be cumulative to the greatest extent permitted by law. Time shall be
of the essence in the payment of all interest and principal on this Note and the
performance of Borrower's other obligations under this Note.

         If there is any default under this Note, and this Note is placed in the
hands of an attorney for collection or is collected through any court, including
any bankruptcy court, Borrower promises to pay to the holder hereof its
reasonable attorneys' fees and court costs incurred in collecting or attempting
to collect or securing or attempting to secure this Note or enforcing the
holder's rights in any collateral securing this Note, provided the same is
legally allowed by the laws of the State of Kentucky.

         If any provision, or portion thereof, of this Note, or the application
thereof to any persons or circumstances shall to any extent be invalid or
unenforceable, the remainder of this Note, or the application of such provision,
or portion thereof, to any other person or circumstances shall not be affected
thereby, and each provision of this Note shall be valid and enforceable to the
fullest extent permitted by law.

         This Note, including matters of construction, validity and performance,
and the obligations arising hereunder, shall be construed in accordance with and
otherwise governed in all respects by the laws of the State of Kentucky
applicable to contracts made and performed in such state and any applicable law
of the United States of America.

         Borrower and any other party who may become primarily or secondarily
liable for any of the obligations of Borrower hereunder hereby jointly and
severally waive presentment, demand, notice of dishonor, protest, notice of
protest, and diligence in collection, and further waive all exemptions to which
they may now or hereafter be entitled under the laws of this or any other state
or of the

                                       2
<PAGE>   3




United States, and further agree that the holder of this Note shall have the
right without notice, to deal in any way, at any time, with Borrower, or any
guarantor of this Note or with any other party who may become primarily or
secondarily liable for, or pledge any collateral as security for, any of the
obligations of Borrower under this Note and to grant any extension of time for
payment of this Note or any other indulgence or forbearance whatsoever, and may
release any security for the payment of this Note and/or modify the terms of the
Security Agreement and any other document securing or pertaining to this Note,
without in any way affecting the liability of Borrower, or such other party who
may pledge any collateral as security for, or become primarily or secondarily
liable for, the obligations of Borrower hereunder and without waiving any rights
the holder may have hereunder or by virtue of the laws of this state or any
other state of the Unites States.

         Until October __, 1999, upon any liquidation, dissolution or winding up
of Borrower, the obligations under this Note, but not Lender's rights under the
Security Agreement, shall be subordinate to the obligations of Borrower to the
holders of Preferred Shares of Borrower as authorized by Borrower's Amended and
Restated Articles of Incorporation on the date hereof. Any merger or
consolidation of Borrower with or into any other corporation or entity or sale
of all or substantially all the assets of Borrower shall be deemed to be a
liquidation, dissolution or winding up of Borrower, except for a merger or
consolidation or sale of all or substantially all the assets of Borrower in
which the shareholders of Borrower immediately prior thereto shall, immediately
thereafter, hold as a group the right to cast at least a majority of the votes
of all holders of voting securities of the resulting or surviving corporation or
entity on any matter on which any such holders of voting securities shall be
entitled to vote. On and after October __, 1999, the obligations under this Note
shall rank pari passu with the obligations of Borrower to the holders of
Preferred Shares of Borrower as authorized by Borrower's Amended and Restated
Articles of Incorporation on the date hereof.

         This Note evidences all indebtedness and obligations of Borrower to
Lender. This Note constitutes the entire agreement between Borrower and Lender
with respect to the subject matter hereof and supersedes any and all other
instruments or other documents evidencing the indebtedness which is the subject
matter hereof, however evidenced.

         WITNESS the signature of the Borrower as of the ____ day of
___________, 1998.

                             1998 STOCK OPTION PLAN



         1.       PURPOSE. The purpose of this Plan is to strengthen the Company
by providing an additional means of retaining and attracting competent
management personnel and by providing to participating officers and other key
employees of the Company added incentive for high levels of performance and for
unusual efforts to increase the earnings of the Company through the opportunity
for stock ownership offered by the Plan.


