1997 OVERVIEW

Ecolab achieved another year of exceptionally strong financial results in 1997.
It was the sixth consecutive year of record financial results for the company.
These financial accomplishments were recognized in the marketplace as Ecolab's
stock price increased 47 percent during 1997 and, including cash dividends,
yielded a 49 percent total return to shareholders. The more significant
accomplishments included:

                                      [GRAPH]

- - For the second year in a row, the company exceeded all three of its long-term
financial objectives of 15 percent growth in net income per common share, 20
percent return on beginning shareholders' equity and an investment grade balance
sheet.

- - Consolidated net sales reached a record $1.6 billion, an increase of 10
percent over the prior year.

- - The core Institutional and Food & Beverage operations had strong performances.
As a result, the company's gross profit margin reached 56.0 percent of net sales
and the 1997 operating income margin increased to 13.3 percent of net sales;
both representing record levels.

- - Net income for 1997 increased to a record level of $134 million, or basic net
income per common share of $1.03. During 1997, the company also reported diluted
net income per common share, as required under new accounting standards. For
1997, diluted net income per common share was $1.00, a record high and an 18
percent increase over the prior year.

- - The company continued to realize strong operating cash flows and maintained
moderate debt levels. As a result, Ecolab maintained its long-term financial
objective of an investment grade balance sheet and the company's debt was rated
within the "A" categories by the major rating agencies.

- - Return on beginning shareholders' equity reached a record 25.8 percent. 1997
was the sixth consecutive year that the company exceeded its long-term financial
objective to achieve a 20 percent return on beginning shareholders' equity.

- - The company increased its annual dividend rate for the sixth consecutive year.
The annual dividend rate was increased 19 percent to an annual rate of $0.38 per
common share. The company has paid dividends on its common stock for 61
consecutive years.

- - The company's common stock was split two-for-one in the form of a 100 percent
stock dividend paid January 15, 1998 to shareholders of record on December 26,
1997. This was the third such stock split in the last 11 years. All per share
and number of share data included in the 1997 financial report have been
retroactively restated to reflect the stock split, except for the Consolidated
Statement of Shareholders' Equity.

- - The company made several business acquisitions during 1997. At year-end 1997,
the company acquired Gibson Chemical Industries Limited (Gibson) located in
Melbourne, Australia. Gibson is a manufacturer and marketer of cleaning

and sanitizing products, primarily for the Australian and New Zealand
institutional, healthcare and industrial markets. Gibson has been included in
the company's consolidated balance sheet at year-end 1997 and will be included
in the company's consolidated results of operations beginning in 1998. Gibson
had annual sales of approximately $130 million in 1997.

     During 1997, the company also added to its Institutional and Food &
Beverage operations in the United States and to its operations in Canada and in
the Central Africa region through business acquisitions.

     All of these acquisitions have been accounted for as purchases, and
accordingly, the results of their operations have been included in the company's
financial statements from the dates of acquisition. Additional information
related to these acquisitions is included in Note 5 of the notes to consolidated
financial statements.

     Consolidated net sales for 1997 were over $1.6 billion, an increase of 10
percent compared to net sales of nearly $1.5 billion in 1996. Both the company's
U.S. and International operations contributed to this sales growth. Business
acquisitions in 1997 and the annualized effect of businesses acquired in 1996
accounted for approximately one-fourth of the growth in sales for 1997. The
growth in sales also reflected the benefits of new product introductions, an
increased sales-and-service force, new customers and competitive gains. A
continuation of generally good conditions in the hospitality and lodging
industries, particularly in the United States, also had a favorable effect on
sales for 1997.

     Consolidated operating income increased 18 percent for 1997 and reached
$219 million compared to consolidated operating income of $185 million in 1996.
This growth included the benefits of business acquisitions, which accounted for
approximately 20 percent of the increase. The consolidated operating income
margin was 13.3 percent in 1997, a substantial improvement over the 1996
consolidated operating income margin of 12.4 percent. Most of the company's
businesses contributed to these income improvements; however, strong
performances by the core U.S. Institutional and Food & Beverage businesses
during 1997 were the major contributors to the company's overall profit
improvement. The increase in the operating income margin for 1997 reflected a
substantial increase in the gross profit margin, which was partially offset by a
modest increase in selling, general and administrative expenses as a percentage
of net sales. The gross profit margin improved to 56.0 percent in 1997 from a
gross profit margin of 54.7 percent in 1996. The increase in gross profit margin
reflected higher sales levels of the company's more profitable core U.S.
operations, a more stable raw material cost environment and good sales volume
growth, particularly in the sales of new products. The benefits of selling price
increases continued to be limited due to market pressures. Selling, general and
administrative expenses were 42.7 percent of net sales in 1997, compared to 42.3
percent of net sales in 1996. This increase reflected investments in the
sales-and-service force and the higher sales levels of the core U.S. operations,
which have relatively higher selling expenses. These increases were partially
offset by continued tight cost controls, improved sales productivity levels and
strong sales growth during 1997. The company anticipates that the monetary
problems which began in East Asia in late 1997 will slow the growth of
consolidated operating income results in 1998, particularly early in the year.
However, the impact is expected to be limited unless substantially broader areas
of the Asia Pacific region are affected.

     Net income for 1997 reached $134 million, or $1.00 per share on a diluted
basis, and increased 18 percent over last year's net income of $113 million, or
$0.85 per share. Net income improved to 8.2 percent of net sales, compared to


                                                                              29


FINANCIAL DISCUSSION

7.6 percent in 1996. The increase in net income reflected the benefits of strong
operating income performance, lower net interest expense and modestly higher
equity in earnings of the Henkel-Ecolab joint venture, which were partially
offset by increased income taxes.

1996 COMPARED WITH 1995

Consolidated net sales were nearly $1.5 billion in 1996 and increased 11 percent
over net sales of $1.3 billion in 1995. Both the company's U.S. and
International operations contributed to this sales improvement. Businesses
acquired during 1996 and during late 1995 accounted for approximately one-half
of the growth in sales for 1996. New product introductions continued to
contribute significantly to sales growth, with additions to the sales force and
competitive gains also adding to the sales improvement.

