  You should carefully review the information contained in this Quarterly Report
and in other reports or documents that we file from time to time with the
Securities and Exchange Commission (the "SEC").  In this Quarterly Report, we
state our beliefs of future events and of our future financial performance.  In
some cases, you can identify those so-called "forward-looking statements" by
words such as "may," "will," "should," "expects," "plans," "anticipates,"
"believes," "estimates," "predicts," "potential," or "continue" or the negative
of those words and other comparable words.  You should be aware that those
statements are only our predictions.  Actual events or results may differ
materially.  In evaluating those statements, you should specifically consider
various factors, including the risks discussed in our Annual Report on Form 10-K
for the year-ended December 31, 2000 and other reports that we file from time to
time with the SEC.  Those factors may cause our actual results to differ
materially from any of our forward-looking statements.  All forward-looking
statements attributable to us or a person acting on our behalf are expressly
qualified in their entirety by this cautionary statement.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)


(1)  Organization

  Mediacom Communications Corporation ("MCC," and collectively with its direct
and indirect subsidiaries, the "Company") is involved in the acquisition and
development of cable television systems serving principally non-metropolitan
markets in the United States. Through these cable systems, the Company provides
entertainment, information and telecommunications services to its subscribers.
As of June 30, 2001, the Company had acquired and was operating cable systems in
22 states, principally Alabama, California, Florida, Illinois, Indiana, Iowa,
Kentucky, Minnesota, Missouri and North Carolina.

  MCC, a Delaware corporation organized in November 1999, completed an initial
public offering on February 9, 2000. Prior to the initial public offering, MCC
had no assets, liabilities, contingent liabilities or operations.  Immediately
prior to the completion of its initial public offering, MCC issued shares of its
Class A and Class B common stock in exchange for all of the outstanding
membership interests in Mediacom LLC, a New York limited liability company
organized in July 1995.  As a result of this exchange, Mediacom LLC became a
wholly-owned subsidiary of MCC.

  On February 26, 2001, the Company entered into four separate definitive asset
purchase agreements with AT&T Broadband, LLC under which various affiliates of
AT&T Broadband agreed to sell to the Company certain cable television systems in
the states of Georgia, Illinois, Iowa and Missouri (the "AT&T systems"), subject
to several closing conditions.  See Notes 3 and 8.

  Mediacom Broadband LLC ("Mediacom Broadband"), a wholly-owned subsidiary of
MCC, was organized as a Delaware limited liability company in April 2001 for the
purpose of acquiring the AT&T systems.  Mediacom Broadband Corporation, a
Delaware corporation wholly-owned by Mediacom Broadband, was organized in May
2001 for the sole purpose of acting as co-issuer with Mediacom Broadband of
$400.0 million aggregate principal amount of the 11% senior notes due July 15,
2013. Mediacom Broadband Corporation does not conduct operations of its own.

presentation and amounts to conform to the current year's presentation and
amounts.

  The consolidated financial statements as of June 30, 2001 and 2000 are
unaudited.  However, in the opinion of management, such statements include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the results for the periods presented.  The accounting
policies followed during such interim periods reported are in conformity with
generally accepted accounting principles and are consistent with those applied
during annual periods.  For additional disclosures, including a summary of the
Company's accounting policies, the interim financial statements should be read
in conjunction with the Company's Annual Report on Form 10-K for the year ended
December 31, 2000 (File No. 0-29227).  The results of operations for the interim
periods are not necessarily indicative of the results that might be expected for
future interim periods or for the full year ending December 31, 2001.

 Recent Accounting Pronouncements

  In June 1998, Statement of Financial Accounting Standards No. 133 ("SFAS
133"), "Accounting for Derivative Instruments and Hedging Activities," was
issued effective January 1, 2001.  This statement establishes the accounting and
reporting standards for derivatives and hedging activity.  Upon adoption of SFAS
133, all derivatives are required to be recognized in the statement of financial
position as either assets or liabilities and measured at fair value.  The
Company recorded an after tax charge of approximately $1.6 million, as a change
in accounting principle, in the first quarter of 2001.

  In June 2001, Statement of Financial Accounting Standards No. 142 ("SFAS
142"), "Accounting for Goodwill and other Intangible Assets," was issued
effective January 1, 2002.  This statement establishes that goodwill is no
longer subject to amortization over its useful life.  The new rule also states
that an acquired intangible asset must be separately recognized if it is
obtained through contractual or other legal rights, or if the asset can be sold,
licensed, transferred, exchanged or rented, regardless of the intent to do so.
The Company has not yet determined the impact that SFAS 142 may have on its
results of operations and the consolidated financial statements.


