On November 10, 2008, Ecolab Inc. ("Ecolab" or the "Company") and Henkel AG & Co. KGaA ("Henkel," and together with its subsidiary Henkel Corporation, the "Selling Stockholders") entered into an amendment (the "Amendment") to the stockholder's agreement (the "Stockholder's Agreement") that governs Henkel's equity ownership in the Company. Pursuant to the Amendment, the Company agreed to meet with potential investors in connection with up to two registered public offerings of Ecolab common stock by the Selling Stockholders. Additionally, among other things, the Company agreed to permit sales to certain persons that, together with such person's affiliates or any group of which such person may be a member, would beneficially own up to five percent of Ecolab's outstanding stock and waive its right of first refusal in connection with certain transfers by Henkel.

Also, on November 10, 2008, the Company entered into a stock purchase agreement (the "Stock Purchase Agreement") with the Selling Stockholders, pursuant to which the Company agreed to purchase from the Selling Stockholders, following the completion of the first registered public offering, shares of Ecolab common stock for consideration of, at the Company's discretion, between $300 million and $500 million. The number of shares that Ecolab will acquire for a given level of consideration will be determined pursuant to a formula set forth in the Stock Purchase Agreement. The Company may also purchase in excess of $500 million of shares from the Selling Stockholders at the price per share equal to the price to the public, less underwriting discounts and commissions. The Selling Stockholders will only sell shares in the first offering if at least 43,700,000 shares are sold, and if the offering is not consummated by April 30, 2009, the Company will have no obligation to purchase any shares from the Selling Stockholders in connection with the first offering, but Ecolab will remain obligated to purchase shares of common stock in connection with a potential second offering by the Selling Stockholders, subject to the same terms and conditions as described for the first offering.

Ecolab intends to finance the stock purchase with available cash and the proceeds of an issuance of commercial paper under its existing commercial paper program and may also utilize committed bank lines.

The foregoing descriptions of the Amendment to the Stockholder's Agreement and the Stock Purchase Agreement do not purport to be complete and are qualified in their entirety by reference to the full text thereof, copies of which are attached as Exhibits 4.1 and 10.1, respectively, and incorporated herein by reference.
