the other to be used in connection with the concurrent offerings to Cisco, Com21
and Microsoft. The public offering prospectus and the concurrent offering
prospectus are identical in all respects except for the front cover pages, the

descriptions of legal matters. The alternate pages of the concurrent offering
prospectus are included herein after the final page of the public offering
prospectus and are labeled "Alternate Page for Concurrent Offering Prospectus."

                               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, which we define as cable
systems with fewer than 100,000 homes passed. We believe that we provide the
most comprehensive turnkey solution available to the cable operator in exurban
markets, whereby the cable operator may outsource the services required to
provide Internet access and other ancillary services. 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, the
ultimate residential or business consumers of our services.



     We target exurban markets, defined as cable systems with fewer than 100,000
homes passed. The term "homes passed" refers to the number of homes that
potentially can be served by a cable system. The exurban 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 20 cable operators, covering 51 systems and approximately 982,000 homes
passed. We also have non-binding letters of intent to provide these services to
another 14 operators representing an additional 23 systems and approximately
303,000 homes passed. We have commenced full operations in 21 systems covering
approximately 319,000 homes passed, where we are marketing our services to end
users. We have initiated operations in another 21 systems covering an additional
402,000 homes, and have approximately 3,900 high speed 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., one of the ten largest cable system
operators in the United States. Charter has agreed to provide us with exclusive
access to at least 750,000 homes passed, and has an equity incentive to provide
us up to an additional 5 million homes passed.

     We recently entered into a non-binding letter of intent with ServiceCo LLC,
the entity that provides Road Runner's cable Internet access and content
aggregation services, and we and ServiceCo are currently in the process of
negotiating a definitive agreement. ServiceCo is a joint venture among
affiliates of Time Warner, Inc., MediaOne Group, Inc., Microsoft Corporation,
Compaq Corp. and Advance/Newhouse. This letter of intent contemplates that we
will provide our services to cable systems designated by ServiceCo and us, and
enter into a revenue sharing arrangement among HSA, ServiceCo and the cable
operator. We also would grant ServiceCo a warrant to purchase one share of
common stock at a price of $5 per share for each home passed that we jointly
designate to receive our services, up to a maximum of 5 million homes. In
addition, ServiceCo would be entitled to provide Road Runner content in these
designated systems.


     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, having transmission speeds with bandwiths greater 128
Kilobits per second. 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, compared
with 56 kilobits per second 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,


                                        1
<PAGE>   8

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 cable systems that are
       either upgraded or non-upgraded for two-way data transmission
       capabilities;


     - Source of additional revenues with minimal associated operating or
       capital cost; and

     - Dedicated onsite local and national end user marketing provided by us.

     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 42 systems we have installed to date, of which 21 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, SPONSORSHIP AND STRATEGIC RELATIONSHIPS

     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. In April 1999, Vulcan purchased 5 million
shares of our Series C convertible preferred stock for $5.00 per share, which
will be converted into 7.75 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. Charter also has warrants to purchase up to an additional 7.75
million shares of our common stock, for $3.23 per share, which become
exercisable at the rate of 1.55 shares 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 Go2Net, Inc., USA Networks, ZDTV,
Beyond.com, N2K, Inc., Northpoint Communications, Inc., Wink Communications,
Value America, Inc. and Priceline.com. Certain of the principals of Broadband
Solutions, which beneficially owns 29.2% of our
                                        2
<PAGE>   9

common stock before the offering, co-founded and invested in Premier Parks Inc.,
Regal Cinemas, Inc. and Regent Communications, Inc. (subsequently sold to Jacor
Communications). The investor group that founded High Speed Access Network, Inc.
includes cable television pioneer Joseph Gans, III.

     Concurrently with this offering, Cisco, and Com21, two of our major
equipment suppliers, have agreed to purchase $7.5 million and $1.0 million,
respectively, of our common stock at the initial public offering price, net of
the underwriting discount. Additionally, Microsoft, a strategic marketing
partner, has agreed to purchase $10 million of our common stock at the initial
public offering price, net of the underwriting discount. We believe that both
our sponsor and strategic relationship groups and their knowledge of, and
extensive connections in, the media, Internet and cable industries help position
us to compete in the high speed cable modem Internet access market.

       Charter in excess of 750,000. See "Certain Transactions."

     - Microsoft has a warrant to purchase 250,000 shares of our common stock at
       an exercise price of 125% of the initial public offering price. This
       warrant will provide Microsoft the right to purchase one additional share
       of our common stock for each additional 10 homes passed above 2.5 million
       homes passed Comcast commits to us by May 1, 2002.

     - A non-binding letter of intent we recently signed with ServiceCo LLC, the
       entity that provides Road Runner's cable Internet access and content
       aggregation services, contemplates that we will grant warrants to
       purchase one share of our common stock at a price of $5 per share for
       each home passed that we jointly designate to receive our services, up to
       a maximum of 5 million shares.

     The following table sets forth our summary financial data. You should read
this information together with the financial statements and the notes to those
statements appearing elsewhere in this prospectus and the information under
"Selected Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."



     The combined pro forma data for the year ended December 31, 1998 gives
effect to our acquisition of CATV.net, Inc. and High Speed Access Network, Inc.
as if those acquisitions had occurred on January 1, 1998.



     The pro forma basic and diluted net loss per share for the historical
periods April 3, 1998 through December 31, 1998 and for the three months ended
March 31, 1999 give effect to the assumed conversion of our Series A and Series
B convertible preferred stock into shares of common stock at the date the shares
of convertible preferred stock were issued. The pro forma basic and diluted net
loss per share for the combined pro forma year ended December 31, 1998 assumes
that (a) our Series A convertible preferred stock had been issued on January 1,
1998 and immediately converted into shares of common stock and (b) that our
Series B convertible preferred stock had been immediately converted into common
stock upon the respective dates of issuance of the Series B convertible
preferred stock. As a result of such assumed conversions, dividends and
accretion of redemption value of the preferred stock are excluded from the net
loss available to common stockholders.

                                  RISK FACTORS

     You should carefully consider the following factors and other information
in this prospectus before deciding to invest in our common stock. 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.

                        RISKS RELATED TO OUR OPERATIONS

OUR BUSINESS IS DIFFICULT TO EVALUATE BECAUSE WE HAVE A LIMITED OPERATING
HISTORY.

     Our predecessor companies began offering services to cable operators in
October 1997. We have recognized limited revenues since our inception. In
addition, our senior management team and other employees have worked together at
our company for only a short period of time. Consequently, we have a limited
operating history upon which you can evaluate our business.

WE HAVE NOT BEEN PROFITABLE 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 net
losses of approximately $18 million from April 3, 1998 (Inception) through March
31, 1999. 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, a very high-capacity, long-distance line that can carry large
       amounts of Internet traffic and data from one regional network to another
       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, software and
       telecommunications circuits 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.

WE CANNOT PREDICT OUR SUCCESS BECAUSE 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 22 cable systems and we have
                                        7
<PAGE>   14

approximately 3,510 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, equipment located in a
       central distribution point in a cable television system, 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 AND MAY BE
BELOW THE EXPECTATIONS OF ANALYSTS AND INVESTORS.

     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 pace of the rollout of our service to our cable partners, including
       the impact of substantial capital expenditures and related operating
       expenses;

     - 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;

     - 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;
                                        8
<PAGE>   15

     - 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 MAY NOT BE ABLE TO ESTABLISH OR MAINTAIN 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 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 is owned by
Vulcan Ventures, which beneficially owns 54.2% of our common stock before the
offering. Charter has committed to provide us exclusive access to at least
750,000 homes passed. Charter has equity incentives to provide us additional
homes passed, although it is not 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 the benchmarks related to our customer penetration rates
or that Charter will not decide to terminate our agreement for any other reason.
If Charter were to terminate this agreement, 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

                                        9
<PAGE>   16

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 in Vulcan's discretion and can require
us to remove competing content. 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.

ANY AGREEMENT THAT WE MAY SIGN WITH ROAD RUNNER MAY NOT BENEFIT US.

     We recently entered into a non-binding letter of intent with ServiceCo LLC,
the entity that provides Road Runner's cable Internet access and content
aggregation services. The letter of intent contemplates that we will provide our
services as a Road Runner subcontractor to cable operators that we and Road
Runner jointly designate to receive our services. We can offer no assurances
that we will be able to reach a definitive agreement with ServiceCo or that, if
reached, a definitive agreement will be of material benefit to us. In addition,
we may not be able to meet the system deployment schedule ultimately proposed by
Road Runner. Moreover, while we expect that only a portion of the homes
contemplated under the letter of intent will be deployed on a partial turnkey
basis, Road Runner could ask us to deploy more partial turnkey homes than we
anticipate. In a partial turnkey solution, we will deliver fewer services and
possibly incur lower costs than in a full turnkey solution, but will also earn a
smaller percentage of the subscription revenue. Since the letter of intent
contemplates that Road Runner will earn one warrant per home passed in cable
systems designated to receive service regardless of whether we deploy a partial
or full turnkey solution, our stockholders could suffer dilution in exchange for
potentially less profitable homes.

INVESTORS MAY SUFFER SUBSTANTIAL DILUTION FROM OTHER TRANSACTIONS.

     As an inducement to cause Charter Communications to commit additional
systems to us, we have granted Charter warrants to purchase up to 7.75 million
shares of our common stock at an exercise price of $3.23 per share. These
warrants become exercisable at the rate of 1.55 shares for each home passed
committed to us by Charter in excess of 750,000. To the extent that Charter
becomes eligible to exercise all or a significant portion of these warrants, our
stockholders will experience substantial dilution. In addition, we have granted
Microsoft a warrant to purchase 250,000 shares of our common stock at an
exercise price of 125% of the initial public offering price, with additional
warrants issuable for homes passed above 2.5 million homes committed to us by
Comcast. Our letter of intent with ServiceCo LLC contemplates our granting of
warrants to purchase one share of our common stock at a price of $5 per share up
to a maximum of 5 million shares. 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.

     In March 1999, we transferred all of the assets used in our digital
subscriber line technology division to Darwin Networks, Inc., a newly-formed
subsidiary, and distributed all of the Darwin common stock to our current
stockholders. 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, if
Darwin were to deploy this technology successfully in future partnerships with
wireline telephone providers in markets where we provide our high speed Internet
access, Darwin could
                                       10
<PAGE>   17

become one of our competitors. Furthermore, although we will have a warrant to
purchase one million shares of Darwin's common stock, representing approximately
a 20% interest in Darwin on a fully-diluted basis immediately after the
spin-off, if Darwin is successful, our current stockholders, and not those
investing in us in this offering, will realize a greater proportion of Darwin's
success. Neither Darwin nor our principal stockholders, Vulcan Ventures and
Broadband Solutions, will be restricted from providing competing high speed
digital subscriber line Internet access. 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 the cable headend via a
standard phone line. Because we must support the telephone return component of
the system, we incur higher operating costs in one-way systems. Presently only
one-third of the systems where we are or will soon operate our services are
two-way systems. Over time, however, we expect most, if not all, of our cable
partners to upgrade and or rebuild their plants to provide increased bandwidth
and two-way capabilities. We believe faster uploads and the elimination of phone
line return costs make our service more valuable and may lead to higher customer
penetration rates, which in turn benefits the cable operator through higher
revenue. However, upgrading a cable system can be expensive and time-consuming
for the cable operator. Moreover, we do not require our cable partners to make
these upgrades and they have no legal obligation to do so. Consequently, if our
cable partners do not upgrade to two-way capability at the rate we anticipate,
our financial results may be negatively affected.


IF WE ARE UNABLE TO EFFECTIVELY MANAGE OUR GROWTH, WE MAY EXPERIENCE OPERATING
INEFFICIENCIES AND HAVE DIFFICULTY MEETING DEMAND FOR OUR SERVICES.



     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 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. Our growth plan may include acquisitions. If we
acquire a company, we could have difficulty assimilating its operations, or
assimilating and retaining its key personnel. In addition if the demand for our
service exceeds our ability to provide our services on a timely basis, we may
lose customers. 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.



IF WE ARE UNABLE TO INCREASE THE CAPACITY AND MAINTAIN THE SPEED OF OUR NETWORK,
WE MAY NOT BE ABLE TO ATTRACT OR RETAIN END USERS.



     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, speeds of the data
transmission from service provider to the customer, 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 bandwidth capacity constraints
between the cable headend and the Internet backbone, the type and location of
content, Internet traffic, the number of active end users on a given

                                       11
<PAGE>   18


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, a single local area distribution point connected via
fiber-optic lines to a cable headend, 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 or increase costs
associated with customer complaints and have a material adverse effect on our
business and financial results.



OUR NETWORK MAY BE VULNERABLE TO SECURITY RISKS AND UNAUTHORIZED ACCESS TO THOSE
SYSTEMS COULD CAUSE INTERRUPTIONS, DELAYS OR CESSATION OF SERVICE TO OUR END
USERS.


     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 NEED ADDITIONAL CAPITAL IN THE FUTURE AND IT MAY NOT BE AVAILABLE ON
ACCEPTABLE TERMS.

     The development of our business may require significant additional capital
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 and to respond to competitive
pressures and perceived opportunities, such as investment, acquisition and
international expansion activities. To date, our cash flow from operations has
been insufficient to cover our expenses and capital needs. There can be no
assurance that additional financing will be available on terms favorable to us,
or at all. Moreover, Charter can require any lender with liens on our equipment
placed in Charter head ends to deliver to Charter a non-disturbance agreement as
a condition to such financings. We can offer no assurance that we will be able
to obtain secured equipment financing for Charter systems subject to such a
condition or that a potential lender will be able to negotiate acceptable terms
of non-disturbance with Charter. 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 and may need to delay the deployment of our services. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."


WE WOULD LOSE REVENUES AND INCUR SIGNIFICANT COSTS IF OUR SYSTEMS ARE NOT YEAR
2000 COMPLIANT.


     We have engaged a third-party consultant to complete a Year 2000 assessment
study by the end of May 1999, and plan to implement all necessary remediation
measures by the end of the third quarter of 1999. We are also seeking
verification from our cable partners, vendors and suppliers that they are Year
2000 compliant. Following this assessment study and after contacting these cable
partners, vendors and licensors, we will be better able to make a complete
evaluation of our Year 2000 readiness to

                                       12
<PAGE>   19

determine what costs will be necessary to be Year 2000 compliant, and to
determine whether contingency plans need to be developed. Our inability to
correct a significant Year 2000 problem, if one exists, could result in an
interruption in, or a failure of, certain of our normal business activities and
operations. In addition, a significant Year 2000 problem concerning our high
speed access services could cause our users to consider seeking alternate
providers of Internet access. Any significant Year 2000 problem could require us
to incur significant unanticipated expenses to remedy these problems and could
divert management's time and attention, either of which could have a material
adverse effect on our business, results of operation and financial condition.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Year 2000 Compliance" for information on our state of readiness,
potential risks and contingency plans regarding the Year 2000 issue.

WE MAY BECOME SUBJECT TO RISKS OF INTERNATIONAL OPERATIONS.

     We are currently at the early stages of evaluating international expansion
opportunities. If we expand internationally, 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. 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.

           RISKS RELATED TO THE MARKET FOR HIGH SPEED INTERNET ACCESS


OUR CABLE PARTNERS COULD SELL THEIR SYSTEMS OR BE ACQUIRED, WHICH COULD CAUSE US
TO LOSE CUSTOMERS.


