Agreement, which limits the amount of Management Fees payable by the Company,
all in the manner described herein. The Company has further requested that the

         in the ordinary course of the businesses of the Company, and in good
         faith and upon commercially reasonable terms that are no less

         distributions to the Partners as shall be necessary to cover each such

         not to exceed Jones' Weighted Average Cost of Borrowing for the period

         Default or Default hereunder, the Company may pay, prior to March 31,
         1996, accrued interest on deferred Management Fees and Home Office
         Allocations at a rate not to exceed Jones, Weighted Average Cost of
         Borrowing for the period during which the payment of such Management

         that after March 31, 1996, the Company may accrue and defer (but not
         pay until

         of a System, and for the sale of television or other signals, the
         purchase or lease of television or other signals or specialized
         equipment and the licensing of technology, provided (x) such

         place by unrelated parties for goods or services as nearly identical
         as possible in regard to quality, technical advancement and
         availability, provided, however, that so long as no Default or Event
         of Default is in existence, the Company may pay brokerage fees to The
         Jones Group, Ltd. in connection with (a) the sale of a System to an
         entity which is not an Affiliate in an amount not to exceed two and
         one-half percent (2-1/2%) of the gross sales price of the System, and
