** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Number of UNITS owned by the reporting person in the Ecolab Stock Fund of the Ecolab Savings Plan (401(k) Plan) as of October 31, 2008. Includes 212.413 UNITS acquired by the reporting person in the Ecolab Stock Fund of the Ecolab Savings Plan since the date of his last report. (The 8,643.583 UNITS are the equivalent of approximately 16,166 SHARES of the issuer's Common Stock.)
(2) The option will be exercisable, on a cumulative basis, as to one-third of the option shares (excluding any fractional portion less than one share), on each of the first and second anniversaries of the date of grant and as to the remaining shares on the third anniversary of the date of grant; provided, however, that if a Change in Control (as that term is defined in the 2005 Ecolab Inc. Stock Incentive Plan) will occur, then the option, if it has been outstanding for at least six months from the date of grant, will become immediately exercisable in full.
