 63 | Subject to the terms and conditions of this License, each Contributor hereby
 64 | grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
 65 | irrevocable copyright license to reproduce, prepare Derivative Works of,

 79 | cross-claim or counterclaim in a lawsuit) alleging that the Work or a
 80 | Contribution incorporated within the Work constitutes direct or contributory
 81 | patent infringement, then any patent licenses granted to You under this License
 82 | for that Work shall terminate as of the date such litigation is filed.
 83 | 
 84 | 4. Redistribution.
 85 | 
 86 | You may reproduce and distribute copies of the Work or Derivative Works thereof
 87 | in any medium, with or without modifications, and in Source or Object form,
 88 | provided that You meet the following conditions:
 89 | 
 90 | You must give any other recipients of the Work or Derivative Works a copy of
 91 | this License; and
 92 | You must cause any modified files to carry prominent notices stating that You
 93 | changed the files; and
 94 | You must retain, in the Source form of any Derivative Works that You distribute,
 95 | all copyright, patent, trademark, and attribution notices from the Source form

101 | that do not pertain to any part of the Derivative Works, in at least one of the
102 | following places: within a NOTICE text file distributed as part of the
103 | Derivative Works; within the Source form or documentation, if provided along
104 | with the Derivative Works; or, within a display generated by the Derivative
105 | Works, if and wherever such third-party notices normally appear. The contents of
106 | the NOTICE file are for informational purposes only and do not modify the
107 | License. You may add Your own attribution notices within Derivative Works that
108 | You distribute, alongside or as an addendum to the NOTICE text from the Work,
109 | provided that such additional attribution notices cannot be construed as
110 | modifying the License.
111 | You may add Your own copyright statement to Your modifications and may provide
112 | additional or different license terms and conditions for use, reproduction, or
113 | distribution of Your modifications, or for any such Derivative Works as a whole,
114 | provided Your use, reproduction, and distribution of the Work otherwise complies

124 | such Contributions.
125 | 
126 | 6. Trademarks.
127 | 
128 | This License does not grant permission to use the trade names, trademarks,
129 | service marks, or product names of the Licensor, except as required for
130 | reasonable and customary use in describing the origin of the Work and
131 | reproducing the content of the NOTICE file.
132 | 
133 | 7. Disclaimer of Warranty.
134 | 
135 | Unless required by applicable law or agreed to in writing, Licensor provides the
136 | Work (and each Contributor provides its Contributions) on an "AS IS" BASIS,
137 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
138 | including, without limitation, any warranties or conditions of TITLE,
139 | NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
140 | solely responsible for determining the appropriateness of using or
141 | redistributing the Work and assume any risks associated with Your exercise of
142 | permissions under this License.
143 | 
144 | 8. Limitation of Liability.

148 | and grossly negligent acts) or agreed to in writing, shall any Contributor be
149 | liable to You for damages, including any direct, indirect, special, incidental,
150 | or consequential damages of any character arising as a result of this License or
151 | out of the use or inability to use the Work (including but not limited to
152 | damages for loss of goodwill, work stoppage, computer failure or malfunction, or
153 | any and all other commercial damages or losses), even if such Contributor has
154 | been advised of the possibility of such damages.
155 | 
156 | 9. Accepting Warranty or Additional Liability.
157 | 
158 | While redistributing the Work or Derivative Works thereof, You may choose to
159 | offer, and charge a fee for, acceptance of support, warranty, indemnity, or
160 | other liability obligations and/or rights consistent with this License. However,
161 | in accepting such obligations, You may act only on Your own behalf and on Your
162 | sole responsibility, not on behalf of any other Contributor, and only if You
163 | agree to indemnify, defend, and hold each Contributor harmless for any liability
164 | incurred by, or claims asserted against, such Contributor by reason of your
165 | accepting any such warranty or additional liability.
166 | 
167 | END OF TERMS AND CONDITIONS