     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 potential 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.

                                       13
<PAGE>   20


OUR CABLE PARTNERS COULD LOSE THEIR FRANCHISES, WHICH WOULD CAUSE US TO LOSE
CUSTOMERS.


     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.


WE MAY NOT BE ABLE TO COMPETE SUCCESSFULLY IN THE VERY COMPETITIVE MARKET FOR
OUR SERVICES.



     We face competition from many competitors with significantly greater
financial, sales and marketing resources, larger customer bases, longer
operating histories, greater name recognition and more established relationships
with advertisers, content and application providers and/or other strategic
partners than we have. We expect the level of this competition to intensify in
the future. We face competition from other cable modem service providers for
partnerships with cable operators and from providers of other types of data and
Internet services for end users. Due to this intense competition, there may be a
time-limited market opportunity for our cable-based high speed access services.
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.



     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. Other competitors in the cable-based
Internet access market are those companies seeking to establish distribution
arrangements with cable system operators in 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. Widespread commercial acceptance of any of these competitors'
products could significantly reduce the potential customer base for our
services, which could have a material adverse effect on our business and
financial results.



     We also compete with traditional Internet service providers and other
competing broadband technologies including ISDNs, DSLs, wireless and satellite
data services. Moreover, competitors include long distance inter-exchange
carriers, regional Bell operating companies and other local exchange carriers.
Many of these carriers are offering diversified packages of telecommunications
services, including Internet access, and could bundle these services together,
putting us at a competitive disadvantage. Widespread commercial acceptance of
any of these competing technologies or competitors' products could significantly
reduce the potential customer base for our services, which could have a material
adverse effect on our business and financial results. See
"Business -- Competition."


OUR MARKET IS CHARACTERIZED BY RAPID TECHNOLOGICAL CHANGE AND OUR SERVICES COULD
BECOME OBSOLETE OR FAIL TO GAIN MARKET ACCEPTANCE.

     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
                                       14
<PAGE>   21

prior to the time we would otherwise intend to replace it, which could 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.

WE MAY BE HELD LIABLE FOR DEFAMATORY OR INDECENT CONTENT, AS WELL AS INFORMATION
RETRIEVED OR REPLICATED.

     In part, our business involves supplying information and entertainment to
customers over the cable systems of our cable system partners. Accordingly we
face the same types of risks that apply to all businesses that publish or
distribute information, such as potential liability for defamation, libel,
invasion of privacy and similar claims, as well as copyright or trademark
infringement and similar claims. A number of third parties have claimed that
they hold patents covering various forms of online transactions or online
technologies. 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.

     The law relating to the liability of Internet and online service providers
for information carried or disseminated through their networks is unsettled.
There are some federal laws regarding the distribution of obscene or indecent
material over the Internet under which we are subject to potential liability.
These risks are mitigated by two federal laws. One, passed in 1996, immunizes
Internet service providers from liability for defamation and similar claims for
materials the Internet service provider did not create, but merely distributed.
The other, passed in 1998, creates a "safe harbor" from copyright infringement
liability for Internet service providers who comply with its requirements, which
we intend to do. These laws apply only in the United States; if we expand our
operations to other countries, our potential liability under the laws of those
countries could be greater.

WE MAY BECOME SUBJECT TO BURDENSOME GOVERNMENT REGULATION.

     The part of our business that involves installing and maintaining the
equipment used by cable systems to transmit high-speed data in a
computer-accessible format is not regulated, but cable businesses are. Changes
in cable regulations, as they relate to our service, could negatively affect our
business in several ways. First, cable operators usually classify our service as
a "cable service." If our service is not considered a cable service, some cable
franchising authorities, in most cases usually cities or counties, might claim
that our cable partners need a separate franchise to offer it. This franchise
may not be obtainable on reasonable terms, or at all. In the alternative, even
if the service is treated as cable service, local franchising authorities may
seek to impose "non-discrimination" or "open access" obligations on our cable
partners as a condition of franchise transfer or renewal. Also, even if our
service is not considered a cable service, it might be treated as a
"telecommunications service," which could subject our cable partners, and
possibly us, to federal and state regulation as "telecommunications carriers."
This could negatively affect our business in various ways. For example, if we or
our cable partners were either classified as telecommunications common carriers,
or otherwise subject to common carrier-like access and non-discrimination
requirements in the provision of our Internet over cable service, we or they
could potentially
                                       15
<PAGE>   22

be subject to government-regulated terms, conditions and prices for Internet
connection services, as well as become obligated to make contributions to the
universal service support fund. We may also provide Internet telephony services
over cable plants, and this service may be regulated in the future as a common
carrier telecommunications service. Moreover, we or our cable partners might
then have to get a "telecommunications franchise" from some localities, which
might not be available on reasonable terms, or at all. In addition, our
contracts with our cable partners make us the exclusive supplier of high-speed
data on the cable systems where our service is offered. Firms such as America
Online and large telephone companies are seeking to have regulators ban such
exclusive arrangements. If such arrangements are banned, we could face
additional competition from other Internet access providers using the cable
system to connect to their customers, which could have a material adverse effect
on our business and financial results. Finally, any future regulatory decisions
that make DSL technology services easier for competing telephone companies to
deploy over normal telephone lines, and less expensive for customers to buy,
could negatively affect our business.

WE DEPEND ON OUR KEY PERSONNEL AND MAY HAVE DIFFICULTY ATTRACTING AND RETAINING
THE SKILLED EMPLOYEES WE NEED TO EXECUTE OUR GROWTH PLANS.

     Our future success depends on the continued service of our key personnel,
especially our President, Chief Operating Officer and Chief Technology Officer.
We do not carry key person life insurance on most of our personnel. Given our
early stage and plans for rapid expansion, 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.

                         RISKS RELATED TO THE OFFERING

BECAUSE OF OUR RELATIONSHIP WITH VULCAN VENTURES, NEW INVESTORS WILL HAVE LITTLE
INFLUENCE OVER MANAGEMENT DECISIONS.

     Vulcan will beneficially own approximately 38.8% of our outstanding common
stock following the completion of the offering. Vulcan's wholly-owned
subsidiary, Charter Communications, also has warrants to purchase up to an
additional 7.75 million shares of our common stock, which become exercisable at
the rate of 1.55 shares per home passed committed to us by Charter, 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:

     - conflicts between Vulcan, as our controlling stockholder, and our other
       stockholders, whose interests may differ with respect to, among other
       things, our strategic direction or significant corporate transactions,

     - conflicts related to corporate opportunities that could be pursued by us,
       on the one hand, or by Vulcan, on the other hand, or

     - conflicts related to existing or new contractual relationships between
       us, on the one hand, and Vulcan and its other affiliates, on the other
       hand.

In particular, Vulcan is the owner of Charter, currently our largest cable
partner. Additionally, Vulcan has the exclusive right to provide or designate
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

                                       16
<PAGE>   23

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."

THE FUTURE SALE OF SHARES MAY HURT OUR MARKET PRICE.

     A substantial number of shares of our common stock are available for resale
within a short period of time after the offering. If our stockholders sell
substantial amounts of our common stock 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. See "Shares Eligible for Future
Sale."

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. In particular, 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, in addition to the concentration of ownership in Vulcan, could
make it difficult for a third party to acquire us, even if doing so might be
beneficial to you or our other 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 in the
future, there will be further dilution to new investors. See "Dilution."

                 SALE OF SHARES TO CISCO, COM 21 AND MICROSOFT


     Cisco, Com21 and Microsoft have each agreed to purchase shares of our
common stock concurrently with the offering. Cisco and Com21 are two of our
major equipment suppliers, and we recently entered into a strategic marketing
relationship with Microsoft. Each of them will purchase shares at the initial
public offering price per share, net of the underwriting discount. In addition,
each has represented that it will be purchasing such shares for investment and
not with a view to resale, and has agreed to a 180-day lock-up following the
completion of the offering. The aggregate purchase prices they will pay and the
numbers of shares of our common stock they would purchase based on the estimated
public offering price of $12.00, net of the underwriters discount, are as
follows:

</TABLE>


     We believe the sale of shares to Cisco, Com21 and Microsoft will enhance
our ongoing relationships with these key strategic partners and such strategic
relationships better position us to compete in the high speed cable modem
Internet access market.


                                USE OF PROCEEDS

     We estimate the net proceeds to us from the offering, after deducting the
underwriting discounts and offering expenses payable by us, and the sale of
$18.5 million of our common stock in the concurrent offering to Cisco, Com21 and
Microsoft, will be approximately $161.6 or $183.3 if the underwriters' exercise
their over-allotment option in full, assuming an initial public offering price
of $12.00 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 -- Risks Related to the
Offering -- 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.

                                    DILUTION


     As of March 31, 1999, our net tangible book value on a pro forma basis
giving effect to the sale of $25 million of preferred stock in April 1999 and
the conversion of all our convertible preferred stock into common stock upon
consummation of the offering was $37.3 million or $1.00 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. Immediate dilution is the
difference between the purchase price per share paid by a new investor and the
net tangible book value of each share immediately after the offering. As of
March 31, 1999, our net tangible book value, on a pro forma basis as further
adjusted for the sale of the 13,000,000 shares offered in the offering after
deducting the underwriting discounts and commissions and other estimated
offering expenses and an estimated 1,657,706 shares in the aggregate to be sold
to Cisco, Com21 and Microsoft and application of the net proceeds from such
sales of $161.6 million, would have been approximately $3.83 per share. This
represents an immediate increase of $2.83 per share to existing shareholders and
an immediate dilution of $8.17 per share to new investors which represents a
significant disparity between the price paid by new investors for the shares
sold in the offering and the net tangible book value of such shares. The
following table illustrates this per share dilution:

                                 CAPITALIZATION

     The following table sets forth our capitalization as of March 31, 1999. Our
capitalization is presented:

     -   On an actual basis; and

     -   On a pro forma basis to reflect the sale to Vulcan Ventures at $5.00
         per share of 5 million shares of Series C convertible preferred stock
         in April 1999 and a $60 million charge to accumulated deficit to
         increase the carrying value of the preferred stock to its redemption
         value.

     -   On a pro forma as adjusted basis to reflect:

        -   the sale of the 13,000,000 shares offered hereby at an assumed
            initial public offering price of $12.00 per share, after deducting
            underwriting discounts and estimated offering expenses payable by
            us;

        -   the sale of an estimated 1,657,706 shares of common stock in the
            aggregate to Cisco, Com21 and Microsoft at the assumed initial
            public offering price of $12.00, net of the underwriting discount;

        -   the automatic conversion of all outstanding shares of Series A,
            Series B and Series C convertible preferred stock into 31,000,000
            shares of common stock concurrently with the completion of the
            offering; and

        -   the issuance of 75,166 shares of common stock to the holders of our
            Series A and Series B convertible preferred stock as a payment in
            kind for outstanding dividends.

                            SELECTED FINANCIAL DATA
            (DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

     The balance sheet data at December 31, 1998 and the statement of operations
data for the period from April 3, 1998 (Inception) through December 31, 1998
have been derived from financial statements audited by PricewaterhouseCoopers,
LLP, independent accountants appearing 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 after the acquisitions or the future results that
we will experience.

     The selected financial data at March 31, 1999 and for the three months then
ended have been derived from unaudited financial statements appearing elsewhere
in this prospectus. The unaudited financial statements include all adjustments,
consisting only of normal recurring adjustments, which we consider necessary for
the fair presentation of our financial position and results of operations for
this period. Operating results for the three months ended March 31, 1999 are not
necessarily indicative of the results that we will experience for the entire
year. Historical results are not necessarily indicative of the results to be
expected in the future.


     The pro forma basic and diluted net loss per share for the historical
period April 3, 1998 through December 31, 1998 and for the three months ended
March 31, 1999 gives effect to the assumed conversion of our Series A and Series
B convertible preferred stock into shares of common stock at the date the shares
of convertible preferred stock were issued. The pro forma basic and diluted net
loss per share for the combined pro forma year ended December 31, 1998 assumes
that (a) our Series A convertible preferred stock had been issued on January 1,
1998 and immediately converted into shares of common stock and (b) that our
Series B convertible preferred stock had been immediately converted into common
stock upon the respective dates of issuance of the Series B convertible
preferred stock. As a result of such assumed conversions, dividends and
accretion of redemption value of the preferred stock are excluded from the net
loss available to common stockholders.

                    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 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 local
       telephone company's central office 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.

                                       24
<PAGE>   31

     - General and administrative expenses, which consist primarily of salaries
       for our executive, administrative, finance and human resource personnel;
       amortization of goodwill; and fees for 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.

     - Non-cash compensation expense from the issuance of stock options which
       equals the excess of the fair market value of our stock at the time of
       grant over the exercise price of the stock options granted to employees
       and directors amortized over the vesting period.

RESULTS OF OPERATIONS FOR THE PERIOD APRIL 3, 1998 (INCEPTION) TO DECEMBER 31,
1998 AND FOR THE THREE MONTHS ENDED MARCH 31, 1999 (UNAUDITED)

     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 discussion
reflects our results of operations since April 3, 1998.

  Revenues.  Net revenue consists primarily of net monthly subscription fees for
cable modem-based and traditional dial-up Internet services, and cable modem
rental income. Total net revenue was $337,000 for the period April 3, 1998
(Inception) to December 31, 1998 ("Inception Period") and $299,000 for the first
quarter of 1999. For the Inception Period, cable modem based subscription fees
contributed approximately 45% of the net revenue, traditional dial up services
contributed 35% and cable modem rental and installation fees each contributed
approximately 10%. For the first quarter of 1999, cable modem based subscription
fees contributed approximately 48% of our net revenue, traditional dial up
services contributed 35%, cable modem rental fees contributed 15% and
installation charges contributed 2%.

  Costs and Expenses

     Operating. Operating costs were $2.1 million for the Inception Period and
$2.1 million for the first quarter of 1999. During each period, we incurred
significant personnel cost to staff our network operations center and help desk
on a full-time basis. Telecommunications expenses were significant for the
periods as we rolled out our service to new markets.

     Engineering. Engineering expenses were $2.3 million for the Inception
Period and $1.5 million for the first quarter of 1999. During each 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
Inception Period and $2.0 million for the first quarter of 1999. During the
periods 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 Inception Period and $1.3 million for the first quarter of 1999.
During the periods we hired personnel to implement procedures and controls to
support our planned expansion and to administer finance, legal and human
resource functions. General and administrative expenses also included
amortization of goodwill of $626,000 for the Inception Period and $212,000 for
the first quarter of 1999 resulting from our acquisitions of CATV.net and High
Speed Access Network.

     Non-cash Compensation from the issuance of Stock Options. Non-cash
compensation expense from the issuance of stock options for the first quarter of
1999 was $1.5 million which represents the excess of the fair market value of
our common stock over the exercise price of the stock options granted. This
expense is principally related to 189,875 options issued to our directors in
January 1999 which immediately

                                       25
<PAGE>   32

vested. In addition, we will recognize expense in future periods, principally
related to the issuance of 140,740 options to employees in January 1999. The
amount of this compensation expense is recognized over the vesting period of the
option, which is generally five years. Upon completion of this offering, a
non-cash stock compensation charge of approximately $1.1 million will be
recognized for stock options which vest contemporaneously with the offering.

