FINANCIAL DISCUSSION

The following discussion and analysis provides information that management
believes is useful in understanding the company's operating results, cash flows
and financial condition. The discussion should be read in conjunction with the
consolidated financial statements and related notes.

     The financial discussion and other portions of this Annual Report to
Shareholders contain various "Forward-Looking Statements" within the meaning of
the Private Securities Litigation Reform Act of 1995. These statements, which
represent Ecolab's expectations or beliefs concerning various future events, are
based on current expectations that involve a number of risks and uncertainties
which could cause actual results to differ materially from those of such
Forward-Looking Statements. We refer readers to the company's statement entitled
"Forward-Looking Statements and Risk Factors" which is contained under Part I of
the company's Annual Report on Form 10-K for the year ended December 31, 1998.
Additional risk factors may be described from time to time in Ecolab's filings
with the Securities and Exchange Commission.

1998 OVERVIEW

During 1998, Ecolab achieved its seventh consecutive year of record financial
results and the company's stock outperformed the Standard & Poor's 500 index for
the fourth year in a row. The company's more significant accomplishments for
1998 included:

- -    Ecolab's stock price rose 31 percent during 1998 and, including dividends,
yielded a return of nearly 32 percent to shareholders.

                                    [GRAPH]

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

- -    Income from continuing operations rose 15 percent to a record $155 million,
or $1.15 per diluted share.

                                    [GRAPH]

- -    Return on beginning shareholders' equity reached a record 28 percent and
the company recorded its seventh consecutive year of exceeding its long-term
financial objective of a 20 percent return on beginning shareholders' equity.

- -    Cash provided by continuing operations increased 17 percent and also
reached an all-time high. Strong cash flow and moderate debt levels allowed the
company to maintain its long-term financial objective of an investment grade
balance sheet for the sixth consecutive year, and the company's debt continued
to be rated within the "A" categories by the major rating agencies.

- -    Net sales increased 15 percent and reached a record level of $1.9 billion.

- -    Operating income was a record $262 million for 1998 and increased 20
percent over the prior year. As a percent of net sales, operating income also
reached an all-time high of 13.9 percent.

- -    The company's equity in earnings of the Henkel-Ecolab joint venture rose 19
percent for 1998 to a record level.

- -    The company increased its annual dividend rate for the seventh consecutive
year. The annual dividend rate was increased 11 percent to an annual rate of
$0.42 per common share. The company has paid dividends on its common stock for
62 consecutive years.

- -    The company continued to make strategic business acquisitions in order to
broaden its product and service offerings in line with its Circle the
Customer -- Circle the Globe strategy. The integration of the Gibson business,
which was acquired at the end of 1997, was completed and the business exceeded
the company's expectations for 1998. Also during 1998, the company added
commercial kitchen equipment repair services to its operations through the
acquisition of GCS Service, Inc., and products and services were added to the
U.S. Institutional and Food & Beverage businesses and in Japan 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 6 of the notes to consolidated
financial statements.

     Consolidated net sales were nearly $1.9 billion for 1998, an increase of
15 percent over net sales of $1.6 billion in 1997. Both the company's United
States and International operations reported double-digit sales growth and
contributed to the consolidated sales improvement. Business acquisitions in
1998 and the annualized effect of businesses acquired in 1997 were
significant to the company's growth accounting for approximately one-half of
the overall sales growth for 1998. Changes in currency translation had a
negative effect on sales growth and decreased the consolidated growth rate by
three percentage points. The growth in sales also reflected the benefits of
new products, new customers, competitive gains, investments in the growth and
training of the sales-and-service force and a continuation of generally good
conditions in the hospitality and lodging industries, particularly in the
United States.

     Consolidated operating income reached $262 million for 1998, an increase
of 20 percent over operating income of $219 million in 1997. Business
acquisitions contributed to the growth in operating income and accounted for
approximately one-fifth of the increase. The consolidated operating income
margin rose to 13.9 percent for 1998 and surpassed 1997's operating income
margin of 13.3 percent to reach a new all-time high. A continuation of
particularly strong growth in the U.S. Institutional and Food & Beverage
operations and solid performances by the U.S. Pest Elimination and Kay
businesses were the major contributors to the company's overall profit
improvement. Operating income margin growth reflected lower selling, general
and administrative expenses as a percentage of net sales, partially offset by
a decrease in the gross profit margin from last year's all-time high.
Selling, general and administrative expenses were 41.0 percent of net sales
in 1998, a decease from 42.7 percent of net sales in 1997. Selling, general
and administrative expense margins were down for both the company's United
States and International operations with a significant decrease in the Asia
Pacific region. The improvement in the selling, general and administrative
expense margin reflected the benefits of tight cost controls, synergies from
the integration of businesses acquired, improved sales productivity and
strong sales growth. These benefits were partially offset by continued
investments in the training and growth of the sales-and-service force. The
gross profit margin was 54.9 percent of net sales for 1998, down slightly
from last year's record gross profit margin of 56.0 percent. The decrease in
gross profit margin reflected a comparison against an exceptionally strong
period last year, the effects of business acquisitions and lower margins in
the Asia Pacific region which was affected by economic and monetary problems.
These negative effects on the gross profit margin were partially offset by
the effects of sales of new products and good sales volume growth. Selling
price increases continued to be constrained due to competitive pricing
conditions in several of the markets in which the company does business.

