Explanation of Responses:

1. The Reporting Person holds 4,500,000 class B units, 4,500,000 class C units and 3,000,000 class D units of Nalco LLC (the direct parent company of Nalco Holding Company). The Reporting Person has the right to transfer his Nalco LLC class B, class C and class D units that have vested, in exchange for shares of Nalco Holding Company common stock owned by Nalco LLC. Class B units, class C units and class D units will vest for continuing employees at certain dates and are subject to earlier vesting in some circumstances based on reaching certain performance requirements as described in the Management Members Agreements, which are filed as Exhibits 10.30 to 10.39 to the Registration Statement on Form S-1 of Nalco Holding Company (the "Management Members Agreements") (File No. 333-118583).

2. These rights to exchange Nalco LLC units for Nalco Holding Company common stock are exercisable following the day after the date on which the class B, class C and class D units vest. Class B units will vest in five equal annual installments on each December 31, beginning on December 31, 2004, subject to certain restrictions.

3. 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 Agreements.

4. 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.

5. Upon the exercise of these rights, Nalco LLC is required to purchase vested B units, vested C units and vested D units, at a purchase price equal to their Fair Market Value by delivering a number of shares of Nalco Holding Company common stock determined by dividing (A) the aggregate purchase price of the units being sold by such Reporting Person by (B) the arithmetic mean of the high and low prices per share as reported on such date on the New York Stock Exchange as of the close of trading on the trading day immediately prior to the delivery thereof to the Reporting Person.
