+   within a display generated by the Derivative Works, if and
+   wherever such third-party notices normally appear. The contents
+   of the NOTICE file are for informational purposes only and

+   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

+   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,

+    (except as stated in this section) patent license to make, have made,

+    within a display generated by the Derivative Works, if and
+    wherever such third-party notices normally appear. The contents
+    of the NOTICE file are for informational purposes only and
