              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


                         SEPTEMBER 30, 2000 (UNAUDITED)


1.   ORGANIZATION AND NATURE OF BUSINESS

           Knology Broadband, Inc. (the "Company"), formerly KNOLOGY Holdings,
       Inc., is a wholly owned subsidiary of Knology, Inc. The Company offers
       residential and business customers broadband communications services,
       including analog and digital cable television, local and long distance
       telephone, high-speed Internet access service, and other services
       including broadband carrier services, using high capacity hybrid
       fiber-coaxial networks that are two-way interactive. The Company operates
       interactive broadband networks in six metropolitan areas (collectively
       the "Systems"): Huntsville and Montgomery, Alabama; Columbus and Augusta,
       Georgia; Panama City, Florida; and Charleston, South Carolina.

           The Company has experienced operating losses as a result of the
       expansion of the advanced broadband communications networks and services
       into new and existing markets. Management expects to continue the focus
       on increasing the customer base and expanding the broadband operations.
       Accordingly, operating expenses and capital expenditures will continue to
       increase with the extension of the broadband communications networks in
       existing markets in accordance with the business plan. While management
       expects its plans to result in profitability, there can be no assurance
       that growth in the Company's revenue or customer base will continue or
       that the Company will be able to achieve or sustain profitability and/or
       positive cash flow.

2.   BASIS OF PRESENTATION

           The accompanying unaudited condensed consolidated financial
       statements of the Company have been prepared in accordance with generally
       accepted accounting principles for interim financial information and with
       the instructions to Form 10-Q and Article 10 of Regulation S-X.
       Accordingly, they do not include all of the information and footnotes
       required by generally accepted accounting principles for complete
       financial statements. In the opinion of management, all adjustments
       considered necessary for the fair presentation of the financial
       statements have been included, and the financial statements present
       fairly the financial position and results of operations for the interim
       periods presented. Operating results for the three and nine months ended
       September 30, 2000 are not necessarily indicative of the results that may
       be expected for the year ended December 31, 2000. These financial
       statements should be read in conjunction with the consolidated financial
       statements and notes thereto, together with management's discussion and
       analysis of financial condition and results of operations contained in
       the Company's 1999 Annual Report on Form 10-K for the year ended December
       31, 1999.

           Certain amounts included in the 1999 financial statements have been
       reclassified to conform to the 2000 financial statements.

3.   SEGMENT INFORMATION

           Effective January 1998, the Company adopted SFAS 131, "Disclosures
       about Segments of an Enterprise and Related Information," which
       established revised standards for the reporting of financial and
       descriptive information about operating segments in financial statements.

           The Company owns and operates advanced hybrid fiber-coaxial networks
       and provides residential and business customers broadband communications
       services, including analog and digital cable television, local and long
       distance telephone, and high-speed Internet access, which the Company
       refers to as video, voice and data services. The Company also provides
       broadband carrier services which includes local transport services such
       as local Internet transport, special access, local private line, and
       local loop services.

           While management of the Company monitors the revenue generated from
       each of the various broadband services,

                                      5
<PAGE>   7

       operations are managed and financial performance is evaluated based upon
       the delivery of multiple services to customers over a single network. As
       a result of multiple services being provided over a single network, many
       expenses and assets are shared related to providing the various broadband
       services to customers. Management believes that any allocation of the
       shared expenses or assets to the broadband services would be subjective
       and impractical.

           Revenues by broadband communications service are as follows:

