 120
 121      The licenses granted in Section 2.1 with respect to any Contribution
 122      become effective for each Contribution on the date the Contributor first
 123      distributes such Contribution.
 124
 125 2.3. Limitations on Grant Scope
 126
 127      The licenses granted in this Section 2 are the only rights granted under
 128      this License. No additional rights or licenses will be implied from the
 129      distribution or licensing of Covered Software under this License.
 130      Notwithstanding Section 2.1(b) above, no patent license is granted by a
 131      Contributor:
 132
 133      a. for any code that a Contributor has removed from Covered Software; or

 135      b. for infringements caused by: (i) Your and any other third party's

 142
 143      This License does not grant any rights in the trademarks, service marks,
 144      or logos of any Contributor (except as may be necessary to comply with
 145      the notice requirements in Section 3.4).
 146
 147 2.4. Subsequent Licenses
 148
 149      No Contributor makes additional grants as a result of Your choice to
 150      distribute the Covered Software under a subsequent version of this
 151      License (see Section 10.2) or under the terms of a Secondary License (if
 152      permitted under the terms of Section 3.3).
 153
 154 2.5. Representation
 155
 156      Each Contributor represents that the Contributor believes its
 157      Contributions are its original creation(s) or it has sufficient rights to
 158      grant the rights to its Contributions conveyed by this License.
 159
 160 2.6. Fair Use
 161
 162      This License is not intended to limit any rights You have under
 163      applicable copyright doctrines of fair use, fair dealing, or other
 164      equivalents.
 165
 166 2.7. Conditions
 167
 168      Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
 169      Section 2.1.
 170
 171
 172 3. Responsibilities
 173
 174 3.1. Distribution of Source Form
 175
 176      All distribution of Covered Software in Source Code Form, including any
 177      Modifications that You create or to which You contribute, must be under
 178      the terms of this License. You must inform recipients that the Source
 179      Code Form of the Covered Software is governed by the terms of this
 180      License, and how they can obtain a copy of this License. You may not
 181      attempt to alter or restrict the recipients' rights in the Source Code
 182      Form.
 183
 184 3.2. Distribution of Executable Form
 185
 186      If You distribute Covered Software in Executable Form then:
 187
 188      a. such Covered Software must also be made available in Source Code Form,
 189         as described in Section 3.1, and You must inform recipients of the
 190         Executable Form how they can obtain a copy of such Source Code Form by
 191         reasonable means in a timely manner, at a charge no more than the cost
 192         of distribution to the recipient; and
 193
 194      b. You may distribute such Executable Form under the terms of this
 195         License, or sublicense it under different terms, provided that the
 196         license for the Executable Form does not attempt to limit or alter the
 197         recipients' rights in the Source Code Form under this License.
 198
 199 3.3. Distribution of a Larger Work
 200
 201      You may create and distribute a Larger Work under terms of Your choice,
 202      provided that You also comply with the requirements of this License for
 203      the Covered Software. If the Larger Work is a combination of Covered
 204      Software with a work governed by one or more Secondary Licenses, and the
 205      Covered Software is not Incompatible With Secondary Licenses, this
 206      License permits You to additionally distribute such Covered Software
 207      under the terms of such Secondary License(s), so that the recipient of
 208      the Larger Work may, at their option, further distribute the Covered
 209      Software under the terms of either this License or such Secondary
 210      License(s).
 211
 212 3.4. Notices
 213
 214      You may not remove or alter the substance of any license notices
 215      (including copyright notices, patent notices, disclaimers of warranty, or
 216      limitations of liability) contained within the Source Code Form of the
 217      Covered Software, except that You may alter any license notices to the
 218      extent required to remedy known factual inaccuracies.
 219
 220 3.5. Application of Additional Terms
 221
 222      You may choose to offer, and to charge a fee for, warranty, support,
 223      indemnity or liability obligations to one or more recipients of Covered
 224      Software. However, You may do so only on Your own behalf, and not on
 225      behalf of any Contributor. You must make it absolutely clear that any
 226      such warranty, support, indemnity, or liability obligation is offered by
 227      You alone, and You hereby agree to indemnify every Contributor for any
 228      liability incurred by such Contributor as a result of warranty, support,
 229      indemnity or liability terms You offer. You may include additional
 230      disclaimers of warranty and limitations of liability specific to any
 231      jurisdiction.
 232
 233 4. Inability to Comply Due to Statute or Regulation
 234
 235    If it is impossible for You to comply with any of the terms of this License
 236    with respect to some or all of the Covered Software due to statute,
 237    judicial order, or regulation then You must: (a) comply with the terms of
 238    this License to the maximum extent possible; and (b) describe the
 239    limitations and the code they affect. Such description must be placed in a
 240    text file included with all distributions of the Covered Software under
 241    this License. Except to the extent prohibited by statute or regulation,
 242    such description must be sufficiently detailed for a recipient of ordinary
 243    skill to be able to understand it.
 244
 245 5. Termination
 246
 247 5.1. The rights granted under this License will terminate automatically if You
