Item 5.07. Submission of Matters to a Vote of Security Holders.

On November 30, 2011, the Nalco Holding Company (“Nalco”) held a special meeting of its stockholders in connection with the Agreement and Plan of Merger dated as of July 19, 2011 (the “Merger Agreement”) by and among, Ecolab Inc., a Delaware corporation (“Ecolab”), Sustainability Partners Corporation, a Delaware corporation and wholly owned subsidiary of Ecolab (“Merger Sub”), and the Company, pursuant to which Nalco will merge with and into Merger Sub, with Merger Sub surviving as a wholly owned subsidiary of Ecolab (the “Merger”). At the special meeting, the following proposals were submitted to a vote of stockholders: (i) to adopt the Merger Agreement (the “Merger Proposal”), (ii) to approve, on a non-binding advisory basis, the compensation that may be come payable to the Company’s named executive officers in connection with the completion of the transactions in the Merger (the “Compensation Proposal”) and (iii) to approve an adjournment of the Company’s special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes to adopt the Merger Agreement (the “Adjournment Proposal”).

Each of the foregoing proposals is described in detail in the definitive proxy statement filed by Nalco with the SEC on October 28, 2011.

For each of the foregoing proposals, a quorum was present for the purpose of the vote. The Company’s stockholders approved each of the Merger Proposal and the Compensation Proposal. The following is a summary of the voting results for each proposal:

Merger Proposal


FOR	AGAINST	ABSTAIN	BROKER NON-VOTES
102,398,790	96,414	9,281	0

Compensation Proposal


FOR	AGAINST	ABSTAIN	BROKER NON-VOTES
94,390,651	7,056,183	1,057,651	0

As there were sufficient votes to approve the Merger Proposal, adjournment of the special meeting of its stockholders to solicit additional proxies was unnecessary and the Adjournment Proposal was not submitted to the Company’s stockholders for approval at the special meeting.

A copy of the press release announcing the outcome of the stockholder vote is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

Cautionary Statements Regarding Forward-Looking Information

This communication contains certain statements relating to future events and our intentions, beliefs, expectations and predictions for the future which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. Words or phrases such as “will likely result,” “are expected to,” “will continue,” “is anticipated,” “we believe,” “we expect,” “estimate,” “project,” “may,” “will,” “intend,” “plan,” “believe,” “target,” “forecast” (including the negative or variations thereof) or similar terminology used in connection with any discussion of future plans, actions or events generally identify forward-looking statements. These forward-looking statements include, but are not limited to, statements regarding benefits of the merger, integration plans and expected synergies, the expected timing of completion of the merger, and anticipated future financial and operating performance and results, including estimates for growth. These statements are based on the current expectations of management of Nalco and Ecolab, as applicable. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this communication. These risks and uncertainties include (i) the risk that the stockholders of Nalco may not adopt the merger agreement, (ii) the risk that the stockholders of Ecolab may not approve the issuance of Ecolab common stock to Nalco stockholders in the merger, (iii) the risk that the companies may be unable to obtain regulatory approvals required for the merger, or that required regulatory approvals may delay the merger or result in the imposition of conditions that could have a material adverse effect on the combined company or cause the companies to abandon the merger, (iv) the risk that the conditions to the closing of the merger may not be satisfied, (v) the risk that a material adverse change, event or occurrence may affect Nalco or Ecolab prior to the closing of the merger and may delay the merger or cause the companies to abandon the merger, (vi) the risk that an unsolicited offer by another company to acquire shares or assets of Nalco or Ecolab could interfere with or prevent the merger, (vii) problems that may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected, (viii) the possibility that the merger may involve unexpected costs, unexpected liabilities or unexpected delays, (ix) the risk that the credit ratings of the combined company or its subsidiaries may be different from what the companies currently expect, (x) the risk that the businesses of the companies may suffer as a result of uncertainty surrounding the merger and (xi) the risk that disruptions from the transaction will harm relationships with customers, employees and suppliers.

Other unknown or unpredictable factors could also have material adverse effects on future results, performance or achievements of Nalco, Ecolab and the combined company. For a further discussion of these and other risks and uncertainties applicable to the respective businesses of Nalco and Ecolab, see the Annual Reports on Form 10-K of Nalco and Ecolab for the fiscal year ended December 31, 2010 and the companies’ other public filings with the Securities and Exchange Commission (the “SEC”). These risks, as well as other risks associated with the merger, are more fully discussed in the joint proxy statement/prospectus included in the Registration Statement on Form S-4 that Ecolab has filed with the SEC in connection with the merger, which was declared effective by the SEC on October 28, 2011. On or about October 31, 2011, Nalco and Ecolab began mailing the definitive joint proxy statement/prospectus to stockholders of record as of the close of business on October 11, 2011. In light of these risks, uncertainties, assumptions and factors, the forward-looking events discussed in this communication may not occur. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this communication. Neither Nalco nor Ecolab undertakes, and each of them expressly disclaims, any duty to update any forward-looking statement whether as a result of new information, future events or changes in their respective expectations, except as required by law.
