                     NOTES TO CONDENSED FINANCIAL STATEMENTS

                     ========================================


1.       INTERIM FINANCIAL STATEMENTS

         The accompanying condensed interim financial statements for the three
and six months ended June 30, 1997 and 1996 are unaudited. These condensed
interim financial statements should be read in conjunction with the audited
financial statements and notes thereto included in the Partnership's latest
Annual Report on Form 10-K. In the opinion of management, such 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 and six months ended June 30, 1997 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 with a wholly
owned subsidiary of the Corporate General Partner (the "Manager") for a monthly
management fee of 5% of revenues, excluding revenues from the sale of cable
television systems or franchises. Management fee expense approximated $37,400
and $74,300 for the three and six months ended June 30, 1997.

         In addition to the monthly management fee described above, the
Partnership reimburses the Manager for direct expenses incurred on behalf of the
Partnership and for the Partnership's allocable share of operational costs
associated with services provided by the Manager. All cable television
properties managed by the Corporate General Partner and its subsidiary are
charged a proportionate share of these expenses. Corporate office allocations
and district office expenses are charged to the properties served based
primarily on the respective percentage of basic subscribers or homes passed
(dwelling units within a system) within the designated service areas. The total
amount charged to the Partnership for these services approximated $80,900 and
$156,200 for the three and six months ended June 30, 1997. Management fees and
reimbursed expenses due the Corporate General Partner are non-interest bearing.

         Certain programming services have been purchased through an affiliate
of the Partnership. In turn, the affiliate charges the Partnership for these
costs based on an estimate of what the Corporate General Partner could negotiate
for such programming services for the 15 partnerships managed by the Corporate
General Partner as a group. The Partnership recorded programming fee expense of
$153,700 and $303,200 for the three and six months ended June 30, 1997.
Programming fees are included in service costs in the statements of operations.

3.       EARNINGS PER UNIT OF LIMITED PARTNERSHIP INTEREST

         Earnings and losses per unit of limited partnership interest is based
on the average number of units outstanding during the periods presented. For
this purpose, earnings and losses have 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.

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

INTRODUCTION

         On February 8, 1996, President Clinton signed into law the
Telecommunications Act of 1996 (the "1996 Telecom Act"). This statute
substantially changed the competitive and regulatory environment for
telecommunications providers by significantly amending the Communications Act of
1934, including certain of the rate regulation provisions previously imposed by
the Cable Television Consumer Protection and Competition Act of 1992 (the "1992
Cable Act"). Compliance with those rate regulations has had a negative impact on
the Partnership's revenues and cash flow. The 1996 Telecom Act provides that
certain of the rate regulations will be phased out altogether in 1999. Further,
the regulatory environment will continue to change pending, among other things,
the outcome of legal challenges and Federal Communications Commission (the
"FCC") rulemaking and enforcement activity in respect of the 1992 Cable Act and
the 1996 Telecom Act. There can be no assurance as to what, if any, further
action may be taken by the FCC, Congress or any other regulatory authority or
court, or the effect thereof on the Partnership's business. Accordingly, the
Partnership's historical financial results as described below are not
necessarily indicative of future performance.

         This Report includes certain forward looking statements regarding,
among other things, future results of operations, regulatory requirements,
competition, capital needs and general business conditions applicable to the
Partnership. 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 the Partnership. In addition to the information
provided herein, reference is made to the Partnership's Annual Report on Form
10-K for the year ended December 31, 1996 for additional information regarding
such matters and the effect thereof on the Partnership's business.

RESULTS OF OPERATIONS

         The Partnership's revenues increased from $666,500 to $748,100, or by
12.2%, and from $1,316,200 to $1,486,200, or by 12.9%, for the three and six
months ended June 30, 1997 as compared to the corresponding periods in 1996. Of
the $81,600 increase in revenues for the three months ended June 30, 1997 as
compared to the corresponding period in 1996, $47,900 was due to increases in
regulated service rates that were implemented by the Partnership in the second
and fourth quarters of 1996, $23,800 was due to the restructuring of The Disney
Channel from a premium channel to a tier channel effective July 1, 1996 and
$9,400 was due to increases in other revenue producing items. Of the $170,000
increase in revenues for the six months ended June 30, 1997 compared to the
corresponding period in 1996, $112,400 was due to increases in regulated service
rates, $47,100 was due to the restructuring of The Disney Channel and $16,300
was due to increases in other revenue producing items. These increases were
partially offset by a decrease of $5,800 due to decreases in the number of
subscriptions, primarily for premium service. As of June 30, 1997, the
Partnership had approximately 7,000 homes subscribing to cable service and 1,700
premium service units.

