AMENDMENT NO.1 TO REGISTRATION RIGHTS
AGREEMENT

AMENDMENT NO. 1 TO REGISTRATION RIGHTS
AGREEMENT (the
‘‘Amendment’’), dated as of
December  30,  2005, by and among Nalco Holding Company, a
Delaware corporation (the
‘‘Company’’), Nalco LLC, a
Delaware limited liability company (‘‘Nalco
LLC’’), the Sponsor Members, the Management
Members and the other Holders, to the Registration Rights Agreement (as
amended, supplemented or otherwise modified, the
‘‘Agreement’’), dated as of
November  16,
2004.

RECITALS

WHEREAS, the
Company, Nalco LLC, the Sponsor Members and the Management Members have
heretofore executed the Agreement.

WHEREAS, one of the
purposes of the Agreement was to provide the parties listed on Schedule
A hereto (the ‘‘Released Management
Holders’’) with certain registration rights in
order to enable them to sell registered shares of the Company’s
common stock.

WHEREAS, the Agreement was intended, in
part, to enable Management Members to sell shares of the
Company’s common stock received in exchange for units of Nalco
LLC on a registered basis by granting them certain incidental
(‘‘piggyback’’) registration rights in
connection with registered offerings of the Company’s common
stock by Nalco LLC or the Sponsor Members.

WHEREAS, the
Agreement subjects Management Members to certain obligations, including
lock-up provisions, pursuant to which such Management Members may be
prohibited from selling their shares of the Company’s common
stock for up to 14 days prior to and up to 180 days following such
offerings.

WHEREAS, Company has filed a shelf
registration statement on Form S-3 to register shares of the
Company’s common stock held by the Released Management Holders,
along with any prospectus supplements or post-effective amendments, as
applicable, in order to facilitate the disposition of the Released
Management Holders’ Registrable Shares.

WHEREAS,
the parties hereto have determined that the shelf registration
statement will satisfy the purpose of enabling the Released Management
Holders to sell their Registrable Shares on a registered basis, and
have consequently agreed to release the Released Management Holders
from the Agreement so that they would no longer be entitled to rights
or subject to restrictions thereunder.

NOW THEREFORE, in
consideration of the agreements set forth herein, and for other good
and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, and intending to be legally bound hereby, pursuant
to Section 6(b) of the Agreement, the parties hereto agree that
effective as of the date hereof, the Released Management Holders will
no longer be deemed a party to the Agreement and will not be entitled
to any rights or subject to any obligations under the
Agreement.

Except as expressly amended hereby, the Agreement is
in all respects ratified and confirmed and all the terms, conditions
and provisions thereof shall remain in full force and effect.

Capitalized terms used herein without definition have the
meanings assigned to them in the
Agreement.

                                 FIRST AMENDMENT
                                       TO
                       LIMITED LIABILITY COMPANY AGREEMENT

      This First Amendment (the "Amendment") to the Limited Liability Company
Agreement of Nalco LLC (the "Company"), dated as of May 17, 2004 (the
"Agreement"), is made and entered into as of December 30, 2005 by and among the
Sponsor Members named in the Agreement. Capitalized terms not otherwise defined
herein shall have the meanings ascribed to such terms in the Agreement.

      WHEREAS, pursuant to Section 3.14 of the Agreement, in the event that the
Company ceases to qualify as an "operating company" (as defined in 29 C.F.R. ss.
2510.3-101(c)), then the Company and each Member will cooperate in good faith to
take all reasonable action necessary to provide that the investment (or at least
51% of the investment valued at cost) of each Member that qualifies as a
"venture capital operating company" (as defined in 29 C.F.R. ss. 2510.3-101(d))
(a "VCOC Member") shall continue to qualify as a "venture capital investment"
(as defined in 29 C.F.R. ss. 2510.3-101(d));

      WHEREAS, upon the completion of the sale of shares of common stock of
Nalco Holding Company (the "Common Shares") by the Company on the date hereof,
the Company shall cease to qualify as an "operating company";

      WHEREAS, in connection with such event, the Company, pursuant to the
stockholders agreement dated as of November 16, 2004 by and among the Company,
the Sponsor Members and Nalco Holding Company, is obligated to distribute to
each VCOC Member, through a redemption of its Class A Units, the Common Shares
beneficially owned by such VCOC Member, as determined by the Board and the
pricing committee of the Board (such redemption, the "VCOC Redemption");

      WHEREAS, in connection with the VCOC Redemption and in accordance with
Section 3.14 of the Agreement, the parties desire to amend certain provisions of
the agreement to reflect the fact that the VCOC Members will hold Common Shares
directly and will no longer hold Class A Units; and

      WHEREAS, pursuant to Section 13.09 of thereof, the Agreement may be
amended by the agreement of two of the Investor Groups;

      NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein and in the Agreement, and in consideration of other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending to be legally bound, hereby agree to
amend the Agreement as follows:

      1.    Ownership Thresholds. With respect to any provision of the
Agreement which provides for the determination of an Investor Group's beneficial
ownership percentage of Class

A Units relative to such Investor Group's Initial Equity Stake, such Investor
Group's number of "Class A Units" shall be deemed to include both (a) the number
of Class A Units that such Investor Group owns and (b)a number of Class A Units
having a value equivalent to that of the number of Common Shares owned by such
Investor Group (calculated based on the price per Class A Unit most recently
determined by the Board or the pricing committee of the Board).

      2.    Entire Agreement. The Agreement, this Amendment, the Management
Members Agreement and the Registration Rights Agreement set forth the entire
understanding and agreement of the parties hereto and supersede any and all
other understandings, term sheets, negotiations or agreements between the
parties hereto relating to the subject matter of this Agreement and the
Registration Rights Agreement. In the event of any conflict between a provision
of this Agreement and a provision of the Management Members Agreement, the
relevant provision of this Agreement, as amended, shall be deemed to control and
shall supersede the conflicting provision of the Management Members Agreement.

      3.    Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH,
AND GOVERNED BY, THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO CONFLICTS
OF LAWS PRINCIPLES WHICH WOULD RESULT IN THE APPLICATION OF THE LAWS OF ANOTHER
JURISDICTION.

      4.    Severability. In the event that any one or more of the provisions
contained in this Agreement shall for any reason be held to be invalid, illegal
or unenforceable, the same shall not affect any other provision of this
Agreement, but this Agreement shall be construed in a manner which, as nearly as
possible, reflects the original intent of the parties.

      5.    Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed an original, and all of which together shall
constitute a single agreement.

      6.    Full Force and Effect of Agreement. The Agreement, as modified by
this Amendment, and as this Amendment is made a part thereof, shall remain in
full force and effect.

              [The remainder of this page intentionally left blank]

      IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed as of the date first written above.
