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,

"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 Copyright License.

Subject to the terms and conditions of this License, each Contributor hereby

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:

 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

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.
