no-charge, royalty-free, irrevocable license under the Rights to reproduce,
prepare Derivative Works of, publicly display, publicly perform, sublicense,
and distribute the Work and such Derivative Works in Source or Object form
and do anything in relation to the Work as if the Rights did not exist.

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.

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

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. END OF TERMS AND CONDITIONS
