                                     PART I

ITEM 1.  BUSINESS

ITEM 1(A) GENERAL DEVELOPMENT OF BUSINESS

Except where the context otherwise requires, the terms "Company" and "Ecolab,"
as used herein, include Ecolab Inc. and its subsidiaries.  Ecolab Inc. was
incorporated as a Delaware corporation in 1924.  The Company's fiscal year is
the calendar year ending December 31.

The Company and Henkel KGaA of Dusseldorf, Germany, each have a 50% economic
interest in a joint venture which operates institutional and industrial cleaning
and sanitizing businesses in Europe, and which is referred to hereafter as the
"Henkel-Ecolab Joint Venture" or "Joint Venture."  Henkel KGaA, by virtue of a
tie-breaking vote on certain operational matters, may control the day-to-day
operations of the Joint Venture.  Strategic decisions concerning the Joint
Venture require the agreement of Henkel and the Company.  The Company accounts
for its interest in the Henkel-Ecolab Joint Venture under the equity method of
accounting and therefore does not consolidate the Henkel-Ecolab Joint Venture
revenues and expenses.  Except where the Henkel-Ecolab Joint Venture is
specifically referred to, the description of business in Part I does not include
the business of the Joint Venture.

ITEM 1(B) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The Company's operations are all conducted in one industry segment.

ITEM 1(C) NARRATIVE DESCRIPTION OF BUSINESS

The Company is engaged in the development and marketing of premium products and
services for the hospitality, institutional and industrial markets.  The Company
provides cleaning, sanitizing, pest elimination and maintenance products,
systems and services primarily to hotels and restaurants, foodservice,
healthcare and educational facilities, commercial and institutional laundries, 

                                      - 2 -

<PAGE>

light industry, dairy plants and farms, and food and beverage processors.

A strong commitment to service is the distinguishing characteristic of the
Company.  Products, systems and services are primarily marketed in domestic and
international markets by Company-trained sales and service personnel who also
advise and assist customers in the proper and efficient use of the products and
systems.  Distributors are utilized in several markets.

The Company manufactures most of its products and related equipment in
Company-owned manufacturing facilities.  Some are also produced for the Company
by third party contract manufacturers.  Other products and equipment,
particularly those used in the Company's Pest Elimination business, are
purchased from third party suppliers.  Additional information on the Company's
manufacturing facilities is located under Item 2 below under the heading
"Properties."

As described below, not all of the businesses conducted in the United States and
Canada by the Company are conducted in all other international locations, and
the extent and nature of such international businesses, as well as the
competitive environment, varies by location.  European markets, as described
under Item 1(a) above under the heading "General Development of Business," are
served through the Henkel-Ecolab Joint Venture, although the Kay business does
have sales in Europe.

In the United States and Canada, the Company operates through seven divisions: 
Institutional, Kay, Food and Beverage (formerly Klenzade), Pest Elimination,
Textile Care, Janitorial and Water Care Services.  Institutional and Food and
Beverage businesses are operated in virtually all locations outside of the
United States and Canada.  As described below, the businesses of the remaining
divisions are not conducted in all areas outside of the United States and
Canada, but these businesses are being introduced in an expanding number of
international locations.  

The Company conducts business in approximately 26 countries outside of the
United States, primarily through wholly-owned subsidiaries.  In certain other
countries, selected products are sold by distributors or agents, although those
sales are not significant in terms of the Company's overall revenues.  For the
year ended December 31, 1995, international sales comprised approximately 23% of
the Company's total reported revenues.  For purposes of public financial
reporting, international operations include Canada, but on an operational basis
the businesses in Canada are generally operated as a part of North American
operations.

                                      - 3 -

BUSINESS DIVISIONS

The following descriptions of the Company's divisions include a discussion,
where applicable, of the similar business currently conducted outside of the
United States.  The Company pursues a "Circle the Customer - Circle the Globe"
strategy by developing relationships and partnerships with customers who require
the services of more than one division.  Therefore, a single customer may
utilize the services of several of the Company's divisions.

INSTITUTIONAL:  The Institutional Division is the Company's largest division and
sells specialized cleaners and sanitizers for washing dishes, glassware,
flatware, food service utensils and kitchen equipment ("warewashing"), for
on-premise laundries (typically used by customers having smaller machines and
laundry needs) and for general housekeeping functions, as well as dishwasher
racks and related kitchen sundries to the food-service, lodging, educational and
healthcare industries.  The Institutional Division also markets various chemical
dispensing device systems, which are generally loaned to customers, to apply the
Company's cleaners and sanitizers.  Substantially similar businesses are
conducted in all international locations although somewhat less extensive
product lines are often offered internationally.  Also, through its Ecotemp
offering, the Institutional Division markets, primarily to smaller and mid-size
customer units, a program comprised of energy-efficient dishwashing machines,
detergents and rinse additives, including full machine maintenance.  

The Company believes it is the leading supplier of chemical warewashing products
to institutions in the United States and Canada and is one of the leading
suppliers worldwide except for Europe where the business is conducted by the
Henkel-Ecolab Joint Venture.  

The Institutional Division sells its products and services primarily through
Company-employed field sales and service personnel.  The Company also utilizes
independent food service distributors to market and sell its products to smaller
accounts or accounts which purchase through food distributors.  This
distribution system encompasses most of the Division's product line and the
Company provides the same service to accounts served by food distributors as to
direct customers.  

KAY:  The Kay Division was acquired in December, 1994 and is operated through
wholly-owned subsidiaries of the Company.  Kay supplies chemical cleaning and
sanitizing products primarily to the quick-service restaurant ("fast-food")
industry.  Kay's products include specialty and general purpose hard surface
cleaners, degreasers, sanitizers, polishes and hand care products and assorted
cleaning tools.  Products are sold under the "Kay" brand or the customer's
private label.  Kay employs a direct field sales force which primarily calls
upon national and regional quick service restaurant chains and franchisees,
although the sales are

                                      - 4 -

<PAGE>

made to distributors who supply the chain or franchisee's restaurants.  The
addition of the Kay business has significantly expanded the Company's presence
in the restaurant and food service industry beyond the full service market to
the quick-service industry. 

Kay sales are primarily in the United States but international sales have grown
as United States based customers have expanded into international markets.  With
minor exceptions for product made at international locations by contract
manufacturers, Kay's international sales are made either to domestic
distributors, who export to international accounts, or by export sales to
distributors located at international locations.

The Company believes that its Kay Division is the leading supplier of chemical
cleaning and sanitizing products to the quick-service industry in the United
States as well as in certain international markets.  While the Kay customer base
has been growing, Kay's business is largely dependent upon a limited number of
major national and international quick-service restaurant chains and
franchisees.

FOOD AND BEVERAGE:  The Food and Beverage Division (formerly known as Klenzade)
provides detergents, cleaners, sanitizers, lubricants, animal health and water
treatment products, as well as cleaning systems, electronic dispensers and
chemical injectors for the application of chemical products, primarily to dairy
plants, dairy, poultry and swine farms, breweries, soft drink bottling plants,
and meat, poultry and other food processors as well as to pharmaceutical and
cosmetic plants.  The Food and Beverage Division also designs, engineers and
installs CIP (clean-in-place) process control systems and facility cleaning
systems to its customer base.  Farm products (which include bovine teat
products) are sold through dealers and distributors, while plant products are
sold primarily by the Company's field sales personnel.  The Company believes
that it is one of the leading suppliers of cleaning and sanitizing products to
the dairy plant, dairy farm and beverage processor industries in the United
States.  The Food and Beverage business operates in most international
locations.

PEST ELIMINATION:  The Pest Elimination Division provides services for the
elimination and prevention of pests to restaurants, food and beverage
processors, educational and healthcare facilities, hotels and other
institutional and commercial customers.  These services are sold and performed
by Company-employed sales and service personnel.  The Company believes it is the
largest provider of premium pest elimination services to institutions in the
United States.  The Pest Elimination business currently is operated primarily in
the United States, with limited sales in Puerto Rico and parts of Canada,
Mexico, Hong Kong and New Zealand.  

                                      - 5 -

<PAGE>


TEXTILE CARE:  The Textile Care Division provides chemical laundry products and
proprietary dispensing systems, as well as related services, to large
institutional and commercial laundries and to certain smaller laundry
operations.  Typically these customers process a minimum of 1,000,000 pounds of
linen each year.  These products and services include laundry cleaning and
specialty products and related dispensing equipment, which are marketed
primarily through a Company-employed sales force and, to a lesser extent,
through distributors.  The Textile Care offerings compliment the Institutional
Division's offerings to small-to-medium size on-premise laundry facilities.  The
Textile Care products are sold primarily in the United States and Canada, but
similar product lines are sold in a number of other international locations.

JANITORIAL:  The Janitorial Division provides a full line of janitorial
offerings that includes odor counteractants, disinfectants, floor care or hard
surface and carpet care systems, hand care products and general cleaners which
are sold to both the industrial and institutional janitorial market in the
United States and Canada.  The Company believes it is the largest supplier of
infection control and general cleaners to the United States healthcare industry.
Products are sold in the United States and Canada through a Company-employed
sales force as well as a network of independent distributors who sell
janitorial-related products and services to the institutional and industrial
marketplaces.  A private-label program also manufactures non-proprietary
janitorial-related products for resale by major distributor organizations in the
United States and Canada.  Janitorial products are also sold on a limited basis
in other international markets.

WATER CARE SERVICES:  The Water Care Services Division provides water treatment
products, services and systems for institutional, commercial and light
industrial customers.  Operations are presently concentrated in North America,
where the Company acquired three existing water care businesses in late 1994 and
1995.  Water Care Services works closely with the Company's Institutional,
Textile Care and Food and Beverage Divisions to offer customized water care
strategies to the hospitality, healthcare markets and to light industry,
primarily to treat water used for heating and cooling systems.  In selected
United States markets, the Division also provides pool and spa treatment
programs for commercial and hospitality customers.  Water Care Services expects
to expand its coverage in North America during 1996 through additional
acquisitions and internal growth.  In addition to North America operations,
certain water treatment businesses are operated at selected international
locations, primarily Brazil, South Africa and Southeast Asia.

COMPETITION

The Company emphasizes its ability to uniformly provide a variety of related
premium cleaning and sanitation services to multiple locations of chain customer
organizations worldwide.  This is succinctly stated in the Company's "Circle the
Customer - Circle the Globe" strategy.  In executing this strategy, the
Company's business units have two significant classes of competitors.  First,
each business unit competes with a small number of large companies selling
directly or through distributors on a national or international scale.  Some of
these large competitors have substantially greater assets and financial
resources than the Company.  Second, all of the Company's business units have
numerous smaller regional or local competitors focusing on more limited
geographies, product lines, and/or end-user segments.

The Company's objective is to achieve a significant presence in each of its
business markets.  In general, competition is based on service, product
performance and price.  The Company believes it  competes principally by
providing superior value.  Value is provided by state-of-the-art,
environmentally-compatible cleaning products and systems coupled with high
service standards and dedication to customer satisfaction after the initial
sale.  This is made possible, in part, by the significant ongoing investment in
technology development and by the Company's standard practice of assisting
customers in lowering operating costs and complying with environmental and
sanitation regulations.

RAW MATERIALS

Raw materials purchased for use in manufacturing products for the Company are
inorganic chemicals, including phosphates, silicates, alkalies, salts and
petrochemical-based materials, including surfactants and solvents.  These
materials are generally purchased on an annual contract basis from a diverse
group of chemical manufacturers.  Pesticides used by the Pest Elimination
Division are purchased as finished products under contract or purchase order
from the producers or their distributors.  The Company also purchases packaging
materials for its manufactured products and components for its specialized
cleaning equipment and systems.  Most raw materials, or substitutes for those
materials, used by the Company, with the exception of a few specialized
chemicals which the Company manufactures, are available from several suppliers.

ADDITIONAL INFORMATION

Deliveries to customers are made from the Company's manufacturing plants and a
network of distribution centers and public warehouses.  The Company uses both
common carriers and its own delivery vehicles.  Additional information on the
Company's plant and distribution facilities is located under Item 2 below under
the heading "Properties."

                                      - 7 -

<PAGE>

The Company owns a number of patents and trademarks.  Management does not
believe that the Company's overall business is materially dependent on any
individual patent or trademark.

