3. This Amendment shall be construed and enforced in accordance with the domestic, internal law, but not the law of conflict of laws, of the State of New York.

4.This Amendment may be executed in any number of counterparts each of which shall be deemed an original and all of which, taken together, shall constitute a single original document.