     Consolidated operating income reached $185 million in 1996, an increase of
14 percent over operating income of $163 million in 1995. This improvement
included good growth in the company's core U.S. Institutional operations and
double-digit growth in all of the company's other U.S. businesses and in all
major regions of International operations. The consolidated operating income
margin was 12.4 percent in 1996, an improvement over the operating income margin
of 12.1 percent in 1995. The benefits of the company's continuing cost-control
efforts more than offset increased raw material costs and limited selling price
increases.

     Net income for 1996 was $113 million, an increase of 14 percent over net
income of $99 million in 1995. The increase in net income reflected strong
operating income performance and increased equity in earnings of the
Henkel-Ecolab joint venture, partially offset by increases in net interest
expense and income taxes. Diluted net income per common share was $0.85 for 1996
and increased 16 percent over 1995's diluted net income per common share of
$0.73. The comparison of net income per common share benefited from a smaller
number of average shares outstanding in 1996, principally due to the purchase of
approximately 7 million shares of the company's common stock in mid-1995 under
the terms of a "Dutch auction" self-tender offer.

     Sales of the company's U.S. operations were nearly $1.3 billion in 1997 and
increased 11 percent over sales of $1.1 billion in 1996. U.S. sales reflected
strong growth in the core Institutional and Food & Beverage operations and in
Pest Elimination sales and included benefits from business acquisitions,
significant new product introductions, new customers and competitive gains,
investments in the sales-and-service force and a continuation of good business
trends in the hospitality and lodging industries. The benefits of selling price
increases continued to be limited due to tight pricing conditions in several of
the markets in which the company does business. Business acquisitions accounted
for approximately 25 percent of U.S. sales growth for 1997. Sales of the U.S.
Institutional Division increased 10 percent for 1997. Institutional's growth
reflected strong sales in all of its business units, significant new customer
business and competitive gains, continued strong growth in its ECOTEMP program
and the successful rollout of its new KEYSTONE product line sold through
partnership with a distributor. The Pest Elimination Division also reported a 10
percent sales growth for 1997, despite increased competitive activity. Pest
Elimination continues to develop new programs to leverage its alliances with
Ecolab's other divisions. Sales of Kay's U.S. operations increased 6 percent for
1997. Kay was unfavorably affected by a more competitive quickservice market;
however, Kay added another major quickservice chain customer in 1997 and had
good growth in sales to the grocery market, which it entered last year. Sales of
the Textile Care Division decreased 3 percent for 1997. Continued plant
consolidations, particularly in laundries serving the healthcare market,
increased competitive activity and comparison against periods that benefited
significantly from new product introductions unfavorably affected Textile Care's
sales growth. The company expects the U.S. Textile Care

business to continue to experience challenging market conditions over the near
term. The Professional Products Division reported sales growth of 12 percent for
1997. This sales improvement reflected last year's acquisition of Huntington
Laboratories, good growth in sales to corporate accounts, and the addition of
new products to its commercial mass distribution line. Sales of the company's
Water Care Services Division were down 2 percent for 1997 and reflected the
elimination of low margin business, consolidation of business acquisitions made
over the past three years, integration of disparate product lines, and the
refining of sales efforts. The Food & Beverage Division reported a sales
increase of 24 percent for 1997. Food & Beverage sales growth included the
benefits of Chemidyne, a provider of cleaning and sanitizing products and
equipment to the meat, poultry and processed food markets, which was acquired in
August 1997, and the annualized effect of the acquisition of Monarch in August
of 1996. Excluding these business acquisitions, Food & Beverage sales growth was
9 percent for 1997 and included growth in sales to all of its markets with
double-digit growth in sales to the food processing and beverage markets.

     Operating income for the company's U.S. operations reached $196 million, an
increase of 19 percent over operating income of $165 million in 1996. Business
acquisitions accounted for approximately 20 percent of U.S. operating income
growth for 1997. With the exception of the Textile Care Division, all of the
company's U.S. businesses reported increased operating income, with particularly
strong growth in the core Institutional and Food & Beverage operations. The U.S.
operating income margin improved to 15.3 percent of net sales from 14.4 percent
in 1996. The improved operating income margin reflected the benefits of strong
core business sales, sales of new products, stable raw material costs, sales
productivity improvements and tight cost controls, which were partially offset
by investments in the sales-and-service force. During 1997, the company added
approximately 285 sales-and-service personnel, including Chemidyne associates.

1996 COMPARED WITH 1995

Sales of the company's U.S. operations exceeded $1.1 billion in 1996, an
increase of 12 percent over U.S. sales of $1.0 billion in 1995. U.S. sales
growth reflected business acquisitions and the benefits of significant new
product introductions. Business acquisitions accounted for approximately
one-half of the increase in U.S. sales. Sales of the U.S. Institutional Division
increased 4 percent for 1996. Institutional sales growth reflected competitive
gains and continued strong growth in its ECOTEMP program and the specialty
products group. Pest Elimination sales increased 12 percent over the prior year,
reflecting new business and a continued high retention of key customers. Kay's
U.S. operations reported sales growth of 11 percent for 1996 due to new customer
business and the growth of the large quickservice chains, which are the core of
Kay's business. The Textile Care Division reported sales growth of 9 percent for
1996, with continued success in sales of new products and double-digit growth in
sales to the commercial laundry market. Sales of the company's Professional
Products Division nearly doubled due to the February 1996 acquisition of
Huntington Laboratories. Excluding sales of the Huntington operations,
Professional Products sales for 1996 increased 3 percent over 1995, principally
due to sales growth of its Airkem products. Sales of the Food & Beverage
Division increased 13 percent for 1996 and included the operations of Monarch
since its acquisition from H.B. Fuller in August 1996. Excluding Monarch sales,
Food & Beverage sales growth was 5 percent for 1996, and reflected new customer
gains and good growth in sales to the beverage and food processing markets.
Sales of the company's recently formed Water Care Services Division more than
doubled during 1996 due to the annualization of sales from business acquisitions
and sales gained by successfully leveraging its alliances with Ecolab's other
divisions.

     Operating income for the company's U.S. businesses totaled $165 million for
1996 and increased 12 percent over operating income of $147 million in 1995. The
growth in operating income included good growth in the company's U.S.
Institutional business and double-digit increases in operating income of all of
the company's other U.S. divisions. The U.S. operating income margin was 14.4
percent, up slightly compared to the operating income margin of 14.3 percent in
1995. The improvement in operating income margin reflected higher sales levels,
sales productivity gains and the benefits of company-wide cost-control programs.