         2.       DEFINITIONS.  For purposes of this Plan, capitalized words 
and phrases shall have the following meanings:

                  A. Board.  The word "Board" means the Company's Board of 
Directors.

                  B. Change in Control. A "Change in Control" occurs [i] if the
Company or any significant subsidiary of the Company merges or consolidates with
any entity and Broadband Solutions, LLC, or any affiliate thereof, does not own
equity securities of the surviving entity following such merger or
consolidation, or [ii] if all of the Company's outstanding capital stock is
acquired by a person, corporation or other entity which is not a shareholder of
the Company or an affiliate of the Company or any shareholder of the Company, or
[iii] upon the closing of the sale of the Company's Common Stock in a firm
commitment underwritten public offering registered under the Securities Act of
1933, as amended. A significant subsidiary of the Company shall mean any
subsidiary of the Company which, as of the last day of the fiscal year
immediately preceding such Change in Control, constituted fifty percent (50%) or

         5.       GRANT OF OPTIONS.

                  A. Compensation Committee's Authority. Subject to the terms,
provisions and conditions of the Plan, the Compensation Committee shall have
exclusive jurisdiction: [i] to select the employees to whom Options shall be
granted; [ii] to authorize the granting of ISOs, NSOs or a combination of ISOs
and NSOs to employees; [iii] to determine the number of shares of Common

                                       3
<PAGE>   4




Stock subject to each Option; [iv] to determine the time or times when Options
will be granted, the manner in which each Option shall be exercisable, and the
duration of the exercise period; [v] to fix such other provisions of the Option
Agreement as it may deem necessary or desirable consistent with the terms of the
Plan; and [vi] to determine all other questions relating to the administration
of the Plan.

Section 5.A hereof, the maximum aggregate fair market value of Common Stock
(determined as of the date the Option is granted) with respect to which ISOs
will first become exercisable by an Optionee in any calendar year under all ISO
plans of the Company and its Subsidiaries shall not exceed $100,000. Any portion
of an Option granted under the Plan in excess of the foregoing limit shall
constitute a NSO.


         6. ELIGIBILITY. Key employees of the Company and its Subsidiaries,
including officers and directors who are also employees of the Company or a
Subsidiary, are eligible to receive ISOs and NSOs under the Plan. Key employees
of affiliates of the Company who provide services to the Company on a regular
basis ("Affiliate Employees") are eligible to receive NSOs under the Plan;
provided, however, that the aggregate number of shares of Common Stock which may
be issued under the Plan to Affiliate Employees shall not exceed forty five
thousand (45,000) shares. Key employees and Affiliate Employees to whom Options
may be granted under the Plan will be those selected by the Compensation
Committee from time to time who, in the sole discretion of the Compensation
Committee, have contributed in the past or who may be expected to contribute
materially in the future to the successful performance of the Company and its
Subsidiaries.

         7. TERMS OF OPTIONS. Each Option granted under the Plan shall be
evidenced by an Option Agreement signed by the Optionee and by a member of the
Compensation Committee on behalf of the Company. An Option Agreement shall
constitute a binding contract between the Company and the Optionee, and every
Optionee, upon acceptance of such Option Agreement, shall be bound by the terms
and restrictions of the Plan and of the Option Agreement. Such agreement shall
be subject to the following express terms and conditions and to such other terms
and conditions that are not inconsistent with the Plan as the Compensation
Committee may deem appropriate.

                  A. Option Price. The Option Price per share of Common Stock
shall be determined by the Compensation Committee at the time an Option is
granted. The Option Price for ISOs shall be not less than: [i] the fair market
value of Common Stock on the Date of Grant, or [ii] in the case of an ISO
granted to a Ten Percent Shareholder, one hundred ten percent (110%) of the fair
market value of Common Stock on the Date of Grant. The fair market value of
Common Stock shall be determined by:

                  [i] if the Common Stock is traded on the over-the-counter
         market, the closing high bid quotation for the Common Stock in the
         over-the-counter market as reported

                                       4
<PAGE>   5




         by the National Association of Securities Dealers Automated Quotation 
         System, on the business day immediately preceding the Date of Grant;

                  [ii] if the Common Stock is listed on a national securities
         exchange, the aver age of the closing prices of the Common Stock on the
         Composite Tape for the ten (10) consecutive trading days immediately
         preceding such given date; and

                  [iii] if the Common Stock is neither traded on the
         over-the-counter market nor listed on a national securities exchange,
         such value as the Compensation Committee, in good faith, shall
         determine.

                  B. Option Period. Subject to Section 7.C hereof, each Option
Agreement shall specify the period for which the Option thereunder is granted
and shall provide that the Option shall expire at the end of such period. The
Compensation Committee may extend such period provided that, in the case of an
ISO, such extension shall not in any way disqualify the Option as an ISO without
the Optionee's consent. In no case shall such period, including any such
extensions, exceed ten (10) years from the Date of Grant, provided, however,
that in the case of an ISO granted to a Ten Percent Stockholder, such period,
including extensions, shall not exceed five (5) years from the Date of Grant.

