>4. Inability to Comply Due to Statute or Regulation.

>Your receipt of the notice.
>5.2. If You initiate litigation against any entity by asserting a patent

>counter-claims, and cross-claims) alleging that a Contributor Version
>directly or indirectly infringes any patent, then the rights granted to

>resulting from such party's negligence to the extent applicable law
>prohibits such limitation. Some jurisdictions do not allow the 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

>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

>such modified license differs from this License).
