                                        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
balance sheet accounts, revenues and expenses.  Financial statements of the
Henkel-Ecolab Joint Venture as listed under Item 14, I(3) of Part IV hereof are
included as a part of this Report.  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.

Effective at the end of 1997, the Company acquired the outstanding shares of
Gibson Chemical Industries Limited ("Gibson") headquartered in Melbourne,
Victoria, Australia for a purchase price of approximately A$192,000,000.  Gibson
is engaged principally in the supply of cleaning and sanitation chemicals and
services to the hospitality and healthcare industries and to catering
institutions and the supply of specialty chemicals and services to major
manufacturing and mining industries.  Its manufacturing and/or distribution
operations are located primarily in Australia and New Zealand, with smaller
operations in Southeast Asia, the United Kingdom and the United States.  The
acquisition of Gibson will substantially increase the Company's operations in
the Asia Pacific region.

ITEM 1(b) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

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

                                         -2-


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, quickservice (fast-food and other
convenience store units), commercial and institutional laundries, 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 in order to meet a full range of cleaning and sanitation needs.
Distributors are utilized in several markets, as described in the business unit
descriptions located under the heading "Business Divisions."

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 are
purchased from third party suppliers.  Additional information on the Company's
manufacturing facilities is located under Item 2 below under the heading
"Properties."

In the United States and Canada, the Company operates through seven divisions:
Institutional, Kay, Food and Beverage, Pest Elimination, Textile Care,
Professional Products 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
and the extent and nature of such international businesses varies by location;
however, these businesses are expanding into a number of international
locations.  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.

The Company conducts business in approximately 35 countries outside of the
United States through wholly-owned subsidiaries, or, in the case of Venezuela,
China, and Indonesia, through majority- owned joint ventures with local
partners.  In  other countries, selected products are sold by distributors,
agents or licensees, although those sales are not significant in terms of the
Company's overall sales.  The largest international operations are located in
Asia Pacific, Latin America and Canada with smaller start-up operations in
Africa.  For the year ended December 31, 1997, international sales comprised
approximately 22 percent of the Company's total consolidated net sales.  For
purposes of public financial reporting, international operations include Canada,
but on an operational basis, the businesses in Canada are, in general, operated
together with United States businesses as a part of North American operations.

BUSINESS DIVISIONS

The following descriptions of the Company's North American divisions include a
discussion, where applicable, of similar businesses currently conducted
elsewhere internationally.  The Company pursues a "Circle the Customer - Circle
the Globe" strategy by developing relationships and

                                         -3-


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.  In some circumstances, the business of the Company's
divisions, or of the business units within the divisions, may be conducted by
one or more subsidiaries of the Company.

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.  By the acquisition of certain assets of Grace-Lee
Products in late 1997, the Division also entered the vehicle wash industry.  The
Institutional Division also markets various chemical dispensing device systems,
which are made  available to customers, to dispense the Company's cleaners and
sanitizers.  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, rinse additives and
sanitizers including full machine maintenance.  Similar dishwashing machines and
other customized equipment is sold to third parties through the Company's
Jackson line.  The Division's warewashing, on-premise laundry and housekeeping
businesses are, in general, conducted in all international locations but may be
tailored to meet unique local needs.  The other businesses are concentrated in
North America and offered less extensively internationally.

The Company believes it is the leading supplier of chemical warewashing products
to institutions in the United States and Canada and, including the Henkel-Ecolab
Joint Venture in Europe, is one of the leading suppliers worldwide.

The Institutional Division sells its products and services primarily through
Company-employed field sales and service personnel.  The Company also utilizes
food-service distributors to market and sell its products to smaller accounts or
accounts which purchase through food distributors and the Company provides the
same service to accounts served by food distributors as to direct customers.

