4. Counterparts. This Amendment may be signed in counterparts with the same effect as if the signature on each counterpart were upon the same instrument. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, 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 or “.pdf” signature page were an original thereof.

5. Headings. The headings of Articles and Sections in this Amendment are provided for convenience only and will not affect its construction or interpretation.

6. Waiver. Neither any failure nor any delay by any party in exercising any right, power, or privilege under this Amendment or any of the documents referred to in this Amendment will operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege.

7. Severability. The invalidity or unenforceability of any provisions of this Amendment pursuant to any applicable law shall not affect the validity of the remaining provisions hereof, but this Amendment shall be construed as if not containing the provision held invalid or unenforceable in the jurisdiction in which so held, and the remaining provisions of this Amendment shall remain in full force and effect. If the Amendment may not be effectively construed as if not containing the provision held invalid or unenforceable, then the provision contained herein that is held invalid or unenforceable shall be reformed so that it meets such requirements as to make it valid or enforceable.

8. Governing Law. This Amendment shall be governed by and construed according to the laws of the State of Delaware, without regard to the conflict of laws provisions thereof. Any dispute arising under or in relation to this Amendment shall be resolved exclusively in the competent federal or state court sitting in the State of Delaware, and each of the parties hereby submits irrevocably to the jurisdiction of such court.
