                          extinguished or discharged Borrower's indebtedness
                          under the Prior Notes, all of which indebtedness and

                          and be governed by the Second Amended and Restated

                          its maximum permitted basic service rate. As of the
                          Effective Date, Borrower is not aware of any refund
                          liability relating to its cost of service showing

               Fees) or other payments (including Home Office Allocations) to
               Affiliates, except, in the absence of an Event of Default or
               Default hereunder and so long as such payment shall not cause an
               Event of Default or Default hereunder: (i) in connection with
               the sale of a System as permitted by Paragraph 6.07 hereof,
               Borrower may make such distributions to the Partners as shall be
               necessary to cover each such Partner's tax liability arising in
               connection with such sale; (ii) if Borrower represents to Banks
               as of the date of any such proposed payment that it is not aware

               for any fiscal quarter of Borrower does not exceed five percent
               (5%) of Borrower's Gross Operating Revenues for such quarter and
               (2) Home Office Allocations; provided, however, that if in any
               fiscal quarter Borrower shall have repaid advances or made
               payments of Management Fees and Home Office Allocations to Jones
               at a time when such payment was permitted hereunder, but an
               Event of Default, Default or Refund Liability shall exist as of
               the end of the fiscal quarter in which such payment(s) were
               made, Jones shall repay the same to Borrower immediately upon

               Borrower's Operating Cash Flow for such quarter may, prior to
               March 31, 1996, be deferred and subordinated to the Loan
               pursuant to the Subordination Agreement; provided, further, that
               so long as there exists no Event of Default or Default under
               this Agreement or Refund Liability, and the making of such
               payment does not cause an Event of Default or Default hereunder,
               Borrower may pay, prior to March 31, 1996, accrued interest on
               deferred Management Fees and Home Office Allocations at a rate
               not to exceed Jones' average cost of funds; and provided
               further, that after March 31, 1996, Borrower may accrue and
               defer (but may not pay until the Loan has been paid in full)
               (x) Management fees in the amounts described in Subparagraph
               6.09 (ii)(B)(1) above and (y) Home Office Allocations; and (iii)

               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, Borrower 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
