                                        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.

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, quickservice (fast-food 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.  Distributors are utilized in several markets, as described


                                        - 2 -

<PAGE>

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,
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, Pest Elimination, Textile Care,
Professional Products (formerly Janitorial Division) 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 expanding into a number
of international locations.
  
The Company conducts business in approximately 30 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 or
agents, although those sales are not significant in terms of the Company's
overall sales.  For the year ended December 31, 1996, international sales
comprised approximately 23% 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 divisions include a discussion,
where applicable, of similar businesses 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 made  available 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


                                        - 3 -

<PAGE>

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 Institutional 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 supplies chemical cleaning and sanitizing products
primarily to the quick-service restaurant and grocery industries.  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 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 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 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


                                        - 4 -

<PAGE>

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 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.  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 janitorial and infection control offerings that include odor counteractants,
disinfectants, floor care and carpet care systems, hand care products and
general cleaners and medical instrument sterilants which are sold to the medical
and janitorial markets in the United States and Canada.  In 1996, the  Company
acquired Huntington Laboratories, Inc., a supplier of infection control products
and gym floor finishes which it integrated into its janitorial business.  The
Division, which was previously called the Janitorial Division, was renamed
following the Huntington acquisition to the Professional Products Division to
better reflect its expanding business.

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.  Infection-control and janitorial
products are also sold on a limited basis in other international markets.

WATER CARE SERVICES:  The Water Care Services Division, which in 1997 will be in
its third year as a separate Company 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 institutional, commercial and light industrial
customers.  Operations are presently concentrated in North America, where the
Company has acquired four existing water care businesses since late 1994.  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 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


                                        - 5 -

<PAGE>

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.  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
significant on-going 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.  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 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


                                        - 6 -

<PAGE>

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 1996, 1995 and 1994
approximated 31, 33 and 35 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 1996, 1995 and 1994
approximated 14, 15 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.  

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, 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


                                        - 7 -

<PAGE>

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.  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. 
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 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, were approximately
$1,269,000 in 1996.  Such costs will increase somewhat in 1997, but not in
amounts which are expected to significantly affect the Company's results of
operations, consolidated financial condition or liquidity.  The new Food Quality
Protection Act is expected to accelerate the pace at which the Company obtains
future product registrations.

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


                                        - 8 -

<PAGE>

its results of operations.  The Company's capital expenditures for environmental
control projects incurred for 1996 were approximately $1,090,000 and
approximately the same level of expenditure has been budgeted for 1997.  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 11 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 11 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 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 12 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 site used 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.

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 1996, the Company's net expenditures for contamination remediation were
approximately $200,000.  The accrual at the end of 1996 for future remediation
expenditures was approximately $9,800,000.  The Company reviews its exposure for
contamination remediation costs periodically and its accruals are adjusted as
considered appropriate.  In establishing accruals, potential insurance


                                        - 9 -

<PAGE>

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 9,500 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 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.

ITEM 2.  PROPERTIES

The Company's manufacturing facilities produce chemical products or equipment
for all the Company's businesses except the Pest Elimination Division which
purchases products and substantially all its 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 United States plant facilities devoted primarily to the production
of chemical products are located in Joliet, Illinois; Avenel, New Jersey;
McDonough, Georgia; Garland, Texas; San Jose, California; Hebron, Ohio; and City
of Industry, California.  Smaller plant facilities in North Kansas City,
Missouri; Charlotte, North Carolina; Huntington, Indiana; and Grand Forks, North
Dakota produce certain chemical products primarily for the Company's Textile
Care, Water Care Services, Food and Beverage and Professional Products
divisions.  These facilities except for those located in Kansas City and
Charlotte are Company-owned.  The Company's Kay business also owns and operates
manufacturing facilities in Greensboro, North Carolina and Dallas, Texas.