KAY:  The Kay Division supplies chemical cleaning and sanitizing products
primarily to the quick-service restaurant industry.  This includes traditional
fast food restaurants but, increasingly, other places where "fast food" is
prepared and served such as convenience stores, airport and shopping center
kiosks, discount stores, stadiums, grocery store delis and other venues.  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.
In addition, Kay supports its product sales with employee training programs and
technical support designed to meet the special needs of its customers which have
a relatively high employee turnover.  Kay's customized cleaning and sanitation
programs are designed to reduce labor costs and product usage while increasing
sanitation levels, cleaning performance, equipment life and safety levels.

Kay employs a direct field sales force which primarily calls upon national and
regional quick service restaurant chains and franchisees, although the sales are
made to distributors who supply the chain or franchisee's restaurants.

Kay sales are primarily in the United States but international sales have grown
as United States-based customers have expanded into international markets.
Because a significant portion of Kay's international sales are to non-United
States units of United States-based quickservice restaurant

                                         -4-


chains, a substantial portion of Kay's international sales are made either to
domestic or internationally located distributors who service these chains.

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

FOOD AND BEVERAGE:  The Food and Beverage Division addresses cleaning and
sanitation at the start of the food chain to facilitate the production of
products safe for human consumption.  The Division 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.  Food and Beverage businesses are
operated 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 Pest Elimination business
acquires most of its insecticides and pesticides from third-party vendors.  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 but also operates in Puerto Rico,
Hong Kong and New Zealand, as well as parts of Canada and Mexico.

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 and include free-standing laundry plants used by institutions
such as hotels, restaurants and healthcare facilities as well as industrial,
textile rental and shirt laundries.  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 Division's programs are designed to meet the
customer's need for exceptional cleaning, while extending the useful life of
linen and reducing the customer's overall operating cost.  Textile Care
offerings complement the Institutional Division's offerings to small-to-medium
size on-premise laundry facilities.  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.

PROFESSIONAL PRODUCTS:  The Professional Products Division provides a full line
of infection control and janitorial offerings that are sold to the medical and
janitorial markets in the United States and Canada.  The Professional Products
Division sells its proprietary products under the brand names

                                         -5-


Airkem (detergents, general purpose cleaners, carpet care, furniture polishes,
disinfectants, floor care products, hand soaps and odor counteractants) and
Huntington (infection control and gym floor products).

The Company believes it is among the largest suppliers of infection-control and
general cleaners to the United States healthcare industry as well as one of the
market leaders in the overall North American janitorial market.  Products are
sold in the United States and Canada through a Company-employed sales force as
well as a network of independent distributors in both janitorial and medical
markets who sell products and services to the institutional, healthcare 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.  In addition, the Division,
through its JaniSource operation, markets brand name products for sale through
mass commercial distribution networks.  Similar businesses are conducted on a
limited basis in other international markets, primarily Brazil and South Africa.

WATER CARE SERVICES:  The Water Care Services Division expands the Company's
"Circle the Customer - Circle the Globe" strategy by adding an offering which is
critical to companies in the Company's customer base--water treatment programs.
The Water Care Services Division provides water and wastewater treatment
products, services and systems for commercial/institutional customers
(hospitals, healthcare, commercial real estate, government, shopping malls and
commercial laundries) and light industry (food and beverage accounts, textile
mills, electronic plants and other industries).  As a facet of its growth
strategy, Water Care Services works closely with the Company's Institutional,
Textile Care and Food and Beverage Divisions to offer customized water care
strategies to their accounts that have water care needs, primarily to treat
water used in heating and cooling systems and manufacturing processes and to
treat waste water.  In selected United States markets, the Division also
provides pool and spa treatment programs for commercial and hospitality
customers.  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'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 which focus 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 and differentiated products.  Value is provided by
state-of-the-art, environmentally-compatible cleaning, sanitation and
maintenance 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 Company's significant on-going investment in training
and technology development and by the Company's standard practice of assisting
customers in lowering operating costs and complying with safety, environmental
and sanitation regulations.  In addition, the Company emphasizes its ability to
uniformly provide a variety of related premium cleaning and sanitation services
to its customers and to provide that level of service to multiple

                                         -6-


locations of chain customer organizations worldwide.  This approach is
succinctly stated in the Company's "Circle the Customer - Circle the Globe"
strategy.

