This Amendment No. 6 (this "Amendment") amends and supplements the Schedule 13D filed on December 20, 1989, as previously amended (the "Schedule 13D"), of Henkel KGaA ("KGaA") and HC Investments, Inc. ("HCI"), with respect to the Common Stock, par value $1.00 per share ("Common Stock"), of Ecolab Inc. ("Ecolab" or the "Company"). All capitalized terms used in this Amendment and not otherwise defined herein have the meanings ascribed to such terms in the Schedule 13D. Item 2. Identity and Background. Annex I to the Schedule 13D is amended and restated as attached to this Amendment to reflect the names, addresses, occupations and citizenship of the current executive officers, directors and controlling persons of HCI and KGaA. None of KGaA, HCI or, to the best knowledge of KGaA and HCI, any of the persons listed on Annex I hereto has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration. KGaA acquired 2,500,000 shares of Common Stock in open market purchases beginning on October 2, 2001, for an aggregate amount equal to approximately $89.4 million. The funds used for such purchases came from KGaA's general corporate resources. Item 4. Purpose of Transaction. As previously described in the Schedule 13D, Henkel and Ecolab have entered into a series of agreements and consummated a series of transactions through which they established and have conducted a long-term cooperative business relationship. Henkel's primary purpose for these agreements and transactions was for it to become and remain a long-term significant minority investor in Ecolab. As previously described in the Schedule 13D, on December 7, 2000, Henkel and Ecolab entered into the Master Agreement relating to the proposed sale by Henkel of its interests in the Joint Venture to Ecolab (the "Proposed Sale"). On September 28, 2001, Henkel and Ecolab announced that it is now anticipated that the Proposed Sale will be consummated on November 30, 2001. When the Proposed Sale is consummated, the business relationship between Henkel and Ecolab will be changed, and Henkel's primary relationship with Ecolab will be that of a significant minority stockholder. Consistent with that expectation, KGaA acquired the shares of Common Stock to which this Amendment relates in order to expand and strengthen its minority investment in, and to strengthen Henkel's long-term relationship with, Ecolab. As previously described in the Schedule 13D, under the Existing Stockholder's Agreement, Henkel may acquire shares of Common Stock so long as the acquisition does not cause Henkel to beneficially own more than 30% of the outstanding Common Stock, which percentage will be increased under the Proposed Amended Stockholder's Agreement to 35% upon consummation of the Proposed Sale. As previously described in the Schedule 13D, upon consummation of the Proposed Sale, Henkel will receive the purchase price in either cash in Euro or additional shares of Common Stock, at the election of Henkel, in an amount to be determined based on the earnings of the Joint Venture in fiscal years 2000 and 2001 pursuant to a formula in the Master Agreement. On September 28, 2001, Henkel and Ecolab announced that it is now anticipated that the purchase price will range between approximately EUR 480 million to EUR 510 million. As previously described in the Schedule 13D, if Henkel elects to take Common Stock, the number of shares to be issued will be calculated using a per share value of $41.0625, subject to a maximum of 13,203,672 and a minimum of 9,270,664 shares being issued. Henkel has not yet determined whether it will elect to take cash or stock in connection with the Proposed Sale. The number of shares of Common Stock purchased in the open market transactions described above is such that Henkel would not own more than the 35% permitted under the Proposed Amended Stockholder's Agreement if Henkel elects to receive the purchase price in the form of Common Stock. In accordance with the Existing Stockholder's Agreement, Ulrich Lehner, Stefan Hamelmann and Hugo Uyterhoeven were nominated for election to Ecolab's Board of Directors (the "Ecolab Board") at Ecolab's most recent annual meeting of stockholders and currently serve as members of the Ecolab Board. Henkel intends to continue to review its investment in Common Stock from time to time and, depending upon certain factors, including without limitation the financial performance of