The Company believes that its business is not materially dependent upon a single
customer although, as described above in this Item 1(c) under the description of
the Kay business, Kay is largely dependent upon a limited number of national and
international quick-service chains and franchisees.  No material part of the
Company's business is subject to renegotiation.  The Company sells two classes
of products which each constitute 10 percent or more of its sales.  Worldwide
sales of warewashing products in 1995, 1994 and 1993 approximated 35, 35 and 36
percent, respectively, of the Company's consolidated net sales.  In addition,
the Company, through its Institutional and Textile Care businesses, sells
laundry products and services to a broad range of laundry customers as described
in more detail under the heading "Business Divisions" beginning on page 4
hereof.  Total laundry sales in each of 1995, 1994 and 1993 approximated 15
percent of the Company's consolidated net sales.

The Company's business has little seasonality and has no unusual working capital
requirements.  The Company has in the past, and will continue in the future, to
invest in merchandising equipment consisting primarily of systems used by
customers to dispense the Company's cleaning and sanitizing products.  The
investment in merchandising equipment is discussed under the heading "Cash
Flows" in Management's Discussion and Analysis of Financial Condition and
Results of Operations incorporated into Item 7 hereof.  

RESEARCH AND DEVELOPMENT

The Company's research and development program consists principally of devising
or testing new products, processes, techniques and equipment, improving the
efficiency of existing ones, improving service program content, and evaluating
the environmental compatibility of products.  Key disciplines include analytical
and formulation chemistry, microbiology, process and packaging engineering and
product dispensing technology.  Substantially all of the Company's principal
products have been developed by its research and development personnel.  Note
12, entitled "Research Expenditures" located on page 43 of the Annual Report, is
incorporated herein by reference.

ENVIRONMENTAL CONSIDERATIONS

The Company's businesses are subject to various legislative enactments and
regulations relating to the protection of the environment.  While the Company
cooperates with governmental authorities and takes commercially practicable
measures to meet regulatory requirements and avoid or limit environmental
effects,

                                      - 8 -

<PAGE>

some risks are inherent in the Company's businesses.  The Company's management
believes these are risks which the Company has in common with other companies
engaged in similar businesses.  Among the risks are costs associated with
managing hazardous substances, waste disposal or plant site clean-up, fines and
penalties if the Company were found in violation of law, as well as
modifications, disruptions or discontinuation of certain operations or types of
operations.  There can be no assurance that future legislation or enforcement
policies will not have a material adverse effect on the Company's financial
condition or results of operations.  Environmental matters most significant to
the Company are discussed below.

PHOSPHATE LEGISLATION:  Various laws and regulations have been enacted by state,
local and foreign jurisdictions pertaining to the sale of products which contain
phosphorous.  The primary thrust of such laws and regulations is to regulate the
phosphorous content of home laundry detergents, a market not served by the
Company.  However, certain of the Company's products are affected by such laws
and regulations, including some commercial laundry and warewashing detergents,
cleaners and sanitizers.  Three types of legislative restrictions are common: 
(1) labeling of phosphorous content, (2) percentage limitation on the amount of
phosphorous permitted and (3) a ban on the use of phosphorous in certain
products or in products sold for a particular purpose.  The Company has been
able to comply with legislative requirements and, where necessary, has developed
products which, although typically less effective than the products they
replace, contain no phosphorous or lower amounts of phosphorous to satisfy the
legislative limitations or bans.  In limited geographic areas, the Company has
obtained a variance from existing zero-phosphorous legislation.  Phosphate
legislation has not had a material negative effect on the Company's operations
to date.

PESTICIDE LEGISLATION:  Various federal and state environmental laws and
regulations govern the manufacture and/or use of pesticides.  The Company
manufactures and sells certain disinfecting and sanitizing products which kill
microorganisms (bacteria, viruses, fungi) on environmental surfaces.  Such
products constitute "pesticides" under the current definitions of the Federal
Insecticide Fungicide and Rodenticide Act (FIFRA), the principal federal statute
governing the manufacture, labeling, handling and use of pesticides.  These
products must be registered with the United States Environmental Protection
Agency ("EPA").  Registration entails the necessity to meet certain efficacy and
labeling requirements and to pay initial and on-going registration fees.  In
addition, each state in which these products are sold requires registration and
payment of a fee.  In general, the states impose no substantive requirements
different from those required by FIFRA.  However, California does have its own
regulatory scheme and

                                      - 9 -

<PAGE>

certain other states have regulatory schemes under consideration.  In addition,
California imposes a tax on total pesticide sales in that state.  While the
costs of complying with rules as to pesticides has not had a material adverse
effect on the Company's financial condition or the results of its operations to
date, the costs and delays in receiving necessary approvals for these products
has increased in recent years.  The Company believes that the nature of these
costs and regulatory delays are similar to those encountered by other companies
in similar businesses.  Total fees paid to the EPA and the states to obtain or
maintain pesticide registrations, and for the California tax, in 1995 were
approximately $876,000.  Such costs may increase somewhat in 1996, but not in
amounts which are expected to significantly affect the Company's results of
operations, consolidated financial condition or liquidity.

In addition, the Company's Pest Elimination Division applies restricted-use
pesticides which it purchases from third parties.  That Division must comply
with certain standards pertaining to the use of such pesticides and to the
licensing of employees who apply such pesticides.  Such regulations are enforced
primarily by the states or local jurisdictions in conformity with federal
regulations.  The Company has not experienced material difficulties in complying
with these requirements.  

OTHER ENVIRONMENTAL LEGISLATION:  The Company's manufacturing plants are subject
to federal, state, local or foreign jurisdiction laws and regulations relating
to discharge of hazardous substances into the environment and to the
transportation, handling and disposal of such substances.  The primary federal
statutes that apply to the Company's activities are the Clean Air Act, the Clean
Water Act and the Resource Conservation and Recovery Act ("RCRA").  The Company
makes capital investments and expenditures to comply with environmental laws and
regulations, to ensure employee safety and to carry out its announced
environmental stewardship principles.  To date such expenditures have not had a
significant adverse effect on the financial condition of the Company or its
results of operations.  The Company's capital expenditures for environmental
control projects incurred for 1995 and budgeted for 1996 are approximately
$900,000 and $300,000, respectively.  The Company is also subject to the
Superfund Amendments and Reauthorization Act of 1986, which imposes certain
reporting requirements as to emissions of toxic substances into the air, land
and water.

Along with numerous other potentially responsible parties ("PRPs"), the Company
is currently involved with waste disposal site clean-up activities imposed by
the federal Comprehensive Environmental Response Compensation and Liability Act
("CERCLA") or state equivalents at 12 waste disposal sites which received
nominal amounts of waste materials alleged to have been generated by the Company
or its subsidiaries.  In general, under CERCLA, the Company

                                     - 10 -

<PAGE>

and each other PRP which actually contributes hazardous substances to a
superfund site are jointly and severally liable for the costs associated with
cleaning up the site.  Customarily, the PRP's will work with the EPA to agree
and implement a plan for site remediation and the allocation of each PRP's
involvement.  The above sites are in various stages of investigation,
negotiation or remediation.  However, based on an analysis of the Company's
experience with such sites, the Company's estimated share of all hazardous
materials deposited on the site, and the Company's estimate of the contribution
to be made by other PRP's which the Company believes have the financial ability
to pay their shares, the Company has accrued its reasonable estimate of the
Company's future costs relating to such known sites.

Also, the Company is involved in certain continuing clean-up activities as
required by New Jersey and Nebraska environmental authorities at two sites
currently or formerly used by the Company.  The costs associated with these
sites are comprised primarily of remediation efforts associated with soil and
ground water contamination.  In each of these matters, the Company has worked
with appropriate authorities to resolve the issues involved and has accrued its
reasonable estimate of future costs relating to such sites.

A legal action commenced in August, 1989 in the District Court in Zwolle,
Netherlands, by the Netherlands government against a former subsidiary of the
Company remains pending.  Netherlands authorities are seeking monetary damages
to cover the cost of investigation and planned cleanup of soil and groundwater
contamination, allegedly resulting from the discharge of wastewater and
chemicals during a period ended in 1981 when the subsidiary operated a plant on
the site.  Damages claimed are approximately US$10,000,000.  The former 
subsidiary, now owned by the Henkel-Ecolab joint venture, has denied liability
and believes it complied with applicable Netherlands law.  Even if the
Netherlands government should prevail as to liability, it is believed the
reasonable costs of investigation and cleanup are less than that claimed by the
government.  The Company has indemnified the Henkel-Ecolab joint venture as to
any liability associated with this matter.  Accordingly, an accrual has been
recorded, reflecting management's best estimate of future costs.  

During 1995, the Company's expenditures for contamination remediation were
approximately $500,000.  The accrual at the end of 1995 for future remediation
expenditures was approximately $8,500,000.  The Company reviews its exposure for
contamination remediation costs periodically and its accruals are adjusted as
considered appropriate.  In establishing accruals, the Company does not
anticipate recovery of costs from insurance proceeds.  While the final
resolution of these issues could result in costs below or above current
accruals, the Company believes the ultimate resolution of these matters will not
have a significant effect on

                                     - 11 -

<PAGE>

the Company's results of operations, consolidated financial position or
liquidity.

In addition, the Company has retained responsibility for certain sites where the
Company's former ChemLawn business is a PRP.  Currently there are nine such
locations and at each, ChemLawn is a de minimus party.  Anticipated costs
currently accrued for these matters were included in the Company's loss from its
discontinued ChemLawn operations in 1991.

NUMBER OF EMPLOYEES

The Company currently has approximately 9,000 employees worldwide.

The financial information appearing under the heading "Geographic Segments" in
Note 14, located on page 43 of the Annual Report, is incorporated herein by
reference.  Transfers between geographic areas are not significant.

A description of the business done outside of the United States is included in
Item 1(c), above.  International businesses are subject to the usual risks of
foreign operations, including possible changes in trade and foreign investment
laws, tax laws, currency exchange rates and economic and political conditions
abroad.  International operations constitute the fastest growing segment of the
Company's business.  Profitability of international operations is lower than
profitability of businesses in the United States because of lower international
operating income margins due to the difference in scale of international
operations where operating locations are smaller in size and due to the
additional costs of operating in numerous and diverse foreign jurisdictions.

EXECUTIVE OFFICERS OF THE COMPANY

The persons listed in the following table are the current executive officers of
the Company.  Officers are elected annually.  There is no family relationship
among any of the directors or executive officers, and none of such persons has
been involved during the past five years in any legal proceedings described in
applicable Securities and Exchange Commission regulations.

              REPORT OF INDEPENDENT ACCOUNTANTS



The Board of Directors
Henkel-Ecolab Joint Venture


We have audited the combined financial statements of Henkel-Ecolab Joint Venture
as listed in the accompanying index. In connection with our audit of the
combined financial statements, we also have audited the financial statement
schedule as listed in the accompanying index. These combined financial
statements and financial statement schedule are the responsibility of the Joint
Venture's management. Our responsibility is to express an opinion on these
combined financial statements and financial statement schedule based on our
audits.

We conducted our audits in accordance with German generally accepted auditing
standards which in all material respects are similar to auditing standards
generally accepted in the United States. 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.

                                      - 2 -

In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of the Henkel-Ecolab
Joint Venture as of November 30, 1995, 1994 and 1993, and the results of its
operations and its cash flows for the periods beginning December 1, 1994, 1993
and 1992, and ended November 30, 1995, 1994 and 1993, in conformity with
accounting principles generally accepted in the United States. Also in our
opinion, the related financial statement schedule, when considered in relation
to the basic combined financial statements taken as a whole, presents fairly, in
all material respects, the information set forth therein.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

On July 1, 1991, Henkel KGaA (Henkel) and Ecolab, Inc. (Ecolab) formed a 
joint venture of their respective European institutional and industrial 
hygiene businesses.

Under the terms of the Amended and Restated Joint Venture Agreement dated 
June 26, 1991 (Joint Venture Agreement), Henkel and Ecolab have joint control 
over the activities of the Joint Venture. The Joint Venture Agreement also 
provides that both partners will share an equal economic interest in the 
profits or losses of the Joint Venture.