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 common
carriers, its own delivery vehicles and distributors.  Additional information on
the Company's plant and distribution facilities is located under Item 2 below
under the heading "Properties."

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 quickservice chains and franchisees.  No material part of the
Company's business is subject to renegotiation or termination at the election of
a governmental unit.  The Company sells two classes of products which each
constitute 10 percent or more of its sales.  Worldwide sales of warewashing
products in 1997, 1996 and 1995 approximated 31, 31 and 33 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 3 hereof.  Total
laundry sales in 1997, 1996 and 1995 approximated 14, 14 and 15 percent
respectively, of the Company's consolidated net sales.

The Company's business has little seasonality.

The Company has invested in the past, and will continue to invest in the future,
in merchandising equipment consisting primarily of systems used by customers to
dispense the Company's cleaning and sanitizing products.  The Company,
otherwise, has no unusual working capital requirements.  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.

                                         -7-


FORWARD-LOOKING STATEMENTS AND RISK FACTORS

The Private Securities Litigation Reform Act of 1995 provides a safe harbor for
forward-looking statements.  From time to time, in written reports (including
reports to the Securities and Exchange Commission, press releases and reports to
shareholders among others) and oral statements, the Company or its Management
discusses expectations regarding future performance of the Company including
anticipated financial performance, business prospects, acquisition programs, new
products, research and development activity, plans for international expansion,
capital expenditures and similar matters.  Without limiting the foregoing, words
or phrases such as "will likely result," "are expected to," "will continue," "is
anticipated," "we believe," "estimate," "project" (including the negative or
variations thereof) or similar terminology, generally identify forward-looking
statements.

Forward-looking statements represent challenging goals for the Company.  As
such, they are based on certain assumptions and estimates and are subject to
certain risks and uncertainties.  The Company cautions that undue reliance
should not be placed on such forward-looking statements which speak only as of
the date made.  In order to comply with the terms of the safe harbor, the
Company hereby identifies important factors which could affect the Company's
financial performance and could cause the Company's actual results for future
periods to differ materially from the anticipated results or other expectations
expressed in the forward-looking statements.  These factors should be
considered, together with any similar risk factors or other cautionary language
which may be made in connection with, or at the time of, the making of the
forward-looking statement, or in other filings with the Securities and Exchange
Commission.

Risks and uncertainties that may affect operating results and business
performance include:  pricing flexibility; availability of adequate and
reasonably-priced raw materials; the occurrence of capacity constraints limiting
the production of certain products; ability to carry out the Company's
acquisition strategy, including difficulties in rationalizing acquired
businesses and in realizing related cost savings and other benefits; the costs
and effects of "year 2000" computer software issues (described below); the costs
and effects of complying with:  (i) the significant environmental laws and
regulations which apply to the Company's operations and facilities, (ii)
government regulations relating to the manufacture, storage, distribution and
labeling of the Company's products and (iii) changes in tax, fiscal,
governmental and other regulatory policies; economic factors such as the
worldwide economy, interest rates, currency movements and the development of
markets; the occurrence of (i) litigation or claims, (ii) natural or man-made
disasters and (iii) severe weather conditions affecting the food service and
hospitality industry; loss of, or changes in, executive management; the
Company's ability to continue product introductions and technological
innovations; and other uncertainties or risks reported from time-to-time in the
Company's reports to the Securities and Exchange Commission.  In addition, the
Company notes that its stock price can be affected by fluctuations in quarterly
earnings.  Despite favorable year-over-year quarterly comparisons in recent
years, there can be no assurances that earnings will continue to improve or that
the degree of improvement will meet investors' expectations.

