(1)  Statement of Accounting Presentation and Other Information

     Mediacom LLC ("Mediacom" and collectively with its subsidiaries, the
"Company"), a New York limited liability company, was formed in July 1995
principally to acquire and operate cable television systems.  As of June 30,
1999, the Company had acquired and was operating cable television systems in
fourteen states, principally Alabama, California, Florida, Kentucky, Missouri
and North Carolina.

     Mediacom Capital Corporation ("Mediacom Capital"), a New York corporation
wholly owned by Mediacom, was organized in March 1998 for the sole purpose of
acting as co-issuer with Mediacom of $200,000 aggregate principal amount of 8
1/2% senior notes due 2008 (the "8 1/2% Senior Notes") and of $125,000 aggregate
principal amount of 7 7/8% senior notes due 2011 (the "7 7/8% Senior Notes" and
collectively with the 8 1/2% Senior Notes, the "Senior Notes") (see Note 3).
Mediacom Capital has nominal assets and does not conduct operations of its own.
The Senior Notes are joint and several obligations of Mediacom and Mediacom
Capital, although Mediacom received all the net proceeds of the Senior Notes.

     The consolidated financial statements include the accounts of Mediacom and
its subsidiaries and have been prepared in accordance with the rules and
regulations of the Securities and Exchange Commission.  Accordingly, certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted.

     The consolidated financial statements as of June 30, 1999 and 1998 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, as amended (File
Nos. 333-57285-01 and 333-57285).  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, 1999.

(2)  Acquisitions

     The Company completed the undernoted acquisitions (the "Acquired Systems")
in 1998.  These acquisitions were accounted for using the purchase method of
accounting, and accordingly, the purchase price of these acquisitions has been
allocated to the assets acquired and liabilities assumed at their estimated fair
values at their respective date of acquisition.  The results of operations of
the Acquired Systems have been included with those of the Company since the
dates of acquisition.

     On January 9, 1998, the Company acquired the assets of a cable television
system serving approximately 17,200 basic subscribers in Clearlake, California
and surrounding communities (the "Clearlake System") for a purchase price of
$21,400.  The purchase price has been allocated based on an independent
appraisal as follows: approximately $5,973 to property, plant and equipment, and
approximately $15,427 to intangible assets.  Additionally, approximately $226 of
direct acquisition costs has been allocated to other assets.  In the first
quarter of 1998, the Company recorded acquisition reserves related to this
acquisition in the amount of approximately $370, which are included in accrued
expenses.  The acquisition of the Clearlake System and related closing costs and
adjustments were financed with borrowings under the Company's bank credit
facilities (see Note 3).

     On January 23, 1998, the Company acquired the assets of cable television
systems serving approximately 260,100 basic subscribers in various regions of
the United States (the "Cablevision Systems") for a purchase price of
approximately $308,200.  The purchase price has been allocated based on an
independent appraisal as follows: approximately $205,500 to property, plant and
equipment, and approximately $102,700 to intangible assets.  Additionally,
approximately $3,500 of direct acquisition costs has been allocated to other
assets. In the first quarter of 1998, the Company recorded acquisition reserves
related to this acquisition in the amount of approximately $3,750, which are
included in accrued expenses.  The acquisition of the Cablevision Systems and
related closing costs and adjustments were financed with equity contributions
and borrowings under the Company's bank credit facilities (see Note 3).

     On October 1, 1998, the Company acquired the assets of a cable television
system serving approximately 3,800 basic subscribers in Caruthersville, Missouri
(the "Caruthersville System") for a purchase price of $5,000.  The purchase
price has been allocated as follows: approximately $2,300 to property, plant and
equipment, and approximately $2,700 to intangible assets.  The acquisition of
the Caruthersville System and related closing costs and adjustments were
financed with borrowings under the Company's bank credit facilities (see Note
3).

     (a) On April 1, 1998, Mediacom and Mediacom Capital jointly issued $200,000
         aggregate principal amount of 8 1/2% Senior Notes due on April 15,
         2008.  The 8 1/2% Senior Notes are unsecured obligations of the
         Company, and the indenture for the 8 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 the Company.  Interest accrues at 8 1/2% per
         annum, beginning from the date of issuance and is payable semi-annually
         on April 15 and October 15 of each year.  The 8 1/2% Senior Notes may
         be redeemed at the option of Mediacom, in whole or part, at any time
         after April 15, 2003, at redemption prices decreasing from 104.25% of
         their principal amount to 100% in 2006, plus accrued and unpaid
         interest.