The financial statements are presented on a combined basis as each Joint 
Venture entity is owned beneficially by identical shareholders or their 
wholly-owned subsidiaries. All significant intercompany or affiliated company 
accounts and transactions have been eliminated in combination. The Joint 
Venture's fiscal year end has been designated as November 30.

The financial statements are presented on the basis of generally accepted 
accounting principles in the United States.

FOREIGN CURRENCY TRANSLATION

The accounts of all foreign subsidiaries and affiliates are generally 
measured using the local currency as the functional currency, except for one 
country, where due to hyperinflation the functional currency since 1994 has 
been changed to DEM. For those operations, assets and liabilities are 
translated into German Marks at period-end exchange rates. Income statement 
accounts are translated at the average rates of exchange prevailing during 
the period. Net exchange gains or losses resulting from such translation are 
excluded from net earnings and accumulated in a separate component of 
combined equity. Gains and losses from foreign currency transactions are 
included in the related income statement category.

The Joint Venture enters into foreign currency forward contracts and options 
to hedge specific foreign currency exposures. Gains and losses on these 
contracts are deferred and recognized as part of the specific transaction 
hedged or included in other expenses, principally interest expense, net. The 
cash flows from such contracts are classified in the same category as the 
transaction hedged in the Combined Statement of Cash Flows.

CASH EQUIVALENTS

Cash equivalents are highly liquid investments with a maturity of three 
months or less when purchased. Interest income for the period totalled TDM 
3,494 in 1995, TDM 3,877 in 1994 and TDM 4,976 in 1993.

INVENTORIES

Inventories are stated at the lower of cost or market. The method of 
determining cost varies between the First-in First-out method, and the 
average cost method.

INVESTMENT IN AFFILIATED COMPANY

Investment in the common stock of one affiliated company is accounted for by 
the equity method. The excess of cost of this affiliate over the Company's 
share of its net assets at the acquisition date is being amortized on a 
straight-line basis over 10 years.

The investment in an affiliated company consists of 33 percent of the common 
stock of Comac SpA, Verona. The unamortized portion of the excess of cost 
over the Joint Venture's share of net assets of Comac amounts to TDM 4,696 at 
November 30, 1995, TDM 5,444 at November 30, 1994 and TDM 6,192 at November 
30, 1993. The market value of the investment cannot be determined.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at original cost. Merchandise 
equipment consists primarily of various systems for dispensing cleaning and 
sanitizing products. Depreciation and amortization are charged to operations 
using the straight-line and declining balance methods over the following 
estimated useful lives:

Building and improvements                   8 to 40 years
Machinery and equipment                     3 to 20 years
Furniture, fixtures and equipment           3 to 16 years

Leasehold improvements are amortized over a period which is the lesser of the 
useful life of the asset or the remaining term of the associated lease. 
Betterments, renewals and extraordinary repairs that extend the life of the 
asset are capitalized; other repairs and maintenance are expensed. The cost 
and accumulated depreciation applicable to the assets retired are removed 
from the accounts and any gain or loss credited or charged to income.

INTANGIBLE ASSETS

Intangible assets primarily consist of amounts by which cost of acquisitions 
exceed the values assigned to net tangible assets. These assets are amortized 
over their estimated lives, periods from 3 to 15 years. Total amortization of 
all intangible assets amounted to TDM 7,469, TDM 6,407 in 1994 and TDM 4,283 
in 1993.

3.  RELATED PARTY TRANSACTIONS

The Joint Venture has entered into a variety of contractual arrangements, 
including those discussed in the following paragraphs for the supply of 
products, the performance of general and administrative services and the 
transfer of technology.

Certain Joint Venture entities purchase institutional and industrial hygiene 
products (primarily finished goods inventory) from Henkel and its 
subsidiaries under a variety of supply agreements. The terms of these 
agreements require these entities to purchase specified quantities as defined 
by an annual supply plan submitted to the related manufacturing facility. 
Since 1995 products are purchased at agreed upon prices between the parties 
involved, prior to that on the basis of costs incurred. Purchases totalled 
TDM 239,819 in 1995, TDM 259,882 in 1994 and TDM 278,693 in 1993.

Henkel also provides certain Joint Venture entities with elective services 
which include, but are not limited to General Administration, Payroll 
Administration, Accounting, Research and Development. The cost of services 
are charged by Henkel on a monthly basis and may not reflect the costs which 
the Joint Venture would incur if it were necessary to procure such services 
from outside sources or if such services were performed internally by the 
Joint Venture. Fees paid by the Joint Venture in consideration for these 
services amounted to TDM 20,365 in 1995, TDM 20,326 in 1994 and TDM 23,353 in 
1993.

Royalty payments are shared equally by both parent companies based upon a 
technology transfer agreement which provides for the payment of royalties as 
a percentage of third party sales. Royalty expense related to this technology 
transfer agreement amounted to TDM 28,180 in 1995, TDM 31,874 in 1994 and TDM 
36,460 in 1993.

The Joint Venture has entered into agreements with Henkel under which the 
Joint Venture can both borrow from and lend to Henkel both on an over-draft 
basis and through short term loans of more than 3 months. There is currently 
no maximum level of borrowing specified under this agreement. The interest 
rate basis for both arrangements is the London Interbank Offering Rate 
(interest rate for German marks overdrafts 5.25 % per November 30, 1995 and 
4.25 % for 3 month short term German Marks loans per November 30, 1995); on 
overdrafts, approximately between 0.4 - 1.5 percentage point is paid to 
compensate Henkel for administration costs.

At November 30, 1995 the Joint Venture had borrowed TDM 48,437, from Henkel 
Group Companies, TDM 63,810 in 1994 and TDM 75,910 in 1993. The loans 
received from Henkel Group Companies had totalled TDM 15,778 in 1995, TDM 
38,140 in 1994 and TDM 12,297 in 1993. The fair values of intercompany loans 
receivable and payable approximate book value.

Interest expense to related companies totalled TDM 6,235 in the year ended 
November 30, 1995, TDM 6,304 in 1994 and TDM 9,819 in 1993. Interest income 
from related companies amounted to TDM 3,251 for the year ended November 30, 
1995, TDM 1,989 in 1994 and TDM 1,503 in 1993.

4.  INCOME TAXES

The provision for income taxes totalled TDM 31,637, compared to November 30, 
1994 TDM 36,287 and November 30, 1993 TDM 35,966. The net deferred taxes 
included in the provision for income taxes for 1995 were TDM 624 credit, for 
1994 TDM 1,993 credit and for 1993 TDM 2,770 credit.

Effective December 1, 1992, the Joint Venture adopted the provisions of 
Statement of Financial Accounting Standards of Nov. 109, "Accounting for 
Income Taxes" (FAS 109). The cumulative effect of this change in accounting 
principle as of December 1, 1992 amounted to TDM 9,771. Prior years' 
financial statements were not restated.

The components of the Joint Venture's overall net deferred tax asset at 
November 30, 1995, at November 30, 1994 and at November 30, 1993 are as 
follows:

16,577. A significant portion of these losses have an indefinite carryforward 
period; the remaining losses have expiration dates up to five years.

<PAGE>

As of November 30, 1995, 1994 and 1993 the tax benefits of the loss 
carryforwards have been reserved 100% in Great Britain, 20% in Italy, 60% in 
Switzerland in 1995 and 80% in 1994 and 1993. As at December 1, 1992 all loss 
carryforwards had been reserved 100%. The changes in the valuation allowance 
were made due to turnarounds in the profitability of the Joint Venture 
companies in the respective countries.

In assessing the realizability of deferred tax assets, management considers 
whether it is more likely than not that some portion or all of the deferred 
tax assets will not be realized. The ultimate realization of deferred tax 
assets is dependent upon the generation of future taxable income during the 
periods in which those temporary differences become deductible. Management 
considers the scheduled reversal of deferred tax liabilities, projected 
future taxable income, and tax planning strategies in making this assessment. 
Based upon the level of historical taxable income and projections for future 
taxable income over the periods which the deferred tax assets are deductible, 
management believes it is more likely than not the Joint Venture will realize 
the benefits of these deductible differences, net of the existing valuation 
allowances at November 30, 1995.

income tax rate to the effective income tax rate was:

The deferred taxes refundable to parent reflect the Joint Venture Agreement 
in which the partners also agreed that all tax benefits realized after the 
formation of the Joint Venture should be refunded to the respective parents 
if the benefits relate to temporary differences that originated in periods 
prior to the formation of the Joint Venture. The amount refundable in 1993 
covers the period from July 1, 1991 to November 30, 1993.

In 1995, the tax payments were TDM 24,503, in 1994 TDM 21,368 and in 1993 TDM 
29,846.

5.  RETIREMENT PLANS

The Joint Venture's German entities have noncontributory defined benefit 
pension plans to provide pension benefits to substantially all eligible 
employees. Employees of countries outside of Germany participate in various 
local plans, principally contributory plans.

Benefits for the German plans are based upon salary and years of service. The 
funding of these pension plans is not a common practice as funding provides 
no economic (tax) benefit.

A summary of the components of net periodic pension cost for the German plans 
for the twelve months ended November 30, 1995, 1994 and 1993 follows (TDM):

The Joint Venture also sponsors other defined benefit plans, defined 
contribution plans and participation government-sponsored programs in certain 
European countries. Expenses under these plans amounted to approximately TDM 
7,767 for the twelve months ended November 30, 1995, TDM 13,433 in 1994 and 
TDM 12,863 in 1993.

Other Joint Venture-specific savings plans, post-retirement and 
post-employment benefit plans requiring contribution by the Joint Venture are 
not material.

November 30, 1994 TDM 19,256 and compared to November 30, 1993 TDM 45,505, 
generally in overdraft facilities with interest rates based on local money 
market rates. As of November 30, 1995 the three main balances are in French 
Franc in the equivalent amount of TDM 7,599 at an interest rate of 6.5 %-7 % 
p.a., in Italian Lira in the equivalent amount of TDM 3,291 at an interest 
rate of 11 % p.a. and in Spanish Peseta in the equivalent amount of TDM 
2,458 at an interest rate of 7.15 % p.a..

The total long term debt amount is borrowed in Danish Krona at an average 
interest rate of 10.18 % p.a.. As of November 30, 1995, the aggregate annual 
maturities of long term debt for the next five years were:

1996 - TDM 712                      1997 - TDM   645
1998 - TDM 645                      1999 - TDM   645
2000 - TDM 645                after 2000 - TDM 3,325

Interest expense related to all debt was TDM 4,329 in 1995, compared to 
November 30, 1994 TDM 4,584 and compared to November 30, 1993 TDM 6,700. No 
significant differences existed between interest expense and interest paid.

The fair value of short and long term debt approximates the book value.

7.  FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

The Joint Venture operates internationally, giving rise to exposure to market 
risks from changes in interest rates and foreign exchange rates. Derivative 
financial instruments are utilized by the Joint Venture to reduce certain of 
these risks, as explained in this note. The Joint Venture does not hold or 
issue financial instruments for trading purposes. The Joint Venture is 
exposed to credit-related losses in the event of nonperformance by 
counterparties to financial instruments, but it does not expect any 
counterparties to fail to meet their obligations given their high credit 
ratings.

a) Notional Amounts and Credit Exposures of Derivatives

The notional amounts of derivatives summarized in section b) do not represent 
amounts exchanged by the parties and, thus, are not a measure of the 
exposure of the Joint Venture through its use of derivatives. The amounts 
exchanged are calculated on the basis of the notional amounts and the other 
terms of the derivatives, which relate to exchange rates.

b) Foreign Exchange Risk Management

The Joint Venture enters into various types of foreign exchange contracts in 
managing its foreign exchange risk, as indicated in the following table (TDM):

                                November 30, 1995         November 30, 1994

                                ------       -            ------       ---

The primary purpose of foreign exchange contracts is to hedge various 
intercompany loans. The Joint Venture also enters to a limited extent into 
forward exchange contracts and options to hedge certain existing and 
anticipated future net foreign exchange exposures. The anticipated future 
foreign exchange exposure of the Joint Venture is the total of the net 
balances of all known and planned incoming and outgoing payments of the Joint 
Venture's companies in foreign currencies during a 12 months time horizon. 
Gains and losses arising on hedged loan transactions are accrued to income 
over the period of the hedge.