Additional chemical manufacturing facilities are located in Dorado, Puerto Rico;
Santa Cruz, Brazil; Hamilton, New Zealand; Noda and Shika, Japan; Sydney and
Melbourne, Australia; Seoul, South Korea; Mexico City, Mexico; Bangkok,
Thailand; Toronto, Canada; and Johannesburg, South Africa.  The buildings and
land for the facilities located in Canada, Australia and Puerto Rico are leased.
A chemical plant, which is co-owned with a Chinese joint venture partner, is
located near Shanghai, People's Republic of China, and a leased chemical plant
is located in Chile.  Smaller chemical plant facilities are owned in certain
other locations including Costa Rica; Brisbane, Australia; Singapore; Jakarta,
Indonesia and Dar es Salaam, Tanzania.

The Company's plant in South Beloit, Illinois produces chemical product
dispensers and injectors and other mechanical equipment.  A leased plant, which
manufactures dishwasher racks and related sundries, is located in Elk Grove
Village, Illinois.  Dishwasher racks are also produced at the Shika, Japan
plant.  Dishwashing machines which are used in the Company's Ecotemp operations
are manufactured in an owned facility in Barbourville, Kentucky.  The
Barbourville facility also


                                        - 13 -

<PAGE>

produces a portion of its machines for sale to third party dishwashing machine
distributors.  A leased facility in Memphis, Tennessee serves as a dishwashing
machine refurbishing center.

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 125 leased offices. Additional
sales offices are located internationally.

The Company's corporate headquarters is located in downtown St. Paul, Minnesota.
The 19-story building was constructed to the Company's specifications and is
leased through 1998.  Thereafter, it is subject to multiple renewals at the
Company's option.  The Company also owns a building in downtown St. Paul
adjacent to its headquarters.  Recently, the Company unveiled plans for an
expansion of its downtown St. Paul headquarters.  The plan includes a long-term
lease of another adjacent building and extensive renovations.  The expansion is
expected, over time, to bring several hundred additional jobs to the Company's
headquarters and will include a state-of-the-art corporate employee training
center.  The Company also owns a research and development facility and a
chemical pilot plant which are located in suburbs of St. Paul as well as a
computer center located in St. Paul, several blocks from the Company's
Headquarters.

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."

A legal action commenced by ten distributors of the Company's Airkem 
janitorial products ("Plaintiffs") in 1995 in Minnesota State Court, Hennepin 
County, remains pending.  Plaintiffs allege a variety of claims, including 
breach of contract, fraud, breach of Minnesota's antitrust statute and 
various other State statutes.  The claims center around the process under 
which these distributors converted from exclusive to non-exclusive, as well 
as challenges to the Company's national account program.  Plaintiff's damages 
claim has varied, ranging from $22,000,000 to $37,000,000.  The Company has 
denied liability and believes the allegations are substantially without 
merit.  Trial is scheduled for May, 1997.  Plaintiffs' claims are not covered 
by the Company's insurance.

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

No matters were submitted to a vote of security holders, through the

                          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.

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, 1996, 1995 and 1994, and the results of its
operations and its cash flows for the periods beginning December 1, 1995, 1994
and 1993, and ended November 30, 1996, 1995 and 1994, 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 4,479 in
1996, TDM 3,494 in 1995 and TDM 3,877 in 1994.

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 3,948 at
November 30, 1996, TDM 4,696 at November 30, 1995 and TDM 5,444 at November 30,
1994. 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:

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 12,588 in 1996, TDM 7,469 in 1995 and TDM
6,407 in 1994.

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 indu-strial 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 232,581 in 1996, TDM 239,819
in 1995 and TDM 259,882 in 1994.

Henkel also with a declining degree 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 14,228 in 1996, TDM 20,365 in 1995 and TDM 20,326 in
1994.

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 22,718 in 1996, TDM 28,180 in 1995 and TDM
31,874 in 1994.

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 4.5 % per November 30, 1996 and 4.0 % for 3 month short
term German Marks loans per November 30, 1996); on overdrafts, approximately
between 1.0 - 1.5 percentage point is paid to compensate Henkel for
administration costs.