     We also could incur material non-cash charges related to the issuance of
warrants to our cable partners. We 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 operator. The amount of any such
charges is not determinable until such warrants are earned.

     Net Interest Income.  Net interest income was $40,000 for the Inception
Period and $119,000 for the first quarter of 1999. 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 from April 3, 1998 (Inception) through March 31, 1999.

QUARTERLY RESULTS OF OPERATIONS

     The following table sets forth certain statement of operations data for our
four most recent fiscal quarters. This information has been derived from our
unaudited financial statements. In our opinion, this information has been
prepared on the same basis as the annual consolidated financial statements and
includes all adjustments, consisting only of normal recurring adjustments,
necessary for a fair presentation of the results of operations for such periods.

     Net revenues increased in each quarter as a result of the expansion of our
services.

                                       26
<PAGE>   33

     Quarterly expenses increased sequentially 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. Total cost and expenses for the first quarter
of 1999 increased 173% in comparison to the quarter ended December 31, 1998. The
company increased its business activities and expanded its workforce due to the
rollout of our services in the Charter systems and to increase our capacity to
rollout service into new markets. Also, a $1.5 million non-cash charge related
to the grant of compensatory stock options contributed to the increase in
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 and for the first quarter of 1999. Cash used in
operating activities was $7.2 million for the Inception Period and $4.8 million
for the first quarter of 1999. 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, accrued
expenses and other current liabilities of $1.6 million. In the first quarter of
1999, the use of cash was primarily due to a net loss of $8.0 million, offset by
non-cash expenses of $2.4 million and $800,000 in net changes in assets and
liabilities.

     Cash used in investing activities was $3.3 million for the Inception Period
and $5.7 million for the first quarter of 1999. Cash used for investing
activities for these periods was primarily the result of capital expenditures.
Capital expenditures were $4.2 million for the Inception Period and $5.5 million
for the first quarter of 1999. The principal capital expenditures incurred
during these periods were for the purchase of headend data network hardware and
software, cable modems and equipment necessary for monitoring our network. The
higher level of capital expenditures during the first quarter of 1999 reflects
our expansion into new markets. During the Inception Period, $907,000 of the
capital expenditures were funded with cash acquired in the acquisition of
CATV.net and High Speed Access Network.

     Cash provided by financing activities was $28.4 million for the Inception
Period resulting primarily from $27.6 million in net proceeds from the issuance
of convertible preferred stock. Cash used by financing activities for the first
quarter of 1999 was $17,000 resulting from payments on long-term debt and
capital lease repayments.

     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:

     - The pace of the rollout of our service to our cable partners, including
       the impact of substantial capital expenditures and related operating
       expenses;

     - 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;

     - Price competition in the Internet and cable industries;

     - Capital expenditures and costs related to infrastructure expansion;

                                       27
<PAGE>   34

     - 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.

We expect to incur approximately $20 million of capital expenditures in 1999
principally related to the installation of headend data network hardware and
software, cable modems, central network hardware and software for e-mail,
network monitoring and web hosting and a billing and customer care system.
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, which requires us to purchase headend data network
hardware and software.

     Since inception, we have financed our operations primarily through a
combination of private sales of equity securities and capital equipment leases.
At March 31, 1999, the primary source of our liquidity was $7.3 million of cash
and cash equivalents. We believe that the net proceeds from this offering,
together with existing cash, $18.5 million in proceeds from the sale of common
stock to Cisco, Com21 and Microsoft, $25 million in proceeds from the sale of 5
million shares of Series C preferred stock to Vulcan Ventures in April 1999,
proceeds from a $3.0 million loan facility entered into in April 1999 and
capital lease financing will be sufficient to meet our working capital
requirements, including operating losses, and capital expenditure requirements
for the next 18 months, assuming we achieve our business plan. 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 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 upon which we are dependent
to conduct our operations are not Year 2000 compliant. Should any of our "date
dependent" equipment, circuits or software fail as a result, our services could
be severely affected. Our potential areas of exposure include

                                       28
<PAGE>   35

information technology, including computers and software that we purchase or
licenses from third parties, and non-information technology, such as telephone
systems and other equipment that we acquire and use internally. Other potential
areas of exposure include the systems of business partners upon whom our
services are dependent, including our cable partners and their RF-cable TV
plants, and Internet backbone providers and telephone companies.

     We have engaged a third party consultant to perform a Year 2000 assessment
study. The planning, inventory, and business impact analysis portions of our
Year 2000 assessment project are complete.

     - We have tested most of our internal PC-based or other local area computer
       networks, and expect to complete the balance of this testing by May 31,
       1999. We have identified only minor issues that we will remediate by
       routine upgrades, patches and replacements by the end of the second
       quarter 1999.

     - We have begun and are continuing to interview and seek verification from
       our cable affiliates that the cable plants over which our service
       operates are Year 2000 compliant. Our major cable partner, Charter
       Communications, Inc., has indicated that it expects to be fully Year 2000
       compliant by August 31, 1999. Our other cable partners are in various
       states of Year 2000 readiness and planning, but we believe the risk posed
       to our services by our cable partners' head end equipment to be slight.
       To the extent our cable partners are not presently compliant, we are
       asking them to provide us with a description of their plans to become so.
       To the extent that our cable affiliates fail to provide certification
       that they are Year 2000 compliant by August 30, 1999, we will reassess
       the possible impact on our business and the nature of our electronic
       interdependencies at that time, and take appropriate remediation action
       to the extent possible.

     - We are also verifying that the equipment, systems and services of our
       other vendors and suppliers provide to us are Year 2000 compliant. To
       date, virtually all of the non-software vendors and suppliers that we
       consider vital to our operations have certified Year 2000 compliant
       status to us, or have indicated that they will do so by July 31, 1999. To
       the extent that vendors fail to provide certification that they are Year
       2000 compliant by August 30, 1999, we expect to terminate and replace
       those relationships.

     We expect to resolve our 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 to develop and implement our Year 2000 compliance
assessment plan will not exceed $250,000, which will be funded from cash on
hand.

     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, including
our web sites, could be unavailable to deliver services to our cable affiliates
and customers. This in turn could expose us to claims and liabilities of unknown
and potentially material proportions. We are currently working on specific
contingency plans to deal with the worst-case scenario that might occur if
technologies we are dependent upon are not Year 2000 compliant and fail to
operate effectively, and expect to have those plans in place by the end of the
second quarter of 1999. But 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 20 cable operators,
covering 51 systems and approximately 982,000 homes passed. The term "homes
passed" refers to the number of homes that potentially can be served by a cable
system. We also have non-binding letters of intent with another 14 operators
representing an additional 23 systems and approximately 303,000 homes passed.
Under these letters of intent we have the exclusive right to negotiate with
these operators for a limited period of time to provide our services. We have
commenced full operations in 21 systems covering approximately 319,000 homes
marketed, initiated operations in another 21 systems covering an additional
402,000 homes, and have approximately 3,900 high speed 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., one of the ten 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 Charter has an equity incentive to
provide us up to an additional 5 million homes passed.

     We recently signed a letter of intent with ServiceCo LLC, which provides
the Road Runner high speed online and content aggregation services. Under the
non-binding letter of intent, we and ServiceCo have agreed to negotiate in good
faith toward an agreement under which we would provide our turnkey service as a
Road Runner subcontractor to cable systems we jointly designate. In connection
with this agreement, we also expect to grant Road Runner warrants to purchase up
to 5 million shares of our common stock at an exercise price of $5 per share
based upon the number of homes passed to which we provide our joint services.

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 982,000 homes passed and we have letters of intent
relating to approximately 303,000 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 Road Runner. Although several of
the operators who have contracted with @Home and Road Runner 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
                                       30
<PAGE>   37

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 to provide our service in some of these
exurban markets by partnering with the cable operator directly or with another
high speed Internet access provider.

     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 an internally
developed high speed Internet access service without the assistance of an
outsourced 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 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 42 cable systems we
                                       31
<PAGE>   38

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 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. As with our cable-based access services, we bear the capital and
operating costs associated with providing these services. 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 is a competitively
priced alternative to other high speed technologies such as ISDN, DSL, wireless
and satellite. In two-way cable systems, the cost of our service to the end user
is approximately the cost of standard dial-up Internet access plus the

                                       32
<PAGE>   39

cost of an additional phone line. In addition, cable based Internet access is
capable of significantly faster speeds than competing technologies, and is
better suited for the exurban market where ISDN and DSL service offerings are
limited.

     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;
                                       33
<PAGE>   40

     - Management believes the potential penetration in these markets may be
       higher than in urban markets; and

     - 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. We may also provide services on a less than
full turnkey basis.

     Rapidly Expand Our Base of Cable Partners. We have installed 42 systems,
covering 721,000 homes passed, and we have contracts or letters of intent to
deploy our services in an additional 32 systems, covering 564,000 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. A large
multiple system operator may operate cable systems in both urban and exurban
markets.

     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. 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 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 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

     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, one of the ten largest
cable system operator in the United States, and has substantial investments in
media, Internet and new media companies, including Go2Net, Inc., USA Networks,
ZDTV, Beyond.com, N2K, Inc., Northpoint Communications, 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 are
selectively evaluating 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.

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 an additional $9.95 per month.
Almost all of our high speed access end users currently rent a cable modem from
us. 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 service, 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 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

                                       35

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, 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
provide and earn revenues from telephony services is subject to our agreements
with Vulcan Ventures. See "Risk Factors" and "Certain Transactions."

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 319,000 homes passed, are implementing services to approximately
402,000 additional homes passed and have contracts and letters of intent
covering an additional 564,000 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. Most of our
network services agreements provide for a five-year exclusive term from the date
we commence full operation within the cable system.

     The following table summarizes cable partners with whom we have contracts,
the number of homes passed and the areas served by each cable partner's systems
as of April 29, 1999:

     We have approximately 3,900 high speed cable modem end users and
approximately 3,400 dial-up end users. Approximately 1,506, or 39.0% of our high
speed cable modem end users and approximately 290, or 8.5% of our dial-up end
users are from cable systems affiliated with Charter.

     Cisco Systems, Inc. Cisco, one of our major equipment suppliers, has agreed
to purchase $7.5 million of our common stock at the initial public offering
price, net of the underwriting discount, concurrently with this offering.

     Road Runner. We recently signed a non-binding letter of intent with
ServiceCo LLC, the entity that provides Road Runner's cable Internet access and
content aggregation service. Under the letter of intent, we and ServiceCo have
agreed to negotiate in good faith toward an agreement under which we would
provide our service as a Road Runner subcontractor to cable systems we jointly
designate to receive our services. In addition to the revenue split we would
share with ServiceCo and the cable operator, we would grant ServiceCo warrants
to purchase one share of our common stock at a price of $5 per share for each
home passed that we jointly designate to receive our services, up to a maximum
of 5 million shares. Additionally, ServiceCo would be entitled to provide its
Road Runner content in the designated systems.

     Microsoft. We have a non-binding letter of intent with Microsoft
Corporation covering a number of potential areas of strategic relationship. No
assurance can be given that we will sign a definitive agreement with Microsoft
for any or all of the items of strategic relationship or that a definitive
agreement will be of material benefit to us. Microsoft has agreed to assist us
in marketing HSA services to multiple system cable operators. We also issued a
warrant to Microsoft to purchase 250,000 shares of common stock at 125% of the
initial public offering price, exercisable until May 2004. This warrant will
provide Microsoft the right to purchase one additional share of our common stock
for each additional 10 homes passed above 2.5 million homes Comcast Corp.
commits to us by May 1, 2002. Microsoft has agreed to purchase $10 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, Microsoft would purchase 896,057 shares of our common stock.

     National Cable Television Cooperative. We recently signed an agreement with
the National Cable Television Cooperative, an organization which represents over
950 multiple system operators with approximately 10 million cable customers in
all 50 states. Under the agreement, cable operators who are members of the
cooperative will have the ability to take and offer our services to their
subscribers under standardized terms and conditions.

     Vulcan Ventures. Vulcan Ventures, which owns Charter, beneficially owns
54.2% of our common stock before the offering. Charter is one of the ten largest
cable system operator in the United States. Charter has already committed to us
approximately 765,000 homes passed. We granted Vulcan warrants to purchase up to
7.75 million shares of our common stock for $3.23 per share. These warrants,
which Vulcan has assigned to Charter, become exercisable at the rate of 1.55
shares of common stock per home passed committed to us by Charter in excess of
750,000.

     Com21, Inc. Com21, one of our major equipment suppliers, has agreed to
purchase $1.0 million of our common stock at the initial public offering price,
net of the underwriting discount, concurrently with the offering.

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.

     Approximately 53% of our current end users are cable modem users, and 47%
are dial-up users.

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 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

                                       40
<PAGE>   47

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 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 point-to-point wireless or 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. Using these widely available network devices, we
provide the necessary system integration required to install our service at the
cable headend.

     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

                                       41
<PAGE>   48

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 primarily for partnerships with cable operators from
other cable modem-based providers of Internet access services and 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, Road Runner, the ISP Channel, Online System Services, Inc.,
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 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 Road Runner, 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
                                       42
<PAGE>   49

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 the 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.

GOVERNMENT REGULATION

     Our business has two main parts. First, we will supply information and
entertainment to customers over the cable systems of our cable system partners.
This information and entertainment will include materials that we obtain from
third parties (including Vulcan Ventures and its affiliates) as well as
information generally available on the Internet that our customers will reach by
means of our service. Second, we will install and maintain the equipment needed
to transmit that information to customers over the cable systems of our cable
partners in a form that can be understood by customers' personal computers.
There are certain risks associated with both aspects of this business.

     With regard to supplying information, we are subject to the same types of
risks that apply to all businesses that publish, broadcast or distribute
information. These include potential liability for defamation, libel, invasion
of privacy and similar claims, as well as potential liability for copyright or
trademark infringement and similar claims. In addition, the law relating to the
liability of Internet and online service providers for information carried on or
disseminated through their networks is unsettled. There are also some specific
federal laws regarding the distribution of obscene or indecent content by means
of communications facilities (including distribution of such content to minors)
under which we are subject to potential liability. These risks are mitigated to
some extent by a federal law passed in 1996 that immunizes Internet service
providers from legal liability for defamation and similar claims in connection
with information that the Internet service provider did not itself create. The
law regarding these issues is controversial, and could be changed in ways that
would expose us to greater liability. Also, the Digital Millennium Copyright
Act, passed in 1998, creates a "safe harbor" from copyright infringement
liability for Internet service providers who meet its requirements, which we
intend to do. Finally, if we expand our operations to other countries with less
extensive legal protections for publishers and speakers, our potential liability
for our activities in those countries could be much greater than in the United
States.

     The other main aspect of our business -- installing and maintaining the
equipment needed to permit cable systems to transmit information in a
computer-accessible format -- is not currently regulated by state or federal
governments. Even so, the business of our cable partners is subject to
regulation by the federal government and by local governments (which issue
franchises to cable systems) in accordance with federal law. There are four main
ways that these regulations could change that might severally and negatively
affect our business.