ITEM 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

    THE MANAGEMENT'S DISCUSSION AND ANALYSIS AND OTHER PORTIONS OF THIS REPORT
INCLUDE "FORWARD-LOOKING" STATEMENTS WITHIN THE MEANING OF THE FEDERAL
SECURITIES LAWS, INCLUDING THE PRIVATE SECURITIES LITIGATION REFORM ACT, THAT
ARE SUBJECT TO FUTURE EVENTS, RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL
RESULTS TO DIFFER MATERIALLY FROM THOSE EXPRESSED OR IMPLIED. IMPORTANT FACTORS
THAT EITHER INDIVIDUALLY OR IN THE AGGREGATE COULD CAUSE ACTUAL RESULTS TO
DIFFER MATERIALLY FROM THOSE EXPRESSED INCLUDE, WITHOUT LIMITATION, (1) THAT WE
WILL NOT RETAIN OR GROW OUR CUSTOMER BASE, (2) THAT WE WILL FAIL TO BE
COMPETITIVE WITH EXISTING AND NEW COMPETITORS, (3) THAT WE WILL NOT ADEQUATELY
RESPOND TO TECHNOLOGICAL DEVELOPMENTS IMPACTING OUR INDUSTRY AND MARKETS, (4)
THAT NEEDED FINANCING WILL NOT BE AVAILABLE IF AND AS NEEDED, (5) THAT A
SIGNIFICANT CHANGE IN THE GROWTH RATE OF THE OVERALL U.S. ECONOMY WILL OCCUR
SUCH THAT CONSUMER AND CORPORATE SPENDING ARE MATERIALLY IMPACTED, AND (6) THAT
SOME OTHER UNFORESEEN DIFFICULTIES OCCUR. THIS LIST IS INTENDED TO IDENTIFY ONLY
CERTAIN OF THE PRINCIPAL FACTORS THAT COULD CAUSE ACTUAL RESULTS TO DIFFER
MATERIALLY FROM THOSE DESCRIBED IN THE FORWARD-LOOKING STATEMENTS INCLUDED
HEREIN.

    The following is a discussion of our consolidated financial condition and
results of operations for the three and nine months ended September 30, 2000 and
certain factors that are expected to affect our prospective financial condition.
The following discussion and analysis should be read in conjunction with the
financial statements and notes thereto and other financial data included
elsewhere in this Form 10-Q.


GENERAL

    We offer residential and business customers broadband services, including
analog and digital cable television, local and long distance telephone,
high-speed Internet access service, and broadband carrier services. We provide
these broadband services using high capacity hybrid fiber-coaxial networks that
are two-way interactive. We own, operate and manage interactive broadband
networks in six metropolitan areas: Huntsville and Montgomery, Alabama; Columbus
and Augusta, Georgia; Panama City, Florida and Charleston, South Carolina.

    We have been expanding our networks and adding corporate staffing necessary
to grow the business. Accordingly, our operating expenses and capital
expenditures have increased significantly and are expected to continue to
increase with the continued expansion of the existing systems.

    We have incurred net losses in each quarter since our inception, and as of
September 30, 2000, the accumulated deficit had reached approximately $185.9
million. We anticipate incurring net losses during the next several years while
continuing to expand operations, and as a result of substantially increased
depreciation and amortization from the construction of our interactive broadband
networks and operating expenses incurred in building the customer base. There
can be no assurance that growth in revenue or the subscriber base will continue
or that we will be able to achieve or sustain profitability or positive cash
flow.

REVENUES AND EXPENSES

We can group our revenues into four categories: video revenues, voice revenues,
data revenues and other revenues.

-      Video revenues. Our video revenues consist of fixed monthly fees for
       basic, premium and digital cable television services, as well as fees
       from pay-per-view movies and events such as boxing matches and concerts,
       that involve a charge for each viewing. Video revenues accounted for
       approximately 67% and 69% of our consolidated revenues for the three and
       nine months ended September 30, 2000 compared to 73% and 78% for the
       three and nine months ended September 30, 1999.

-      Voice revenues. Our voice revenues consist primarily of fixed monthly
       fees for local service, enhanced services such as call waiting and voice
       mail, and usage fees for long distance service. Voice revenues accounted
       for approximately 23% and 21% of our consolidated revenues for the three
       and nine months ended September 30, 2000 compared to 21% and 18% for the
       three and nine months ended September 30, 1999.

-      Data revenues and other revenues. Our data revenues consist primarily of
       fixed monthly fees for Internet access service and rental of cable
       modems. Other revenues resulted principally from broadband carrier
       services and video production services. These combined revenues accounted
       for approximately 10% and 10% of our consolidated revenues for the three
       and nine months ended September 30, 2000 compared to 6% and 4% for the
       three and nine months ended September 30, 1999.