     (b) On February 26, 1999, Mediacom and Mediacom Capital jointly issued
         $125,000 aggregate principal amount of 7 7/8% Senior Notes due on
         February 15, 2011.  The 7 7/8% Senior Notes are unsecured obligations
         of the Company, and the indenture for the 7 7/8% 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 the Company.  Interest
         accrues at 7 7/8% per annum, beginning from the date of issuance and is
         payable semi-annually on February 15 and August 15 of each year,
         commencing on August 15, 1999.  The 7 7/8% Senior Notes may be redeemed
         at the option

       of Mediacom, in whole or part, at any time after February 15, 2006, at
       redemption prices decreasing from 103.938% of their principal amount to
       100% in 2008, plus accrued and unpaid interest.

(c)    On June 24, 1997, the Company entered into an eight and one-half year,
       $100,000 reducing revolver and term loan agreement (the "Western Credit
       Agreement"). On January 23, 1998, the Company entered into a separate
       eight and one-half year, $225,000 reducing revolver and term loan
       agreement (the "Southeast Credit Agreement" and together with the Western
       Credit Agreement, the "Bank Credit Agreements"). By separate amendments
       dated as of January 26, 1999 to each of the Bank Credit Agreements, the
       term loans were converted into additional revolving credit loans. At June
       30, 1999, the aggregate commitments under the Bank Credit Agreements were
       $321,000. The Bank Credit Agreements are non-recourse to Mediacom and
       have no cross-default provisions relating directly to each other. The
       reducing revolving credit lines under the Bank Credit Agreements make
       available a maximum commitment amount for a period of up to eight and
       one-half years, which is subject to quarterly reductions, beginning
       September 30, 1998, ranging from 0.21% to 11.58% of the original
       commitment amount of the reducing revolver. The Bank Credit Agreements
       require mandatory reductions of the reducing revolver credit lines from
       excess cash flow, as defined, beginning December 31, 1999. The Bank
       Credit Agreements provide for interest at varying rates based upon
       various borrowing options and the attainment of certain financial ratios,
       and for commitment fees of 3/8% to 1/2% per annum on the unused portion
       of available credit under the reducing revolver credit lines. The average
       interest rate on outstanding debt under the Bank Credit Agreements was
       6.3% and 6.9% for the three months ended June 30, 1999 and December 31,
       1998, respectively, before giving effect to the interest rate swap
       agreements discussed below.

       The Bank Credit Agreements require the Company to maintain compliance
       with certain financial covenants including, but not limited to, the
       leverage ratio, the interest coverage ratio, the fixed charge coverage
       ratio and the pro forma debt service coverage ratio, as defined therein.
       The Bank Credit Agreements also require the Company to maintain
       compliance with other covenants including, but not limited to,
       limitations on mergers and acquisitions, consolidations and sales of
       certain assets, liens, the incurrence of additional indebtedness, certain
       restrictive payments, and certain transactions with affiliates.  The
       Company was in compliance with all covenants of its Bank Credit
       Agreements as of June 30, 1999.

       The Bank Credit Agreements are secured by Mediacom's pledge of all its
       ownership interests in the subsidiaries and a first priority lien on all
       the tangible and intangible assets of the operating subsidiaries, other
       than real property in the case of the Southeast Credit Agreement.  The
       indebtedness under the Bank Credit Agreements is guaranteed by Mediacom
       on a limited recourse basis to the extent of its ownership interests in
       the operating subsidiaries.  At June 30, 1999, the Company had $260,000
       of unused bank commitments under the Bank Credit Agreements, all of which
       could have been borrowed by the operating subsidiaries for purposes of
       distributing such borrowed proceeds to Mediacom under the most
       restrictive covenants.

       As of June 30, 1999, the Company had entered into interest rate exchange
       agreements (the "Swaps") with various banks pursuant to which the
       interest rate on $50,000 is fixed at a weighted average swap rate of
       approximately  6.2%, plus the average applicable margin over the
       Eurodollar Rate option under the Bank Credit Agreements.  Under the terms
       of the Swaps, which expire from 2000 through 2002, 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. During the first quarter of 1999, the net proceeds from
       the offering of the 7 7/8% Senior Notes, in the amount of approximately
       $121,900, were used to repay a substantial portion of outstanding debt
       under the Bank Credit Agreements.  As a result of this repayment of
       floating rate bank debt, approximately $19,000 of the $50,000 of Swaps
       outstanding as of June 30, 1999, no longer qualify as hedge instruments.
       Accordingly, such Swaps have

       been marked to market as of June 30, 1999, with a fair value of
       approximately $135 which is included in accrued expenses. The related
       effect to the consolidated statement of operations was approximately
       $619, which is included in other income for the three months ended June
       30, 1999 and $135, which is included in other expenses for the six months
       ended June 30, 1999.

