4. You may not copy, modify, sublicense, or distribute the
Program except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense or distribute the
Program is void, and will automatically terminate your rights
under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify
or distribute the Program or its derivative works. These actions
are prohibited by law if you do not accept this License. Therefore,
by modifying or distributing the Program (or any work based on
the Program), you indicate your acceptance of this License to do
so, and all its terms and conditions for copying, distributing or
modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on
the Program), the recipient automatically receives a license from
the original licensor to copy, distribute or modify the Program
subject to these terms and conditions. You may not impose any
further restrictions on the recipients' exercise of the rights gran-
ted herein. You are not responsible for enforcing compliance by
third parties to this License.
7. If, as a consequence of a court judgment or allegation of
patent infringement or for any other reason (not limited to
patent issues), conditions are imposed on you (whether by court
order, agreement or otherwise) that contradict the conditions of
this License, they do not excuse you from the conditions of this
License.