     Income from continuing operations for 1998 rose 15 percent to $155 million,
or $1.15 per diluted share from $134 million, or $1.00 per diluted share in
1997. This improvement reflected double-digit growth in operating income and an
increase in the company's equity in earnings of the Henkel-Ecolab joint venture.
Earnings were negatively affected by increased net interest and income tax
expenses compared with last year. Income from continuing operations was 8.2
percent of net sales in both 1998 and 1997.


                                                                             25



     In addition to ongoing operations, a tax issue related to the disposal of a
business in 1992 was resolved during 1998, resulting in a one-time gain from
discontinued operations of $38 million, or $0.28 per diluted share. As a result
of tax losses on the disposition of this business, the company's U.S. federal
income tax payments were reduced in 1992 through 1995 by approximately $58
million. However, pending final acceptance of the company's treatment of the
losses, no income tax benefit was recognized for financial reporting purposes.
During 1998, an agreement was reached with the Internal Revenue Service on the
final tax treatment for the losses. This agreement resulted in the payment of
approximately $39 million of income taxes and interest, and the recognition of
the gain from discontinued operations.

     Net income for 1998 totaled $193 million, or $1.44 per diluted share,
compared with $134 million, or $1.00 per diluted share in 1997.

1997 COMPARED WITH 1996

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 accounted for approximately one-fourth of the growth in sales for
1997. New product introductions, a larger sales-and-service force, new customers
and competitive gains also added to the 1997 sales improvement.

     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. An improved and record level gross profit margin, reflecting good
sales volume growth and a more stable raw material cost environment, more than
offset a modestly higher selling, general and administrative expense margin and
limited selling price increases.

     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
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.

     During 1998, the company adopted Statement of Financial Accounting
Standards No. 131. As a result, the company defined its reportable segments and
changed the information it reports about its operating segments. Operating
segment information for prior years has been restated to conform to the 1998
presentation.

                                    [GRAPH]

     The company's operating segments have generally similar products and
services and, generally, the company is organized to manage its operations
geographically. Pursuant to the new standard, the company's operating segments
have been aggregated into three reportable segments: United States Cleaning and
Sanitizing operations, United States Other Services, and International Cleaning
and Sanitizing operations. The company evaluates the performance of its
International operations based on fixed management rates of currency exchange.
Therefore, International sales and operating income totals shown above, as well
as the International financial information included in this financial
discussion, are based on translation into U.S. dollars at the fixed currency
exchange rates used by management for 1998. All other accounting policies of the
reportable segments are consistent with generally accepted accounting principles
and the accounting policies of the company described in Note 2 of the notes to
consolidated financial statements. Additional information about the company's
reportable segments is included in Note 15 of the notes to consolidated
financial statements.

     Sales of the company's United States Cleaning and Sanitizing operations
were nearly $1.3 billion for 1998 and increased 12 percent over sales
approaching $1.2 billion in 1997. This sales increase reflected benefits from
business acquisitions, a continuation of particularly strong performances by the
company's core Institutional and Food & Beverage operations and double-digit
growth in sales reported by Kay. Business acquisitions accounted for
approximately 30 percent of the growth in sales of the United States Cleaning
and Sanitizing operations. Sales in 1998 also benefited from new product
introductions, new customers, competitive gains, a larger and better trained
sales-and-service force and favorable trends in the hospitality and lodging
industries. Selling price increases continued to be constrained due to
competitive pricing conditions in several of the markets in which the company
does business. Sales of the company's Institutional operations increased 11
percent for 1998. Institutional reported strong double-digit growth in its
Ecotemp, laundry, specialty and housekeeping programs and solid growth in sales
to warewashing markets. Institutional benefited from new customers, competitive
gains, high customer retention and the addition of the Grace-Lee vehicle wash
business, which added approximately 2 percentage points to the Institutional
sales growth rate. Kay's U.S. operations reported sales growth of 10 percent for
1998 reflecting new business, continued growth in its food retail services
business and retention of key customers. Textile Care sales increased 1 percent
for 1998. Textile Care has a number of new product offerings, but continues to
experience pressures from consolidations in the commercial laundry market and a
difficult pricing environment. The company expects the U.S. Textile Care
business to continue to experience challenging market conditions over the near
term. Professional Products sales were up 6 percent, with double-digit growth in
its specialty and brand name program and infection prevention products, and
modest growth in its core janitorial business. Sales of the company's Water Care
operations increased 6 percent for 1998, reflecting double-digit growth in its
pool and spa and cruise ship businesses, partially offset by lower distributor
sales to municipal markets. Food & Beverage reported sales growth of 15 percent
for 1998. Food & Beverage sales growth included the benefits of businesses
acquired in 1998 and the annualized effect of last year's acquisition of
Chemidyne. Excluding the effect of these business acquisitions, Food & Beverage
sales increased 8 percent and included strong growth in sales to the beverage
and food processing markets and good growth in sales to the dairy markets,
despite challenging consolidation and pricing conditions.

     For 1998, sales of the company's United States Other Services operations
increased 34 percent to $160 million, compared with $119 million last year.
Sales for 1998 included the mid-year acquisition of GCS Service Inc. (GCS), a
nationwide provider of commercial kitchen equipment repair services. Other


                                                                             27



Services sales grew 14 percent excluding the GCS business acquisition. Pest
Elimination reported sales growth of 14 percent for 1998 with strong sales
across all of its business lines, including its core contract services business,
its flying insect defense program and ancillary services. Pest Elimination had
very good new contract growth during 1998, continued its high customer retention
and benefited from weather conditions that contributed to greater pest
elimination needs during 1998. Sales of the Jackson equipment business increased
18 percent for 1998, reflecting good sales to the quickservice or fast-food
market.