  (d)  In connection with an acquisition completed in 1996, certain
       subsidiaries of Mediacom issued to the seller an unsecured senior
       subordinated note (the "Seller Note") in the amount of $2,800, with a
       final maturity of June 28, 2006.  Interest is deferred throughout the
       term of the Seller Note and is payable at maturity or upon prepayment.
       For the five-year period ending June 28, 2001, the annual interest rate
       is 9.0%.  After the initial five-year period, the annual interest rate
       increases to 15.0%, with an interest clawback for the first five years.
       After the initial seven-year period, the interest rate increases to
       18.0%, with an interest clawback for the first seven years. There are no
       penalties associated with prepayment of this note.

       The Seller Note agreement contains a debt incurrence covenant limiting
       the ability of the Company to incur additional indebtedness under the
       Western Credit Agreement.  The Seller Note is subordinated and junior in
       right of payment to all senior obligations of certain subsidiaries, as
       defined in the Western Credit Agreement.

     All debt outstanding as of June 30, 1999, matures after December 31, 2004.

(4)  Commitments and Contingencies

     Pursuant to the Cable Television Consumer Protection and Competition Act of
1992, the Federal Communications Commission (the "FCC") adopted comprehensive
regulations governing rates charged to subscribers for basic cable and cable
programming services.  The FCC's authority to regulate the rates charged for
cable programming services expired on March 31, 1999.  Basic cable rates must be
set using a benchmark formula.  Alternatively, a cable operator  can  attempt
to  establish  higher rates  through  a  cost-of-service  showing.  The  FCC
has  also  adopted regulations that permit qualifying small cable operators to
justify their regulated rates using a simplified rate-setting methodology.  This
methodology almost always results in rates which exceed those produced by the
cost-of-service rules applicable to larger cable television operators.
Approximately 70% of the basic subscribers served by the Company's cable
television systems are covered by such FCC rules.  Once rates for basic cable
service have been established pursuant to one of these methodologies, the rate
level can subsequently be adjusted only to reflect changes in the number of
regulated channels, inflation, and increases in certain external costs, such as
franchise and other governmental fees, copyright and retransmission consent
fees, taxes, programming costs and franchise-related obligations.  FCC
regulations also govern the rates which can be charged for the lease of customer
premises equipment and for installation services.

     As a result of such legislation and FCC regulations, the Company's basic
cable service rates and its equipment and installation charges (the "Regulated
Services") are subject to the jurisdiction of local franchising authorities.
The Company believes that it has complied in all material respects with the rate
regulation provisions of the federal law.  However, the Company's rates for
Regulated Services are subject to review by the appropriate franchise authority
if it is certified by the FCC to regulate basic cable service rates.  If, as a
result of the review process, the Company cannot substantiate the rates charged
by its cable television systems for Regulated Services, the Company could be
required to reduce its rates for Regulated Services to the appropriate level and
refund the excess portion of rates received for up to one year prior to the
implementation of any increase in rates for Regulated Services.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         (All dollar amounts in 000's)
                                  (Unaudited)


     The Company's agreements with franchise authorities require the payment of
fees of up to 5% of annual revenues.  Such franchises are generally nonexclusive
and are granted by local governmental authorities for a specified term of years,
generally for periods of up to fifteen years.

     On April 29, 1999, a bank issued two irrevocable letters of credit in the
aggregate amount of $30,000 in favor of the seller of the Triax Systems (defined
below) to secure the Company's performance under the related definitive
agreement.

(5)  FASB 131 - Disclosure about Segments of an Enterprise and Related
     Information

     As of December 31, 1998, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 131, "Disclosure about Segments of an Enterprise
and Related Information".  This statement requires the Company to report segment
financial information consistent with the presentations made to the Company's
management for decision-making purposes.  All revenues of the Company are
derived solely from cable television operations and related activities.  The
decision making of the Company's management is based primarily on the impact of
capital and operational resource allocations on the Company's consolidated
system cash flow (defined as operating income (loss) before management fee
expense, and depreciation and amortization). The Company's management evaluates
such factors as the bandwidth capacity and other cable plant characteristics,
the offered programming services, and the customer rates, when allocating
capital and operational resources.  The Company's consolidated system cash flow
for the three months ended June 30, 1999 and 1998 was approximately $18,527, and
$16,246, respectively, and for the six months ended June 30, 1999 and 1998 was
approximately $35,501 and $27,064, respectively.

