        d.   It is NYNEX's intent to pay commissions not later than
thirty (30) days following the end of the month during which a fully

schedule in effect at the time NYNEX acknowledges an accurate and fully
negotiated order submitted by Representative.  However, where as a result of
customer action an order is postponed beyond six (6) months from the Order
Issuance Date, the Commission in effect when the customer reorders the Service

Representative in connection with the sale of any Service:

             1.   to Representative, Representative's employees or any

companies or divisions of either party unless receiving prior written
concurrence from NYNEX;

to the effective date of this Agreement;

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

             5.   for any order made in which Representative has offered

sale.

             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
one tariff to another or shifts the Service from one customer bill to another
without, at the same time, placing that Service under a longer than current
term contract period, Rate Stability Plan or Service Discount Plan;

             8.   for any order where misrepresentation or fraudulent

order was placed or the length of time the Service has been installed;

             9.   for any sale of Services outside the Designated Sales
Area, except for qualifying sales made in the Incidental Sales Area or with
prior written concurrence from NYNEX;

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

   2.   Account Management Plan (AMP) Compensation

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

        b.   Payment hereunder shall be made monthly during the term of
the AMP Program.  AMP compensation will be paid not later than thirty (30)

a moratorium on accepting for approval new AMP account plans.

        c.   Compensation hereunder with respect to any AMP account
plan(s) may be discontinued or reduced should a NYNEX review reveal a lack of

lack of performance by Representative has existed.

customer profiles, progress status reports, and proposals must be provided to
NYNEX upon request, and in any event within ten (10) business days after the
termination or expiration of this Agreement.  After such termination or

program is in effect and shall be subject to change with each new promotional
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.
