             CHARTER COMMUNICATIONS SOUTHEAST, L.P. AND SUBSIDIARIES


                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


1.   ORGANIZATION AND BASIS OF PRESENTATION:

The accompanying consolidated financial statements of Charter Communications
Southeast, L.P. (Charter Southeast) and subsidiaries include the accounts of
Charter Southeast and its direct and indirect wholly owned subsidiaries: Charter
Communications Southeast Capital Corporation, CCP II, Inc., CCP One, Inc.,
Charter Communications II, L.P. (CC-II), and Charter Communications, L.P.
(CC-I), collectively referred to as the "Partnership" or the "Company" herein.
All significant intercompany balances and transactions have been eliminated in
consolidation.

The accompanying unaudited financial statements 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.

Certain reclassifications have been made to the June 30, 1997 financial
statements to conform with the June 30, 1998 presentation.


2.   RESPONSIBILITY FOR INTERIM FINANCIAL STATEMENTS:

The consolidated financial statements as of June 30, 1998 and 1997, are
unaudited; however, in the opinion of management, such statements include all
adjustments necessary for a fair presentation of the results for the periods
presented. The interim consolidated financial statements should be read in
conjunction with the consolidated financial statements and notes thereto
contained in the Registrant's Form 10-K for the year ended December 31, 1997.
Interim results are not necessarily indicative of results for a full year.


3.   LITIGATION

A purported class action lawsuit on behalf of the Cencom Cable Income Partners,
L.P. (CCIP) limited partners was filed in 1995 (the "Action"), which sought,
among other things, to enjoin permanently the purchase of systems from CCIP,
including those by CC-II (the "CCIP Acquisition"). On February 15, 1996, all of
the plaintiff's claims for injunctive relief were dismissed (including that
which sought to prevent the consummation of the CCIP Acquisition); the
plaintiff's claims for money damages which may have resulted from the CCIP
Acquisition remain pending. In October 1996 the plaintiff filed a Consolidated
Amended Class Action Complaint (the "Amended Complaint"). The general partner of
CCIP believed that portions of the Amended Complaint were legally inadequate and
filed a dispositive motion as to all remaining claims in the Action. In October
1997, The court granted in part and denied in part the defendants motion, the
effect of which narrowed the remaining issues significantly. Each of the
defendants in the Action including the Partnership, believes the Action, which
remains pending, to be without merit and is contesting it vigorously. There can
be no assurance, however, that the plaintiff will not be awarded damages, some
or all of which may be payable by the Partnership, in connection with the
Action.

In June 1997, a purported class action lawsuit was filed in Delaware Chancery
Court under the name of Wallace, Mathews, Lerner and Roberts v. Wood et.al.,
Case No. 15731, by certain limited partners of Cencom Cable Income Partners II,
L.P. (CCIP II), a publicly held limited partnership, against numerous
defendants. The suit alleges that defendants CC-I and CC-II, both of which are
related to CCIP II's general partner, purchased cable television systems from
CCIP II in April 1997 at less than fair value. In connection with the purchase
of these assets, CC-I and CC-II paid the highest amount bid in a multiple round
auction process involving nonaffiliated third parties. 



                                     Page 8
<PAGE>   9

Furthermore, the assets acquired had been appraised by two independent
appraisers, the purchase price paid as a result of the auction was higher than
the appraised value, and the proposed sale to the purchasers was approved by a
majority of CCIP II's limited partners. In November 1997, the plaintiffs amended
their complaint to restate their allegations as a shareholders' derivative
claim. For these reasons, amongst others, management of the Partnership believes
that the claims against CC-I and CC-II are without merit and will defend them
vigorously.

The Partnership is also a party to lawsuits which are generally incidental to
its business. In the opinion of management, after consulting with legal counsel,
the outcome of these lawsuits will not have a material adverse effect on the
Partnership's consolidated financial position or results of operations.