(6)  Recent Developments

     On April 29, 1999, the Company entered into a definitive agreement to
acquire the cable television systems owned by Triax Midwest Associates, L.P.
(the "Triax Systems") for a purchase price of $740,000. The Triax Systems serve
approximately 341,500 basic subscribers in Arizona, Illinois, Indiana, Iowa,
Michigan, Minnesota, Ohio and Wisconsin. Closing is expected in the fourth
quarter of 1999 and is subject to regulatory and other customary approvals.

     On May 26, 1999, the Company entered into a definitive agreement to
purchase the outstanding capital stock of Zylstra Communications Corporation
(the "Zylstra Systems") for a purchase price of $21,500. The Zylstra Systems
serve approximately 14,000 basic subscribers in Iowa, Minnesota, and South
Dakota. Closing is expected in the second half of 1999 and is subject to
regulatory and other customary approvals.

     On July 2, 1999, the Company signed an exclusive agreement, subject to
completion of final documents, with SoftNet Systems, Inc. ("SoftNet"), a high-
speed broadband Internet access and content services company, to deploy
SoftNet's high speed Internet access services throughout the Company's cable
television systems.  In addition to a revenue sharing arrangement, the Company
will receive 3.5 million shares of SoftNet's common stock as compensation for
SoftNet's exclusive long-term rights to deliver high-speed Internet access
services to the Company's customers.  Under the terms of this agreement, over a
period of three years the Company is required to upgrade its cable network to
provide two-way communications capability in cable systems passing 900,000
homes, including the Triax Systems and Zylstra Systems, and make available such
homes to SoftNet.  There can be no assurance that the final documents for the
transaction with SoftNet will be completed.

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

Introduction

     The following discussion of the financial condition and results of
operations of the Company, the description of the Company's business as well as
other sections of this Form 10-Q contain certain forward-looking statements.
The Company's actual results could differ materially from those discussed herein
and its current business plans could be altered in response to market conditions
and other factors beyond the Company's control.

     Adjusted EBITDA represents operating income (loss) before depreciation and
amortization.  Adjusted 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, as determined in accordance with generally accepted
accounting principles.  Adjusted EBITDA is included herein because the Company's
management believes that Adjusted 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 on the basis of
operating performance, leverage and liquidity.  In addition, the primary debt
instruments of the Company contain certain covenants, compliance with which is
measured by computations similar to determining Adjusted EBITDA.  The Company's
definition of Adjusted EBITDA may not be identical to similarly titled measures
reported by other companies.

     Mediacom was founded in July 1995 principally to acquire, operate and
develop cable television systems in selected non-metropolitan markets of the
United States.  The Company's business strategy is to: (i) acquire
underperforming and undervalued cable television systems primarily in non-
metropolitan markets,  as well as related telecommunications businesses; (ii)
invest in the development of a state-of-the-art technological platform for
delivery of broadband video and other services to its customers; (iii) provide
superior customer service; and (iv) deploy a flexible financing strategy to
complement the Company's growth objectives and operating plans.

     The Company commenced operations in March 1996 with the acquisition of its
first cable television system.  As of June 30, 1999, the Company had completed
nine acquisitions of cable television systems that on such date passed
approximately 523,000 homes and served approximately 355,800 basic subscribers.
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.

Results of Operations

     The following historical information includes the results of operations of
the Clearlake System (acquired on January 9, 1998), the Cablevision Systems
(acquired on January 23, 1998), and the Caruthersville System (acquired on
October 1, 1998) (collectively, the "Acquired Systems") only for that portion of
the respective period that such cable television systems were owned by the
Company.  See Note 2 to the Company's consolidated financial statements for a
detailed description of the Company's acquisitions in 1998.

  Three Months Ended June 30, 1999 Compared to Three Months Ended June 30, 1998

     Revenues increased 11.9% to approximately $38.2 million for the three
months ended June 30, 1999 as compared to $34.1 million for the three months
ended June 30, 1998, primarily as a result of:

     .  including the results of operations of the Caruthersville System in the
        1999 period;

     .  an increase in the average monthly basic service rate of $2.89 per basic
        subscriber; and

     .  internal basic subscriber growth of 2.0%, excluding the acquisition of
        the Caruthersville System.

