+                        publicly display, publicly perform, sublicense, and distribute the Work and such

+                        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

+                        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.

+                        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

+                        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

+                        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.

+                    <p>
+
+                        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.

+                    <p>
+                        7. Disclaimer of Warranty.
+
+                        Unless required by applicable law or agreed to in writing, Licensor provides the

+                        WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
+                        including, without limitation, any warranties or conditions of TITLE,

+                        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

+                        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

+                        recommend that a file or class name and description of purpose be included on
+                        the same "printed page" as the copyright notice for easier identification within
+                        third-party archives.
