103
+
Licensable by such Contributor to use, reproduce, make available,

112
+
2.2. Effective Date
113
+
114
+
The licenses granted in Section 2.1 with respect to any Contribution
115
+
become effective for each Contribution on the date the Contributor first
116
+
distributes such Contribution.
117
+
118
+
2.3. Limitations on Grant Scope
119
+
120
+
The licenses granted in this Section 2 are the only rights granted under
121
+
this License. No additional rights or licenses will be implied from the
122
+
distribution or licensing of Covered Software under this License.
123
+
Notwithstanding Section 2.1(b) above, no patent license is granted by a
124
+
Contributor:
125
+
126
+
a. for any code that a Contributor has removed from Covered Software; or

133
+
c. under Patent Claims infringed by Covered Software in the absence of
134
+
its Contributions.
135
+
136
+
This License does not grant any rights in the trademarks, service marks,
137
+
or logos of any Contributor (except as may be necessary to comply with
138
+
the notice requirements in Section 3.4).
139
+
140
+
2.4. Subsequent Licenses
141
+
142
+
No Contributor makes additional grants as a result of Your choice to
143
+
distribute the Covered Software under a subsequent version of this
144
+
License (see Section 10.2) or under the terms of a Secondary License (if
145
+
permitted under the terms of Section 3.3).
146
+
147
+
2.5. Representation
148
+
149
+
Each Contributor represents that the Contributor believes its
150
+
Contributions are its original creation(s) or it has sufficient rights to
151
+
grant the rights to its Contributions conveyed by this License.
152
+
153
+
2.6. Fair Use
154
+
155
+
This License is not intended to limit any rights You have under
156
+
applicable copyright doctrines of fair use, fair dealing, or other
157
+
equivalents.
158
+
159
+
2.7. Conditions
160
+
161
+
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
162
+
Section 2.1.
163
+
164
+
165
+
3. Responsibilities
166
+
167
+
3.1. Distribution of Source Form
168
+
169
+
All distribution of Covered Software in Source Code Form, including any
170
+
Modifications that You create or to which You contribute, must be under
171
+
the terms of this License. You must inform recipients that the Source
172
+
Code Form of the Covered Software is governed by the terms of this
173
+
License, and how they can obtain a copy of this License. You may not
174
+
attempt to alter or restrict the recipients' rights in the Source Code
175
+
Form.
176
+
177
+
3.2. Distribution of Executable Form
178
+
179
+
If You distribute Covered Software in Executable Form then:
180
+
181
+
a. such Covered Software must also be made available in Source Code Form,
182
+
as described in Section 3.1, and You must inform recipients of the
183
+
Executable Form how they can obtain a copy of such Source Code Form by
184
+
reasonable means in a timely manner, at a charge no more than the cost
185
+
of distribution to the recipient; and
186
+
187
+
b. You may distribute such Executable Form under the terms of this
188
+
License, or sublicense it under different terms, provided that the
189
+
license for the Executable Form does not attempt to limit or alter the
190
+
recipients' rights in the Source Code Form under this License.
191
+
192
+
3.3. Distribution of a Larger Work
193
+
194
+
You may create and distribute a Larger Work under terms of Your choice,
195
+
provided that You also comply with the requirements of this License for
196
+
the Covered Software. If the Larger Work is a combination of Covered
197
+
Software with a work governed by one or more Secondary Licenses, and the
198
+
Covered Software is not Incompatible With Secondary Licenses, this
199
+
License permits You to additionally distribute such Covered Software
200
+
under the terms of such Secondary License(s), so that the recipient of
201
+
the Larger Work may, at their option, further distribute the Covered
202
+
Software under the terms of either this License or such Secondary
203
+
License(s).
204
+
205
+
3.4. Notices
206
+
207
+
You may not remove or alter the substance of any license notices
208
+
(including copyright notices, patent notices, disclaimers of warranty, or
209
+
limitations of liability) contained within the Source Code Form of the
210
+
Covered Software, except that You may alter any license notices to the
211
+
extent required to remedy known factual inaccuracies.
212
+
213
+
3.5. Application of Additional Terms
214
+
215
+
You may choose to offer, and to charge a fee for, warranty, support,
216
+
indemnity or liability obligations to one or more recipients of Covered
217
+
Software. However, You may do so only on Your own behalf, and not on
218
+
behalf of any Contributor. You must make it absolutely clear that any
219
+
such warranty, support, indemnity, or liability obligation is offered by
220
+
You alone, and You hereby agree to indemnify every Contributor for any
221
+
liability incurred by such Contributor as a result of warranty, support,
222
+
indemnity or liability terms You offer. You may include additional
223
+
disclaimers of warranty and limitations of liability specific to any
224
+
jurisdiction.
225
+
226
+
4. Inability to Comply Due to Statute or Regulation
227
+
228
+
If it is impossible for You to comply with any of the terms of this License
229
+
with respect to some or all of the Covered Software due to statute,
230
+
judicial order, or regulation then You must: (a) comply with the terms of
231
+
this License to the maximum extent possible; and (b) describe the
232
+
limitations and the code they affect. Such description must be placed in a
233
+
text file included with all distributions of the Covered Software under
234
+
this License. Except to the extent prohibited by statute or regulation,
235
+
such description must be sufficiently detailed for a recipient of ordinary
236
+
skill to be able to understand it.
