                                    -------

                               ITEM 1.  BUSINESS
                               -----------------

          The Partnership.  Jones Spacelink Income/Growth Fund 1-A, Ltd. (the
"Partnership") is a Colorado limited partnership that was formed pursuant to the
public offering of limited partnership interests in the Jones Spacelink
Income/Growth Fund 1 Limited Partnership Program (the "Program").  Jones
Intercable, Inc., a Colorado corporation, is the general partner of the
Partnership (the "General Partner").  The Partnership was formed for the purpose
of acquiring and operating cable television systems.  The Partnership owned the
cable television systems serving the areas in and around the communities of
Bluffton, Decatur, Monroe, Auburn, Butler, Uniondale, Waterloo, Poneto, Vera
Cruz and Garrett and certain unincorporated areas of Wells, Allen, Noble, Adams
and DeKalb Counties, all in the State of Indiana (the "Northeast Indiana
Systems") until they were sold on June 30, 1998.  See Disposition of Cable
Television System below.

          It is anticipated that Comcast Corporation ("Comcast") will acquire a
controlling interest in the General Partner during April 1999.  As a result of
this transaction, it is expected that the current management of the General
Partner and a majority of the Board of Directors of the General Partner will be
replaced by Comcast.

          Disposition of Cable Television System.  On June 30, 1998, the
Partnership sold its Northeast Indiana Systems to an unaffiliated party for a
sales price of $23,500,000, subject to normal closing adjustments.  From the
sale proceeds, the Partnership repaid all of its indebtedness, including the
$7,500,000 borrowed under its credit facility and capital lease obligations
totaling $120,042, settled working capital adjustments, and then deposited
$1,000,000 into an interest-bearing indemnity escrow account.  The remaining net
sale proceeds of $14,915,500 were distributed in August 1998 to its limited
partners of record as of June 30, 1998.  The distribution from the sale of the
Northeast Indiana Systems provided the Partnership's limited partners, as a
group, $14,915,500, or an approximate return of $291 for each $500 limited
partnership interest, or $582 for each $1,000 invested in the Partnership.  The
sale of the Northeast Indiana Systems was approved by the holders of a majority
of the limited partnership interests in the Partnership.

          Taking into account prior distributions to limited partners from the
Partnership's operating cash flow and from the net proceeds of prior system
sales and the sale of the Northeast Indiana Systems (excluding escrowed
proceeds), the limited partners of the Partnership have received a total return
of $589 for each $500 limited partnership interest, or $1,178 for each $1,000
invested in the Partnership.

          For a period of one year following the closing date of June 30, 1998,
$1,000,000 of the sale proceeds will remain in escrow as security for the
Partnership's agreement to indemnify the buyer under the asset purchase
agreement.  The Partnership's primary exposure, if any, will relate to the
representations and warranties made about the Northeast Indiana Systems in the
asset purchase agreement.  Any amounts remaining in this interest-bearing
indemnity escrow account and not claimed by the buyer at the end of the one-year
period, plus interest earned on the escrowed funds, will be returned to the
Partnership.  From this amount, the Partnership will pay any remaining
liabilities and the Partnership will then distribute the balance to the limited
partners.  The Partnership will continue in existence at least until any amounts
remaining from the indemnity escrow account have been distributed.  Since the
Northeast Indiana Systems represented the only remaining operating asset of the
Partnership, the Partnership will be liquidated and dissolved upon the final
distribution of any amounts remaining from the indemnity escrow account, most
likely in the third quarter of 1999.  If any disputes with respect to the
indemnification arise, the 

                                       2
<PAGE>
 
Partnership would not be dissolved until such disputes were resolved, which
could result in the Partnership continuing beyond 1999.

          Because transferees of limited partnership interests following the
record date for the distribution of the proceeds from the sale of the Northeast
Indiana Systems (June 30, 1998) would not be entitled to any distributions from
the Partnership, a transfer of limited partnership interests following such
record date would have no economic value.  The General Partner therefore has
determined that, pursuant to the authority granted to it by the Partnership's
limited partnership agreement, the General Partner will approve no transfers of
limited partnership interests after June 30, 1998.
                                