     Average monthly revenue per basic subscriber increased to $35.75 for the
three months ended June 30, 1999, from $32.89 for the corresponding period of
1998.  At June 30, 1999, the Company served approximately 355,800 basic
subscribers compared to approximately 345,000 basic subscribers at June 30,
1998.

                                       12
<PAGE>

     Service costs increased 6.1% to approximately $12.4 million for the three
months ended June 30, 1999, as compared to approximately $11.6 million for the
three months ended June 30, 1998. The Caruthersville System accounted for
approximately 28.6% of the total increase. Excluding the Caruthersville System,
these costs increased by approximately $571,000 primarily as a result of
increased programming costs, additional programming carried by the Company's
systems and increased employee expenses. As a percentage of revenues, service
costs were 32.3% for the three months ended June 30, 1999, as compared with
34.1% for the three months ended June 30, 1998.

     Selling, general and administrative expenses increased 17.0% to
approximately $7.3 million for the three months ended June 30, 1999, as compared
to approximately $6.2 million for the three months ended June 30, 1998.  The
Caruthersville System accounted for approximately 10.6% of the total increase.
Excluding the Caruthersville System, these costs increased by approximately
$983,000 primarily as a result of increased marketing costs associated with the
promotion of new programming services and higher personnel expenses.  As a
percentage of revenues, selling, general and administrative expenses were 19.1%
for the three months ended June 30, 1999, as compared with 18.3% for the three
months ended June 30, 1998.

     Management fee expense increased 22.1% to approximately $1.9 million for
the three months ended June 30, 1999, from approximately $1.6 million in the
comparable 1998 period, due to the higher revenues generated in the 1999 period.

     Depreciation and amortization expense increased 29.9% to approximately
$21.0 million for the three months ended June 30, 1999, from approximately $16.2
million in the comparable 1998 period.  This increase was substantially due to
the Company's acquisitions in 1998 and additional capital expenditures
associated with the upgrade of the Company's systems.

     Interest expense, net, increased 4.3% to approximately $7.0 million for the
three months ended June 30, 1999, from approximately $6.7 million for the three
months ended June 30, 1998.  This increase was substantially due to higher
average debt outstanding during the 1999 period.  Other income was approximately
$259,000 for the three months ended June 30, 1999 as compared to other expense
of approximately $228,000 for the three months ended June 30, 1998.  This change
was principally due to a decrease in the fair value of interest rate swaps.

     Due to the factors described above, the Company generated a net loss of
approximately $11.2 million for the three months ended June 30, 1999, compared
to a net loss of approximately $8.5 million for the three months ended June 30,
1998.

     Adjusted EBITDA increased 13.2% to approximately $16.6 million for the
three months ended June 30, 1999, from approximately $14.7 million for the three
months ended June 30, 1998.  This increase was substantially due to the reasons
noted above.  Adjusted EBITDA as a percentage of revenues increased to 43.5% for
the three months ended June 30, 1999, from 43.0% for the three months ended June
30, 1998.  On a pro forma basis, assuming the Acquired Systems were owned and
operated by the Company as of January 1, 1998, Adjusted EBITDA increased by
12.1% for the three months ended June 30, 1999 over the comparable period in
1998.

  Six Months ended June 30, 1999 Compared to Six Months Ended June 30, 1998

     Revenues increased 23.5% to approximately $74.2 million for the six months
ended June 30, 1999, as compared to approximately $60.1 million for the six
months ended June 30, 1998, primarily as a result of:

     .    including the results of operations of the Acquired Systems for the
          full six month period in 1999;

     .    an increase in the average monthly basic service rate of $2.98 per
          basic subscriber; and

     .    internal basic subscriber growth of 2.0%, excluding the acquisition of
          the Caruthersville System.

                                       13
<PAGE>

     Service costs increased 12.6% to approximately $24.2 million for the six
months ended June 30, 1999, as compared to approximately $21.5 million for the
six months ended June 30, 1998.  The Acquired Systems accounted for
substantially all of this increase.  As a percentage of revenues, service costs
were 32.6% for the six months ended June 30, 1999, as compared with 35.7% for
the six months ended June 30, 1998.