The "year 2000" issue is the result of computer programs having date-sensitive
software which may recognize a date using 00 as the year 1900 rather than the
year 2000.  If not detected and corrected, this can result in system failure or
miscalculations causing disruptions of operations, including a temporary
inability to process transactions, send invoices, or engage in similar normal
business activities.  Accordingly, the failure to resolve year 2000 issues could
have a material impact on the Company.  The Company has put in place plans and
processes which it believes will be sufficient

                                         -8-


to evaluate and manage risk associated with year 2000 issues and will use both
internal and external resources.  However, estimates of year 2000 costs, time
schedules and the Company's belief that it can successfully resolve year 2000
issues are based on presently available information and are subject to certain
assumptions and risks.  These include the availability of necessary and trained
personnel who can be hired or retained on a contract basis, the ability to
locate and correct all relevant computer codes and uncertainties surrounding the
ability of suppliers and vendors to resolve their year 2000 issues.  The ability
of governmental agencies to resolve year 2000 issues is an additional risk and
uncertainty.  However, although such risks and uncertainties exist, the Company
believes that its exposure to year 2000 issues is not dissimilar to that of
other companies engaged in similar businesses.

This summary of risks and uncertainties supersedes the summary provided in the
Company's Current Report on Form 8-K dated February 20, 1998.

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, development and engineering
personnel.  Note 12, entitled "Research Expenditures" located on page 47 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, 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.  Although the Company is not currently aware of any such
circumstances, 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.

PHOSPHOROUS 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

                                         -9-


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.  Phosphorous 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" or "antimicrobial pesticides" under the current
definitions of the Federal Insecticide Fungicide and Rodenticide Act ("FIFRA"),
as amended by the Food Quality Protection Act of 1996, the principal federal
statute governing the manufacture, labeling, handling and use of pesticides.
Approximately 280 of these products must be registered with the United States
Environmental Protection Agency ("EPA").  Registration entails the necessity to
meet certain efficacy, toxicity 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 certain other states have
regulatory schemes under consideration.  In addition, California imposes a tax
on total pesticide sales in that state.  While the cost of complying with rules
as to pesticides has not had a material adverse effect on the Company's
financial condition, liquidity or the results of its operations to date, the
costs and delays in receiving necessary approvals for these products have
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, were approximately
$1,200,000 in 1997.  Such costs will increase somewhat in 1998, but not in
amounts which are expected to significantly affect the Company's results of
operations, liquidity or consolidated financial condition.

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 1997 were approximately $942,000 and approximately
$1,500,000 has been budgeted for 1998.  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

                                         -10-


Environmental Response, Compensation and Liability Act ("CERCLA") or state
equivalents at 15 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 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 PRPs will work
with the EPA to agree and implement a plan for site remediation.

In addition to the 15 sites noted above, the Illinois Environmental Protection
Agency ("Agency"), in 1996, identified the Company, along with two other
corporations, as PRPs in connection with groundwater contamination near the
Company's South Beloit, Illinois manufacturing facility.  The Agency has
requested that the U.S. Environmental Protection Agency place the site on the
National Priority List of federal superfund sites.  The Agency is seeking a
potable water supply for approximately 200 homes at the Evergreen Manor
residential subdivision, an investigation of the source and extent of the
contamination, remedial cleanup and reimbursement of the state's costs.  The
Company has denied liability and has requested that the Agency withdraw its
identification of the Company as a PRP.

Based on an analysis of the Company's experience with such environmental
proceedings, the Company's estimated share of all hazardous materials deposited
on the 16 sites referred to in the two preceding paragraphs, and the Company's
estimate of the contribution to be made by other PRPs which the Company believes
have the financial ability to pay their shares, the Company has accrued its best
estimate of the Company's future costs relating to such known sites.

Also, the Company is involved in certain continuing groundwater clean-up
activities as required by New Jersey environmental authorities at a property
owned by the Company.  The Company has worked with appropriate authorities to
resolve the issues involved and has accrued its best estimate of future costs
relating to the site.

The New South Wales (Australia) Environmental Protection Authority has
identified a property owned by Maxwell Chemicals Pty Limited, a subsidiary of
the Company, as impacted by contamination.  Because a remedial action plan has
not yet been completed for the site, remedial costs cannot be predicted but the
Company believes the cost will not be material.