                  C.       Lapse of ISO. An ISO shall expire and no longer be 
exercisable at the earliest of the following times:

                           [1]      ten (10) years from the Date of Grant;

                           [2] five (5) years after the Date of Grant, if
         Optionee is a Ten Percent Shareholder on the Date of Grant;

                           [3] three (3) months after termination of employment
         with the Company or a Subsidiary for reasons other than Disability,
         discharge for cause, or death occurring less than three (3) months
         after termination of employment;

                           [4] one (1) year after termination of employment with
         the Company or a Subsidiary because of Optionee's Disability;

                           [5] one (1) year after the date of death if an
         Optionee dies [i] while employed by the Company or a Subsidiary, or
         [ii] within three (3) months after ceasing to be an employee of the
         Company or a Subsidiary; or

                           [6] immediately upon termination of employment
         through discharge for cause, as determined by the Compensation
         Committee in its sole discretion.


                                       5

                  D. Exercise Period. Except to the extent provided otherwise by
Section 7.H hereof, and except as provided in Stock Option Agreements entered
into as of February 20, 1998 by the Company and each of Ron Daggett, Tim Emig
and David Wigglesworth, each stock Option granted under Section 5 hereof shall
be exercisable in the following cumulative installments:

         First installment.  Up to twenty percent (20%) of the total Optioned 
         shares may be exercised at any time after one (1) year following the 
         Date of Grant;

         Second installment.  Up to an additional twenty percent (20%) of the 
         total Optioned shares may be exercised at any time after two (2) years
         following the Date of Grant;

         Third installment. Up to an additional twenty percent (20%) of the
         total Optioned shares may be exercised at any time after three (3)
         years following the Date of Grant;

         Fourth installment. Up to an additional twenty percent (20%) of the
         total Optioned shares may be exercised at any time after four (4) years
         following the Date of Grant; and

         Fifth installment. Up to an additional twenty percent (20%) of the
         total Optioned shares may be exercised at any time after five (5) years
         following the Date of Grant; provided, however, that if Optionee is a
         Ten Percent Shareholder the fifth installment may be exercised at any
         time after fifty-nine (59) months following the Date of Grant.

         If an installment covers a fractional share, such installment shall be
rounded off to the next highest share, except for the final installment, which
will be for the balance of the total Optioned shares.

                  E. Leaves of Absence. The Compensation Committee may, in its
discretion, treat all or any portion of any period during which an Optionee is
on military or on an approved leave of absence from the Company or a Subsidiary
as a period of employment of the Optionee by the Company or Subsidiary for
purposes of accrual of the Optionee's rights under the Plan. Notwith standing
the foregoing, if a leave of absence exceeds ninety (90) days and reemployment
is not guaranteed by contract or statute, the Optionee's employment by the
Company or a Subsidiary for the purposes of the Plan shall be deemed to have
terminated on the 91st day of the leave.

                  F. Manner of Exercise. To exercise an Option, the Optionee
shall deliver to the Company: [i] seven (7) days' prior written notice
specifying the number of shares as to which the Option is being exercised and,
if determined by counsel for the Company to be necessary, repre senting that
such shares are being acquired for investment purposes only and not for purpose
of resale or distribution; and [ii] payment by the Optionee, or a broker-dealer
(as provided in Section 7.G hereof), for such shares of the Option Price for the
number of shares with respect to which the Option is exercised. On or before the
expiration of the seven (7) day notice period, and provided that all conditions
precedent contained in the Plan are satisfied, the Company shall, without
transfer or

                                       6
<PAGE>   7




issuance tax or other incidental expenses to Optionee, deliver to Optionee, at
the offices of the Company, or at such other place as may be mutually
acceptable, or, at the election of the Company, by certified mail addressed to
Optionee at Optionee's address as shown in the records of the Company, a
certificate or certificates for the Common Stock. Options are exercisable only
in whole shares, and fractional share interests shall be treated in the manner
described in Section 7.D. If Optionee fails to accept delivery of the Common
Stock, the Optionee's rights to exercise the applica ble portion of the Option
shall terminate.

                  G. Payment for Shares. Except as otherwise provided in this
Section 7, the Option Price for the Common Stock shall be paid in full when the
Option is exercised. Subject to such rules as the Committee may impose and the
terms of the Option Agreement, the Option Price may be paid in whole or in part
in [i] cash, [ii] certified or cashier's check, [iii] whole shares of Common
Stock owned by the Optionee evidenced by negotiable certificates, [iv] such
other consideration as shall constitute lawful consideration for the issuance of
Common Stock and be approved by the Committee (including without limitation,
assurance satisfactory to the Committee from a broker registered under the
Exchange Act of the delivery of the proceeds of an imminent sale of the Common
Stock to be issued pursuant to the exercise of such Option, such sale to be made
at the direction of the Optionee), or [v] by a combination of such methods of
payment. If payment of the Option Price is made in Common Stock, the value of
the Common Stock used for payment of the Option Price shall be the fair market
value of the Common Stock, determined in accordance with Section 7.A hereof, on
the business day preceding the day written notice of exercise is delivered to
the Company.