     The company's International business consists of established major
operations in Asia Pacific, Latin America and Canada. In addition, on a smaller
scale, Kay serves various international markets and the company has start-up
operations in Africa and serves various international locations through its
export business. Net sales of the company's International operations totaled
$365 million for 1997, which represented growth of 7 percent over sales of $341
million in 1996. International sales growth included benefits of business
acquisitions and significant new product introductions. Businesses acquired in
Canada and Africa in 1997 and the annualization of 1996 Canadian business
acquisitions accounted for approximately 50 percent of International's sales
growth for 1997. Changes in currency translation had a negative impact on
reported sales, particularly in the Asia Pacific region. Excluding the effects
of currency translation, sales of International operations increased 11 percent
for 1997. The Asia Pacific region, International's largest operation, reported
sales growth of 2 percent for 1997. However, when measured in local currencies,
Asia Pacific had sales growth of 9 percent with double-digit growth in Japan,
modest growth in New Zealand and flat results in Australia. Asia Pacific sales
to institutional markets increased at double-digit rates and the region recorded
good growth in sales to the food and beverage markets. The acquisition of
Gibson, primarily serving the Australian and New Zealand institutional,
healthcare and industrial markets, was effective at year-end 1997 and will add
significantly to the company's operations in the Asia Pacific region in 1998.
Latin America reported U.S. dollar sales growth of 9 percent for 1997. The
effects of changes in currency translation did not have a significant impact on
Latin America's reported sales. Growth in the Latin America region was led by
Mexico with significant double-digit growth and included good growth in Brazil.
The region reported double-digit growth in sales to the food and beverage
markets and good growth in Institutional sales. Canada reported sales growth of
15 percent for 1997, which included a modest negative impact from changes in
currency translation. Approximately 70 percent of Canada's sales growth was due
to business acquisitions. Canada's results also included good growth in sales to
the institutional and food and beverage markets. Overall International sales
results for 1997 included the benefits of business acquisitions in Central
Africa during 1997 and good growth in sales of Kay's international operations.
Sales in South Africa decreased during 1997, principally due to the elimination
of low margin business.

     Operating income for International's operations totaled $27 million in 
1997, an increase of 13 percent over operating income of $24 million in 1996. 
Business acquisitions accounted for approximately 40 percent of the growth in 
International's operating income for 1997. Excluding the effects of currency 
translation, International operating income growth was 21 percent for 1997. 
Reported operating income margins improved to 7.4 percent of net sales in 
1997 compared with 7.0 percent in 1996. Double-digit operating income growth 
in Asia Pacific and Canada more than offset a decrease in operating income in 
the Latin America region, which was principally due to investments in Brazil 
and Argentina. The company expects the monetary problems that began in East 
Asia in late 1997 to impact the Asia Pacific region in 1998. Although the 
company's operations in the areas primarily affected are limited, the company 
is cautious about growth for the year due to the uncertain economic 
conditions in the region.

     Operating income margins of the company's International operations are
substantially less than the operating income margins realized for the company's
U.S. operations. The lower International margins are due to the difference in
scale of International operations, where operating locations are smaller in
size, and to the additional costs of operating in numerous and diverse foreign
jurisdictions. Proportionately larger investments in sales and administrative
personnel are also necessary in order to facilitate growth of International
operations.

1996 COMPARED WITH 1995

Total revenues for International operations of $341 million in 1996 increased 10
percent over revenues of $311 million in 1995. International's sales growth
reflected the benefits of business acquisitions and sales of new products.
Business acquisitions accounted for approximately 40 percent of International's
sales growth over 1995. Changes in currency translation had a negative impact on
sales, particularly in the Asia Pacific region. Asia Pacific reported sales
growth of 4 percent for 1996. When measured in local currencies, the Asia
Pacific region had sales

growth of 9 percent, with double-digit growth in Japan and New Zealand and
modest growth in Australia. Reported sales of the Latin America region increased
13 percent over the prior year. Excluding the effects of currency translation,
Latin America recorded sales growth of 16 percent for 1996, which included a
continuation of significant double-digit growth in Brazil and good sales growth
in Mexico and Puerto Rico. Sales in Canada increased 9 percent over sales in
1995 and reflected the benefits of the Huntington and Monarch acquisitions and
good growth in sales to institutional markets. Sales in South Africa more than
doubled over the prior year, reflecting the annualization of sales from
businesses acquired in late 1995. Sales of Kay's international operations
increased 16 percent for 1996.

     The company's International operations reported operating income of $24
million in 1996, an increase of 22 percent over operating income of $20 million
in 1995. Excluding the effects of currency translation, International operating
income growth was 29 percent for 1996. The reported operating income margin
improved to 7.0 percent compared with the operating income margin of 6.3 percent
in the prior year. Operating income results included double-digit growth and
improved operating income margins in each of the major regions of Asia Pacific,
Latin America and Canada, with a continuation of particularly strong growth in
Brazil.

HENKEL-ECOLAB JOINT VENTURE

The company operates institutional and industrial cleaning and sanitizing
businesses in Europe through its 50 percent economic interest in the
Henkel-Ecolab joint venture. The company includes the operations of the
Henkel-Ecolab joint venture in its financial statements using the equity method
of accounting. The company's equity in earnings of the joint venture, including
royalty income and after deduction of intangible amortization, was $13 million
in 1997, a 3 percent increase over 1996. Results were negatively affected by the
stronger U.S. dollar. When measured in Deutsche marks, net income of the joint
venture increased 11 percent and reflected increased sales, improved gross
margins and lower interest expense, partially offset by investments in the
sales-and-service force.

     Joint venture sales, although not consolidated in Ecolab's financial
statements, increased 7 percent for 1997 when measured in Deutsche marks and
included the benefits of a business acquisition, benefits of new product
transfers from Ecolab to the joint venture and good sales to the institutional
and food hygiene markets. When measured in U.S. dollars, however, joint venture
sales for 1997 decreased 7 percent.

1996 COMPARED WITH 1995

The company's equity in earnings of the Henkel-Ecolab joint venture was $13
million for 1996, a 69 percent increase over weak results of $8 million in 1995.
The improvement reflected the benefits from a number of cost-control programs
that were put into effect in 1996. Operating results at the joint venture also
reflected lower interest expense and lower overall income tax rates. Joint
venture revenues increased 4 percent for 1996 when measured in Deutsche marks.
When measured in U.S. dollars, joint venture sales were negatively affected by
the strengthening U.S. dollar, and totaled $905 million, just below the $909
million of sales recorded for 1995.