     Selling, general and administrative expenses increased 25.7% to
approximately $14.5 million for the six months ended June 30, 1999, from
approximately $11.5 million for the six months ended June 30, 1998.  The
Acquired Systems accounted for approximately 43.3% of the total increase.
Excluding the Acquired Systems, these costs increased by approximately $1.7
million primarily as a result of increased marketing costs associated with the
promotion of new programming services and increased personnel expenses.  As a
percentage of revenues, selling, general and administrative expenses were 19.6%
for the six months ended June 30, 1999 as compared with 19.2% for the six months
ended June 30, 1998.

     Management fee expense increased 29.0% to approximately $3.6 million for
the six months ended June 30, 1999, from approximately $2.8 million in the
comparable 1998 period, due to the higher revenues generated in the 1999 period.

     Depreciation and amortization expense increased 51.1% to approximately
$41.4 million for the six months ended June 30, 1999, from approximately $27.4
million in the comparable 1998 period.  This increase was substantially due to
the Company's acquisitions in 1998 and additional capital expenditures
associated with the upgrade of the Company's systems.

     Interest expense, net, increased 14.1% to approximately $13.4 million for
the six months ended June 30, 1999, from approximately $11.7 million for the six
months ended June 30, 1998.  This increase was substantially due to higher
average debt outstanding during the 1999 period as a result of the debt incurred
in connection with the purchase of the Acquired Systems.  Other expenses
decreased 79.4% to approximately $734,000 for the six months ended June 30,
1999, from approximately $3.6 million for the six months ended June 30, 1998.
This decrease was principally due to acquisition fees incurred in the 1998
period in connection with the acquisition of the Clearlake System and the
Cablevision Systems.

     Due to the factors described above, the Company generated a net loss of
approximately $23.6 million for the six months ended June 30, 1999, compared to
a net loss of approximately $18.4 million for the six months ended June 30,
1998.

     Adjusted EBITDA increased 31.4% to approximately $31.9 million for the six
months ended June 30, 1999, from approximately $24.3 million for the six months
ended June 30, 1998.  This increase was substantially due to the inclusion of
the results of operations of the Acquired Systems for the full six-month period
in 1999, and the other factors described above.  Adjusted EBITDA as a percentage
of revenues increased to 43.0% for the six months ended June 30, 1999, from
40.4% for the six months ended June 30, 1998. On a pro forma basis, assuming the
Acquired Systems were owned and operated by the Company as of January 1, 1998,
Adjusted EBITDA increased 17.6% for the six months ended June 30, 1999 over the
comparable period in 1998.

Liquidity and Capital Resources

     The cable television business is a capital-intensive business that
generally requires financing for the upgrade, expansion and maintenance of the
technical infrastructure.  In addition, the Company has pursued, and will
continue to pursue, a business strategy that includes selective acquisitions.
The Company has funded its working capital requirements, capital expenditures
and acquisitions through a combination of internally generated funds, long-term
borrowings and equity contributions.  The Company intends to continue to finance
such expenditures through the same sources.

                                       14
<PAGE>

     During the third quarter of 1998, the Company modified its previously
disclosed five-year capital improvement program by accelerating its planned
completion date to June 30, 2000.  This accelerated program will enable the
Company to deploy digital cable television technology and cable modem service
earlier and more widespread than previously planned, beginning in 1999.  Upon
completion of the capital improvement program in June 30, 2000, the Company
anticipates that over 85% of its existing customer base will be served by cable
television systems with 550-750MHz bandwidth capacity.

     As a result of these strategic initiatives, total capital expenditures
(other than those related to acquisitions) are budgeted at $66.0 million for
1999, of which approximately $35.9 million was spent during the six months ended
June 30, 1999.  The Company intends to utilize cash generated from operations
and its available unused credit commitments under its subsidiary bank credit
facilities, as described below, to fund its capital expenditures budget.

     From the Company's commencement of operations in March 1996 through
December 31, 1997, the Company invested approximately $97.8 million (before
closing costs) to acquire cable television systems serving approximately 66,700
basic subscribers as of June 30, 1999.  In 1998, the Company invested
approximately $334.6 million (before closing costs) to acquire cable television
systems serving approximately 289,100 basic subscribers as of June 30, 1999.  In
the aggregate, the Company has invested approximately $432.4 million (before
closing costs) to acquire its cable television systems serving approximately
355,800 basic subscribers as of June 30, 1999.