At November 30, 1996 the Joint Venture had borrowed TDM 7,445, from Henkel Group
Companies, TDM 48,437 in 1995 and TDM 63,810 in 1994. The loans receivable from
Henkel Group Companies had totalled TDM 8,007 in 1996, TDM 15,778 in 1995 and
TDM 38,140 in 1994. The fair values of intercompany loans receivable and payable
approximate book value.

Interest expense to related companies totalled TDM 1,463 in the year ended
November 30, 1996, TDM 6,235 in 1995 and TDM 6,204 in 1994. Interest income from
related companies amounted to TDM 1,180 for the year ended November 30, 1996,
TDM 3,251 in 1995 and TDM 1,989 in 1994.

4. INCOME TAXES

The provision for income taxes totalled TDM 45,334, compared to November 30,
1995 TDM 31,637 and November 30, 1994 TDM 36,287. The net deferred taxes
included in the provision for income taxes for 1996 were TDM 1,366 debit, for
1995 TDM 624 credit and for 1994 TDM 1,993 credit.

The components of the Joint Venture's overall net deferred tax asset at November
30, 1996, at November 30, 1995 and at November 30, 1994 are as follows:

At November 30, 1996, the Joint Venture had net foreign operating loss
carryforwards for tax purposes of approximately TDM 27,535 compared to November
30, 1995 TDM 25,163 and compared to November 30, 1994 TDM 17,847. A significant
portion of these losses have an indefinite carryforward period; the remaining
losses have expiration dates up to five years.

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,
1996.

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 1996, the tax payments were TDM 19,128, in 1995 TDM 24,503 and in 1994 TDM
21,368.

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, 1996, 1995 and 1994 follows (TDM):

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 30,1996         November 30,1995
                        ----------------         ----------------

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


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.

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, 1996 (TDM):

              1997                16,089
              1998                11,591
              1999                 7,433
              2000                 4,764
              2001                 4,128
              thereafter           7,802
                                  ------

              Total               51,807
                                  ------
                                  ------

Rent expense for the twelve month period ended November 30, 1996, was
approximately TDM 18,503, compared to November 30, 1995 approximately TDM 17,790
and compared to November 30, 1994 approximately TDM 16,372.

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 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
1996, 1995 and 1994, and there were no significant accounts receivable from a
single customer at November 30, 1996, 1995 and 1994. The Joint Venture
establishes an allowance for doubtful accounts based upon factors surrounding
the credit risk of specific customers, historical trends and other information.

                        RESTATED CERTIFICATE OF INCORPORATION 
                                          OF
                                     ECOLAB INC. 

                             (Originally incorporated as
                            Economics Laboratory, Inc. on
                                  February 18, 1924)

                                      ARTICLE I

The name of the Corporation is ECOLAB  INC.

                                      ARTICLE II

The purposes of the Corporation are to engage in any lawful act or activity for
which corporations may be organized under the General Corporation Law of
Delaware, and without limiting the foregoing, to hold shares of the capital
stock of other corporations and to engage in services of all kinds, and produce,
manufacture, develop, construct, transport, buy, hold, sell and generally deal
in products, materials and property, both tangible and intangible.

                                     ARTICLE III

The total number of shares of all classes of capital stock which the Corporation
shall have authority to issue is one hundred fifteen million (115,000,000)
consisting of one hundred million (100,000,000) shares of Common Stock of the
par value of One Dollar ($1.00) per share and fifteen million (15,000,000)
shares of Preferred Stock without par value.  The number of authorized shares of
any class of capital stock may be increased or decreased by the affirmative vote
of the holders of a majority of capital stock of the Corporation entitled to
vote.

The Board of Directors of the Corporation is granted full and complete authority
to fix by resolution or resolutions the designation, and the powers, preferences
and rights of the Preferred Stock and any series thereof, and the
qualifications, limitations or restrictions on such powers, preferences and
rights.

