### 2. Grant of Copyright License.

Subject to the terms and conditions of this License, each Contributor
hereby grants to You a perpetual, worldwide, non-exclusive, no-charge,
royalty-free, irrevocable copyright license to reproduce, prepare
Derivative Works of, publicly display, publicly perform, sublicense,
and distribute the Work and such Derivative Works in Source or Object
form.

### 3. Grant of Patent License.

Subject to the terms and conditions of this License, each Contributor

license to make, have made, use, offer to sell, sell, import, and
otherwise transfer the Work, 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 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

   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

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

(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.
