2. Grant of Copyright License. Subject to the terms and conditions of this

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 hereby grants to You a perpetual, worldwide,

non-exclusive, no-charge, royalty-free, irrevocable (except as stated in

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 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

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.