(3)  Acquisitions

  On June 29, 2001, the Company acquired cable systems serving approximately
94,000 basic subscribers in the state of Missouri from affiliates of AT&T
Broadband, LLC, for a purchase price of approximately $308.8 million.  The
purchase price has been preliminarily allocated as follows:  approximately $84.4
million to property, plant and equipment and approximately $224.4 million to
intangible assets.  Such allocations are subject to adjustments based upon the
final appraisal information received by the Company.  This acquisition was
financed with a portion of the net proceeds from the Company's public offering
of 29.9 million shares of Class A of common stock, which was completed on June
27, 2001. See Note 1.

  During 2000, the Company completed nine acquisitions of cable systems serving
approximately 53,000 basic subscribers for an aggregate purchase price of $109.2
million, including a $2.5 million deferred conditional payment to a seller. The
cable systems serve communities in the states of Alabama, Illinois, Iowa,
Kentucky, Minnesota and South Dakota. The aggregate purchase price has been
allocated as follows: approximately $48.2 million to property, plant and
equipment, and approximately $58.5 million to intangible assets. Additionally,
approximately $2.7 million of direct acquisition costs have been allocated to
property, plant and equipment and intangible assets. These acquisitions were
financed with borrowings under the Company's subsidiary credit facilities.

  These acquisitions were accounted for using the purchase method of accounting,
and accordingly, the purchase price of each of these acquired systems have been
allocated to the assets acquired and liabilities assumed at their estimated fair
values at their respective dates of acquisition.

 Unaudited Pro Forma Information

  The Company has reported the operating results of the acquired systems from
the dates of their respective acquisition.  The unaudited pro forma operating
results presented below give pro forma effect to the acquisitions of the
acquired systems as if such transactions had been consummated on January 1,
2000.  This financial information has been prepared for comparative purposes
only and does not purport to be indicative of the operating results which
actually would have resulted had the acquisitions of the acquired systems been
consummated at the beginning of the period presented.

(4)  Loss Per Share

  The Company calculates loss per share in accordance with Statement of
Financial of Accounting Standards No. 128 ("SFAS 128"), "Earnings per Share."
SFAS 128 computes basic loss per share by dividing the net loss by the weighted
average number of shares of common stock outstanding during the period.  Diluted
loss per share is computed by dividing the net loss by the weighted average
number of shares of common stock outstanding during the period plus the effects
of any potentially dilutive securities.  Since the Company has reported a net
loss for the periods, the effects of the inclusion of stock options and
convertible debt would be anti-dilutive and therefore, in accordance with SFAS
128, are not included in the computation of diluted loss per share.

  The following table summarizes the Company's calculation of basic and diluted
loss per share for the three and six months ended June 30, 2001 and 2000:

Debt Issued in 2001

(a)  On January 24, 2001, Mediacom LLC and its wholly-owned subsidiary, Mediacom
     Capital Corporation jointly issued $500.0 million aggregate principal
     amount of 9 1/2% senior notes due January 2013 (the "9 1/2% Senior Notes").
     The 9 1/2% Senior Notes are unsecured obligations of Mediacom LLC, and the
     indenture for the 9 1/2% Senior Notes stipulates, among other things,
     restrictions on incurrence of indebtedness, distributions, mergers and
     asset sales and has cross-default provisions related to other debt of
     Mediacom LLC. Mediacom LLC was in compliance with the indenture governing
     the 9 1/2% Senior Notes as of June 30, 2001.

(b)  On June 29, 2001, Mediacom Broadband and Mediacom Broadband Corporation
     jointly issued $400.0 million aggregate principal amount of 11% senior
     notes due July 2013 (the "11% Senior Notes"). The 11% Senior Notes are
     unsecured obligations of Mediacom Broadband, and the indenture for the 11%
     Senior Notes stipulates, among other things, restrictions on incurrence of
     indebtedness, distributions, mergers and asset sales and has cross-default
     provisions related to other debt of Mediacom Broadband. The 11% Senior
     Notes were also subject to a special mandatory redemption if all of the
     acquisitions of the AT&T systems had not been consummated on or prior to
     specified date, at a price equal to 101% of the principal amount thereof,
     together with accrued and unpaid interest to the date of redemption.

     Mediacom Broadband placed the net proceeds of the offering of the 11%
     Senior Notes, along with the additional amount of cash necessary to fund
     the special mandatory redemption, including the accrued interest, in an
     escrow account, pending application of the escrow funds by Mediacom
     Broadband for the payment of (i) a portion of the purchase price for the
     acquisitions of the AT&T systems and related fees and expenses or (ii) in
     the event of a special mandatory redemption of the 11% Senior Notes, the
     redemption price in connection therewith.  The escrow funds were required
     to be invested in cash or cash equivalents and are classified as restricted
     cash on the Company's consolidated balance sheets as of June 30, 2001.
     Pursuant to the escrow agreement, the escrow funds were released to
     Mediacom Broadband on July 18, 2001 and applied towards the purchase price
     for the acquisitions of the AT&T systems and to pay related fees and
     expenses, in connection with the completion of such acquisitions on the
     same date.  See Notes 1, 3, and 8.