     First, our service is generally classified by cable operators as a "cable
service." This means that our cable partners may offer our service over their
cable systems under their present franchise rights. If our service is not a
cable service, then some franchising authorities (usually cities or countries)
might claim that our cable partners need separate authorization to offer it.
This separate authorization may not be obtainable on reasonable terms, or at
all. In the alternative, even if the service is treated as cable service,

                                       43
<PAGE>   50

local franchising authorities may seek to impose "non-discrimination" or "open
access" obligations on our cable partners as a condition of franchise transfer
or renewal.

     Second, if our service is not a "cable service," it could be reclassified
as a "telecommunications service." This could subject our cable partners (and
possibly us) to regulation as "telecommunications carriers" at the state and
federal level. For example, if we or our cable partners were either classified
as telecommunications common carriers, or otherwise subject to common
carrier-like access and non-discrimination requirements in the provision of our
Internet over cable service, we or they could potentially be subject to
government-regulated terms, conditions and prices for Internet connection
services, as well as become obligated to make contributions to the universal
service support fund. We may also provide Internet telephony services over cable
plant, and this service may be regulated in the future as a common carrier
telecommunications service. It is not clear what impact compliance with those
regulations would have on our business, but the impact could be severe.
Moreover, we or our cable partners might then have to get a "telecommunications
franchise" from some localities. This franchise might not be available on
reasonable terms, or at all.

     Third, we have exclusive contracts with our cable partners to be the only
supplier of high-speed data on the cable systems where our service is offered. A
variety of parties, including firms with much greater resources than ours, are
trying to have such exclusive arrangements banned. If they are successful, cable
systems might have to accommodate several suppliers of high-speed data services
and we could face additional competition from such other suppliers. We believe
that our exclusive arrangements are very valuable to our business. If such
arrangements are banned, the impact on our business could be severe.

     Fourth, regulatory action could create a more favorable environment for our
competitors than exists today. For example, it is possible to send high-speed
data over many normal telephone lines using a technology called "digital
subscriber line" or "DSL." This technology may be used either by the existing
telephone company that owns the telephone lines, or by competing telephone
companies that have the right to lease those lines. Regulatory decisions that
make DSL services easier for competing telephone companies to deploy, and less
expensive for customers to buy, would negatively affect our business.

EMPLOYEES

     As of April 15, 1999, we employed 207 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 1,395,000 shares of common stock for issuance under the plan.
Options to purchase 839,325 shares of common stock have been granted under the
plan, at a weighted average exercise price of $1.67 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 of directors
elected not to grant additional options under the plan.

     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.

                                       50
<PAGE>   57

     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) by delivering shares of common stock owned by the participant; 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 the closing of 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.

     Tax Consequences.  The following description of the tax consequences of
awards under the 1998 stock option plan is based on present federal tax laws and
does not purport to be a complete description of the tax consequences of the
1998 stock option plan.

     There are generally no federal tax consequences as to the optionee or to us
upon the grant of an option. On the exercise of an incentive stock option, the
optionee will not recognize any income, and we will not be entitled to a
deduction for tax purposes, although such exercise may give rise to liability
for the optionee under the alternative minimum tax provisions of the Internal
Revenue Code. However, if the optionee disposes of shares acquired upon the
exercise of an incentive stock option within two years of the date of grant or
one year of the date of exercise, the optionee will recognize ordinary income,
and we will be entitled to a deduction for tax purposes in the amount of the
excess of the fair market value of the shares of common stock on the date of
exercise over the option exercise price (or the gain on sale, if less); the
remainder of any gain, and any loss, to the optionee will be treated as capital
gain or loss to the optionee. On the exercise of a nonqualified stock option,
the amount by which the fair market value of common stock on the date of the
exercise exceeds the option exercise price will generally be taxable to the
optionee as ordinary income and will generally be deductible for tax purposes by
us. The disposition of shares acquired upon exercise of a non-qualified option,
or an incentive stock option, if after the one year and two year periods
described above, will generally result in capital gain or loss to the optionee
but will have no tax consequences to us.

     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 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>   58

     1999 Stock Option Plan

     We adopted the 1999 Stock Option Plan in January 1999. The plan provides
for grants of options to our designated employees, officers and directors.

     General. The plan authorizes options to purchase up to 3,100,000 shares of
common stock for issuance. The maximum number of shares for which options may be
granted to any individual in any calendar year will not exceed 465,000. 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
       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.

     Types of 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 April 29, 1999, we had granted options to purchase
46,500 shares at an exercise price of $3.23 per share and 21,000 shares at an
exercise price equal to the initial public offering price per share. In
addition, we expect to issue options for an additional 465,065 shares at an
exercise price equal to the initial public offering price per share
contemporaneously with the offering.

     Terms of Options. 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 will be equal to or
greater than the fair market value of a share of common stock on the date the
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) by delivering shares of common stock owned by the participant; or

     (3) by any other method 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 which may
be up to a maximum of ten years from the date of grant, except that the term of
an incentive stock option granted to an
                                       52
<PAGE>   59

employee who owns more than 10% of the common stock may not exceed five years
from the date of grant.

     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 as of the participant's next vesting date so that they
become exercisable prior to the consummation of the change of control 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 or an affiliate of Vulcan).

     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.

     Tax Consequences. The tax consequences of options granted under the 1999
stock option plan will generally be the same as the tax consequences of options
granted under the 1998 stock option plan.

     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 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. 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 it is intended that 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
April 29, 1999, options to purchase 189,875 shares at an exercise price of $3.23
per share were outstanding under the plan. Under the plan, each non-employee
director is automatically granted an option to purchase 27,125 shares of our
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
11,625 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 465,000 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.

                              CERTAIN TRANSACTIONS

     Ron Pitcock and Kent Oyler, 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
February 1998, CATV.net, Inc., our subsidiary following our formation in April
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. CATV.net issued the shares to OPM Services, the Colorado Limited
Partnership and the Gibbs Family Limited Partnership in exchange for their units
of CATV.net, LLC, in connection with the reorganization of the LLC as a
corporation. The LLC units were originally issued to Mr. Gibbs and Mr. Oyler for
nominal consideration upon the formation of the LLC. Additional units were
issued to Mr. Oyler in consideration of the cancellation of $117,000 due Mr.
Oyler. In April 1998, the shares of CATV.net issued to OPM Services and the
Colorado Limited Partnership were exchanged for 1.55 million shares of our
common stock and the shares of CATV.net issued to the Gibbs Family Limited
Partnership were exchanged for 1.55 million shares of our common stock in
connection with our formation and the reorganization of CATV.net as our
subsidiary. OPM Services, the Colorado Limited Partnership and the Gibbs Family
Limited Partnership are entitled to certain registration rights with respect to
their shares of common stock. See "Description of Securities--Registration
Rights". In April 1998, High Speed Access Network, Inc., our subsidiary
following our formation, 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 for nominal consideration. The shares of common stock
of High Speed Access Network issued to the Pitcock Family Limited Partnership
and to Mr. Gans were exchanged for 1.5 million and 1.3 million shares
respectively of our common stock in April 1998 in connection with our formation
and the reorganization of High Speed Access Network as our subsidiary.

     Since our formation we have issued 20 million shares of convertible
preferred stock, which will automatically convert into 31 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. We estimate that as of March 31, 1999 the holders of the
convertible preferred stock would have received 75,166 shares of common stock in
payment of the accrued and unpaid dividends. The holders of common stock issued
upon conversion of the convertible preferred stock are entitled to registration
rights. See "Description of Securities--Registration Rights".

     From April to November 1998 we sold 5 million shares of Series A
convertible preferred stock to Broadband Solutions, LLC and 2 million shares of
Series B convertible preferred stock to Broadband Solutions II, LLC. The
purchase price of $1.00 per share, $5 million in the aggregate, for the Series A
convertible preferred stock was paid in cash. The purchase price of the Series B
convertible preferred stock of $2.50 per share, $5 million in the aggregate, was
paid in cash and/or in exchange for a note owing to Broadband. In December 1998
and April 1999, Broadband Solutions, LLC and Broadband Solutions II, LLC
distributed the 5 million shares of Series A convertible preferred stock and the
2 million shares of Series B convertible preferred stock to their members. Until
the completion of the offering, Broadband Solutions, LLC will have voting power
with respect to the Series A convertible preferred stock and Series B
convertible preferred stock pursuant to irrevocable proxies granted to it by the
members of Broadband Solutions, LLC and Broadband Solutions II, LLC and by River
Cities Capital Fund Limited Partnership, a former member. David A. Jones, Jr.,
our Chairman of the Board, is the managing member, 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 them are members of Broadband Solutions, LLC
and Broadband Solutions II, LLC. These entities are entitled to registration
rights with respect to the shares of common stock to be issued upon conversion
of the convertible preferred stock owned by them. See "Description of
Securities--Registration Rights".

     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

                                       55
<PAGE>   62

of directors. Mr. Jones is the Chairman and Mr. Saunders is the Senior Managing
Director of Chrysalis Ventures. In 1998, we accrued $60,000 payable to Chrysalis
Ventures under the consulting 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. Charter has an equity incentive to provide us additional homes
passed, although it is not obligated to do so. Charter can terminate our
exclusivity rights, on a system-by-system basis, if we fail to meet performance
benchmarks relating to various equipment maintenance, operations and reporting
obligations or otherwise breach our agreement, including our commitment to
provide content designated by Vulcan. 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 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 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 $20 million in 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. In April 1999, Vulcan purchased the entire 5 million shares
of Series C convertible preferred stock for $25 million in cash. The shares of
Series B and Series C convertible preferred stock issued to Vulcan will
automatically convert at a price of $3.23 per share into 20.15 million shares of
common stock upon completion of this offering. Vulcan is entitled to
registration rights with respect to the shares of common stock to be issued upon
conversion of the Series B and Series C convertible preferred stock owned by it.
See "Description of Securities--Registration Rights."

     As an inducement to Vulcan to cause Charter to commit additional systems to
us, we granted Vulcan warrants to purchase up to 7.75 million shares of our
common stock at a purchase price of $3.23 per share. Vulcan subsequently
assigned the warrants to Charter. The warrants are exercisable by Charter at the
rate of 1.55 shares of common stock for each home passed committed to us by
Charter in excess of 750,000. 3.9 million warrants may be earned by Charter on
or before July 31, 2001 and must be exercised on or before July 31, 2002. 3.9
million warrants may be earned by Charter on or before July 31, 2003 and must be
exercised on or before July 31, 2004. 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 Securities -- Registration Rights".

     In February 1998, CATV.net, Inc. and OPM Services, Inc., an entity
controlled by Kent Oyler, 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 three 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.

                                       56
<PAGE>   63

     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 formed Darwin Networks, Inc. a wholly-owned subsidiary,
and transferred to Darwin all of the assets used in our digital subscriber line
technology division in exchange for 4 million shares of Darwin common stock. We
subsequently distributed the 4 million shares of Darwin common stock to our
stockholders. In the distribution, Vulcan received 2,166,667 shares, Broadband
Solutions, LLC received 488,125 shares, Broadband Solutions II, LLC received
423,042 shares, OPM Services received 55,555 shares, the Colorado Limited
Partnership received 111,111 shares, the Gibbs Family Limited Partnership
received 166,667 shares and the Pitcock Family Limited Partnership received
163,333 shares. As of March 31, 1999, the date of the distribution to
stockholders, the outstanding shares of Darwin common stock were valued at
approximately $0.24 per share. The distribution of the Darwin shares to our
existing stockholders resulted in a $549,000 reduction in our net operating loss
carryforward.

     In connection with the transaction, we agreed to provide Darwin various
financial, accounting and other professional staff services and will be
compensated for our costs at fair market value. The services agreement is for an
initial six month term, and may be terminated on 30 days notice by us or Darwin.
We also entered into an agreement with Darwin under which Darwin agreed to
provide us the deployment of digital subscriber line technology in our systems,
as needed and requested by us from time to time, at negotiated rates. We also
agreed to loan Darwin up to $500,000 for working capital pursuant to a six month
unsecured revolving credit note bearing interest at the prime rate. The note is
payable by Darwin on September 15, 1999. In connection with the note, Darwin
issued us a warrant to purchase 1 million shares of Darwin common stock at an
exercise price of $5.00 per share. The warrant is exercisable for a period
commencing on March 15, 1999 and ending on the earlier of March 15, 2004 or the
completion of an initial public offering by Darwin. Four of our directors, David
A. Jones, Jr., Michael E. Gellert, Robert S. Saunders and William D. Savoy, are
also directors of Darwin. David F. Gibbs, a current stockholder and former
officer of HSA, is the President of Darwin.

     For information regarding the grant of stock options to executive officers
and directors, see "Management--Compensation of Directors," "--Stock Option
Plans" and "Principal Stockholders."


     We believe that the above transactions were entered into on terms no more
favorable than they would have been had they been entered into with unrelated
third parties.

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.

CLASS A COMMON STOCK


     Our board of directors, without further action by the stockholders, is
authorized to issue an aggregate of 100 million shares of Class A common stock.
Upon completion of this offering, no shares of Class A common stock will be
outstanding and we have no plans to issue any Class A common stock. Our board of
directors may, by resolution of 66 2/3% of the directors then in office, without
stockholder approval, issue Class A common stock in one or more series and fix
the designations, powers, preferences and rights of the shares, provided that
any series of Class A common stock issued will either be nonvoting or will have
voting rights junior to the common stock and will be pari passu with the common
stock upon liquidation. Issuances of Class A common stock 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.


PREFERRED STOCK


     Our board of directors, without further action by the stockholders, is
authorized to issue an aggregate of 10 million 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, by resolution of 66 2/3% of the directors then in office, 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 3.1 million shares of common stock may be
granted under the 1999 stock option plan and options to purchase 465,000 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 257,375 shares
of common stock under these plans and 839,325 shares of common stock under the
1998 stock option plan. Of the total options outstanding, options to purchase
1,029,200 shares will be exercisable upon the closing of this offering. In
addition, we intend to issue options to purchase 465,065 shares of common stock
under the 1999 stock option plan at an exercise price equal to the initial
public offering price per share contemporaneously with this offering. Any shares
issued upon exercise of these options will be immediately available for sale in
the public market 90 days after the date of this prospectus or upon our filing
of a registration statement after the offering relating to our stock option
plans, subject to the

                                       61
<PAGE>   68

terms of lock-up agreements entered into between certain of 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 Charter to purchase 7.75 million shares of common stock at
a purchase price of $3.23 per share. The warrants are exercisable on the basis
of 1.55 shares 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 3.9
million shares if they do not become exercisable on or before July 31, 2001, and
as to 3.9 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 in a committed system is reduced. As of April 29,
1999, Charter had earned warrants to purchase 22,971 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; 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".

     We have also issued a warrant to Microsoft to purchase 250,000 shares of
common stock at 125% of the initial public offering price, exercisable until May
2004. The warrant provides Microsoft the right to purchase one additional share
of our common stock for each additional 10 homes passed above 2.5 million homes
Comcast commits to us by May 1, 2002.

     In March 1999, we issued warrants to purchase 20,150 shares of our common
stock at a purchase price of $6.45 per share in connection with our acquisition
of the assets of Atlanta Online InterNet, Inc.

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 have entered into registration rights agreements with certain of our
stockholders. After the completion of this offering, the holders of 31 million
shares of common stock issuable upon the conversion of all of the outstanding
preferred stock, and warrants to purchase an additional 7.75 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. These holders are also entitled to require us to
include their registrable securities in future registration statements that we
may file. In addition, after the completion of the offering, the holders of 3.1
million shares of common stock may demand that we register up to 20% of their
shares 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 outstanding 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.

