5.    Governing Law. The provisions of Sections 10.1 of the NPA are hereby incorporated by reference as if fully set forth herein.

6.    Counterparts. This Amendment may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.