                              ITEM 2.  PROPERTIES
                              -------------------

          As of December 31, 1998, the Partnership does not own any cable
television systems.

                      -----------------------------------

          While the Partnership is publicly held, there is no public market for
the limited partnership interests, and it is not expected that a market will
develop in the future.  During 1998, a limited partner of the Partnership
conducted a "limited tender offer" for interests in the Partnership at a price
of $175 per interest. As of February 16, 1999, the number of equity security
holders in the Partnership was 2,153.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
--------------------------------------------------------------------------------
         OF OPERATIONS
         -------------

      The following discussion of the financial condition and results of
operations of Jones Spacelink Income/Growth Fund 1-A, Ltd. (the "Partnership")
contains, in addition to historical information, forward-looking statements that
are based upon certain assumptions and are subject to a number of risks and
uncertainties.  The Partnership's actual results may differ significantly from
the results predicted in such forward-looking statements.

FINANCIAL CONDITION
-------------------

      On June 30, 1998, the Partnership sold its cable television systems
serving the areas in and around the communities of Bluffton, Decatur, Monroe,
Auburn, Butler, Uniondale, Waterloo, Poneto, Vera Cruz and Garrett, and the
unincorporated areas of Wells, Allen, Noble, Adams and DeKalb Counties, all in
the State of Indiana (the "Northeast Indiana Systems") to an unaffiliated party
for a sales price of $23,500,000, subject to normal closing adjustments.  From
the sale proceeds, the Partnership repaid all of its indebtedness, including the
$7,500,000 borrowed under its credit facility and capital lease obligations
totaling $120,042, settled working capital adjustments, and then deposited
$1,000,000 into an interest-bearing indemnity escrow account.  The remaining net
sale proceeds of $14,915,500 were distributed to its limited partners of record
as of June 30, 1998, in August 1998.  The distribution from the sale of the
Northeast Indiana Systems provided the Partnership's limited partners, as a
group, $14,915,500, or an approximate return of $291 for each $500 limited
partnership interest, or $582 for each $1,000 invested in the Partnership.  The
sale of the Northeast Indiana Systems was approved by the holders of a majority
of the limited partnership interests in the Partnership.

     Taking into account prior distributions to limited partners from the
Partnership's operating cash flow and from the net proceeds of prior system
sales and the sale of the Northeast Indiana Systems (excluding escrowed
proceeds), the limited partners of the Partnership have received a total return
of $589 for each $500 limited partnership interest, or $1,178 for each $1,000
invested in the Partnership.

                                       4
<PAGE>
 
      For a period of one year following the closing date of June 30, 1998,
$1,000,000 of the sale proceeds will remain in escrow as security for the
Partnership's agreement to indemnify the buyer under the asset purchase
agreement.  The Partnership's primary exposure, if any, will relate to the
representations and warranties made about the Northeast Indiana Systems in the
asset purchase agreement.  Any amounts remaining in this interest-bearing
indemnity escrow account and not claimed by the buyer at the end of the one-year
period, plus interest earned on the escrowed funds, will be returned to the
Partnership.  From this amount, the Partnership will pay any remaining
liabilities and it will then distribute the balance to the Partnership's limited
partners.  The Partnership will continue in existence at least until any amounts
remaining from the interest-bearing indemnity escrow account have been
distributed.  Since the Northeast Indiana Systems represented the only operating
asset of the Partnership, the Partnership will be liquidated and dissolved upon
the final distribution of any amounts remaining from the interest-bearing
indemnity escrow account, most likely in the third quarter of 1999.

