internal laws of the State of California to the rights and duties of the
parties. Should any provision of this Amendment Agreement be determined by a
court of law to be illegal or unenforceable, such provision shall be enforced to
the fullest extent allowed by law and the other provisions shall nevertheless
remain effective and shall remain enforceable.

8.This Amendment Agreement shall be binding upon InterDent and its successors
and assigns (if any), and Holder and his or her successors and assigns (if any).
