Except to the extent prohibited by statute or regulation, + such description must be sufficiently detailed for a recipient of ordinary + skill to be able to understand it. + +5. Termination + +5.1. The rights granted under this License will terminate automatically if You + fail to comply with any of its terms. However, if You become compliant, + then the rights granted under this License from a particular Contributor + are reinstated (a) provisionally, unless and until such Contributor + explicitly and finally terminates Your grants, and (b) on an ongoing + basis, if such Contributor fails to notify You of the non-compliance by + some reasonable means prior to 60 days after You have come back into + compliance. Moreover, Your grants from a particular Contributor are + reinstated on an ongoing basis if such Contributor notifies You of the + non-compliance by some reasonable means, this is the first time You have + received notice of non-compliance with this License from such + Contributor, and You become compliant prior to 30 days after Your receipt + of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent + infringement claim (excluding declaratory judgment actions, + counter-claims, and cross-claims) alleging that a Contributor Version + directly or indirectly infringes any patent, then the rights granted to + You by any and all Contributors for the Covered Software under Section + 2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user + license agreements (excluding distributors and resellers) which have been + validly granted by You or Your distributors under this License prior to + termination shall survive termination. + +6. Disclaimer of Warranty + + Covered Software is provided under this License on an "as is" basis, + without warranty of any kind, either expressed, implied, or statutory, + including, without limitation, warranties that the Covered Software is free + of defects, merchantable, fit for a particular purpose or non-infringing. + The entire risk as to the quality and performance of the Covered Software + is with You. Should any Covered Software prove defective in any respect, + You (not any Contributor) assume the cost of any necessary servicing, + repair, or correction. This disclaimer of warranty constitutes an essential + part of this License. No use of any Covered Software is authorized under + this License except under this disclaimer. + +7. Limitation of Liability + + Under no circumstances and under no legal theory, whether tort (including + negligence), contract, or otherwise, shall any Contributor, or anyone who + distributes Covered Software as permitted above, be liable to You for any + direct, indirect, special, incidental, or consequential damages of any + character including, without limitation, damages for lost profits, loss of + goodwill, work stoppage, computer failure or malfunction, or any and all + other commercial damages or losses, even if such party shall have been + informed of the possibility of such damages. This limitation of liability + shall not apply to liability for death or personal injury resulting from + such party's negligence to the extent applicable law prohibits such + limitation. Some jurisdictions do not allow the exclusion or limitation of + incidental or consequential damages, so this exclusion and limitation may + not apply to You. + +8. Litigation + + Any litigation relating to this License may be brought only in the courts + of a jurisdiction where the defendant maintains its principal place of + business and such litigation shall be governed by laws of that + jurisdiction, without reference to its conflict-of-law provisions. Nothing + in this Section shall prevent a party's ability to bring cross-claims or + counter-claims. + +9. Miscellaneous + + This License represents the complete agreement concerning the subject + matter hereof. If any provision of this License is held to be + unenforceable, such provision shall be reformed only to the extent + necessary to make it enforceable. Any law or regulation which provides that + the language of a contract shall be construed against the drafter shall not + be used to construe this License against a Contributor. + + +10. Versions of the License + +10.1. New Versions + + Mozilla Foundation is the license steward. Except as provided in Section + 10.3, no one other than the license steward has the right to modify or + publish new versions of this License. Each version will be given a + distinguishing version number. + +10.2. Effect of New Versions + + You may distribute the Covered Software under the terms of the version + of the License under which You originally received the Covered Software, + or under the terms of any subsequent version published by the license + steward. + +10.3. Modified Versions + + If you create software not governed by this License, and you want to + create a new license for such software, you may create and use a + modified version of this License if you rename the license and remove + any references to the name of the license steward (except to note that + such modified license differs from this License). + +10.4.
