1.   ORGANIZATION AND BASIS OF PRESENTATION

     Renaissance Media Group LLC ("Group") was formed on March 13, 1998 by
Renaissance Media Holdings LLC ("Holdings").  Holdings is owned by Morgan
Stanley Capital Partners III, L.P. ("MSCP III"), Morgan Stanley Capital
Investors, L.P. ("MSCI"), MSCP III 892 Investors, L.P. ("MSCP Investors" and,
collectively, with its affiliates, MSCP III and MSCI and their respective
affiliates, the "Morgan Stanley Entities"), Time Warner (as hereinafter defined)
and the Management Investors (as hereinafter defined).  Holdings formed
Renaissance Media Capital Corporation on March 12, 1998.  On March 20, 1998,
Holdings contributed to Group its membership interests in two wholly-owned
subsidiaries; Renaissance Media (Louisiana) LLC ("Louisiana") and Renaissance
Media (Tennessee) LLC ("Tennessee"), which were formed on January 7, 1998.
Louisiana and Tennessee acquired a 76% interest and 24% interest, respectively,
in Renaissance Media LLC ("Media") from Morgan Stanley Capital Partners III,
Inc. ("MSCP"), on February 13, 1998 at the same nominal amount through an
acquisition of entities under common control accounted for as if it were a
pooling of interests.  As a result, Media became a subsidiary of Group and
Holdings. Group and its aforementioned subsidiaries are collectively referred to
as the "Company".  On April 9, 1998, the Company acquired (the "Acquisition")
six cable television systems (the "Systems") from TWI Cable, Inc. ("TWI Cable"),
a subsidiary of Time Warner Inc. ("Time Warner").  See Note 3.  Prior to this
Acquisition, the Company had no operations other than start-up related
activities.

     The accompanying financial statements have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles.  The interim financial statements
are unaudited but include all adjustments, which are of normal recurring nature
that the Company considers necessary for a fair presentation of the financial
position and the results of operations and cash flows for such period.
Operating results of interim periods are not necessarily indicative of results
for a full year.  For further information, refer to Company's Amendment No. 3 to
Registration Statement on Form S-1 and S-4 (Registration No. 333-56679), for
additional disclosures, and information regarding the formation of the Company.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     New Accounting Standards

     During fiscal 1997 and 1998, the Financial Accounting Standards Board
("FASB") issued Statement No. 130, "Reporting Comprehensive Income" ("FAS 130"),
Statement No. 131, "Disclosures about Segments of an Enterprise and Related
Information" ("FAS 131"), Statement No. 132, "Employers' Disclosures about
Pension and Other Post-retirement Benefits" ("FAS 132"), and Statement No. 133,
" Accounting for Derivation Instruments and Hedging Activities" ("FAS 133").
FAS 130 establishes standards for reporting and display of comprehensive income
and its components (revenue, expenses, gains and losses) in a full set of
financial statements.

     The Company adopted FAS 130 as of the second quarter of 1998.  FAS 131
requires disclosure of financial and descriptive information about an entity's
reportable operating segments under the "management approach" as defined in such
Statement.  The Company will adopt FAS 131 as of December 31, 1998.  FAS 132
standardizes the disclosure requirements for pensions and other post-retirement
benefits.  The Company adopted FAS 132 as of the second quarter of 1998.  FAS
133 provides a comprehensive and consistent standard for the recognition and
measurement of derivatives and hedging activities.  The Company will adopt FAS
133 as of January 1, 2000.  The adoption of FAS 130 and FAS 132 had no effect on
the financial statements.  The impact of the adoption of the remaining
aforementioned standards on the Company's financial statements is not expected
to be material.

     Principles of Consolidation

     The consolidated financial statements of the Company include the accounts
of the Company and its wholly owned subsidiaries.  Significant intercompany
accounts and transactions have been eliminated.

     Cash and Cash Equivalents

     Cash and cash equivalents include cash and investments in short-term,
highly liquid securities, which have maturities when purchased of three months
or less.