Ecolab, the availability and price of shares of Common Stock on the open market, Henkel's overall relationship with Ecolab and the status of the Joint Venture and the Proposed Sale, and other general market and investment conditions, Henkel may determine to acquire through open market purchases or otherwise additional shares of Common Stock, or, based upon such factors, to sell shares of Common Stock, from time to time, in each case to the extent permitted under the Existing Stockholder's Agreement (or the Proposed Amended Stockholder's Agreement, as applicable) and applicable law. Except as set forth herein, Henkel has no current plans or proposals that relate to or would result in any of the actions or events enumerated in clauses (a) through (j) of Item 4 of Schedule 13D, as promulgated by the Securities and Exchange Commission. Item 5. Interest in Securities of the Issuer. (a)-(b) At the date hereof, in the aggregate, the 34,738,176 shares of Common Stock owned by HCI and KGaA represent approximately 27.2% of the 127,915,535 shares of Common Stock reported by Ecolab in its Quarterly Report on Form 10-Q to be outstanding as of July 31, 2001. Of that total, HCI beneficially owns 14,666,664 shares of Common Stock (approximately 11.5% of such total). HCI and, by virtue of its indirect control of HCI, KGaA share the power to vote and the power to dispose of these shares of Common Stock (subject to the provisions of the Existing Stockholder's Agreements). KGaA directly and beneficially owns the remaining 20,071,512 shares of Common Stock (approximately 15.7% of such total). KGaA has the sole power to vote and the sole power to dispose of those shares of Common Stock (subject to the provisions of the Existing Stockholder's Agreements). At the date hereof, to the best knowledge of HCI and KGaA, Ulrich Lehner (the President and Chief Executive Officer of KGaA and a member of the Ecolab Board) is the beneficial owner (with sole voting and dispositive power) of 4,171 shares of Common Stock (including 3,800 shares that could be purchased under stock options granted by Ecolab and 371 shares represented by stock units granted by Ecolab under its Non-Employee Director Deferred Compensation Plan). At the date hereof, to the best knowledge of HCI and KGaA, Stefan Hamelmann (a member of the Shareholders' Committee of KGaA and a member of the Ecolab Board) is the beneficial owner (with sole voting and dispositive power) of 4,171 shares of Common Stock (including 3,800 shares that could be purchased under stock options granted by Ecolab and 371 shares represented by stock units granted by Ecolab under its Non-Employee Director Deferred Compensation Plan). At the date hereof, to the best knowledge of HCI and KGaA, Albrecht Woeste (the Chairman of the Supervisory Board of KGaA and a former member of the Ecolab Board) is the beneficial owner (with sole voting and dispositive power) of 43,512 shares of Common Stock (including 24,000 shares that could be purchased under stock options granted by Ecolab). At the date hereof, to the best knowledge of HCI and KGaA, Roland Schulz (a member of the Board of Management of KGaA and a former member of the Ecolab Board) is the beneficial owner (with sole voting and dispositive power) of 38,102 shares of Common Stock (including 22,400 shares that could be purchased under stock options granted by Ecolab). HCI and KGaA disclaim beneficial ownership of any of the shares beneficially owned by Ulrich Lehner, Stefan Hamelmann, Albrecht Woeste and Roland Schulz. At the date hereof, except as stated herein, neither HCI nor KGaA nor, to the best of their knowledge, Henkel of America, Inc., Henkel Corporation or any of the persons listed on Annex I hereto beneficially owns any shares of Common Stock (other than shares of Common Stock beneficially owned by HCI or KGaA of which one or more of such other persons may be deemed to have beneficial ownership pursuant to Rule 13d-3 of the Exchange Act). (c) Certain information with respect to each transaction in the Common Stock since December 14, 2000 (the date of Amendment No. 5 to the Schedule 13D) is set forth in Exhibit 20 hereto. Except as set forth herein, no transactions in shares of Common Stock were effected during the past 60 days by HCI or KGaA, or, to the best of their knowledge, by Henkel of America, Inc., Henkel Corporation or any of the other persons listed on Annex I hereto.