                    SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

    A series of Preferred Stock of the Corporation is hereby created and the
    designation, amount thereof and the working powers, preferences and
    relative, participating, optional and other special rights of the shares of
    such series, and the qualifications, limitations or restrictions thereof
    are as follows:

         Section 1.  DESIGNATION AND AMOUNT.  The shares of such series shall
    be designated as "Series A Junior Participating Preferred Stock" and the
    number of shares constituting such series shall be 1,000,000.

         Section. 2.  DIVIDENDS AND DISTRIBUTIONS.

         (A)  Subject to the prior and superior rights of the holders of any
    shares of any series

<PAGE>

    of Preferred Stock, if any, issued from time to time ranking prior and
    superior to the shares of Series A Junior Participating Preferred Stock
    with respect to dividends, the holders of shares of Series A Junior
    Participating Preferred Stock shall be entitled to receive, when, as and if
    declared by the Board of Directors out of funds legally available for the
    purpose, quarterly dividends payable in cash on the fifteenth day of
    February, May, August and November in each year (each such date being
    referred to herein as a "Quarterly Dividend Payment Date"), commencing on
    the first Quarterly Dividend Payment Date after the first issuance of a
    share or fraction of a share of Series A Junior Participating Preferred
    Stock, in an amount per share (rounded to the nearest cent) equal to the
    greater of (a) $1.00 or (b) subject to the provision for adjustment
    hereinafter set forth, 100 times the aggregate per share amount of all cash
    dividends, and 100 times the aggregate per share amount (payable in kind)
    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 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


                                          2

<PAGE>

    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 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


                                          3

<PAGE>

         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 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


                                          4

         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
         
              (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


                                          5

<PAGE>

         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 canceled 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.


                                          6

<PAGE>

         (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 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


                                          7

    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.

No stockholder shall have any preemptive right to subscribe to an additional
issue of capital stock or to any security convertible into such capital stock.

                                      ARTICLE IV

The business and affairs of the Corporation shall be managed by or under the
direction of a Board of Directors.  Except to the extent prohibited by law, the
Board of Directors shall have the right (which, to the extent exercised, shall
be exclusive) to establish the rights, powers, duties, rules and procedures (a)
that from time to time shall govern the Board of Directors and each of its
members including without limitation the vote required for any action by the
Board of Directors, and (b) that from time to time shall affect the directors'
power to manage and direct the business and affairs of the Corporation; and
Article V notwithstanding, no By-Law shall be adopted by the stockholders of the
Corporation which shall impair or impede the implementation of the foregoing.

The Board of Directors shall consist of a number of directors, which number
shall be determined from time to time exclusively by the Board of Directors
pursuant to a resolution adopted by affirmative vote of a majority of the entire
Board of Directors.  The directors shall be divided into three classes as nearly
equal in number as possible, designated Class I, Class II and Class III.  At the
1983 annual meeting of stockholders, Class I directors shall be elected for a
term expiring at the 1984 annual meeting of stockholders, Class II directors
shall be elected for a term expiring at the 1985 annual meeting of stockholders,
and Class III directors shall be elected for a term expiring at the 1986 annual
meeting of stockholders.  At each annual meeting of stockholders following such
initial classification and election, directors elected to succeed those
directors whose terms expire shall be elected for a term of office to expire at
the third succeeding annual meeting of stockholders after their election.

Notwithstanding the foregoing, whenever the holders of any one or more classes
or series of Preferred Stock shall have the right, voting separately by class or
series, to elect directors at an annual or special meeting of stockholders, the
election, term of office, filling of vacancies and other features of such
directorships shall be governed by the terms of the applicable designation of
the powers, preferences and rights made pursuant to Article III, and such
directors so elected shall not be divided into classes pursuant to this Article
IV unless expressly provided by such terms.

