         Re:     Third Letter Amendment to Cable TV Fund 14-A/B Venture
                 Revolving Credit and Term Loan Agreement

Gentlemen:

         Reference is made to that certain Revolving Credit and Term Loan
Agreement, dated as of September 30, 1988, by and among Cable TV Fund 14-A/B
Venture (the "Borrower"), The Bank of Nova Scotia and PNC Bank, National
Association (formerly known as Provident National Bank)  (the "Banks") and The
Bank of Nova Scotia, as agent for the Banks (the "Agent"), as amended by that
certain First Letter Amendment, dated June 11, 1990, and that certain Second
Letter Amendment, dated May 28, 1992 (the "Credit Agreement").   Capitalized
terms used herein and not otherwise defined shall have the meanings assigned to
them in the Credit Agreement.

         The Borrower desires the Banks to amend (a) the principal amortization
schedule for the Term Loans and (b) the Total Debt to Annualized Cash Flow
ratio covenant.   The Banks are willing to amend the Credit Agreement for such
purposes on the terms and conditions stated in this Third Letter Amendment.

         Effective upon the satisfaction (or waiver by the Banks) of all of the
conditions precedent stated below, the Credit Agreement shall be amended as
follows:

         1.    Paragraph A of Section 2.6 is hereby deleted in its entirety and
               replaced with the following language:

                 "(A) On each March 31, June 30, September 30 and December 31
         during each period indicated below the Term Loan Ceiling shall be
         reduced by amounts equal to the





                                      -1-
   2
         following percentages of the Initial Ceiling (regardless of whether
         the Term Loan Ceiling shall have been reduced pursuant to (B) or (C)
         below):


                                                                 
                 January 1, 1993 - December 31, 1993                1.875%
                 January 1, 1994 - March 31, 1994                       0%
                 April 1, 1994   - December 31, 1994                0.833%
                 January 1, 1995 - December 31, 1995                1.250%
                 January 1, 1996 - December 31, 1996                1.875%
                 January 1, 1997 - September 30, 1999               2.500%


         On December 31, 1999 the Term Loan Ceiling shall be reduced to zero
(0)."

         2.    Section 6.1(a) is amended by deleting the last two lines of the
table of ratios of Total Debt to Annualized Cash Flow and replacing them with
the following:


                                                
         "January 1, 1994 - March 31, 1995         5.00 to 1.00
         April 1, 1995 - March 31, 1996            4.50 to 1.00
         April 1, 1996 - March 31, 1997            4.00 to 1.00
         April 1, 1997 - December 31, 1999         3.50 to 1.00"