                  H. Acceleration. Notwithstanding the provisions of Sections
7.B or D hereof to the contrary, if there is a Change in Control, the exercise
dates of all outstanding Options shall accelerate so that each Option
outstanding may be exercised on or after the date of the Change in Control.

                  I. ISOs. Each Option Agreement which provides for the grant of
an ISO shall contain such terms and provisions as the Compensation Committee
deems necessary or desirable to qualify such Option as an ISO within the meaning
of Code Section 422.

                  J. Transferability of Options. During Optionee's lifetime, the
Option shall be exercisable only by Optionee, and neither the Option nor any
right hereunder shall be transferable except by will or by the laws of descent
and distribution. The Option may not be subject to execution or other similar
process. If Optionee attempts to alienate, assign, pledge, hypothecate or
otherwise dispose of the Option or any of Optionee's rights hereunder, except as
provided herein, or in the event of any levy, attachment, execution or similar
process upon the rights or interests hereby conferred, the Company may, in its
sole and absolute discretion, terminate the Option by notice to Optionee and it
shall thereupon become null and void.

         8. ADJUSTMENT OF SHARES. In the event of capital adjustment after the
effective date of the Plan in the Common Stock of the Company by reason of any
reorganization, recapital ization, stock split, stock dividend, combination or
exchange of shares, merger or consolidation, or any other change (after the
effective date of the Plan) in the nature or number of shares of Common Stock of
the Company, a proportionate adjustment shall be made in the maximum number and
kind of shares which may be delivered under the Plan, and in the Option Price
under and the number and kind of shares of Common Stock covered by outstanding
Options granted under the Plan. By virtue of such a capital adjustment, the
price of any share under Option shall be adjusted so that there will be no
change in the aggregate purchase price payable upon exercise of any such Option.
Such determination by the Compensation Committee shall be conclusive.

                  Without limiting the generality of the foregoing, if [a] there
is a Change in Control of the Company, and [b] as a result of the transactions
contemplated by the Change in Control, a Successor will acquire all or
substantially all of the assets or 50% of more of the Company's outstanding
voting stock, then the kind of shares of common stock which shall be subject to
the Plan and to each outstanding Option shall automatically be converted into
and replaced by shares of common stock, or such other class of equity securities
having rights and preferences no less favorable than common stock of the
Successor, and the number of shares subject to the Options and the purchase
price per share upon exercise of the Options shall be correspondingly adjusted,
so that, by virtue of such Change in Control of the Company, each Optionee shall
have the right to purchase [i] that number of shares of the Successor which, as
of the date of the Change in Control, have a fair market value equal to the fair
market value of the shares of the Company theretofore subject to an Option, [ii]
for a purchase price per share which, when multiplied by the number of shares of
the Successor subject to the Option, shall equal the aggregate exercise price at
which the Optionee could have acquired shares of the Company under such Option.

                  The granting of an Option pursuant to this Plan shall not
affect in any way the right and power of the Company to make adjustments,
reorganizations, reclassifications, or changes of its capital or business
structure or to merge, consolidate, dissolve, liquidate, sell or transfer all or
any part of its business or assets; provided, however, that the Company shall
not, and shall not permit its Subsidiaries to, recommend or agree or consent to
a transaction or series of transactions which would result in a Change of
Control of the Company unless and until the person or persons acquiring or
succeeding to assets or capital stock of the Company or its Subsidiaries as a
result of such transaction or transactions agrees to be bound by the terms of
the Plan so far as it pertains to Options therefore granted and agrees to assume
and perform the obligations of the Company and its Successor under the Plan.


         9.       COMPLIANCE WITH OTHER LAWS AND REGULATIONS.  Upon the
exercise of an Option at a time when there is not in effect a registration
statement under the Securities Act of 1933, as amended, and any applicable state
securities laws (the "Securities Laws") relating to the shares of Common Stock
issuable upon exercise thereof and available for delivery a prospectus meeting
the requirements of the Securities Laws, the shares of Common Stock may be
issued only if the Optionee or Optionee Representative represents and warrants
in writing to the

                                       8
<PAGE>   9




Company that the shares being purchased are being acquired for investment and
not with a view to the distribution thereof. The shares of the Common Stock
shall contain such legends or other re strictive endorsements as counsel for the
Company shall deem necessary or proper. No shares of Common Stock shall be
purchased upon the exercise of any Option unless and until there shall have been
satisfied any applicable requirements of the Securities and Exchange Commission
or other regulatory agencies having jurisdiction and of any exchanges upon which
stock of the Company may be listed.