4.   LONG-TERM DEBT

On June 1, 1998, the Partnership repaid and terminated the separate credit
facilities of CC-I and CC-II from borrowings of its new revolving credit and
term loan facilities. The new $640 million credit facilities were arranged
through a consortium of banks and consist of a $290 million revolver maturing
June 2007 and a pair of term facilities in the amounts of $200 million and $150
million maturing June 2007 and December 2007, respectively. The new credit
facilities are structured as a joint credit agreement whereby CC-I and CC-II
(and its subsidiaries) are each jointly and severally liable for the debt. The
credit facilities bear interest, at borrower's option, at rates based upon the
prime rate of the agent bank or based upon Eurodollar rates plus the applicable
margin determined by the Partnership's leverage ratio at the time of the
borrowing. The variable interest rates ranged from 7.03% to 7.69% at June 30,
1998. The extraordinary loss recognized by the Partnership due to the early
retirement of debt was related to the write off of deferred debt issuance costs
for the terminated credit facilities of CC-I and CC-II.


5.   SUBSEQUENT EVENT

On July 29, 1998, Charter Communications, Inc. ("CCI"), the company that
provides management service to the Partnership and its subsidiaries, along with
certain of its affiliates and their respective shareholders, entered into a
Purchase Agreement (the "Purchase Agreement") with Paul G. Allen pursuant to
which Mr. Allen agreed to purchase all of the outstanding privately-held equity
interests of CCI and the various other entities that together constitute the
owners and/or managers of the cable television systems operated under the name
"Charter Communications". The obligation of Mr. Allen to purchase these equity
interests is subject to the satisfaction of certain conditions set forth in the
Purchase Agreement including, without limitation, obtaining all necessary
governmental approvals. It is currently expected that the acquisition by Mr.
Allen will occur in December 1998. If the acquisition is consummated, the
Partnership will be obligated under the terms of the Indenture governing its
11.25% Senior Notes due 2006 (the "Senior Notes") to make an offer to repurchase
all outstanding Notes at a purchase price equal to 101% of the principle amount
thereof plus all accrued and unpaid interest to the date of purchase.

third party for approximately $5.9 million. There are no other pending
acquisitions.

Service Revenues

The Partnership earns substantially all of its revenues from monthly
subscription fees for basic tier, expanded tier, premium channels, equipment
rental and ancillary services provided by its cable television systems. Service
revenues increased by 10.8% and 19.6% to $ 50.3 million and $ 98.4 million for
the three and six month periods ended June 30, 1998, respectively, when compared
to the similar period of 1997. These increases in 1998 are primarily due to an
increase in subscribers for the basic tier of cable service offered by the
systems resulting primarily from acquisitions of cable systems by the
Partnership throughout 1997. In addition, the Partnership experienced
significant internal subscriber growth (See supplemental analysis of quarterly
operating results) between periods and implemented basic and expanded tier
retail rate increases in certain systems, in accordance with federal law. The
internal subscriber growth reflects the success of management's marketing
efforts to add new customers and retain existing customers, as well as improved
customer service. In addition, a limited amount of new-build construction
increased the coverage of the systems.

Operating Expenses

Operating costs increased by 7.1% and 16.7% to $ 21.1 million and $ 41.2 million
for the three and six months ended June 30, 1998, respectively, when compared to
the similar periods of 1997. The majority of these increases were related to
costs associated with the acquisitions of additional cable television systems
during 1997. Operating costs, as a percentage of service revenues, have
decreased from 43.3% for the quarter ended June 30, 1997 to 41.8% for the
quarter ended June 30, 1998, primarily as a result of the Partnership's efforts
to increase operating efficiencies as a result of clustering its cable
television systems.

General and administrative expenses increased by 14.6% and 22.3% for the three
and six months ended June 30, 1998 when compared to the similar periods of 1997.
These increases are primarily a result of the costs associated with acquisitions
of additional cable television systems during 1997. General and administrative
expenses, as a percentage of service revenues, have increased to 7.8% from 7.5%
for the quarters ended June 30, 1998 and June 30, 1997, respectively, as a
result of increased salary and wage costs.

Depreciation and amortization increased by 17.9% and 28.8% and $ 21.9 million
and $43.1 million for the three and six months ended June 30, 1998,
respectively, when compared to the similar periods of 1997. These increases in
depreciation and amortization are a result of capital expenditures made to the
Systems, in addition to the increase in property, plant and equipment and
franchise costs resulting from the acquisitions of additional cable systems
during 1997. Depreciation expense as a percent of revenues increased during the
three and six months ended June 30, 1998 compared to the similar periods of
1997. These increases are due primarily to a decrease in the estimated useful
lives used in calculating depreciation.