     Mediacom is a limited liability company that serves as the holding company
for its various subsidiaries, each of which is also a limited liability company.
To date, the Company's financing strategy has been to raise equity from its
members and issue public long-term debt at the holding company level, while
utilizing its subsidiaries to access debt capital, principally in the commercial
bank market, through two stand-alone borrowing groups.  The Company believes
that this financing strategy is beneficial because it broadens the Company's
access to various debt markets, enhances its flexibility in managing the
Company's capital structure, reduces the overall cost of debt capital, and
permits the Company to maintain a substantial liquidity position in the form of
unused and available bank credit commitments.

     As of June 30, 1999, in order to finance its working capital requirements,
capital expenditures and acquisitions and to provide liquidity for future
capital needs, the Company had completed the following financing arrangements:

     .   $100.0 million subsidiary bank credit agreement expiring in
         September 2005;

     .   $225.0 million subsidiary bank credit agreement expiring in
         September 2006;

     .   $2.8 million original principal amount seller note issued in connection
         with the acquisition of a cable television system;

     .   $200.0 million offering of 8 1/2% senior notes in April 1998;

     .   $125.0 million offering of 7 7/8% senior notes in February 1999; and

     .   $125.0 million of equity capital contributed by Mediacom's members.

     As of June 30, 1999, the Company had entered into interest rate swap
agreements to hedge a notional amount of $50.0 million of borrowings under the
bank credit agreements, which expire from 2000 through 2002.  For the three
months ended June 30, 1999, the weighted average interest rate on all
indebtedness outstanding under the Company's credit facilities was approximately
6.3%, before giving effect to the aforementioned interest rate swap agreements.

     As of June 30, 1999, a bank had issued two irrevocable letters of credit
under the Company's existing bank credit agreements in the aggregate amount of
$30.0 million (the "Acquisition Deposit") in favor of the seller of the Triax
Systems to secure the Company's performance under the related agreement to
acquire these systems.

     As of June 30, 1999, the Company had $260.0 million of unused credit
commitments, all of which could have been borrowed and distributed to the
Company under the most restrictive covenants in the bank credit agreements. Debt
leverage and interest coverage ratios are commonly used in the cable television
industry to measure liquidity and financial condition.  For the three-month
period ended June 30, 1999, the debt leverage ratio (defined as total debt at
the end of the period, exclusive of the Acquisition Deposit, divided by
annualized Adjusted EBITDA for the period) was 5.41x and the interest coverage
ratio (defined as Adjusted EBITDA divided by interest expense, net for the
period ) was 2.37x.

     On April 29, 1999, the Company signed a definitive agreement to purchase
the cable television systems owned by Triax Midwest Associates, L.P. (the "Triax
Systems") for $740.0 million, before closing costs and adjustments.  As of June
30, 1999, the Triax Systems served approximately 341,500 basic subscribers in
eight states, principally Illinois, Indiana, Iowa and Minnesota.  The Company
anticipates closing this transaction in the fourth quarter of 1999, subject to
regulatory and other customary approvals.

     On May 26, 1999, the Company signed a definitive agreement to purchase all
of the outstanding stock of Zylstra Communications Corporation (the "Zylstra
Systems") for $21.5 million, before closing costs and adjustments.  As of June
30, 1999, the Zylstra Systems served approximately 14,000 basic subscribers in
Iowa, Minnesota and South Dakota.  The Company anticipates closing this
transaction in the second half of 1999, subject to regulatory and other
customary approvals.

     The Company expects to spend $761.5 million, before adjustments and closing
costs, to acquire the Triax Systems and Zylstra Systems.  In order to finance
these acquisitions and to provide liquidity for future capital needs, the
Company plans to establish two new subsidiary credit facilities in an aggregate
amount of $1.0 billion.  The first facility would replace and combine the
existing subsidiary bank credit facilities and provide a $400.0 million
revolving credit facility and a $100.0 million term loan. The Company has
received commitments from lenders for the $400.0 million revolving credit
facility and is currently seeking commitments for the $100.0 million term loan.
These commitments are subject to numerous conditions, including completion of
documentation acceptable to the lenders. It is anticipated that the second
facility would provide for an additional $500.0 million in credit commitments.
The Company also expects to receive $10.5 million of new capital commitments
from its members. The Company anticipates that these financing arrangements will
be completed prior to closing the acquisition of the Triax Systems.

