                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1. INTERIM FINANCIAL STATEMENTS

     The accompanying condensed interim financial statements for Enstar
Income/Growth Program Six-A, L.P. (the Partnership), as of March 31, 2002, and
for the three months ended March 31, 2002 and 2001, are unaudited. These
condensed interim financial statements should be read in conjunction with the
audited financial statements and notes thereto included in our Annual Report on
Form 10-K for the year ended December 31, 2001. In the opinion of management,
the condensed interim financial statements reflect all adjustments (consisting
only of normal recurring adjustments) necessary for a fair presentation of the
results of such periods. The results of operations for the three months ended
March 31, 2002 are not necessarily indicative of results for the entire year.

2. TRANSACTIONS WITH THE GENERAL PARTNERS AND AFFILIATES

     The Partnership has a management and service agreement (the Management
Agreement) with Enstar Cable Corporation (Enstar Cable), a wholly owned
subsidiary of Enstar Communications Corporation (ECC), the Corporate General
Partner, for a monthly management fee of 5% of gross revenues, as defined, from
operations of the Partnership, excluding revenues from the sale of cable
television systems or franchises, payable to Enstar Cable. Management fee
expense was $38,700 and $40,800 for the three months ended March 31, 2002 and
2001, respectively. Management fees are non-interest bearing.

     In addition to the monthly management fee, the Partnership reimburses
Enstar Cable for direct expenses incurred on behalf of the Partnership, and for
the Partnership's allocable share of operational costs associated with services
provided by Enstar Cable. Additionally, Charter Communications Holding Company,
LLC and its affiliates (collectively, Charter) provide other management and
operational services for the Partnership. These expenses are charged to the
properties served based primarily on the Partnership's allocable share of
operational costs associated with the services provided. The total amount
charged to the Partnership for these services approximated $86,100 and $83,900
for the three months ended March 31, 2002 and 2001, respectively.

     All programming services have been purchased through Charter. Charter
charges the Partnership for these costs based on its costs. The Partnership
recorded programming fee expense of $182,500 and $166,200 for the three months
ended March 31, 2002 and 2001, respectively. Programming fees are included in
service costs in the accompanying condensed statements of operations.

3. NET INCOME (LOSS) PER UNIT OF LIMITED PARTNERSHIP INTEREST

     Net income (loss) per unit of limited partnership interest is based on the
average number of units outstanding during the periods presented. For this
purpose, net income (loss) has been allocated 99% to the Limited Partners and 1%
to the General Partners. The General Partners do not own units of partnership
interest in the Partnership, but rather hold a participation interest in the
income, losses and distributions of the Partnership.

4. LONG-TERM DEBT

     The Partnership was party to a loan agreement with Enstar Finance Company,
LLC, a subsidiary of ECC. The loan agreement provided for a revolving loan
facility of $3,600,000 and matured on August 31, 2001. The loan facility was not
extended or replaced. The Partnership signed an intercompany loan agreement in
the amount of $250,000 with Falcon Cable Communications, LLC, an affiliate of
the Partnership, for general working capital purposes. The loan matures on April
1, 2003 and bears interest at LIBOR plus 2.50% (4.54% at March 31, 2002).

5.  SALE OF ASSETS

     On August 29, 2001, the Partnership entered into an asset purchase
agreement providing for the sale of all of the Partnership's Illinois cable
television systems in and around Cisne, Farmersville, Flora, Noble, Raymond,
Salem and Xena, Illinois (the Flora cable television systems) to Rifkin
Acquisition Partners, LLC (RAP), an affiliate of the Corporate General Partner
and an indirect subsidiary of Charter, for a total sale price of approximately
$12,674,500 (the Charter Sale). As a pre-condition to the sale, based on
approval by the Limited Partners, the

                                   (UNAUDITED)

Partnership's partnership agreement was amended to allow the sale of assets to
an affiliate of the Corporate General Partner. On April 10, 2002, the asset
purchase agreement closed. Beginning April 10, 2002, the Partnership will
present the Flora cable television systems as discontinued operations. During
the three months ended March 31, 2002, the Flora cable television systems earned
revenue of $565,800. At March 31, 2002, the Flora cable television systems had
approximately 5,300 and 900 basic and premium customers, respectively. The
Partnership expects to recognize a gain from the sale of the Flora cable
television systems, although no assurance can be given regarding this matter.

     The Dyer, Tennessee headend is not included in the Charter Sale and will
continue to be owned by the Partnership and operated by the Corporate General
Partner indefinitely for the foreseeable future. The Corporate General Partner
can give no assurance of when, or if, the Dyer, Tennessee headend will ever be
sold.

6.  RECENTLY ISSUED ACCOUNTING STANDARDS

     In April 2002, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 145, "Rescission of FASB
Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical
Corrections." SFAS No. 145 provides for the rescission of several previously
issued accounting standards, new accounting guidance for the accounting for
certain lease modifications and various technical corrections that are not
substantive in nature to existing pronouncements. SFAS No. 145 will be adopted
by the Partnership beginning January 1, 2003, except for the provisions relating
to the amendment of SFAS No. 13, which will be adopted for transactions
occurring subsequent to May 15, 2002. Adoption of SFAS No. 145 will not have a
material impact on the condensed financial statements of the Partnership.

