No additional rights or licenses will be implied from the 143 distribution or licensing of Covered Software under this License. 144 Notwithstanding Section 2.1(b) above, no patent license is granted by a 145 Contributor: 146 147 a. for any code that a Contributor has removed from Covered Software; or 148 149 b. for infringements caused by: (i) Your and any other third party's 150 modifications of Covered Software, or (ii) the combination of its 151 Contributions with other software (except as part of its Contributor 152 Version); or 153 154 c. under Patent Claims infringed by Covered Software in the absence of 155 its Contributions. 156 157 This License does not grant any rights in the trademarks, service marks, 158 or logos of any Contributor (except as may be necessary to comply with 159 the notice requirements in Section 3.4). 160 1612.4.

Fair Use 175 176 This License is not intended to limit any rights You have under 177 applicable copyright doctrines of fair use, fair dealing, or other 178 equivalents. 179 1802.7. Conditions 181 182 Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in 183 Section 2.1. 184 185 1863. Responsibilities 187 1883.1. Distribution of Source Form 189 190 All distribution of Covered Software in Source Code Form, including any 191 Modifications that You create or to which You contribute, must be under 192 the terms of this License. You must inform recipients that the Source 193 Code Form of the Covered Software is governed by the terms of this 194 License, and how they can obtain a copy of this License. You may not 195 attempt to alter or restrict the recipients' rights in the Source Code 196 Form. 197 1983.2. Distribution of Executable Form 199 200 If You distribute Covered Software in Executable Form then: 201 202 a. such Covered Software must also be made available in Source Code Form, 203 as described in Section 3.1, and You must inform recipients of the 204 Executable Form how they can obtain a copy of such Source Code Form by 205 reasonable means in a timely manner, at a charge no more than the cost 206 of distribution to the recipient; and 207 208 b. You may distribute such Executable Form under the terms of this 209 License, or sublicense it under different terms, provided that the 210 license for the Executable Form does not attempt to limit or alter the 211 recipients' rights in the Source Code Form under this License. 212 2133.3. Distribution of a Larger Work 214 215 You may create and distribute a Larger Work under terms of Your choice, 216 provided that You also comply with the requirements of this License for 217 the Covered Software. If the Larger Work is a combination of Covered 218 Software with a work governed by one or more Secondary Licenses, and the 219 Covered Software is not Incompatible With Secondary Licenses, this 220 License permits You to additionally distribute such Covered Software 221 under the terms of such Secondary License(s), so that the recipient of 222 the Larger Work may, at their option, further distribute the Covered 223 Software under the terms of either this License or such Secondary 224 License(s). 225 2263.4. Notices 227 228 You may not remove or alter the substance of any license notices 229 (including copyright notices, patent notices, disclaimers of warranty, or 230 limitations of liability) contained within the Source Code Form of the 231 Covered Software, except that You may alter any license notices to the 232 extent required to remedy known factual inaccuracies. 233 2343.5. Application of Additional Terms 235 236 You may choose to offer, and to charge a fee for, warranty, support, 237 indemnity or liability obligations to one or more recipients of Covered 238 Software. However, You may do so only on Your own behalf, and not on 239 behalf of any Contributor. You must make it absolutely clear that any 240 such warranty, support, indemnity, or liability obligation is offered by 241 You alone, and You hereby agree to indemnify every Contributor for any 242 liability incurred by such Contributor as a result of warranty, support, 243 indemnity or liability terms You offer. You may include additional 244 disclaimers of warranty and limitations of liability specific to any 245 jurisdiction. 246 2474. Inability to Comply Due to Statute or Regulation 248 249 If it is impossible for You to comply with any of the terms of this License 250 with respect to some or all of the Covered Software due to statute, 251 judicial order, or regulation then You must: (a) comply with the terms of 252 this License to the maximum extent possible; and (b) describe the 253 limitations and the code they affect. Such description must be placed in a 254 text file included with all distributions of the Covered Software under 255 this License. Except to the extent prohibited by statute or regulation, 256 such description must be sufficiently detailed for a recipient of ordinary 257 skill to be able to understand it. 258 2595. Termination 260 2615.1. The rights granted under this License will terminate automatically if You 262 fail to comply with any of its terms. However, if You become compliant, 263 then the rights granted under this License from a particular Contributor 264 are reinstated (a) provisionally, unless and until such Contributor 265 explicitly and finally terminates Your grants, and (b) on an ongoing 266 basis, if such Contributor fails to notify You of the non-compliance by 267 some reasonable means prior to 60 days after You have come back into 268 compliance. Moreover, Your grants from a particular Contributor are 269 reinstated on an ongoing basis if such Contributor notifies You of the 270 non-compliance by some reasonable means, this is the first time You have 271 received notice of non-compliance with this License from such 272 Contributor, and You become compliant prior to 30 days after Your receipt 273 of the notice. 