* whether in tort (including negligence), contract, or otherwise,

* unless required by applicable law (such as deliberate and grossly

* negligent acts) or agreed to in writing, shall any Contributor be

* liable to You for damages, including any direct, indirect, special,

* incidental, or consequential damages of any character arising as a

* result of this License or out of the use or inability to use the

* Work (including but not limited to damages for loss of goodwill,

* work stoppage, computer failure or malfunction, or any and all

* other commercial damages or losses), even if such Contributor

* has been advised of the possibility of such damages.

* the Work or Derivative Works thereof, You may choose to offer,

* and charge a fee for, acceptance of support, warranty, indemnity,

* or other liability obligations and/or rights consistent with this

* License. However, in accepting such obligations, You may act only
