88 | | - as of the date such litigation is filed. |

116 | | - wherever such third-party notices normally appear. The contents |
117 | | - of the NOTICE file are for informational purposes only and |

119 | | - notices within Derivative Works that You distribute, alongside |
120 | | - or as an addendum to the NOTICE text from the Work, provided |
121 | | - that such additional attribution notices cannot be construed |

123 | | - |
124 | | - You may add Your own copyright statement to Your modifications and |
125 | | - may provide additional or different license terms and conditions |
126 | | - for use, reproduction, or distribution of Your modifications, or |
127 | | - for any such Derivative Works as a whole, provided Your use, |
128 | | - reproduction, and distribution of the Work otherwise complies with |
129 | | - the conditions stated in this License. |
130 | | - |
131 | | - 5. Submission of Contributions. Unless You explicitly state otherwise, |
132 | | - any Contribution intentionally submitted for inclusion in the Work |
133 | | - by You to the Licensor shall be under the terms and conditions of |
134 | | - this License, without any additional terms or conditions. |
135 | | - Notwithstanding the above, nothing herein shall supersede or modify |
136 | | - the terms of any separate license agreement you may have executed |
137 | | - with Licensor regarding such Contributions. |
138 | | - |
139 | | - 6. Trademarks. This License does not grant permission to use the trade |
140 | | - names, trademarks, service marks, or product names of the Licensor, |
141 | | - except as required for reasonable and customary use in describing the |
142 | | - origin of the Work and reproducing the content of the NOTICE file. |
143 | | - |
144 | | - 7. Disclaimer of Warranty. Unless required by applicable law or |
145 | | - agreed to in writing, Licensor provides the Work (and each |
146 | | - Contributor provides its Contributions) on an "AS IS" BASIS, |
147 | | - WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or |
148 | | - implied, including, without limitation, any warranties or conditions |
149 | | - of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A |

153 | | - |
154 | | - 8. Limitation of Liability. In no event and under no legal theory, |
155 | | - whether in tort (including negligence), contract, or otherwise, |
156 | | - unless required by applicable law (such as deliberate and grossly |
157 | | - negligent acts) or agreed to in writing, shall any Contributor be |
158 | | - liable to You for damages, including any direct, indirect, special, |
159 | | - incidental, or consequential damages of any character arising as a |
160 | | - result of this License or out of the use or inability to use the |
161 | | - Work (including but not limited to damages for loss of goodwill, |
162 | | - work stoppage, computer failure or malfunction, or any and all |
163 | | - other commercial damages or losses), even if such Contributor |
164 | | - has been advised of the possibility of such damages. |
165 | | - |
166 | | - 9. Accepting Warranty or Additional Liability. While redistributing |
167 | | - the Work or Derivative Works thereof, You may choose to offer, |
168 | | - and charge a fee for, acceptance of support, warranty, indemnity, |
169 | | - or other liability obligations and/or rights consistent with this |
170 | | - License. However, in accepting such obligations, You may act only |
171 | | - on Your own behalf and on Your sole responsibility, not on behalf |
172 | | - of any other Contributor, and only if You agree to indemnify, |
173 | | - defend, and hold each Contributor harmless for any liability |
174 | | - incurred by, or claims asserted against, such Contributor by reason |
175 | | - of your accepting any such warranty or additional liability. |
