             NOTES TO UNAUDITED CONSOLIDATED 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 March 31, 1999 and December 31, 1998 and its Statements
of Operations and Cash Flows for the three month periods ended March 31, 1999
and 1998.

         The Partnership is a Colorado limited partnership that was formed
pursuant to the public offering of limited partnership interests in the Cable TV
Fund 14 Limited Partnership Program (the "Program"), which was sponsored by
Jones Intercable, Inc. (the "General Partner"), to acquire, own and operate
cable television systems in the United States. Cable TV Fund 14-A, Ltd. ("Fund
14-A") is the other partnership that was formed pursuant to the Program. The
Partnership owned the cable television system serving Littlerock, California
(the "Littlerock System") until its sale on January 29, 1999. The Partnership
owned the cable television system serving Surfside, South Carolina (the
"Surfside System") until its sale on June 30, 1998. The Partnership also owned a
73 percent interest in Cable TV Fund 14-A/B Venture (the "Venture"). The
Venture sold its only asset, the cable television system serving certain areas
in Broward County, Florida (the "Broward System"), on March 31, 1998, and the
Venture was liquidated and dissolved in October 1998. The accompanying financial
statements historically include 100 percent of the accounts of the Partnership
and those of the Venture, reduced by the 27 percent minority interest in the
Venture owned by Fund 14-A. All interpartnership accounts and transactions have
been eliminated.

         On April 7, 1999, Comcast Corporation ("Comcast") completed the
acquisition of a controlling interest in the General Partner. Comcast now owns
approximately 12.8 million shares of the General Partner's Class A Common Stock
and approximately 2.9 million shares of the General Partner's Common Stock,
representing approximately 37% of the economic interest and 47% of the voting
interest in the General Partner. Also on that date, Comcast contributed its
shares in the General Partner to Comcast's wholly owned subsidiary, Comcast
Cable Communications, Inc. ("Comcast Cable"). The approximately 2.9 million
shares of Common Stock of the General Partner owned by Comcast represents
approximately 57% of the outstanding Common Stock, which class of stock is
entitled to elect 75% of the Board of Directors of the General Partner. As a
result of this transaction, the General Partner is now a consolidated public
company subsidiary of Comcast Cable.

         Also on April 7, 1999, the bylaws of the General Partner were amended
to establish the size of the General Partner's Board of Directors as a range
from eight to thirteen directors and the board was reconstituted so as to have
eight directors and the following directors of the General Partner resigned:
Robert E. Cole, Josef J. Fridman, James J. Krejci, James B. O'Brien, Raphael M.
Solot, Robert Kearney, Howard O. Thrall, Siim Vanaselja, Sanford Zisman and
Glenn R. Jones. In addition, Donald L. Jacobs resigned as a director elected by
the holders of Class A Common Stock and was elected by the remaining directors
as a director elected by the holders of Common Stock. The remaining directors
elected the following persons to fill the vacancies on the board created by such
resignations: Ralph J. Roberts, Brian L. Roberts, John R. Alchin, Stanley Wang
and Lawrence S. Smith. All of the newly elected directors, with the exception of
Mr. Jacobs, are officers of Comcast. Also on April 7, 1999, the following
executive officers of the General Partner resigned: Glenn R. Jones, James B.
O'Brien, Ruth E. Warren, Kevin P. Coyle, Cynthia A. Winning, Elizabeth M.
Steele, Wayne H. Davis and Larry W. Kaschinske. The following persons were
appointed as executive officers of the General Partner on April 7, 1999: Ralph
J. Roberts, Brian L. Roberts, Lawrence S. Smith, John R. Alchin and Stanley
Wang.

         Comcast is principally engaged in the development, management and
operation of broadband cable networks and in the provision of content through
programming investments. Comcast Cable is principally engaged in the
development, management and operation of broadband cable networks. The address
of Comcast's principal office is 1500 Market Street, Philadelphia, Pennsylvania
19102-2148, which is also now the address of the General Partner's principal
office. The address of Comcast Cable's principal office is 1201 Market Street,
Suite 2201, Wilmington, Delaware 19801.

