various appliances and equipment including but not limited to, an on-site waste

         WHEREAS, Supplier and Distributor have agreed that Supplier will grant
to Distributor, and Distributor will accept, the rights to market and sell the

successive five-year periods (the initial term and each such successive term
being referred to herein as a "Contract Period"), unless Distributor, in its
sole discretion, reduces the term of this Agreement to the then current Contract

for the Products and acknowledges that the rights granted hereunder constitute a
non-assignable, non-licensable privilege to use such Trade Designations only in
a limited manner and in connection with the distribution, marketing,
advertising, display and sale of the Products during the Contract Period and
such additional period during which Distributor is permitted to sell the

            (b) Infringement of Proprietary Rights by Others. During the term of

Supplier of an infringement by a third party of any of the Proprietary Rights of
which Distributor actually becomes aware, and may request that Supplier proceed
to take steps to end such infringement as soon as possible. If Supplier wishes
to pursue such action, it will so notify Distributor within thirty (30) days of
learning of the possible infringement. The expenses of such suit, including
legal fees, shall be paid by Supplier. If Supplier elects not to pursue such
action, or if Distributor does not receive such notice, Distributor shall have

         (c) Defense of Infringement Claims. Supplier will defend at its own
expense any suits or claims instituted against Distributor by any third person
claiming that the manufacture, sale, distribution or use of the Products
constitutes an infringement of patent rights or other intellectual property
rights held by such third person, upon notice thereof from Distributor.
Distributor may appoint its own legal counsel to represent its interest in said
suit at its own expense, but such appointment shall not diminish the obligations
of Supplier. In addition, Supplier will defend, indemnify and hold harmless
Distributor and its officers and agents, from and against all liability of any
kind, including damages, costs and expenses (including reasonable attorneys'
fees and accountants' fees) incurred with respect to claims made by any third
party based on any alleged infringement of patent rights or other proprietary
rights of said third parties claimed to result or arise from the manufacture,
sale, distribution or use of the Products.

venture or partnership.

License Rider by and between Supplier and Distributor, and nothing herein
contained is intended, nor shall it be deemed or interpreted, to amend, modify