Subject to the rights of the holders of any class or series of the then
outstanding capital stock of the Corporation entitled to vote generally in the
election of directors, newly created directorships resulting from any increase
in the authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the directors
then in office, though less than a quorum, and directors so chosen shall hold
office for a term expiring at the annual meeting of stockholders at which the
term of office of the class to which they have been elected expires.  No
decrease in the number of authorized directors constituting the entire Board of
Directors shall shorten the term of any incumbent director.  Subject to the
rights of the holders of any class or series of the capital stock then 


                                          8

<PAGE>

outstanding, any director, or the entire Board of Directors, may be removed from
office at any time, but only for cause.

No director of the Corporation shall be personally liable to the Corporation or
its stockholders for monetary damages for breach of fiduciary duty by such
director as a director; provided, however, that this Article IV shall not
eliminate or limit the liability of a director to the extent provided by
applicable law (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the General Corporation Law of Delaware, or (iv) for any
transaction from which the director derived an improper personal benefit.  No
amendment to or repeal of this Article IV shall apply to, or have any effect on,
the liability or alleged liability of any director of the Corporation for or
with respect to any acts or omissions of such director occurring prior to such
amendment or repeal.

                                      ARTICLE V

The Board of Directors may from time to time, by vote of a majority of its
members, alter, amend or rescind all or any of the By-Laws of the Corporation,
as permitted by law, subject to the power of the stockholders to change or
repeal such By-Laws.

                                      ARTICLE VI

    A.  (1)  In addition to any affirmative vote required by law or the
Certificate of Incorporation or By-Laws of the Corporation, and except as
otherwise expressly provided in paragraph B of this Article VI

              (a)  any merger or consolidation of the Corporation or any
         Subsidiary (as hereinafter defined) with (i) any Interested
         Stockholder (as hereinafter defined) or (ii) any other corporation
         (whether or not itself an Interested Stockholder) which is, or after
         such merger or consolidation would be, an Affiliate (as hereinafter
         defined) of an Interested Stockholder; or

              (b)  any sale, lease, exchange, mortgage, pledge, transfer or
         other disposition (in one transaction or a series of transactions) to
         or with any Interested Stockholder or any Affiliate of any Interested
         Stockholder involving any assets or securities of the Corporation, any
         Subsidiary or any Interested Stockholder or any Affiliate of any
         Interested Stockholder, having  an aggregate Fair Market Value (as
         hereinafter defined) of $10,000,000 or more; or

              (c)  the adoption of any plan or proposal for the liquidation or
         dissolution of the Corporation proposed by or on behalf of an
         Interested Stockholder or any Affiliate of any Interested Stockholder;
         or

              (d)  any reclassification of securities (including any reverse
         stock split), or recapitalization of the Corporation, or any merger or
         consolidation of the Corporation with any of its Subsidiaries or any
         other transaction (whether or not with or otherwise involving an
         Interested Stockholder) which has the effect, directly or indirectly,
         of increasing the proportionate share of any class of equity or
         convertible securities of the Corporation or any Subsidiary which is
         directly or indirectly beneficially owned


                                          9

<PAGE>

         by any Interested Stockholder or any Affiliate of any Interested
         Stockholder; or 
 
              (e)  any agreement, contract or other arrangement providing for
         any one or more of the actions specified in clauses (a) to (d) of this
         subparagraph (1), shall require the affirmative vote of at least
         eighty percent (80%) of the voting power of all of the then
         outstanding shares of the Voting Stock (as hereinafter defined) voting
         together as a single class (it being understood that, for purposes of
         this Article VI, each share of the Preference Stock (as hereinafter
         defined) which is Voting Stock shall have the number of votes granted
         to it pursuant to the applicable Preferred Stock Designation (as
         hereinafter defined) or Article III of this Certificate of
         Incorporation).  Such affirmative vote shall be required
         notwithstanding the fact that no vote may be required, or that a
         lesser percentage may be specified, by law or in any agreement with
         any national securities exchange or otherwise.

         (2)  The term "Business Combination" as used in this Article VI shall
    mean any transaction  which is referred to in any one or more of clauses
    (a) through (e) of subparagraph (1) of paragraph A.