(2)     On January 29, 1999, the Partnership sold the Littlerock System to a
subsidiary of the General Partner for $10,720,400, subject to customary closing
adjustments. The sale was approved by the holders of a majority of the limited
partnership interests of the Partnership. Upon the closing of the sale of the
Littlerock System, the Partnership retained $1,000,000 of the sale proceeds for
a reserve for expenses that the Partnership may incur related to then-pending
litigation, repaid all of its indebtedness (including $380,466 in advances from
the General Partner and capital lease obligations of 

                                       6
<PAGE>
 
$25,981) and then distributed the net sale proceeds of $9,985,361 to the
Partnership's limited partners of record as of January 29, 1999. This
distribution was made in February 1999. Such distribution represented
approximately $38 for each $500 limited partnership interest, or $76 for each
$1,000 invested in the Partnership. Because the distributions to the limited
partners from the sales of the Broward System, the Surfside System and the
Littlerock System did not return 125 percent of the capital initially
contributed by the limited partners to the Partnership, the General Partner did
not receive a general partner distribution from the Littlerock System's sale
proceeds.

         Taking into account the distributions from prior system sales and the
distribution from the sale of the Littlerock System, the limited partners of the
Partnership have received a total of $432 for each $500 limited partnership
interest, or $864 for each $1,000 invested in the Partnership.

         In January 1999, City Partnership Co. ("Plaintiff"), a limited partner
of the Partnership, filed a class action complaint in the District Court,
Arapahoe County, State of Colorado (Case No. 99-CV-0150) naming the General
Partner as defendant. Plaintiff, on its behalf and on behalf of all other
persons who are limited partners of the Partnership, challenged the terms of the
sale of the Littlerock System to an affiliate of the General Partner. The
General Partner filed a motion to dismiss the class action complaint on the
grounds that the plaintiff could only bring the action derivatively and not as a
class action. The court granted the Company's motion to dismiss in April 1999.
There can be no assurance, however, that the plaintiff will not refile its
complaint as a derivative action.

         Although the sale of the Littlerock System represented the sale of the
only remaining cable television system of the Partnership, the Partnership will
not be dissolved until after the recently dismissed litigation challenging the
Partnership's January 1999 sale of its Littlerock System to an affiliate of the
General Partner is finally resolved and terminated.

(3)      The General Partner manages 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 and the Venture for the
three month periods ended March 31, 1999 and 1998 were $11,854 and $526,804,
respectively. The General Partner has not received and will not receive a
management fee after January 29, 1999.

         The Partnership will continue to reimburse the 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. Reimbursements made to the General Partner by
the Partnership and the Venture for overhead and administrative expenses for the
three month periods ended March 31, 1999 and 1998 were $14,774 and $609,192,
respectively.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                            RESULTS OF OPERATIONS 


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

         The Partnership owned the Littlerock System until its sale on January
29, 1999 and the Surfside System until its sale on June 30, 1998. The
Partnership also owned a 73 percent interest in the Venture until its
liquidation and dissolution in October 1998. The accompanying financial
statements historically include 100 percent of the accounts of the Partnership
and those of the Venture, reduced by the 27 percent minority interest in the
Venture owned by Fund 14-A.

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

           Due to the Littlerock System sale on January 29, 1999, which was the
Partnership's last remaining operating asset, a full discussion of the results
of operations would not be meaningful. For the period ended March 31, 1999, the
Partnership had total revenues of $237,069 and generated operating income of
$19,245. Other expenses of $487,906 and $587,846 incurred in the first quarter
of 1999 and 1998, respectively, related to various costs associated with the
sales of the Partnership's and Venture's systems. Because of the gain of

income of $5,015,943, or $19.18 per limited partnership unit, for the three
months ended March 31, 1999.

                          PART II - OTHER INFORMATION




Item 1.  Legal Proceedings

                  In January 1999, City Partnership Co. ("Plaintiff"), a limited
         partner of the Partnership, filed a class action complaint in the
         District Court, Arapahoe County, State of Colorado (Case No. 99-CV-
         0150) naming the General Partner as defendant. Plaintiff, on its behalf
         and on behalf of all other persons who are limited partners of the
         Partnership, challenged the terms of the sale of the Littlerock System
         to an affiliate of the General Partner. The General Partner filed a
         motion to dismiss the class action complaint on the grounds that the
         plaintiff could only bring the action derivatively and not as a class
         action. The court granted the Company's motion to dismiss in April
         1999. There can be no assurance, however, that the plaintiff will not
         refile its complaint as a derivative action.