CORPORATE

Corporate operating expense was $4 million in 1997, $3 million in 1996 and $4
million in 1995. Corporate operating expense includes overhead costs directly
related to the joint venture.

INTEREST AND INCOME TAXES

Net interest expense decreased 12 percent to less than $13 million in 1997,
compared to net interest expense of over $14 million in 1996. This decrease was
principally due to a scheduled debt repayment on the company's 9.68 percent
senior notes and to increased interest income earned on higher average levels of
cash and cash equivalents held during 1997. The company anticipates that its net
interest expense will increase substantially for 1998 compared with 1997 levels,
due to borrowings incurred under the Multicurrency Credit Agreement in late 1997
for the Gibson acquisition.

     Net interest expense for 1996 increased 25 percent over net interest
expense of $12 million in 1995. This increase was due to higher debt levels
during 1996, particularly during the first half of the year, reflecting cash
used during 1995 for the stock purchase self-tender offer and for business
acquisitions during late 1995 and during 1996.


                                                                              33


FINANCIAL DISCUSSION

     The company's annual effective income tax rate was 41.5 percent for 1997, a
modest increase from the 1996 effective income tax rate of 41.4 percent. This
increase was due to a slightly higher overall effective rate on earnings of
International operations. International's effective income tax rate varies from
year to year with the pre-tax income mix of the various countries in which the
company operates and savings related to the availability of one-time tax
strategies.

     The company's annual effective income tax rate of 41.4 percent in 1996
increased from 39.5 percent in 1995. The increase in the effective income tax
rate for 1996 was primarily due to a higher overall effective rate on earnings
of International operations and to the effects of business acquisitions.

     As a result of tax losses on the disposition of a discontinued business in
1992, the company's U.S. federal income tax payments were reduced in 1995 and
prior years by a total of approximately $58 million, including $3 million in
1995. However, pending final acceptance of the company's treatment of the
losses, no income tax benefit has been recognized for financial reporting
purposes. Additional reductions in U.S. federal income tax payments are not
anticipated.

YEAR 2000 CONVERSION

The "year 2000" issue is the result of computer programs having date-sensitive
software which may recognize a date using "00" as the year 1900 rather than the
year 2000. This can result in system failure or miscalculations. The company
recognizes the need to ensure that its operations will not be adversely affected
by year 2000 issues and is establishing processes which it believes will be
sufficient to evaluate and manage risks associated with the problem.

     The company has largely completed a review of year 2000 compliance for its
critical operating and application systems, particularly customer-oriented
systems such as sales and order processing, billing and collections. As a
result, the company has determined that it will be required to modify or replace
significant portions of its software. This process is in progress and the
intention is to complete it by the end of 1998. The costs are not expected to be
significant.

     The company is also in the process of analyzing its dispensing and cleaning
systems and its manufacturing and building maintenance operations for dependence
on date-sensitive software to identify and resolve any relevant issues in
advance of the year 2000. Although a final cost estimate has not been
determined, at this time the company does not believe the cost will be material.
The company has begun the process of surveying key suppliers, vendors and
customers to determine the status of such third parties' year 2000 remediation
plans. If the company were to determine that a supplier, vendor or customer will
not be able to remediate its year 2000 issue, the company would anticipate
taking such steps as it reasonably could to mitigate the effects.

     As part of its year 2000 process the company anticipates testing its
systems for compliance; however, at this time only limited testing has occurred.

     Risks and uncertainties associated with the year 2000 conversion are
discussed in the company's Form 10-K for the year ended December 31, 1997 under
the heading "Forward-Looking Statements and Risk Factors".

FINANCIAL POSITION, CASH FLOWS AND LIQUIDITY

FINANCIAL POSITION

The company reached its long-term financial objective of an investment grade
balance sheet in 1993 and has continued to maintain this objective for the last
five years. The company's debt was rated within the "A" categories by the major
rating agencies during 1997. Significant changes to the company's balance sheet
during 1997 included the following:

- - The company's balance sheet as of December 31, 1997 reflected the assets and
liabilities of Gibson and the other businesses acquired during 1997. The
increase in other noncurrent assets from year-end 1996 was principally due to
these acquisitions. Significant levels of accounts receivable, inventories,
property, plant and equipment and other current liabilities were also added
during 1997 as a result of these business acquisitions.

- - Total debt was $308 million as of December 31, 1997 and increased from total
debt of $176 million at year-end 1996 and $161 million at year-end 1995. The
increase in total debt during 1997 included $116 million of borrowings incurred
under the company's Multicurrency Credit Agreement to finance the purchase of
the outstanding common shares of Gibson, and $22 million of debt which was
included on Gibson's balance sheet at the time of acquisition. As of December
31, 1997, the ratio of total debt to capitalization was 36 percent, compared to
25 percent at year-end 1996 and 26 percent at year-end 1995.

FINANCIAL DISCUSSION

     In late 1997, the company amended and restated its $225 million
Multicurrency Credit Agreement in order to provide for financing of the Gibson
acquisition. The amended and restated agreement increased the credit available
to $275 million, extended the term one year to September 2002 and specifically
provided for anticipated borrowings of Australian dollars.

- - Working capital was $105 million at December 31, 1997, compared with working
capital of $108 million at year-end 1996 and $48 million at year-end 1995. The
levels of cash and cash equivalents and short-term debt at year-end 1995 were
affected by the company's stock purchase self-tender offer in mid-1995.

- - The lower level of the company's investment in the Henkel-Ecolab joint venture
at year-end 1997 was principally due to the effects of changes in currency
translation and dividends which were received from the joint venture.

- - Other noncurrent liabilities were $125 million at December 31, 1997 and
decreased from year-end 1996 due to an income tax deposit made against
outstanding federal income tax issues.

- - The company capitalizes certain costs of computer software developed or
obtained for internal use. The amounts capitalized are not significant and the
company's policy for the capitalization of these costs is consistent with the
guidelines included in the American Institute of Certified Public Accountants
recent Statement of Position for accounting for costs of computer software
developed or obtained for internal use.