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.

                                       63
<PAGE>   70

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 to us or our stockholders, 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.

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.

     We have entered into agreements to indemnify our executive officers and
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.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is American
Securities Transfer & Trust, Inc., Denver, Colorado.

                        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 citizen or resident of the United States,

     - a corporation or partnership created or organized in the United States or
       under the laws of the United States or of any state, or

     - an estate whose income is includable in gross income for United States
       federal income tax purposes regardless of its source, or

     - a trust if a court within the United States is able to exercise primary
       supervision over the administration of the trust and 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, assuming we have, and to the extent of, tax earnings
and profits at the time of any dividends, 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 the 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.

                                       65
<PAGE>   72

     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 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

     - the gain is not U.S. trade or business income,

     - 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,

     - 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

     - 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

                                       66
<PAGE>   73

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

     - a "controlled foreign corporation" for U.S. federal income tax purposes,

     - 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,

     - 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

     - certain U.S. branches of foreign banks or insurance companies.

     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 51.9 million 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 13 million shares sold in the offering
and the 1.7 million shares to be sold to Cisco, Com21 and Microsoft 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 37.2 million 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 519,000 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 1,096,700
shares of common stock are outstanding under our stock option plans, 1,029,200
of which will be exercisable upon completion of the offering and warrants to
purchase a total of 8.1 million shares of common stock are outstanding. In
addition, we intend to issue options to purchase 465,065 shares of common stock
under the 1999 stock option plan at an exercise price equal to the initial
public offering price per share contemporaneously with the completion of this
offering. See "Management--Compensation of Directors" and "--Stock Option
Plans."

     We and our directors, officers, substantially all current stockholders,
holding an aggregate of 37.2 million shares of common stock and warrants to
purchase up to 7.75 million shares of common stock, and Cisco, Com21 and
Microsoft 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 the holders of 5.5 million shares may transfer these
shares by gift provided that the donee signs a similar lock up agreement, and 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 34.1 million shares of our outstanding
common stock and holders of warrants to purchase up to 7.75 million shares of
common stock will have 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 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 1,950,000 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 proportionate to

                                       69
<PAGE>   76

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 34.1 million shares of common stock and warrants to
purchase 7.75 million shares of common stock, and Cisco, Com21 and Microsoft
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 the holders of 5.5 million shares may transfer these shares by gift
provided that the donee signs a similar lock up agreement and 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 that issuance provide that the 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" and "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 liabilities related to
the offering, including liabilities under the Securities Act, and to contribute,
under defined 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
transactions that stabilize the price of common stock. These 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 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 those 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

                                       70
<PAGE>   77

engage in these stabilizing transactions or that these 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 a
sale is made.

     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
of this prospectus.

     At our request, the underwriters have reserved up to 7.5% 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. These 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 these
persons purchase such reserved shares.

                                 LEGAL MATTERS

     The validity of the shares of common stock offered hereby will be passed
upon for us by Brobeck, Phleger & Harrison LLP, Denver, Colorado. Certain legal
matters in connection with the offering will be passed upon for the underwriters
by Weil, Gotshal & Manges LLP, New York, New York.

                       REPORT OF INDEPENDENT ACCOUNTANTS

Board of Directors
High Speed Access Corp.

     The recapitalization described in Note 14 to the consolidated financial
statements has not been consummated at May 3, 1999. When it has been
consummated, we will be in a position to furnish the following report:

          "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

     High Speed Access Corp. was incorporated on April 2, 1998. No initial
capitalization transactions occurred on that date. The current Chairman of the
Board of Directors was named the sole director on formation. He also holds
significant investments in Broadband Solutions I, LLC and Broadband Solutions
II, LLC (collectively Broadband Solutions), two entities with identical
ownership.


     Broadband Solutions acquired voting control of two separate companies, High
Speed Access Network, Inc. on April 3, 1998 and CATV.net, Inc. on February 23,
1998. In each case, Broadband acquired voting control through a purchase of $500
of mandatorily redeemable convertible preferred stock of each company. Each of
these transactions was accounted for by Broadband using purchase accounting.



     On April 3, 1998, Broadband contributed its investments in CATV.net, Inc.
(CATV) and High Speed Access Network, Inc. (HSAN) (together, the "Predecessors")
to High Speed Access Corp. High Speed Access Corp. issued $1,000 in Series A
mandatorily redeemable convertible preferred stock to Broadband in exchange.
This transaction was accounted for as a transaction by entities under common
control. The Company assumed Broadband's interest in the assets and liabilities
of CATV and HSAN and recorded them at Broadband's historical cost.



     Later on April 3, 1998, the Company issued 6,200,000 shares of common stock
for all of the outstanding common stock of HSAN and CATV. The Company valued the
common stock issued in the acquisition of the Predecessors at approximately $.52
per share. In connection with the purchase of CATV, the Company issued 93,000
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 of the common
stock of CATV and HSAN have been accounted for as purchases. The accompanying
statement of operations includes the results of the Predecessors subsequent to
April 3, 1998.

2. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Principles of Consolidation

     The consolidated financial statements for the periods ended December 31,
1998 and March 31, 1999 include the operations of the Company for the period
from April 3 (inception) through December 31, 1998 and the three months ended
March 31, 1999, respectively. All significant intercompany transactions and
balances have been eliminated in consolidation.

  Interim Financial Information

     The interim financial information as of March 31, 1999 and for the three
months then ended is unaudited but includes all adjustments, consisting only of
normal recurring adjustments, that the Company considers necessary for a fair
presentation of its financial position at such date and its results of
operations and cash flows for the period. The financial and other data disclosed
in these notes to the financial statements for this period are also unaudited.
Operating results for the three months ended March 31, 1999 are not necessarily
indicative of results that may be expected for any future periods.

  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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)


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 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).

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)


  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
and March 31, 1999 (unaudited), 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 $902 as of March 31,
1999 (unaudited) and a conversion price of $12 per share. 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

                                      F-10
<PAGE>   91
                    HIGH SPEED ACCESS CORP. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)


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.

     Equipment includes assets acquired under capital leases, principally
telephone equipment, of $282 at December 31, 1998 and $365 at March 31, 1999
(unaudited). Accumulated depreciation of these assets was $34 at December 31,
1998 and $48 at March 31, 1999 (unaudited). Total depreciation expense was $696
for the period ended December 31, 1998 and $658 for three months ended March 31,
1999 (unaudited).

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.

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.

     The Company's income tax provision (benefit) for the period ended December
31, 1998 differs from the income tax benefit determined by applying the U.S.
federal statutory rate to the net loss as follows:

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.

7. MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK

</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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)


  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.

  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 and
$276 as of December 31, 1998 and March 31, 1999 (unaudited), respectively, on
Series A and $195 and $626 on Series B as of December 31, 1998 and March 31,
1999 (unaudited), respectively. In addition, the Company charged $120,282 to its
accumulated deficit during 1998 to increase the carrying value of the Preferred
Stock to its estimated redemption value at December 31, 1998 of $9.41 per share
for Series A and $10.22 per share for Series B Preferred Stock. For the three
months ended March 31, 1999 (unaudited), the Company charged $105,232 to its
accumulated deficit to increase the carrying value of the Preferred Stock to its
estimated redemption value at March 31, 1999 of $17.00 per share for both Series
A and Series B Preferred Stock.

  Conversion

     Each Series of Preferred Stock is convertible at the option of the holder
into 1.55 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

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)


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 an 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 were met. Vulcan also obtained the option to
acquire 2,500,000 additional shares of Series C Preferred Stock at $5 per share.
The Company valued this option to purchase Series C Preferred Stock at $1,000
using an accepted option pricing model and based on assumptions of a $2.50 stock
price, $5 per share exercise price, 90% stock volatility, an expected term of
approximately 12 months, zero dividend rate and 5% interest rate. The $1,000
option was recognized as an addition to paid-in capital and a reduction to the
net proceeds of the issuance of Series B preferred stock. The commitment to
issue the Series C Preferred shares to Vulcan expires on November 25, 2000.


     As further described in Note 14, Vulcan subsequently purchased the
5,000,000 shares of Series C Preferred Stock.

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)



     In November 1998, the Company entered into a systems access and investment
agreement with Vulcan and its affiliate 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 will receive the
warrants described in the following paragraph as an 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 the
Company fails to meet performance benchmarks relating to various equipment
maintenance, operations and reporting obligations 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, Web 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 Charter that will, in the
aggregate, entitle Charter to purchase 7,750,000 shares of the Company's common
stock at a purchase price of $3.23 per share. The warrants become exercisable at
the rate of 1.55 shares of common stock for each home passed in excess of
750,000. A minimum of 3,875,000 warrants must be earned by Charter on or before
July 31, 2001, and a minimum of 3,875,000 warrants must be earned by Charter on
or before July 31, 2003. Each warrant issued to Charter must be exercised on or
before one year from the date that the warrants may be earned. The warrants may
be forfeited in certain circumstances, generally if the number of homes passed
in committed systems is reduced. As of March 31, 1999 (unaudited), the Company
had issued no warrants to purchase shares of common stock to Charter.

     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 No. 96-18,
Accounting for Equity Instruments that are Issued to other than Employees for
Acquiring or in Conjunction with Selling, Goods or Services.

9. STOCK OPTION PLAN

     In April 1998, the Company's Board of Directors adopted the 1998 Stock
Option Plan (the 1998 Plan). A total of 1,395,000 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 an 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 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 $.65 and $1.61 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
$3.23 December were later determined to be compensatory based on a revised
estimate of the fair value of the Company's common stock 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 IPO occurs. Expense recognized in 1998 was
insignificant.

     Options to acquire an additional 140,740 shares under the 1998 Plan were
granted in January 1999. These options were also considered compensatory, and
the Company recorded deferred compensation of approximately $1,090 during the
three months ended March 31, 1999 (unaudited). Recognition of this expense will
also be over a five period, unless accelerated by a change in control or an IPO
occurs.

     The Company adopted the 1999 Stock Option Plan and the 1999 Non-Employee
Directors Plan (the Directors Plan) in January 1999. Under the 1999 Stock Option
Plan, 3,100,000 shares are reserved for issuances. Options to purchase 46,500
shares were granted with an exercise price of $3.23 per share. These stock
options were considered to be compensatory, and accordingly, the Company
recorded deferred compensation of $360. The Company will recognize this amount
over the five year vesting period of these options. Options to purchase 21,000
shares were also granted with an exercise price equal to the greater of $6.45 or
the IPO price per share. None of the options under this plan are currently
exercisable.

     Under the 1999 Directors Plan, options to purchase 189,875 shares with an
exercise price of $3.23 per share, all of which were immediately exercisable,
were granted in January 1999. The Company recognized expense of $1,470 during
the three months ended March 31, 1999 (unaudited) related to the issuance of
these options. Under the 1999 Directors Plan, 465,000 shares are reserved for
issuances.

     The Company has adopted the disclosure only provisions of SFAS 123. The
weighted average fair value of stock options granted was $.42 and $8.14 for the
periods ended December 31, 1998 and March 31, 1999 (unaudited), respectively.
Had compensation expense been recognized pursuant to SFAS 123, the Company's net
loss would have been increased to the pro forma amounts indicated below for the
periods ended December 31, 1998 and March 31, 1999:

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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)


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.

     Under the Company's Certificate of Incorporation, each share of outstanding
Preferred Stock will convert into 1.55 shares of Common Stock 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:

     Options and issued warrants to purchase 704,785 and 1,109,700 shares of
common stock at December 31, 1998 and March 31, 1998 (unaudited), respectively,
were excluded from the calculation above because they are antidilutive.

     On April 30, 1999 the Company issued 5,000,000 shares of Series C Preferred
Stock. If these shares had been outstanding at December 31, 1998 or March 31,
1999, it would have materially impacted the number of potential common shares
outstanding at the end of the periods.

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 for the period
ended December 31, 1998.

  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.

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 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

                                      F-21
<PAGE>   102
                    HIGH SPEED ACCESS CORP. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)


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 Company has subsequently authorized the sale of $18,500
of common stock to Cisco Systems, Inc., Com 21, Inc. and Microsoft Corporation
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, which had a net book value of approximately $330, in
exchange for 100% of the outstanding Darwin common stock. These assets consisted
primarily of computer equipment and furniture and fixtures. On March 31, 1999,
the Company distributed all of the outstanding Darwin common stock to the
Company's common and preferred stockholders. This distribution has been recorded
as a net reduction of stockholders equity in the March 31, 1999 (unaudited)
financial statements. 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 services agreement is 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 issued
to the Company a warrant to purchase 1,000,000 shares of Darwin common stock at
an exercise price of $5.00 per share, which the Company has valued at $7.
Expenses related to the Darwin service line approximated $175 in 1998 and $302
for the three months ended March 31, 1999. No revenue was realized in 1998 or
1999 associated with Darwin.

  Debt

     In April 1999, the Company entered into a $3,000 master loan and security
facility. Each advance under the agreement is to be repaid over 36 months. As of
April 30, 1999, $1.7 million had been drawn under the facility. The loan is
collateralized by certain assets of the Company.

  Series C Preferred Stock


     On April 30, 1999, the Company received $25 million in cash proceeds from
the sale of 5,000,000 shares of Series C Preferred Stock to Vulcan under the
terms of the agreements further described in Note 8.

  Road Runner Letter of Intent

     The Company signed a non-binding letter of intent in April 1999 with
ServiceCo LLC, the entity that provides Road Runner's cable internet access and
content aggregation services. Under any definitive agreement that the Company
may sign, based on the letter of intent, the Company would grant ServiceCo LLC a
warrant to purchase one share of common stock at a price of $5 per share for
each home, up to a maximum of 5 million homes, that the Company and ServiceCo
LLC designate to receive their joint services.

     In April 1999, the Company granted Microsoft a warrant to purchase 250,000
shares of common stock at an exercise price of 125% of the IPO price. Microsoft
has agreed to introduce the benefits of the Company's services to Comcast Corp.,
a multiple system cable operator. The warrant also provides Microsoft the right
to purchase one additional share of common stock for each 10 additional homes
over 2.5 million that are committed by Comcast to the Company by May 1, 2002.


     The Company estimates that it will record a charge to earnings upon the
effective date of the IPO related to the issuance of the 250,000 warrants of
approximately $1.7 million, based on a $12 IPO price. Should the Company's IPO
price be different than $12, the amount expensed related to these warrants could
be materially different. Additional expense may also be recognized in future
periods should Microsoft earn the right to purchase additional common shares
based on the number of homes committed to the Company by Comcast.


  Recapitalization

     In May 1999, the Company expects to complete a 1.55 for 1 split of its
common stock. This stock split will result in a corresponding change in the
conversion rate for all shares of the Company's redeemable convertible preferred
stock such that each share of Preferred Stock will be convertible into 1.55
shares of common stock. All outstanding warrants, if earned, may be exercised to
acquire 1.55 shares of common stock after the contemplated split. The
accompanying financial statements have been restated for all periods presented
to reflect the effects of the stock split.

     Also, the Board of Directors expects to authorize 100 million shares of
Class A common stock and increase the number of Common Stock authorized to 400
million shares. The increases in authorized shares have been reflected in the
unaudited pro forma balance sheet information as of March 31, 1999.

