                                   (Unaudited)

(1) The  condensed  balance  sheet as of December 31, 2001 has been derived from
the audited  balance sheet as of that date.  The  condensed  balance sheet as of
June 30,  2002,  the  condensed  statement of  operations  for the three and six
months ended June 30, 2002 and 2001,  and the condensed  statement of cash flows
for the six months  ended June 30, 2002 and 2001 have been  prepared by Cable TV
Fund  12-B,  Ltd.  (the   "Partnership")  and  have  not  been  audited  by  the
Partnership's   independent  auditors.   In  the  opinion  of  management,   all
adjustments  necessary  to present  fairly the  financial  position,  results of
operations and cash flows as of June 30, 2002 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,  2001  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  directly.  The  Partnership  has
continued in existence because of pending litigation in which the Partnership is
a party. It cannot be predicted when the Partnership will be dissolved.

(2) The Partnership  reimburses its general  partner for certain  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 to 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.
Reimbursements made to the general partner by the Partnership for administrative
expenses  for the  three  months  ended  June 30,  2002 and 2001 and for the six
months  ended June 30, 2002 and 2001 were  $7,680,  $3,030,  $10,063 and $7,487,
respectively.

(3) Litigation  Challenging Jones  Intercable's  Acquisitions of the Albuquerque
and Palmdale 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

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.  A  hearing  on the  motion  was  held in  October  2001.  If the
plaintiffs'  motion for class  certification is denied,  the cases would proceed
only as derivative actions.

         The General  Partner  believes that the defendants have defenses to the
plaintiffs'  claims for  relief and  challenges  to the  plaintiffs'  claims for
damages, and the General Partner intends to defend these lawsuits vigorously.

Litigation Relating to Limited Partnership List Requests

         The  Partnership  was a defendant  in a case  captioned  Everest  Cable
Investors, LLC, et al., plaintiffs v. Jones Intercable, Inc., et al., defendants
(Superior  Court, Los Angeles County,  State of California,  Case No. BC 213632)
originally filed in July 1999.  Plaintiffs alleged that certain of them formed a
venture to acquire  limited  partnership  interests in the  Partnership and that
plaintiffs were frustrated in this purpose by Jones Intercable's alleged refusal
to provide  plaintiffs  with a list of the names and  addresses  of the  limited
partners of the Partnership. Plaintiffs alleged that their failure to obtain the
partnership list prevented them from making a tender offer for the Partnership's
limited partnership interests causing them economic loss. None of the plaintiffs
is a limited partner of the  Partnership but one of the plaintiffs  alleged that
it held a power of attorney from a limited partner of the Partnership. The trial
court found that a holder of a power of attorney is not a real party in interest
capable  of suing on the rights of the  principal  and thus  dismissed  the case
against the  Partnership.  The plaintiffs chose not to appeal this ruling of the
trial court and thus the Partnership is no longer a party to this litigation.

expenses until the  Partnership is dissolved.  The  Partnership has continued in
existence because of pending  litigation in which the Partnership is a party. It
cannot be predicted when the Partnership will be dissolved.