The table below summarizes by major currency the contractual amounts of the 
Joint Venture's forward exchange and option contracts in German Marks. 
Foreign currency amounts are translated at rates current at the reporting 
date. 

The "buy" amounts represent the German Marks equivalent of commitments to 
purchase foreign currencies, and the "sell" amounts represent the German 
Marks equivalent of commitments to sell foreign currencies (TDM):

9.  COMMITMENTS AND CONTINGENCIES

The Joint Venture has a number of operating lease agreements primarily 
involving motor vehicles, computer and other office equipment. The following 
is a schedule by year of the future minimum lease payments required under the 
operating leases that have initial or remaining noncancellable lease terms in 
excess of one year as of November 30, 1995 (TDM):

                    1996                   14,943
                    1997                    9,119
                    1998                    5,839
                    1999                    4,513
                    2000                    4,069
                    thereafter              5,362
                                           ------
                    Total                  43,845
                                           ------
                                           ------

Rent expense for the twelve month period ended November 30, 1995, was 
approximately TDM 17,790, compared to November 30, 1994 approximately TDM 
16,372 and compared to November 30, 1993 approximately TDM 13,415.

The Joint Venture is subject to lawsuits and claims arising out of the 
conduct of its business, including those relating to commercial transactions 
and environmental safety. As an integral part of the Joint Venture 
agreement, Henkel and Ecolab have provided certain representations and 
warranties against future expenditures arising from operations prior to July 
1, 1991.

A subsidiary of the Joint Venture is named in an environmental legal action 
related to the conduct of its business prior to the formation of the Joint 
Venture on July 1, 1991. Based on the facts currently known to the Joint 
Venture, and after consultation with Legal Counsel, management believes that 
the Joint Venture is indemnified against any potential liability arising from 
such action under the terms and conditions of the Amended and Restated 
Umbrella Agreement dated June 26, 1991, by and between Henkel and Ecolab.

Therefore, the Joint Venture does not expect material adverse effects on its 
financial position, results of operations or liquidity from the outcome of

The Joint Venture's operations and customers are located throughout in Europe 
and operate in the industrial and institutional hygiene business. No single 
customer accounted for a significant amount of the Joint Venture's sales in 
1995, 1994 and 1993, and there were no significant accounts receivable from a 
single customer at November 30, 1995, 1994 and 1993. The Joint Venture 
establishes an allowance for doubtful accounts based upon factors surrounding 
the credit risk of specific customers, historical trends and other 
information.

     of all non-cash dividends or other distributions other than a dividend
     payable in shares of Common Stock or a subdivision of the outstanding
     shares of Common Stock (by reclassification or otherwise), declared on the
     Common Stock, par value $1.00 per share, of the Corporation (the "Common
     Stock") since the immediately preceding Quarterly Dividend Payment Date,
     or, with respect to the first Quarterly Dividend Payment Date, since the
     first issuance of any share or fraction of a share of Series A Junior
     Participating Preferred Stock.  In the event the Corporation shall at any
     time after February 24, 1996 (the "Rights Declaration Date") (i) declare
     any dividend on Common Stock payable in shares of Common Stock, (ii)
     subdivide the outstanding Common Stock, or (iii) combine the outstanding
     Common Stock into a smaller number of shares, then in each such case the
     amount to which holders of shares of Series A Junior Participating
     Preferred Stock were entitled immediately prior to such event under clause
     (b) of the preceding sentence shall be adjusted by multiplying such amount
     by a fraction the numerator of which is the number of shares of Common
     Stock outstanding immediately after such event and the denominator of which
     is the number of shares of Common Stock that were outstanding immediately
     prior to such event.

          (B)  The Corporation shall declare a dividend or distribution on the
     Series A Junior Participating Preferred Stock as provided in paragraph (A)
     above immediately after it declares

                                        2

<PAGE>

     a dividend or distribution on the Common Stock (other than a dividend
     payable in shares of Common Stock); provided that, in the event no dividend
     or distribution shall have been declared on the Common Stock during the
     period between any Quarterly Dividend Payment Date and the next subsequent
     Quarterly Divided Payment Date, a dividend of $1.00 per share as such
     amount may be adjusted pursuant to the last sentence of the preceding
     paragraph on the Series A Junior Participating Preferred Stock shall
     nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

          (C)  Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Junior Participating Preferred Stock from the Quarterly
     Dividend Payment Date next preceding the date of issue of such shares of
     Series A Junior Participating Preferred Stock, unless the date of issue of
     such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Series A Junior Participating
     Preferred Stock entitled to receive a quarterly dividend and before such
     Quarterly Dividend Payment Date, in either of which events such dividends
     shall begin to accrue and be cumulative from such Quarterly Dividend
     Payment Date.  Accrued but unpaid dividends shall not bear interest. 
     Dividends paid on the shares of Series A Junior Participating Preferred
     Stock  in an amount less than the total amount of such dividends at the
     time accrued and payable on such shares shall be allocated pro rata on a
     share-by-share basis among all such shares at the time outstanding.  The
     Board of Directors may fix a record date for the determination of holders
     of shares of Series A Junior Participating Preferred Stock  entitled to
     receive payment of a dividend or distribution declared thereon, which
     record date shall be no more than 60 days prior to the date fixed for the
     payment thereof.

          Section 3.  VOTING RIGHTS.  The holders of shares of Series A Junior
     Participating Preferred Stock  shall have the following voting rights:

          (A)  Subject to the provision for adjustment hereinafter set forth,
     each share of Series A Junior Participating Preferred Stock shall entitle
     the holder thereof to 100 votes on all matters submitted to a vote of the
     stockholders of the Corporation.  In the event the Corporation shall at any
     time after the Rights Declaration Date (i) declare any dividend on Common
     Stock payable in shares of Common Stock, (ii) subdivide the outstanding
     Common Stock, or (iii) combine the outstanding Common Stock into a smaller
     number of shares, then in each such case the number of votes per share to
     which holders of shares of Series A Junior Participating Preferred Stock 
     were entitled immediately prior to such event shall be adjusted by
     multiplying such number by a fraction the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.

          (B)  Except as otherwise provided herein or by law, the holders of
     shares of Series A Junior Participating Preferred Stock  and the holders of
     shares of Common Stock shall vote together as one class on all matters
     submitted to a vote of stockholders of the Corporation.

          (C)  (i)       If at any time dividends on any Series A Junior
          Participating Preferred

                                        3

<PAGE>

          Stock  shall be in arrears in an amount equal to six (6) quarterly
          dividends thereon, the occurrence of such contingency shall mark the
          beginning of a period (herein called a "default period") which shall
          extend until such time when all accrued and unpaid dividends for all
          previous quarterly dividend periods and for the current quarterly
          dividend period on all shares of Series A Junior Participating
          Preferred Stock then outstanding shall have been declared and paid or
          set apart for payment.  During each default period, all holders of
          Preferred Stock (including holders of the Series A Junior
          Participating Preferred Stock) with dividends in arrears in an amount
          equal to six (6) quarterly dividends thereon, voting as a class,
          irrespective of series, shall have the right to elect two (2)
          Directors.

               (ii)      During any default period, such voting right of the
          holders of Series A Junior Participating Preferred Stock may be
          exercised initially at a special meeting called pursuant to
          subparagraph (iii) of this Section 3(C) or at any annual meeting of
          stockholders, and thereafter at annual meetings of stockholders,
          provided that neither such voting right nor the right of the holders
          of any other series of Preferred Stock, if any, to increase, in
          certain cases, the authorized number of Directors shall be exercised
          unless the holders of ten percent (10%) in number of shares of
          Preferred Stock outstanding shall be present in person or by proxy. 
          The absence of a quorum of the holders of Common Stock shall not
          affect the exercise by the holders of Preferred Stock of such voting
          right.  At any meeting at which the holders of Preferred Stock shall
          exercise such voting right initially during an existing default
          period, they shall have the right, voting as a class, to elect
          Directors to fill such vacancies, if any, in the Board of Directors as
          may then exist up to two (2) Directors or, if such right is exercised
          at an annual meeting, to elect two (2) Directors.  If the number which
          may be so elected at any special meeting does not amount to the
          required number, the holders of the Preferred Stock shall have the
          right to make such increase in the number of Directors as shall be
          necessary to permit the election by them of the required number. 
          After the holders of the Preferred Stock shall have exercised their
          right to elect Directors in any default period and during the
          continuance of such period, the number of Directors shall not be
          increased or decreased except by vote of the holders of Preferred
          Stock as herein provided or pursuant to the rights of any equity
          securities ranking senior to or PARI PASSU with the Series A Junior
          Participating Preferred Stock.

               (iii)     Unless the holders of Preferred Stock shall, during an
          existing default period, have previously exercised their right to
          elect Directors, the Board of Directors may order, or any stockholder
          or stockholders owning in the aggregate not less than ten percent
          (10%) of the total number of shares of Preferred Stock outstanding,
          irrespective of series, may request, the calling of a special meeting
          of the holders of Preferred Stock, which meeting shall thereupon be
          called by the President, a Vice-President or the Secretary of the
          Corporation.  Notice of such meeting and of any annual meeting  at
          which holders of Preferred Stock are entitled to vote pursuant to this
          paragraph (C) (iii) shall be given to each holder of record of
          Preferred Stock by mailing a copy of such notice to him at his last
          address as the same appears on the books of the Corporation.  Such
          meeting shall be called for a time not earlier than 20

                                        4

<PAGE>

          days and not later than 60 days after such order or request or in
          default of the calling of such meeting within 60 days after such order
          or request, such meeting may be called on similar notice by any
          stockholder or stockholders owning in the aggregate not less than ten
          percent (10%) of the total number of shares of Preferred Stock
          outstanding.  Notwithstanding the provisions of this paragraph
          (C)(iii),  no such special meeting shall be called during the period
          within 60 days immediately preceding the date fixed for the next
          annual meeting of the stockholders. 

               (iv)      In any default period, the holders of Common Stock, and
          other classes of stock of the Corporation if applicable, shall
          continue to be entitled to elect the whole number of Directors until
          the holders of Preferred Stock shall have exercised their right to
          elect two (2) Directors voting as a class, after the exercise of which
          right (x) the Directors so elected by the holders of Preferred Stock
          shall continue in office until their successors shall have been
          elected by such holders or until the expiration of the default period,
          and (y) any vacancy in the Board of Directors may (except as provided
          in paragraph (C)(ii) of this Section 3) be filled by vote of a
          majority of the remaining Directors theretofore elected by the holders
          of the class of stock which elected the Director whose office shall
          have become vacant.  References in this paragraph (C) to Directors
          elected by the holders of a particular class of stock shall include
          Directors elected by such Directors to fill vacancies as provided in
          clause (y) of the foregoing sentence.

               (v)       Immediately upon the expiration of a default period,
          (x) the right of the holders of Preferred Stock as a class to elect
          Directors shall cease, (y) the term of any Directors elected by the
          holders of Preferred Stock as a class shall terminate, and (z) the
          number of Directors shall be such number as may be provided for in the
          Certificate of Incorporation or by-laws irrespective of any increase
          made pursuant to the provisions of paragraph (C)(ii) of this Section 3
          (such number being subject, however, to change thereafter in any
          manner provided by law or in the Certificate of Incorporation or by-
          laws).  Any vacancies in the Board of Directors effected by the
          provisions of clauses (y) and (z) in the preceding sentence may be
          filled by a majority of the remaining Directors.

          (D)   Except as set forth herein, holders of Series A Junior
     Participating Preferred Stock  shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

          Section 4.  CERTAIN RESTRICTIONS.