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 clean-up 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 clean-up are less than that claimed by the
government.  The Company has agreed to indemnify 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 1997, the Company's net expenditures for contamination remediation were
approximately $300,000.  The accrual at the end of 1997 for future remediation
expenditures was approximately $10,000,000.  The Company reviews its exposure
for contamination remediation costs periodically

                                         -11-


and its accruals are adjusted as considered appropriate.  In establishing
accruals, potential insurance reimbursements are not included.  While the final
resolution of these issues could result in costs below or above current accruals
and, therefore, have an impact on the Company's consolidated financial results
in a future reporting period; the Company believes the ultimate resolution of
these matters will not have a significant effect on the Company's consolidated
financial position or liquidity or, on an on-going basis, its results of
operations.

In addition, the Company has retained responsibility for certain sites where the
Company's former ChemLawn business is a PRP.  Currently there are eight such
locations and, at each, ChemLawn is a de minimis party.  Anticipated costs
currently accrued for these matters were included in the Company's loss from its
discontinued ChemLawn operations in 1991.  The accrual remaining reflects
management's best estimate of future costs.

NUMBER OF EMPLOYEES

The Company currently has approximately 10,210 employees worldwide.

ITEM 1(d) FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT
SALES

The financial information appearing under the heading "Geographic Segments" in
Note 14, located on page 47 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.  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.

ITEM 2.  PROPERTIES

The Company's manufacturing facilities produce chemical products or equipment
for all the Company's businesses, although the Pest Elimination Division
purchases most of its products and equipment from outside suppliers.  The
Company's chemical production process consists primarily of blending and
packaging powders and liquids and casting solids.  The Company's equipment
manufacturing operations consist primarily of producing chemical product
dispensers and ejectors and other mechanical equipment (South Beloit, Illinois),
dishwasher racks and related sundries (Elk Grove Village, Illinois and Shika,
Japan) and dishwashing machines, a portion of which is sold to third party
dishwashing machine distributors (Barbourville, Kentucky).  The Company's
philosophy is to manufacture products wherever an economic, process or quality
assurance advantage exists or where proprietary manufacturing techniques dictate
internal production processes.  Currently most products used by the Company are
manufactured at Company facilities.

The following chart profiles the Company's manufacturing facilities which are
approximately 50,000 square feet or larger in size.

Additional United States manufacturing facilities owned by the Company are
located in North Kansas City, Missouri; Grand Forks, ND and Dallas, Texas.  The
Company also operates smaller international manufacturing facilities in
Argentina; Australia; Chile; Costa Rica; Fiji; Indonesia; Japan; New Zealand;
Papua New Guinea; People's Republic of China; Philippines; Puerto Rico;
Singapore; South Korea; Tanzania and Thailand.

The Company believes its manufacturing facilities are in good condition and are
adequate to meet existing production needs.

Most of the Company's manufacturing plants also serve as distribution centers.
In addition, around the world, the Company operates distribution centers, all of
which are leased, and utilizes various public warehouses to facilitate the
distribution of its products and services.  In the United States, the Company's
sales associates are located in approximately 139 leased offices. Additional
sales offices are located internationally.

The Company's corporate headquarters is comprised of three multi-storied
buildings located in downtown St. Paul, Minnesota.  The main 19-story building
was constructed to the Company's specifications and is leased through 2003.
Thereafter, it is subject to multiple renewals at the Company's option.  Another
building is owned.  The third building is also subject to a long-term lease by
the Company.  In 1997, the Company began an extensive renovation and expansion
of the corporate headquarters which will include a state-of-the-art training
center and facilities to add several hundred additional jobs at the Company's
headquarters.  The Company also owns a computer center in St. Paul and a
research facility and chemical pilot plant both of which are located in suburbs
of St. Paul.

ITEM 3.  LEGAL PROCEEDINGS

Proceedings arising under laws relating to protection of the environment are
discussed at Item 1(c) above, under the heading "Environmental Considerations."