     The Company is regularly presented with opportunities to acquire cable
television systems that are evaluated on the basis of the Company's acquisition
strategy.  Although the Company presently does not have any definitive
agreements to acquire or sell any of its cable television systems, other than
the definitive agreements to acquire the Triax Systems and Zylstra Systems, from
time to time it negotiates with prospective sellers to acquire additional cable
television systems.  These potential acquisitions are subject to the negotiation
and completion of definitive documentation, which will include customary
representations and warranties and will be subject to a number of closing
conditions.  No assurance can be given that such definitive documents will be
entered into or that, if entered into, the acquisitions will be consummated.

     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 expenditures and acquisition
requirements.  The Company expects that it will continue to be able to generate
funds and obtain financing sufficient to service its obligations and complete
its pending acquisitions.  There can be no assurance that the Company will be
able to complete the financing arrangements described above, or, if the Company
was able to do so, that the terms would be favorable to the Company.

Recent Accounting Pronouncements

     In 1998, Statement of Financial Accounting Standards No. 133, "Accounting
for Derivative Instruments and Hedging Activities", ("SFAS 133") was issued.
SFAS 133 establishes accounting and reporting standards requiring that every
derivative instrument be recorded in the balance sheet as either an asset or
liability measured at its fair value.  The Company will adopt SFAS 133 in fiscal
2001, but has not quantified the impact or not yet determined the timing or
method of the adoption.

Inflation and Changing Prices

     The Company's costs and expenses are subject to inflation and price
fluctuations.  However, because changes in costs are generally passed through to
subscribers, such changes are not expected to have a material effect on the
Company's results of operations.

Year 2000

     The Company has formed a Year 2000 project management team responsible for
overseeing, coordinating and reporting on the Year 2000 remediation efforts.
The Company has implemented a company-wide effort to assess and remediate its
computer systems, related software and equipment.  This effort will also help to
ensure such systems, software and equipment can recognize, process and store
information in the year 2000 and thereafter.  Such Year 2000 remediation efforts
include an assessment of the most critical systems, such as customer service and
billing systems, headend facilities, business support operations, and other
equipment and facilities.  The Company is also verifying the Year 2000 readiness
of its significant suppliers and vendors.

     As of June 30, 1999, the Company's assessment and remediation were
substantially complete, and testing and implementation are 50% complete, with
final completion expected in the fourth quarter of 1999.

     The project management team has also identified the Company's most critical
supplier/vendor relationships and has instituted a verification process to
determine the vendors' Year 2000 readiness.  Such verification includes
reviewing vendors' test and other data and engaging in regular communications
with vendors' Year 2000 teams.  The Company is currently conducting tests to
validate the Year 2000 compliance of certain critical products and services.

     The completion dates set forth above are based on current expectations.
However, due to the uncertainties inherent in Year 2000 remediation, no
assurances can be given as to whether such projects will be completed on such
dates.

     The Company is in the process of acquiring certain cable television
systems, and it is monitoring their Year 2000 remediation efforts.  However, the
Company cannot determine at this time the materiality of information technology
and non-information technology issues, if any, relating to the Year 2000 problem
affecting those cable television systems.  The Company is in the process of
including these pending acquisitions in its Year 2000 program and is not
currently aware of any likely material Year 2000 problems.

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, 1999, the Company had
interest rate exchange agreements (the "Swaps") with various banks pursuant to
which the interest rate on $50.0 million is fixed at a weighted average swap
rate of approximately 6.2%, plus the average applicable margin over the
Eurodollar Rate option under the Company's bank credit facilities.  Under the
terms of the Swaps, which expire from 2000 through 2002, 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.
On February 26, 1999, Mediacom and Mediacom Capital jointly issued $125,000
aggregate principal amount of 7 7/8% Senior Notes due on February 15, 2011.
Interest accrues at 7 7/8% per annum, beginning from the date of issuance and is
payable semi-annually.  The net proceeds from the offering of the 7 7/8% senior
notes, in the amount of approximately $121.9 million, were used to repay a
substantial portion of outstanding debt under the bank credit agreements.  As a
result of the repayment of floating rate bank debt, $19.0 million of the $50.0
million of Swaps outstanding as of June 30, 1999, no longer qualify as hedge
instruments.  Accordingly, such Swaps have been marked to market as of June 30,
1999 and had a fair value of approximately $135,000 which is included in accrued
expenses. The related effect to the consolidated statement of operations was
approximately $619,000 which is included in other income for the three months
ended June 30, 1999 and approximately $135,000 which is included in other
expenses for the six months ended June 30, 1999.
