                                   (Unaudited)

(1) The  condensed  balance  sheet as of December 31, 2002 has been derived from
the audited  balance sheet as of that date.  The  condensed  balance sheet as of
September 30, 2003, the condensed statement of operations for the three and nine
months ended  September 30, 2003 and 2002,  and the condensed  statement of cash
flows for the nine months ended  September 30, 2003 and 2002 are  unaudited.  In
the opinion of  management,  all  adjustments  necessary  to present  fairly the
financial  position,  results of  operations  and cash flows as of September 30,
2003 and for all periods presented have been made.

         Certain  information  and note  disclosures  normally  included  in the
Partnership's annual financial statements prepared in accordance with accounting
principles  generally  accepted  in the United  States  have been  condensed  or
omitted. These condensed financial statements should be read in conjunction with
the  financial  statements  and  notes  thereto  included  in the  Partnership's
December  31,  2002  Annual  Report on Form 10-K filed with the  Securities  and
Exchange Commission. The results of operations for the interim periods presented
are not necessarily indicative of operating results for the full year.

         The  Partnership  owns no properties.  The Partnership has continued in
existence because of pending litigation to which the Partnership is a party (see
Note 3).

(2) The  Partnership  reimburses  its  general  partner  for  certain  allocated
administrative  expenses.  These  expenses  represent  the  salaries and related
benefits paid for corporate  personnel.  Such personnel provide  administrative,
accounting, tax, legal and investor relations services to the Partnership.  Such
services,  and their related costs, are necessary for the  administration of the
Partnership  until the  Partnership is dissolved.  Such charges were included in
administrative  expenses and other, net in the accompanying  condensed statement
of operations.  Administrative  expenses  allocated to the  Partnership  for the
three  months  ended  September  30, 2003 and 2002 and for the nine months ended
September 30, 2003 and 2002 were $618, $2,551, $1,854 and $2,551, respectively.

Litigation Challenging Jones Intercable's Acquisitions of Certain Cable Systems

         In  June  1999,  Jones  Intercable  was  named  a  defendant  in a case
captioned City  Partnership  Co.,  derivatively on behalf of Cable TV Fund 12-C,
Ltd.,  Cable TV Fund 12-D, Ltd. and Cable TV Fund 12-BCD  Venture,  plaintiff v.
Jones  Intercable,  Inc.,  defendant and Cable TV Fund 12-C, Ltd., Cable TV Fund
12-D, Ltd. and Cable TV Fund 12- BCD Venture,  nominal defendants (U.S. District
Court,   District  of  Colorado,   Civil  Action  No.   99-WM-1155)  (the  "City
Partnership"  case) brought by City  Partnership  Co., a limited  partner of the
named  partnerships.  The plaintiff's  complaint  alleges that Jones  Intercable
breached its fiduciary  duty to the plaintiff and to the other limited  partners
of the  partnerships and to the Venture in connection with the Venture's sale of
the Palmdale,  California cable communications system (the "Palmdale System") to
a subsidiary of Jones  Intercable in December 1998.  The complaint  alleges that
Jones Intercable  acquired the Palmdale System at an unfairly low price that did
not accurately  reflect the market value of the Palmdale  System.  The plaintiff
also  alleges  that the proxy  solicitation  materials  delivered to the limited
partners  of the  partnerships  in  connection  with the  votes  of the  limited
partners on the Venture's sale of the Palmdale System  contained  inadequate and
misleading  information  concerning the fairness of the  transaction,  which the
plaintiff  claims caused Jones Intercable to breach its fiduciary duty of candor
to the limited  partners and which the  plaintiff  claims  constituted  acts and
omissions in violation of Section 14(a) of the Securities  Exchange Act of 1934,
as amended. Plaintiff also claims that Jones Intercable breached the contractual
provision of the partnerships' limited partnership agreements requiring that the
sale  price  be  determined  by  the  average  of  three  separate,  independent
appraisals,   challenging   both  the  independence  and  the  currency  of  the
appraisals. The complaint finally seeks declaratory injunctive relief to prevent
Jones  Intercable  from making use of the  partnerships'  funds to finance Jones
Intercable's defense of this litigation.

