Section 6.11 Severability. To the fullest extent permitted by law, any term or provision of this Agreement, or the application thereof, that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is illegal, void, invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any illegal, void, invalid or unenforceable term or provision with a term or provision that is legal, valid and enforceable and that comes closest to expressing the intention of the illegal, void, invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. To the fullest extent permitted by law, in the event such court does not exercise the power granted to it in the prior sentence, the parties hereto shall replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the original economic, business and other purposes of such invalid or unenforceable term as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.