                                    [GRAPH]

     Management rate sales of the company's International Cleaning and
Sanitizing operations were $441 million for 1998, up 31 percent over sales of
$335 million in 1997. Sales in 1998 benefited from the acquisition of Gibson at
the end of 1997 and from the addition of a business in Japan during 1998. These
business acquisitions accounted for approximately two-thirds of International's
sales growth for 1998. The Asia Pacific region, International's largest area of
operation, reported sales growth of 56 percent. Excluding business acquisitions,
Asia Pacific sales increased approximately 10 percent and reflected double-digit
growth in Japan and Southeast Asia, modest growth in Australia and a decrease in
sales in New Zealand. Sales to the Asia Pacific food and beverage markets were
up significantly and the region recorded modest growth in sales to institutional
markets. Latin America sales for 1998 increased 8 percent over the prior year.
The region continued to be led by significant double-digit growth in Mexico.
Sales were also up at double-digit rates in Venezuela and in Central America,
while sales growth in Brazil was modest. Latin America recorded good growth in
sales to both the institutional and food and beverage markets. Sales in Canada
increased 9 percent for 1998 and included high single-digit growth in sales to
both the institutional and food and beverage markets. Sales for the company's
operations in Africa decreased 6 percent for 1998 as the company focused on
integrating the various businesses acquired over the last couple of years.

     Operating income of the company's United States Cleaning and Sanitizing
operations was $219 million in 1998, an increase of 21 percent over operating
income of $181 million in 1997. Business acquisitions accounted for
approximately 10 percent of the growth in operating income for 1998. Operating
income growth in the core Institutional and Food & Beverage businesses remained
very strong and operating income in the Kay and Professional Products businesses
was also up at double-digit rates. Textile Care and Water Care reported a
decrease in operating income for 1998. The operating income margin for the U.S.
Cleaning and Sanitizing operations improved to 16.8 percent of net sales,
compared with 15.6 percent in 1997. The increased operating income margin
reflected strong sales growth, including a continuation of strong performance in
the core operations and in sales of new products, modest increases in raw
material costs and the benefits of tight cost controls. The company continued to
invest in its sales-and-service force during 1998 and added 255 associates to
its U.S. Cleaning and Sanitizing operations.

     United States Other Services reported an increase of 30 percent in
operating income, to $19 million in 1998 from $15 million in the prior year.
Excluding the GCS acquisition, operating income was up 27 percent. The operating
income margin was down slightly, to 11.9 percent of net sales in 1998 from 12.3
percent last year, due in part to the addition of GCS. The increase in operating
income for 1998 was driven by sales growth, productivity improvements and tight
cost controls. 365 sales-and-service associates were added to the U.S. Other
Services operations in 1998, including GCS associates.

     International Cleaning and Sanitizing operations reported operating
income of $30 million for 1998, an increase of 32 percent over 1997 operating
income of $23 million. Business acquisitions accounted for approximately 90
percent of the growth in operating income for 1998. Operating income margins
for the International Cleaning and Sanitizing operations were 6.8 percent of
net sales in 1998 compared with 6.7 percent in the prior year. Operating
income reflected significant double-digit growth in Latin America, good
growth in Canada and a decrease in operating income in Africa and in the Asia
Pacific region when the Gibson acquisition is excluded. The company continues
to be cautious about near-term growth in Asia Pacific due to the lingering
uncertain economic conditions in the region. The recent currency devaluation
in Brazil is also expected to slow growth in Latin America during 1999. The
company added 300 sales-and-service associates to its International Cleaning
and Sanitizing operations during 1998, including associates of businesses
acquired.

     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, technical support
and administrative personnel are also necessary in order to facilitate growth of
International operations.

1997 COMPARED WITH 1996

Sales of the company's United States Cleaning and Sanitizing operations
approached $1.2 billion in 1997 and increased 11 percent over sales of $1.0
billion in 1996. Sales reflected strong growth in the core Institutional and
Food & Beverage operations and included benefits from business acquisitions
and significant new product introductions. Business acquisitions accounted
for approximately 25 percent of the 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. 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 food
retail market, which it entered in 1996. Sales of Textile Care 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. Professional Products
reported sales growth of 12 percent for 1997. This sales improvement
reflected the annualized effect of the 1996 acquisition of Huntington
Laboratories, good growth in sales to corporate accounts, and the addition of
new products to its commercial mass distribution line. Water Care sales 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.
Food & Beverage reported a sales increase of 24 percent for 1997. Food &
Beverage sales growth included the benefits ofChemidyne, a provider of
cleaning and sanitizing products and equipment to the meat, poultry and
processed food markets, which was acquired in August of 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.

     Sales of the United States Other Services operations were $119 million for
1997, up 10 percent over sales of $108 million in 1996. Pest Elimination
reported 10 percent sales growth for 1997, despite increased competitive
activity. Pest Elimination continued to develop new programs to leverage its
alliances with Ecolab's other operations. Sales of the Jackson business
increased 18 percent for 1997.