(c)  On June 27, 2001, the Company issued $172.5 million aggregate principal
     amount of 5 1/4% convertible senior notes ("Convertible Senior Notes") due
     July 2006. The Convertible Senior Notes are convertible at any time at the
     option of the holder into the Company's Class A common stock at an initial
     conversion rate of 53.4171 shares per $1,000 principal amount of notes,
     which is equivalent to a price of $18.72 per share. The conversion rate is
     subject to adjustment.

  The average interest rate on outstanding debt under the bank credit facilities
was 7.0% and 8.3% for the three months ended June 30, 2001 and December 31,
2000, respectively, before giving effect to the interest rate swap agreements
discussed below.

  The Company uses interest rate swap agreements in order to fix the interest
rate for the duration of the contract as a hedge against interest rate
volatility.  As of June 30, 2001, the Company had entered into interest rate
exchange agreements (the "Swaps") with various banks pursuant to which the
interest rate on $170.0 million is fixed at a weighted average swap rate of
approximately 6.7%, plus the average applicable margin over the Eurodollar Rate
option under the bank credit agreements.  Under the terms of the Swaps, which
expire from 2002 through 2004, the Company is exposed to credit loss in the
event of nonperformance by the other parties to the Swaps.  However, the Company
does not anticipate nonperformance by the counterparties.

  The stated maturities of all debt outstanding as of June 30, 2001 are as
  follows (dollars in thousands):

(6)  SoftNet

  As of December 31, 2000, deferred revenue resulting from the Company's receipt
of shares of SoftNet Systems, Inc. common stock amounted to approximately $30.2
million, net of amortization taken.  As of January 31, 2001, the Company
formally terminated its relationship with SoftNet in all material respects.  The
Company recognized revenue of approximately $0.3 million and $0.9 million for
the six months ended June 30, 2001 and 2000, respectively.  As a result of the
termination of the SoftNet relationship in the first quarter of 2001, the
Company recognized the remaining deferred revenue of approximately $30.0 million
as other income in the consolidated statements of operations.


(7)  Stockholders' Equity

  On June 27, 2001, the Company completed a public offering of 29.9 million
shares of its Class A Common Stock at $15.22 per share. The net proceeds, after
underwriting discounts and other expenses of approximately $22.1 million, were
$433.0 million. Net proceeds from this offering were used to fund a portion of
the purchase price for the acquisitions of the AT&T systems. See Notes 3 and
8.



(8)  Subsequent Events

  On July 18, 2001, Mediacom Broadband acquired cable systems serving
approximately 706,000 basic subscribers in the states of Georgia, Illinois and
Iowa from affiliates of AT&T Broadband, LLC, for an aggregate price of
approximately $1.79 billion. See Notes 1 and 3.

Notes, the escrow funds comprising the net proceeds of the offering of such
notes, along with the additional amounts representing the special mandatory
redemption, were released to the Company.  Such escrow funds were applied toward
the purchase price for the acquisitions of the AT&T systems. See Note 5.

  On July 18, 2001, the Company completed a $1.4 billion senior secured credit
facility for the operating subsidiaries of Mediacom Broadband.  Borrowings under
this facility, in the amount of $855.0 million, were used to fund a portion of
the purchase price for the acquisitions of the AT&T systems. See Notes 1 and 3.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS


Introduction

  The Company does not believe the discussion and analysis of its historical
financial condition and results of operations set forth below are indicative,
nor should they be relied upon as an indicator, of its future performance
because of certain significant past events.  Those events include numerous
acquisitions and several financing transactions.

Organization

  Mediacom Communications Corporation ("MCC") was organized as a Delaware
corporation in November 1999 and completed an initial public offering in
February 2000.  Immediately prior to the completion of its initial public
offering, MCC issued shares of common stock in exchange for all of the
outstanding membership interests in Mediacom LLC, a New York limited liability
company.  Mediacom LLC commenced operations in March 1996.

  Until MCC's initial public offering in February 2000, Mediacom Management
Corporation, a Delaware corporation, provided management services to the
operating subsidiaries of Mediacom LLC and received annual management fees.
Mediacom Management utilized these fees to compensate its employees as well as
to fund its corporate overhead.  Such management fees were 2% of the Company's
annual gross revenues.  The management agreements were terminated upon the date
of MCC's initial public offering.  At that time, Mediacom Management's employees
became the Company's employees and its corporate overhead became the Company's
corporate overhead.  These expenses are reflected as corporate expenses in the
consolidated statements of operations.

Acquisitions

  The Company has significantly expanded its business through acquisitions.  All
acquisitions have been accounted for under the purchase method of accounting
and, therefore, the Company's historical results of operations include the
results of operations for each acquired system subsequent to its respective
acquisition date.

