   1.141 +permitted under the terms of Section 3.3).
   1.142 +
   1.143 +2.5. Representation
   1.144 +
   1.145 +Each Contributor represents that the Contributor believes its

   1.161 +-------------------
   1.162 +
   1.163 +3.1. Distribution of Source Form
   1.164 +
   1.165 +All distribution of Covered Software in Source Code Form, including any
   1.166 +Modifications that You create or to which You contribute, must be under
   1.167 +the terms of this License. You must inform recipients that the Source
   1.168 +Code Form of the Covered Software is governed by the terms of this
   1.169 +License, and how they can obtain a copy of this License. You may not
   1.170 +attempt to alter or restrict the recipients' rights in the Source Code
   1.171 +Form.
   1.172 +
   1.173 +3.2. Distribution of Executable Form
   1.174 +
   1.175 +If You distribute Covered Software in Executable Form then:
   1.176 +
   1.177 +(a) such Covered Software must also be made available in Source Code
   1.178 +    Form, as described in Section 3.1, and You must inform recipients of
   1.179 +    the Executable Form how they can obtain a copy of such Source Code
   1.180 +    Form by reasonable means in a timely manner, at a charge no more
   1.181 +    than the cost of distribution to the recipient; and
   1.182 +
   1.183 +(b) You may distribute such Executable Form under the terms of this
   1.184 +    License, or sublicense it under different terms, provided that the
   1.185 +    license for the Executable Form does not attempt to limit or alter
   1.186 +    the recipients' rights in the Source Code Form under this License.
   1.187 +
   1.188 +3.3. Distribution of a Larger Work
   1.189 +
   1.190 +You may create and distribute a Larger Work under terms of Your choice,
   1.191 +provided that You also comply with the requirements of this License for
   1.192 +the Covered Software. If the Larger Work is a combination of Covered
   1.193 +Software with a work governed by one or more Secondary Licenses, and the
   1.194 +Covered Software is not Incompatible With Secondary Licenses, this
   1.195 +License permits You to additionally distribute such Covered Software
   1.196 +under the terms of such Secondary License(s), so that the recipient of
   1.197 +the Larger Work may, at their option, further distribute the Covered
   1.198 +Software under the terms of either this License or such Secondary
   1.199 +License(s).
   1.200 +
   1.201 +3.4. Notices
   1.202 +
   1.203 +You may not remove or alter the substance of any license notices
   1.204 +(including copyright notices, patent notices, disclaimers of warranty,
   1.205 +or limitations of liability) contained within the Source Code Form of
   1.206 +the Covered Software, except that You may alter any license notices to
   1.207 +the extent required to remedy known factual inaccuracies.
   1.208 +
   1.209 +3.5. Application of Additional Terms
   1.210 +
   1.211 +You may choose to offer, and to charge a fee for, warranty, support,
   1.212 +indemnity or liability obligations to one or more recipients of Covered
   1.213 +Software. However, You may do so only on Your own behalf, and not on
   1.214 +behalf of any Contributor. You must make it absolutely clear that any
   1.215 +such warranty, support, indemnity, or liability obligation is offered by
   1.216 +You alone, and You hereby agree to indemnify every Contributor for any
   1.217 +liability incurred by such Contributor as a result of warranty, support,
   1.218 +indemnity or liability terms You offer. You may include additional
   1.219 +disclaimers of warranty and limitations of liability specific to any
   1.220 +jurisdiction.
   1.221 +
   1.222 +4. Inability to Comply Due to Statute or Regulation
   1.223 +---------------------------------------------------
   1.224 +
   1.225 +If it is impossible for You to comply with any of the terms of this
   1.226 +License with respect to some or all of the Covered Software due to
   1.227 +statute, judicial order, or regulation then You must: (a) comply with
   1.228 +the terms of this License to the maximum extent possible; and (b)
   1.229 +describe the limitations and the code they affect. Such description must
   1.230 +be placed in a text file included with all distributions of the Covered
   1.231 +Software under this License. Except to the extent prohibited by statute
   1.232 +or regulation, such description must be sufficiently detailed for a
   1.233 +recipient of ordinary skill to be able to understand it.
   1.234 +
   1.235 +5. Termination
   1.236 +--------------
   1.237 +
   1.238 +5.1. The rights granted under this License will terminate automatically
   1.239 +if You fail to comply with any of its terms. However, if You become
   1.240 +compliant, then the rights granted under this License from a particular
   1.241 +Contributor are reinstated (a) provisionally, unless and until such
   1.242 +Contributor explicitly and finally terminates Your grants, and (b) on an
   1.243 +ongoing basis, if such Contributor fails to notify You of the
   1.244 +non-compliance by some reasonable means prior to 60 days after You have
   1.245 +come back into compliance. Moreover, Your grants from a particular
   1.246 +Contributor are reinstated on an ongoing basis if such Contributor
   1.247 +notifies You of the non-compliance by some reasonable means, this is the
   1.248 +first time You have received notice of non-compliance with this License
   1.249 +from such Contributor, and You become compliant prior to 30 days after
   1.250 +Your receipt of the notice.
   1.251 +
   1.252 +5.2. If You initiate litigation against any entity by asserting a patent
   1.253 +infringement claim (excluding declaratory judgment actions,
   1.254 +counter-claims, and cross-claims) alleging that a Contributor Version
   1.255 +directly or indirectly infringes any patent, then the rights granted to
   1.256 +You by any and all Contributors for the Covered Software under Section
   1.257 +2.1 of this License shall terminate.
   1.258 +
   1.259 +5.3. In the event of termination under Sections 5.1 or 5.2 above, all
   1.260 +end user license agreements (excluding distributors and resellers) which
   1.261 +have been validly granted by You or Your distributors under this License
   1.262 +prior to termination shall survive termination.

   1.309 +Any litigation relating to this License may be brought only in the
   1.310 +courts of a jurisdiction where the defendant maintains its principal
   1.311 +place of business and such litigation shall be governed by laws of that
   1.312 +jurisdiction, without reference to its conflict-of-law provisions.

   1.321 +unenforceable, such provision shall be reformed only to the extent
   1.322 +necessary to make it enforceable. Any law or regulation which provides
   1.323 +that the language of a contract shall be construed against the drafter

   1.342 +
   1.343 +10.3. Modified Versions
   1.344 +
   1.345 +If you create software not governed by this License, and you want to
   1.346 +create a new license for such software, you may create and use a
   1.347 +modified version of this License if you rename the license and remove
   1.348 +any references to the name of the license steward (except to note that
   1.349 +such modified license differs from this License).
   1.350 +
   1.351 +10.4. Distributing Source Code Form that is Incompatible With Secondary
   1.352 +Licenses