         10. STOCK RESTRICTION AGREEMENT. Upon the exercise of any Option and
the issuance of Common Stock to an Optionee, Optionee shall execute a Stock
Restriction and Buy Sell Agreement providing for a right of first refusal to the
Company prior to the sale of any Common Stock by an Optionee and an option to
the Company to repurchase at fair market value any shares of Common Stock issued
under the Plan upon the death, disability or termination of employment of an
Optionee.


         11. NO RIGHTS AS SHAREHOLDER. No Optionee or Optionee's Representative
shall have any rights as a shareholder with respect to Common Stock subject to
Optionee's Option before the date of transfer to the Optionee of a certificate
or certificates for such shares.


         12.      NO RIGHTS TO CONTINUED EMPLOYMENT.  The Plan and any Option
granted under the Plan shall not confer upon any Optionee any right with respect
to continuance of employment by the Company or any Subsidiary, nor shall it
interfere in any way with the right of the Company or any Subsidiary by which an
Optionee is employed to terminate Optionee's employment at any time.


         13. TERMINATION. The Plan shall terminate on March 31, 2008, ten (10)
years from the earlier of the date it was adopted by the Board or approved by
the shareholders of the Company, and may be terminated at any earlier time by
the Compensation Committee. No Option shall be granted after termination of the
Plan. Termination of the Plan, however, shall not affect the validity of any
Option theretofore granted under the Plan.


         14. AMENDMENT. The Board shall have the right, at any time, to amend,
suspend or terminate the Plan in any respect that it may deem to be in the best
interests of the Company, except that, without approval by shareholders of the
Company holding not less than a majority of the votes represented and entitled
to be voted at a duly held meeting of the Company's shareholders, no amendment
shall be made if shareholder approval is necessary to qualify the Plan under the
Securities and Exchange Commission Rule 16b-3. No amendment of the Plan,
however, may, without the consent of the Optionee or Optionee Representative,
make any changes in any

                                       9
<PAGE>   10




outstanding Option theretofore granted under the Plan which would adversely
affect the rights of such Optionee or Optionee Representative.


         15. TAX WITHHOLDING. Upon the exercise of any Option granted under the
Plan, or upon the disposition of any Common Stock acquired by the exercise of an
ISO granted under the Plan within two (2) years from the Date of Grant or one
(1) year after such Common Stock is trans ferred to the Optionee, the Company
shall have the right to require Optionee to remit to the Company an amount
sufficient to satisfy all federal, state and local withholding tax requirements,
or, alternatively, the Company shall have the right to retain Common Stock
otherwise payable to the Optionee pursuant to exercise of an Option in an amount
sufficient to satisfy such withholding requirements, before the delivery to the
Optionee of any certificate(s) for shares of Common Stock.


         16. GOVERNING LAW. This Plan and the Option Agreements entered into
under the Plan shall be governed by, and construed in accordance with, the laws
of Kentucky.


         17. EFFECTIVE DATE. The effective date of the Plan shall be
April 3, 1998. The Plan was adopted by the Board on April 3, 1998, and approved
by stockholders of the Company holding not less than a majority of the shares
represented and entitled to vote on April 3, 1998.

                  THIS INDEMNITY AGREEMENT dated as of March__, 1999 (the
"Agreement"), is entered into by and between High Speed Access Corp., a Delaware
corporation (the "Company"), and _____________________ ("Indemnitee").


                                 R E C I T A L S

                  A. The Company is aware that competent and experienced persons
are increasingly reluctant to serve as directors of corporations unless they are
protected by comprehensive liability insurance or indemnification, due to
increased exposure to litigation costs and risks resulting from their service to
such corporations, and due to the fact that the exposure frequently bears no
reasonable relationship to the compensation of such directors.

                  B. The statutes and judicial decisions regarding the duties of
directors are often difficult to apply, ambiguous, or conflicting, and therefore
fail to provide such directors with adequate, reliable knowledge of legal risks
to which they are exposed or information regarding the proper course of action
to take.

                  C. Plaintiffs often seek damages in such large amounts and the
costs of litigation may be so enormous (whether or not the case is meritorious),
that the defense and/or settlement of such litigation is often beyond the
personal resources of directors.

                  D. The Company believes that it is unfair for its directors to
assume the risk of huge judgments and other expenses which may occur in cases in
which the director received no personal profit and in cases where the director
was not culpable.