RESULTS OF OPERATIONS
---------------------

     Due to the Northeast Indiana Systems sale on June 30, 1998, which were the
Partnership's last remaining operating assets, a full discussion of the results
of operations would not be comparable. For the year ended December 31, 1998, the
Partnership had total revenues of $2,919,556 and generated an operating loss of
$49,096. Because of the gain of $13,106,602 on the sale of the Northeast Indiana
Systems, the Partnership realized net income of $12,794,204, or $249.18 per
limited partnership unit, in 1998.

Year 2000 Issue
---------------

     The Year 2000 issue is the result of many computer programs being written
such that they will malfunction when reading a year of "00."  This problem could
cause system failure or miscalculations causing disruptions of business
processes.  Due to the Northeast Indiana Systems sale on June 30, 1998, and the
planned liquidation and dissolution of the Partnership in 1999, the Year 2000
issue will not have a material effect on the Partnership.

To the Partners of Jones Spacelink Income/Growth Fund 1-A, Ltd.:

     We have audited the accompanying balance sheets of Jones Spacelink
Income/Growth Fund 1-A, Ltd. (a Colorado limited partnership) as of December 31,
1998 and 1997, and the related statements of operations, partners' capital
(deficit) and cash flows for each of the three years in the period ended
December 31, 1998.  These financial statements are the responsibility of the
General Partner's management.  Our responsibility is to express an opinion on
these financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Jones Spacelink
Income/Growth Fund 1-A, Ltd. as of December 31, 1998 and 1997, and the results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1998, in conformity with generally accepted accounting
principles.

(1)  ORGANIZATION AND PARTNERS' INTERESTS:
     ------------------------------------ 

     Formation and Business
     ----------------------

     Jones Spacelink Income/Growth Fund 1-A, Ltd. (the "Partnership"), a
Colorado limited partnership, was formed on May 12, 1988, pursuant to a public
offering of limited partner interests.  The Partnership was formed to acquire,
construct, develop and operate cable television systems.  Jones Intercable, Inc.
("Intercable"), a Colorado corporation, is the "General Partner," and manager of
the Partnership.  Intercable and certain of its subsidiaries also own and
operate cable television systems for their own account and for the account of
other managed limited partnerships.

     Cable Television System Acquisitions
     ------------------------------------

     In November 1988, the Partnership purchased the cable television systems
serving the areas in and around the communities of Bluffton, Decatur, Monroe,
Auburn, Butler, Uniondale, Waterloo, Poneto, Vera Cruz and Garrett, and the
unincorporated areas of Wells, Allen, Noble, Adams and DeKalb counties, all in
the State of Indiana (the "Northeast Indiana Systems").  Such systems were sold
on June 30, 1998 as discussed below.

     In March 1991, the Partnership purchased the cable television system
serving the communities of Lake Geneva and areas of Walworth County, all in the
State of Wisconsin (the "Lake Geneva System") and the cable television system
serving the communities of Ripon and areas of Fond-du-Lac County, all in the
State of Wisconsin (the "Ripon System").  Such systems were sold in 1996.

     Contributed Capital, Commissions and Syndication Costs
     ------------------------------------------------------

     The capitalization of the Partnership is set forth in the accompanying
statements of partners' capital (deficit).  No limited partner was obligated to
make any additional contribution to Partnership capital.  The General Partner
purchased its general partner interest in the Partnership by contributing $1,000
to partnership capital.

     All profits and losses of the Partnership were allocated 99 percent to the
limited partners and one percent to the General Partner, except for income or
gain from the sale or disposition of cable television properties, which was
allocated to the partners based upon the formula set forth in the partnership
agreement, and interest income earned prior to the first acquisition by the
Partnership of a cable television system, which was allocated 100 percent to the
limited partners.

