                           ------------------------
                            (A Limited Partnership)

                    NOTES TO UNAUDITED FINANCIAL STATEMENTS
                    ---------------------------------------

(1)     This Form 10-Q is being filed in conformity with the SEC requirements
for unaudited financial statements and does not contain all of the necessary
footnote disclosures required for a complete presentation of the Balance Sheets
and Statements of Operations and Cash Flows in conformity with generally
accepted accounting principles. However, in the opinion of management, this data
includes all adjustments, consisting only of normal recurring accruals,
necessary to present fairly the financial position of Cable TV Fund 14-B, Ltd.
(the "Partnership") at September 30, 2000 and December 31, 1999, its Statements
of Operations for the three and nine month periods ended September 30, 2000 and
1999 and its Statements of Cash Flows for the nine month periods ended September
30, 2000 and 1999. Certain prior period amounts have been reclassified to
conform to the 2000 presentation.

        The Partnership has sold all of its cable television systems. 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.

        On April 7, 1999, Comcast Corporation ("Comcast") completed the
acquisition of a controlling interest in Jones Intercable, Inc. ("Jones
Intercable"), the Partnership's general partner until March 2, 2000. In December
1999, Comcast and Jones Intercable entered into a definitive merger agreement
pursuant to which Comcast agreed to acquire all of the outstanding shares of
Jones Intercable not yet owned by Comcast. On March 2, 2000, Jones Intercable
was merged with and into Comcast JOIN Holdings, Inc., a wholly owned subsidiary
of Comcast. As a result of this transaction, Jones Intercable no longer exists
and Comcast JOIN Holdings, Inc. continued as the surviving corporation of the
merger. On August 1, 2000 Comcast JOIN Holdings, Inc. was merged with and into
Comcast Cable Communications, Inc. ("Comcast Cable"), another wholly owned
subsidiary of Comcast. Comcast Cable is now the general partner of the
Partnership. References in these Notes to "the General Partner" refer to
Comcast Cable. The General Partner shares corporate offices with Comcast at
1500 Market Street, Philadelphia, Pennsylvania 19102-2148.

(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 costs were charged to
operating costs during the periods that the Partnership operated its cable
television systems. Subsequent to the sale of the Partnership's final cable
television system, such costs were charged to other expense. Reimbursements
made to the general partner by the Partnership for overhead and administrative
expenses for the three and nine month periods ended September 30, 2000 were
$25,970 and $92,500, respectively, compared to $19,410 and $69,970,
respectively, for the three and nine month periods ended September 30, 1999.

when the Partnership will be dissolved.

 expense of $150,730 incurred in the first nine months of 2000 related to