         In  August  1999,  Jones  Intercable  was named a  defendant  in a case
captioned  Gramercy  Park  Investments,  LP,  Cobble  Hill  Investments,  LP and
Madison/AG  Partnership Value Partners II, plaintiffs v. Jones Intercable,  Inc.
and Glenn R.  Jones,  defendants,  and Cable TV Fund 12-B,  Ltd.,  Cable TV Fund
12-C, Ltd., Cable TV Fund 12-D, Ltd., Cable TV Fund 14-A, Ltd. and Cable TV Fund
14-B, Ltd., nominal defendants (U.S. District Court, District of Colorado, Civil
Action  No.  99-B-1508)  (the  "Gramercy  Park"  case)  brought  as a class  and
derivative action by limited partners of the named partnerships. The plaintiffs'
complaint  alleges that the defendants  made false and misleading  statements to
the  limited  partners  of  the  named   partnerships  in  connection  with  the
solicitation  of proxies and the votes of the  limited  partners on the sales of
the Palmdale System,  the Albuquerque,  New Mexico cable  communications  system
(the  "Albuquerque  System"),  the Littlerock,  California cable  communications
system  (the  "Littlerock  System")  and  the  Calvert  County,  Maryland  cable
communications system (the "Calvert County System") by the named partnerships to
Jones  Intercable or one of its  subsidiaries in violation of Sections 14 and 20
of the Securities Exchange Act of 1934, as amended. The plaintiffs  specifically
allege that the proxy statements delivered to the limited partners in connection
with the  limited  partners'  votes on these sales were  false,  misleading  and
failed to disclose  material  facts  necessary to make the  statements  made not
misleading.  The plaintiffs' complaint also alleges that the defendants breached
their  fiduciary  duties to the plaintiffs and to the other limited  partners of
the named  partnerships  and to the named  partnerships  in connection  with the
various sales of the Albuquerque  System,  the Palmdale  System,  the Littlerock
System and the Calvert County System to  subsidiaries of Jones  Intercable.  The
complaint  alleges that Jones  Intercable  acquired  these cable  communications
systems at unfairly low prices that did not accurately reflect the market values
of the  systems.  The  plaintiffs  seek on their own behalf and on behalf of all
other limited partners  compensatory and nominal damages, the costs and expenses
of the  litigation,  including  reasonable  attorneys'  and experts'  fees,  and
punitive and exemplary damages.

         In September  1999,  Jones  Intercable  was named a defendant in a case
captioned Mary Schumacher,  Charles McKenzie and Geraldine Lucas,  plaintiffs v.
Jones  Intercable,  Inc. and Glenn R. Jones,  defendants and Cable TV Fund 12-B,
Ltd.,  Cable TV Fund 12-C,  Ltd.,  Cable TV Fund 12-D, Ltd., Cable TV Fund 14-A,
Ltd. and Cable TV Fund 14-B,  Ltd.,  nominal  defendants  (U.S.  District Court,
District of Colorado,  Civil Action No. 99-WM-1702)  ("Schumacher") brought as a
class and derivative action by three limited partners of the named partnerships.
The  substance  of  the  Schumacher  plaintiffs'  complaint  is  similar  to the
allegations raised in the Gramercy Park case.

         In September  1999,  Jones  Intercable  was named a defendant in a case
captioned Robert Margolin, Henry Wahlgren and Joan Wahlgren, plaintiffs v. Jones
Intercable,  Inc. and Glenn R. Jones,  defendants and Cable TV Fund 12-B,  Ltd.,
Cable TV Fund 12-C, Ltd., Cable TV Fund 12-D, Ltd., Cable TV Fund 14-A, Ltd. and
Cable TV Fund 14-B, Ltd., nominal defendants (U.S.  District Court,  District of
Colorado,  Civil  Action  No.  99-B-1778)  ("Margolin")  brought  as a class and
derivative  action by three  limited  partners  of the named  partnerships.  The
substance of the Margolin  plaintiffs'  complaint is similar to the  allegations
raised in the Gramercy Park case.

         In November 1999, the United States  District Court for the District of
Colorado  entered  an order  consolidating  all of the cases  challenging  Jones
Intercable's acquisitions of the Albuquerque,  Palmdale,  Littlerock and Calvert
County Systems because these cases involve common questions of law and fact. The
cases are  presented as both class and  derivative  actions.  In June 2001,  the
plaintiffs filed a motion for class  certification.  In August 2001, the General
Partner  filed  a  brief  in  opposition   to   plaintiffs'   motion  for  class
certification.  In September 2002, the court granted the plaintiffs'  motion for
class certification.

         On June 25, 2003,  the parties  agreed to the terms of a settlement  of
this litigation and entered into a written settlement  agreement,  and notice of
the settlement was sent to the limited partners on August 5, 2003. Because these
are class and derivative actions,  the settlement must be approved by the court.
On  October  14,  2003,  the judge  issued a  Recommendation  of  United  States
Magistrate  Judge,  in which he recommended to the United States  District Court
judge that the settlement be approved.  If the District Court judge accepts this
recommendation and approves the settlement,  the General Partner,  within thirty
(30) days of such approval,  will cause the Partnership to distribute,  pursuant
to the  distribution  provisions  of the Limited  Partnership  Agreement  of the
Partnership, the proceeds received by the Partnership from the settlement.

                                   (Unaudited)

         If and when the settlement is finally  approved,  the Partnership  will
then be  dissolved,  although  no  assurance  can be  given  regarding  when the
dissolution will take place.

         All amounts to be paid as a result of the  litigation  described  above
are the responsibility of the General Partner,  subject to  indemnification  and
other  rights  of the  General  Partner  pursuant  to the  terms of the  limited
partnership agreement.