CASH FLOWS

For 1997, the company generated $235 million of cash from continuing operating
activities, compared with $254 million in 1996 and $163 million in 1995. The
decrease in operating cash flows from 1996 reflected the reversal of favorable
timing of payments, which affected the fourth quarter of 1996 and an income tax
deposit made in 1997 against outstanding federal income tax issues that had been
accrued for in other noncurrent liabilities. The decrease also reflected
favorable cash flows during 1996 from the collection of accounts receivable
related to strong fourth quarter 1995 sales. The comparison of cash provided by
continuing operating activities was favorably affected by increased earnings
during 1997 and higher dividends received from the Henkel-Ecolab joint venture.

                                      [GRAPH]

     Cash provided by discontinued operations in 1995 reflects a reduction in
income tax payments as a result of the loss on the disposition of a discontinued
business.

     Cash flows used for investing activities included capital expenditures of
$122 million in 1997, $112 million in 1996 and $110 million in 1995. Worldwide
additions of merchandising equipment, primarily cleaning and sanitizing product
dispensers, accounted for approximately 70 percent of each year's capital
expenditures. The company has expanded its manufacturing facilities over the
last two years through construction and business acquisitions in order to meet
sales requirements more efficiently. Cash was also used in 1997 for business
acquisitions, primarily Gibson and Chemidyne.

     Cash provided by financing activities included $116 million of debt
incurred under the Multicurrency Credit Agreement to acquire Gibson. Strong
operating cash flows were used to provide cash for shares reacquired, cash
dividends and a scheduled repayment on the company's 9.68 percent senior notes.

     In 1997, the company increased its annual dividend rate for the sixth
consecutive year. The company has paid dividends on its common stock for 61
consecutive years. Cash dividends declared per share of common stock, by
quarter, for each of the last three years were as follows:



                    First      Second       Third      Fourth

1996               0.07        0.07        0.07        0.08        0.29
1995               0.0625      0.0625      0.0625      0.07        0.2575



LIQUIDITY

The company maintains a committed line of credit under the Multicurrency Credit
Agreement for general corporate financing needs. The agreement includes a
competitive bid feature to minimize the cost of the company's borrowings. The
company also has a $200 million shelf registration as an alternative source of
liquidity. The company believes its existing cash balances, cash generated by
operating activities, including cash flows from the joint venture, and available
credit are adequate to fund all of its 1998 requirements for growth, possible
acquisitions, new program investments, scheduled debt repayments and dividend
payments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF BUSINESS

The company is the leading global developer and marketer of premium cleaning,
sanitizing and maintenance products and services for the hospitality,
institutional and industrial markets. Customers include hotels and restaurants;
foodservice, healthcare and educational facilities; quickservice (fast-food)
units; commercial laundries; light industry; dairy plants and farms; and food
and beverage processors around the world.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the company and
all majority-owned subsidiaries. The company accounts for its investment in the
Henkel-Ecolab joint venture under the equity method of accounting. International
subsidiaries and the Henkel-Ecolab joint venture are included in the financial
statements on the basis of their November 30 fiscal year ends.

FOREIGN CURRENCY TRANSLATION

Financial position and results of operations of the company's international
subsidiaries and the Henkel-Ecolab joint venture generally are measured using
local currencies as the functional currency. Assets and liabilities of these
operations are translated at the exchange rates in effect at each fiscal year
end. Income statement accounts are translated at the average rates of exchange
prevailing during the year. Translation adjustments arising from the use of
differing exchange rates from period to period are included in the cumulative
translation account in shareholders' equity. Translation adjustments for
operations in highly inflationary economies are included in net income and were
not significant.

CASH AND CASH EQUIVALENTS

Cash equivalents include highly liquid investments with a maturity of three
months or less when purchased.

INVENTORY VALUATIONS

Inventories are valued at the lower of cost or market. Domestic chemical
inventory costs are determined on a last-in, first-out (lifo) basis. Lifo
inventories represented 40 percent, 44 percent and 38 percent of consolidated
inventories at year-end 1997, 1996 and 1995, respectively. All other inventory
costs are determined on a first-in, first-out (fifo) basis.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost. Merchandising equipment
consists principally of various systems that dispense cleaning and sanitizing
products and low-temperature dishwashing machines. The dispensing systems are
accounted for on a mass asset basis, whereby equipment is capitalized and
depreciated as a group and written off when fully depreciated. Depreciation and
amortization are charged to operations using the straight-line method over the
assets' estimated useful lives.

INTANGIBLE ASSETS

Intangible assets arise principally from business acquisitions and are stated at
cost. The assets are amortized on a straight-line basis over their estimated
economic lives, generally not exceeding 30 years.

LONG-LIVED ASSETS

The company periodically assesses the recoverability of long-lived and
intangible assets based on anticipated future earnings and operating cash flows.

NET INCOME PER COMMON SHARE

In the fourth quarter of 1997, the company adopted Statement of Financial
Accounting Standards No. 128, a new standard of computing and presenting both
basic and diluted net income per common share amounts. All prior periods have
been changed to conform with the new presentation. However, basic and diluted
net income per share amounts are generally consistent with net income per share
amounts previously reported.

     The computation of the basic and diluted per share amounts were as follows:



(thousands, except per share)                 1997           1996           1995

  Diluted                                 $   1.00       $   0.85       $   0.73


     Virtually all stock options outstanding for each of these periods were
dilutive and included in the calculation of the diluted per share amounts.

USE OF ESTIMATES

The preparation of the company's financial statements requires management to
make certain estimates and assumptions that affect the reported amounts of
assets and liabilities as of the date of the financial statements and the
reported amounts of revenues and expenses during the reporting periods. Actual
results could differ from these estimates.

     The 9.68 percent senior notes include covenants regarding consolidated
shareholders' equity and amounts of certain long-term debt.

     In late 1997, the company amended and restated its $225 million
Multicurrency Credit Agreement, increasing the credit available to $275 million,
extending the term one year to September 2002, and specifically providing for
anticipated borrowings of Australian dollars to acquire the outstanding shares
of Gibson Chemical Industries Limited, as described in Note 5. The terms of the
amended and restated agreement are otherwise generally similar to the agreement
which it replaced. The company may borrow varying amounts from time to time on a
revolving credit basis, with loans denominated in G-7 currencies, or certain
other currencies, if available. The company has the option of borrowing based on
various short-term interest rates. The agreement includes a covenant regarding
the ratio of total debt to capitalization. Amounts outstanding under the
agreement at year-end 1997 were denominated in Australian dollars and had an
average annual interest rate of 5.2 percent.