  AT&T Acquisitions

  On February 26, 2001, the Company entered into four separate definitive asset
purchase agreements with AT&T Broadband, LLC under which various affiliates of
AT&T Broadband agreed to sell to the Company certain cable television systems in
the states of Georgia, Illinois, Iowa and Missouri (the "AT&T systems"), subject
to several closing conditions.

  On June 29, 2001, the Company completed the acquisition of AT&T cable systems
serving approximately 94,000 basic subscribers in the state of Missouri (the
"Missouri systems"). The purchase price for the Missouri systems was
approximately $309 million, after preliminary closing adjustments. This
transaction comprises cable systems serving Columbia, Jefferson City and
Springfield, Missouri.

  On July 18, 2001, the Company completed the acquisitions of AT&T cable systems
serving approximately 706,000 basic subscribers in the states of Georgia,
Illinois and Iowa. The aggregate purchase price for these cable systems was
approximately $1.79 billion, after preliminary closing adjustments. These
transactions include cable systems serving the cities and surrounding
communities of Albany, Columbus, Tifton and Valdosta, Georgia; Charleston,
Carbondale, Effingham, Marion, Moline and Rock Island, Illinois; and Ames, Cedar
Rapids, Clinton, Davenport, Des Moines, Dubuque, Fort Dodge, Iowa City, Mason
City and Waterloo, Iowa.

 2000 Acquisitions

  In 2000, the Company completed nine acquisitions of cable systems serving a
total of approximately 53,000 basic subscribers (the "2000 Acquisitions").  The

General

  EBITDA represents operating loss before depreciation and amortization and non-
cash stock charges relating to corporate expenses. EBITDA:

  . is not intended to be a performance measure that should be regarded as an
    alternative either to operating income or net income as an indicator of
    operating performance, or to the statement of cash flows as a measure of
    liquidity;

  . is not intended to represent funds available for debt service, dividends,
    reinvestment or other discretionary uses; and

  . should not be considered in isolation or as a substitute for measures of
    performance prepared in accordance with generally accepted accounting
    principles.

  EBITDA is included herein because the Company's management believes that
EBITDA is a meaningful measure of performance as it is commonly used by the
cable television industry and by the investment community to analyze and compare
cable television companies.  The Company's definition of EBITDA may not be
identical to similarly titled measures reported by other companies.


Actual Results of Operations

  The following historical information includes the results of operations of the
2000 Acquisitions and the Missouri systems (together, the "Acquired Systems"),
only for that portion of the respective period that such cable television
systems were owned by the Company.

 Three Months Ended June 30, 2001 Compared to Three Months Ended June 30, 2000

  Revenues.  Revenues increased 12.7% to $93.1 million for the three months
ended June 30, 2001 as compared to $82.6 million for the three months ended June
30, 2000.  Of the revenue increase of $10.5 million, approximately $5.1 million
was attributable to the Acquired Systems.  Excluding the Acquired Systems,
revenues increased primarily due to basic rate increases associated with new
programming introductions in the Company's core television services and to
customer growth in the Company's recently launched digital cable and high-speed
Internet access services.

                                       10
<PAGE>

  Service costs.  Service costs increased 15.4% to $32.6 million for the three
months ended June 30, 2001 as compared to $28.2 million for the three months
ended June 30, 2000.  Of the service cost increase of $4.4 million,
approximately $2.0 million was attributable to the Acquired Systems.  Excluding
the Acquired Systems, these costs increased primarily as a result of higher
programming expenses, including rate increases by programmers and the costs of
channel additions.  As a percentage of revenues, service costs were 35.0% for
the three months ended June 30, 2001, as compared with 34.2% for the three
months ended June 30, 2000.

  Selling, general and administrative expenses.  Selling, general and
administrative expenses increased 6.8% to $14.8 million for the three months
ended June 30, 2001 as compared to $13.9 million for the three months ended June
30, 2000.  Of the selling, general and administrative expense increase of $0.9
million, approximately $0.7 million was attributable to the Acquired Systems.
Excluding the Acquired Systems, these costs increased primarily as a result of
higher customer service employee expense.  As a percentage of revenues, selling,
general and administrative expenses were 15.9% for the three months ended June
30, 2001 as compared with 16.8% for the three months ended June 30, 2000.

  Corporate expenses.  Corporate expenses increased 29.1% to $2.0 million for
the three months ended June 30, 2001 as compared to $1.5 million for the three
months ended June 30, 2000.  As a percentage of revenues, corporate expenses
were 2.1% for the three months ended June 30, 2001 as compared with 1.8% for the
three months ended June 30, 2000.  The increase is primarily due to additional
employee costs as a result of the anticipated AT&T acquisitions.

  Depreciation and amortization. Depreciation and amortization increased 22.2%
to $53.1 million for the three months ended June 30, 2001 as compared to $43.5
million for the three months ended June 30, 2000.  This increase was due to the
Company's purchase of the Acquired Systems and capital expenditures associated
with the upgrade of the Company's cable systems.