          (A)  Whenever quarterly dividends or other dividends or distributions
     payable on the Series A Junior Participating Preferred Stock  as provided
     in Section 2 are in arrears, thereafter and until all accrued and unpaid
     dividends and distributions, whether or not declared, on shares of Series A
     Junior Participating Preferred Stock  outstanding shall have been paid in
     full, the Corporation shall not

                                        5

<PAGE>
          
               (i)       declare or pay dividends on, make any other
          distributions on, or redeem or purchase or otherwise acquire for
          consideration any shares of stock ranking junior (either as to
          dividends or upon liquidation, dissolution or winding up) to the
          Series A Junior Participating Preferred Stock;

               (ii)      declare or pay dividends on or make any other
          distributions on any shares of stock ranking on a parity (either as to
          dividends or upon liquidation, dissolution or winding up) with the
          Series A Junior Participating Preferred Stock, except dividends paid
          ratably on the Series A Junior Participating Preferred Stock and all
          such parity stock on which dividends are payable or in arrears in
          proportion to the total amounts to which the holders of all such
          shares are then entitled;

               (iii)     redeem or purchase or otherwise acquire for
          consideration shares of any stock ranking on a parity (either as to
          dividends or upon liquidation, dissolution or winding up) with the
          Series A Junior Participating Preferred Stock, provided that the
          Corporation may at any time redeem, purchase or otherwise acquire
          shares of any such parity stock in exchange for shares of any stock of
          the Corporation ranking junior (either as to dividends or upon
          dissolution, liquidation or winding up) to the Series A Junior
          Participating Preferred Stock or;

               (iv)      purchase or otherwise acquire for consideration any
          shares of Series A Junior Participating Preferred Stock, or any shares
          of stock ranking on a parity with the Series A Junior Participating
          Preferred Stock, except in accordance with a purchase offer made in
          writing or by publication (as determined by the Board of Directors) to
          all holders of such shares upon such terms as the Board of Directors,
          after consideration of the respective annual dividend rates and other
          relative rights and preferences of the respective series and classes,
          shall determine in good faith will result in fair and equitable
          treatment among the respective series or classes.

          (B)  The Corporation shall not permit any subsidiary of the
     Corporation to purchase or otherwise acquire for consideration any shares
     of stock of the Corporation unless the Corporation could, under paragraph
     (A) of this Section 4, purchase or otherwise acquire such shares at such
     time and in such manner.

          Section 5.  REACQUIRED SHARES.  Any shares of Series A Junior
     Participating Preferred Stock purchased or otherwise acquired by the
     Corporation in any manner whatsoever shall be retired and cancelled
     promptly after the acquisition thereof.  All such shares shall upon their
     cancellation become authorized but unissued shares of Preferred Stock and
     may be reissued as part of a new series of Preferred Stock to be created by
     resolution or resolutions of the Board of Directors, subject to the
     conditions and restrictions on issuance set forth herein.

          Section 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.  

          (A)  Upon any liquidation (voluntary or otherwise), dissolution or
     winding up of the Corporation, no distribution shall be made to the holders
     of shares of stock ranking junior (either as to dividends or upon
     liquidation, dissolution or winding up) to the Series A Junior
     Participating Preferred Stock unless, prior thereto, the holders of shares
     of Series A Junior Participating Preferred Stock shall have received $100
     per share, plus an amount equal to accrued and unpaid dividends and
     distributions thereon, whether or not declared, to the date of such payment
     (the "Series A Liquidation Preference").  Following the payment of the full
     amount of the Series A Liquidation Preference, no additional distributions
     shall be made to the holders of shares of Series A Junior Participating
     Preferred Stock unless, prior thereto, the holders of shares of Common
     Stock shall have received an amount per share (the "Common Adjustment")
     equal to the quotient obtained by dividing (i) the Series A Liquidation
     Preference by (ii) 100 (as appropriately adjusted as set forth in
     subparagraph (C) below to reflect such events as stock splits, stock
     dividends and recapitalization with respect to the Common Stock) (such
     number in clause (ii), the "Adjustment Number").  Following the payment of
     the full amount of the Series A Liquidation Preference and the Common
     Adjustment in respect of all outstanding shares of Series A Junior
     Participating Preferred Stock  and Common Stock, respectively, holders of
     Series A Junior Participating Preferred Stock and holders of shares of
     Common Stock shall receive their ratable and proportionate share of the
     remaining assets to be distributed in the ratio of the Adjustment Number to
     1 with respect to such Preferred Stock and Common Stock, on a per share
     basis, respectively.

          (B)  In the event, however, that there are not sufficient assets
     available to permit payment in full of the Series A Liquidation Preference
     and the liquidation preferences of all other series of preferred stock, if
     any, which rank on a parity with the Series A Junior Participating
     Preferred Stock, then such remaining assets shall be distributed ratably to
     the holders of such parity shares in proportion to their respective
     liquidation preferences.  In the event, however, that there are not
     sufficient assets available to permit payment in full of the Common
     Adjustment, then such remaining assets shall be distributed ratably to the
     holders of Common Stock.

          (C)  In the event the Corporation shall at any time after the Rights
     Declaration Date (i) declare any dividend on Common Stock payable in shares
     of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
     combine the outstanding Common Stock into a smaller number of shares, then
     in each such case the Adjustment Number in effect immediately prior to such
     event shall be adjusted by multiplying such Adjustment Number by a fraction
     the numerator of which is the number of shares of Common Stock outstanding
     immediately after such event and the denominator of which is the number of
     shares of Common Stock that were outstanding immediately prior to such
     event.  

          Section 7.  CONSOLIDATION, MERGER, ETC.  In case the corporation shall
     enter into any consolidation, merger, combination or other transaction in
     which the shares of Common Stock are exchanged for or changed into other
     stock or securities, cash and/or any other property, then in any such case
     the shares of Series A Junior Participating Preferred Stock  shall at the
     same time be similarly exchanged or changed in an amount per share (subject
     to the provision

                                        7

<PAGE>

     for adjustment hereinafter set forth) equal to 100 times the aggregate
     amount of stock, securities, cash and/or any other property (payable in
     kind), as the case may be, into which or for which each share of Common
     Stock is changed or exchanged.  In the event the Corporation shall at any
     time after the Rights Declaration Date (i) declare any dividend on Common
     Stock payable in shares of Common Stock, (ii) subdivide the outstanding
     Common Stock, or (iii) combine the outstanding Common Stock into a smaller
     number of shares, then in each such case the amount set forth in the
     preceding sentence with respect to the exchange or change of shares of
     Series A Junior Participating Preferred Stock shall be adjusted by
     multiplying such amount by a fraction the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.

          Section 8.  NO REDEMPTION.   The shares of Series A Junior
     Participating Preferred Stock shall not be redeemable.

          Section 9.  RANKING.  The Series A Junior Participating Preferred
     Stock shall rank junior to all other series of the Corporation's Preferred
     Stock which may be issued from time to time as to the payment of dividends
     and the distribution of assets, unless the terms of any such series shall
     provide otherwise.

          Section 10.  AMENDMENT.  The Restated Certificate of Incorporation of
     the Corporation shall not be further amended in any manner which would
     materially alter or change the powers, preferences or special rights of the
     Series A Junior Participating Preferred Stock  so as to affect them
     adversely without the affirmative vote of the holders of a majority or more
     of the outstanding shares of Series A Junior Participating Preferred Stock,
     voting separately as a class.

          Section 11.  FRACTIONAL SHARES.  Series A Junior Participating
     Preferred Stock may be issued in fractions of a share which shall entitle
     the holder, in proportion to such holder's fractional shares, to exercise
     voting rights, receive dividends, participate in distributions and to have
     the benefit of all other rights of holders of Series A Junior Participating
     Preferred Stock.

business on March 11, 1996.

          IN WITNESS WHEREOF, said ECOLAB INC. has caused this Amended
Certificate to be signed by Kenneth A. Iverson, its Vice President and
Secretary, this 11th day of March, 1996.

any such share or shares on the part of any other person whether or not it shall
have express or other notice thereof.

SECTION 3.  LOST CERTIFICATES.  The Corporation may issue a new certificate of
stock in the place of any certificate theretofore issued by it, alleged to have

stolen, destroyed or mutilated certificate, or his legal representative, to give
the Corporation a bond, limited or unlimited, in such sum and in such form and
with such surety or sureties as the Board of Directors in its absolute
discretion shall determine is sufficient to indemnify the Corporation against
any claim that may be made against it on account of the alleged loss, theft,
destruction or mutilation of any such certificate, or the issuance of a new
certificate.  Anything herein to the contrary notwithstanding, the Board of
Directors in its absolute discretion may refuse to issue any such new

Directors may fix, in advance, a record date, which shall not be less than ten

than sixty (60) days prior to any other action.  A determination of stockholders
of record entitled to notice of and to vote at a meeting of stockholders shall
apply to any adjournment of the meeting unless the Board of Directors shall
elect to fix a record date for the adjourned meeting.

                         FIRST DECLARATION OF AMENDMENT


Pursuant to Section 1.3 of the Ecolab Mirror Savings Plan ("Plan") and Section
5.1 of the Ecolab Inc. Administrative Document for Non-Qualified Benefit Plans
which is incorporated into the Plan by reference ("Administrative Document"),
the Company amends the Plan as set forth below.

1.   Subsections (1) and (2) of Section 6.1 of the Plan are hereby amended to
read as follows:

          "(1) HYPOTHETICAL INVESTMENT FUND FOR MATCHING CONTRIBUTIONS.  The
     Company has designated the Ecolab Stock Fund under the Savings Plan as the
     Hypothetical Investment Fund for Matching Contributions.  Matching
     Contributions shall be deemed to have been invested in the Ecolab Stock
     Fund for purposes of crediting earnings and losses to the portion of the
     Executive's Account which is attributable to Matching Contributions.
     Earnings on any amounts deemed to have been invested in the Ecolab Stock
     Fund shall be deemed to have been reinvested in the Ecolab Stock Fund.

          (2)  HYPOTHETICAL INVESTMENT FUNDS FOR EXECUTIVE DEFERRALS.  The
     Hypothetical Investment Funds for purposes of the portion of an Executive's
     Account which is attributable to his Executive Deferrals shall be those
     same Investment Funds designated by the Company from time to time under the
     Savings Plan.  Each Executive (or his Death Beneficiary) shall be deemed to
     have elected one or more Hypothetical Investment Funds in which his
     Executive Deferrals are deemed to have been invested for purposes of
     crediting earnings and losses to the portion of the Executive's Account
     which is attributable to Executive Deferrals.  The Executive's or Death
     Beneficiary's deemed election of Hypothetical Investment Funds hereunder
     shall be based on the Executive's or Death Beneficiary's investment
     election (or default election) under the Savings Plan, as in effect from
     time to time.  The Company may deem an Executive's Executive Deferrals to
     have been invested in the Hypothetical Investment Fund deemed elected by
     the Executive, if any, or may instead, in its sole discretion, deem such
     Executive Deferrals to have been invested in one or more Hypothetical
     Investment Funds selected by the Company.  Earnings on any amounts deemed
     to have been invested in any Hypothetical Investment Fund shall be deemed
     to have been reinvested in such Hypothetical Investment Fund.
     Notwithstanding the foregoing, any Executive who is subject to Section
     16(b) of the Securities Exchange Act of 1934 shall not be deemed to have
     directed any Executive Deferrals to the Ecolab Stock Fund and may make a
     separate election to have such Executive Deferrals which would otherwise
     have been deemed to be invested in the Ecolab Stock Fund deemed invested in
     one or more of the other Hypothetical Investment Funds.  An Executive

<PAGE>

     shall be deemed, on the day prior to becoming subject to Section 16(b) or
     at such other time as he is subject to Section 16(b), to have elected to
     have Executive Deferrals then deemed to be invested in the Ecolab Stock
     Fund invested in the Hypothetical Investment Fund known as the Fidelity
     Retirement Money Market Portfolio unless another permitted election is in
     place."

2.   This amendment to the Plan shall be effective as of January 1, 1995.

IN WITNESS WHEREOF, the Company has caused this instrument to be executed by its
authorized officers and its corporate seal affixed, this 27th day of September,
1995.

3.      Annuity Values Weighted:        75% male, 25% female.

4.      Early Commencement:             The Mirror Pension Benefit shall be
                                        reduced by one two hundred eightieth
                                        (1/280th) for each month that the date
                                        of the commencement of payment precedes
                                        the date on which the Executive will
                                        attain age sixty-two (62).  If the
                                        Executive's Ecolab Pension Plan benefit
                                        is affected by Section 415 of the Code,
                                        the Administrator shall make such
                                        further adjustments to the Mirror
                                        Pension Benefit as the Administrator, in
                                        his or her sole discretion, deems
                                        appropriate to ensure that the total
                                        early retirement benefit from the Ecolab
                                        Pension Plan and the Ecolab Mirror
                                        Pension Plan equals the early retirement
                                        benefit the Executive would have been
                                        entitled to under the Ecolab Pension
                                        Plan without regard to the Code

                                        If payment is in the form of a single
                                        lump sum, the lump sum amount shall be
                                        based on the lump sum interest rate
                                        defined in item 1 above, the mortality
                                        assumptions specified in items 2 and 3

                              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.

