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


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


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


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.

such modified license differs from this License).