     Sales of Cable Television Systems
     ---------------------------------

     On June 30, 1998, the Partnership sold its Northeast Indiana Systems to an
unaffiliated party for a sales price of $23,500,000, subject to normal closing
adjustments.  From the sale proceeds, the Partnership repaid all of its
indebtedness, including the $7,500,000 borrowed under its credit facility and
capital lease obligations totaling $120,042, settled working capital
adjustments, and then deposited $1,000,000 into an interest-bearing indemnity
escrow account.  The remaining net sale proceeds of $14,915,500 were distributed
to its limited partners of record as of June 30, 1998, in August 1998.  The
distribution from the sale of the Northeast Indiana Systems provided the
Partnership's limited partners, as a group, $14,915,500, or an approximate
return of $291 for each $500 limited partnership interest, or $582 for each
$1,000 invested in the Partnership.  The sale of the Northeast Indiana Systems
was approved by the holders of a majority of the limited partnership interests
in the Partnership.

     Taking into account prior distributions to limited partners from the
Partnership's operating cash flow and from the net proceeds of prior system
sales and the sale of the Northeast Indiana Systems (excluding escrowed
proceeds), the limited partners of the Partnership have received a total return
of $589 for each $500 limited partnership interest, or $1,178 for each $1,000
invested in the Partnership.

                                       12
<PAGE>
 
     For a period of one year following the closing date of June 30, 1998,
$1,000,000 of the sale proceeds will remain in escrow as security for the
Partnership's agreement to indemnify the buyer under the asset purchase
agreement.  The Partnership's primary exposure, if any, will relate to the
representations and warranties made about the Northeast Indiana Systems in the
asset purchase agreement.  Any amounts remaining in this interest-bearing
indemnity escrow account and not claimed by the buyer at the end of the one-year
period, plus interest earned on the escrowed funds, will be returned to the
Partnership.  From this amount, the Partnership will pay any remaining
liabilities and it will then distribute the balance to the Partnership's limited
partners.  The Partnership will continue in existence at least until any amounts
remaining from the interest-bearing indemnity escrow account have been
distributed.  Since the Northeast Indiana Systems represented the only operating
asset of the Partnership, the Partnership will be liquidated and dissolved upon
the final distribution of any amounts remaining from the interest-bearing
indemnity escrow account, most likely in the third quarter of 1999.

(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
     ------------------------------------------ 

     Accounting Records
     ------------------

     The accompanying financial statements have been prepared on the accrual
basis of accounting in accordance with generally accepted accounting principles.
The Partnership's tax returns are also prepared on the accrual basis.

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

     Property, Plant and Equipment
     -----------------------------

     Depreciation of property, plant and equipment was provided using the
straight-line method over the following estimated service lives:
 
               Cable distribution systems        5 - 15  years
               Equipment and tools               5 -  7  years
               Office furniture and equipment    3 -  5  years
               Buildings                             30  years
               Vehicles                          3 -  4  years

     Replacements, renewals and improvements were capitalized and maintenance
and repairs were charged to expense as incurred.

     Property, plant and equipment and the corresponding accumulated
depreciation were written off as certain assets became fully depreciated and
were no longer in service.

     Intangible Assets
     -----------------

     Costs assigned to intangible assets were amortized using the straight-line
method over remaining estimated useful lives ranging from 2 to 33 years.

     Revenue Recognition
     -------------------

     Subscriber prepayments were initially deferred and recognized as revenue
when earned.

</TABLE>

      The Partnership had an $8,000,000 credit facility, which was paid in full
on June 30, 1998 upon the sale of the Northeast Indiana Systems.  Interest on
the outstanding principal balance was at the Partnership's option of the Prime
Rate plus 1/4 percent or the London Interbank Offered Rate plus 1-1/4 percent.
The effective interest rate on outstanding obligations as of December 31, 1997
was 7.17 percent.

      The Partnership's capital lease obligations were paid in June 1998 from
proceeds from the sale of the Northeast Indiana Systems.

      At December 31, 1997, the carrying amount of the Partnership's long-term
debt did not differ significantly from the estimated fair value of the financial
instruments.  The fair value of the Partnership's long-term debt was estimated
based on the discounted amount of future debt service payments using rates of
borrowing for a liability of similar risk.