As previously reported in the Company's Form 10-Q for the quarter ended
September 30, 1997, the legal action commenced by ten distributors of the
Company's Airkem janitorial products was reduced in scope by summary judgment
rendered by the Court in April 1997 in favor of the Company.  Two claims
remained pending.  Subsequently, the legal action was divided into separate

                                         -16-


trials for each of the plaintiff distributors.  The first trial took place in
May-June 1997, with a jury verdict in favor of the plaintiff in the amount of
$29,000 on one of the claims, and a verdict in favor of the Company on the
second claim.  That part of the jury's decision favoring the plaintiff has been
appealed by the Company.  Prior to trial, the Company settled the claims of two
of the plaintiffs on a basis not material to the Company.  The trials of the
other seven plaintiffs will likely be scheduled for later in 1998.  Those
plaintiffs may also appeal the Court's summary judgment decision.

The Company and certain of its subsidiaries are defendants in various other
lawsuits and claims arising out of the normal course of business.  Accruals have
been established reflecting management's best estimate of future costs relating
to such matters and, in the opinion of management, the ultimate resolution of
this litigation will not have a material effect on the Company's results of
operations, consolidated financial condition or liquidity.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

A Special Meeting of the Stockholders was held on October 22, 1997.  At the
meeting, 91.6 percent of the outstanding shares of the Company's voting stock
was represented in person or by proxy.  The sole proposal voted upon was to
amend and restate the Company's Restated Certificate of Incorporation to
increase the authorized Common Stock of the Company from 100,000,000 shares to
200,000,000 shares.  The increase in the authorized capital was approved as
follows (there were no broker non-votes):

                             INDEPENDENT AUDITORS' REPORT


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 audits 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.

                                         -32-



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 1997, 1996, 1995 and the results of its
operations and its cash flows for the periods beginning December 1, 1996, 1995
and 1994, and ended November 30, 1997, 1996 and 1995 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.


                                         -39-


The Joint Venture enters into foreign currency forward and option contracts 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 totaled TDM 4,599 in
1997, TDM 4,479 in 1996 and TDM 3,494 in 1995.

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 this 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 3,200 at
November 30, 1997, TDM 3,948 at November 30, 1996 and TDM 4,696 at November 30,
1995.  The market value of the investment cannot be determined.


                                         -40-


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:

Buildings 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
exceeded 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 11,188 in 1997, TDM 12,588 in 1996 and TDM
7,469 in 1995.

USE OF ESTIMATES

The preparation of financial statements requires management to make estimates 
and assumptions that affect the reported amounts of assets and liabilities, 
as well as disclosure of contingent assets and liabilities at the date of the 
financial statements and the reported amounts of revenues and expenses during 
the reporting period.  Actual results may differ from those estimates.

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 at agreed upon prices as defined
by an annual supply plan submitted to the related manufacturing facility.
Purchases totalled TDM 221,341 in 1997, TDM 232,581 in 1996 and TDM 239,819 in
1995.

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 14,807 in
1997, TDM 14,228 in 1996 and TDM 20,356 in 1995.

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 24,372 in 1997, TDM 22,718 in 1996 and TDM
28,180 in 1995.

                                         -43-


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 3.625 % per November 30, 1997 and 3.80 % for 3 month
short term German Marks loans per November 30, 1997); on overdrafts,
approximately between 0.5 - 1.25 percentage point is paid to compensate Henkel
for administration costs.

At November 30, 1997 the Joint Venture had borrowed TDM 1,159, from Henkel Group
Companies, TDM 7,445 in 1996 and TDM 48,437 in 1995. The loans receivable from
Henkel Group Companies had totalled TDM 6,894 in 1997, TDM 8,007 in 1996 and TDM
15,778 in 1995. The fair values of intercompany loans receivable and payable
approximate book value.

Interest expense to related companies totalled TDM 1,302 in the year ended
November 30, 1997, TDM 1,463 in 1996 and TDM 6,235 in 1995. Interest income from
related companies amounted to TDM 982 for the year ended November 30, 1997, TDM
1,180 in 1996 and TDM 3,251 in 1995.