RESULTS OF OPERATIONS (CONTINUED)

         Service costs increased from $190,800 to $218,900, or by 14.7%, and
from $390,300 to $432,700, or by 10.9%, for the three and six months ended June
30, 1997 as compared to the corresponding periods in 1996. Service costs
represent costs directly attributable to providing cable services to customers.
Programming expense accounted for the majority of the increase in both periods.
Programming expense increased primarily as a result of higher rates charged by
program suppliers.

         General and administrative expenses decreased from $79,000 to $70,200,
or by 11.1%, and from $170,600 to $119,000, or by 30.2%, for the three and six
months ended June 30, 1997 as compared to the corresponding periods in 1996. The
decreases for the three and six months were primarily due to lower personnel
costs. The decrease for the six months was also due to lower insurance premiums,
professional fees and bad debt expense. Personnel costs decreased due to the
transfer of certain employees to the Corporate General Partner's operations.

         Management fees and reimbursed expenses increased from $94,800 to
$118,300, or by 24.8%, and from $179,400 to $230,500, or by 28.5%, for the three
and six months ended June 30, 1997 as compared to the corresponding periods in
1996. Management fees increased in direct relation to increased revenues as
described above. Reimbursable expenses increased primarily due to higher
allocated personnel costs resulting from the transfer of personnel to the
Corporate General Partner's staff from the Partnership's operations.

         Operating income before income taxes, depreciation and amortization
(EBITDA) is a commonly used financial analysis tool for measuring and comparing
cable television companies in several areas, such as liquidity, operating
performance and leverage. EBITDA as a percentage of revenues increased from
45.3% to 45.5% and from 43.8% to 47.4% during the three and six months ended
June 30, 1997 compared to the corresponding periods in 1996. The change was
primarily due to higher revenues. EBITDA increased from $301,900 to $340,700, or
by 12.9%, and from $575,900 to $704,000, or by 22.2%, during the three and six
months ended June 30, 1997 compared to the corresponding periods in 1996. EBITDA
should be considered in addition to and not as a substitute for net income and
cash flows determined in accordance with generally accepted accounting
principles as an indicator of financial performance and liquidity.

         Depreciation and amortization expense decreased from $84,800 to
$70,800, or by 16.5%, and from $181,900 to $140,700, or by 22.6%, for the three
and six months ended June 30, 1997 as compared to the corresponding periods in
1996, primarily due to certain plant assets becoming fully depreciated in 1996.
Depreciation and amortization expense will increase significantly in future
periods as system rebuilds, which are under construction, are placed into
service.

         Operating income increased from $217,100 to $269,900, or by 24.3%, and
from $394,000 to $563,300, or by 43.0%, for the three and six months ended June
30, 1997 as compared to the corresponding periods in 1996, principally due to
increases in revenues as described above.

RESULTS OF OPERATIONS (CONCLUDED)

         Interest income increased from $30,600 to $39,100, or by 27.8%, and
from $58,800 to $74,300, or by 26.4%, for the three and six months ended June
30, 1997 as compared to the corresponding periods in 1996. These increases were
primarily due to a change in investment policy that yielded a greater return on
invested cash. Interest income also increased due to higher cash balances
available for investment.

         Due to the factors described above, the Partnership's net income
increased from $247,600 to $306,100, or by 23.6%, and from $451,300 to $644,800,
or by 42.9%, for the three and six months ended June 30, 1997 as compared to the
corresponding periods in 1996.

LIQUIDITY AND CAPITAL RESOURCES

         The Partnership's primary objective, having invested its net offering
proceeds in cable systems, is to distribute to its partners all available cash
flow from operations and proceeds from the sale of cable systems, if any, after
providing for expenses and capital requirements relating to the expansion,
improvement and upgrade of its cable systems.

