   by Sections 1 through 9 of this document.

   "Licensor" shall mean the copyright owner or entity authorized by the copyright owner that is
   granting the License.

   "Legal Entity" shall mean the union of the acting entity and all other entities that control, are

   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 of, the Licensor for the purpose of discussing and improving the Work, but 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.

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.