  Non-cash stock charges relating to corporate expenses.  Non-cash stock charges
relating to corporate expenses decreased 24.7% to $0.7 million for the three
months ended June 30, 2001 as compared to $0.9 million for the three months
ended June 30, 2000.  This decrease is due to reduced vesting in equity
interests granted to certain members of MCC's management team.

  Interest expense, net.  Interest expense, net, increased 38.8% to $22.4
million for the three months ended June 30, 2001 as compared to $16.2 million
for the three months ended June 30, 2000.  This increase was primarily due to a
higher interest rate associated with the Company's 9 1/2% senior notes, which
were issued in January 2001.

  Other (income) expenses.  Other expense was $0.1 million for the three months
ended June 30, 2001 as compared to $0.4 million of other expense for the three
months ended June 30, 2000.  This change was principally due to the recording of
the fair value of the Company's interest rate derivatives as a result of the
adoption of SFAS 133.

  Provision (benefit) for income taxes.  Provision for income taxes was $0.1
million for the three months ended June 30, 2001 as compared to a $3.3 million
benefit for the three months ended June 30, 2000.  This provision reflects the
net tax effect of temporary differences between the carrying amounts of assets
and liabilities for financial reporting purposes and the amounts used for income
tax purposes.

  Net loss.  Due to the factors described above, the Company generated a net
loss of $32.7 million for the three months ended June 30, 2001 as compared to a
net loss of $18.7 million for the three months ended June 30, 2000.

  EBITDA. EBITDA increased 12.2% to $43.7 million for the three months ended
June 30, 2001 as compared to $39.0 million for the three months ended June 30,
2000.  Of the EBITDA increase of $4.7 million, approximately $2.3 million was
attributable to the Acquired Systems.  Excluding the Acquired Systems, EBITDA
increased primarily due to the increase in revenues described above, offset
primarily by the increases in programming expenses and customer service employee
expense described above. As a percentage of revenues, EBITDA was 47.0% for the
three months ended June 30, 2001 as compared with 47.2% for the three months
ended June 30, 2000.

 Six Months Ended June 30, 2001 Compared to Six Months Ended June 30, 2000

  Revenues.  Revenues increased 14.6% to $183.4 million for the six months ended
June 30, 2001 as compared to $160.0 million for the six months ended June 30,
2000.  Of the revenue increase of $23.4 million, approximately $11.2 million was
attributable to the Acquired Systems.  Excluding the Acquired Systems, revenues
increased primarily due to basic rate increases associated with new programming
introductions in the Company's core television services and to customer growth
in the Company's recently launched digital cable and high-speed Internet access
services.

  Service costs.  Service costs increased 16.7% to $64.1 million for the six
months ended June 30, 2001 as compared to $54.9 million for the six months ended
June 30, 2000.  Of the service cost increase of $9.2 million, approximately $4.5
million was attributable to the Acquired Systems.  Excluding the Acquired
Systems, these costs increased primarily as a result of higher programming
expenses, including rate increases by programmers and the costs of channel
additions.  As a percentage of revenues, service costs were 34.9% for the six
months ended June 30, 2001, as compared with 34.3% for the six months ended June
30, 2000.

  Selling, general and administrative expenses.  Selling, general and
administrative expenses increased 10.0% to $30.0 million for the six months
ended June 30, 2001 as compared to $27.3 million for the six months ended June
30, 2000.  Of the selling, general and administrative expense increase of $2.7
million, approximately $1.8 million was attributable to the Acquired Systems.
Excluding the Acquired Systems, these costs increased primarily as a result of
higher customer service employee expense and marketing costs associated with the
promotion of the Company's new product offerings.  As a percentage of revenues,
selling, general and administrative expenses were 16.4% for the six months ended
June 30, 2001 as compared with 17.0% for the six months ended June 30, 2000.

  Corporate expenses.  Corporate expenses increased 18.3% to $3.5 million for
the six months ended June 30, 2001 as compared to $2.9 million for the six
months ended June 30, 2000.  As a percentage of revenues, corporate expenses
were 1.9% for the six months ended June 30, 2001 as compared with 1.8% for the
six months ended June 30, 2000.  The increase is primarily due to additional
employee costs as a result of the anticipated AT&T acquisitions.

  Depreciation and amortization. Depreciation and amortization increased 23.7%
to $104.1 million for the six months ended June 30, 2001 as compared to $84.2
million for the six months ended June 30, 2000.  This increase was due to the
Company's purchase of the Acquired Systems and capital expenditures associated
with the upgrade of the Company's cable systems.

  Non-cash stock charges relating to corporate expenses.  Non-cash stock charges
relating to corporate expenses decreased 93.0% to $1.9 million for the six
months ended June 30, 2001 as compared to $27.0 million for the six months ended
June 30, 2000.  This decrease is due to a one-time $24.5 million charge which
occurred in February 2000, resulting from the termination of the management
agreements with Mediacom Management on the date of MCC's initial public
offering.