(5)  SIGNIFICANT TRANSACTIONS WITH THE GENERAL PARTNER AND AFFILIATES:
     ---------------------------------------------------------------- 

     Management Fees, Distribution Ratios and Reimbursements
     -------------------------------------------------------

     The General Partner managed the Partnership and received a fee for its
services equal to 5 percent of the gross revenues of the Partnership, excluding
revenues from the sale of cable television systems or franchises.  Management
fees paid to the General Partner by the Partnership for the years ended December
31, 1998, 1997 and 1996 were $145,978, $276,140 and $286,227, respectively.  The
General Partner has not received and will not receive a management fee after
June 30, 1998.

     Any partnership distributions made from cash flow (defined as cash receipts
derived from routine operations and interest income, less debt principal and
interest payments and cash expenses) are allocated 99 percent to the limited
partners and one percent to the General Partner.  The Partnership may distribute
any proceeds from the sale or refinancing 

                                       14
<PAGE>
 
of a cable television system generally as follows: first, to the Partners until
they have received an amount equal to their initial capital contributions (as
reduced by all prior distributions other than distributions from cash flow);
second, to the limited partners until they have received a liquidation
preference equal to 12 percent per annum, cumulative and noncompounded, on an
amount equal to their initial capital contributions, less any portion of such
capital contributions which has been returned to the limited partners from prior
sale or refinancing proceeds, as determined for any particular year; provided
that such cumulative return will be reduced by all prior distributions of cash
flow from operations and prior distributions of proceeds of sales or
refinancings of the Partnership's cable television systems. The balance will be
allocated 75 percent to the limited partners' and 25 percent to the General
Partner. See Note 6 for discussion of cash flow distributions.

     The Partnership reimbursed the General Partner and certain of its
subsidiaries for certain allocated overhead and administrative expenses.  These
expenses represented the salaries and related benefits paid for corporate
personnel, rent, data processing services and other corporate facilities costs.
Such personnel provided engineering, marketing, accounting, administrative,
legal, and investor relations services to the Partnership.  Such services, and
their related costs, were necessary to the operation of the Partnership and
would have been incurred by the Partnership if it was a stand alone entity.
Allocations of personnel costs were based primarily on actual time spent by
employees of the General Partner with respect to each entity managed.  Remaining
expenses were allocated based on the pro rata relationship of the Partnership's
revenues to the total revenues of all systems owned or managed by the General
Partner and certain of its subsidiaries.  Systems owned by the General Partner
and all other systems owned by partnerships for which Intercable is the general
partner were also allocated a proportionate share of these expenses.  The
General Partner believes that the methodology used in allocating overhead and
administrative expenses was reasonable.  Reimbursements made to the General
Partner by the Partnership for allocated overhead and administrative expenses
were $181,831, $325,192 and $393,612 for the years ended December 31, 1998, 1997
and 1996, respectively. The Partnership will continue to reimburse the General
Partner for actual time spent on Partnership business by employees of the
General Partner until the Partnership is liquidated and dissolved, but the
Partnership will not bear a revenue-based allocation of overhead and
administrative expenses beyond June 30, 1998.

     The Partnership was charged interest during 1998 at an average interest
rate of approximately 7.05 percent per annum on the amounts due the General
Partner, which approximated the General Partner's weighted average cost of
borrowing.  Total interest charged to the Partnership by the General Partner was
$17,600, $2,796 and $67,530 for the years ended December 31, 1998, 1997 and
1996, respectively.

     Payments to/from Affiliates for Programming Services
     ----------------------------------------------------

     The Partnership received programming from Superaudio, Knowledge TV, Inc.,
Jones Computer Network, Ltd., Great American Country, Inc. and Product
Information Network, all of which are affiliates of the General Partner.

