NOW, THEREFORE, for and in consideration of good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto

eighty seven thousand five hundred dollars ($187,500) per QUARTER, hereafter,
“P&G QUARTERLY PAYMENTS” from the PREVIOUSLY PAID QUARTERLY PAYMENTS.
4.2.1. Upon the conclusion of ten (10) QUARTERS after January 1, 2009, the
exclusive license granted to P&G by BIOLASE under section 2.1 shall revert to a
non-exclusive license unless P&G pays BIOLASE a QUARTERLY payment of one hundred
eighty seven thousand five hundred dollars ($187,500). ”