  Interest expense, net.  Interest expense, net, increased 24.8% to $43.2
million for the six months ended June 30, 2001 as compared to $34.6 million for
the six months ended June 30, 2000.  This increase was primarily due to a higher
interest rate associated with the Company's 9 1/2% senior notes, which were
issued in January 2001.

  Other (income) expenses.  Other income was $27.7 million for the six months
ended June 30, 2001 as compared to $0.9 million of other expenses for the six
months ended June 30, 2000.  This change was principally due to the elimination
of the remainder of the deferred SoftNet revenue resulting from the termination
of the contract with SoftNet Systems, Inc.  (See Note 6).

  Provision (benefit) for income taxes.  Provision for income taxes decreased to
$0.1 million for the six months ended June 30, 2001 as compared to $1.3 million
provision for the six months ended June 30, 2000.  This provision reflects the
net tax effect of temporary differences between the carrying amounts of assets
and liabilities for financial reporting purposes and the amounts used for income
tax purposes.

  Net loss.  Due to the factors described above and a one-time charge of $1.6
million resulting from the cumulative effect of change in accounting principle,
the Company generated a net loss of $37.3 million for the six months ended June
30, 2001 as compared to a net loss of $72.9 million for the six months ended
June 30, 2000.

  EBITDA. EBITDA increased 14.6% to $85.9 million for the six months ended June
30, 2001 as compared to $75.0 million for the three months ended June 30, 2000.
Of the EBITDA increase of $10.9 million, approximately $4.6 million was
attributable to the Acquired Systems. Excluding the Acquired Systems, EBITDA
increased primarily due to the increase in revenues described above, offset
primarily by the increases in programming expenses and customer service employee
expense described above.  As a percentage of revenues, EBITDA was 46.8% for the
six months ended June 30, 2001 and 2000.

  Selected Pro Forma Results for Six Months Ended June 30, 2001 Compared to
Selected Pro Forma Results for Six Months Ended June 30, 2000

  Revenues increased 8.7% to $212.1 million for the six months ended June 30,
2001, as compared to $195.1 million for the six months ended June 30, 2000.
This increase was attributable principally to basic rate increases associated
with new programming introductions in the Company's core television services,
internal subscriber growth of 0.4% and to customer growth in the Company's
recently launched digital cable and high-speed Internet access services.

  Service costs and selling, general and administrative expenses in the
aggregate increased 7.8% to $111.0 million for the six months ended June 30,
2001 from $103.0 million for the six months ended June 30, 2000, principally due
to higher programming expenses and customer service employee expense.

  Corporate expenses increased 37.7% to $5.2 million for the six months ended
June 30, 2001 from $3.8 million for the six months ended June 30, 2000.  As a
percentage of revenues, corporate expenses were 2.5% for the six months ended
June 30, 2001 as compared with 1.9% for the six months ended June 30, 2000.

  Depreciation and amortization increased 14.4% to $117.4 million for the six
months ended June 30, 2001 from $102.7 million for the six months ended June 30,
2000.  This increase was principally due to capital expenditures associated with
the upgrade of the Company's cable systems.  Non-cash stock charges relating to
corporate expenses were as reported above.

  As a result of the above factors, the Company generated an operating loss of
$23.4 million for the six months ended June 30, 2001, compared to $41.3 million
for the six months ended June 30, 2000.

  EBITDA increased by 8.5% to $95.9 million for the six months ended June 30,
2001 from $88.4 million for the six months ended June 30, 2000.  The EBITDA
margin was 45.2% for the six months ended June 30, 2001 as compared with 45.3%
for the six months ended June 30, 2000.


Liquidity and Capital Resources

  The Company's business requires substantial capital for the upgrade, expansion
and maintenance of its cable network.  In addition, the Company has pursued, and
will continue to pursue, a business strategy that includes selective
acquisitions. The Company has funded and will continue to fund its working
capital requirements, capital expenditures and acquisitions through a
combination of internally generated funds, long-term borrowings and equity
financings.

 Investing Activities

  On February 26, 2001, the Company entered into four separate definitive asset
purchase agreements with AT&T Broadband, LLC under which various affiliates of
AT&T Broadband agreed to sell to the Company certain cable television systems in
Georgia, Illinois, Iowa and Missouri, subject to several closing conditions.

  On June 29, 2001, the Company completed the acquisition of AT&T cable systems
serving approximately 94,000 basic subscribers in Missouri. The purchase price
for the Missouri systems was approximately $309 million, after preliminary
closing adjustments. This transaction comprises cable systems serving Columbia,
Jefferson City and Springfield, Missouri.