     Payments to Superaudio by the Partnership for the years ended December 31,
1998, 1997 and 1996 totaled $5,345, $9,775 and $9,979, respectively.  Payments
to Knowledge TV, Inc. by the Partnership for the years ended December 31, 1998,
1997 and 1996 totaled $6,025, $10,870 and $10,882, respectively.  Payments to
Jones Computer Network, Ltd., whose service was discontinued in April 1996,
totaled $1,557 for the year ended December 31, 1996.  Payments to Great American
Country, Inc. totaled $5,891, $11,313 and $3,039 in 1998, 1997 and 1996,
respectively.

     The Partnership received a commission from Product Information Network,
based on a percentage of advertising revenue and number of subscribers.  Product
Information Network paid commissions to the Partnership for the years ended
December 31, 1998, 1997 and 1996 totaling $12,420, $18,248, $12,295,
respectively.

(6)  DISTRIBUTIONS FROM CASH FLOW:
     ---------------------------- 

     A primary objective of the Partnership was to provide quarterly cash
distributions to the partners, principally from cash flow from operations
remaining after principal and interest payments and the creation of any reserves
necessary for the operation of the Partnership.  The Partnership made no such
distributions in 1998 and 1997 because funds from cash flow were used to pay for
necessary capital additions to the Northeast Indiana Systems as a result of
limited borrowing capacity under the Partnership's credit facility.  The
Partnership declared such distributions totaling $1,262,626 in 1996.

                                       15
<PAGE>
 
(7)  COMMITMENTS AND CONTINGENCIES:
     ----------------------------- 

     For a period of one year following the Northeast Indiana Systems closing
date of June 30, 1998, $1,000,000 of the sale proceeds will remain in escrow as
security for the Partnership's agreement to indemnify the buyer under the asset
purchase agreement. The Partnership's primary exposure, if any, will relate to
the representations and warranties made about the Northeast Indiana Systems in
the asset purchase agreement. Any amounts remaining in this interest-bearing
indemnity escrow account and not claimed by the buyer at the end of the one-year
period, plus interest earned on the escrowed funds, will be returned to the
Partnership. From this amount, the Partnership will pay any remaining
liabilities and it will then distribute the balance to the Partnership's limited
partners.

(8)  INCOME TAXES:
     ------------ 

     Income taxes have not been recorded in the accompanying financial
statements because they accrue directly to the partners.  The federal and state
income tax returns of the Partnership are prepared and filed by the General
Partner.

     The Partnership's tax returns, the qualification of the Partnership as such
for tax purposes, and the amount of distributable income or loss are subject to
examination by federal and state taxing authorities.  If such examinations
result in changes with respect to the Partnership's qualification as such, or in
changes with respect to the Partnership's recorded income or loss, the tax
liability of the general and limited partners would likely be changed
accordingly.

     Taxable income (loss) to the Partners is different from that reported in
the statements of operations due to the difference in depreciation recognized
under generally accepted accounting principles and the expense allowed for tax
purposes under the Modified Accelerated Cost Recovery System (MACRS).  There are
no other significant differences between taxable income (loss) and the net
income reported in the statements of operations.

                        ITEM 11.  EXECUTIVE COMPENSATION
                        --------------------------------

          The Partnership has no employees; however, various personnel were
required to operate the systems. Such personnel were employed by the General
Partner and, pursuant to the terms of the limited partnership agreement of the
Partnership, the cost of such employment was charged by the General Partner to
the Partnership as a direct reimbursement item. See Item 13.


     ITEM 12.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGERS
     ----------------------------------------------------------------------

          As of February 16, 1999, no person or entity owned more than 5 percent
of the limited partnership interests of the Partnership.


            ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
            --------------------------------------------------------

          Prior to selling the Partnership's Northeast Indiana Systems on June
30, 1998, the General Partner and its affiliates engaged in certain transactions
with the Partnership as contemplated by the limited partnership agreement of the
Partnership. The General Partner believes that the terms of such transactions
were generally as favorable as could be obtained by the Partnership from
unaffiliated parties. This determination has been made by the General Partner in
good faith, but none of the terms were negotiated at arm's-length and there can
be no assurance that the terms of such transactions have been as favorable as
those that could have been obtained by the Partnership from unaffiliated
parties. Following the sale of the Northeast Indiana Systems on June 30, 1998,
the General Partner does not anticipate engaging in such transactions.

