Explanation of Responses:

1. Option granted under the Ecolab Inc. 2005 Stock Incentive Plan on February 20, 2008. 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 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.
