        g.   Notwithstanding the foregoing, no Commission will be paid to
Representative in connection with the sale of any Service:

             1.   to Representative, Representative's employees or any
other NYNEX representative(s) including Affiliates, subsidiaries, parent

             4.   for which an order, still pending, was previously

             6.   for any order that has been sold by a party, or
subcontractor other than Representative unless otherwise approved by NYNEX;

             7.   for any order that merely moves the same Service from

prior written concurrence from NYNEX;

             10.  for any order not completed or Service not installed
for any reason.

AMP Program NYNEX agrees to pay Representative as set forth in Appendix B.
hereto.

sales program.

employees shall not make an employee of the Representative's an employee of

be reported by Representative against the sales person responsible for the
sale.

   4.   Set Off