                         NOTES TO FINANCIAL STATEMENTS
                      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

                                      F-29

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

(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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  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:

</TABLE>

     Equipment includes amounts for assets acquired under capital leases of $41
at April 2, 1998. Accumulated amortization for these assets was $1 at April 2,
1998. Total depreciation and amortization expense for the periods ended December
31, 1997 and April 2, 1998 was $3 and $5.

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:

$1.00...................................     500,000           500             510
</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

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.

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.

                         NOTES TO FINANCIAL STATEMENTS
    FOR THE PERIODS FROM JULY 21, 1997 (INCEPTION) THROUGH DECEMBER 31, 1997
                   AND JANUARY 1, 1998 THROUGH APRIL 3, 1998
           (DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

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.

                                      F-42
<PAGE>   123
                        HIGH SPEED ACCESS NETWORK, INC.

                  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:

</TABLE>

     Total depreciation and amortization expense for the periods ended December
31, 1997 and April 2, 1998 were $33 and $30, respectively.

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.

                            HIGH SPEED ACCESS CORP.

              UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS

     The unaudited combined pro forma statement of operations for the year ended
December 31, 1998 reflects 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 follows 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.

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

1. BASIC OF PRESENTATION

     The unaudited pro forma combined statement of operations for the year ended
December 31, 1998 give effect to the acquisitions of CATV and HSAN as if they
had occurred on January 1, 1998. The effects of the acquisitions have been
presented using the purchase method of accounting and accordingly, the purchase
price was allocated to the assets acquired and liabilities assumed.

2. PRO FORMA ADJUSTMENT

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 (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
and its stockholders, 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>   134

     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 number of shares of any such series (but not below the number of shares of
such series then outstanding). The number of authorized shares of Preferred
Stock may also be increased or decreased (but not below the number of shares
thereof then outstanding) by the affirmative vote of the holders of a majority
of the stock of the Corporation entitled to vote, unless a vote of any other
holders is required pursuant to a Certificate or Certificates establishing a
series of Preferred Stock, without the necessity for a separate class vote of
the holders of the Preferred Stock.

authorized by the DGCL, as the same exists or may hereafter be amended (but, in
the case of any such amendment, only to the extent that such amendment permits
the Corporation to provide broader indemnification rights than said law
permitted the Corporation to provide prior to such amendment), against all
expense, liability and loss (including attorney's fees, judgements, fines, ERISA
excise taxes or penalties and amounts paid or to be paid in settlement)
reasonably incurred or suffered by such person in connection therewith, and such
indemnification shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of his or her heirs,
executors and administrators; provided, however, that, except as provided in
paragraph B hereof of this Article VII, the Corporation shall indemnify any such
person seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors of the Corporation. The right to
indemnification conferred in this paragraph A of this Article VII shall be a
contract right and shall include the right to be paid by the Corporation the
expenses incurred in defending any such proceeding in advance of its final
disposition; provided, however, that, if the DGCL requires, the payment of such
expenses incurred by a director or officer in his or her capacity as a director
or officer (and not in any other capacity in which service was or is rendered by
such person while a director or officer, including, without limitation, service
to an employee benefit plan) in advance of the final disposition of a
proceeding, shall be made only upon delivery to the Corporation of an
undertaking, by or on behalf of such director or officer, to repay all amounts
so advanced if it shall ultimately be determined that such director or officer
is not entitled to be indemnified under this section or otherwise. The
Corporation may, by action of its Board of Directors, provide indemnification to
employees and agents of the Corporation with the same scope and effect as the
foregoing indemnification of directors and officers.

         B. If a claim under paragraph A of this Article VII is not paid in full
by the Corporation within 30 days after a written claim has been received by the
Corporation, the claimant may, at any time thereafter, bring suit against the
Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part, the claimant shall be entitled to be paid also the expense of
prosecuting such claim. It shall be a defense to any such action (other than an
action brought to enforce a claim for expenses incurred in defending any
proceeding in advance of its final disposition where the required undertaking,
if any is required, has been tendered to the Corporation) that the claimant has
not met the standard of conduct which makes it permissible under the DGCL for
the Corporation to indemnify the claimant for the amount claimed, but the burden
of proving such defense shall be on the Corporation. Neither the failure of the
Corporation (including its Board of Directors, independent legal counsel or its
shareholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
DGCL, nor an actual determination by the Corporation (including its Board of
Directors, independent legal counsel or its shareholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

         C. The right to indemnification and the payment of expenses incurred in
defending a proceeding in advance of its final disposition conferred in this
Article VII shall not be exclusive of any other right which any person may have
or hereafter acquire under any statute, provision of the Certificate of
Incorporation, Bylaw, agreement, vote of shareholders or disinterested directors
or otherwise.

         D. The Corporation may maintain insurance, at its expense, to protect
itself and any director, officer, employee or agent of the Corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any such expense, liability or loss, whether or not the Corporation
would have the power to indemnity such person against such expense, liability or
loss under the DGCL.


                                  ARTICLE VIII

         To the fullest extent permitted by law, a director of the Corporation
shall not be personally liable to the Corporation or its shareholders for
monetary damages for any act or omission constituting a breach of his or her
duty as a director. Any repeal or modification of this Article VIII by the
shareholders of the Corporation shall not adversely affect any right or
protection of a director of the Corporation hereunder in respect of any act or
omission occurring prior to the time of such repeal or modification.

                                   ARTICLE IX

         The Board of Directors of the Corporation is authorized and empowered

                            MASTER SERVICES AGREEMENT


         This is a Master Services Agreement ("Master Agreement") dated and
effective as of January 1, 1999, between:

         HIGH SPEED ACCESS CORP.
         D/B/A HSA CORP.
         1000 West Ormsby Ave., Suite 210
         Louisville, Kentucky 40210                                  ("HSAC")

                  and

         NATIONAL CABLE TELEVISION COOPERATIVE, INC.
         14809 W. 95th St.
         Lenexa, Kansas 66215                                        ("NCTC")

                                    RECITALS

         A. NCTC is a cooperative which represents the owners/operators of RF
cable television franchise(s) and related hybrid fiber-coaxial landline
distribution system(s) across the [United States] [North America] (the
"Systems") who join as members of NCTC (individually a "Member" and collectively
the "Participating Members"). NCTC wishes to facilitate the Participating
Members' opportunity to utilize the Systems for high-speed data/Internet access
by their respective cable TV subscribers.

         B. HSAC provides high-speed data/Internet access services (the "HSAC
Services," as further defined below) to its customers through various sources,
including without limitation, cable television plants and systems.

         C. HSAC and NCTC wish to enter into this Master Agreement to provide
for HSAC's provisioning of HSAC Services to Participating Member's and their
cable subscribers, and govern various aspects of the relationship between HSAC
and NCTC as provided herein.

         NOW, THEREFORE, in consideration of the premises and mutual covenants
and agreements set forth herein and other good and valuable consideration, the
mutuality, receipt and sufficiency of which are hereby acknowledged, and
intending to be legally bound hereby, the parties agree:

         1. DEFINITIONS. Unless otherwise defined herein, all capitalized terms
shall have the meaning ascribed to them in the form of Network Services
Agreement attached hereto as Exhibit A, which is incorporated herein by
reference.

         2. NETWORK SERVICES AGREEMENT; TERM.

         (a) NCTC and HSAC agree that Participating Members may, from March 1,
1999 through December 31, 2000, subject to the Clustering requirements described
below, take and offer HSAC Services by entering into an Adoption Supplement and
Network Services Agreement with HSAC (a "Network Services Agreement"), the form
of which is attached hereto as Exhibit A. NCTC and HSAC further agree to







                                       1
<PAGE>   2


enter into good faith negotiations not later than October 1, 2000 (and every two
(2) years thereafter) to renew and/or enter into a successor Master Agreement
and form of Network Services Agreement (to be effective on January 1, 2001 (and
every two (2) years thereafter) (together the "Successor Agreements").

         (b) Notwithstanding the agreement of NCTC and HSAC to renew the Master
Agreement every two (2) years, the term of each Network Services Agreement
between HSAC and a Member shall commence effective as of the date of execution
by a Member, and shall continue for a term of not less than sixty (60) months
from the agreed "Launch Date" for each Member's System (the "Initial Term"),and
expire of December 31st of the calendar year in which the 60th month falls. The
Network Services Agreement shall then renew itself effective as of January 1st
of the next calendar year for a 12-month or 24-month term that runs concurrently
with the term of any successor Master Agreement between NCTC and HSAC then in
effect (i.e., the Network Servicesrenewal may be for one or two years depending
on the cycle) unless notice of intent not to renew is sent by either Member or
HSAC to the other not less than less than 60 days or more than 120 days prior to
such December 31st expiration date. Upon any such renewal, Member shall have the
option of continuing to be governed by its original Network Services Agreement,
or the successor Network Services Agreement then in effect (except for the
length of the term as provided in the previous sentence.

         Example #1: Operator enters into a Network Services Agreement with HSAC
         with an effective date of August 1, 1999, and HSAC launches HSAC
         Services on or before November 1, 1999. The Network Services Agreement
         will expire December 31, 2004. NCTC and HSAC enter into a Successor
         Agreements and Network Services Agreement effective January 1, 2003.
         Operator shall have a 60-day option commencing September 1, 2004 to
         either (i) allow the Network Services Agreement to expire, or (ii) (a)
         renew the Network Services Agreement then in effect with HSAC or adopt
         the terms and conditions of the successor Network Services Agreement
         for a period commencing January 1, 2005, and expiring on December 31,
         2005.

         Example #2: Operator enters into a Network Services Agreement with HSAC
         with an effective date of August 1, 2000, and HSAC launches HSAC
         Services on or before November 1, 2000. The Network Services Agreement
         will expire December 31, 2005. NCTC and HSAC enter into a Successor
         Agreements and Network Services Agreement effective January 1, 2005.
         Operator shall have a 60-day option commencing September 1, 2005 to
         either (i) allow the Network Services Agreement to expire, or (ii)
         renew the Network Services Agreement then in effect with HSAC or adopt
         the terms and conditions of the successor Network Services Agreement
         for a period commencing January 1, 2005, and expiring on December 31,
         2007.

         3. CLUSTERING. HSAC shall not be required to individually provision
HSAC Services to, and instead shall enjoy complete discretion to "cluster," the
Systems of Participating Members that encompass fewer than 5000 homes passed (a
"Sub-5000 System"). Us used herein or in any Network Services Agreement, a
"cluster" or "clustering" means that one or more Sub-5000 Systems may, for
purposes of aggregating the flow of data to, from and among such Sub-5000
Systems to HSAC's ISP portal or POP, be combined by HSAC with other Systems or
Sub-5000 Systems so that the clustered Sub-5000 Systems mimic the size, economic
and technical specifications of a System exceeding 10,000 homes passed. The head
ends of clustered Sub-5000 Systems must situate within a 50-mile radius of each
other either concentrically or






                                       2
<PAGE>   3


sequentially, and shall employ such data transmission technology (telco circuit,
VSAT, xDSL, etc.) as HSAC shall determine in its sole discretion.

         4. MOST FAVORABLE REVENUE SHARING. If, during the term of this
Agreement, HSAC enters into a Network Services Agreement for the provision of
HSAC Services to a Participating Member with an equal or fewer number of Data
Subscribers than the then-aggregate number of Participating Members' Data
Subscribers under which HSAC pays a higher percentage of Gross Revenues or Net
Gross Revenues, as the case may be, or offers cash or other equivalent
consideration (not including equity incentives) not offered to other
Participating Members under their Network Services Agreement, then HSAC shall
promptly notify NCTC of such agreement, whereupon HSAC, at the election of NCTC
and the Operator, shall pay such higher percentage or offer equivalent
consideration (not including equity incentives) to other Participating Members
as are provided in such Participating Member's agreement; provided that such
Participating Member shall be subject to and in compliance with all applicable
terms and conditions of the agreement.

         5. MOST FAVORED CONTRACT; EXTENDED TERM. HSAC agrees that during the
term of this Agreement that a Participating Member shall have the option of
simultaneously terminating any pre-existing network services agreement with HSAC
and adopting HSAC Services as a "Participating Member" under the Network
Services Agreement provided for herein except that Operator in so doing shall be
deemed to adopted a new term of agreement as set forth in Section 2(b) hereof.

         6. NCTC ADMINISTRATION SERVICES; FEE.

                  (a) During the term hereof, NCTC shall perform the following
services for HSAC and the Participating Members (the "Administration Services"):

     i.   Communication of and endorsement of HSAC Services to Participating
          Members;

     ii.  Tracking and notification of Participating Members with respect to
          expiration of Network Services Agreements and options with respect to
          election of Successor Agreements;

     iii. Collection, review, handling and processing of Adoption Certificates
          and Network Services Agreements; and

     iv.  Annual audit of HSAC reports/monthly payments to Participating Members
          (Section E.4 of the Network Services Agreement).

                  (b) NCTC may at its option elect to collect HSA's Share (as
defined in Exhibit E to the Network Services Agreement) from Participating
Members serving a billing party under Exhibit E/Section E.3.1 of the Network
Services Agreement and remit same to HSAC within 45 days in accordance with the
procedure/schedule set forth therein.

                  (c) HSAC shall pay to NCTC annually during the term hereof, on
or before January 31, a fee (calculated as of December 31 of the prior year)
equal to 1% of the Participating Members' share of the aggregate Gross Revenues
and Net Gross Revenues collected from Data Subscribers for the prior calendar
year.

Requirements during the period of time of this Agreement. In the event Operator
refuses to effect appropriate Attainment Measures, this Agreement shall
terminate without liability of any kind to Operator or HSAC. EXHIBIT B may set
forth the time frame agreed upon by Operator and HSAC for the Operator to bring
the System into conformity with the System Data Requirements.

                        (c) At such time as Operator and HSAC agree that the
System is sound and meets the System Data Requirements, and subject to HSAC's
right to defer and Cluster Sub-5000 Systems for deployment, HSAC and Operator
will agree within 30 days upon a timetable to "commission" the System, and HSAC
shall launch the HSAC Services to Data Subscribers within 180 days thereafter,
as follows:


     i.   install and connect the HSAC Network Equipment (Operator will provide
          a reasonable amount of collaction/rack space, physical security,
          AC/climate control and electrical power supply for the HSAC Network
          Equipment);

     ii.  arrange at HSAC's expense for data transport (via telco, wireless,
          etc.) from the Internet to the Operator's head-end(s)/System;

     iii. arrange telco return path circuits in one-way Systems;

     iv.  test the HSA Network Equipment interface;

     v.   activate the data through-put portion of the HSAC Services, initiate
          beta testing with a select group of complimentary "beta" customers;
          and

                        (c) The HSAC Network Equipment will at all times be the
property of HSAC, and will be insured by HSAC against casualty loss. Upon
termination of this Agreement (unless purchased by Operator pursuant to Section
5 hereof), Operator agrees to make available for recovery by HSAC all HSAC
Network Equipment, subject to reasonable wear and tear. HSAC will not damage or
disable the System head-end while recovering the HSAC Equipment, and will leave
the System functional (except for termination of HSAC Services). Operator will
use reasonable care to avoid damaging or disconnecting the HSAC Network
Equipment, and will not move, relocate, alter, sell, lease, license, assign,
encumber or otherwise tamper with the HSAC Network Equipment, and will pay to
repair or replace HSA Network Equipment that Operator or its employees damage.