                  E. The Company recognizes that the issues in controversy in
litigation against a director of a corporation such as the Company are often
related to the knowledge, motives and intent of such director, that he is
usually the only witness with knowledge of the essential facts and exculpating
circumstances regarding such matters, and that the long period of time which
usually elapses before the trial or other disposition of such litigation often
extends beyond the time that the director can reasonably recall such matters;
and may extend beyond the normal time for retirement for such director with the
result that he, after retirement or in the event of his death, his spouse,
heirs, executors or administrators, may be faced with limited ability and undue
hardship in maintaining an adequate defense, which may discourage such a
director from serving in that position.

                  F. Based upon their experience as business managers, the Board
of Directors of the Company (the "Board") has concluded that, to retain and
attract talented and experienced individuals to serve as directors of the
Company and to encourage such individuals to take the business risks necessary
for the success of the Company, it is necessary for the Company to contractually
indemnify its directors, and to assume for itself maximum liability for expenses
and damages in connection with claims against such directors in connection with
their service to the Company, and has further concluded that the failure to
provide such contractual indemnification could result in great harm to the
Company and the Company's stockholders.

                  G. Section 145 of the General Corporation Law of Delaware,
under which the Company is organized ("Section 145"), empowers the Company to
indemnify its directors, officers, employees and agents by agreement and to
indemnify persons who serve, at the request of the Company, as the directors,
officers, employees or agents of other corporations or enterprises, and
expressly provides that the indemnification provided by Section 145 is not
exclusive.

                  H. The Company desires and has requested the Indemnitee to
serve or continue to serve as a director of the Company free from undue concern
for claims for damages arising out of or related to such services to the
Company.

                  I. Indemnitee is willing to serve, or to continue to serve,
the Company, provided that he is furnished the indemnity provided for herein.

                                A G R E E M E N T

                  NOW, THEREFORE, the parties hereto, intending to be legally
bound, hereby agree as follows:

         1.       Definitions.


                                       2
<PAGE>   3



                  A. Expenses. For purposes of this Agreement, "expenses"
include all out-of-pocket costs of any type or nature whatsoever (including,
without limitation, all attorneys' fees and related disbursements), actually and
reasonably incurred by the Indemnitee in connection with either the
investigation, defense or appeal of a proceeding or establishing or enforcing a
right to indemnification under this Agreement or Section 145 or otherwise;
provided, however, that "expenses" shall not include any judgments, fines, ERISA
excise taxes or penalties, or amounts paid in settlement of a proceeding.

                  B. Proceeding. For the purposes of this Agreement,
"proceeding" means any threatened, pending, or completed action, suit or other
proceeding, whether civil, criminal, administrative, or investigative.

         2. Agreement to Serve. The Indemnitee agrees to serve and/or continue
to serve as director of the Company, at its will (or under separate agreement,
if such agreement exists), so long as he is duly appointed or elected and
qualified in accordance with the applicable provisions of the Bylaws of the
Company or until such time as he tenders his resignation in writing.

         3.       Liability Insurance.

                  A. Maintenance of D&O Insurance. At such time as the Board
deems it appropriate to obtain such insurance but not before such time, the
Company hereby covenants and agrees that, so long as the Indemnitee shall
continue to serve as director of the Company and thereafter so long as the
Indemnitee shall be subject to any possible proceeding by reason of the fact
that the Indemnitee was director of the Company, the Company, subject to Section
3.C, shall promptly obtain and maintain in full force and effect directors' and
officers' liability insurance ("D&O Insurance") in reasonable amounts from
established and reputable insurers.

                  B. Rights and Benefits. In all policies of D&O Insurance, the
Indemnitee shall be named as an insured in such a manner as to provide the
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's directors.


                                       3
<PAGE>   4



                  C. Limitation on Required Maintenance of D&O Insurance.
Notwithstanding the foregoing, the Company shall have no obligation to obtain or
maintain D&O Insurance if the Company determines in good faith that such
insurance is not reasonably available, the premium costs for such insurance are
disproportionate to the amount of coverage provided, the coverage provided by
such insurance is limited by exclusions so as to provide an insufficient
benefit, or the Indemnitee is covered by similar insurance maintained by a
subsidiary of the Company.

         4. Mandatory Indemnification. Subject to Section 8 below, the Company
shall indemnify the Indemnitee as follows:

                  A. Successful Defense. To the extent the Indemnitee has been
successful on the merits or otherwise in defense of any proceeding (including,
without limitation, an action by or in the right of the Company) to which the
Indemnitee was a party by reason of the fact that he is or was a director of the
Company at any time, against all expenses of any type whatsoever actually and
reasonably incurred by him in connection with the investigation, defense or
appeal of such proceeding.

