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

of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of,
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 Derivative Works thereof, that is intentionally submitted

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:

   (a) You must give any other recipients of the Work or Derivative Works
   a copy of this License; and

   (b) You must cause any modified files to carry prominent notices stating
   that You changed the files; and

   (c) 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

   (d) 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.