    B.  The provisions of paragraph A of this Article VI shall not be
applicable to any particular Business Combination, and such Business Combination
shall require only such affirmative vote, if any, as is required by law and any
other provision of the Certificate of Incorporation or the By-Laws of the
Corporation, if all of the conditions specified in either of the following
subparagraphs (1) or (2) are met:

         (1)  The Business Combination shall have been approved (whether such
    approval is made prior to or subsequent to the acquisition of beneficial
    ownership of the Voting Stock which caused the Interested Stockholder to
    become an Interested Stockholder) by a majority of the Continuing Directors
    (as hereinafter defined).

         (2)  All of the following conditions shall have been met:

              (a)  The consideration to be received by holders of a particular
         class of outstanding Voting Stock shall be in cash or in the same form
         as previously paid by or on behalf of the Interested Stockholder in
         connection with its direct or indirect acquisition of beneficial
         ownership of shares of such class of Voting Stock.  If the
         consideration so paid for shares of any class of Voting Stock varied
         as to form, the form of consideration for such class of Voting Stock
         shall be either cash or the form used to acquire beneficial ownership
         of the largest number of shares of such class of  Voting Stock
         previously acquired by the Interested Stockholder.

              (b)  The aggregate amount of (x) cash and (y) the Fair Market
         Value as of the date of the consummation of the Business Combination
         of consideration other than cash to be received per share by holders
         of Common Stock in such Business Combination shall be at least equal
         to the higher amount determined under subclauses (i) and (ii) below:

                   (i)  (if applicable) the highest per share price (including
              any brokerage commissions, transfer taxes and soliciting dealers'
              fees) paid by or on behalf of the Interested Stockholder for any
              share of Common Stock in connection


                                          10

<PAGE>

              with the acquisition by the Interested Stockholder of beneficial
              ownership of such share (x) within the two-year period
              immediately prior to the first public announcement of the
              proposal of the Business Combination (the "Announcement Date") or
              (y) in the transaction in which the Interested Stockholder became
              an Interested Stockholder, whichever is higher; and

                   (ii)  the Fair Market Value per share of Common Stock on the
              Announcement Date or on the date on which the Interested
              Stockholder became an Interested Stockholder (such latter date is
              referred to in this Article VI as the "Determination Date"),
              whichever is higher.

              (c)  The aggregate amount of (x) cash and (y) the Fair Market
         Value as of the date of the consummation of the Business Combination
         of consideration other than cash to be received per share by holders
         of shares of any class of outstanding Preference Stock, shall be at
         least equal to the highest amount determined under subclauses (i),
         (ii) and (iii) below:

                   (i)  (if applicable) the highest per share price (including
              any brokerage commissions, transfer taxes and soliciting dealers'
              fees) paid by or on behalf of the Interested Stockholder for any
              share of such class of Preference Stock in connection with the
              acquisition by the Interested Stockholder of beneficial ownership
              of such share (x) within the two-year period immediately prior to
              the Announcement Date or (y) in the transaction in which the
              Interested Stockholder became an Interested Stockholder,
              whichever is higher; 

                   (ii)  the Fair Market Value per share of such class of
              Preference Stock on the Announcement Date or on the Determination
              Date, whichever is higher; and

                   (iii)  the highest preferential amount per share to which
              the holders of shares of such class of Preference Stock would be
              entitled in the event of any voluntary or involuntary
              liquidation, dissolution or winding up of the affairs of the
              Corporation, regardless of whether the Business Combination to be
              consummated constitutes such an event.

              The provisions of this subparagraph (2) (c) shall be required to
              be met with respect to every class of outstanding Preference
              Stock, whether or not the Interested Stockholder has previously
              acquired beneficial ownership of any shares of a particular class
              of Preference Stock.