                  B. Third Party Actions. If the Indemnitee is a person who was
or is a party or is threatened to be made a party to any proceeding (other than
an action by or in the right of the Company) by reason of the fact that he is or
was a director of the Company, or by reason of anything done or not done by him
in any such capacity, the Company shall indemnify the Indemnitee against any and
all expenses and liabilities of any type whatsoever (including, but not limited
to, judgments, fines, ERISA excise taxes and penalties, and amounts paid in
settlement) actually and reasonably incurred by him in connection with the
investigation, defense, settlement or appeal of such proceeding, provided the
Indemnitee 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 its stockholders, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful.

                  C. Derivative Actions. If the Indemnitee is a person who was
or is a party or is threatened to be made a party to any proceeding by or in the
right of the Company by reason of the fact that he is or was a director of the
Company, or by reason of anything done or not done by him in any such capacity,
the Company shall indemnify the Indemnitee against all expenses actually and
reasonably incurred by him in connection with the investigation, defense,
settlement, or appeal of such proceeding, provided the Indemnitee 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 its stockholders; except that no indemnification
under this subsection 4.C shall be made in respect to any claim, issue or matter
as to which such person shall have been finally adjudged to be liable to the
Company by a court of competent jurisdiction unless and only to the extent that
the court in which such proceeding was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
amounts which the court shall deem proper.

                  D. Actions where Indemnitee is Deceased. If the Indemnitee is
a person who was or is a party or is threatened to be made a party to any
proceeding by reason of the fact that he is or was a director of the Company, or
by reason of anything done or not done by him in any such capacity, and if prior
to, during the pendency or after completion of such proceeding Indemnitee
becomes deceased, the Company shall indemnify the Indemnitee's heirs, executors
and administrators against any and all expenses and liabilities of any type
whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes
and penalties, and amounts paid in settlement) actually and reasonably incurred
to the extent Indemnitee would have been entitled to indemnification pursuant to
Sections 4.A, 4.B, or 4.C above were Indemnitee still alive.

                  E. Notwithstanding the foregoing, the Company shall not be
obligated to indemnify the Indemnitee for expenses or liabilities of any type
whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes
and penalties, and amounts paid in settlement) for which payment is actually
made to or on behalf of Indemnitee under a valid and collectible insurance
policy of D&O Insurance, or under a valid and enforceable indemnity clause,
by-law or agreement.

         5. Partial Indemnification. If the Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of any expenses or liabilities of any type whatsoever (including, but
not limited to, judgments, fines, ERISA excise taxes and penalties, and amounts
paid in settlement) incurred by him in the investigation, defense, settlement or
appeal of a proceeding, but not entitled, however, to indemnification for all of
the total amount hereof, the Company shall nevertheless indemnify the Indemnitee
for such total amount except as to the portion hereof to which the Indemnitee is
not entitled.

         6. Mandatory Advancement of Expenses. Subject to Section 8.A below, the
Company shall advance all expenses incurred by the Indemnitee in connection with
the investigation, defense, settlement or appeal of any proceeding to which the
Indemnitee is a party or is threatened to be made a party by reason of the fact
that the Indemnitee is or was a director of the Company. Indemnitee hereby
undertakes to repay such amounts advanced only if, and to the extent that, it
shall be determined ultimately that the Indemnitee is not entitled to be
indemnified by the Company as authorized hereby. The advances to be made
hereunder shall be paid by the Company to the Indemnitee within twenty (20) days
following delivery of a written request therefor by the Indemnitee to the
Company.

         7.       Notice and Other Indemnification Procedures.

                  A. Promptly after receipt by the Indemnitee of notice of the
commencement of or the threat of commencement of any proceeding, the Indemnitee
shall, if the Indemnitee believes that indemnification with respect thereto may
be sought from the Company under this Agreement, notify the Company of the
commencement or threat of commencement thereof.

                  B. If, at the time of the receipt of a notice of the
commencement of a proceeding pursuant to Section 7.A hereof, the Company has D&O
Insurance in effect, the Company shall give prompt notice of the commencement of
such proceeding to the insurers in accordance with the procedures set forth in
the respective policies. The Company shall thereafter take all necessary or
desirable action to cause such insurers to pay, on behalf of the Indemnitee, all
amounts payable as a result of such proceeding in accordance with the terms of
such policies.


