 99 |           stating that You changed the files; and
100 | 
101 |       (c) You must retain, in the Source form of any Derivative Works
102 |           that You distribute, all copyright, patent, trademark, and
103 |           attribution notices from the Source form of the Work,
104 |           excluding those notices that do not pertain to any part of
105 |           the Derivative Works; and
106 | 
107 |       (d) If the Work includes a "NOTICE" text file as part of its
108 |           distribution, then any Derivative Works that You distribute must
109 |           include a readable copy of the attribution notices contained
110 |           within such NOTICE file, excluding those notices that do not
111 |           pertain to any part of the Derivative Works, in at least one
112 |           of the following places: within a NOTICE text file distributed
113 |           as part of the Derivative Works; within the Source form or
114 |           documentation, if provided along with the Derivative Works; or,
115 |           within a display generated by the Derivative Works, if and
116 |           wherever such third-party notices normally appear. The contents
117 |           of the NOTICE file are for informational purposes only and
118 |           do not modify the License. You may add Your own attribution
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
122 |           as modifying the License.
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
150 |       PARTICULAR PURPOSE. You are solely responsible for determining the
151 |       appropriateness of using or redistributing the Work and assume any
152 |       risks associated with Your exercise of permissions under this License.
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.