     International Cleaning and Sanitizing sales were $335 million for 1997 and
increased 10 percent over sales of $306 million in 1996. Sales growth included
the 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. Asia Pacific had sales growth of 9
percent for 1997 with double-digit growth in Japan, modest growth in New Zealand
and flat results in Australia. Latin America reported sales growth of 9 percent
for 1997. Growth in the Latin America region was led by significant double-digit
growth in Mexico and included good growth in Brazil. Canada had sales growth of
16 percent for 1997, with approximately 70 percent of its growth due to business
acquisitions. International sales results also benefited from businesses
acquired in Central Africa during 1997. Sales in South Africa decreased during
1997, principally due to the elimination of low margin business.

     Operating income of the United States Cleaning and Sanitizing operations
reached $181 million in 1997, an increase of 18 percent over operating income of
$153 million in 1996. Business acquisitions accounted for approximately 20
percent of operating income growth for 1997. With the exception of Textile Care,
all of the company's U.S. Cleaning and Sanitizing operations


                                                                             29



reported increased operating income, with particularly strong growth in the
core Institutional and Food & Beverage operations. The U.S. Cleaning and
Sanitizing operating income margin improved to 15.6 percent of net sales from
14.7 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.

     United States Other Services operating income was $15 million for 1997, up
23 percent over operating income of $12 million in 1996. The operating income
margin improved from 11.0 percent of net sales in 1996 to 12.3 percent of net
sales in 1997. The improvement in operating income reflected strong sales,
productivity improvements and tight cost controls.

     Operating income of the company's International Cleaning and Sanitizing
operations totaled $23 million in 1997, an increase of 18 percent over operating
income of $19 million in 1996. Operating income margins improved to 6.7 percent
of net sales in 1997 compared with 6.3 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.

HENKEL-ECOLAB JOINT VENTURE

The company operates cleaning and sanitizing businesses in Europe through a 50
percent economic interest in the Henkel-Ecolab joint venture. The company
includes the operations of Henkel-Ecolab in its financial statements using the
equity method of accounting. The company's equity in earnings of Henkel-Ecolab,
including royalty income and after deduction of intangible amortization, was $16
million in 1998, a 19 percent increase over 1997. When measured in Deutsche
marks, net income of Henkel-Ecolab increased 18 percent for 1998. This
improvement reflected increased sales, the benefits of cost controls and a lower
overall effective income tax rate.

                                    [GRAPH]

     Henkel-Ecolab sales, although not consolidated in Ecolab's financial
statements, increased 10 percent when measured in Deutsche marks. Excluding
businesses acquired in the United Kingdom and Germany, sales increased 5 percent
for 1998 with good growth across most divisions and regions. Sales in Germany
continued to be weak due in part to government and private spending cutbacks.
When measured in U.S. dollars, Henkel-Ecolab sales were up 7 percent for 1998.

1997 COMPARED WITH 1996

The company's equity in earnings of Henkel-Ecolab was $13 million for 1997, a 3
percent increase over 1996. Results were negatively affected by the stronger
U.S. dollar. When measured in Deutsche marks, Henkel-Ecolab's net income
increased 11 percent and reflected increased sales, improved gross margins and
lower interest expense. Henkel-Ecolab sales increased 7 percent when measured in
Deutsche marks. When measured in U.S. dollars, sales were negatively affected by
the strengthening U.S. dollar and decreased 7 percent.

CORPORATE

Corporate operating expense was $4 million in 1998 and 1997 and $3 million in
1996. Corporate operating expense includes overhead costs directly related to
the joint venture.

INTEREST AND INCOME TAXES

Net interest expense for 1998 was $22 million, an increase of 72 percent over
net interest expense of $13 million in 1997. This increase was due to debt
incurred at the end of 1997 for the Gibson business acquisition and for
additional borrowings related to other business acquisitions, income tax
payments to settle an outstanding tax issue and share repurchases during 1998.

     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's effective income tax rate was 42.4 percent for 1998, and
increased from an effective income tax rate of 41.5 percent in 1997. This
increase was principally due to a higher overall effective rate on earnings of
International operations and to the effects of business acquisitions.
International's effective


30



income tax rate varies from year to year with the pre-tax income mix of the
various countries in which the company operates.

     The company's 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.

YEAR 2000 CONVERSION

The company has completed an assessment of Year 2000 compliance for its critical
operating and application systems located at its St. Paul-based headquarters.
These include customer-oriented systems such as sales and order processing,
billing and collections and associated infrastructure. As a result, the company
has remediated or is replacing portions of its software and hardware. The
company has tested these systems by simulating the occurrence of the Year 2000
in an orchestrated manner. Approximately 95 percent of the systems proved
compliant and the goal is to complete the remaining renovation and testing by
July 1999. The costs related to complete this activity are not expected to
exceed $7.0 million, in both capital and expense, of which approximately $5.5
million has been incurred to date. The company does not consider these costs to
be material to results of operations, financial position, or liquidity.

     Each business unit not on the St. Paul system is responsible for developing
and implementing a Year 2000 compliance plan for its critical operating and
application systems (including assessment, remediation, validation and
implementation) subject to the oversight and coordination of a special
corporate-wide Year 2000 management team. The goal was for these business units
to complete all compliance activities by December 31, 1998. The business units
have reported approximately 90 percent achievement of Year 2000 compliance.
Where compliance has not been achieved, appropriate remedial plans have been
adopted. The Year 2000 management team is currently auditing the plans as
presented by the business units to ensure corporate-wide consistency in these
efforts and, to the extent determined necessary, will participate in tests based
on the simulation of Year 2000. The goal is to achieve full compliance by July
1999.