                                       5
<PAGE>   6



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

         8. Exceptions. Any other provision herein to the contrary
notwithstanding, the Company shal1 not be obligated pursuant to the terms of
this Agreement:

                  A. Claims Initiated by Indemnitee. To indemnify or advance
expenses to the Indemnitee with respect to proceedings or claims initiated or
brought voluntarily by the Indemnitee and not by way of defense, unless (i) such
indemnification is expressly required to be made by law, (ii) the proceeding was
authorized by the Board, (iii) such indemnification is provided by the Company,
in its sole discretion, pursuant to the powers vested in the Company under the
General Corporation Law of Delaware or (iv) the proceeding is brought to
establish or enforce a right to indemnification under this Agreement or any
other statute or law or otherwise as required under Section 145.

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

                  C. Unauthorized Settlements. To indemnify the Indemnitee under
this Agreement for any amounts paid in settlement of a proceeding unless the
Company consents to such settlement, which consent shall not be unreasonably
withheld.

         9. Non-exclusivity. The provisions for indemnification and advancement
of expenses set forth in this Agreement shall not be deemed exclusive of any
other rights which the Indemnitee may have under any provision of law, the
Company's Certificate of Incorporation or Bylaws, the vote of the Company's
stockholders or disinterested directors, other agreements, or otherwise, both as
to action in his official capacity and to action in another capacity while
occupying his position as a director of the Company, and the Indemnitee's rights
hereunder shall continue after the Indemnitee has ceased acting as a director of
the Company and shall inure to the benefit of the heirs, executors and
administrators of the Indemnitee.


                                       6
<PAGE>   7



         10. Enforcement. Any right to indemnification or advances granted by
this Agreement to Indemnitee shall be enforceable by or on behalf of Indemnitee
in any court of competent jurisdiction if (i) the claim for indemnification or
advances is denied, in whole or in part, or (ii) no disposition of such claim is
made within ninety (90) days of request therefor. Indemnitee, in such
enforcement action, if successful in whole or in part, shall be entitled to be
paid also the expense of prosecuting his claim. It shall be a defense to any
action for which a claim for indemnification is made under this Agreement (other
than an action brought to enforce a claim for expenses pursuant to Section 6
hereof, provided that the required undertaking has been tendered to the Company)
that Indemnitee is not entitled to indemnification because of the limitations
set forth in Sections 4 and 8 hereof. Neither the failure of the Company
(including its Board or its stockholders) to have made a determination prior to
the commencement of such enforcement action that indemnification of Indemnitee
is proper in the circumstances, nor an actual determination by the Company
(including its Board or its stockholders) that such indemnification is improper,
shall be a defense to the action or create a presumption that Indemnitee is not
entitled to indemnification under this Agreement or otherwise.

         11. Subrogation. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

         12.      Survival of Rights.

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

                  B. The Company shall require any successor(s) to the Company
(whether direct or indirect, by purchase, merger, consolidation or otherwise) or
to all or substantially all of the business or assets of the Company, expressly
to assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform if no such succession had
taken place.

         13. Interpretation of Agreement. It is understood that the parties
hereto intend this Agreement to be interpreted and enforced so as to provide
indemnification to the Indemnitee to the fullest extent permitted by law
including those circumstances in which indemnification would otherwise be
discretionary.


                                       7
<PAGE>   8



         14. Severability. If any provision or provisions of this Agreement
shall be held to be invalid, illegal or unenforceable for any reason whatsoever,
(i) the validity, legality and enforceability of the remaining provisions of the
Agreement (including without limitation, all portions of any paragraphs of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby, and (ii) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, all
portions of any paragraph of this Agreement containing any such provision held
to be invalid, illegal or unenforceable, that are not themselves invalid,
illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable and to give
effect to Section 13 hereof.

         15. Modification and Waiver. No supplement, modification or amendment
of this Agreement shall be binding unless executed in writing by both of the
parties hereto. No waiver of any of the provisions of this Agreement shall be
deemed or shall constitute a waiver of any other provisions hereof (whether or
not similar) nor shall such waiver constitute a continuing waiver.

         16. Notice. All notices, requests, demands and other communications
under this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and receipted for by the party addressee, on the date of
delivery, or (ii) if mailed by certified or registered mail with postage
prepaid, on the third business day after the mailing date. Addresses for notice
to either party are as shown on the signature page of this Agreement, or as
subsequently modified by written notice.

         17. Governing Law. This Agreement shall be governed exclusively by and
construed according to the laws of the State of Delaware, without giving effect
to conflicts of law principles.


         IN WITNESS WHEREOF, the parties hereto have entered into this Indemnity
Agreement effective as of the date first above written.

                                  THE COMPANY:
