shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need
not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid and binding obligation of the party executing (or on whose
behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof.

5.10Severability.If any provision of this Agreement is held to be invalid or unenforceable in any respect, the
validity and enforceability of the remaining terms and provisions of this Agreement shall not in any
way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefore, and upon so agreeing, shall incorporate such
