+  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
+  liable to You for damages, including any direct, indirect, special,
