SECTION 6. Governing Law; Arbitration. This Amendment shall be governed by, construed under and enforced in accordance with the laws of the Commonwealth of Virginia without giving effect to its conflict of laws principles.

SECTION 7. Section Titles. The section titles contained in this Amendment are and shall be without substance, meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto.
