Notices 1054 | 1055 | You may not remove or alter the substance of any license notices 1056 | (including copyright notices, patent notices, disclaimers of warranty, or 1057 | limitations of liability) contained within the Source Code Form of the 1058 | Covered Software, except that You may alter any license notices to the 1059 | extent required to remedy known factual inaccuracies. 1060 | 1061 | 3.5. Application of Additional Terms 1062 | 1063 | You may choose to offer, and to charge a fee for, warranty, support, 1064 | indemnity or liability obligations to one or more recipients of Covered 1065 | Software. However, You may do so only on Your own behalf, and not on 1066 | behalf of any Contributor. You must make it absolutely clear that any 1067 | such warranty, support, indemnity, or liability obligation is offered by 1068 | You alone, and You hereby agree to indemnify every Contributor for any 1069 | liability incurred by such Contributor as a result of warranty, support, 1070 | indemnity or liability terms You offer. You may include additional 1071 | disclaimers of warranty and limitations of liability specific to any 1072 | jurisdiction. 1073 | 1074 | 4. Inability to Comply Due to Statute or Regulation 1075 | 1076 | If it is impossible for You to comply with any of the terms of this License 1077 | with respect to some or all of the Covered Software due to statute, 1078 | judicial order, or regulation then You must: (a) comply with the terms of 1079 | this License to the maximum extent possible; and (b) describe the 1080 | limitations and the code they affect. Such description must be placed in a 1081 | text file included with all distributions of the Covered Software under 1082 | this License. Except to the extent prohibited by statute or regulation, 1083 | such description must be sufficiently detailed for a recipient of ordinary 1084 | skill to be able to understand it. 1085 | 1086 | 5. Termination 1087 | 1088 | 5.1. The rights granted under this License will terminate automatically if You 1089 | fail to comply with any of its terms. However, if You become compliant, 1090 | then the rights granted under this License from a particular Contributor 1091 | are reinstated (a) provisionally, unless and until such Contributor 1092 | explicitly and finally terminates Your grants, and (b) on an ongoing 1093 | basis, if such Contributor fails to notify You of the non-compliance by 1094 | some reasonable means prior to 60 days after You have come back into 1095 | compliance. Moreover, Your grants from a particular Contributor are 1096 | reinstated on an ongoing basis if such Contributor notifies You of the 1097 | non-compliance by some reasonable means, this is the first time You have 1098 | received notice of non-compliance with this License from such 1099 | Contributor, and You become compliant prior to 30 days after Your receipt 1100 | of the notice. 1101 | 1102 | 5.2. If You initiate litigation against any entity by asserting a patent 1103 | infringement claim (excluding declaratory judgment actions, 1104 | counter-claims, and cross-claims) alleging that a Contributor Version 1105 | directly or indirectly infringes any patent, then the rights granted to 1106 | You by any and all Contributors for the Covered Software under Section 1107 | 2.1 of this License shall terminate. 1108 | 1109 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user 1110 | license agreements (excluding distributors and resellers) which have been 1111 | validly granted by You or Your distributors under this License prior to 1112 | termination shall survive termination. 1113 | 1114 | 6. Disclaimer of Warranty 1115 | 1116 | Covered Software is provided under this License on an "as is" basis, 1117 | without warranty of any kind, either expressed, implied, or statutory, 1118 | including, without limitation, warranties that the Covered Software is free 1119 | of defects, merchantable, fit for a particular purpose or non-infringing. 1120 | The entire risk as to the quality and performance of the Covered Software 1121 | is with You. Should any Covered Software prove defective in any respect, 1122 | You (not any Contributor) assume the cost of any necessary servicing, 1123 | repair, or correction. This disclaimer of warranty constitutes an essential 1124 | part of this License. No use of any Covered Software is authorized under 1125 | this License except under this disclaimer. 1126 | 1127 | 7. Limitation of Liability 1128 | 1129 | Under no circumstances and under no legal theory, whether tort (including 1130 | negligence), contract, or otherwise, shall any Contributor, or anyone who 1131 | distributes Covered Software as permitted above, be liable to You for any 1132 | direct, indirect, special, incidental, or consequential damages of any 1133 | character including, without limitation, damages for lost profits, loss of 1134 | goodwill, work stoppage, computer failure or malfunction, or any and all 1135 | other commercial damages or losses, even if such party shall have been 1136 | informed of the possibility of such damages. This limitation of liability 1137 | shall not apply to liability for death or personal injury resulting from 1138 | such party's negligence to the extent applicable law prohibits such 1139 | limitation. Some jurisdictions do not allow the exclusion or limitation of 1140 | incidental or consequential damages, so this exclusion and limitation may 1141 | not apply to You. 1142 | 1143 | 8. Litigation 1144 | 1145 | Any litigation relating to this License may be brought only in the courts 1146 | of a jurisdiction where the defendant maintains its principal place of 1147 | business and such litigation shall be governed by laws of that 1148 | jurisdiction, without reference to its conflict-of-law provisions. Nothing 1149 | in this Section shall prevent a party's ability to bring cross-claims or 1150 | counter-claims. 1151 | 1152 | 9. Miscellaneous 1153 | 1154 | This License represents the complete agreement concerning the subject 1155 | matter hereof. If any provision of this License is held to be 1156 | unenforceable, such provision shall be reformed only to the extent 1157 | necessary to make it enforceable. Any law or regulation which provides that 1158 | the language of a contract shall be construed against the drafter shall not 1159 | be used to construe this License against a Contributor. 1160 | 1161 | 1162 | 10. Versions of the License 1163 | 1164 | 10.1. New Versions 1165 | 1166 | Mozilla Foundation is the license steward. Except as provided in Section 1167 | 10.3, no one other than the license steward has the right to modify or 1168 | publish new versions of this License. Each version will be given a 1169 | distinguishing version number. 1170 | 1171 | 10.2. Effect of New Versions 1172 | 1173 | You may distribute the Covered Software under the terms of the version 1174 | of the License under which You originally received the Covered Software, 1175 | or under the terms of any subsequent version published by the license 1176 | steward. 1177 | 1178 | 10.3. Modified Versions 1179 | 1180 | If you create software not governed by this License, and you want to 1181 | create a new license for such software, you may create and use a 1182 | modified version of this License if you rename the license and remove 1183 | any references to the name of the license steward (except to note that 1184 | such modified license differs from this License). 1185 | 1186 | 10.4.
