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.