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

INTRODUCTION

     This report includes certain forward-looking statements regarding, among
other things, our future results of operations, regulatory requirements,
competition, capital needs and general business conditions applicable to us.
Such forward-looking statements involve risks and uncertainties including,
without limitation, the uncertainty of legislative and regulatory changes and
the rapid developments in the competitive environment facing cable television
operators such as us. In addition to the information provided here, reference is
made to our Annual Report on Form 10-K for the year ended December 31, 2001, for
additional information regarding such matters and the effect thereof on our
business.

RESULTS OF OPERATIONS

     Revenues decreased $43,100 from $816,300 to $773,200, or 5.3%, for the
three months ended March 31, 2002 compared to the corresponding period in 2001.
The decrease was due to a decline in the number of basic and premium service
customers. As of March 31, 2002 and 2001, we had approximately 7,300 and 7,700
basic service customers, respectively, and 1,100 and 1,400 premium service
customers, respectively.

     Service costs increased $300 from $249,900 to $250,200, or less than 1%,
for the three months ended March 31, 2002 compared to the corresponding period
in 2001. Service costs represent programming costs and other costs directly
attributable to providing cable services to customers.

         General and administrative expenses decreased $10,900 from $125,000 to
$114,100, or 8.7%, for the three months ended March 31, 2002 compared to the
corresponding period in 2001 primarily due to a decrease in bad debt expense.

     General partner management fees and reimbursed expenses increased $100 from
$124,700 to $124,800, or less than 1%, for the three months ended March 31, 2002
compared to the corresponding period in 2001.

     Depreciation and amortization expense decreased $34,300 from $262,800 to
$228,500, or 13.1%, for the three months ended March 31, 2002 compared to the
corresponding period in 2001, due to a decrease in capital expenditures coupled
with certain fixed assets becoming fully depreciated during the last three
quarters of 2001 and the three months ended March 31, 2002.

         Due to the factors described above, our operating income increased
$1,700 from $53,900 to $55,600, or 3.2%, for the three months ended March 31,
2002 compared to the corresponding period in 2001.

     Interest income increased $400 from $500 to $900, or 80.0%, for the three
months ended March 31, 2002 compared to the corresponding period in 2001,
primarily due to an increase in average cash balances available for investment.

     Interest expense decreased $16,300 from $19,900 to $3,600, or 81.9%, for
the three months ended March 31, 2002 compared to the corresponding period in
2001, primarily due to the expiration of the loan facility on August 31, 2001.

     Other expense of $72,500 for the three months ended March 31, 2002
represents expenses associated with the sale of the Illinois cable television
systems.

     Due to the factors described above, our net income decreased $54,100 from
$34,500 to a net loss of $19,600, or 156.8%, for the three months ended March
31, 2002 compared to the corresponding period in 2001.

     Based on our experience in the cable television industry, we believe that
income before interest, income taxes, depreciation and amortization, or EBITDA,
and related measures of cash flow serve as important financial analysis tools
for measuring and comparing cable television companies in several areas, such as
liquidity, operating performance and leverage. EBITDA is not a measurement
determined under generally accepted accounting


                                       7
<PAGE>

principles (GAAP) and does not represent cash generated from operating
activities in accordance with GAAP. EBITDA should not be considered by the
reader as an alternative to net income, as an indicator of financial performance
or as an alternative to cash flows as a measure of liquidity. In addition, the
definition of EBITDA may not be identical to similarly titled measures used by
other companies. EBITDA decreased $105,100 from $316,700 to $211,600, or 33.2%,
for the three months ended March 31, 2002 compared to the corresponding period
in 2001. EBITDA as a percentage of revenues decreased 11.4% from 38.8% to 27.4%
for the three months ended March 31, 2002 compared to the corresponding period
in 2001.

     Operating activities provided $175,600 and $239,100 in the three months
ended March 31, 2002 and 2001, respectively. Changes in receivables, prepaid
expenses and other assets used $7,600 and provided $88,600 in the first three
months of 2002 and 2001, respectively, due to differences in the timing of
receivable collections and the payment of prepaid expenses. Changes in
liabilities owed to affiliates and third party creditors used $25,700 and
$146,800 during the three months ended March 31, 2002 and 2001, respectively,
due to differences in the timing of payments.

     Investing activities used $177,600 and $28,200 during the three months
ended March 31, 2002 and 2001, respectively, primarily due to capital
expenditures for our cable systems.

LIQUIDITY AND CAPITAL RESOURCES

     Our capital expenditures were $177,600 for the three months ended March 31,
2002. We do not anticipate making significant additional upgrades to cable plant
or headend electronics. See "Results of Operations" for discussion regarding
cash from operating, investing and financing activities.