         At June 30, 1997, the Partnership had no debt outstanding. The
Partnership relies upon cash flow from operations to meet operating requirements
and fund necessary capital expenditures. Although the Partnership currently has
a significant cash balance, there can be no assurance that the Partnership's
cash flow will be adequate to meet its future liquidity requirements. The
Partnership is required to rebuild its Taylorville, Illinois cable system at an
estimated total cost of $2,490,000 as a condition of its franchise agreement and
is also rebuilding portions of its cable systems in surrounding communities at
an estimated additional cost of approximately $789,000. Rebuild construction
began in October 1996 and is expected to be completed in the second half of
1997. The Partnership has budgeted expenditures of $2,460,000 in 1997 to
complete the entire rebuild. Construction costs related to the rebuild
approximated $849,000 during the first half of 1997. Other capital expenditures
budgeted for 1997 include approximately $471,000 for the improvement and upgrade
of other assets. As a result, the Partnership intends, if possible, to maintain
cash reserves. In the future, the Partnership may also need to borrow.

         The Corporate General Partner has engaged in discussions with a number
of possible financing sources regarding the availability and terms of a bank
facility for the Partnership. These discussions have to date not been
successful. The Corporate General Partner has generally been advised that an
individual facility of the size needed by the Partnership is too small to
interest most banks which lend to the cable television industry. Accordingly, on
June 6, 1997, the Corporate General Partner and an affiliated partnership formed
Enstar Finance Company, LLC ("EFC"). The Corporate General Partner's objective
is to have EFC obtain a secured bank facility of up to $35 million in order to
provide funds that would in turn be advanced to the Partnership and certain of
the other related partnerships managed by the Corporate General Partner. Such
funds would be used to provide capital to fund future rebuild and upgrade
requirements. Based on discussions with prospective lenders, the Corporate
General Partner believes that this structure, if implemented, will provide
capital to the Partnership on terms more favorable than could be obtained on a
"stand-alone" basis. Any advances by EFC will be independently collateralized by
the individual partnership borrowers so that no partnership will be required to
accept responsibility for borrowings made to other partnerships. The Corporate
General Partner has received a commitment letter from two agent banks


                                      -9-

LIQUIDITY AND CAPITAL RESOURCES (CONCLUDED)

regarding the terms of a bank facility for EFC, although a definitive credit
agreement has not been executed as of the date of this Report. The Corporate
General Partner presently expects the EFC facility to be completed in the third
quarter and, accordingly, contemplates that a loan will be made by EFC to the
Partnership if the Partnership needs to borrow to meet its liquidity
requirements.

         The Partnership paid distributions totaling $94,500 and $189,000 during
the three and six months ended June 30, 1997, and expects to continue to pay
distributions at this level during the remainder of 1997. There can, however, be
no assurances regarding the level, timing or continuation of future
distributions.

         SIX MONTHS ENDED JUNE 30, 1997 AND 1996

         Cash provided by operating activities increased by $592,900 from
$612,800 to $1,205,700 for the six months ended June 30, 1997 as compared with
the corresponding period in 1996. The Partnership used $408,900 less cash to pay
liabilities owed to affiliates and third party creditors during the six months
ended June 30, 1997 compared with the first six months of 1996 due to
differences in the timing of payments. Cash generated by Partnership operations
increased by $153,000 after adding back non-cash depreciation and amortization
charges and gain on sale of cable assets. Receivables and prepaid expenses used
$31,000 less cash in the six months ended June 30, 1997 due to differences in 
the timing of receivable collections and payment of prepaid expenses.

         The Partnership used $823,500 more cash in investing activities in the
six months ended June 30, 1997 than in the corresponding six months of 1996, due
to an $819,100 increase in expenditures for tangible assets, partially offset by
a $4,600 decrease in expenditures for intangible assets. The Partnership
received proceeds of $9,000 in the first half of 1996 related to the sale of
equipment and other assets.

INFLATION

         Certain of the Partnership's expenses, such as those for wages and
benefits, equipment repair and replacement, and billing and marketing generally
increase with inflation. However, the Partnership does not believe that its
financial results have been, or will be, adversely affected by inflation in a
material way.
