+  where such license applies only to those patent claims licensable
+  by such Contributor that are necessarily infringed by their
+  Contribution(s) alone or by combination of their Contribution(s)
+  with the Work to which such Contribution(s) was submitted. If You
+  institute patent litigation against any entity (including a

+  or contributory patent infringement, then any patent licenses
+  granted to You under this License for that Work shall terminate
+  as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+  Work or Derivative Works thereof in any medium, with or without
+  modifications, and in Source or Object form, provided that You
+  meet the following conditions:
+
+  (a) You must give any other recipients of the Work or
+      Derivative Works a copy of this License; and
+
+  (b) You must cause any modified files to carry prominent notices

+      attribution notices from the Source form of the Work,
+      excluding those notices that do not pertain to any part of
+      the Derivative Works; and
+
+  (d) If the Work includes a "NOTICE" text file as part of its
+      distribution, then any Derivative Works that You distribute must
+      include a readable copy of the attribution notices contained
+      within such NOTICE file, excluding those notices that do not

+      of the following places: within a NOTICE text file distributed
+      as part of the Derivative Works; within the Source form or
+      documentation, if provided along with the Derivative Works; or,
+      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
+      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
+  for any such Derivative Works as a whole, provided Your use,
+  reproduction, and distribution of the Work otherwise complies with
+  the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+  any Contribution intentionally submitted for inclusion in the Work
+  by You to the Licensor shall be under the terms and conditions of
+  this License, without any additional terms or conditions.
+  Notwithstanding the above, nothing herein shall supersede or modify

+6. Trademarks. This License does not grant permission to use the trade
+  names, trademarks, service marks, or product names of the Licensor,
+  except as required for reasonable and customary use in describing the
+  origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+  agreed to in writing, Licensor provides the Work (and each
+  Contributor provides its Contributions) on an "AS IS" BASIS,
+  WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+  implied, including, without limitation, any warranties or conditions
+  of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+  PARTICULAR PURPOSE. You are solely responsible for determining the
+  appropriateness of using or redistributing the Work and assume any
+  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,
+  incidental, or consequential damages of any character arising as a
+  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
+  other commercial damages or losses), even if such Contributor
+  has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+  the Work or Derivative Works thereof, You may choose to offer,
+  and charge a fee for, acceptance of support, warranty, indemnity,
+  or other liability obligations and/or rights consistent with this
+  License. However, in accepting such obligations, You may act only
+  on Your own behalf and on Your sole responsibility, not on behalf
+  of any other Contributor, and only if You agree to indemnify,
+  defend, and hold each Contributor harmless for any liability
+  incurred by, or claims asserted against, such Contributor by reason
+  of your accepting any such warranty or additional liability.