                  3.3 Home Equipment Package. HSAC will select the vendor/brand
of cable Home Equipment Packages, and then procure, rent to*, and arrange for
the installation by the Data Subscriber, Operator, or other authorized
resellers/installers of, the Home Equipment Package for each Data Subscriber.
(*Unless purchased directly at retail by the Data Subscriber, HSAC shall retain
ownership of the Home Equipment Package, and Data Subscriber will be required to
sign a statement acknowledging such ownership).

                  3.4 Allocation of Operational Responsibilities. Upon
activation of the HSAC Services, HSAC will have the exclusive right to
manage/monitor the data that flows through the HSA Network
Equipment/data-switched portion of the System. Neither HSAC nor Operator shall
be responsible for third-party software.

                  3.5 Notice of Service Failures. Operator and HSAC each agree
to notify the other's Designated Personnel promptly of any outages,
interruptions or degradation of service in either the RF plant portion 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 will provide technical personnel within 6 hours or less (or
as soon as commercially practicable) to repair and/or respond to such Service
Failure and restore the HSAC Services. To the extent the Service Failure is
traceable to HSAC Network Equipment or a data stream malfunction (whether or not
due to force majeure), HSAC will likewise correct the Service Failure within 6
hours or provide technical personnel within 24 hours (or as soon as commercially
practicable) to repair or replace any malfunctioning HSAC Network Equipment. In
no event however does HSAC warrant to Operator, or Operator warrant to HSAC,
that their respective systems and services (i.e., the System, the HSAC Services,
the HSA Network Equipment, or the Internet ISP access portal/data stream
afforded by and through the ISP or other utilities will be uninterrupted,
error-free or secure from criminal intrusion (i.e., by "hackers").

work together diligently to respond to all Service Failures, and shall
coordinate the scheduling of maintenance that might interfere with the HSAC
Services. Both parties agree and acknowledge that downtime, incorrect or
inaccurate Data Subscriber invoicing, and infrastructure problems will be given
highest priority attention at all times. Operator and HSAC shall each have
access to the other's Designated Personnel (EXHIBITS F and G) on a 24x7 basis
(including weekends and holidays) via pager, cell phone or similar means for the
purpose of troubleshooting Service Failures pursuant to agreed-upon Escalation
Procedures, which may be annexed hereto as EXHIBIT C.

                  3.7 Customer Service. HSAC shall provide a toll-free telephone
number and telephone support representatives to take customer service calls from
Data Subscribers regarding Service Failures and the performance of the Home
Equipment Package, and the Internet browser and electronic mail software
provided by third parties. Operator shall also provide its Data Subscribers with
a "customer service response" service for the System/RF portion of the HSA Data
Network. HSAC shall make its engineers and technicians available as needed on a
second-level basis to provide technical support and to serve as liaisons between
or among the Data Subscribers, Operator, and HSAC. Except in the case of a
Service Failure requiring immediate notification under Section 3.5 above, HSAC
will inform Operator of any System/RF Plant problems of which HSAC becomes aware
(i.e., RF level, hum, etc.) as soon as commercially practicable.

                  3.8 Billing of Data Subscribers; Internet Usage. The
processing of subscriptions for HSAC Services from Data Subscribers and the
invoicing of Data Subscribers shall be handled as set forth on EXHIBIT E hereto
and incorporated herein by reference. Additionally, HSAC shall distribute to and
require Data Subscribers to sign an "Internet End User/Services Agreement" (the
"End User Agreement") which describes the limits placed on Data Subscribers
rights to damages and indemnification. HSAC shall have the right but not the
obligation to enforce the terms and conditions of the End User Agreement and/or
reprice or terminate a Data Subscriber's account for violations of the End User
Agreement.

                  3.9 Data Subscriber Cancellation/Disconnect. In the event a
Data Subscriber terminates all of his, her or its cable TV/RF services with
Operator, Operator will notify HSAC and use commercially reasonable efforts to
recover and store the Home Equipment Package (except for any NIC/ethernet card
inside the customer's computer) for HSAC at no charge. In the event a Data
Subscriber cancels only his, her or its subscription to HSAC Services, HSAC
shall be responsible for recovering the Home Equipment Package.

                  3.10 Promotional and Build-Out Activities.

         (a) The parties will cooperate reasonably with one another regarding
the marketing and promotion of HSAC Services to Operator's Cable Subscribers
with the aim of maximizing the number of Data Subscribers. Such cooperation will
include (i) a "drop/install" at Operator's expense to any home passed in the
System, and (ii) Operator's distribution of marketing to Cable

Subscribers regarding the HSAC Services (e.g., a reasonable number of
complimentary "ad avails" on Operator's cable TV system on and with appropriate
channels, times, durations, and demographics, space in bills, statement
messaging, space in installation packs, POP displays, etc.), provided that HSAC
will reimburse Operator for the incremental postage associated with bill
stuffers. Each party will nominate at least one (1) employee each to meet and
jointly review marketing plans and materials assure acceptable quality
standards. Operator will not delete or alter, or authorize the deletion or
alteration of, any copyright or trademark notice, logo, credit or any other
notice included in any promotional materials delivered pursuant to this
paragraph.

         (b) Operator will provide HSAC access (both print copy and
electronically) to its Customer List(s) on a confidential basis solely for the
purpose of developing and implementing a marketing plan, developing and
implementing a billing system for Data Subscribers, and otherwise provide
"OnLine Help-Desk" modem configuration support, Data Subscriber sign-up, and
ongoing customer service.

         (c) The parties further agree to jointly review and evaluate
periodically the economic feasibility of expanding (i.e., into a central
business district, university campus, etc.) or upgrading Operator's RF Plant in
the System in order to increase the number of homes passed and/or commercial
Data Subscribers.

                  3.11 Complimentary Accounts. HSAC will at Operator's direction
provide to Homes Passed in the System complimentary HSAC Services accounts
(except that such recipients of complimentary service must pay for their own
Home Equipment Packages as would any other Data Subscriber) as follows:

     a)   up to five (5) non-transferable accounts as designated by Operator;

     b)   a reasonable number of other government/"community service" accounts;

     c)   a reasonable number of accounts for Operator's office(s) (via multiple
          modems or single-modem with hub/proxy server distribution as the
          parties may agree) within the System, and Operator's employees at
          their residences; and

     d)   such other complimentary accounts as HSAC in its sole discretion shall
          determine.

These accounts may only be used by the parties to be listed on EXHIBIT D and may
not be transferred by Operator or the parties listed without the written consent
of HSAC.

                  3.12 Advertising Expenditures; In-System Marketing Personnel.
HSAC agrees to commit advertising funds in an amount not less than $1.50 per
Home Passed in connection in the initial Launch Date, and at least $.25/Home
Passed annually in such System thereafter. In addition, with respect to Systems
encompassing 10,000 or more homes passed, HSAC will hire or retain one (1)
"local" marketing manager/firm to coordinate the initial launch of HSAC Services
and follow-on Data Subscriber-end user sales and installation activities in the
System. In Systems encompassing fewer than 10,000 homes passed and
Clustered/Sub-5000 Systems, HSAC will engage or retain a "regional" manager/firm
for the System and other Systems in the






                                       9
<PAGE>   14

area (which may or may not be Systems owned by Participating Members) for the
purpose of coordinating and supervising the marketing of HSA Services to Data
Subscribers.

         4. Miscellaneous Matters Regarding Branding, Optional Services;
Content, Other Matters.

                  4.1 Branding. HSAC will brand, market, deploy and support the
HSAC Services in the System under the Operator's tradenames (with Operator's
reasonable consent) or such other brands/service marks or co-brands as HSAC and
Operator may jointly designate. HSAC is accordingly granted a license to use
Operator's name and logo to brand the HSAC Services and create HSAC Local
Content, which shall include, advertising, opening web pages, billing, etc. HSAC
will produce and distribute all marketing materials and execute all marketing
plans applicable to the HSAC Services.

                  4.2 Exclusivity; Limits on Overbuilding/Competition. HSAC will
enjoy exclusive rights under this Agreement to provide HSAC Services (and
non-Gross Revenue generating enhancements to those HSAC Services) in the System.
This includes the rights to market, invoice, and retain its share of Gross
Revenues on accounts enrolled by HSAC on homes passed and business/commercial
subscribers (whether connected by coax or fiber) regardless of whether the
Operator is competing in the System area as a CLEC (i.e., a tariffed Competitive
Local Exchange Carrier), CAP (i.e., a Competitive Access Provider), or other
form of carrier or telco contractor. Except as provided in Section 4.5 below in
connection with "dial-up" services, HSAC will not deploy HSAC Services under an
agreement with or in conjuction with another MSO-cable operator/overbuilder
within the System. Moreover, HSAC may in its discretion refuse to accept any
Adoption Supplement or deploy HSAC Services in connection with any Operator's
overbuild activities.

                  4.3 Content. HSAC shall designate and prescribe the Data
Subscriber's initial start page and the content thereof. HSAC will also create
and distribute HSAC Local Content linked to such initial start page. Prior
distributing such HSAC Local Content, HSAC will furnish same to Operator,
whereupon Operator shall have ten (10) days to review and offer comments and
suggestions to HSAC regarding such content. HSAC shall not be obligated to
accept any such suggestions from Operator, and Operator shall no right to
disapprove or block the distribution of such HSAC Local Content unless such HSAC
Local Content is manifestly deragatory or dilutive to Operator's brand or
tradenames/trademarks. The "Gross Profits" (i.e., gross sales less direct
operating costs) of captured advertising, E-commerce and any other ancillary
revenues generated by HSAC's or Operator's efforts specifically for and included
within the HSAC Local Content will be deemed Gross Revenues for purposes of
calculating the Operator's Share as set forth in Exhibit E.

                  4.4 Optional Services. HSAC may upon notice to and consent of
the Operator (such consent not to be unreasonably withheld provided HSAC offers
such Optional Services on a competitively-priced basis) develop and deploy Gross
Revenue-generating Optional Services through








                                       10
<PAGE>   15


the HSA Network Equipment for Data Subscribers and invoice for same. If HSAC
deploys IP telephony or other Optional Service, HSAC shall pay Operator a
percentage of the "Gross Profits" (defined in the previous subparagraph)
generated from the sales/distribution of such services as set forth on Exhibit
E. Optional Services may or may not be branded under the Operator's logos and
service marks as the parties agree.

                  4.5 Additional Connectivity Services. HSAC will have the right
to market and deploy broadband connectivity services (via analog or xDSL modem,
wireless/transciever, etc. broadband technology) to "dial-up" residential and
commercial customers both within and outside the System area that do not qualify
as homes passed/Cable Subscribers and do not utilize the Operator's RF
plant/head-end equipment or the HSA Network Equipment. HSAC will pay 15% of the
"Net Revenues" (i.e., gross revenues less any splits, leased line or other
access fees, or other payments paid to the owner of the copper or other
non-hybrid-fiber/coaxial network owner (be it an RBOC, other telco, or
proprietary LAN owner such as a university, etc.) for access to its bandwidth)
generated from such "dial-up" services to Operator. Such "dial up" customers
will be deemed "owned" by HSAC for purposes of this Agreement. HSAC will retain
such "dial up" customers and 100% of the Gross Revenues generated from "dial-up"
services in the event of any termination or expiration of this Agreement;
provided, that if the Operator expands/upgrades its System/RF plant such that
HSAC's "dial-up" customers eventually qualify as homes passed or Cable
Subscribers, HSAC will make commercially reasonable efforts to enroll such
customers as Data Subscribers.

                  4.6 Security. HSAC may at its option make available security
and encryption equipment and software to Data Subscribers at no additional
charge to Operator; provided, that HSAC is not obligated to do so, nor shall it
be liable or responsible in any way for the installation and performance of such
equipment or software.

         5. Term of Agreement; Expiration; Termination Fee.

                  5.1 Term; Renewal. This term of this Agreement shall commence
effective as of the date set HSAC accepts and countersigns the Operator's
Adoption Supplement, and shall continue for a term of not less than sixty (60)
months from the agreed "Launch Date" for each Member's System ,and expire on
December 31st of the calendar year in which the 60th month falls (the "Initial
Term"). The Network Services Agreement shall then renew itself effective as of
January 1st of the next calendar year for a 12-month or 24-month term that runs
concurrently with the term of any successor Master Agreement between NCTC and
HSAC then in effect (i.e., the renewal of this Network Services Agreement may be
for one or two years depending on the cycle) unless notice of intent not to
renew is sent by either Member or HSAC to the other not less than less than 60
days or more than 120 days prior to such December 31st expiration date. Upon any
such renewal, Member shall have the option of continuing to be governed by this
Network Services Agreement, or any successor Network Services Agreement then in
effect (except for the length of the term as provided in the previous sentence).

<PAGE>   16

         Example #1: Operator enters into a Network Services Agreement with HSAC
         with an effective date of August 1, 1999, and HSAC launches HSAC
         Services on or before November 1, 1999. The Network Services Agreement
         will expire December 31, 2004. NCTC and HSAC agree upon a successor
         form of Network Services Agreement effective January 1, 2003. Operator
         shall have a 60-day option commencing September 1, 2004 to either (i)
         allow the Network Services Agreement to expire, or (ii) renew the
         Network Services Agreement then in effect with HSAC or adopt the terms
         and conditions of the successor Network Services Agreement for a period
         commencing January 1, 2005, and expiring on December 31, 2005.

         Example #2: Operator enters into a Network Services Agreement with HSAC
         with an effective date of August 1, 2000, and HSAC launches HSAC
         Services on or before November 1, 2000. The Network Services Agreement
         will expire December 31, 2005. NCTC and HSAC enter into a Successor
         Agreements and Network Services Agreement effective January 1, 2005.
         Operator shall have a 60-day option commencing September 1, 2005 to
         either (i) allow the Network Services Agreement to expire, or (ii)
         renew the Network Services Agreement then in effect with HSAC or adopt
         the terms and conditions of the successor Network Services Agreement
         for a period commencing January 1, 2005, and expiring on December 31,
         2007.

                  5.2 Termination. This Agreement may be terminated as follows:

         (a) At Operator's option exercised on sixty (60) days written notice to
HSAC, in which event Operator shall:

                  (i) purchase (or assume the leases) from HSAC at book value
         the HSAC Equipment and Home Equipment Packages committed to Operator's
         System, or, make available to HSAC all HSAC Network Equipment in good
         condition, normal wear and tear excepted, and exercise its commercially
         reasonable best efforts to assist HSAC with recovery of all Home
         Equipment Packages owned/leased by HSAC from Data Subscribers; AND

                  (ii) pay to HSAC a Termination Fee, i.e., an amount equal to
         the net present value of the Gross Revenues for HSAC Services which
         would otherwise have been generated from HSAC's then-existing base of
         Data Subscribers in the System, which in any event shall not be less
         than the amount required to fully reimburse HSAC for any unrecovered
         direct "up-front" capital, marketing, and operating costs incurred in
         deploying the HSAC Services in the System. If Operator and HSAC cannot
         agree upon the amount of any Termination Fee, they shall jointly engage
         and split the cost of a neutral appraiser/valuation specialist to place
         a value on such Termination Fee.