  On July 18, 2001, the Company completed the acquisitions of AT&T cable systems
serving approximately 706,000 basic subscribers in Georgia, Illinois and Iowa.
The aggregate purchase price for these cable systems was approximately $1.79
billion, after preliminary closing adjustments. These transactions include cable
systems serving the cities and surrounding communities of Albany, Columbus,
Tifton and Valdosta, Georgia; Charleston, Carbondale, Effingham, Marion, Moline
and Rock Island, Illinois; and Ames, Cedar Rapids, Clinton, Davenport, Des
Moines, Dubuque, Fort Dodge, Iowa City, Mason City and Waterloo, Iowa.

  In 2000, the Company completed nine acquisitions of cable systems that served
approximately 53,000 basic subscribers for an aggregate purchase price of $109.2
million.

  As a result of the Company's recent acquisitions of the AT&T systems, the
Company has revised its capital investment program and now expects to spend
approximately $310 million on capital expenditures in 2001.  This revision also
reflects an acceleration of the Company's previously announced network upgrade
plan.  The Company plans to fund these expenditures through net cash flows from
operations and additional borrowings under its subsidiary bank credit
facilities.  By December 2001, including the AT&T systems, the Company expects
that 77% of its cable network will be upgraded with 550MHz to 870MHz bandwidth
capacity and 68% of its homes passed will have two-way communications.  For the
six months ended June 30, 2001, the Company's capital expenditures were $108.5
million.

 Financing Activities

  The AT&T systems were acquired by operating subsidiaries of Mediacom Broadband
LLC, a newly-formed, wholly-owned subsidiary of the Company. The aggregate
purchase price of $2.1 billion for the AT&T systems, together with related fees
and expenses and working capital, was financed through a combination of:

  . Borrowings under the $1.4 billion credit facility of the operating
    subsidiaries of Mediacom Broadband in the amount of $855.0 million;

  . Borrowings under the aggregate $1.1 billion credit facilities of the
    operating subsidiaries of Mediacom LLC, a wholly-owned subsidiary of the
    Company, in the amount of $275.0 million;

  . Gross proceeds from the Company's sale of its Class A common stock in the
    amount of $455.1 million;

  . Gross proceeds from the Company's sale of its 5 1/4% convertible senior
    notes in the aggregate principal amount of $172.5 million; and

  . Gross proceeds from Mediacom Broadband's sale of its 11% senior notes in the
    aggregate principal amount of $400.0 million.

  The credit facility of Mediacom Broadband's operating subsidiaries, the sale
of the Company's Class A common stock, the sale of the Company's 5 1/4%
convertible senior notes and the sale of Mediacom Broadband's 11% senior notes
are discussed below.

  On January 24, 2001, Mediacom LLC and, its wholly-owned subsidiary, Mediacom
Capital Corporation, completed an offering of $500.0 million of 9 1/2% senior
notes due January 2013.  Interest on the 9 1/2% senior notes is payable semi-
annually on January 15 and July 15 of each year, which commenced on July 15,
2001.  Approximately $467.5 million of the net proceeds were used to repay a
substantial portion of the indebtedness outstanding under the Company's
subsidiary credit facilities and related accrued interest.  The balance of the
net proceeds was used for general corporate purposes.

  On June 27, 2001, the Company completed a public offering of 29.9 million
shares of its Class A common stock at $15.22 per share.  The transaction
included 3.9 million shares of Class A common stock issued pursuant to the
exercise of an over-allotment option by the underwriters of the offering.  The
net proceeds from this offering were used to pay a portion of the purchase price
of the acquisitions of AT&T systems.

  On June 27, 2001, the Company completed a public offering of $172.5 million of
5 1/4% convertible senior notes due July 2006.  The transaction included $22.5
million of convertible senior notes issued pursuant to the exercise of an over-
allotment option  by the underwriters of the offering.  Interest on the 5 1/4%
convertible senior notes is payable semi-annually on January 1 and July 1 of
each year, commencing January 1, 2002.  The convertible senior notes are
convertible at any time into the Company's Class A common stock at an initial
conversion rate of 53.4171 shares per $1,000 principal amount of notes, which is
equivalent to a price of $18.72 per share.  The conversion rate is subject to
adjustment.  The net proceeds from this offering were used to pay a portion of
the purchase price of the acquisitions of the AT&T systems.

  On June 29, 2001, Mediacom Broadband and its wholly-owned subsidiary, Mediacom
Broadband Corporation, completed an offering of $400.0 million in aggregate
principal amount of 11% senior notes due July 2013.  Interest on the 11% senior
notes is payable semi-annually on January 15 and July 15 of each year,
commencing January 15, 2002.  The 11% senior notes were subject to a special
mandatory redemption if all of the acquisitions of the AT&T systems had not been
consummated on or prior to specified date, at a price equal to 101% of the
principal amount thereof, together with accrued and unpaid interest to the date
of redemption.  Upon the completion of the offering, the Company placed the net
proceeds of the offering of the 11% senior notes, along with the additional
amount of cash necessary to fund the special mandatory redemption, including the
accrued interest, in an escrow account, pending application of the escrow funds
by the Company for the payment of a portion of the purchase price for the
acquisitions of the AT&T systems and related fees and expenses, or in the event
of a special mandatory redemption of the 11% senior notes, the redemption price
in connection therewith.  The escrow funds were required to be invested in cash
or cash equivalents and are classified as restricted cash on the Company's
consolidated balance sheets as of June 30, 2001.  Pursuant to the escrow

                                       15
<PAGE>

agreement, the escrow funds were released to the Company on July 18, 2001, and
applied towards the purchase price for the acquisitions of the AT&T systems and
to pay related fees and expenses in connection with the completion of such
acquisitions on the same date.