1995 OVERVIEW
- ------------------------------------------------------------------------------

During 1995, Ecolab achieved record financial results and made important
progress toward its strategic development. All of the company's established
businesses achieved record sales and income results, and Ecolab's stock price
rose over 40 percent during the year to a record level. This strong performance
was achieved despite higher raw material costs and a competitive environment
that limited selling price increases. The company's significant accomplishments
included: 

- - Consolidated net sales reached a record $1.3 billion and increased 11 percent
over the prior year. 

- - Net income reached a record $99 million, or $1.50 per share. Net income per
share increased 12 percent over pro forma net income per share of $1.34 in 1994.

- - The company continued to realize strong operating cash flows and maintain very
low debt levels. Total debt to capitalization was 26 percent at year-end 1995,
up modestly from its lowest level in 10 years of 24 percent at year-end 1994. As
a result, Ecolab's debt continued to be rated "A-" by Standard & Poor's, and the
company maintained its long-term financial objective of an investment grade
balance sheet.

- - The return on beginning shareholders' equity for 1995 was 21 percent. This is
the fourth consecutive year that the company has 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 fourth consecutive 
year. The annual dividend rate was increased by 12 percent to $0.56 per 
common share. The company has paid dividends on its common stock for 59 
consecutive years.

- - During 1995, the company broadened its Water Care Services operations by 
making two additional acquisitions. The company will continue to pursue water 
care acquisitions and focus on the development of its Water Care Services 
strategies. Also, during 1995, the company reestablished operations in South 
Africa through two acquisitions.

   Consolidated net sales were $1.3 billion in 1995, an 11 percent increase 
over net sales of $1.2 billion in 1994. Both the company's United States and 
International operations contributed to this increase. The growth in net 
sales reflected the benefits of new product introductions, an increased 
sales-and-service force, competitive gains and generally good economic 
conditions in the hospitality and lodging industries.


[GRAPH]

   Consolidated operating income reached $163 million in 
1995 compared to operating income of $137 million in 1994. Consolidated
operating income for 1994 was negatively affected by $8 million of one-time
merger costs and expenses related to the company's December 1994 merger with Kay
Chemical Company and affiliates ("Kay") of Greensboro, North Carolina.
Consolidated operating income increased 12 percent over pro forma operating
income for 1994, which excludes the negative effects of the merger costs and
expenses. With the exception of the start-up Water Care Services and South
African operations,

                          FINANCIAL 
                              DISCUSSION

all of the company's United States businesses and all regions of 
International operations contributed to the improvement in consolidated 
operating income. The operating income margin was 12.1 percent in 1995, 
compared to the pro forma operating income margin of 12.0 percent in 1994. 
The modest increase in the operating income margin reflected an improvement 
in selling, general and administrative expenses as a percent of net sales, 
partially offset by a decrease in the gross profit margin. The gross profit 
margin was 55.0 percent in 1995 compared to a gross profit margin of 55.9 
percent in 1994. The decrease in the gross profit margin reflected increased 
raw material costs and limited selling price increases due to competitive 
pressures in several of the markets in which the company does business. Raw 
material cost increases moderated somewhat during the second half of 1995. 
Management continues to focus on future raw material cost increases and 
competition in the marketplace to minimize any impact on the company's 
overall operating results. Selling, general and administrative expenses 
represented 42.9 percent of net sales in 1995 compared to 43.8 percent of net 
sales in 1994. These expenses decreased as a percentage of net sales, 
primarily due to the company's continued cost-control efforts. 

   Net income for 1995 totaled $99 million, or $1.50 per share, compared to
reported net income of $85 million, or $1.25 per share for 1994. The table on
page 24 also presents pro forma net income for 1994 and 1993 on a basis 
consistent with the way it has been reported subsequent to the company's 
December 1994 merger with Kay. The pro forma adjustments include:

- - The after-tax effect of merger costs and expenses related to the Kay 
transaction.

- - Income tax expense incurred to record a deferred tax liability to reflect 
Kay's future net taxable temporary differences upon its merger with Ecolab.

- - Income tax expense adjustments related to the loss of Kay's Subchapter S 
income tax status. Prior to the merger, Kay was a Subchapter S corporation 
for federal income tax purposes and therefore did not pay U.S. income taxes. 
Effective with the merger, Kay has been included in the company's U.S. 
federal income tax return and, therefore, income tax expense in 1995 no 
longer reflects the Subchapter S related tax benefit.

   Net income for 1995 increased 10 percent over 1994 pro forma net income of 
$90 million. The improvement in net income reflected a strong operating 
income performance and a reduction in net interest expense which was 
partially offset by lower equity in earnings of the Henkel-Ecolab joint 
venture. On a per share basis, 1995 net income per share of $1.50 increased 
12 percent over pro forma net income per share of $1.34 in 1994. This 
comparison of net income per share benefited from a smaller number of average 
shares outstanding in 1995 due to the purchase of approximately 3.5 million 
shares of the company's common stock in mid-1995 under the terms of a "Dutch 
auction" self-tender offer.

Consolidated net sales were $1.2 billion in 1994 and increased 10 percent over
net sales of $1.1 billion in 1993. Both the company's United States and
International operations contributed to this increase. New product introductions
and a larger sales-and-service force made significant contributions to the sales
improvement. 

   Consolidated operating income increased 6 percent to $137 million in 1994 
from $129 million in 1993. This increase reflected improved performance by 
both the company's United States and International operations, with solid 
growth in the U.S. Institutional business and double-digit growth in the U.S. 
Pest Elimination and Janitorial businesses and in International's Asia 
Pacific operations. Operating income for both years was affected by one-time 
transactions. Operating income for 1994 included $8 million of one-time 
merger costs and expenses related to the Kay transaction. In 1993, operating 
income was negatively affected by a net charge from restructuring 
manufacturing operations, environmental costs related to former manufacturing 
operations, and the sale of a U.S. and an International business. These 
transactions reduced operating income for 1993 by approximately $8 million. 
Excluding these transactions, operating income margins were 12.0 percent in 
1994 compared with 12.4 percent in 1993.

   On a pro forma basis, net income for 1994 was $90 million, or $1.34 per 
share, and increased 12 percent over pro forma net income of $81 million, or 
$1.20 per share, in 1993. In addition to an improvement in operating income, 
net income benefited from a significant reduction in net interest expense and 
increased equity in earnings of the Henkel-Ecolab joint venture in 1994. 
These benefits were partially offset by an increase in the overall effective 
income tax rate. The comparison of net income also benefited from the effect 
of one-time transactions that reduced net income in 1993 by approximately $2 
million.

   United States sales for 1995 were slightly more than $1.0 billion, an 
increase of 9 percent over net sales of $942 million in 1994. All divisions 
contributed to this sales improvement. United States sales benefited from new 
products, increased product volumes, favorable product mix, new customer 
business, retention of key customers, a larger sales-and-service force and 
continued good market conditions in the hospitality and lodging industries. 
However, selling price increases were limited during 1995 due to competitive 
pressures in several of the markets in which the company does business. Sales 
of the U.S. Institutional Division increased 6 percent over 1994. 
Institutional sales growth included increased sales in all major product 
lines, with particularly strong growth in its Ecotemp program and the 
specialty products group. The Pest Elimination Division reported 12 percent 
sales growth for 1995 and continued to successfully leverage its alliances 
with the Institutional and Food and Beverage Divisions. Sales growth for 
Kay's United States operations was 13 percent for 1995 due to new customers 
and the growth of the large quickservice chains, which are the core of Kay's 
business. The Textile Care Division reported a sales increase of 7 percent 
for 1995, which included double-digit growth in


[GRAPH]

commercial laundry and hospitality market sales. Sales of the Janitorial 
Division increased 5 percent over the prior year. Janitorial sales growth was 
due to increased sales of its Airkem products, with sales of its Signature 
Label program flat versus the strong sales reported in 1994. The Food and 
Beverage Division (formerly the Klenzade Division) reported sales growth of 
12 percent, including double-digit growth in sales to the beverage, brewery, 
dairy plant and food processing markets. The company's recently acquired 
Water Care Services operations contributed $11 million to United States sales 
during 1995.

   Operating income for the company's United States operations totaled $147 
million in 1995, an increase of 10 percent over operating income of $135 
million in 1994. Operating income margins were 14.3 percent for 1995 and were 
unchanged from the prior year. Operating income growth included continued 
good growth of the U.S. Institutional Division and double-digit growth of all 
of the other United States businesses, with the exception of the start-up 
Water Care Services operations. Operating income for 1995 reflected strong 
sales and the benefits of companywide cost-control programs. Operating income 
was negatively affected by higher raw material costs and competitive pricing 
pressures. The United States business continued to invest in its 
sales-and-service force, though at a slower pace compared to the last two 
years. In 1995, excluding the Water Care Services acquisitions, the company 
added approximately 100 new United States sales-and-service personnel 
compared to additions of approximately 200 in 1994 and 300 in 1993. 

1994 COMPARED WITH 1993

United States sales totaled $942 million in 1994 and increased 9 percent over 
net sales of $867 million in 1993. All divisions contributed to this 
increase. Sales of the U.S. Institutional Division for 1994 increased 8 
percent over the prior year. During 1994, Institutional had strong sales in 
all product lines with excellent growth in warewashing, which is its most 
significant product line, and exceptional growth in its Ecotemp program and 
the specialty products group. Pest Elimination Division sales for 1994 
increased 15 percent over 1993. Pest Elimination's sales growth reflected new 
customer business added by leveraging off the Institutional and Food and 
Beverage Divisions' customer bases and to new product and service offerings. 
Sales of the Textile Care Division increased 12 percent over 1993 due to 
additional sales related to an acquisition in December 1993 and to strong 
sales in the healthcare and shirt laundry markets. The Janitorial Division 
reported sales growth of 22 percent for 1994. Janitorial's sales growth 
included exceptional growth of its Signature Label program. Food and Beverage 
Division sales for 1994 increased 5 percent over the prior year due to new 
product introductions and successful growth in the food processing and dairy 
plant markets. Kay's United States operations reported sales growth of 6 
percent for 1994, primarily due to the growth of the large quickservice 
chains that Kay serves.

   Operating income for the company's United States operations totaled $135 
million and increased 8 percent over operating income of $124 million in 
1993. Operating income margins were 14.3 percent for both 1994 and 1993. The 
increase in operating income was primarily due to continued growth of the 
Institutional business and double-digit gains from the Pest Elimination and 
Janitorial Divisions. United States operating income performance reflected 
strong sales, improved product mix and the effects of continued cost 
controls, which were partially offset by the effect of continued investments 
in the sales-and-service force. Operating income improvements in 1994 
included a modest benefit from favorable raw material costs. Operating income 
comparisons also benefited due to charges that were included in 1993 for 
unusual transactions. Operating income in 1993 included a net charge for 
manufacturing restructuring and environmental compliance costs which were 
partially offset by a gain on the sale of the Textile Care Division's fashion 
processing business.

   The company's International business consists of Canadian, Asia Pacific, 
Latin American and African operations and the international operations of 
Kay. Net sales of the company's International operations totaled $311 million 
in 1995, a 17 percent increase over sales of $266 million in 1994. The 
effects of currency translation did not have a significant impact on overall 
International sales growth. Asia Pacific, International's largest operation, 
reported sales growth of 14 percent for 1995 with good performances in its 
Institutional and Food and Beverage markets. Asia Pacific sales results 
included double-digit growth in the East Asia region and New Zealand, modest 
growth in Japan and flat results in Australia. Sales in China decreased due 
to difficult local economic and business conditions. Sales in the Latin 
American region increased 22 percent for 1995 with good growth in all 
markets. This increase included the continuing improvement of performance in 
Brazil due to a more stable economic environment and the benefit of 
management changes the company made in the region during 1993 and 1994. Sales 
in Mexico grew at double-digit rates in local currencies; however, this 
improvement was more than offset by the negative effects of the devaluation 
of the Mexican peso in early 1995. The company's Canadian operations reported 
sales growth of 5 percent for 1995. Canada's sales growth included 
double-digit gains in sales to the Food and Beverage and Janitorial markets 
and a modest increase in sales to the Institutional and Textile Care markets. 
International sales in 1995 also included approximately


[GRAPH]

$6 million of sales from South African operations. The company acquired two 
businesses in South Africa during 1995, representing annualized sales of 
approximately $20 million. Sales of Kay's International operations increased 
18 percent for 1995 as it continued to expand service to locations where its 
large corporate customers do business.