Other Income/Expense

Interest expense increased by 7.1% and 17.3% to $13.3 million and $26.5 million
for the three and six months ended June 30, 1998, respectively, when compared to
the similar periods of 1997. These increases were primarily due to the increase
in the average outstanding bank debt balance between the comparable periods. The
extraordinary loss due to the early retirement of the separate CC-I and CC-II
credit facilities relates to the write-off of deferred debt issuance costs of
each facility.

Net Loss

Net loss increased by 71.0 % and 60.1% to $18.5 million and $31.3 million for
the three and six months ended June 30, 1998 when compared to the similar
periods of 1997. In 1998, increased depreciation and the extraordinary item were
significant factors versus the prior year.

Liquidity and Capital Resources

The Partnership's growth by acquisition during 1998 and 1997 has been funded
primarily by borrowings under bank credit facilities, the 11 1/4% Senior Notes
(the "Senior Notes"), and equity contributions. Cash flows provided by operating
activities together with borrowings under bank credit facilities have been
sufficient to fund the Partnership's debt service, capital expenditures and
working capital requirements. Future cash flows provided by operating activities
and availability for borrowings under the existing credit facilities are
anticipated to be sufficient during the next 12 months for the Partnership's
ongoing debt service, capital expenditures and working capital needs. The
Partnership anticipates that future acquisitions could be financed through
borrowings, either presently available under the existing credit facilities, or
as a result of amending the existing credit facilities to allow for expanded
borrowing capacity, combined with additional equity contributions. Although to
date the Partnership has been able to obtain financing on satisfactory terms,
there can be no assurance that this will continue to be the case in the future
and, thereby, could negatively impact the Partnership's ability to pursue a
strategy that includes growth through acquisitions.

On June 1, 1998, the Partnership repaid and terminated the separate credit
facilities of CC-I and CC-II from borrowings of its new revolving credit and
term loan facilities. The new $640 million credit facilities were arranged
through a consortium of banks and consist of a $290 million revolver maturing
June 2007 and a pair of term facilities in the amounts of $200 million and $150
million maturing June 2007 and December 2007, respectively. The new credit
facilities are structured as a joint credit agreement whereby CC-I and CC-II
(and its subsidiaries) are each jointly and severally liable for the debt. The
credit facilities bear interest, at borrower's option, at rates based upon the
prime rate of the agent bank or based upon Eurodollar rates plus the applicable
margin determined by the Partnership's leverage ratio at the time of the
borrowing. The variable interest rates ranged from 7.03% to 7.69% at June 30,
1998. The extraordinary loss recognized by the Partnership for the early
extinguishment of debt was related to the write off of deferred debt issuance
costs for the terminated credit facilities of CC-I and CC-II.

At June 30, 1998, the Partnership's long-term debt of $ 602.4 million consisted
of $477.4 million outstanding under the revolving credit and term loan facility,
and $125.0 million of indebtedness from the sale of the Senior Notes. The
Partnership had unused and available borrowing capacity of $162.6 million at
June 30, 1998.

On July 29, 1998, Charter Communications, Inc. ("CCI"), the company that
provides management service to the Partnership and its subsidiaries, along with
certain of its affiliates and their respective shareholders, entered into a
Purchase Agreement (the "Purchase Agreement") with Paul G. Allen pursuant to
which Mr. Allen agreed to purchase all of the outstanding privately-held equity
interests of CCI and the various other entities that together constitute the
owners and/or managers of the cable television systems operated under the name
"Charter Communications". The obligation of Mr. Allen to purchase these equity
interests is subject to the satisfaction of certain conditions set forth in the
Purchase Agreement including, without limitation, obtaining all necessary
governmental approvals. It is currently expected that the acquisition by Mr.
Allen will occur in December 1998. If the acquisition is consummated, the
Partnership will be obligated under the terms of the Indenture governing its
11.25% Senior Notes due 2006 to make an offer to repurchase all outstanding
Notes at a purchase price equal to 101% of the principle amount thereof plus all
accrued and unpaid interest to the date of purchase.

Cash interest is payable on a monthly and quarterly basis for borrowings
outstanding under the credit facilities. Cash interest is payable semi-annually,
in March and September, on the Senior Notes until March 2006. The discount
related to the original sale of the Debentures is amortized through March 2001;
thereafter, cash interest is payable on a semi-annual basis in March and
September until March 2007.