     Property, Plant and Equipment

     Property, plant and equipment are stated at cost.  Replacements, renewals
and improvements are capitalized.  Maintenance and repairs are charged to
expense as incurred.  Depreciation of property, plant and equipment is provided
using the straight-line method over the following estimated service lives:

     Buildings..........................................     40 years
     Distribution plant.................................     3-10 years
     Other equipment and leasehold improvements.........     3-20 years

     Cable Television Franchises and Intangible Assets

     Cable television franchises include costs incurred to obtain franchise
agreements.  Intangible assets include goodwill, deferred financing and other
intangible assets.  Cable television franchises and intangible assets are
amortized using the straight-line method over the following estimated useful
lives:

     Cable television franchises........................     15 years
     Goodwill...........................................     25 years
     Deferred financing and other intangible assets.....     2-10 years

     The Company periodically reviews the carrying value of its long-lived
assets, including property, plant and equipment and intangible assets, whenever
events or changes in circumstances indicate that the carrying value may not be
recoverable.  To the extent the estimated future cash inflows attributable to
the asset, less estimated future cash outflows, is less than the carrying
amount, an impairment loss is recognized to the extent that the carrying value
of such asset is greater than its fair value.

     Revenue Recognition

     Cable television service revenue is recognized in the month service is
provided to customers.  Advance payments on cable services to be rendered are
recorded as subscriber prepayments.  Advertising revenue is recognized in the
period in which the advertising commercials are aired.

     Estimates Used in Financial Statement Presentation

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period.  Actual results could differ from those estimates.

3.   ACQUISITIONS

     TWI Cable

     On April 9, 1998, the Company acquired six cable television systems from
TWI Cable.  The systems are clustered in southern Louisiana, western Mississippi
and western Tennessee.  This Acquisition represented the first acquisition by
the Company.  The purchase price for the systems was $309,500 which was paid as
follows:  TWI Cable received $300,000 in cash, inclusive of an escrow deposit of
$15,000, and a $9,500 (9,500 units) equity interest in Renaissance Media
Holdings LLC, the parent company of Group.  In addition to the purchase price,
the Company incurred approximately $1,300 in transaction costs, exclusive of
financing costs.

     The 9,500 units issued to TWI Cable as equity represent an 8.7% interest in
Holdings, determined by dividing the TWI Cable interests of 9,500 units by the
total units outstanding of Holdings of 108,600.  TWI Cable's interest in
Holdings is as a minority member with rights to appoint one board
representative, and TWI Cable has economic interests in Holdings equal to its
ownership percentage on the same basis as the other members of Holdings.  In
accordance with the Limited Liability Company Agreement of Holdings, TWI Cable
is not required to make any further equity contribution to Holdings and its
ability to sell or otherwise dispose of its interests in Holdings is limited.
Holdings was formed to consummate the Acquisition and had no assets prior to
this transaction.

     The Acquisition was accounted for using the purchase method of accounting
and, accordingly, results of operations are reported from the date of the
Acquisition (April 9, 1998).  The excess of the purchase price over the
estimated fair value of the tangible assets acquired ($244,300) has been
allocated to Cable television franchises and goodwill in the amount of $235,700
and $8,600, respectively.  The appraisal of the acquired assets is not yet
complete, thus the allocation of the purchase price is subject to change,
although management currently does not expect any material adjustment to such
allocation.

     DEFFNER CABLE

Credit Agreement provides for interest at varying rates based upon various
borrowing options and the attainment of certain financial ratios and for
commitment fees of 1/2 % on the unused portion of the revolver. The effective

                                                     ======== 

   As required by the Credit Agreement, Renaissance Media purchased an interest
rate cap agreement from Morgan Stanley Capital Services Inc. an affiliate of
MSCP. The agreement effectively fixed or set a maximum LIBOR rate of 7.25% on
bank debt borrowing up to $100,000 through December 1999.

   The Credit Agreement and the Indenture pursuant to which the Notes were
issued contain restrictive covenants on the Company and subsidiaries regarding
additional indebtedness, investment guarantees, loans, acquisitions, dividends
and merger or sale of the subsidiaries and require the maintenance of certain
financial ratios.

