"Derivative Works" shall mean any work, whether in Source or
Object form, that is based on (or derived from) the Work and

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

Entity on behalf of whom a Contribution has been received by

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

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.
