+publicly display, publicly perform, sublicense, and distribute the Work and such

+their Contribution(s) with the Work to which such Contribution(s) was submitted.
+If You 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
+as of the date such litigation is filed.
+

+
+You may reproduce and distribute copies of the Work or Derivative Works thereof

+provided that You meet the following conditions:
+

+    this License; and
+
+(b) You must cause any modified files to carry prominent notices stating that You
+    changed the files; and
+
+(c) You must retain, in the Source form of any Derivative Works that You
+    distribute, all copyright, patent, trademark, and 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 pertain to any part of the Derivative Works, in at least
+    one 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 the terms of
+any separate license agreement you may have executed with Licensor regarding such
+Contributions.
+
+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.
