If any provision of this Agreement is found by a proper authority to be unenforceable, that provision to the extent it is found to be unenforceable or invalid will be severed and the remainder of the provision and this Agreement will continue in full force and effect. The Parties will use their best efforts to agree upon a valid and enforceable provision as a substitute for any invalid or unenforceable provision, taking in to account the Parties’ original intent of this Agreement.