   Operating income for International operations totaled $20 million in 1995, 
a 32 percent increase over 1994's operating income of $15 million. Operating 
income margins improved to 6.3 percent in 1995 from 5.6 percent the prior 
year. Operating income improved very significantly in Latin America and Kay, 
and grew at nearly double-digit rates in Asia Pacific and Canada. 
International's operating income for 1995 included favorable benefits from 
currency translation in the Asia Pacific region; however, it was negatively 
affected by a $1 million pre-tax charge in the first quarter related to the 
devaluation of the Mexican peso. Operating income in 1994 also included an 
unusual charge of $1 million which was incurred in the second quarter of 1994 
due to the government's economic program and monetary plan in Brazil. 

   Operating income margins of the company's International operations are 
substantially less than the operating income margins realized for the 
company's United States 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.

1994 COMPARED WITH 1993

International revenues for 1994 of $266 million increased 13 percent over 
revenues of $235 million in 1993. The effects of currency translation did not 
have a significant impact on overall International sales growth. Asia Pacific 
reported sales growth of 13 percent for 1994, which included double-digit 
sales gains in the East Asia region and excellent sales growth in Japan, New 
Zealand and China. Sales growth in the Latin American region increased 6 
percent over 1993. Results for the Latin American region reflected 
significantly improved results in Brazil, good growth in Mexico and 
double-digit growth in Argentina. These improvements reflected the benefits 
of management changes that the company made in the region in late 1993 and 
early 1994 and an improved economic environment in Brazil. Sales of the 
company's Canadian operations increased 22 percent during 1994 due to 
additional sales related to a December 1993 acquisition, new product 
introductions and improved economic conditions in Canada. Sales of Kay's 
International operations increased 42 percent during 1994. Kay's operations 
are relatively new within international markets and growth is principally due 
to expanding service to all of the various international locations in which 
its existing customers operate.

   International operating income totaled $15 million in 1994, compared with 
operating income of $9 million in 1993. Operating income margins were 5.6 
percent compared with operating income margins of 4.0 percent in 1993. 
Operating income comparisons were favorably affected by the first quarter 
1993 sale of the company's G.H. Wood janitorial distribution business in 
Canada. Excluding the loss on the sale of these operations from 1993's 
operating income, International's operating income for 1994 increased by 14 
percent over 1993. This improvement in operating income was due to 
double-digit growth in Asia Pacific and Kay's international operations and to 
modest growth in Canada, which was partially offset by decreased operating 
income in the Latin American region. Latin America's operations included 
investments in management and the sale-and-service force and a $1 million 
one-time charge due to the government's new economic program and monetary 
plan 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 roy-


[GRAPH]

alty income and after deduction of intangible amortization, was $8 million in 
1995, a substantial decrease from the company's equity in earnings of $11 
million in 1994. These disappointing results reflected higher raw material 
costs, the cost of administrative changes being made by new management at the 
joint venture, higher overall income tax rates and weak conditions in the 
hospitality industry in the joint venture's key market of Germany. 
Administrative changes being made at the joint venture include investments in 
personnel, organizational development and financial and operating systems. 
The company does not expect that financial results will fully benefit from 
these investments until late 1996 and later years. The joint venture's 
revenues, although not consolidated in Ecolab's financial statements, 
increased 3 percent during 1995 when measured in Deutsche marks. However, due 
to the weaker U.S. dollar, joint venture revenues when translated into U.S. 
dollars totaled $909 million during 1995, an increase of 17 percent over 
revenues of $777 million in 1994. 

1994 COMPARED WITH 1993

The company's equity in earnings of the Henkel-Ecolab joint venture was $11
million in 1994, a substantial increase compared with equity in earnings of $8
million in 1993. Operating results for 1994's fourth quarter and fiscal year
included a $1 million benefit from a rebate under a manufacturing supply
agreement. The improvement in operating results also reflected product mix

improvements and cost-containment efforts of the joint venture. Joint venture 
revenues for 1994 of $777 million increased 2 percent over joint venture 
revenues of $758 million in 1993. 

CORPORATE

Corporate operating expense was $4 million in 1995, compared with $12 million 
in 1994 and $4 million in 1993. Corporate operating expense includes overhead 
costs directly related to the joint venture. In addition, expense in 1994 
also included $8 million of merger costs and expenses that were incurred as a 
result of the merger with Kay.

INTEREST AND INCOME TAXES

Net interest expense for 1995 was $12 million, an 11 percent decrease from net
interest expense of $13 million in 1994. The decrease in net interest expense
was due to increased interest income earned on higher average levels of cash and
cash equivalents held during 1995 and to the effect of lower interest rates on
the company's short-term borrowings.

   Net interest expense of $13 million for 1994 was a significant decrease 
from net interest expense of $21 million in 1993. This reduction in net 
interest expense made a significant contribution to the company's income 
improvement for 1994. The reduction was due to the early retirement of $75 
million of the company's 10.375 percent debentures in July 1993 and reduced 
borrowings under the Multicurrency Credit Agreement during 1994. 

   The annual effective income tax rate was 39.5 percent in 1995, compared 
with 40.7 percent in 1994. The decrease in the effective income tax rate in 
1995 was principally due to the effects of the Kay merger. The effective 
income tax rate was higher in 1994 due to the nondeductibility of a major 
portion of the one-time merger costs and expenses and to income tax expense 
incurred to record a net deferred tax liability to reflect Kay's future net 
taxable temporary differences upon its merger with Ecolab. The decrease in 
the 1995 effective income tax rate also reflected a lower overall effective 
rate on earnings of International operations. These benefits were partially 
offset by the loss of Kay's Subchapter S income tax status for 1995 and the 
elimination of income tax benefits from the discontinuation of most of the 
company's manufacturing operations in Puerto Rico.

   The effective income tax rate for all periods prior to 1995 reflects Kay's 
favorable income tax status as a Subchapter S corporation for income tax 
purposes prior to the December 1994 merger with Ecolab. Effective with the 
merger, Kay has been included in Ecolab's U.S. federal income tax return and, 
therefore, income tax expense no longer reflects the Subchapter S related tax 
benefit. The pro forma effects of this change in income tax status are 
included in the discussion of consolidated operating results above, and in 
Note 5 of the notes to consolidated financial statements. 

   The annual effective income tax rate of 40.7 percent in 1994 increased 
from 30.9 percent in 1993. In addition to the increase in the effective 
income tax rate in 1994 due to Kay's merger costs and expenses and the tax 
expense incurred to record Kay's net deferred tax liability, this increase 
reflected a higher overall effective rate on earnings of International 
operations, reduced income tax benefits from the company's operations in 
Puerto Rico and the effects of higher pre-tax income. Income taxes in 1993 
also included a one-time tax benefit associated with the sales of the 
company's G.H. Wood operation and the Textile Care fashion processing 
business. 

   As a result of tax losses on the disposition of a discontinued business in 
1992, U.S. federal income tax payments have been reduced by approximately $58 
million, including $3 million in 1995, $15 million in 1994 and $25 million in 
1993. 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. 

FINANCIAL POSITION, CASH FLOWS 
AND LIQUIDITY
- -------------------------------------------------------------------------------

FINANCIAL POSITION

The company maintained its long-term financial objective of an investment 
grade balance sheet throughout 1995. The company's debt rating was raised to 
an "A-" by Standard & Poor's in 1993, and this rating was maintained 
throughout 1994 and 1995. Significant changes to the company's balance sheet 
included the following:

- - During 1995, Ecolab purchased approximately 3.5 million shares (approximately 
5 percent of total outstanding shares) of the company's common stock, at a
purchase price of $25.00 per share, through a "Dutch auction" self-tender offer.
Shareholders' equity was reduced by the total cost to purchase these shares,
which was approximately $90 million. The cost was funded by excess cash and cash
equivalents and by approximately $30 million of short-term borrowings. In
addition, the company may

purchase approximately 2.5 million additional shares from time to time 
through open market and privately negotiated transactions to complete a 6 
million share repurchase program. 

- - Total debt increased $14 million during 1995 following decreases of $4 million
during 1994 and $85 million during 1993. The increase in 1995 was due to the
cash requirements of the stock purchase self-tender offer and business
acquisitions. 


[GRAPH]

The ratio of total debt to capitalization rose to 26 percent from 24 percent 
at year-end 1994, and compared to a ratio of 28 percent at year-end 1993. In 
addition to increased debt levels, the increase in the total debt to 
capitalization ratio during 1995 reflected the decrease in shareholders' 
equity which resulted from the purchase of common stock.

- - Working capital levels decreased to $48 million at year-end 1995 from $148
million at year-end 1994 and $110 million at year-end 1993. The decrease in
working capital levels during 1995 was principally due to the effects of the
purchase of common stock. The working capital increase during 1994 included 
a significant increase in cash and cash equivalents, and increased 
inventory levels to more efficiently meet local sales requirements.

- - Changes in the company's investment in the Henkel-Ecolab joint venture are
principally due to currency rate changes. 

CASH FLOWS

Cash provided by continuing operating activities totaled $163 million in 1995,
$154 million in 1994 and $151 million in 1993. These strong operating cash flows
were due in large part to strong earnings. Cash provided by continuing operating
activities for 1994 also included a one-time benefit from the receipt of an $18
million income tax refund related to prior years.

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

   Cash flows used for capital expenditures were $110 million in 1995, 
$88 million in 1994 and $68 million in 1993. Worldwide additions of 
merchandising equipment, primarily cleaning and sanitizing product 
dispensers, accounted for approximately 70 percent of each year's capital 
expenditures. Capital expenditures for 1995 also included costs related to a 
new manufacturing facility being constructed in Hebron, Ohio, in order to 
more efficiently meet sales requirements.

   Total debt was $161 million at December 31, 1995, compared with total debt 
levels of $147 million at year-end 1994 and $151 million at year-end 1993. 
Long-term debt repayments during 1995 included a scheduled payment of $14 
million related to the company's 9.68 percent senior notes. Additional 
borrowings were made during 1995 under the company's various short-term 
credit arrangements, principally to fund acquisitions and a portion of the 
cost of shares acquired under the self-tender offer. In January 1996, the 
company issued $75 million of 7.19 percent senior notes to a group of 
insurance companies. Proceeds from the debt were used to reduce short-term 
borrowings and for general corporate purposes.

   In 1995, the company increased its annual dividend rate for the fourth 
consecutive year. The company has paid dividends on its common stock for 59 
consecutive years. Cash dividends declared per share of common stock, by 
quarter, for each of the last three years were as follows:

LIQUIDITY

The company maintains a $150 million committed line of credit for general 
corporate financing needs. The credit facility includes a competitive bid 
feature to minimize the cost of the company's short-term borrowings. The 
company also has an established commercial paper program, supported by the 
committed line of credit, 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 1996 requirements for growth, possible 
acquisitions, new program investments, scheduled debt repayments and dividend 
payments.

<PAGE>
                              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.

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 38 percent, 38 percent
and 39 percent of consolidated inventories at year-end 1995, 1994
and 1993, 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. The company periodically
assesses the recoverability of intangible assets based on
anticipated future earnings and operating cash flows. 

INCOME PER COMMON SHARE 
Income per common share amounts are computed by dividing income
by the weighted average number of common shares outstanding.
Stock options did not have a significant dilutive effect. 

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.

</TABLE>

     The 9.68 percent senior notes were issued by the company to a
group of insurance companies. The notes include covenants
regarding consolidated shareholders' equity and amounts of
certain long-term debt.