     In October 1996, the company filed a shelf registration with the Securities
and Exchange Commission for the issuance of up to $200 million of debt
securities. The filing is intended to enhance the company's future financial
flexibility in funding general business needs. The company has no immediate
plans to issue debt under the registration.

     As of December 31, the weighted-average interest rate on notes payable was
5.4 percent for 1997, 5.1 percent for 1996 and 6.3 percent for 1995.

     As of December 31, 1997, the aggregate annual maturities of long-term debt
for the next five years were: 1998 - $15,444,000; 1999 - $15,184,000; 2000 -
$15,155,000; 2001 - $14,988,000 and 2002 - $126,770,000.

     Interest expense was $18,043,000 in 1997, $19,084,000 in 1996 and
$15,857,000 in 1995. Total interest paid was $18,168,000 in 1997, $16,897,000 in
1996 and $16,170,000 in 1995.

     Other noncurrent liabilities included income taxes payable of $82 million
at December 31, 1997, $100 million at December 31, 1996 and $96 million at
December 31, 1995. Income taxes payable reflected a reduction in U.S. federal
income tax payments during 1995 and prior years, as a result of tax losses on
the disposition of a discontinued business in 1992.

4. FINANCIAL INSTRUMENTS

FOREIGN CURRENCY INSTRUMENTS

The company uses hedging and derivative financial instruments to limit financial
risk related to foreign currency exchange rates, interest rates and other market
risks. The company does not hold hedging or derivative financial instruments of
a speculative nature.

     The company enters into foreign currency forward and option contracts to
hedge specific foreign currency exposures, principally related to intercompany
debt and joint venture royalty transactions. These contracts generally expire
within one year. Gains and losses on these contracts are deferred and recognized
as part of the specific transactions hedged. The cash flows from these contracts
are classified in the same category as the transaction hedged in the
Consolidated Statement of Cash Flows.


                                                                              41


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

4. FINANCIAL INSTRUMENTS (continued)

The company had foreign currency forward exchange contracts with a face amount
denominated primarily in Deutsche marks and totaling approximately $70 million
at December 31, 1997, $115 million at December 31, 1996 and $125 million at
December 31, 1995. The unrealized gains on these contracts were not significant.

     The carrying amounts of cash equivalents and short-term debt approximate
fair value because of their short maturities.

     Long-term investments in securities are carried at cost. The carrying
amount of these securities approximates fair value based on quoted market
prices. These securities mature in periods of less than 10 years.

     The fair value of long-term debt is based on quoted market prices for the
same or similar issues.

5. BUSINESS ACQUISITIONS

GIBSON BUSINESS ACQUISITION

In October 1997, the company made a public tender offer for all of the 
outstanding stock of Gibson Chemical Industries Limited (Gibson) located in 
Melbourne, Australia. Gibson is a manufacturer and marketer of cleaning and 
sanitizing products, primarily for the Australian and New Zealand 
institutional, healthcare and industrial markets. On November 5, 1997, the 
company waived all of the remaining conditions to its tender offer and, 
effective November 30, 1997, had acquired substantially all of the 
outstanding Gibson shares.

     The acquisition has been accounted for as a purchase. The purchase price of
the shares and the direct costs of the transaction totaled approximately $130
million and were financed through the company's Multicurrency Credit Agreement.
The company's international subsidiaries are included in the financial
statements on the basis of their November 30 fiscal year ends, and, therefore,
Gibson's operations are not included in the company's Consolidated Statement of
Income for 1997. The assets acquired and the liabilities assumed in the
transaction are included in the company's Consolidated Balance Sheet as of the
November 30 effective date.

     The company's plan for integration is not complete and, therefore, the
allocation of the purchase price to the assets acquired and the liabilities
assumed is preliminary. The significant open issues in the integration plan are
the determination of which of the acquired businesses may not be retained, and
decisions relative to certain duplicate facilities. Management expects the
integration plan to be completed near the end of the first quarter of 1998.

     The following unaudited pro forma financial information reflects the
combined results of the company and Gibson assuming the acquisition had occurred
at the beginning of 1997.

     The pro forma results are presented for information purposes only and
include all of the acquired Gibson businesses and the preliminary purchase
accounting as described above. Therefore, the pro forma results do not reflect
any purchase accounting refinements that may arise when the integration plan is
completed and approved. At that time, the pro forma results for Gibson will be
adjusted to reflect the final plan.

OTHER BUSINESS ACQUISITIONS

     In January 1997, the company acquired three small institutional and food
and beverage businesses in the Central Africa region. Sales of the acquired
businesses were approximately $6 million in 1996.

     In March 1997, the company acquired the institutional, food and beverage
and commercial laundry cleaning and sanitizing businesses of the Savolite Group,
which is based in Vancouver, British Columbia, Canada. The acquired Savolite
businesses complement the company's operations, primarily in Canada, with
limited operations also in the U.S. Pacific Northwest. Sales of the acquired
Savolite businesses were approximately $8 million in 1996.

     In August 1997, the company acquired the Chemidyne Marketing Division of
Chemidyne Corp. in Macedonia, Ohio. Chemidyne Marketing is a provider of
cleaning and sanitizing products and equipment to the meat, poultry and
processed food markets in the United States. Chemidyne Marketing has become part
of the company's Food & Beverage Division. Sales of the acquired Chemidyne
business were approximately $17 million in 1996.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In December 1997, the company issued common stock to purchase the specialty
chemical business of Grace-Lee Products Incorporated, a Minneapolis,
Minnesota-based manufacturer and marketer of cleaning products for the U.S.
industrial market. Sales of the business acquired, which primarily serves the
vehicle wash market, were approximately $16 million in 1996. The acquired
Grace-Lee business has become part of the company's Institutional Division.

     These acquisitions have been accounted for as purchases and, accordingly,
the results of their operations have been included in the financial statements
of the company from the dates of acquisition. Net sales and operating income of
these businesses were not significant.

     Cash paid for income taxes was approximately $100 million in 1997, $72 
million in 1996 and $55 million in 1995. As a result of tax losses on the 
disposition of a discontinued business in 1992, the company's U.S. federal 
income tax payments were reduced in 1995 and prior years by a total of 
approximately

                                                                              43


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

7. INCOME TAXES (continued)

$58 million, including $3 million in 1995. However, pending final
acceptance of the company's treatment of the losses, no income tax benefit has
been recognized for financial reporting purposes. These income tax benefits will
be recognized as income attributable to discontinued operations to the extent
the company's treatment of the losses is accepted.