     The company has completed an assessment of its dispensing and cleaning
systems which are at customer locations, for date/time sensitivity. The
installed base of such cleaning and dispensing systems which has not been
determined to be Year 2000 compliant is estimated at less than 0.5 percent of
all systems in place at customer sites. The company believes that Year 2000
compliant alternatives have been designed and identified and that the systems
can be retrofitted by July 1999.

     The company has completed the assessment stage of analyzing its
manufacturing and building maintenance operations for date/time sensitivity
relative to Year 2000. While some issues have been identified, the company
believes that it can modify its processes or retrofit equipment to become Year
2000 compliant and is in the process of doing so with the intention of
completing the process by July 1999.

     The company does not have final estimates for the costs of full Year 2000
remediation other than for St. Paul-based operating and application systems but
it believes the costs, when aggregated with costs for the St. Paul-based
systems, will not be material to the company's results of operations, financial
position, or liquidity. The costs will be funded by operating cash flows.

     The company intends to complete its Year 2000 remediation efforts primarily
with in-house resources, but has and will continue to use consultants for
specific tasks.

     Failures caused by the Year 2000 of key suppliers and vendors could cause
supply interruptions. Therefore, the company has contacted key suppliers and
vendors in order to determine the status of their Year 2000 remediation plans.
In the company's experience, its key suppliers and vendors are aware of the Year
2000 issue and represent that they have plans for being compliant on a timely
basis. The company intends to continue to monitor progress and may take further
actions to verify the accuracy of vendor and supplier representations.

     The company is dependent upon its customers for sales and cash flow and
customers' Year 2000 failures could result in reduced sales, increased inventory
or receivable levels and cash flow reductions. While these events are possible,
the company's customer base is wide and diverse and the company does not, at
this point, believe that customers' Year 2000 failures will have a material
effect on the company. The company will continue to monitor this issue and will
consider further actions as may be warranted in the circumstances.

     The company recognizes the need for Year 2000 contingency plans and will be
developing such plans during 1999.

     The Henkel-Ecolab joint venture is conducting its own Year 2000 compliance
program.

     The company recognizes that issues related to Year 2000 constitute a
material known uncertainty. The company also recognizes the importance of
ensuring its operations will not be adversely affected by Year 2000 issues. It
believes that the processes described above will be effective to manage the
risks


                                                                             31



associated with Year 2000 compliance. However, there can be no assurance that
the process can be completed on the timetable described above, that it will
be 100 percent effective in identifying all Year 2000 issues, or that the
remediation processes for its own operations will be completely effective.
The issues related to vendors or suppliers are more difficult because their
Year 2000 compliance programs are not within the company's direct control.
These uncertainties relating to Year 2000, however, are ones which the
company believes it shares with companies in similar businesses. Additional
information is found under the company's statement entitled "Forward-Looking
Statements and Risk Factors" which is contained under Part I of the company's
Annual Report on Form 10-K for the year ended December 31, 1998.

     The failure to identify and remediate Year 2000 problems or, the failure of
key third parties who do business with the company or governmental/regulatory
agencies to timely remediate their Year 2000 issues could cause system failures
or errors, business interruptions and in a worst case scenario, the inability to
engage in normal business practices for an unknown length of time. Litigation
could also ensue. The effect on the company's results of operations, financial
position, or liquidity could be materially adverse.

EURO CURRENCY CONVERSION

The company's principal activities in Europe are not conducted directly. Rather,
such activities are conducted through its Henkel-Ecolab joint venture.

     On January 1, 1999, 11 of the 15 member countries of the European Monetary
Union established fixed conversion rates between their existing currencies and a
new currency, the Euro. During a transition period from January 1, 1999 through
January 1, 2002, the Euro will replace the national currencies that exist in the
participating countries.

     The transition to the Euro creates a number of sales, marketing, finance
and accounting issues. These issues are being addressed by the management of the
Henkel-Ecolab joint venture.

     While the company will continue to evaluate the impact of the Euro
introduction over time, based on currently available information and the nature
of the company's exposures, the company does not, at this time, believe that the
transition to the Euro will have a material adverse impact on the company's
results of operations, financial position, or liquidity.

FINANCIAL POSITION, CASH FLOWS AND LIQUIDITY

FINANCIAL POSITION

The company has maintained its long-term financial objective of an investment
grade balance sheet since 1993. The company's debt was rated within the "A"
categories by the major rating agencies throughout 1998. Significant changes to
the company's balance sheet during 1998 included the following:

- -    The company has added assets and liabilities to its balance sheet during
the last two years through business acquisitions. Other noncurrent assets
reflect significant additions for the GCS business and a cleaning and sanitizing
business acquired in Japan during 1998, and the acquisitions of Gibson and
Chemidyne in 1997. Significant levels of accounts receivable, inventories,
property, plant and equipment and other current liabilities were also added
during 1998 and 1997 as a result of these business acquisitions. During 1998,
net assets (principally accounts receivable, inventories and property, plant and
equipment) related to certain Gibson businesses and duplicate facilities were
reclassified to other current assets and the majority of these net assets were
sold.

