"Derivative Works" shall mean any work, whether in Source or Object form, that

2. Grant of Copyright License.

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

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 this section) patent 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:

You must give any other recipients of the Work or Derivative Works a copy of

this License; and

You must cause any modified files to carry prominent notices stating that You

changed the files; and

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

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.
