percent (50%) or more of the outstanding shares, or (iii) beneficial ownership
of such entity.

"You" (or "Your") shall mean an individual or Legal Entity
exercising permissions granted by this License.

"Source" form shall mean the preferred form for making modifications,
including but not limited to software source code, documentation source, and
configuration files.

"Object" form shall mean any form resulting from mechanical
transformation or translation of a Source form, including but not limited to
compiled object code, generated documentation, and conversions to other media
types.

"Work" shall mean the work of authorship, whether in Source or Object
form, made available under the License, as indicated by a copyright notice that
is included in or attached to the work (an example is provided in the Appendix
below).

"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 editorial
revisions, annotations, elaborations, or other modifications represent, as a
whole, an original work of authorship. For the purposes 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 to Licensor for
inclusion in the Work by the copyright owner or by an individual or Legal
Entity authorized to submit on behalf of the copyright owner. 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 on electronic mailing lists, source code
control systems, and issue tracking systems that are managed by, or on behalf

excluding communication that is conspicuously marked or otherwise designated in
writing by the copyright owner as "Not a Contribution."

"Contributor" shall mean Licensor and any individual or Legal Entity
on behalf of whom a Contribution has been received by Licensor and subsequently
incorporated within the Work.

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. Any
patent license granted hereby with respect to contributions by an individual
employed by an institution or organization is limited to patent claims where
the individual that is the author of the Work is also the inventor of the
patent claims licensed, and where the organization or institution has the right
to grant such license under applicable grant and research funding agreements.
No other express or implied licenses are granted.

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.