5. TAXES

   Group and Media are limited liability companies and are not subject to
federal or state income tax. Any income earned by these entities will be taxed
to their respective members.

   Louisiana and Tennessee have elected to be treated as corporations for
federal income tax purposes and have not recorded any tax benefit for their
losses as the realization of these losses by reducing future taxable income in
the carry forward period is uncertain at this time. The provision for income
taxes reflected in the consolidated statement of operations is for Tennessee
Corporate Franchise taxes.

6. RELATED PARTY TRANSACTIONS

   (a)  Transactions with Morgan Stanley Entities

        In connection with the Acquisition, Media entered into the Credit
Agreement with Morgan Stanley Senior Funding and Morgan Stanley & Co.

these services the Morgan Stanley Entities received customary fees and expense
reimbursement.

   (b)  Transactions with Time Warner and Related Parties

        In connection with the Acquisition, Media entered into an agreement with
Time Warner, pursuant to which Time Warner manages the Company's programming in
exchange for providing the Company access to certain Time Warner programming

INTRODUCTION AND RECENT DEVELOPMENTS

     Renaissance Media Group LLC ("Group") was formed by Renaissance Media
Holdings LLC on March 13, 1998.  Group was formed to acquire, operate and
develop cable television systems through its subsidiaries in markets within the
United States.  Group and its wholly-owned subsidiaries are collectively
referred to as (the "Company").  Prior to March 13, 1998 the Company's start-up
activities were conducted by Renaissance Media Holdings LLC and Renaissance
Media LLC.

     On April 9, 1998, the Company completed its first acquisition.  Pursuant to
the Asset Purchase Agreement dated November 14, 1997 with TWI Cable, the Company
acquired cable television systems which are clustered in southern Louisiana,
western Mississippi and western Tennessee and, as of September 30, 1998, passed
181,137 homes, served 127,919 basic subscribers and had 59,831 premium service
units.  The Company is the 4th largest cable television system operator in
Louisiana and the 5th largest cable television system operator in Tennessee
based upon the Systems' numbers of subscribers at September 30, 1998.

     The Company intends to increase its subscriber base and operating cash flow
by pursuing cable television system acquisitions, improving and upgrading its
technical plant and expanding its service offerings.  The Company will pursue
selective acquisitions in markets which are contiguous to the Systems and in
non-contiguous mid-sized markets serving more than 30,000 subscribers where
local or regional clusters can be formed.  The Company believes that by
clustering systems it will be able to realize economies of scale, such as
reduced payroll, reduced billing and technical costs per subscriber, reduced
advertising sales costs, increased local advertising sales, more efficient roll-
out and utilization of new technologies and consolidation of  its customer
service functions.  The Company plans to improve and upgrade its technical
plant, which should allow it to provide a wide array of new services and service
tiers, as well as integrate new interactive features into advanced analog and
digital set-top consumer equipment.  The Company also plans to develop and
provide new cable and broadband services and develop ancillary businesses
including digital video and high speed Internet access services.

     Revenues.  The Systems' revenues are primarily attributable to subscription
fees charged to subscribers for basic and premium cable television programming
services.  Basic revenue consists of monthly subscription fees for basic and
CPST satellite services.  Multiple dwelling unit accounts typically are offered
a bulk rate in exchange for single point billing and basic service to all units.
Premium revenue consists of monthly subscription fees for programming provided
on a per-channel basis.  In addition, other revenue is derived from new product
tiers, pay-per-view fees, installation and reconnection fees charged to
subscribers to receive service, monthly equipment rental fees, advertising
revenue and commissions related to the sale of goods by home shopping services
and in home wiring service contracts.


                                       11

     Service Costs.  Service costs are comprised of variable expenses directly
attributable to the Systems.  Variable operating expenses consist of costs
directly attributable to providing cable services to customers and therefore
generally vary directly with revenues.  Variable operating expenses include
salaries and related costs of service and technical personnel, programming fees
paid to suppliers of programming included in the Systems' basic and premium
cable television services, as well as expenses related to maintenance of cable
plants, vehicles costs, pole rents and electricity.

