209distribute the Covered Software under a subsequent version of this

229
2303. Responsibilities
231-------------------
232
2333.1. Distribution of Source Form
234
235All distribution of Covered Software in Source Code Form, including any
236Modifications that You create or to which You contribute, must be under
237the terms of this License. You must inform recipients that the Source
238Code Form of the Covered Software is governed by the terms of this
239License, and how they can obtain a copy of this License. You may not
240attempt to alter or restrict the recipients' rights in the Source Code
241Form.
242
2433.2. Distribution of Executable Form
244
245If You distribute Covered Software in Executable Form then:
246
247(a) such Covered Software must also be made available in Source Code
248 Form, as described in Section 3.1, and You must inform recipients of
249 the Executable Form how they can obtain a copy of such Source Code
250 Form by reasonable means in a timely manner, at a charge no more
251 than the cost of distribution to the recipient; and
252
253(b) You may distribute such Executable Form under the terms of this
254 License, or sublicense it under different terms, provided that the
255 license for the Executable Form does not attempt to limit or alter
256 the recipients' rights in the Source Code Form under this License.
257
2583.3. Distribution of a Larger Work
259
260You may create and distribute a Larger Work under terms of Your choice,
261provided that You also comply with the requirements of this License for
262the Covered Software. If the Larger Work is a combination of Covered
263Software with a work governed by one or more Secondary Licenses, and the
264Covered Software is not Incompatible With Secondary Licenses, this
265License permits You to additionally distribute such Covered Software
266under the terms of such Secondary License(s), so that the recipient of
267the Larger Work may, at their option, further distribute the Covered
268Software under the terms of either this License or such Secondary
269License(s).
270
2713.4. Notices
272
273You may not remove or alter the substance of any license notices
274(including copyright notices, patent notices, disclaimers of warranty,
275or limitations of liability) contained within the Source Code Form of
276the Covered Software, except that You may alter any license notices to
277the extent required to remedy known factual inaccuracies.
278
2793.5. Application of Additional Terms
280
281You may choose to offer, and to charge a fee for, warranty, support,
282indemnity or liability obligations to one or more recipients of Covered
283Software. However, You may do so only on Your own behalf, and not on
284behalf of any Contributor. You must make it absolutely clear that any
285such warranty, support, indemnity, or liability obligation is offered by
286You alone, and You hereby agree to indemnify every Contributor for any
287liability incurred by such Contributor as a result of warranty, support,
288indemnity or liability terms You offer. You may include additional
289disclaimers of warranty and limitations of liability specific to any
290jurisdiction.
291
2924. Inability to Comply Due to Statute or Regulation
293---------------------------------------------------
294
295If it is impossible for You to comply with any of the terms of this
296License with respect to some or all of the Covered Software due to
297statute, judicial order, or regulation then You must: (a) comply with
298the terms of this License to the maximum extent possible; and (b)
299describe the limitations and the code they affect. Such description must
300be placed in a text file included with all distributions of the Covered
301Software under this License. Except to the extent prohibited by statute
302or regulation, such description must be sufficiently detailed for a
303recipient of ordinary skill to be able to understand it.
304
3055. Termination
306--------------
307
3085.1. The rights granted under this License will terminate automatically
309if You fail to comply with any of its terms. However, if You become
310compliant, then the rights granted under this License from a particular
311Contributor are reinstated (a) provisionally, unless and until such
312Contributor explicitly and finally terminates Your grants, and (b) on an
313ongoing basis, if such Contributor fails to notify You of the
314non-compliance by some reasonable means prior to 60 days after You have
315come back into compliance. Moreover, Your grants from a particular
316Contributor are reinstated on an ongoing basis if such Contributor
317notifies You of the non-compliance by some reasonable means, this is the
318first time You have received notice of non-compliance with this License
319from such Contributor, and You become compliant prior to 30 days after
320Your receipt of the notice.
321
3225.2. If You initiate litigation against any entity by asserting a patent
323infringement claim (excluding declaratory judgment actions,
324counter-claims, and cross-claims) alleging that a Contributor Version
325directly or indirectly infringes any patent, then the rights granted to
326You by any and all Contributors for the Covered Software under Section
3272.1 of this License shall terminate.
328
3295.3. In the event of termination under Sections 5.1 or 5.2 above, all
330end user license agreements (excluding distributors and resellers) which
331have been validly granted by You or Your distributors under this License
332prior to termination shall survive termination.

339* Covered Software is provided under this License on an "as is" *
340* basis, without warranty of any kind, either expressed, implied, or *
341* statutory, including, without limitation, warranties that the *
342* Covered Software is free of defects, merchantable, fit for a *
343* particular purpose or non-infringing. The entire risk as to the *

355* 7. Limitation of Liability *
356* -------------------------- *
357* *
358* Under no circumstances and under no legal theory, whether tort *
359* (including negligence), contract, or otherwise, shall any *
360* Contributor, or anyone who distributes Covered Software as *
361* permitted above, be liable to You for any direct, indirect, *
362* special, incidental, or consequential damages of any character *
363* including, without limitation, damages for lost profits, loss of *
364* goodwill, work stoppage, computer failure or malfunction, or any *
365* and all other commercial damages or losses, even if such party *
366* shall have been informed of the possibility of such damages. This *
367* limitation of liability shall not apply to liability for death or *
368* personal injury resulting from such party's negligence to the *
369* extent applicable law prohibits such limitation. Some *
370* jurisdictions do not allow the exclusion or limitation of *
371* incidental or consequential damages, so this exclusion and *
372* limitation may not apply to You. *