              (d)  After such Interested Stockholder has become an Interested
         Stockholder and prior to the consummation of such Business
         Combination:  (i) there shall have been no failure to declare and pay
         at the regular date therefor any full dividends (whether or not
         cumulative) on the outstanding Preference Stock, except as approved by
         a majority of the Continuing Directors; (ii) there shall have been (x)
         no reduction in the annual rate of dividends paid on the Common Stock
         (except as necessary to reflect any subdivision of the Common Stock),
         except as approved by a majority of the Continuing Directors, and (y)
         an increase in such annual rate of dividends as necessary to reflect
         any reclassification (including any reverse stock split),


                                          11

<PAGE>

         recapitalization, reorganization or any similar transaction which has
         the effect of reducing the number of outstanding shares of Common
         Stock unless the failure so to increase such annual rate is approved
         by a majority of the Continuing Directors;  and (iii) such Interested
         Stockholder shall not have become the beneficial owner of any
         additional shares of Voting Stock except as part of the transaction
         which results in such Interested Stockholder becoming an Interested
         Stockholder and except in a transaction which, after giving effect
         thereto, would not result in any increase in the Interested
         Stockholder's percentage beneficial ownership of any class of Voting
         Stock.

              (e)  After becoming an Interested Stockholder, such Interested
         Stockholder shall not have received the benefit, directly or
         indirectly (except proportionately as a stockholder of the
         Corporation), of any loans, advances, guarantees, pledges or other

    successor of a Continuing Director, while such successor is a member of the
    Board, who is unaffiliated with the Interested Stockholder and is
    recommended or elected to succeed a Continuing Director by a majority of
    Continuing Directors.

         (8)  The term "Fair Market Value" means (a) in the case of stock, the

<PAGE>

    day period preceding the date in question on the NASD Automated Quotations
    System or any system then in use, or if no such quotations are available,

    determined by a majority of the Continuing Directors in good faith; and (b)
    in the case of property other than cash or stock, the fair market value of

    generally in the election of directors.

         (12)  In the event of any Business Combination in which the

    received" as used in subparagraphs (2)(b) and (c) of paragraph B of Article
    VI shall include the shares of Common Stock and/or the shares of any other
    class of Voting Stock retained by the holders of such shares.

    D.  Nothing contained in this Article VI shall be construed to relieve any
Interested Stockholder from any fiduciary obligation imposed by law.

    E.  The fact that any Business Combination complies with the provisions of
paragraph B of this Article VI shall not be construed to impose any fiduciary
duty, obligation or responsibility on the Board of Directors, or any member
thereof, to approve such Business Combination or recommend its adoption or
approval to the stockholders of the Corporation, nor shall such compliance
limit, prohibit or otherwise restrict in any manner the Board of Directors, or
any member thereof, with respect to evaluations of or actions and responses
taken with respect to such Business Combination.

    F.  Notwithstanding any other provisions of the Certificate of
Incorporation of the Corporation or any provision of law which might otherwise
permit a lesser vote or no vote, but in addition to any affirmative vote of the
holders of any particular class or series of Voting Stock required by law, the
Certificate of Incorporation of the Corporation or any Preferred Stock
Designation, the affirmative vote of the holders of at least eighty percent
(80%) of the voting power of all of the then outstanding shares of Voting Stock,
voting together as a single class, shall be required to amend or repeal this
Article VI, or adopt any provisions inconsistent with this Article VI; provided
that, this paragraph F shall not apply to, and such eighty percent (80%) vote
shall not be required for, any amendment, repeal or adoption unanimously
recommended by the Board of Directors of the Corporation if all of such
directors are persons who would be eligible to serve as Continuing Directors.

securities registered under Section 12 of the Exchange Act, any committee
administering the Plan will consist solely of two or more members of the Board
who are "non-employee directors" within the meaning of Rule 16b-3 under the