Our operating expenses include cost of services expenses, selling, operations
and administrative expenses and depreciation and amortization expenses.

Cost of services expenses include:

-     Video cost of services. Video cost of services consist primarily of
      monthly fees to the National Cable Television Cooperative and other
      programming providers, and are generally based on the average number of
      subscribers to each program. Programming costs as a percentage of video
      revenue were approximately 45% and 44% for the three and nine months ended
      September 30, 2000 compared to 42% and 42% for the three and nine months
      ended September 30, 1999. Programming costs is our largest single cost and
      we expect this to continue. Since this cost is based on numbers of
      subscribers, it will increase as we add more subscribers.

-     Voice and data services. Cost of services related to our voice and data
      services include costs of Internet transport and telephone switching, and
      interconnection and transport charges payable to local and long distance
      carriers.

Selling, operations and administrative expenses include:

-     Sales and marketing costs. Sales and marketing costs include the cost of
      sales and marketing personnel, and advertising and promotional expenses.

-     Network operations and maintenance expenses. Network operations and
      maintenance expenses include payroll and departmental costs incurred for
      network design and maintenance activity.

-     Customer service expenses. Customer service expenses include payroll and
      departmental costs incurred for customer service representatives and
      management.

-     General and administrative expenses. General and administrative expenses
      consist of corporate and subsidiary general management and administrative
      costs.

      Depreciation and amortization expenses include depreciation of our
interactive broadband networks and equipment, and amortization of cost in excess
of net assets and other intangible assets related to acquisitions.

1999 to $1.5 million for the same period in 2000, $1.3 million of which were
revenues from data services. The increased revenues for video, voice and data
and other services are primarily due to increases in the number of connections
from September 30, 1999 to September 30, 2000 of 11,644 or 13.7% for video,
17,234 or 105% for voice and 8,439 or 247% for data. The additional connections
resulted primarily from the extension and/or upgrade of our broadband networks,
and marketing and sales efforts.

    Expenses. Our operating expenses, excluding depreciation and amortization,
increased 34.8%, from $14.7 million for the three months ended September 30,
1999, to $19.9 million for the three months ended September 30, 2000. The cost
of services component of operating expenses increased 20.5%, from $5.6 million
for the three months ended September 30, 1999 to $6.7 for the three months ended
September 30, 2000. The increase in our cost of services is consistent with the
growth in connections and revenues. The increase in operating expenses is a
result of the expansion of the operations and the increase in the number of
employees associated with such expansion.

    Our depreciation and amortization expenses increased 46.6% from $9.2 million
for the three months ended September 30, 1999, to $13.6 million for the three
months ended September 30, 2000. The increase in depreciation is primarily due
to the expansion of our networks.

    Other Income and Expenses. Our interest income was approximately $143,000
for the three months ended September 30, 1999, compared to $28,000 for the three
months ended September 30, 2000. The interest income reflects the interest
earned from the investment of certain proceeds received from the issuance of the
senior discount notes in October 1997. The decrease in interest income is due to
the draw down of marketable securities to fund planned expansion.

    Our interest expense increased from $8.0 million for the three months ended
September 30, 1999 to $9.8 million for the three months ended September 30,
2000. The increase in interest expense reflects the accrual of the interest
attributable to the senior discount notes issued in October 1997.

    Income Tax Benefit. We recorded an income tax benefit of $4.7 million for
the three months ended September 30, 1999 compared to no income tax benefit for
the three months ended September 30, 2000. The income tax benefit in 1999
resulted from our utilizing net tax losses under a tax sharing agreement with
ITC Holding Company, Inc.

    Net Loss. We incurred a net loss of $15.1 million for the three months ended
September 30, 1999 compared to a net loss of $28.1 million for the three months
ended September 30, 2000. The increase in net loss is a result of the expansion
of our operations and the increase in the number of employees associated with
such expansion.

1999, to $54.7 million for the nine months ended September 30, 2000. The cost of