THREE MONTHS ENDED SEPTEMBER 30, 1998

     Revenues.  The Company had revenue of $14.2 million for the three months

     Provision for Taxes.  Renaissance Louisiana and Renaissance Tennessee have
elected to be treated as corporations for United States federal income tax
purposes.  The provision for taxes for the three months ended September 30, 1998
represents Tennessee Corporate Franchise tax expense.  No income tax benefit for
the loss incurred for the three months ended September 30, 1998 has been
recorded due to the uncertainty of the realization of such loss during the
related carry forward period.

ended September 30, 1998 was $4.4 million.

NINE MONTHS ENDED SEPTEMBER 30, 1998

incurred prior to the consummation of the Acquisition of the Systems on April 9,
1998.

      Depreciation and Amortization.  Depreciation and amortization consists of
depreciation and amortization primarily for the period from April 9, 1998 to
September 30, 1998 as the Company had no material assets subject to depreciation
or amortization prior to April 9, 1998.

      Interest Expense.  Interest expense was $9.1 million for the nine months
ended September 30, 1998.  This amount represents interest on the Notes and the
Credit Agreement for the period April 9, 1998 to September 30, 1998.

      Provision for Taxes.  Renaissance Louisiana and Renaissance Tennessee have

purposes.  The provision for taxes for the nine months ended September 30, 1998

uncertainty of the realization of such loss during the related carry forward
period.

      Net Loss.  Net loss for the nine months ended September 30, 1998 was $8.0
million, of which approximately $7.9 million was incurred during the period from

NINE MONTHS ENDED SEPTEMBER 30, 1998 (PRO FORMA) COMPARED WITH NINE MONTHS ENDED
SEPTEMBER 30, 1997 (PRO FORMA)

     The following discussion gives pro forma effect to the offering of the
Notes, Credit Agreement and the Acquisition (collectively the "Transactions") as
if they had occurred as of January 1, 1998 and 1997, and is provided for
informational purposes.  It does not purport to be indicative of the results
which would have actually been obtained had the Transactions been completed on
the dates indicated or which may be expected to occur in the future. As the
Company had no operations prior to the acquisition of the TWI Cable Systems
discussed above and in Note 4 to the Company's Consolidated Financial
Statements, the following discussion compares the nine months ended September
30, 1998 Pro Forma results of operations to the nine months ended September 30,
1997 Pro Forma Financial results of operations.  The discussion relating to the
pro forma comparisons has been condensed due to different grouping of expenses
between TWI Cable and the Company.

     The Systems served 127,919 basic subscribers at September 30, 1998 compared
with 125,405 basic subscribers at September 30, 1997, an increase of 2,514
subscribers or 2.0%.  Homes passed increased to 181,137 at September 30, 1998
from 177,402 at September 30, 1997, an increase of 3,735 homes passed or 2.1%.
Premium service units decreased to 59,831 at September 30, 1998 from 66,718 at
September 30, 1997.

     Revenues.  Revenues increased $4.4 million, or 11.7%, to $42.4 million for
the nine months ended September 30, 1998 from $38.0 million for the nine months
ended September 30, 1997.  There were no pro forma adjustments to revenues.

     The increase in revenues for the nine months ended September 30, 1998
resulted primarily from increases in basic revenue and other revenue.  Basic
revenue increased due to an increase in the weighted average monthly
subscription rate for basic service to $7.88 in 1998 from $7.69 in 1997 and an
increase in the weighted average monthly subscription rate for cable programming
service tiers ("CPST" ) to $20.28 in 1998 from $17.33 in 1997.  In addition,
basic revenue increased due to the increase in subscribers in the nine months
ended September 30, 1998.  Other revenue components including home shopping,
pay-per-view and advertising revenue increased, while additional outlet revenue
decreased.