Transactions with the General Partner

          The General Partner manages the Partnership and until June 30, 1998,
the date of the sale of the Partnership's last remaining cable television
system, the General Partner received a fee for its services equal to 5 percent
of the gross revenues of the Partnership, excluding revenues from the sale of
cable television systems or franchises. The General Partner has not received a
management fee after June 30, 1998.

          The Partnership reimbursed the General Partner for certain allocated
overhead and administrative expenses.  These expenses represented the salaries
and benefits paid to corporate personnel, rent, data processing services and
other corporate facilities costs.  Such personnel provided engineering,
marketing, administrative, accounting, legal and investor relations services to
the Partnership.  Such services, and their related costs, were necessary to the
operations of the Partnership and would have been incurred by the Partnership if
it was a stand alone entity.  Allocations of personnel costs were based
primarily on actual time spent by employees of the General Partner with respect
to each partnership managed.  Remaining expenses were allocated based on the pro
rata relationship of the Partnership's revenues to the total revenues of all
systems owned or managed by the General Partner and certain of its subsidiaries.
Systems owned by the General Partner and all other systems owned by partnerships
for which Jones Intercable, Inc. is the general partner were also allocated a
proportionate share of these expenses.  The Partnership will continue to
reimburse the General Partner for actual time spent on Partnership business by
employees of the General Partner until the Partnership is liquidated and
dissolved, but the Partnership will not bear a revenue-based allocation of
overhead and administrative expenses beyond June 30, 1998.

          The General Partner from time to time advanced funds to the
Partnership and charged interest on the balance payable. The interest rate
charged approximated the General Partner's weighted average cost of borrowing.

Transactions with Affiliates

          Jones International, Ltd. ("International"), a company owned by Glenn
R. Jones, and certain of its subsidiaries have provided various services to the
Partnership, including affiliation agreements for the distribution

                                       21
<PAGE>
 
of programming owned by affiliated companies on cable television systems owned
by the Partnership, as described below.

          Until June 30, 1998, the date of the Partnership's sale of the
Northeast Indiana Systems, the Partnership engaged in transactions with the
following affiliates:

          Knowledge TV, Inc., a company jointly owned by Mr. Jones, affiliates
of International, the General Partner and BCI Telecom Holdings Inc., a principal
shareholder of the General Partner, operates the television network Knowledge
TV. Knowledge TV provides programming related to computers and technology;
business, careers and finance; health and wellness; and global culture and
languages.

          The Great American Country network provided country music video
programming to the Northeast Indiana Systems. This network is owned and operated
by Great American Country, Inc., a subsidiary of Jones International Networks,
Ltd., an affiliate of the General Partner.

          Jones Galactic Radio, Inc. is a subsidiary of Jones International
Networks, Ltd., an affiliate of the General Partner. Superaudio, a joint venture
between Jones Galactic Radio, Inc. and an unaffiliated entity, provided audio
programming to the Northeast Indiana Systems.

          The Product Information Network Venture (the "PIN Venture") is a
venture among a subsidiary of Jones International Networks, Ltd., an affiliate
of the General Partner, and two unaffiliated cable system operators. The PIN
Venture operates the Product Information Network ("PIN"), which is a 24-hour
network that airs long-form advertising generally known as "infomercials." The
PIN Venture generally makes incentive payments of approximately 60 percent of
its net advertising revenue to the cable systems that carry its programming. The
Partnership's Northeast Indiana Systems carried PIN for all or part of each day.
Revenues received by the Partnership from the PIN Venture relating to the
Northeast Indiana Systems totaled approximately $12,420 for the year ended
December 31, 1998.

          The charges to the Partnership for related party transactions were as
follows for the periods indicated:
