                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (Unaudited)

(1) The condensed  balance sheet as of December 31, 2001 has been condensed from
the audited  balance sheet as of that date.  The  condensed  balance sheet as of
March 31, 2002 and the condensed  statements of operations and of cash flows for
the three  months  ended March 31, 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 March 31,  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 period ended March 31,
2002 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  during the three  months ended March 31, 2002 and 2001 were $2,383 and
$4,457, respectively.

cannot be predicted when the Partnership will be dissolved.