237
+
238
+
5. Termination
239
+
240
+
5.1. The rights granted under this License will terminate automatically if You
241
+
fail to comply with any of its terms. However, if You become compliant,
242
+
then the rights granted under this License from a particular Contributor
243
+
are reinstated (a) provisionally, unless and until such Contributor
244
+
explicitly and finally terminates Your grants, and (b) on an ongoing
245
+
basis, if such Contributor fails to notify You of the non-compliance by
246
+
some reasonable means prior to 60 days after You have come back into
247
+
compliance. Moreover, Your grants from a particular Contributor are
248
+
reinstated on an ongoing basis if such Contributor notifies You of the
249
+
non-compliance by some reasonable means, this is the first time You have
250
+
received notice of non-compliance with this License from such
251
+
Contributor, and You become compliant prior to 30 days after Your receipt
252
+
of the notice.
253
+
254
+
5.2. If You initiate litigation against any entity by asserting a patent
255
+
infringement claim (excluding declaratory judgment actions,
256
+
counter-claims, and cross-claims) alleging that a Contributor Version
257
+
directly or indirectly infringes any patent, then the rights granted to
258
+
You by any and all Contributors for the Covered Software under Section
259
+
2.1 of this License shall terminate.
260
+
261
+
5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
262
+
license agreements (excluding distributors and resellers) which have been
263
+
validly granted by You or Your distributors under this License prior to
264
+
termination shall survive termination.
265
+
266
+
6. Disclaimer of Warranty
267
+
268
+
Covered Software is provided under this License on an "as is" basis,
269
+
without warranty of any kind, either expressed, implied, or statutory,
270
+
including, without limitation, warranties that the Covered Software is free
271
+
of defects, merchantable, fit for a particular purpose or non-infringing.
272
+
The entire risk as to the quality and performance of the Covered Software
273
+
is with You. Should any Covered Software prove defective in any respect,
274
+
You (not any Contributor) assume the cost of any necessary servicing,
275
+
repair, or correction. This disclaimer of warranty constitutes an essential
276
+
part of this License. No use of any Covered Software is authorized under
277
+
this License except under this disclaimer.
278
+
279
+
7. Limitation of Liability
280
+
281
+
Under no circumstances and under no legal theory, whether tort (including
282
+
negligence), contract, or otherwise, shall any Contributor, or anyone who
283
+
distributes Covered Software as permitted above, be liable to You for any
284
+
direct, indirect, special, incidental, or consequential damages of any
285
+
character including, without limitation, damages for lost profits, loss of
286
+
goodwill, work stoppage, computer failure or malfunction, or any and all
287
+
other commercial damages or losses, even if such party shall have been
288
+
informed of the possibility of such damages. This limitation of liability
289
+
shall not apply to liability for death or personal injury resulting from
290
+
such party's negligence to the extent applicable law prohibits such
291
+
limitation. Some jurisdictions do not allow the exclusion or limitation of
292
+
incidental or consequential damages, so this exclusion and limitation may
293
+
not apply to You.
294
+
295
+
8. Litigation
296
+
297
+
Any litigation relating to this License may be brought only in the courts
298
+
of a jurisdiction where the defendant maintains its principal place of
299
+
business and such litigation shall be governed by laws of that
300
+
jurisdiction, without reference to its conflict-of-law provisions. Nothing
301
+
in this Section shall prevent a party's ability to bring cross-claims or
302
+
counter-claims.
303
+
304
+
9. Miscellaneous
305
+
306
+
This License represents the complete agreement concerning the subject
307
+
matter hereof. If any provision of this License is held to be
308
+
unenforceable, such provision shall be reformed only to the extent
309
+
necessary to make it enforceable. Any law or regulation which provides that
310
+
the language of a contract shall be construed against the drafter shall not
311
+
be used to construe this License against a Contributor.
312
+
313
+
314
+
10. Versions of the License
315
+
316
+
10.1. New Versions
317
+
318
+
Mozilla Foundation is the license steward. Except as provided in Section
319
+
10.3, no one other than the license steward has the right to modify or
320
+
publish new versions of this License. Each version will be given a
321
+
distinguishing version number.
322
+
323
+
10.2. Effect of New Versions
324
+
325
+
You may distribute the Covered Software under the terms of the version
326
+
of the License under which You originally received the Covered Software,
327
+
or under the terms of any subsequent version published by the license
328
+
steward.
329
+
330
+
10.3. Modified Versions
331
+
332
+
If you create software not governed by this License, and you want to
333
+
create a new license for such software, you may create and use a
334
+
modified version of this License if you rename the license and remove
335
+
any references to the name of the license steward (except to note that
336
+
such modified license differs from this License).
337
+
338
+
10.4. Distributing Source Code Form that is Incompatible With Secondary
339
+
Licenses If You choose to distribute Source Code Form that is
340
+
Incompatible With Secondary Licenses under the terms of this version of
341
+
the License, the notice described in Exhibit B of this License must be
342
+
attached.