274 2755.2. If You initiate litigation against any entity by asserting a patent 276 infringement claim (excluding declaratory judgment actions, 277 counter-claims, and cross-claims) alleging that a Contributor Version 278 directly or indirectly infringes any patent, then the rights granted to 279 You by any and all Contributors for the Covered Software under Section 280 2.1 of this License shall terminate. 281 2825.3. In the event of termination under Sections 5.1 or 5.2 above, all end user 283 license agreements (excluding distributors and resellers) which have been 284 validly granted by You or Your distributors under this License prior to 285 termination shall survive termination. 286 2876. Disclaimer of Warranty 288 289 Covered Software is provided under this License on an "as is" basis, 290 without warranty of any kind, either expressed, implied, or statutory, 291 including, without limitation, warranties that the Covered Software is free 292 of defects, merchantable, fit for a particular purpose or non-infringing. 293 The entire risk as to the quality and performance of the Covered Software 294 is with You. Should any Covered Software prove defective in any respect, 295 You (not any Contributor) assume the cost of any necessary servicing, 296 repair, or correction. This disclaimer of warranty constitutes an essential 297 part of this License. No use of any Covered Software is authorized under 298 this License except under this disclaimer. 299 3007. Limitation of Liability 301 302 Under no circumstances and under no legal theory, whether tort (including 303 negligence), contract, or otherwise, shall any Contributor, or anyone who 304 distributes Covered Software as permitted above, be liable to You for any 305 direct, indirect, special, incidental, or consequential damages of any 306 character including, without limitation, damages for lost profits, loss of 307 goodwill, work stoppage, computer failure or malfunction, or any and all 308 other commercial damages or losses, even if such party shall have been 309 informed of the possibility of such damages. This limitation of liability 310 shall not apply to liability for death or personal injury resulting from 311 such party's negligence to the extent applicable law prohibits such 312 limitation. Some jurisdictions do not allow the exclusion or limitation of 313 incidental or consequential damages, so this exclusion and limitation may 314 not apply to You. 315 3168. Litigation 317 318 Any litigation relating to this License may be brought only in the courts 319 of a jurisdiction where the defendant maintains its principal place of 320 business and such litigation shall be governed by laws of that 321 jurisdiction, without reference to its conflict-of-law provisions. Nothing 322 in this Section shall prevent a party's ability to bring cross-claims or 323 counter-claims. 324 3259. Miscellaneous 326 327 This License represents the complete agreement concerning the subject 328 matter hereof. If any provision of this License is held to be 329 unenforceable, such provision shall be reformed only to the extent 330 necessary to make it enforceable. Any law or regulation which provides that 331 the language of a contract shall be construed against the drafter shall not 332 be used to construe this License against a Contributor. 333 334 33510. Versions of the License 336 33710.1. New Versions 338 339 Mozilla Foundation is the license steward. Except as provided in Section 340 10.3, no one other than the license steward has the right to modify or 341 publish new versions of this License. Each version will be given a 342 distinguishing version number. 343 34410.2. Effect of New Versions 345 346 You may distribute the Covered Software under the terms of the version 347 of the License under which You originally received the Covered Software, 348 or under the terms of any subsequent version published by the license 349 steward. 350 35110.3. Modified Versions 352 353 If you create software not governed by this License, and you want to 354 create a new license for such software, you may create and use a 355 modified version of this License if you rename the license and remove 356 any references to the name of the license steward (except to note that 357 such modified license differs from this License). 358 35910.4. Distributing Source Code Form that is Incompatible With Secondary 360 Licenses If You choose to distribute Source Code Form that is 361 Incompatible With Secondary Licenses under the terms of this version of 362 the License, the notice described in Exhibit B of this License must be 363 attached. 364 365Exhibit A - Source Code Form License Notice 366 367 This Source Code Form is subject to the 368 terms of the Mozilla Public License, v. 369 2.0.