                                    [GRAPH]

- -    Total debt was $295 million at December 31, 1998, compared with total
debt of $308 million at year-end 1997 and $176 million at year-end 1996. 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.
During 1998, the company replaced long-term debt under its Multicurrency
Credit Agreement with approximately $60 million of
Australian-dollar-denominated debt under a medium-term note agreement and
approximately $30 million of Australian-dollar-denominated commercial paper.
At December 31, 1998, the company had $44 million of U.S.-dollar-denominated
debt outstanding


32



under its Multicurrency Credit Agreement related primarily to business
acquisitions, funding for income tax payments to settle an outstanding tax
issue and share repurchases. As of December 31, 1998, the ratio of total debt
to capitalization was 30 percent compared to 36 percent at year-end 1997 and
25 percent at year-end 1996. The improvement in the total debt to
capitalization ratio for 1998 was principally due to increased shareholders'
equity, which resulted from strong earnings performance and the 1998 gain
from discontinued operations.

- -    Working capital levels have remained fairly constant over the last three
year ends. Working capital was $104 million at year-end 1998, compared with
working capital levels of $105 million and $108 million at year-end 1997 and
1996, respectively.

- -    Other noncurrent liabilities decreased to $68 million at December 31, 1998
from $125 million at year-end 1997 and $138 million at year-end 1996. During
1998, the company resolved a tax issue related to the disposal of a business in
1992. As a result, the company reduced its noncurrent liabilities through the
payment of income taxes of approximately $39 million and the recognition of a
gain from discontinued operations of $38 million.

CASH FLOWS

For 1998, cash flows from continuing operating activities reached a record $275
million, compared to $235 million in 1997 and $254 million in 1996. Operating
cash flows for 1998 included strong earnings performance and the additional cash
flows from businesses acquired. Operating cash flows for 1997 were unfavorably
affected by a cash outflow due to an $18 million income tax deposit against
outstanding federal income tax issues that had been accrued for in other
noncurrent liabilities, and the reversal of favorable timing of payments which
affected the fourth quarter of 1996. Operating cash flows for 1997 also included
higher dividends from the Henkel-Ecolab joint venture.

     Cash used for discontinued operating activities in 1998 reflects income
taxes paid related to a business which was discontinued in 1992.

     CASH USED FOR DISCONTINUED OPERATING ACTIVITIES IN 1998 REFLECTS


                                    [GRAPH]

     Cash flows used for investing activities included capital expenditures of
$148 million in 1998, $122 million in 1997 and $112 million in 1996. 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 also expanded its manufacturing facilities over
the last few years through construction and business acquisitions in order to
meet sales requirements more efficiently. The majority of cash flows used in
1998 for businesses acquired were related to the year-end 1997 Gibson
acquisition and a cleaning and sanitizing business acquired in Japan in early
1998. Cash flows used for businesses acquired included Gibson in 1997 and
Huntington and Monarch in 1996. Investing activities cash flows for 1998 also
included the proceeds from the sale of certain Gibson businesses and duplicate
facilities which the company chose not to retain.

     Cash used for financing activities included cash flows used for reacquired
shares, cash dividends and net cash used of $9 million to reduce short-term and
long-term debt during 1998.

     In 1998, the company increased its annual dividend rate for the seventh
consecutive year. The company has paid dividends on its common stock for 62
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
          Quarter   Quarter      Quarter      Quarter      Year

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 additional source of
liquidity. The company believes its existing cash balances, cash generated by
operating activities, including cash flows from the Henkel-Ecolab joint venture,
available credit, and additional credit available based on a strong financial
position, are more than adequate to fund all of its 1999 requirements for
growth, possible acquisitions, new program investments, scheduled debt
repayments and dividend payments.


                                                                             33

                                                   Ecolab 1998 Annual Report 37



NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

ONE: NATURE OF BUSINESS

The company is the leading global developer and marketer of premium cleaning
and sanitizing 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.

TWO: 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 accumulated other
comprehensive income in shareholders' equity.

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 45 percent, 40 percent and 44 percent of consolidated
inventories at year-end 1998, 1997 and 1996, 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.

INCOME PER COMMON SHARE

The computations of the basic and diluted per share amounts for the company's
continuing operations were as follows:



(thousands, except per share)            1998           1997           1996

          Diluted                $       1.15   $       1.00   $       0.85


     Stock options granted in 1998 for approximately 2.2 million shares were not
dilutive and, therefore, were not included in the computation of diluted income
per common share amounts for 1998.

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.

     The company has a $275 million Multicurrency Credit Agreement with a
consortium of banks. The company may borrow varying amounts from time to time on
a revolving credit basis, with loans denominated in G-7 currencies, Australian
dollars 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 1998 were denominated in U.S.
dollars and had an average annual interest rate of 6.7 percent and amounts
outstanding at year-end 1997 were denominated in Australian dollars and had an
average annual interest rate of 5.2 percent.

     In August 1998, the company issued approximately $60 million of
Australian-dollar-denominated medium-term notes that mature in November 2001.
The company also issued approximately $30 million of
Australian-dollar-denominated commercial paper (notes payable). The proceeds
from these debt issuances were used to reduce debt under the company's
Multicurrency Credit Agreement.

     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.

     As of December 31, the weighted-average interest rate on notes payable was
7.4 percent for 1998, 5.4 percent for 1997 and 5.1 percent for 1996.