                                       13
<PAGE>
 
     Expenses.  Expenses increased $1.7 million, or 4.2%, to $42.0 million for
the nine months ended September 30, 1998 from $40.3 million for the nine months
ended September 30, 1997.  The increase in system operating expenses for the
nine months ended September 30, 1998 resulted primarily from increases in
programming costs due to annual price increases and the addition of new
programming services and increases in other overhead costs such as insurance,
electricity, pole rents and property taxes, offset in part by increases in
capitalized internal labor and overhead costs attributable to increased capital
projects.

     Operating Income.  Operating income increased $2.7 million to $.4 million
for the nine months ended September 30, 1998 from an operating loss of $2.3
million for the nine months ended September 30, 1997.  The increase in operating
income resulted from the increase in revenue of $4.4 million offset in part by
the increase in operating expenses of $1.7 million for the nine month period
ended September 30, 1998.

     Net Loss.  For the reasons discussed above, net loss decreased $2.7
million, or 16.5%, to $13.9 million for the nine months ended September 30, 1998
from $16.6 million for the nine months ended September 30, 1997.

LIQUIDITY AND CAPITAL RESOURCES

     The cable television business requires substantial capital for the
upgrading, expansion and maintenance of signal distribution equipment, as well
for home subscriber devices and wiring and for service vehicles.  The Company
will continue to deploy fiber optic technology and to upgrade the Systems to a
minimum of 550 MHz and to 860 MHz where system characteristics warrant.  The
deployment of fiber optic technology will allow the Company to complete future
upgrades to the Systems in a cost-effective manner.  In addition, the Company
believes that the application of digital compression technology will likely
reduce the requirement in the future for upgrades to increase capacity beyond
860 MHz.

     The working capital requirements of a cable television business are
generally not significant since subscribers are billed for services monthly in
advance, while the majority of expenses incurred (except for payroll) are paid
generally 30-60 days after their incurrence.

     The Systems' net cash provided by operations was $16.1 million for the nine
months ended September 30, 1998.  The Systems' net cash used in investing
activities was $313.8 million for the nine months ended September 30, 1998
consisting primarily of the acquisition of the Systems. Net cash provided by
financing activities was $302.8 for the nine months ended September 30, 1998
consisting primarily of the proceeds received by the Company from: (i) the
Credit Agreement, (ii) the Notes and (iii) capital contributions.

     EBITDA represents operating (loss) before depreciation and amortization.
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.  EBITDA is included herein because the Company believes that EBITDA
is a meaningful measure of performance as it is commonly used in the cable
television industry 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 EBITDA.  The
Company's definition of EBITDA may not be identical to similarly titled measures
by other companies.  The System's EBITDA was $13.3 and $7.0 million for the nine
months and three months ended September 30, 1998, respectively, (49.0% and 49.5%
of revenue, respectively).

     Simultaneously with the offering of the Notes:  (i) the Company received
equity contributions of $95.1 million from the Morgan Stanley Entities and $3.9
million from the Management Investors;  (ii) Renaissance Media, as borrower, and
Renaissance Louisiana, Renaissance Tennessee and Renaissance Capital, as
guarantors, entered into the Credit Agreement, consisting of $110.0 million in
Term Loans and the $40.0 million Revolver; and (iii) Renaissance Media acquired
the Systems from TWI Cable for $300.0 million in cash and the issuance to TWI
Cable of a $9.5 million equity interest in Holdings.

     The Company used the net proceeds from the Notes offering, together with
the equity contributions and borrowings under the Term Loans, to consummate the
Acquisition.  The Company has approximately $207.3 million of indebtedness
outstanding and unused commitments under the Revolver of $40.0 million.  Subject
to compliance with the terms of the Credit Agreement, borrowings under the
Revolver will be available for working capital purposes, capital expenditures
and acquisitions.  In July 1998 the Company received additional equity
contributions of $.1 million from Holdings.

