2. License Grants and Conditions

2.1. Grants
Each Contributor hereby grants You a world-wide,
royalty-free, non-exclusive license:
  a. under intellectual property rights (other than patent
     or trademark) Licensable by such Contributor to use, 
     reproduce, make available, modify, display, perform, 
     distribute, and otherwise exploit its Contributions, 
     either on an unmodified basis, with Modifications, or 
     as part of a Larger Work; and
  b. under Patent Claims of such Contributor to make, use, 
  sell, offer for sale, have made, import, and otherwise 
  transfer either its Contributions or its Contributor 
  Version.

2.2. Effective Date
The licenses granted in Section 2.1 with respect to any 
Contribution become effective for each Contribution on the 
date the Contributor first distributes such Contribution. 

2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights
granted under this License. No additional rights or 
licenses will be implied from the distribution or licensing
of Covered Software under this License. Notwithstanding
Section 2.1(b) above, no patent license is granted by a
Contributor:
  a. for any code that a Contributor has removed from 
     Covered Software; or
  b. for infringements caused by: (i) Your and any other
     third party's modifications of Covered Software, or 
     (ii) the combination of its Contributions with other
     software (except as part of its Contributor Version);
     or
  c. under Patent Claims infringed by Covered Software in 
     the absence of its Contributions.
This License does not grant any rights in the trademarks,
service marks, or logos of any Contributor (except as may
be necessary to comply with the notice requirements in 
Section 3.4). 

2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your
choice to distribute the Covered Software under a 
subsequent version of this License (see Section 10.2) or
under the terms of a Secondary License (if permitted under
the terms of Section 3.3). 

2.5. Representation
Each Contributor represents that the Contributor believes
its Contributions are its original creation(s) or it has
sufficient rights to grant the rights to its Contributions
conveyed by this License.

2.6. Fair Use
This License is not intended to limit any rights You have
under applicable copyright doctrines of fair use, fair
dealing, or other equivalents.

2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the
licenses granted in Section 2.1.


3. Responsibilities 

3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form,
including any Modifications that You create or to which You
contribute, must be under the terms of this License. You
must inform recipients that the Source Code Form of the
Covered Software is governed by the terms of this License,
and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the
Source Code Form.

3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
  a. such Covered Software must also be made available in
     Source Code Form, as described in Section 3.1, and You
     must inform recipients of the Executable Form how they
     can obtain a copy of such Source Code Form by
     reasonable means in a timely manner, at a charge no
     more than the cost of distribution to the recipient;
     and
  b. You may distribute such Executable Form under the 
     terms of this License, or sublicense it under 
     different terms, provided that the license for the 
     Executable Form does not attempt to limit or alter the
     recipients' rights in the Source Code Form under this
     License.

3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of
Your choice, provided that You also comply with the
requirements of this License for the Covered Software. If
the Larger Work is a combination of Covered Software with a
work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary
Licenses, this License permits You to additionally 
distribute such Covered Software under the terms of such
Secondary License(s), so that the recipient of the Larger
Work may, at their option, further distribute the Covered
Software under the terms of either this License or such
Secondary License(s).

3.4. Notices
You may not remove or alter the substance of any license
notices (including copyright notices, patent notices,
disclaimers of warranty, or limitations of liability)
contained within the Source Code Form of the Covered
Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies. 

3.5. Application of Additional Terms 
You may choose to offer, and to charge a fee for, warranty,
support, indemnity or liability obligations to one or more
recipients of Covered Software. However, You may do so only
on Your own behalf, and not on behalf of any Contributor.
You must make it absolutely clear that any such warranty,
support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every
Contributor for any liability incurred by such Contributor
as a result of warranty, support, indemnity or liability
terms You offer. You may include additional disclaimers of
warranty and limitations of liability specific to any
jurisdiction.

4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms
of this License with respect to some or all of the Covered
Software due to statute, judicial order, or regulation then
You must: (a) comply with the terms of this License to the
maximum extent possible; and (b) describe the limitations
and the code they affect. Such description must be placed
in a text file included with all distributions of the
Covered Software under this License. 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. Distributing Source Code Form that is Incompatible
   With Secondary Licenses
   If You choose to distribute Source Code Form that is
   Incompatible With Secondary Licenses under the terms of
   this version of the License, the notice described in 
   Exhibit B of this License must be attached.
