 94  licensable by such Contributor that are necessarily infringed by their Contribution(s)
 95  alone or by combination of their Contribution(s) with the Work to which such
 96  Contribution(s) was submitted. If You institute patent litigation against
 97  any entity (including a cross-claim or counterclaim in a lawsuit) alleging
 98  that the Work or a Contribution incorporated within the Work constitutes direct
 99  or contributory patent infringement, then any patent licenses granted to You
100  under this License for that Work shall terminate as of the date such litigation
101  is filed.
102  
103  4. Redistribution. You may reproduce and distribute copies of the Work or
104  Derivative Works thereof in any medium, with or without modifications, and
105  in Source or Object form, provided that You meet the following conditions:
106  
107  (a) You must give any other recipients of the Work or Derivative Works a copy
108  of this License; and
109  
110  (b) You must cause any modified files to carry prominent notices stating that
111  You changed the files; and
112  
113  (c) You must retain, in the Source form of any Derivative Works that You distribute,
114  all copyright, patent, trademark, and attribution notices from the Source
115  form of the Work, excluding those notices that do not pertain to any part
116  of the Derivative Works; and
117  
118  (d) If the Work includes a "NOTICE" text file as part of its distribution,
119  then any Derivative Works that You distribute must include a readable copy
120  of the attribution notices contained within such NOTICE file, excluding those
121  notices that do not pertain to any part of the Derivative Works, in at least
122  one of the following places: within a NOTICE text file distributed as part
123  of the Derivative Works; within the Source form or documentation, if provided
124  along with the Derivative Works; or, within a display generated by the Derivative
125  Works, if and wherever such third-party notices normally appear. The contents
126  of the NOTICE file are for informational purposes only and do not modify the
127  License. You may add Your own attribution notices within Derivative Works
128  that You distribute, alongside or as an addendum to the NOTICE text from the
129  Work, provided that such additional attribution notices cannot be construed
130  as modifying the License.
131  
132  You may add Your own copyright statement to Your modifications and may provide
133  additional or different license terms and conditions for use, reproduction,
134  or distribution of Your modifications, or for any such Derivative Works as
135  a whole, provided Your use, reproduction, and distribution of the Work otherwise
136  complies with the conditions stated in this License.
137  
138  5. Submission of Contributions. Unless You explicitly state otherwise, any
139  Contribution intentionally submitted for inclusion in the Work by You to the
140  Licensor shall be under the terms and conditions of this License, without
141  any additional terms or conditions. Notwithstanding the above, nothing herein
142  shall supersede or modify the terms of any separate license agreement you
143  may have executed with Licensor regarding such Contributions.
144  
145  6. Trademarks. This License does not grant permission to use the trade names,
146  trademarks, service marks, or product names of the Licensor, except as required
147  for reasonable and customary use in describing the origin of the Work and
148  reproducing the content of the NOTICE file.
149  
150  7. Disclaimer of Warranty. Unless required by applicable law or agreed to
151  in writing, Licensor provides the Work (and each Contributor provides its
152  Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
153  KIND, either express or implied, including, without limitation, any warranties
154  or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR
155  A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness
156  of using or redistributing the Work and assume any risks associated with Your
157  exercise of permissions under this License.
158  
159  8. Limitation of Liability. In no event and under no legal theory, whether
160  in tort (including negligence), contract, or otherwise, unless required by
161  applicable law (such as deliberate and grossly negligent acts) or agreed to
162  in writing, shall any Contributor be liable to You for damages, including
163  any direct, indirect, special, incidental, or consequential damages of any
164  character arising as a result of this License or out of the use or inability
165  to use the Work (including but not limited to damages for loss of goodwill,
166  work stoppage, computer failure or malfunction, or any and all other commercial
167  damages or losses), even if such Contributor has been advised of the possibility
168  of such damages.
169  
170  9. Accepting Warranty or Additional Liability. While redistributing the Work
171  or Derivative Works thereof, You may choose to offer, and charge a fee for,
172  acceptance of support, warranty, indemnity, or other liability obligations
173  and/or rights consistent with this License. However, in accepting such obligations,
174  You may act only on Your own behalf and on Your sole responsibility, not on
175  behalf of any other Contributor, and only if You agree to indemnify, defend,
176  and hold each Contributor harmless for any liability incurred by, or claims
177  asserted against, such Contributor by reason of your accepting any such warranty
178  or additional liability. END OF TERMS AND CONDITIONS
