"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the

the Work and Derivative Works thereof.

"Contribution" shall mean any work of authorship, including the original
version of the Work and any modifications or additions to that Work or

For the purposes of this definition, "submitted" means any form of
electronic, verbal, or written communication sent to the Licensor
or its representatives, including but not limited to communication

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 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.
