### 2. Grant of Copyright License

irrevocable copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the Work and such

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.

### 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:

1. You must give any other recipients of the Work or Derivative Works a copy of
   this License; and

2. You must cause any modified files to carry prominent notices stating that You
   changed the files; and

3. 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

4. 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

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.
