wherever such third-party notices normally appear. The contents | |||
of the NOTICE file are for informational purposes only and | |||
do not modify the License. You may add Your own attribution | |||
notices within Derivative Works that You distribute, alongside | |||
or as an addendum to the NOTICE text from the Work, provided | |||
that such additional attribution notices cannot be construed | |||
as modifying the License. | |||
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 | |||

risks associated with Your exercise of permissions under this License. | |||
8. Limitation of Liability. In no event and under no legal theory, | |||
whether in tort (including negligence), contract, or otherwise, | |||
unless required by applicable law (such as deliberate and grossly | |||
negligent acts) or agreed to in writing, shall any Contributor be | |||