         (b) At HSAC's option exercised on sixty (60) days written notice to
Operator, in which event HSAC shall be liable for damages as if Operator had
terminated this Agreement because of breach by HSAC (subject to the limitations
in Section 12).




                                       12
<PAGE>   17

         (c) By either party upon breach by the other as provided in Section 13,
in which event the defaulting party shall be liable for damages for breach
(subject to the limitations in Section 12).

         (d) By Operator, without further liability of either Operator or HSAC,
if: (i) Operator and HSAC have not agreed upon a timetable for launch within the
30 day period provided under Section 3.1 (c); (ii) the HSAC Services have not
been launched by the later of the agreed upon launch date or 180 days from the
date the parties agreed upon the timetable; or (iii) HSAC has refused to deploy
HSAC Services under the last sentence of Section 4.2.

         6. Fees for Services. HSAC will invoice Data Subscribers and pay to
Operator the Operator's Share of Gross Revenues, Gross Profits and Net Gross
Revenues as set forth on EXHIBIT E attached hereto.

         7. Designated Operator Personnel. Operator shall identify by name and
location all Operator Designated Personnel required in Section 3. The personnel
identified shall have authority to authorize an investigation of Service
Failures in the RF portion of the Network and have knowledge of pertinent
maintenance, repair and support procedures. The list of authorized Operator
contact personnel is set forth in EXHIBIT F of this Agreement, provided that
such list may be revised by Operator at any time as long as HSAC is informed in
writing and such list includes at least three (3) Operator contact personnel.

         8. Designated HSAC Personnel. HSAC shall identify by name and location
all HSAC Designated Personnel required in Section 3. The personnel identified
shall have authority to authorize an investigation of Service Failures in the
data portion of the HSA Data Network and have knowledge of pertinent
maintenance, repair and support procedures. The list of authorized HSAC contact
personnel is set forth in EXHIBIT G of this Agreement, provided that such list
may be revised by HSAC at any time as long as Operator is informed in writing
and such list includes at least three (3) HSAC contact personnel.

         9. Confidential Information.

                  9.1. Each party agrees that it shall not, during or 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 (a) not disclose any Confidential Information to any third person without
the express written consent of the disclosing party; (b) 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; (c) 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







                                       13
<PAGE>   18


Confidential Information, all such copies shall bear the same confidentiality
notices, legends, and intellectual property rights designations that appear in
the original versions.

                  9.2. Apart from HSAC's obligations to Operator under this
section concerning confidentiality, HSAC shall have no obligation to delete or
destroy Operator's information, including Operator's Cable or 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 all expenses associated with the
early deletion or destruction of all such data.

                  9.3. Operator acknowledges that the names and marks "HSA",
"HSAC", "HSA Network", "High Speed Access Network", the "HSA Data Network" 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 HSA Service, are the exclusive property of
HSAC. Operator has not and will not acquire any proprietary rights thereto by
reason of the 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. Conversely, HSAC acknowledges that the
Operator's logos, trademarks, service marks, programs, manuals, documentation,
and other support materials covered by this Agreement or otherwise used in
connection with the HSAC Services, are the exclusive property of Operator. HSAC
has not and will not acquire any proprietary rights thereto by reason of the
Agreement, 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.

         10. Reproduction of Manuals and Documentation. Subject to the
provisions of Section 9, 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 or is requested to be affixed by HSAC.

         11. Indemnity.

                  11.1 HSAC agrees to indemnify and save harmless Operator, and
Operator agrees to indemnify and save harmless HSAC, from any liabilities,
lawsuits, penalties, claims, or demands finally awarded or settled (including
the costs, expenses, and reasonable attorneys' fees on account thereof) that may
be made by any third party 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. HSAC
agrees to defend Operator, at Operator's







                                       14
<PAGE>   19


request, and Operator agrees to defend HSAC, at HSAC's request, against any such
liability, claim, or demand. Operator and HSAC respectively agree to notify the
other party promptly of any written claims or demands against the indemnified
party for which the indemnifying party is deemed responsible hereunder.

                  11.2 HSAC agrees to indemnify and save harmless Operator from
all Third Party Threats (defined in Section 12 below) and claims arising as a
direct result of HSAC's management, operation and control of the HSAC Services.

         12. Limitation of Liability and Disclaimer of Warranty.

                  12.1. In no event shall HSAC or Operator be liable to one
another for (a) any special, indirect, incidental, punitive, or consequential
damages, including loss of profits arising from or related to the breach of this
Agreement, even if HSAC or Operator had been advised of the possibility of such
damages; (b) damages (regardless of their nature) arising from any Third Party
Threats (defined below) for any delay or failure by HSAC or Operator to perform
its obligations under this Agreement due to any cause beyond their respective
reasonable control; or (c) claims made a subject of a legal proceeding against
HSAC or Operator more than twenty-four (24) months after any such cause of
action first arose. HSAC and Operator specifically acknowledge and agree to the
limitations on their respective liability to Data Subscribers as they relate to
issues of lack of privacy and security, the possibility of viruses, offensive
content, loss/theft of passwords, unauthorized access by hackers, etc. (i.e.,
"Third Party Threats"), as set forth in the End User Agreement (a copy which may
be attached hereto as EXHIBIT H). HSAC and Operator further agree that all such
liability limitations apply to Operator and its software systems and System as
well. Operator and HSAC hereby waive the assertion of any claims relating to,
and release each other from any liability for, any and all claims associated
with or related to such Third Party Threats. Operator and HSAC agree to exercise
their best 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. HSAC will maintain appropriate
policies of general liability, casualty and workers compensation insurance to
cover HSAC's employees against injury to themselves or others and casualty
accidents while working on Operator's premises/System. All such HSAC policies
shall name Operator as an additional insured to the extent HSAC may legally do
so. Operator shall furnish HSAC with a list of its System offices and head-ends
for HSAC's insurance brokers.

                  12.2 HSAC'S AND OPERATOR'S LIABILITIES TO ONE ANOTHER UNDER
THIS AGREEMENT (WITH THE EXCEPTION OF OPERATOR'S LIABILITY TO HSAC FOR ANY
TERMINATION FEE UNDER SECTION 5.2(ii)), WHETHER UNDER CONTRACT LAW, TORT LAW, OR
OTHERWISE, SHALL BE LIMITED TO THE LESSER OF (a) THE AVERAGE MONTHLY OPERATOR'S
SHARE OF GROSS REVENUES (OR HSAC'S SHARE, AS THE CASE MAY BE) FOR THE MONTH IN
WHICH THE LIABILITY AROSE, OR EQUIVALENT THEREOF, FOR HSAC SERVICES PERFORMED
UNDER THIS AGREEMENT FOR THE ACTUAL NUMBER OF MONTHS DURING WHICH THE PROBLEM
EXISTED; OR (b) THE ACTUAL AMOUNT OF MONEY DAMAGES INCURRED BY OPERATOR OR HSAC.


                                       15
<PAGE>   20


                  12.3 Nothing in this Section 12 shall be interpreted to limit
the indemnity obligations of the parties set forth in Section 11 above.

         13. Default and Termination. If either party defaults in any material
respect in the performance of any of its material obligations hereunder and such
default shall not be cured within thirty (30) days after written notice thereof
from the other, or if either party becomes insolvent, or if a petition under any
bankruptcy act shall be filed by or against either party (which petition, if
filed against any affiliate of either party, shall not have been dismissed
within thirty (30) days thereafter), or if either party executes an assignment
for the benefit of creditors, or if a receiver is appointed for the assets of
either party, or if either party takes advantage of any insolvency or any like
statute (any of the above acts are hereinafter called "Event of Default"), then
the other party may at its option, in addition to any and all other rights which
party may have, declare a default and terminate this Agreement by giving written
notice to the other party within ten (10) business days from the date of the
occurrence or maturity of any Event of Default. Notwithstanding any other
provision of this Agreement, neither HSAC or Operator will be deemed in default
of this Agreement to the extent any delays in their respective performance are
reasonably and demonstrably attributable to the actions or inaction of the other
or events and circumstances outside of their reasonable control, including, but
not limited to, the actions or negligence of third party vendors. For example,
HSAC will not be deemed in default of this Agreement if (i) a Regional Bell
Operating Company ("RBOC") or other telephone network provider (a "telco") is
late in installing T-1 or other transport from a System head-end to the ISP
portal following the submission of a timely order by HSAC, or (ii) an equipment
vendor (e.g., COM21) fails to meet its delivery deadlines with respect to HSAC
Network Equipment or Home Equipment Packages.

         14. Independent Contractor. All work performed by HSAC in connection
with the HSA 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 of the contrary. Each party is acting as
principal hereunder.

         15. 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, strikes or other labor unrest, power surges, acts
or omissions of carriers/utilities, acts of God, or other similar causes or
contingencies beyond its reasonable control (i.e., a "Force Majeure"); provided,
that neither party shall relieved under this Section 15 from its obligations
under Sections 3.5 and 3.6 hereof with respect to timely repairs (i.e., thirty
(30) days or




                                       16
<PAGE>   21

less) of Service Failures caused by such Force Majeure once the condition is
removed. If any such an 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 or parties may resume performance of its duties
once the condition ceases, and the term of this Agreement shall by notice be
deemed to be extended for such affected System up to the length of time the
condition endured.

         16. Assignment. This Agreement shall be binding on the parties hereto
and their respective successors and assigns; PROVIDED, that each party hereto
shall be permitted, upon 30 days advance written notice to the other, to assign
(by assets purchase or other written agreement, merger, consolidation, sale of
assets, operation of law or otherwise) its rights, title and interest under this
Agreement to a successor entity which specifically assumes the assignor's
rights, title and interest under this Agreement prior to or contemporaneous with
the closing of such assignment. No such assignment shall relieve a party of its
obligations hereunder. All assignments in contravention of this section shall be
null and void. Both HSAC and the Operator will be permitted to collaterally
assign and grant a security interest in its contract rights and
tangible/intangible property interests (including the HSA Network Equipment and
Home Equipment Packages) arising under this Agreement for purposes of securing
financing from its commercial lenders.

         17. 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, and all such changes shall reference this Agreement and identify
the specific articles or sections of this Agreement that is amended, modified,
or supplemented.

         18. Notices. All notices, demands, or other communications herein
provided to be given or that may be given by any party to the other shall be
deemed to have been duly given when made in writing and delivered in person, or
upon receipt, if (a) deposited in the U.S. mail, postage prepaid, certified
mail, return receipt requested; or (b) sent by nationally recognized overnight
courier in a postpaid wrapper, and addressed as follows:

                                    EXHIBIT B

                            SYSTEM DATA REQUIREMENTS
                     (TECHNICAL REQUIREMENTS FOR RF PLANTS)

         A. HSAC will inspect and characterize the two-way cable plant to
determine its feasibility for digital data transmission. This characterization
will focus on the integrity of the cable plant against interference, intermod
distortions, ingress, system noise, and transient/impulse noise.

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

         C. Operator's RF/cable network must 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.

         D. A written report detailing network deficiencies and recommendations
("Attainment Measures") for improvement will be furnished to the Operator.

                          ANALOG PERFORMANCE PARAMETERS

1) 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.

2) 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.

3) 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 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.

4) 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.

5) 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






                                       22
<PAGE>   27


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 will
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 will result in
interrupted high-speed data access service to the customer.

6) 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 will
help minimize any group delay associated with the roll-up or roll-off of the
return spectrum.

7) RETURN PLANT VISUAL CARRIER-TO-NOISE RATIO (CNR) - HSAC guidelines specify a
minimum 36 dB visual CNR over the return 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.

8) 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 +/- 2dB from 0.75 MHz to 5.0 MHz should also apply to reverse video
transmission.

9) DISTORTION - HSAC expects that the level of CSO and CTB distortions on the
return path* will 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).

10) SIGNAL AVAILABILITY- HSAC in cooperation with the system partner will
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 the
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.

11) 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.

(As used herein, "HSA's Share" shall mean 1.00 minus the Operator's Share.)

                  E.2 Data Subscriber Refunds. HSAC's local management will 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. 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 repeatedly rendered inoperable or unusable due to the System
failing to meet System Data Requirements or to repeated Service Failures
traceable to the Operator's RF plant/System (and such is not corrected within
the period specified in Section 3.5 of the Agreement) other than failures caused
by a Force Majeure.


                  E.3 Billing; Sales Taxes; Franchise Fees.

                      E.3.1 Operator at its option elect to implement and
operate a billing systems and invoice Data Subscribers directly for all HSAC
Services, in which case HSAC shall invoice Operator (with a copy to NCTC)
monthly, in advance, for all HSAC Services to be provided to Data Subscribers,
by delivering to Operator a statement (a "Statement") showing the computation of
Operator's Share (derived from the total number of Data Subscribers and Gross
Revenues, Gross Profits, or Net Revenues) and corresponding HSAC Share, in
accordance with this EXHIBIT E..

                      E.3.2 Unless Operator elects to operate the billing system
for Data Subscribers, HSAC will implement and operate the billing system and
invoice Data Subscribers for all HSAC Services, in which case HSAC shall invoice
Data Subscribers monthly, in advance,




                                       26
<PAGE>   31

for all HSAC Services to be provided to Data Subscribers, and deliver to
Operator a related Statement.

                      E.3.3 Except as otherwise provided in Section 25 regarding
franchise taxes, the party electing to invoice Data Subscribers under Section
E.4.1 or E.4.2 above shall bear all risk associated with the collection and
remittance of applicable sales and use taxes and franchise taxes, provided that
HSAC will remit to the Operator for pass-through remittance by the Operator to
the franchise authority (which Operator agrees to do on a timely basis) of any
applicable franchise taxes HSAC collects from Data Subscribers.

                      E.3.4 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 for the purpose of developing and implementing
a billing system. HSAC and Operator shall work together to develop and implement
an electronic interface between HSAC and Operator for tracking and invoicing
Data Subscribers and vendors. HSAC may at its expense arrange for a data
exchange/software interface to be written and implemented which enables HSAC to
access and interface with Operator's billing system for purposes of updating on
a real-time basis both HSAC's and Operator's records regarding the status of
Data Subscriber accounts so that such accounts may be automatically managed in
the same manner that as Cable Subscriber accounts are managed.


                  E.4 Settlement; Verification.

                      E.4.1 Where Operator acts a billing party under Section
E.3.1 above, within forty-five (45) days following the end of each and every
calendar month during the term hereof, Operator shall remit a check to HSAC for
HSAC's Share.

                      E.4.2 Where HSAC acts a billing party under Section E.3.2
above, within forty-five (45) days following the end of each and every calendar
month during the term thereof, HSAC will deliver to Operator a Statement for
such month and remit a check for same.

                      E.4.3 HSAC will keep books and records relating to the
Operator's Share in accordance with generally accepted accounting principles,
consistently applied. During the term hereof and for one year thereafter,
Operator, NCTC or their authorized representatives may, at their own expense,
visit HSAC's offices during regular business hours, subject to suitable
protections relating to confidentiality and non-disclosure, to inspect and make
extracts and copies of any such books and records in order to determine the
accuracy of the Statements. If any audit of Statements undertaken by Operator or
NCTC in accordance with this Section E.3 discloses a five percent (5%) or
greater discrepancy from the Statement(s) generated by HSAC, HSAC shall pay such
amounts to the affected Operator and reimburse such Operator or NCTC for all
costs incurred by Operator in connection with such audit.