 248      fail to comply with any of its terms. However, if You become compliant,
 249      then the rights granted under this License from a particular Contributor
 250      are reinstated (a) provisionally, unless and until such Contributor
 251      explicitly and finally terminates Your grants, and (b) on an ongoing
 252      basis, if such Contributor fails to notify You of the non-compliance by
 253      some reasonable means prior to 60 days after You have come back into
 254      compliance. Moreover, Your grants from a particular Contributor are
 255      reinstated on an ongoing basis if such Contributor notifies You of the
 256      non-compliance by some reasonable means, this is the first time You have
 257      received notice of non-compliance with this License from such
 258      Contributor, and You become compliant prior to 30 days after Your receipt
 259      of the notice.
 260
 261 5.2. If You initiate litigation against any entity by asserting a patent
 262      infringement claim (excluding declaratory judgment actions,
 263      counter-claims, and cross-claims) alleging that a Contributor Version
 264      directly or indirectly infringes any patent, then the rights granted to
 265      You by any and all Contributors for the Covered Software under Section
 266      2.1 of this License shall terminate.
 267
 268 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
 269      license agreements (excluding distributors and resellers) which have been
 270      validly granted by You or Your distributors under this License prior to
 271      termination shall survive termination.
 272
 273 6. Disclaimer of Warranty
 274
 275    Covered Software is provided under this License on an "as is" basis,
 276    without warranty of any kind, either expressed, implied, or statutory,
 277    including, without limitation, warranties that the Covered Software is free
 278    of defects, merchantable, fit for a particular purpose or non-infringing.
 279    The entire risk as to the quality and performance of the Covered Software
 280    is with You. Should any Covered Software prove defective in any respect,
 281    You (not any Contributor) assume the cost of any necessary servicing,
 282    repair, or correction. This disclaimer of warranty constitutes an essential
 283    part of this License. No use of  any Covered Software is authorized under
 284    this License except under this disclaimer.
 285
 286 7. Limitation of Liability
 287
 288    Under no circumstances and under no legal theory, whether tort (including
 289    negligence), contract, or otherwise, shall any Contributor, or anyone who
 290    distributes Covered Software as permitted above, be liable to You for any
 291    direct, indirect, special, incidental, or consequential damages of any
 292    character including, without limitation, damages for lost profits, loss of
 293    goodwill, work stoppage, computer failure or malfunction, or any and all
 294    other commercial damages or losses, even if such party shall have been
 295    informed of the possibility of such damages. This limitation of liability
 296    shall not apply to liability for death or personal injury resulting from
 297    such party's negligence to the extent applicable law prohibits such
 298    limitation. Some jurisdictions do not allow the exclusion or limitation of
 299    incidental or consequential damages, so this exclusion and limitation may
 300    not apply to You.
 301
 302 8. Litigation
 303
 304    Any litigation relating to this License may be brought only in the courts
 305    of a jurisdiction where the defendant maintains its principal place of
 306    business and such litigation shall be governed by laws of that
 307    jurisdiction, without reference to its conflict-of-law provisions. Nothing
 308    in this Section shall prevent a party's ability to bring cross-claims or
 309    counter-claims.
 310
 311 9. Miscellaneous
 312
 313    This License represents the complete agreement concerning the subject
 314    matter hereof. If any provision of this License is held to be
 315    unenforceable, such provision shall be reformed only to the extent
 316    necessary to make it enforceable. Any law or regulation which provides that
 317    the language of a contract shall be construed against the drafter shall not
 318    be used to construe this License against a Contributor.
 319
 320
 321 10. Versions of the License
 322
 323 10.1. New Versions
 324
 325       Mozilla Foundation is the license steward. Except as provided in Section
 326       10.3, no one other than the license steward has the right to modify or
 327       publish new versions of this License. Each version will be given a
 328       distinguishing version number.
 329
 330 10.2. Effect of New Versions
 331
 332       You may distribute the Covered Software under the terms of the version
 333       of the License under which You originally received the Covered Software,
 334       or under the terms of any subsequent version published by the license
 335       steward.
 336
 337 10.3. Modified Versions
 338
 339       If you create software not governed by this License, and you want to
 340       create a new license for such software, you may create and use a
 341       modified version of this License if you rename the license and remove
 342       any references to the name of the license steward (except to note that
 343       such modified license differs from this License).
 344
 345 10.4. Distributing Source Code Form that is Incompatible With Secondary
 346       Licenses If You choose to distribute Source Code Form that is
 347       Incompatible With Secondary Licenses under the terms of this version of
 348       the License, the notice described in Exhibit B of this License must be
 349       attached.

 360 If it is not possible or desirable to put the notice in a particular file,
 361 then You may include the notice in a location (such as a LICENSE file in a
 362 relevant directory) where a recipient would be likely to look for such a
 363 notice.