  On July 18, 2001, the Company entered into a $1.4 billion senior secured
credit facility for the operating subsidiaries of Mediacom Broadband.  The
credit facility consists of a $600 million revolving credit facility, a $300
million tranche A term loan and a $500 million tranche B term loan.  The
revolving credit facility expires on March 31, 2010 and commitments under the
revolving credit facility will be reduced in quarterly installments beginning on
December 31, 2004.  The tranche A term loan matures on March 31, 2010 and the
tranche B term loan matures on September 30, 2010.  The term loans are payable
in quarterly installments beginning on September 30, 2004.  Interest on
outstanding revolving loans and the tranche A term loan is payable at either the
eurodollar rate plus a floating percentage ranging from 1.00% to 2.50% or the
base rate plus a floating percentage ranging from 0.25% to 1.50%.  Interest on
tranche B term loan is payable at either the eurodollar rate plus a floating
percentage ranging from 2.50% to 2.75% or the base rate plus a floating
percentage ranging from 1.50% to 1.75%.  Borrowings under this facility, in the
amount of $855.0 million, were used to fund a portion of the purchase price for
the acquisitions of the AT&T systems.

  After giving pro forma effect to the completion of the acquisitions of the
AT&T systems and the related financings noted above, the Company's total
indebtedness was approximately $2.77 billion as of June 30, 2001, and it had
unused credit commitments of approximately $1.1 billion under its subsidiaries'
revolving credit facilities.  On the same pro forma basis, the Company's
weighted average cost of indebtedness was approximately 7.6%.

  Although the Company has not generated earnings sufficient to cover fixed
charges, the Company has generated cash and obtained financing sufficient to
meet its debt service, working capital, capital expenditure and acquisition
requirements.  The Company expects that it will continue to be able to generate
funds and obtain financing sufficient to service the Company's obligations and
complete its future acquisitions.  There can be no assurance that the Company
will be able to obtain sufficient financing, or, if it were able to do so, that
the terms would be favorable to them.


Recent Accounting Pronouncements

  In June 1998, Statement of Financial Accounting Standards No. 133 ("SFAS
133"), "Accounting for Derivative Instruments and Hedging Activities," was
issued effective January 1, 2001.  This statement establishes the accounting and
reporting standards for derivatives and hedging activity.  Upon adoption of SFAS
133, all derivatives are required to be recognized in the statement of financial
position as either assets or liabilities and measured at fair value.  The
Company recorded an after tax charge of approximately $1.6 million as a change
in accounting principle in the first quarter of 2001.

  In June 2001, Statement of Financial Accounting Standards No. 142 ("SFAS
142"), "Accounting for Goodwill and other Intangible Assets," was issued
effective January 1, 2002.  This statement establishes that goodwill is no
longer subject to amortization over its useful life.  The new rule also states
that an acquired intangible assets must be separately recognized if it is
obtained through contractual or other legal rights, or if the asset can be sold,
licensed, transferred, exchanged or rented, regardless of the intent to do so.
The Company has not yet determined the impact that SFAS 142 may have on its
results of operations and the consolidated financial statements.


Inflation and Changing Prices

  The Company's systems' costs and expenses are subject to inflation and price
fluctuations.  Since changes in costs can be passed through to subscribers, such
changes are not expected to have a material effect on their results of
operations.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK


  In the normal course of business, the Company uses interest rate swap
agreements in order to fix the interest rate for the duration of the contract as
a hedge against interest rate volatility.  As of June 30, 2001, the Company had
interest rate exchange agreements (the "Swaps") with various banks pursuant to
which the interest rate on $170.0 million is fixed at a weighted average swap
rate of approximately 6.7%, plus the average applicable margin over the
Eurodollar Rate option under the Company's bank credit agreements.  Under the
terms of the Swaps, which expire from 2002 through 2004, the Company is exposed
to credit loss in the event of nonperformance by the other parties to the Swaps.
However, the Company does not anticipate nonperformance by the counterparties.
The Company would have paid approximately $3.0 million if it terminated the
Swaps, inclusive of accrued interest, at June 30, 2001.  The table below
provides information for the Company's long term debt.  See Note 5 to the
Company's consolidated financial statements.
