* The Software will communicate with this local license server to validate the license Term and the number of active, concurrent seats.

* Bypass or breach any security device or protection used by the Software or the license server.
* Rent, lease, lend, sell, sublicense, assign, distribute, publish, transfer, or otherwise make available the Software to any third party for any reason.
* Use the Software in excess of the number of licenses purchased or outside the permitted Term.
