113 | of the following places: within a NOTICE text file distributed
114 | as part of the Derivative Works; within the Source form or
115 | documentation, if provided along with the Derivative Works; or,
116 | within a display generated by the Derivative Works, if and
117 | wherever such third-party notices normally appear. The contents
118 | of the NOTICE file are for informational purposes only and
119 | do not modify the License. You may add Your own attribution
120 | notices within Derivative Works that You distribute, alongside
121 | or as an addendum to the NOTICE text from the Work, provided
122 | that such additional attribution notices cannot be construed
123 | as modifying the License.
124 |
125 | You may add Your own copyright statement to Your modifications and

130 | the conditions stated in this License.
131 |
132 | 5. Submission of Contributions. Unless You explicitly state otherwise,
133 | any Contribution intentionally submitted for inclusion in the Work
134 | by You to the Licensor shall be under the terms and conditions of
135 | this License, without any additional terms or conditions.
136 | Notwithstanding the above, nothing herein shall supersede or modify
137 | the terms of any separate license agreement you may have executed
138 | with Licensor regarding such Contributions.
139 |
140 | 6. Trademarks. This License does not grant permission to use the trade
141 | names, trademarks, service marks, or product names of the Licensor,
142 | except as required for reasonable and customary use in describing the
143 | origin of the Work and reproducing the content of the NOTICE file.
144 |
145 | 7. Disclaimer of Warranty. Unless required by applicable law or
146 | agreed to in writing, Licensor provides the Work (and each
147 | Contributor provides its Contributions) on an "AS IS" BASIS,
148 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
149 | implied, including, without limitation, any warranties or conditions
150 | of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
151 | PARTICULAR PURPOSE. You are solely responsible for determining the
152 | appropriateness of using or redistributing the Work and assume any
153 | risks associated with Your exercise of permissions under this License.
154 |

156 | whether in tort (including negligence), contract, or otherwise,
157 | unless required by applicable law (such as deliberate and grossly
158 | negligent acts) or agreed to in writing, shall any Contributor be
159 | liable to You for damages, including any direct, indirect, special,
160 | incidental, or consequential damages of any character arising as a
161 | result of this License or out of the use or inability to use the
162 | Work (including but not limited to damages for loss of goodwill,
163 | work stoppage, computer failure or malfunction, or any and all
164 | other commercial damages or losses), even if such Contributor
165 | has been advised of the possibility of such damages.
166 |
167 | 9. Accepting Warranty or Additional Liability. While redistributing
168 | the Work or Derivative Works thereof, You may choose to offer,
169 | and charge a fee for, acceptance of support, warranty, indemnity,
170 | or other liability obligations and/or rights consistent with this
171 | License. However, in accepting such obligations, You may act only
172 | on Your own behalf and on Your sole responsibility, not on behalf
173 | of any other Contributor, and only if You agree to indemnify,
174 | defend, and hold each Contributor harmless for any liability
175 | incurred by, or claims asserted against, such Contributor by reason
176 | of your accepting any such warranty or additional liability.
