The information is comprised of unaudited pro forma condensed consolidated financial information (income statements and balance sheets) for specified periods and dates which give effect to the Transaction as if it had occurred on the historical dates set forth in the published material. This unaudited pro forma information is in addition to certain other Transaction and financial information previously published on Ecolab's web site. Ecolab expects to update such unaudited pro forma information as soon as practical following the filing of Ecolab's Form 10-Q for its second and third fiscal quarters in 2001. Such updated unaudited pro forma condensed consolidated financial information will be similarly filed and be available on Ecolab's web site at HTTP://WWW.ECOLAB.COM/PRESSKIT.HTM through the Transaction closing date. The consolidated financial information to be provided on Ecolab's web site is derived from the historical financial statements of Ecolab and Henkel-Ecolab adjusted for certain pro forma adjustments which are based on the estimates, assumptions and limitations set forth in the preface and related Notes to the unaudited pro forma financial information. The unaudited pro forma condensed consolidated financial information should not be considered indicative of actual results that would have been achieved had the Transaction been consummated on the dates indicated, nor is it necessarily indicative of future operating results.