     As of December 31, 1998, the aggregate annual maturities of long-term debt
for the next five years were: 1999 - $15,550,000; 2000 - $15,714,000; 2001 - 
$77,799,000; 2002 - $45,820,000 and 2003 - $10,374,000.

     Interest expense was $25,012,000 in 1998, $18,043,000 in 1997 and
$19,084,000 in 1996. Total interest paid was $25,198,000 in 1998, $18,168,000 in
1997 and $16,897,000 in 1996.

     Other noncurrent liabilities included income taxes payable of $30 million
at December 31, 1998, $82 million at December 31, 1997 and $100 million at
December 31, 1996. During 1998, the company resolved a tax issue related to the
disposal of a business in 1992. The company paid approximately $39 million and
recognized a gain from discontinued operations of $38 million related to the
settlement of this issue.



                                                                             39


FOUR: FINANCIAL INSTRUMENTS

FOREIGN CURRENCY AND INTEREST RATE 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 related to intercompany debt,
Henkel-Ecolab and subsidiary royalties and other intercompany 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.

     The company had foreign currency forward exchange contracts with a face
amount denominated primarily in Deutsche marks and totaling approximately $71
million at December 31, 1998, $70 million at December 31, 1997 and $115 million
at December 31, 1996. The unrealized gains and losses on these contracts were
not significant.

     At December 31, 1998, the company had entered into an interest rate swap
agreement which is effective November 2001 through November 2004. This agreement
provides for a fixed rate of interest on an amount equal to one-half of the debt
under the company's medium-term notes. The fair value of the company's interest
rate swap agreement was not significant as of December 31, 1998.

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

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

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, a new standard of accounting and
reporting for derivative instruments and hedging activities. The company is
required to adopt the new standard in the first quarter of 2000. Although a full
analysis of all of the requirements of the new standard has not been completed,
the company's use of derivative and hedging financial instruments is limited
and, therefore, the company does not anticipate that the impact of the new
standard will be significant.

FIVE: GAIN FROM DISCONTINUED OPERATIONS

During the third quarter of 1998, the company resolved a tax issue related to
the disposal of a business in 1992. As a result of tax losses on the disposition
of this business, the company's U.S. federal income tax payments were reduced in
1992 through 1995 by a total of approximately $58 million. However, pending
final acceptance of the company's treatment of the losses, no income tax benefit
was recognized for financial reporting purposes. During 1998, an agreement was
reached with the Internal Revenue Service on the final tax treatment for the
losses. This agreement resulted in the payment of approximately $39 million of
income taxes and interest, and the recognition of a gain from discontinued
operations of $38 million or $0.28 per diluted share for the year ended December
31, 1998.


SIX: BUSINESS ACQUISITIONS

GIBSON BUSINESS ACQUISITION

During 1997, the company completed 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.

     The acquisition was accounted for as a purchase. The purchase price of the
shares and the direct costs of the transaction totaled approximately $130
million and were initially financed through the company's Multicurrency Credit
Agreement. The excess of the purchase price over the net tangible assets
acquired was approximately $88 million and is being amortized on a straight-line
basis over useful lives averaging 25 years. The assets acquired and the
liabilities assumed in the transaction were included in the company's
Consolidated Balance Sheet as of the November 30, 1997 effective date.

     The following unaudited pro forma financial information reflects the
combined results of the company and the retained Gibson businesses assuming the
acquisition had occurred at the beginning of 1997. Pro forma adjustments have
been included to

give effect to amortization of the excess of the purchase price over the net
tangible assets acquired, interest expense on debt incurred to finance the
acquisition and the related income tax effects. In accordance with the pro
forma adjustment guidelines, cost savings from efficiencies and synergies
have not been reflected in the information shown below.

     The pro forma results are presented for information purposes only and are
not necessarily indicative of the results of operations which actually would
have resulted had the combination occurred at the beginning of 1997 or of future
results of operations of the consolidated businesses.

OTHER BUSINESS ACQUISITIONS

In December 1997, the company acquired a cleaning and sanitizing business in
Japan from Henkel KGaA. Sales of the acquired business were approximately $10
million in 1997.

     In June 1998, the company acquired certain assets of American Fluid
Technologies (AFT), which is based in Hopkins, Minnesota. AFT provides cleaning
and optimization products and services for membrane systems used to process
water for food, beverage, pharmaceutical and industrial applications. AFT has
become part of the company's Food & Beverage operations. AFT sales were
approximately $3 million in 1997.

     Also in June 1998, the company acquired certain assets of Puremark
International, a Fairfield, New Jersey-based manufacturer of systems which help
purify and condition water used in foodservice soda fountain dispensers, ice
makers, coffee makers and similar items. The acquired business had sales of
approximately $2 million in 1997, and has become part of the company's
Institutional operations.

     In July 1998, the company issued approximately 850,000 shares of common
stock to purchase GCS Service, Inc., a Danbury, Connecticut-based provider of
commercial kitchen equipment repair services. GCS Service, Inc. sales were $48
million in 1997.

     In November 1998, the company acquired selected assets of Vulcan Chemical
Technologies, Inc. of Sacramento, California. This business supplies chlorine
dioxide generator technology for the food processing industry and has become
part of the company's Food & Beverage operations. Annual sales of the business
acquired were approximately $6 million in 1997.

     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 to the company's consolidated results of
operations, financial position and cash flows.