The Partnership manages risk arising from fluctuations in interest rates through
the use of interest rate swap and cap agreements required under the terms of the
existing credit facilities. Interest rate swap and cap agreements are accounted
for by the Partnership as a hedge of the debt obligation. As a result, the net
settlement amount of any such swap or cap is recorded as interest expense in the
period incurred. The affects of the Partnership's hedging practices on its
weighted average borrowing rate and on reported interest expense were not
material for the three and six months ended June 30, 1998.

The Partnership incurred capital expenditures of approximately $41.6 million
during the first quarter of 1998 in connection with the improvement and
upgrading of the Partnership's cable systems. The Partnership anticipates that
capital expenditures for such purposes will be approximately $80.0 to $90.0
million during fiscal 1998.

During 1997 and 1998, the Partnership held discussions with several
municipalities, counties and utility companies in Georgia to explore the
possibility of a sale-leaseback venture whereby the Partnership would sell its
cable television distribution plant and subsequently enter into a long-term
capital lease to continue to operate the cable television system. On August 4,
1998, the Partnership and the City of LaGrange, Georgia, entered into such an
arrangement involving approximately 8,200 customers. The proceeds of a municipal
bond offering will be utilized for the initial purchase of the cable television
system for approximately $2.2 million with the remaining funds to finance the
upgrade of the cable television system to 750 MHz. Upon completion of the
upgrade in 1999, the Partnership will reflect a 16 year capital lease agreement
with an obligation of approximately $7.0 million recorded by the Partnership.

The Partnership has insurance covering risks incurred in the ordinary course of
business, including general liability, property and business interruption
coverage. As is typical in the cable television industry, the Partnership does
not maintain insurance covering its underground plant, the cost of which
management believes is currently prohibitive. Management believes that the
Partnership's insurance coverage is adequate, and intends to monitor the
insurance markets to attempt to obtain coverage for the Partnership's
underground plants at reasonable and cost-effective rates.

The Partnership believes that it has generally complied with the provisions of
the 1992 Act regarding cable programming service rates. However, some systems
may be charging rates which are in excess of allowable rates and, accordingly,
may be subject to challenge by regulatory authorities, such challenge may result
in the Partnership being required to make refunds to subscribers. The amount of
refunds, if any, which could be payable by the Partnership in the event such
systems' rates are successfully challenged by regulatory authorities is not
currently estimable. The Partnership has not reserved any amounts for payment of
such refunds as the General Partner does not believe that the amounts of any
such refunds would have a material adverse effect on the financial position or
results of the Partnership.

Year 2000 Impact

As of the quarter ended June 30, 1998, the Company is engaged in a process to
identify and address issues surrounding the Year 2000 and its impact on the
Company's operations. The issue surrounding the Year 2000 is whether the
computer systems, software and all equipment using a computer chip will properly
recognize date sensitive information when the year changes to 2000, or "00".
Computerized systems that do not properly recognize such information could
generate erroneous data or cause a system to fail. This issue impacts the
Company as to its owned or licensed computer systems and equipment used in
connection with internal operations, including systems, software and equipment
supplied by vendors and third party service providers. The Company may also be
affected by virtue of its external dealings with third parties in the regular
course of business. As management of the Company has not completed its initial
assessment of the impact the Year 2000 may have on the Company's operations, it
cannot estimate the costs associated with ensuring the Company's operations are
Year 2000 compliant. The Company is in the initial phases of determining the
impact of the Year 2000, and management anticipates completion of the project by
December 1998, allowing adequate time for testing. However, there can be no
assurance that the Company's operations or the computer systems of other
companies with whom the Company conducts business will be Year 2000 compliant
prior to December 31, 1999. If such modifications and conversions are not
completed timely, the Year 2000 problem may have a material impact on the
operation of the Company.

</TABLE>

     (a) EBITDA represents income before interest expense, income taxes,
     depreciation and amortization, management fees and other income (expense).
     EBITDA is calculated before payment of management fees so as to be
     consistent with certain financial terms contained in the revolving credit
     and term loan facilities. Management fees paid by the Company are
     calculated as 5% of service revenues, 60% of which is payable currently and
     40% is deferred. Management believes that EBITDA is a meaningful measure of
     performance because 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. EBITDA is not presented in accordance
     with generally accepted accounting principles and should not be considered
     an alternative to, or more meaningful than, operating income or operating
     cash flows as an indicator of the Partnership's operating performance.
     EBITDA does not include the Partnership's debt obligations or other
     significant commitments.

