SEPARATION AGREEMENT

This Separation Agreement is made this 30th day of June, 2007 between Nalco Company, for itself and on behalf of its direct or indirect affiliates, parents, subsidiaries  and predecessors (collectively the Company or Nalco) and William J. Roe (Mr. Roe).

Recitals

Mr. Roes current position with the Company will end on June 30, 2007.

Mr. Roe entered into a Severance Agreement with the Company with effective date of January 1, 2004 (the Severance Agreement).

Mr. Roe entered into a Death Benefit Agreement with the Company  (then Nalco Chemical Company) (the Death Benefit Agreement).

Mr. Roe entered into a Management Members Agreement with Nalco LLC, an indirect parent of Nalco, on or about June 30, 2004, pursuant to which Mr. Roe was given the opportunity to invest in certain equity ownership units in Nalco LLC (the Management Members Agreement).

Mr. Roe signed a consent permitting certain acceleration rights for the C and D Units on December 13, 2006 (the Consent Memorandum).

Under the Severance Agreement, any severance payments would be paid to Mr. Roe over the period from the date his employment ends to the date Mr. Roe becomes age 55, permitting Mr. Roe to elect retirement on the first day of the month following becoming age 55 (in December 2008).

As there are no severance payment obligations, the Company agrees that Mr. Roe will continue to vest in the B Units under the 2004 Nalco LLC Plan for the years 2007 and 2008 and he shall otherwise continue receiving medical and dental benefits as an active employee until he reaches age 55 in December 2008, permitting Mr. Roe to elect retirement on January 1, 2009.

Accordingly, Mr. Roe and Nalco agree as follows:

Mr. Roe does not waive and release any claims under the Death Benefit Agreement.

Mr. Roe will also provide a detailed statement of all business expenses that Mr. Roe claims he incurred for Nalcos business purposes that have not been reimbursed.

Mr. Roe agrees to return all Nalco property to Nalco promptly upon request.

5



---





possession in the course of the performance of his services under this Agreement, shall be the exclusive property of Company and shall be delivered to Company and not retained by Mr. Roe (including, without limitations, any copies thereof) upon termination of this Agreement for any reason whatsoever.

Mr. Roe will communicate and disclose in writing to the Company all inventions, discoveries, improvements, machines, devices, designs, processes, products, software, treatments, formulae, mixtures and/or compounds whether patentable or not as well as patents and patent applications made, conceived, developed or acquired by Mr. Roe or under which Mr. Roe acquired the right to grant licenses or become licensed, whether alone or jointly with others, during his employment with the Company (all collectively referred to as Inventions).

any matters pertaining to, applicable to, or useful in connection with, the business of the Company shall be deemed to have been made or conceived or developed by Mr. Roe during his employment with the Company.

Mr. Roe acknowledges that a breach of his covenants contained herein may cause irreparable damage to the Company (its subsidiaries and affiliates), the exact amount of which will be difficult to ascertain, that the remedies at law for any such breach will be inadequate and that the payments and other benefits, in this Separation Agreement and the amendment to the Management Members Agreement, are additional consideration for the covenants contained herein. Accordingly, Mr. Roe agrees that if he breaches any of the covenants contained herein, in addition to any other remedy which may be available at law or in equity, the Company shall be entitled to specific performance and injunctive relief. In addition, the breach of any of the covenants contained herein shall entitle the Company to permanently withhold, and, if applicable, to recover from Mr. Roe any payments,
benefits, or other entitlements, of any type owed by the Company to Mr. Roe under the Severance Agreement, the Consent Memorandum, this Separation Agreement, any other agreement or plan irrespective of whether the covenants in this Separation Agreement or the Severance Agreement are deemed enforceable by a court. The Company and Mr. Roe further acknowledge that the time, scope, geographic area and other provisions herein have been specifically negotiated by sophisticated commercial parties and agree that all such provisions are reasonable under the circumstances of the activities contemplated by this Agreement. In the event that the covenants herein shall be determined by any court of competent jurisdiction to be unenforceable by reason of their extending for too great a period of time or over too great a geographical area or by reason of their being too extensive in any other respect, they shall be interpreted to extend only over the maximum period of time for which they
may be enforceable and/or over the maximum geographical area as to which they may be enforceable and/or to the maximum extent in all other respects as to which they may be enforceable, all as determined by such court in such action.

Mr. Roe. The Company agrees to reimburse Mr. Roe, on an after-tax basis, for all expenses including pre-approved legal expenses, actually incurred in connection with his provision of testimony or assistance.

Mr. Roe will not make statements or representations, or otherwise communicate, directly or indirectly, in writing, orally, or otherwise, or take any action which may, directly or indirectly, disparage the Company, its subsidiaries and affiliates or its or their respective officers, directors, employees, advisors, businesses or reputations. The Company agrees that it shall advise the members of the Board of Directors and its senior officers not to disparage Mr. Roe and the Company shall use its reasonable business efforts to prevent them from doing so; provided, however,the Companys obligations to Mr. Roe in the immediately preceding sentence shall not apply to any oral, written or electronic statements, representations or other communications made internally at the Company by any
member of the Board of Directors or any of the Companys senior officers if such oral, written or electronic statements, representations or other communications are made by any of the foregoing individuals in the course of such individuals duties, responsibilities or obligations to the Company.
