"Contract"). Both parties have agreed with the execution of this amendment to
modify, amend and clarify the original Contract to grant AmeriTech, its
successors, assigns and/or any subsidiary it owns or may own, a non-exclusive,
worldwide, perpetual, royalty free license and the right to use any and all
technology (the "Technology") developed under the Contract. North American
agrees to provide training to AmeriTech and/or its assigns to use the
technology in the field as may be required by Ameritech and/or its assigns.
The Technology was developed by North American who by this amendment and the
original Contract retains the ownership to the Technology and the rights to
continue developing said Technology. North American agrees to grant AmeriTech
and/or its assigns the right to use any and all future developments to the
Technology in exchange for payments North American deems necessary, if any,
for such development. Any charges billed by North American will be reasonable
and customary for the time and expenses required for such development.
North American further agrees to process any and all data AmeriTech and/or its
assigns may gather while using the Technology for a reasonable fee that in no
case will exceed fees charged by North American for the same or similar work
to its other customers. In addition, North American agrees that should it
cease processing the data for any reason or sell either the Technology,
company or the rights to the Technology, whether by merger or license to
another party or any other form of sale, it will provide any and all software
necessary to process the data to AmeriTech and/or its assigns along with the
documentation and techniques required for AmeriTech and/or its assigns to
process the data themselves.