     (b) Homes passed as previously reported for June 30, 1997 were revised
     upward by 13,000 homes passed as a result of management's review and
     verification of the engineering and billing records.

Results of Operations - Supplemental Analysis for the Quarter Ended June 30,
     1998 Versus the Quarter Ended June 30, 1997 (for Systems Acquired On or
     Before April 1, 1997)

The following discussion is provided to show the results of operations on a
comparable basis for those systems owned by the Partnership during the three
months ended June 30, 1998 versus the three months ended June 30, 1997.
Specifically, the comparable analysis includes the results of operations for
acquisitions completed between April 1994 and February 1997. - see Significant
Transactions for a complete listing of all acquisitions by the Partnership.

Service revenues increased by $4.1 million or 10.2% when comparing the revenues
for the quarter ended June 30, 1998 to the results for the comparable systems
for the quarter ended June 30, 1997. This increase is due to a net gain of
approximately 16,700 or 4.5% for basic subscribers between quarters and, second,
to retail rate increases implemented in certain of the Partnership's systems.

Operating expenses increased approximately $1.6 million or 7.9% when comparing
the operating expenses for the quarter ended June 30, 1998 to the results for
the comparable systems for the quarter ended June 30, 1997. This increase is
primarily due to increases in license fees paid for programming as a result of
additional subscribers, new channels launched and increases in the rates paid on
a per subscriber basis to the programming services. The Company believes that
the growth in programming expense is consistent with industry-wide increases.

The Partnership experienced growth in operating cash flow (EBITDA) of
approximately $2.5 million or 12.5% when comparing the operating cash flow for
the quarter ended June 30, 1998 to the results for the comparable systems for
the quarter ended June 30, 1997. EBITDA margin increased from 49.0% to 50.0%
when comparing the similar periods, primarily as a result of increased revenues
due to subscriber growth and retail rate increases.

Part II. Other Information

Item 1.  Legal Proceedings

A purported class action lawsuit on behalf of the Cencom Cable Income Partners,
L.P. (CCIP) limited partners was filed in 1995 (the "Action"), which sought,
among other things, to enjoin permanently the purchase of systems from CCIP,
including those by CC-II (the "CCIP Acquisition"). On February 15, 1996, all of
the plaintiff's claims for injunctive relief were dismissed (including that
which sought to prevent the consummation of the CCIP Acquisition); the
plaintiff's claims for money damages which may have resulted from the CCIP
Acquisition remain pending. In October 196, the plaintiff filed a Consolidated
Amended Class Action Complaint(the "Amended Complaint"). The general partner of
CCIP believed that portions of the Amended Complaint were legally inadequate and
filed a dispositive motion as to all remaining claims in the Action. In October
1997, The court granted in part and denied in part the defendants motion, the
effect of which narrowed the remaining issues significantly. Each of the
defendants in the Action including the Partnership, believes the Action, which
remains pending, to be without merit and is contesting it vigorously. There can
be no assurance, however, that the plaintiff will not be awarded damages, some
or all of which may be payable by the Partnership, in connection with the
Action.

In June 1997, a purported class action lawsuit was filed in Delaware Chancery
Court under the name of Wallace, Mathews, Lerner and Roberts v. Wood et.al.,
Case No. 15731, by certain limited partners of Cencom Cable Income Partners II,
L.P. (CCIP II), a publicly held limited partnership, against numerous
defendants. The suit alleges that defendants CC-I and CC-II, both of which are
related to CCIP II's general partner, purchased cable television systems from
CCIP II in April 1997 at less than fair value. In connection with the purchase
of these assets, CC-I and CC-II paid the highest amount bid in a multiple round
auction process involving nonaffiliated third parties. Furthermore, the assets
acquired had been appraised by two independent appraisers, the purchase price
paid as a result of the auction was higher than the appraised value, and the
proposed sale to the purchasers was approved by a majority of CCIP II's limited
partners. In November 1997, the plaintiffs amended their complaint to restate
their allegations as a shareholders' derivative claim. For these reasons,
amongst others, management of the Partnership believes that the claims against
CC-I and CC-II are without merit and will defend them vigorously.

The Partnership is also a party to lawsuits which are generally incidental to
its business. In the opinion of management, after consulting with legal counsel,
the outcome of these lawsuits will not have a material adverse effect on the
Partnership's consolidated financial position or results of operations.
