Cautionary Statements Regarding Forward Looking Information.

Statements contained in this Current Report on Form 8-K, including statements concerning Ecolab’s restructuring plan, may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based on the current expectations of management of the Company. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this report. In particular, the ultimate results of any restructuring initiative depend on a number of factors, including the development of final plans, the impact of local regulatory requirements regarding employee terminations, the time necessary to develop and implement the restructuring initiatives and the level of success achieved through such actions in improving competitiveness, efficiency and effectiveness. Additional risks and uncertainties that may affect operating results and business performance are set forth under Item 1A of our most recent Form 10-K, and the Company’s other public filings with the Securities and Exchange Commission. Ecolab does not undertake, and expressly disclaims, any duty to update any forward-looking statement whether as a result of new information, future events or changes in expectations, except as required by law.
