Consultant's consulting relationship with the Company; and

            The Company and Consultant agree that the terms and provisions of
this Agreement shall supersede any of terms and conditions that might have
existed between the parties.

            In consideration of the mutual covenants and promises contained
herein, the Company and Consultant, agree:

            1.    Consulting Relationship. Subject to the terms and conditions
set forth herein, the Company shall retain Consultant to perform the following

at all times be an independent contractor. Consultant is not an employee and
shall not be entitled to any benefits, medical insurance, worker' compensation
or compensation benefits that are available to employees of the Company either
by plan, agreement or policy, and the Company shall not withhold any taxes or
other amounts from the amounts paid hereunder or otherwise treat Consultant as
if he were an employee. Consultant's rights to payments and other amounts from
the Company shall be limited to those contractual rights provided in this
Agreement.

            2.    Performance. During the Term, Consultant will serve the
Company faithfully and to the best of his ability and will devote his full
business time, energy, experience and talents to the business of the Company,
provided that Consultant has pending part-time commitments (which will not
interrupt his performance of the Services) which he is permitted to complete on
or before October 31, 2004. At his option, Consultant, upon thirty (30) days
advance written notice to the Company may reduce his service level hereunder by
up to 50% (the "Reduced Services").

            3.    Term. Subject to: the extension for purposes of the Management
Equity Plan described in Section 4 below, the term of this Agreement shall begin
upon the Effective Date and shall initially continue for a period of no more
than two (2) years from such date (the "Term"). During the Term, Consultant may
terminate this Agreement at his will by providing fifteen (15) days notice to
the Company, and the Company may immediately terminate this Agreement by
providing notice to Consultant ("At Will Termination").

In the event of an At Will Termination, all obligations under this Agreement
shall end on such termination.

            4.    Management Equity Plan. (a) The Company has provided
Consultant with the following documents: (i) an offering memorandum describing
an opportunity to purchase certain units (the "A Units") in the Company's
current ultimate parent, Nalco LLC (the "Management Equity Plan"), (ii) a
Limited Liability Company Agreement for Nalco LLC, (iii) a Registration Rights
Agreement for Nalco LLC, (iv) a Management Members Agreement for A Units and (v)
a Subscription Agreement permitting Consultant the opportunity of purchasing
$200,000 of A Units pursuant to the Management Equity Plan and (vi) 2004 Unit
Plan (collectively the "Management Equity Plan Agreements"). Consultant may
purchase $200,000 in A Units subject to the Management Equity Plan, by executing
the Management Equity Plan Agreements, making the payment to Nalco LLC for
$200,000 and executing this Agreement (the "Consultant A Units"). (b) Consultant
acknowledges that the Management Equity Plan was initially created for employees
of the Company and that the Management Equity Plan Agreements refer to the
participants as employees of the Company, but that notwithstanding any such
references Consultant shall not be an employee of the Company or Nalco LLC and
shall not have any rights as an employee by reason of his participation in the
Management Equity Plan or his execution of the Management Equity Plan
Agreements. (c) In the event that Consultant elects Reduced Services pursuant to
Section 2 during the Term, the Company shall have the option to purchase from
Consultant a pro-rata percentage of the Consultant A Units at their then fair
market value (as determined pursuant to the Management Equity Plan) where such
pro-rata percentage equals the percentage reduction in Services elected by
Consultant. Further, in the event Consultant elects to terminate this Agreement
at his will during the Term, the Company shall have the option to purchase all
of the Consultant A Units at their then fair market value. (d) These call
options are in addition to the call options in the Management Equity Plan
Section

opportunity to receive a bonus from the Company in the event of certain
conditions, including an imposition of a certain tax on A Units and continued
service to the Company on January 1, 2007 (the "Contingent Bonus"). In the event
that the certain tax described in the Contingent Bonus is imposed upon
Consultant, the Company shall continue to pay Consultant $1 per month for the
period July 1, 2006, through and including January 1, 2007 (the "Interim
Period"), and this Agreement shall be extended during that Interim Period to
permit Consultant the opportunity to receive the Contingent Bonus on or about
January 1, 2007, provided that Consultant otherwise meets the terms and
conditions of the Contingent Bonus. During the Interim Period, Consultant shall
have no obligation to provide Services to the Company.

      target award of 45% of a base amount of $250,000 - for partial years, the

                         Attention: General Counsel

                  8.     General.

a.    Governing Law. The validity, interpretation, construction and performance
      of this Agreement shall be governed by the laws of the State of Illinois
      applicable to contracts executed and to be performed entirely within said
      State.

