| 42 | +shall not include works that remain separable from, or merely link (or bind by |
| 43 | +name) to the interfaces of, the Work and Derivative Works thereof. |
| 44 | + |

| 77 | +that are necessarily infringed by their Contribution(s) alone or by combination |
| 78 | +of their Contribution(s) with the Work to which such Contribution(s) was |

| 80 | +cross-claim or counterclaim in a lawsuit) alleging that the Work or a |
| 81 | +Contribution incorporated within the Work constitutes direct or contributory |
| 82 | +patent infringement, then any patent licenses granted to You under this License |
| 83 | +for that Work shall terminate as of the date such litigation is filed. |
| 84 | + |
| 85 | +#### 4. Redistribution |
| 86 | + |
| 87 | +You may reproduce and distribute copies of the Work or Derivative Works thereof |

| 92 | + this License; and |
| 93 | +- **(b)** You must cause any modified files to carry prominent notices stating that You |
| 94 | + changed the files; and |
| 95 | +- **(c)** You must retain, in the Source form of any Derivative Works that You distribute, |
| 96 | + all copyright, patent, trademark, and attribution notices from the Source form |
| 97 | + of the Work, excluding those notices that do not pertain to any part of the |
| 98 | + Derivative Works; and |
| 99 | +- **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any |
| 100 | + Derivative Works that You distribute must include a readable copy of the |
| 101 | + attribution notices contained within such NOTICE file, excluding those notices |
| 102 | + that do not pertain to any part of the Derivative Works, in at least one of the |
| 103 | + following places: within a NOTICE text file distributed as part of the |
| 104 | + Derivative Works; within the Source form or documentation, if provided along |
| 105 | + with the Derivative Works; or, within a display generated by the Derivative |
| 106 | + Works, if and wherever such third-party notices normally appear. The contents of |
| 107 | + the NOTICE file are for informational purposes only and do not modify the |
| 108 | + License. You may add Your own attribution notices within Derivative Works that |
| 109 | + You distribute, alongside or as an addendum to the NOTICE text from the Work, |
| 110 | + provided that such additional attribution notices cannot be construed as |
| 111 | + modifying the License. |
| 112 | + |
| 113 | +You may add Your own copyright statement to Your modifications and may provide |
| 114 | +additional or different license terms and conditions for use, reproduction, or |
| 115 | +distribution of Your modifications, or for any such Derivative Works as a whole, |
| 116 | +provided Your use, reproduction, and distribution of the Work otherwise complies |
| 117 | +with the conditions stated in this License. |
| 118 | + |
| 119 | +#### 5. Submission of Contributions |
| 120 | + |
| 121 | +Unless You explicitly state otherwise, any Contribution intentionally submitted |
| 122 | +for inclusion in the Work by You to the Licensor shall be under the terms and |
| 123 | +conditions of this License, without any additional terms or conditions. |
| 124 | +Notwithstanding the above, nothing herein shall supersede or modify the terms of |
| 125 | +any separate license agreement you may have executed with Licensor regarding |
| 126 | +such Contributions. |
| 127 | + |
| 128 | +#### 6. Trademarks |
| 129 | + |
| 130 | +This License does not grant permission to use the trade names, trademarks, |
| 131 | +service marks, or product names of the Licensor, except as required for |
| 132 | +reasonable and customary use in describing the origin of the Work and |
| 133 | +reproducing the content of the NOTICE file. |
| 134 | + |
| 135 | +#### 7. Disclaimer of Warranty |
| 136 | + |
| 137 | +Unless required by applicable law or agreed to in writing, Licensor provides the |
| 138 | +Work (and each Contributor provides its Contributions) on an “AS IS” BASIS, |
| 139 | +WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, |
| 140 | +including, without limitation, any warranties or conditions of TITLE, |
| 141 | +NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are |
| 142 | +solely responsible for determining the appropriateness of using or |
| 143 | +redistributing the Work and assume any risks associated with Your exercise of |
| 144 | +permissions under this License. |
| 145 | + |
| 146 | +#### 8. Limitation of Liability |
| 147 | + |
| 148 | +In no event and under no legal theory, whether in tort (including negligence), |
| 149 | +contract, or otherwise, unless required by applicable law (such as deliberate |
| 150 | +and grossly negligent acts) or agreed to in writing, shall any Contributor be |
| 151 | +liable to You for damages, including any direct, indirect, special, incidental, |
| 152 | +or consequential damages of any character arising as a result of this License or |
| 153 | +out of the use or inability to use the Work (including but not limited to |
| 154 | +damages for loss of goodwill, work stoppage, computer failure or malfunction, or |
| 155 | +any and all other commercial damages or losses), even if such Contributor has |
| 156 | +been advised of the possibility of such damages. |
| 157 | + |
| 158 | +#### 9. Accepting Warranty or Additional Liability |
| 159 | + |
| 160 | +While redistributing the Work or Derivative Works thereof, You may choose to |
| 161 | +offer, and charge a fee for, acceptance of support, warranty, indemnity, or |
| 162 | +other liability obligations and/or rights consistent with this License. However, |
| 163 | +in accepting such obligations, You may act only on Your own behalf and on Your |
| 164 | +sole responsibility, not on behalf of any other Contributor, and only if You |
| 165 | +agree to indemnify, defend, and hold each Contributor harmless for any liability |
| 166 | +incurred by, or claims asserted against, such Contributor by reason of your |
| 167 | +accepting any such warranty or additional liability. |