INVESTING ACTIVITIES

     Significant capital would be required for a comprehensive plant and headend
upgrade, particularly in light of the high cost of electronics to activate
two-way service, for speed cable modem Internet and other interactive services,
as well as to increase channel capacity and allow a greater variety of video
services. Our capital expenditures for recent upgrades have been made with
available funds, and have enhanced the economic value of our systems.

     The estimated cost of all of these upgrades would be approximately $2.2
million (for an upgrade to 550 megahertz capacity) and $2.6 million (for an
upgrade to 870 megahertz capacity). Given the high cost of this comprehensive
upgrade plan, the limited funds available, and the belief that a comprehensive
plan is not economically prudent, Enstar Communications Corporation (the
Corporate General Partner) does not presently anticipate that it will proceed
with a comprehensive upgrade plan. Provided there are available funds, the
Corporate General Partner will, however, continue to evaluate alternative,
cost-effective solutions to increase channel capacity, pay-per-view services,
and digital services which would enhance the value of our systems and be
economically prudent.

FINANCING ACTIVITIES

     We were party to a loan agreement with Enstar Finance Company, LLC, a
subsidiary of the Corporate General Partner. The loan agreement provided for a
revolving loan facility of $3,600,000 and matured on August 31, 2001. The loan
facility was not extended or replaced. We signed an intercompany loan agreement
in the amount of $250,000 with Falcon Cable Communications, LLC, our affiliate,
for general working capital purposes. The loan matures on April 1, 2003 and
bears interest at LIBOR plus 2.50% (4.54% at March 31, 2002).

SALE OF ASSETS

     On August 29, 2001, we entered into an asset purchase agreement providing
for the sale of all of our Illinois cable television systems in and around
Cisne, Farmersville, Flora, Noble, Raymond, Salem and Xena, Illinois to Rifkin
Acquisition Partners, LLC (RAP), an affiliate of Enstar Communications
Corporation (the Corporate General Partner) and an indirect subsidiary of
Charter Communications Holdings Company, LLC, for a total sale price of
approximately $12,674,500 (the Charter Sale). As a pre-condition to the sale,
based on approval


                                       8
<PAGE>

by the Limited Partners, our partnership agreement was amended to allow the sale
of assets to an affiliate of the Corporate General Partner. On April 10, 2002,
the asset purchase agreement closed.

     The Dyer, Tennessee headend is not included in the Charter Sale and will
continue to be owned and operated by the Corporate General Partner indefinitely
for the foreseeable future. The Corporate General Partner can give no assurance
of when, or if, the Dyer, Tennessee headend will ever be sold.

     After setting aside a $1,000,000 reserve to fund the Dyer headend's working
capital needs, and paying or providing for the payment of the expenses of the
Charter Sale, the Corporate General Partner will make one or more distributions
of our allocable share of the remaining net sale proceeds, in accordance with
its partnership agreement. We intend to make an initial distribution of
approximately $109 per Limited Partnership unit on or about May 15, 2002, with a
second distribution of approximately $89 per Limited Partnership unit on or
about September 30, 2002.

COMMITMENTS AND CONTINGENCIES

     Insurance coverage is maintained for all of the cable television properties
owned or managed by Charter to cover damage to cable distribution systems,
customer connections and against business interruptions resulting from such
damage. This coverage is subject to a significant annual deductible which
applies to all of the cable television properties owned or managed by Charter,
including ours.

     Approximately 100% of our customers are served by our system in Dyer,
Illinois and neighboring communities. Significant damage to the system due to
seasonal weather conditions or other events could have a material adverse effect
on our liquidity and cash flow. We continue to maintain insurance coverage in
amounts our management views as appropriate for all other property, liability,
automobile, workers' compensation and other insurable risks.

     Although we do not believe that the terrorist attacks on September 11, 2001
and the related events have resulted in any material changes to our business and
operations to date, it is difficult to assess the impact that these events,
combined with the general economic slowdown, will have on future operations.
These events could result in reduced spending by customers and advertisers,
which could reduce our revenues and operating cash flow, as well as the
collectibility of accounts receivable.

RECENTLY ISSUED ACCOUNTING STANDARDS

     In April 2002, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 145, "Rescission of FASB
Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical
Corrections." SFAS No. 145 provides for the rescission of several previously
issued accounting standards, new accounting guidance for the accounting for
certain lease modifications and various technical corrections that are not
substantive in nature to existing pronouncements. SFAS No. 145 will be adopted
by us beginning January 1, 2003, except for the provisions relating to the
amendment of SFAS No. 13, which will be adopted for transactions occurring
subsequent to May 15, 2002. Adoption of SFAS No. 145 will not have a material
impact on the condensed financial statements.

INFLATION

     Certain of our expenses, such as those for wages and benefits, equipment
repair and replacement, and billing and marketing generally increase with
inflation. However, we do not believe that our financial results have been, or
will be, adversely affected by inflation in a material manner, provided that we
are able to increase our service prices periodically, of which there can be no
assurance.
