            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

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

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

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

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.

      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.
