On May 8, 2009, the stockholders of Ecolab Inc. ("Ecolab" or the "Company") re-approved the Ecolab Inc. Management Performance Incentive Plan (the "Performance Plan") recommended by the Company's Board of Directors. The Board of Directors had previously amended and restated the Performance Plan on February 27, 2009, subject to stockholder approval.

Ecolab has maintained the Performance Plan and similar, stockholder-approved, performance-based bonus plans continuously since 1994. With the approval of the Performance Plan by the stockholders, performance-based bonuses paid under the plan will continue to qualify for an exemption from the deduction limitations imposed by Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"). Section 162(m) generally prohibits a publicly traded company from deducting certain executive compensation in excess of $1,000,000 per year unless, among other things, the compensation is paid under a stockholder-approved plan containing objective performance criteria.

The Performance Plan is briefly described below. This description is qualified in its entirety by reference to the actual Performance Plan, which is filed as Exhibit (10) to this Form 8-K and incorporated by reference herein.

Awards granted under the Performance Plan will provide for a cash payment to be made to participants solely on account of the attainment of one or more pre-established, objective performance goals. Each performance goal will consist of performance criteria, which will be one or more objectively determinable measures related to individual, business unit or Company performance, and a performance target which is the level at which the relevant performance criteria must be achieved for purposes of determining whether a cash payment is to be made under an award. For purposes of the Performance Plan, the committee administering the plan may choose performance criteria from among one or more of the following measures:

† Diluted earnings per share which is net income or loss per share, diluted, as reported in the Company's audited year-end consolidated statement of income for the plan year ("Income Statement");

† operating income as reported or included in the Income Statement;

† net sales as reported or included in the Income Statement;

† days sales outstanding ("DSO") which is the 12 point average of month-end DSO based on monthly performance for days sales invested in accounts receivable;

† capital expenditures as reported or included in the Company's year-end audited consolidated statement of cash flows for the plan year;

† inventory days on hand ("DOH") which is the average of 12 month-end DOH numbers based on month-end inventory and divided by monthly cost of goods;

† controllable expenses which are those expenses under the control of the participant;

† return on beginning equity which is net income divided by beginning of the year "shareholder's equity" as reported or included in the Company's year-end audited

balance sheet for the plan year; and

† return on net assets which is (x) operating income less income taxes at the applicable rate divided by (y) total assets, less cash and cash equivalents, investments in securities and non-interest bearing liabilities as reported or included in the Company's year-end audited financial statements for the plan year.

The Performance Plan is administered by a committee (the "Committee") appointed by the Company's Board of Directors consisting of two or more members, each of whom is an "outside director" within the meaning of Section 162(m) of the Code. The Committee has the authority to select the participants under the Performance Plan; establish the terms of the awards; determine the time or times when awards will be granted; and establish restrictions and other conditions of the awards. The Committee may reduce or eliminate the compensation or other economic benefit due pursuant to an award.

Participants in the Performance Plan will be those eligible executive officers who are selected by the Committee to receive awards for a plan year. The Committee will determine in writing for each participant the performance goal(s) for the participant. Once the Committee has received the appropriate financial and other data after the end of the plan year, it will determine the extent to which the applicable performance goals have been met and the corresponding amount of the award earned by each participant. In no event, however, may a participant receive more than $5 million pursuant to an award for any plan year. In the event of a participant's termination of employment during a plan year, the Committee may approve the payment of a pro-rated award.

The Performance Plan will remain in effect through and including the plan year ending December 31, 2013, unless earlier suspended or terminated by the Company's Board of Directors. The Performance Plan may be amended in any respect that the Board may deem to be in the best interests of the Company, provided that no amendment shall be effective without the approval of the stockholders of the Company if such approval of the amendment is then required for the Performance Plan to continue to qualify as a performance-based compensation plan pursuant to Section 162(m) of the Code.