     As of December 31, 1997, undistributed earnings of international
subsidiaries and the Henkel-Ecolab joint venture of approximately $43 million
and $46 million, respectively, were considered to have been reinvested
indefinitely and, accordingly, the company has not provided U.S. income taxes on
such earnings. If those earnings were remitted to the company, applicable income
taxes would be offset substantially by available foreign tax credits.

8. RETIREMENT PLANS

PENSION PLANS

The company has a noncontributory defined benefit pension plan covering
substantially all of its U.S. employees. Plan benefits are based on years of
service and highest average compensation for five consecutive years of
employment. Various international subsidiaries also have defined benefit pension
plans. Pension expense included the following components:

     The company's policy is to fund pension costs currently to the extent
deductible for income tax purposes. U.S. pension plan assets consist primarily
of equity and fixed income securities. International pension benefit obligations
and plan assets were not significant.

     U.S. pension plan assumptions, in addition to projections for employee
turnover and retirement ages, were:

     At December 31, 1996, the company updated the mortality assumptions used in
its actuarial pension plan calculations. The effect of this change and a change
in 1995 for projected salary increases, as well as the effect of changes in the
discount rate used for determining the year-end pension benefit obligations and
future service and interest cost was:

Projected benefit obligation                 $22.5         $  1.2       $  17.6


     The company also has noncontributory non-qualified defined benefit plans
which provide for benefits to employees in excess of limits permitted under its
U.S. pension plan. The recorded obligation for these plans was approximately $11
million at December 31, 1997 and the annual expense for these plans was
approximately $2 million in each of the years 1997, 1996 and 1995.

POSTRETIREMENT HEALTH CARE BENEFITS

The company provides postretirement health care benefits to substantially all
U.S. employees. The plan is contributory based on years of service and family
status, with retiree contributions adjusted annually.

     Employees outside the U.S. are generally covered under government-sponsored
programs and the cost for providing benefits under company plans was not
significant.

     Postretirement health care benefits expense was:

     The assumptions for the discount rate and expected return on plan assets
for the postretirement health care benefits plan were:



                                              1997           1996          1995
- ----------------------------------        --------       --------      --------
                                                              
Discount rate for service and interest
     cost, at beginning of year               7.75%          7.50%         8.25%
Expected return on plan assets                 9.0            9.0           6.0
Discount rate for year-end
     benefit obligation                       7.25%          7.75%         7.50%


     The decrease in the discount rate at year-end 1997 resulted in an increase
in the accumulated benefit obligation of approximately $7 million. All other
changes in the discount rate and the expected rate of return on plan assets did
not have a significant effect on the expense or obligation of the plan. Plan
assets consist primarily of equity and fixed income securities.

     For measurement purposes, 9.5 percent (for pre-age 65 retirees) and 7.5
percent (for post-age 65 retirees) annual rates of increase in the per capita
cost of covered health care were assumed for 1998. The rates were assumed to
decrease gradually to 6.5 percent and 5.5 percent, respectively, at 2001 and
remain at that level thereafter. Health care costs which are eligible for
subsidy by the company are limited to a 4 percent annual increase beginning in
1996 for most employees. An increase in the assumed health care cost trend rate
by one percentage point in each year would increase the accumulated
postretirement benefit obligation as of year-end 1997 by approximately $6
million and 1997 expense by approximately $0.4 million.

SAVINGS PLAN

The company provides a 401(k) savings plan for substantially all U.S. employees.
Employee contributions of up to 6 percent of eligible compensation are matched
50 percent by the company. The company's contributions are invested in Ecolab
common stock and amounted to $7,156,000 in 1997, $6,622,000 in 1996 and
$5,919,000 in 1995.

9. STOCK INCENTIVE AND OPTION PLANS

The company's stock incentive and option plans provide for grants of stock
options and stock awards. Common shares available for grant as of December 31
were 5,274,652 for 1997, 840,096 for 1996 and 2,249,536 for 1995.

     Options may be granted to purchase shares of the company's stock at not
less than fair market value at the date of grant. Options generally become
exercisable over periods of up to four years from date of grant and expire
within ten years from date of grant. Stock option transactions were:

     Stock awards are generally subject to restrictions, including forfeiture in
the event of termination of employment. Restrictions generally lapse over
periods of up to four years. The value of a stock award at date of grant is
charged to income over the periods during which the restrictions lapse.

     The company adopted Statement of Financial Accounting Standards No. 123, a
new standard of accounting and reporting for stock-based compensation plans, in
1996. The company has continued to measure compensation cost for its stock
incentive and option plans using the intrinsic value-based method of accounting
it has historically used and, therefore, the new standard has no effect on the
company's operating results.

     Had the company used the fair value-based method of accounting for its
stock option and incentive plans beginning in 1995 and charged compensation cost
against income, over the vesting periods, based on the fair value of options at
the date of grant, net income and diluted net income per common share for 1997,
1996 and 1995 would have been reduced to the following pro forma amounts:

     The pro forma information above only includes stock options granted since
1995. Compensation expense under the fair value-based method of accounting will
increase over the next few years as additional stock option grants are
considered.

     The weighted-average grant-date fair value of options granted for 1997,
1996 and 1995 and the significant assumptions used in determining the underlying
fair value of each option grant on the date of grant utilizing the Black-Scholes
option-pricing model were as follows:

10. SHAREHOLDERS' EQUITY

The company's common stock was split two for one in the form of a 100 percent
stock dividend paid January 15, 1998 to shareholders of record on December 26,
1997. All per share and number of share data have been retroactively restated to
reflect the stock split, except for the Consolidated Statement of Shareholders'
Equity.

     Authorized common stock, par value $1.00 per share, was 200 million shares
in 1997 and 100 million shares in 1996 and 1995. Treasury stock is stated at
cost. Dividends declared per share of common stock were $0.335 for 1997, $0.29
for 1996 and $0.2575 for 1995.

     The company has 15 million shares, without par value, of authorized but
unissued preferred stock.