During 1997 the Joint Venture began to charge the parents for certain costs 
incurred on behalf of the parents which by their nature are not arm's length. 
The Joint Venture has reflected such costs in the amount of TDM 1,515 as 
contributed capital.

4. INCOME TAXES

The provision for income taxes totalled TDM 51,267, compared to November 30,
1996 TDM 45,334 and November 30, 1995 TDM 31,637. The net deferred taxes
included in the provision for income taxes for 1997 were TDM 3,509 credit, for
1996 TDM 1,366 debit and for 1995 TDM 624 credit.

The components of the Joint Venture's overall net deferred tax asset at November
30, 1997, at November 30, 1996 and at November 30, 1995 are as follows:

At November 30, 1997, the Joint Venture had net foreign operating loss
carryforwards for tax purposes of approximately TDM 30,987 compared to November
30, 1996 TDM 27,535 and compared to November 30, 1995 TDM 25,163. A significant
portion of these losses have an indefinite carryforward period; the remaining
losses have expiration dates up to five years.

                                         -45-


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,
1997.

A reconciliation of the statutory German trade tax and federal corporate 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.

In 1997, the tax payments were TDM 32,756, in 1996 TDM 19,128 and in 1995 TDM
24,503.

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 all the components of net periodic pension cost concerning the
plans in Germany, Belgium, the Netherlands, Great Britain and Austria for the
twelve months ended November 30, 1997, 1996 and 1995 follows (TDM):

The following assumptions have been used to develop net periodic pension expense
and the actuarial present value of projected benefit obligations:






                               1997             1996          1995

Pursuant to the provisions of Statement of Financial Accounting Standards No.
87, "Employer's Accounting for Pensions", the Joint Venture recorded an
additional minimum pension liability adjustment of TDM 3,487 as of November 30,
1997, representing the amount by which the accumulated benefit obligation
exceeded the accrued pension liability for the German plans. The additional
liability is offset by an intangible asset recorded under "Intangible and Other
Assets, net" as of November 30, 1997.

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

6. TOTAL INDEBTEDNESS

Short Term Debt

As of November 30, 1997 short term debt totalled TDM 24,318  compared to
November 30, 1996 TDM 72,972 and compared to November 30, 1995 TDM 17,695,
generally in short term credit line facilities with interest rates based on
local money market rates. As of November 30, 1997 the three main balances are in
Italian Lira in the equivalent amount of TDM 7,669 at an interest rate of 6.67 %
p.a., in Dutch Guilders in the equivalent amount of TDM 7,099 at an interest
rate of 4.05 % p.a. and in Spanish Peseta in the equivalent amount of TDM 2,687
at an interest rate of 7.9 % p.a..

The total long term debt amount is borrowed in Danish Krona at an average
interest rate of 10.15 % p.a.. As of November 30, 1997, the aggregate annual
maturities of long term debt were:

1998 - TDM   656              1999 - TDM   656
2000 - TDM   164              2001 - TDM 3,940

Interest expense related to all debt was TDM 6,146 in 1997, compared to November
30, 1996 TDM 4,133 and compared to November 30, 1995 TDM 4,329. 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 30,1997         November 30,1996

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 and option contracts 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 month 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, 1997 (TDM):




                           
               1998           24,014
               1999           19,147
               2000           12,246
               2001            5,668
               2002            5,315
               thereafter      6,078
                              ------

               Total          72,468
                              ------
                              ------


Rent expense for the twelve month period ended November 30, 1997, was
approximately TDM 27,416, compared to November 30, 1996 approximately TDM 18,503
and compared to November 30, 1995 approximately TDM 17,790.

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.

                                         -53-


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

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
1997, 1996 and 1995, and there were no significant accounts receivable from a
single customer at November 30, 1997, 1996 and 1995. The Joint Venture
establishes an allowance for doubtful accounts based upon factors surrounding
the credit risk of specific customers, historical trends and other information.