     The Company expects to make substantial investments in capital to: (i)
upgrade its cable plant; (ii) build line extensions; (iii) purchase new
equipment; and (iv) acquire the equipment necessary to implement its digital and
Internet and data transmission strategy.  In 1998, the Company estimates it will
make capital expenditures of approximately $5.0 million, down from its original
estimate of $9.8 million, due to design delays relating to plant upgrades.  The
difference in estimates will be carried over into 1999.  The Company believes
that the borrowings expected to be available under the Revolver and anticipated
cash flow from operations will be sufficient to upgrade the Systems as currently
contemplated and to satisfy the Company's working capital, capital expenditure
and debt service requirements.  However, the actual amount and timing of the
Company's capital requirements may differ materially from the Company's
estimates as a result of, among other things, the demand for the Company's
services and regulatory, technological and competitive developments (including
additional market developments and new opportunities) in the Company's industry.
The Company also expects that it will require additional financing if the
Company's development plans or projections change or prove to be inaccurate or
the Company engages in any acquisitions.  Sources of additional financing may
include commercial bank borrowings, vendor financing or the private or public
sale of equity or debt securities.  There can be no assurances that such
financing will be available on terms acceptable to the Company or at all.

     Borrowings under the Credit Agreement bear interest at floating rates,
although the Company is required to maintain interest rate protection programs.
Renaissance Media's obligations under the Credit Agreement are secured by
substantially all the assets of Renaissance Media.

     The Company is subject to interest rate fluctuations on its Credit
Agreement ($102.5 million outstanding at September 30, 1998) and, accordingly,
has entered into an interest rate cap agreement with a notional amount of $100.0
million.  This agreement serves to cap the interest rates associated with the
Company's variable rate debt under the Credit Agreement.  The cap agreement
protects the Company from increased interest costs if LIBOR exceeds 7.25% and
expires on December 1, 1999.

     The Company assesses its interest rate protection options on an ongoing
basis with a goal of having in place interest rate protection plans as it deems
appropriate, based on its assessment of future interest rates balanced against
the cost of such plans and the degree of interest rate fluctuation risk the
Company believes is appropriate.

YEAR 2000 ISSUES

     The Company relies on computer systems, related software applications and
other control devices in operating and monitoring all major aspects of its
business, including, but not limited to, its financial systems (such as general
ledger, accounts payable and payroll modules), subscriber billing systems,
internal networks and telecommunications equipment.  The Company also relies,
directly and indirectly, on the external systems of various independent business
enterprises, such as its suppliers and financial organizations, for the accurate
exchange of date and related information.

     The Company continues to assess the likely impact of Year 2000 issues on
its business operations, including its material information technology ("IT")
and non-IT applications.  These material applications include all billing and
subscriber information systems, general ledgers, phone switches and certain
headend applications, all of which are third party supported.  The Company has
received written assurances from the providers of all third party-supported
applications to the effect that such applications are either Year 2000 compliant
or subject to plans to become Year 2000 compliant.  The Company is currently
quantifying its non-IT applications, which may be affected by Year 2000 issues
and have an effect on its operations.



                                       15
<PAGE>
 
     The Company continues to monitor Year 2000 issues and expects to have all
systems identified by the end of 1998 and compliance determinations completed by
the end of the first calendar quarter of 1999.  Based on the results of its
compliance determinations, appropriate contingency plans will be finalized to
the extent possible.

     The Company has not incurred any material Year 2000 costs to date, and
excluding the need for contingency plans, does not expect to incur any material
Year 2000 costs in the future because most of the applications it uses are
maintained by third parties who have borne such Year 2000 compliance costs.

     The Company cannot be certain that it or third parties supporting its
systems have resolved or will resolve all Year 2000 issues in a timely manner.
Failure by the Company or any such third party to successfully address the
relevant Year 2000 issues could result in disruptions of the Company's business
and the incurrence of significant expenses by the Company.  Additionally, the
Company could be affected by any disruption to third parties with which the
Company does business if such third parties have not successfully addressed
their Year 2000 issues.

IMPACT OF INFLATION

     With the exception of programming costs, the Company does not believe that
inflation has had or will likely have a significant effect on its results of
operations or capital expenditure programs.  Programming cost increases in the
past have tended to exceed inflation and may continue to do so in the future.
The Company, in accordance with FCC regulations, may pass along programming cost
increases to its subscribers.
