(1) (1) The 32,465,221 shares of Nalco Holding Company's (the "Issuer") common stock reported as beneficially owned in the above table assumes the issuance of a dividend immediately prior to the consummation of the Issuer's initial public offering of 90,175,916 shares of the Issuer's common stock to Nalco LLC, and reflects an indirect beneficial ownership in the Issuer based on the membership interests in Nalco LLC held by Blackstone Capital Partners IV L.P., Blackstone Family Investment Partnership IV-A L.P. and Blackstone Capital Partners IV-A L.P. (collectively, the "Blackstone Funds").
(2) (2) Blackstone Management Associates IV L.L.C. ("BMA") is the general partner having voting and investment power over the shares of common stock held or controlled by each of the Blackstone Funds, which own in the aggregate approximately 36% of Nalco LLC. The balance of the membership interests in Nalco LLC are held by affiliates of the Goldman Sachs Group, Inc. and Apollo Management, L.P. (together with the Blackstone Funds, the "LLC Members"), as well as certain members of management of the Issuer. Because voting and dispositive decisions of Nalco LLC with respect to the common stock of the Issuer require the approval of at least two of the LLC Members, the Blackstone Funds disclaim beneficial ownership of the Issuer's securities held by Nalco LLC. Nonetheless, BMA, the Blackstone Funds and the other reporting persons identified herein are voluntarily reporting an indirect beneficial ownership in the Issuer's common stock, as reflected herein.
(3) (3) The Blackstone Funds, BMA, Messrs. Peter G. Peterson and Stephen A. Schwarzman (the founding members of BMA) disclaim beneficial ownership of all shares of the Issuer's common stock in excess of their pecuniary interest, if any, and this report shall not be deemed an admission that any such person or entity is the beneficial owner of, has any pecuniary interest in, such securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.
