  88. the NOTICE file are for informational purposes only and do not modify the
  89. License. You may add Your own attribution notices within Derivative Works that
  90. You distribute, alongside or as an addendum to the NOTICE text from the Work,

  104. such Contributions.
  105. #### 6. Trademarks
  106. This License does not grant permission to use the trade names, trademarks,
  107. service marks, or product names of the Licensor, except as required for
  108. reasonable and customary use in describing the origin of the Work and
  109. reproducing the content of the NOTICE file.
  110. #### 7. Disclaimer of Warranty
  111. Unless required by applicable law or agreed to in writing, Licensor provides the
  112. Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
  113. WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
  114. including, without limitation, any warranties or conditions of TITLE,
  115. NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
  116. solely responsible for determining the appropriateness of using or
  117. redistributing the Work and assume any risks associated with Your exercise of
  118. permissions under this License.
  119. #### 8. Limitation of Liability
  120. In no event and under no legal theory, whether in tort (including negligence),

  124. or consequential damages of any character arising as a result of this License or
  125. out of the use or inability to use the Work (including but not limited to

  127. any and all other commercial damages or losses), even if such Contributor has
  128. been advised of the possibility of such damages.
  129. #### 9. Accepting Warranty or Additional Liability
  130. While redistributing the Work or Derivative Works thereof, You may choose to
  131. offer, and charge a fee for, acceptance of support, warranty, indemnity, or
  132. other liability obligations and/or rights consistent with this License. However,
  133. in accepting such obligations, You may act only on Your own behalf and on Your
  134. sole responsibility, not on behalf of any other Contributor, and only if You
  135. agree to indemnify, defend, and hold each Contributor harmless for any liability
  136. incurred by, or claims asserted against, such Contributor by reason of your
  137. accepting any such warranty or additional liability.
  138. _END OF TERMS AND CONDITIONS_