     Cash paid for income taxes was approximately $122 million in 1998, $100
million in 1997 and $72 million in 1996. In 1998, approximately $39 million of
payments resulted from the settlement of a tax issue related to the disposal of
a business in 1992.

     As of December 31, 1998, undistributed earnings of international
subsidiaries and the Henkel-Ecolab joint venture of approximately $30 million
and $50 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.

NINE: 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 1,835,714 for 1998, 5,274,652 for 1997 and 840,096 for 1996.

     Options may be granted to purchase shares of the company's stock at not

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

     The company measures compensation cost for its stock incentive and option
plans using the intrinsic value-based method of accounting.

     Had the company used the fair value-based method of accounting to measure
compensation expense for its stock incentive and option 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, income from continuing
operations and the related diluted per common share amounts for 1998, 1997 and
1996 would have been reduced to the following pro forma amounts:

TEN: SHAREHOLDERS' EQUITY

During 1998, the company adopted Statement of Financial Accounting Standards No.
130, a new standard for reporting comprehensive income, which includes all
changes in shareholders' equity with the exception of additional investments by
shareholders or distributions to shareholders. The format of the Consolidated
Statement of Comprehensive Income and Shareholders' Equity has been changed to
present information about comprehensive income. For the company, comprehensive
income includes net income and foreign currency translation that is charged or
credited to 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 Comprehensive Income and Shareholders' Equity.

     Authorized common stock, par value $1.00 per share, was 200 million shares
in 1998 and 1997 and 100 million shares in 1996. Treasury stock is stated at
cost. Dividends declared per share of common stock were $0.39 for 1998, $0.335
for 1997 and $0.29 for 1996.

     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.



                                                                             43


TEN: SHAREHOLDERS' EQUITY (CONTINUED)

     The company maintains a share repurchase program which is intended to 
offset the dilutive effect of shares issued for employee benefit plans. The 
company also reacquires shares for general corporate purposes under a 
separate program established in 1995. As of December 31, 1998 there were 
approximately 3.6 million shares remaining to be purchased under this 
program. The company reacquired 1,626,900 shares of its common stock in 1998, 
2,561,400 shares in 1997 and 1,260,400 shares in 1996 under these programs 
through open and private market purchases. The company anticipates that it 
will continue to periodically reacquire shares under its share repurchase 
programs.

ELEVEN: 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 $42,076,000 in 1998,
$38,155,000 in 1997 and $35,071,000 in 1996. As of December 31, 1998, future
minimum payments under operating leases with noncancelable terms in excess of
one year were:

Total                                           $     49,863


TWELVE: RESEARCH EXPENDITURES

Research expenditures that related to the development of new products and
processes, including significant improvements and refinements to existing
products, were $32,815,000 in 1998, $30,420,000 in 1997 and $28,676,000 in 1996.

THIRTEEN: 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 different than 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 consolidated results of operations, financial position or
liquidity.

FOURTEEN: RETIREMENT 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.

     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.

     For postretirement benefit measurement purposes, 8.5 percent (for pre-age
65 retirees) and 6.9 percent (for post-age 65 retirees) annual rates of increase
in the per capita cost of covered health care were assumed for 1999. 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.

     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 $12 million at December 31, 1998 and the annual expense for 
these plans was approximately $3 million in 1998 and approximately $2 million 
in 1997 and 1996. 

     Assumed health care cost trend rates have a significant effect on the 
amounts reported for the company's postretirement health care benefits plan. 
A one-percentage point change in the assumed health care cost trend rates 
would have the following effects:

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 $7,383,000 in 1998, $7,156,000 in 1997 and
$6,622,000 in 1996.

FIFTEEN: OPERATING SEGMENTS

During 1998, the company adopted Statement of Financial Accounting Standards No.
131. The new standard changes the information the company reports about its
operating segments. Operating segment information for prior years has been
restated to conform to the 1998 presentation.

     The company's operating segments have generally similar products and
services and the company is organized to manage its operations geographically.
The company's operating segments have been aggregated into three reportable
segments.

     The "United States Cleaning & Sanitizing" segment provides cleaning and
sanitizing products and services to United States markets through its
Institutional, Kay, Textile Care, Professional Products, Water Care and Food &
Beverage operations.

     The "United States Other Services" segment includes all other U.S.
operations of the company. This segment provides pest elimination and commercial
dishwashing and equipment services through its Pest Elimination, GCS Service and
Jackson operations.

     The company's "International Cleaning & Sanitizing" segment provides
cleaning and sanitizing product and service offerings to international markets
in Asia Pacific, Latin America, Africa, Canada and through its Export
operations.

     Information on the customers, markets and products and services of each of
the company's operating segments is included on the inside front cover, in the
Business Overview section of this Annual Report.

     The company evaluates the performance of its international operations based
on fixed management currency exchange rates. All other accounting policies of
the reportable segments are consistent with generally accepted accounting
principles and the accounting policies of the company described in Note 2 of
these notes to consolidated financial statements. The profitability of the
company's operating segments is evaluated by management based on operating
income. Intersegment sales and transfers were not significant.

MANAGEMENTS AND ACCOUNTANTS' 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.

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, comprehensive income and shareholders' equity
and cash flows present fairly, in all material respects, the financial position
of Ecolab Inc. as of December 31, 1998, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles. 
These financial statements are the responsibility of Ecolab Inc.'s management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.
