   "Work" shall mean the work of authorship, whether in Source or Object form,

   that is included in or attached to the work (an example is provided in the

   "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

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

2. Grant of 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.

3. 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.

4. 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.

5. 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 describing the origin of the Work and
   reproducing the content of the NOTICE file.

6. 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.

7. 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.

8. 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 services.
   However, in accepting such obligations, You may act only on Your own behalf and on Your sole
   responsibility, not on behalf of any 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.

9. Miscellaneous.

   This License represents the complete agreement concerning the subject matter herein and
   supersedes all prior agreements or understandings, whether written or oral, relating to the subject
   matter of this License. If any provision of this License is held to be unenforceable, such provision
   shall be reformed only to the extent necessary to make it enforceable. Any failure to enforce any
   provision of this License shall not constitute a waiver of such provision. This License does not,
   and shall not be, construed as granting any rights to use the trademarks, service marks, or logos of
   the Licensor except as expressly stated herein.

   Each Contributor's rights under this License shall terminate automatically if You breach any of the
   terms and conditions of this License. However, this License will terminate Your rights only
   for the specific Contributions affected by such a breach.

   If You bring a claim for patent infringement 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.

   Sections 1 through 9 shall survive termination of this License.

                              END OF TERMS AND CONDITIONS