b.    Construction and Severability. If any provision of this Agreement shall be
      held invalid, illegal or unenforceable in any jurisdiction, the validity,
      legality and enforceability of the remaining provisions contained herein
      shall not in any way be affected or impaired, and the parties undertake to
      implement all efforts which are necessary, desirable and sufficient to
      amend, supplement or substitute all and any such invalid, illegal or
      unenforceable provisions with enforceable and valid provisions which would
      produce as nearly as may be possible the result previously intended by the
      parties without renegotiation of any material terms and conditions
      stipulated herein.

c.    Assignability. Consultant may not assign his interest in or delegate his
      duties under this Agreement. This Agreement is for the Services of
      Consultant, personally, and the Services to be rendered by him under this
      Agreement must be rendered by him and no other person. Consultant
      represents and warrants to the Company that Consultant has no contracts or
      agreements of any nature that Consultant has entered into with any other
      person, firm or corporation that contain any restraints on Consultant's
      ability to perform his obligations under this Agreement. This Agreement
      shall be binding upon and inure to the benefit of the Company and its
      successors and assigns.

d.    Compliance with Rules and Policies. Consultant shall perform all Services
      in all material respects in accordance with the applicable policies,
      procedures and rules established by the Company, including, but not
      limited to, the By-Laws of the Company and the Company's Code of Ethical
      Business Practices. In addition, Consultant, where applicable, shall
      comply in all material respects with all laws, rules and regulations that
      are generally applicable to the Company, and its employees, directors and
      officers.

e.    Arbitration. (1) The parties shall use their reasonable best efforts and
      good will to settle all disputes by amicable negotiations. The Company and
      Consultant agree that any dispute, controversy or claim arising out of,
      relating to or in connection with this Agreement, or the termination of
      this Agreement or the termination of Consultant's Services hereunder that
      is not amicably resolved by negotiation shall be finally settled by
      arbitration, under and in accordance with the Rules of Commercial
      Arbitration of the American Arbitration Association then in effect, as set
      forth below, in Chicago, Illinois, or such other place agreed to by the
      parties.

        (2) Any such arbitration shall be heard before a panel consisting of
            one (1) to three (3) arbitrators, each of whom shall be impartial.
            All arbitrators shall be appointed in the first instance by
            agreement between the parties. If the parties cannot agree upon a
            single arbitrator, each of the Company and Consultant shall be
            entitled to appoint one arbitrator. These two appointed arbitrators
            shall then appoint a third arbitrator by their mutual agreement.

        (3) The award of the arbitrator or panel of arbitrators shall be in
            writing and state the reasons upon which it is based. It may be made
            public only with the consent of the parties. Any monetary award
            shall be in U.S. dollars.

        (4) Each of the parties hereto accepts the exclusive jurisdiction of
            the arbitrator or panel of arbitrators appointed in accordance
            herewith. The award of the arbitrator or arbitral panel shall be
            final and binding on the parties, who undertake to carry it out
            without delay. Judgment on the award rendered by the arbitrator or
            arbitral panel may be entered in any court having jurisdiction
            thereof.

        (5) The arbitrator or panel of arbitrators may also award interim
            relief and grant specific performance. Notwithstanding the
            foregoing, each party reserves the right to apply to any court of
            competent jurisdiction for any provisional measure, including
            injunctive relief, to enforce the terms of this Agreement.

        (6) The Company and Consultant shall each pay fifty percent (50%) of
            all costs of the arbitrator or panel of arbitrators and of the
            American Arbitration Association. The arbitrator may award to the
            party prevailing on any matter or issue within the arbitration, his
            or its legal fees and disbursements (including the costs of the
            American Arbitration Association and the arbitrator) related to such
            matter or issue provided that the party is successful overall on a
            material portion of the arbitration, provided, however, the Company
            shall only be entitled to an award of legal fees and disbursements
            if the resolution of any such contest or dispute includes a finding
            that Consultant's claims in such contest or dispute were frivolous
            or brought in bad faith.

f.    Entire Agreement: Modification. This Agreement constitutes the entire
      agreement of the parties hereto with respect to the subject matter hereof,
      supersedes all prior agreements and undertakings, both written and oral,
      and may not be modified or amended in any way except in writing by the
      parties hereto.

g.    Survival. The covenants set forth in Section shall survive and shall
      continue to be binding upon the Consultant notwithstanding the termination
      of this Agreement for any reason whatsoever.

h.    Waiver. No waiver by either party hereto of any of the requirements
      imposed by this Agreement on, or any breach of any condition or provision
      of this Agreement to be performed by, the other party shall be deemed a
      waiver of a similar or dissimilar requirement, provision or condition of
      this Agreement at the same or any prior or subsequent time. Any such
      waiver shall be express and in writing, and there shall be no waiver by
      conduct.

i.    Counterparts. This Agreement may be executed in two or more counterparts,
      all of which taken together shall constitute one instrument.

            IN WITNESS WHEREOF, the parties hereto, intending to be
legally bound, have hereunto executed this Agreement as of the day and year
first written above.