     The company has a $150 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 U.S. dollars, Deutsche marks, or certain other
currencies, if available. The company has the option of various
interest rates based on short-term borrowing rates. Amounts
included in long-term debt at December 31, 1993, were denominated
in U.S. dollars and had an annual rate of interest of 3.4
percent. The agreement terminates in September 1998 and includes
covenants regarding interest coverage and the ratio of total debt
to capitalization. 

     In July 1993, the company redeemed $75 million of 10.375 percent
debentures originally scheduled for maturity in 1998 - 2017. An
extraordinary loss of $4.0 million (net of $2.5 million income
tax benefit), or $0.06 per share, which consisted primarily of
redemption premiums paid to debenture holders and the write-off
of deferred financing costs associated with the debt, was
recognized in the second quarter of 1993.

     As of December 31, the weighted average interest rate on notes
payable was 6.3 percent for 1995, 5.3 percent for 1994 and 4.6
percent for 1993. 

     As of December 31, 1995, the aggregate annual maturities of
long-term debt for the next five years were: 1996 - $16,697,000;
1997 - $15,553,000; 1998 - $15,346,000; 1999 - $15,264,000; and
2000 - $15,214,000.

     Interest expense was $15,857,000 in 1995, $16,213,000 in 1994 and
$25,977,000 in 1993. Total interest paid was $16,170,000 in 1995,
$16,402,000 in 1994 and $29,691,000 in 1993.

     In January 1996, the company issued $75 million of 7.19 percent
senior notes to a group of insurance companies. The notes mature
in January 2006. Proceeds from the debt were used to 
reduce short-term borrowings and for general corporate purposes.

     Other noncurrent liabilities included income taxes payable of $96
million at December 31, 1995, $94 million at December 31, 1994
and $61 million at December 31, 1993. 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 for trading purposes.

     The company enters into foreign currency forward exchange 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.

     The company had foreign currency forward exchange contracts with
a face amount denominated primarily in Deutsche marks and
totaling approximately $125 million at December 31, 1995, $110
million at December 31, 1994, and $115 million at December 31,
1993. The unrealized gains on these contracts were not
significant.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS
The carrying amount and the estimated fair value of other 
financial instruments held by the company as of year-end 1995 
and 1994 were:

Carrying amount
     Cash and cash equivalents                       $24,718         $98,255
     Long-term investments in securities               5,000           5,000
     Short-term debt                                  71,647          41,820

</TABLE>

     Cash equivalents are highly liquid investments with a maturity of
three months or less when purchased. The carrying amounts 
of cash equivalents and short-term debt approximate fair value
because of their short maturity.

     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. KAY MERGER
- --------------------------------------------------------------------------------
On December 7, 1994, the company issued approximately 4.5 million
shares of its common stock in exchange for all of the outstanding
common stock of Kay Chemical Company and affiliates ("Kay"). The
merger was accounted for as a pooling of interests and,
accordingly, the company's consolidated financial statements were
restated to include the accounts and operations of Kay for all
periods prior to the merger.

     In connection with the merger, $8.0 million of merger costs and
expenses ($6.9 million after-tax, or $0.10 per share) were
incurred and charged to expense in the fourth quarter of 1994.
The merger costs and expenses consisted of merger related bonus
payments made to Kay non-shareholder employees and legal,
accounting and investment banking fees. 

     Kay was a Subchapter S Corporation for income tax purposes and,
therefore, did not pay U.S. federal income taxes. Kay has been
included in Ecolab's U.S. federal income tax return effective
December 7, 1994, and, therefore, a net deferred tax liability
and corresponding charge to income tax expense of $1.3 million or
$0.02 per share was recorded upon closing to reflect Kay's net
taxable temporary differences.

     The table below includes unaudited pro forma net income and net
income per share amounts for 1994 and 1993, which reflect the
elimination of the nonrecurring merger costs and expenses in 1994
and pro forma adjustments to present income taxes on the basis on
which they are being reported subsequent to the merger.

7. INCOME TAXES
- --------------------------------------------------------------------------------
Effective January 1, 1993, the company adopted Statement of
Financial Accounting Standards No. 109, "Accounting for Income
Taxes" (FAS 109). This statement requires a change from the
deferred method to the asset and liability method of accounting
for income taxes. Under the asset and liability method, deferred
tax assets and liabilities are recognized for the expected future
tax consequences of temporary differences between financial
reporting amounts and the tax bases of existing assets and
liabilities. Deferred tax assets and liabilities are recorded
based on enacted tax laws and tax rates. Changes in enacted tax
rates are reflected in the income tax provision as they occur.

     The cumulative effect of this change in accounting principle
increased net income for 1993 by $4.7 million, or $0.07 per
share, including the impact of adoption of FAS 109 by the
Henkel-Ecolab joint venture. Prior years' financial statements
were not restated.

     Income before income taxes and equity in earnings of joint
venture consisted of:

     During 1993, the valuation allowance for deferred tax assets was
reduced by $3.3 million. This change in the valuation allowance
related to Canadian loss carryforwards, which became realizable
at that time as a result of the sale of the G.H. Wood janitorial
distribution business.

     Cash paid for income taxes was $55,214,000 in 1995, $34,686,000
in 1994 and $18,118,000 in 1993. As a result of tax losses on the
disposition of a discontinued business in 1992, the company's
U.S. federal income tax payments have been reduced by
approximately $58 million, including $3 million in 1995, $15
million in 1994 and $25 million in 1993. 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, 1995, undistributed earnings of international
subsidiaries and the joint venture of $57 million 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:

</TABLE>

     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.

     Effective July 1, 1993, the company adopted certain amendments to
its U.S. pension plan to improve the benefit formula and enhance
the value of pension benefits. Concurrent with these amendments,
the company lowered the discount rate used for determining the
pension benefit obligations and future service and interest cost
for the plan from 8.25 percent to 8.0 percent. These changes
resulted in an increase of $2.9 million in pension expense for
1993 and an increase of approximately $29 million in the
projected benefit obligation. The discount rate was lowered
further at year-end 1993 to 7.5 percent. This reduction in
discount rate resulted in an increase in the projected benefit
obligation as of December 31, 1993 of approximately $14 million
and an increase of $2.1 million in pension expense for 1994.

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

</TABLE>

     The discount rate was increased from 7.5 percent at year-end 1993
to 8.25 percent at year-end 1994. This increase in discount rate
resulted in a decrease in the projected benefit obligation as of
December 31, 1994 of approximately $22 million and a decrease of
$3.4 million in pension expense for 1995.

     The discount rate used for determining the year-end pension
benefit obligations and future service and interest cost was
decreased from 8.25 percent at year-end 1994 to 7.50 percent 
at year-end 1995. The effect of this change was to increase the
projected benefit obligation as of December 31, 1995 by
approximately $23 million.

     The adjustments required to recognize a minimum liability as of
year-end 1994 and 1993 have been included in the company's
noncurrent liability for postretirement health care and pension
benefits with an equal amount included in the Consolidated
Balance Sheet as an intangible asset. These adjustments resulted
principally from the plan amendments adopted in July 1993 and
discount rate changes.

     The company also has noncontributory 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, 1995 and the
annual expense for these plans was approximately $2 million in
each of the years 1995, 1994 and 1993.

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.

     Effective July 1, 1993, the company adopted certain amendments to
its U.S. plan. These amendments modified the company's subsidy
provided for each year of service and limit health care costs
which are eligible for subsidy by the company to a 4 percent
annual increase beginning in 1996. Also, effective July 1, 1993,
the company lowered the discount rate used for determining the
accumulated benefit obligation and future service and interest
cost for the plan to 8.0 percent from 8.25 percent at year-end
1992. These changes reduced postretirement health care expense
for 1993 by approximately $1.3 million and decreased the
accumulated benefit obligation by approximately $9 million. 

     The funded status of the postretirement health care plan was:

</TABLE>

     As of December 31, the discount rate for the postretirement
health care benefits plan was 7.50 percent for 1995, 8.25 percent
for 1994 and 7.50 percent for 1993. The changes in the discount
rate did not have a significant effect on the expense or
obligation of the plan.

     For measurement purposes, 11.5 percent (for pre-age 65 retirees)
and 9.0 percent (for post-age 65 retirees) annual rates 
of increase in the per capita cost of covered health care were
assumed for 1996. 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 health care
cost trend rate assumption has a significant effect on the
amounts reported. To illustrate, increasing the assumed health
care cost trend rate by 1 percentage point in each year would
increase the accumulated postretirement benefit obligation as of
year-end 1995 by approximately $4 million and 1995 expense by 
approximately $0.5 million.

     The after-tax expected long-term rate of return on plan assets
was 6.0 percent in 1995, 1994 and 1993. Plan assets consist
primarily of short-term investments.

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 contribution is invested in Ecolab common stock and
amounted to $5,919,000 in 1995, $5,156,000 in 1994 and $4,376,000
in 1993.

1994 and 3,008,706 for 1993.

     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
become exercisable over periods of up to six years from date of
grant and expire within 10 years and three months from date of
grant. Stock option transactions were:

     Stock awards are subject to restrictions including forfeiture in
the event of termination of employment. Restrictions generally
lapse over periods 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.

     In October 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 123, a new
standard of accounting and reporting for stock-based compensation
plans. The company is not required to adopt the new standard
until 1996. The company will continue 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 will have no effect on the company's
operating results. The company's financial statement disclosures
will be expanded in 1996, as required, to include pro forma
disclosures as if the fair value-based method of accounting had
been followed.

10. SHAREHOLDERS' EQUITY
- --------------------------------------------------------------------------------
The company's common stock was split two-for-one in the form of a
100 percent stock dividend paid January 18, 1994, to shareholders
of record on December 28, 1993. 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 100
million shares in 1995, 1994 and 1993. Treasury stock is stated
at cost. Dividends declared per share of common stock were $0.515
for 1995, $0.455 for 1994 and $0.395 for 1993.


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

     The company renewed its shareholder rights plan in February 1996.
One preferred stock purchase right will be issued for each
outstanding share of the company's common stock when the existing
rights expire on March 11, 1996. 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 at the time of the renewal of the rights plan, 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.

     The company maintains a systematic share repurchase program, 
which is intended to offset the dilutive effect of shares issued
for employee benefit plans. The company did not reacquire any
shares of its common stock for this program in 1995; however,
364,000 shares were reacquired in 1994 and 449,000 shares were
reacquired in 1993 through open and private market purchases. The

               TO CONSOLIDATED FINANCIAL STATEMENTS

company anticipates that it will continue to periodically
reacquire shares under its systematic share repurchase program.

   In June 1995, the company purchased approximately 3.5 million
shares (approximately 5 percent of total outstanding shares) of
its common stock at a price of $25.00 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. In addition, the company
may purchase approximately 2.5 million additional shares from
time to time through open market and privately negotiated
transactions to complete the remaining portion of a 6 million
share repurchase program.

11. RENTALS AND LEASES
- --------------------------------------------------------------------------------
The company leases sales office and distribution center
facilities, automobiles and computer and other equipment under
operating leases. Rental expense under all operating leases was
$32,292,000 in 1995, $29,129,000 in 1994 and $29,325,000 in 1993.
As of December 31, 1995, future minimum payments under operating
leases with noncancelable terms in excess of one year were:

Research expenditures which related to the development of new
products and processes, including significant improvements and
refinements to existing products, were $28,031,000 in 1995,
$27,615,000 in 1994 and $24,782,000 in 1993.

13. ENVIRONMENTAL COMPLIANCE COSTS
- --------------------------------------------------------------------------------
The company and certain subsidiaries are party to various
environmental actions which 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 and
results of operations 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.

14. GEOGRAPHIC SEGMENTS

              MANAGEMENT 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.

We have audited the accompanying consolidated balance sheet of
Ecolab Inc. as of December 31, 1995, 1994 and 1993, 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, 1995, 1994
and 1993, and the consolidated results of its operations and its
cash flows for the years then ended in conformity with generally
accepted accounting principles.

   As discussed in Note 7 to the consolidated financial statements,
effective January 1, 1993, the company adopted Statement of
Financial Accounting Standards No. 109, "Accounting for Income
Taxes."

Pro forma results 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 1993 and 1986 two-for-one stock
splits. The ratios of return on beginning equity and
dividends/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.
