institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate

that such additional attribution notices cannot be construed

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or

reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all

or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
