not affect the validity or enforceability of the other terms or provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction and the remaining terms and
provisions shall remain in full force and effect, unless doing so would result in an interpretation of this Agreement which is manifestly unjust.

upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection
with this Agreement), will be construed in accordance with and governed by the laws of the State of New York without regard to principles of conflicts of laws. Any action against any party relating to the foregoing shall be brought in any federal or

 15. Counterparts. This Agreement may be executed in counterparts,

and delivering this Agreement in the presence of the other Party. No Party shall be bound until such time as all of the Parties have executed counterparts of this Agreement.