     Each share of outstanding common stock entitles the holder to one-half of a
preferred stock purchase right. A right entitles the holder, upon occurrence of
certain events, to buy one one-hundredth of a share of Series A Junior
Participating Preferred Stock at a purchase price of $115, subject to
adjustment. The rights, however, will not become exercisable unless and until,
among other things, any person or group acquires 15 percent or more of the
outstanding common stock of the company, or the company's board of directors
declares a holder of 10 percent or more of the outstanding common stock to be an
"adverse person" as defined in the rights plan. Upon the occurrence of either of
these events, the rights will become exercisable for common stock of the company
(or in certain cases common stock of an acquiring company) having a market value
of twice the exercise price of a right. The rights provide that the holdings by
Henkel KGaA or its affiliates, subject to compliance by Henkel with certain
conditions, will not cause the rights to become exercisable nor cause Henkel to
be an "adverse person." The rights are redeemable under certain circumstances at
one cent per right and, unless redeemed earlier, will expire on March 11, 2006.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The company maintains a share repurchase program which is intended to offset the
dilutive effect of shares issued for employee benefit plans. The company
reacquired 1,944,600 shares of its common stock in 1997 and 1,154,600 shares in
1996 under this program through open and private market purchases. The company
anticipates that it will continue to periodically reacquire shares under its
share repurchase program.

     In June 1995, the company purchased approximately 7 million shares
(approximately 5 percent of total shares then outstanding) of its common stock
at a price of $12.50 per share pursuant to the terms of a "Dutch auction"
self-tender offer. The total purchase price for these shares was approximately
$90 million and was funded by excess cash and cash equivalents and by
approximately $30 million of short-term borrowings. The company also reacquired
616,800 shares in 1997 and 105,800 shares in 1996 under this program and the
company may purchase approximately 4.2 million additional shares from time to
time through open market and privately negotiated transactions to complete the
remaining portion of a 12 million share repurchase program.

11. RENTALS AND LEASES

The company leases sales and administrative office facilities, distribution
center facilities, automobiles and computers and other equipment under operating
leases. Rental expense under all operating leases was $38,155,000 in 1997,
$35,071,000 in 1996 and $32,292,000 in 1995. As of December 31, 1997, future
minimum payments under operating leases with noncancelable terms in excess of
one year were:

12. RESEARCH EXPENDITURES

Research expenditures that related to the development of new products and
processes, including significant improvements and refinements to existing
products, were $30,420,000 in 1997, $28,676,000 in 1996 and $28,031,000 in 1995.

13. ENVIRONMENTAL COMPLIANCE COSTS

The company and certain subsidiaries are party to various environmental actions
that have arisen in the ordinary course of business. These include possible
obligations to investigate and mitigate the effects on the environment of the
disposal or release of certain chemical substances at various sites, such as
Superfund sites and other operating or closed facilities. The effect of these
actions on the company's financial position, results of operations and cash
flows to date has not been significant. The company is currently participating
in environmental assessments and remediation at a number of locations and
environmental liabilities have been accrued reflecting management's best
estimate of future costs. Potential insurance reimbursements are not
anticipated. While the final resolution of these contingencies could result in
expenses in excess of current accruals, and therefore have an impact on the
company's consolidated financial results in a future reporting period,
management believes the ultimate outcome will not have a significant effect on
the company's results of operations, consolidated financial position or
liquidity.

corporate level totaling $27,554,000 in 1997, $23,766,000 in 1996 and
$22,688,000 in 1995 have been allocated to the geographic segments in
determining operating income.

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, a new standard for reporting information
about operating or business segments in financial statements. The new standard
will be effective for the company's annual financial statements in 1998. The
company does not expect the business segment information reported under the new
standard to be substantially different than the information currently reported.

MANAGEMENT AND ACCOUNTANT'S REPORTS

REPORT OF MANAGEMENT

Management is responsible for the integrity and objectivity of the consolidated
financial statements. The statements have been prepared in accordance with
generally accepted accounting principles and, accordingly, include certain
amounts based on management's best estimates and judgments.

     To meet its responsibility, management has established and maintains a
system of internal controls that provides reasonable assurance regarding the
integrity and reliability of the financial statements and the protection of
assets from unauthorized use or disposition. These systems are supported by
qualified personnel, by an appropriate division of responsibilities and by an
internal audit function. There are limits inherent in any system of internal
controls since the cost of monitoring such systems should not exceed the desired
benefit. Management believes that the company's system of internal controls is
effective and provides an appropriate cost/benefit balance.

     The Board of Directors, acting through its Audit Committee composed solely
of outside directors, is responsible for determining that management fulfills
its responsibilities in the preparation of financial statements and maintains
financial control of operations. The Audit Committee recommends to the Board of
Directors the appointment of the company's independent accountants, subject to
ratification by the shareholders. It meets regularly with management, the
internal auditors and the independent accountants.

     The independent accountants provide an objective, independent review as to
management's discharge of its responsibilities insofar as they relate to the
fair presentation of the consolidated financial statements. Their report is
presented separately.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Directors
Ecolab Inc.

We have audited the accompanying consolidated balance sheet of Ecolab Inc. as of
December 31, 1997, 1996 and 1995, and the related consolidated statements of
income, shareholders' equity and cash flows for the years then ended. These
financial statements are the responsibility of the company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Ecolab Inc. as
of December 31, 1997, 1996 and 1995, and the consolidated results of its
operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

Pro forma results for 1994 and prior years reflect adjustments to eliminate
unusual items associated with Ecolab's merger with Kay Chemical Company in
December 1994. All per share, shares outstanding and market price data reflect
the 1997, 1993 and 1986 two-for-one stock splits. Other assets includes net
assets of Ecolab Europe and discontinued operations prior to 1992. Other
liabilities includes $110 million of convertible preferred stock at year-end
1989 and 1990. The ratios of return on beginning equity and dividends/diluted
net income per common share exclude the change in accounting principle and the
loss on the ChemLawn divestiture in 1991, and the Consumer gain in 1987. Number
of employees excludes ChemLawn operations.

Pro forma results for 1994 and prior years reflect adjustments to eliminate
unusual items associated with Ecolab's merger with Kay Chemical Company in
December 1994. All per share, shares outstanding and market price data reflect
the 1997, 1993 and 1986 two-for-one stock splits. Other assets includes net
assets of Ecolab Europe and discontinued operations prior to 1992. Other
liabilities includes $110 million of convertible preferred stock at year-end
1989 and 1990. The ratios of return on beginning equity and dividends/diluted
net income per common share exclude the change in accounting principle and the
loss on the ChemLawn divestiture in 1991, and the Consumer gain in 1987. Number
of employees excludes ChemLawn operations.
