5. Class B units will vest in five equal annual investments on each December 31, beginning on December 31, 2004, subject to certain restrictions. Class C units will vest on the 8th anniversary of the date on which they are sold to a manager, subject to certain restrictions, but may vest earlier over the next five years, beginning on December 31, 2004, if Nalco Holding Company meets certain EBITDA targets. Class D units will vest on the 10th anniversary of the date on which they are sold to a manager, subject to certain restrictions, but may vest earlier over the next five years, beginning on December 31, 2004, if Nalco Holding Company meets certain EBITDA targets. See the Management Members Agrements.

6. Subject to the exercise of a call right, for so long as certain termination events (see the Management Members Agreements) have not occurred with respect to the Reporting Person, there is no expiration of the right to exchange Nalco LLC units for Nalco Holding Company common stock.

7. Not applicable.

8. Following the reported transaction, the Reporting Person owns 99,000,000 class B units, 99,000,000 class C units and 66,000,000 class D units of Nalco LLC, which have the exchange rights described herein.