"outside directors" within the meaning of Section 162(m) of the Code.  Such a
committee, if established, will act by majority approval of the members
(unanimous approval with respect to action by written consent), and a majority
of the members of such a committee will constitute a quorum.  As used in the
Plan, "Committee" will refer to the Board or to such a committee, if
established.  To the extent consistent with corporate law, the Committee may
delegate to any officers of the Company the duties, power and authority of the
Committee under the Plan pursuant to such conditions or limitations as the
Committee may establish; provided, however, that only the Committee may exercise
such duties, power and authority with respect to Eligible Recipients who are
subject to Section 16 of the Exchange Act.  The Committee may exercise its
duties, power and authority under the Plan in its sole and absolute discretion
without the consent of any Participant or other party, unless the Plan
specifically provides otherwise.  Each determination, interpretation or other
action made or taken by the Committee pursuant to the provisions of the Plan
will be conclusive and binding for all purposes and on all persons, and no
member of the Committee will be liable for any action or determination made in
good faith with respect to the Plan or any Incentive Award granted under the
Plan. 


                                          3

<PAGE>

    3.2  AUTHORITY OF THE COMMITTEE.

         (a)  In accordance with and subject to the provisions of the Plan, the
    Committee will have the authority to determine all provisions of Incentive
    Awards as the Committee may deem necessary or desirable and as consistent
    with the terms of the Plan, including, without limitation, the following:
    (i) the Eligible Recipients to be selected as Participants; (ii) the nature
    and extent of the Incentive Awards to be made to each Participant
    (including the number of shares of Common Stock to be subject to each
    Incentive Award, any exercise price, the manner in which Incentive Awards
    will vest or become exercisable and whether Incentive Awards will be
    granted in tandem with other Incentive Awards) and the form of written
    agreement, if any, evidencing such Incentive Award; (iii) the time or times
    when Incentive Awards will be granted; (iv) the duration of each Incentive
    Award; and (v) the restrictions and other conditions to which the payment
    or vesting of Incentive Awards may be subject.  In addition, the Committee
    will have the authority under the Plan in its sole discretion to pay the
    economic value of any Incentive Award in the form of cash, Common Stock or
    any combination of both.

         (b)  The Committee will have the authority under the Plan to amend or
    modify the terms of any outstanding Incentive Award in any manner,
    including, without limitation, the authority to modify the number of shares
    or other terms and conditions of an Incentive Award, extend the term of an
    Incentive Award, accelerate the exercisability or vesting or otherwise
    terminate any restrictions relating to an Incentive Award, accept the
    surrender of any outstanding Incentive Award or, to the extent not
    previously exercised or vested, authorize the grant of new Incentive Awards
    in substitution for surrendered Incentive Awards; provided, however that
    the amended or modified terms are permitted by the Plan as then in effect,
    that no amendment or modification of an outstanding Incentive Award (other
    than as may be required pursuant to Section 4.3 of the Plan) may decrease
    the per share exercise price of an Option below the Fair Market Value of
    the Common Stock on the date of grant, and that any Participant adversely
    affected by such amended or modified terms has consented to such amendment
    or modification.  No amendment or modification to an Incentive Award,
    however, whether pursuant to this Section 3.2 or any other provisions of
    the Plan, will be deemed to be a regrant of such Incentive Award for
    purposes of this Plan.

         (c)  In the event of (i) any reorganization, merger, consolidation,
    recapitalization, liquidation, reclassification, stock dividend, stock
    split, combination of shares, rights offering, extraordinary dividend or
    divestiture (including a spin-off) or any other change in corporate
    structure or shares, (ii) any purchase, acquisition, sale or disposition of
    a significant amount of assets or a significant business, (iii) any change
    in accounting principles or practices, or (iv) any other similar change, in
    each case with respect to the Company or any other entity whose performance
    is relevant to the grant or vesting of an Incentive Award, the Committee
    (or, if the Company is not the surviving corporation in any such
    transaction, the board of directors of the surviving corporation) may,
    without the consent of any affected Participant, amend or modify the
    vesting criteria of any outstanding Incentive Award that is based in whole
    or in part on the financial performance of the Company (or any Subsidiary
    or division or other subunit thereof) or such other entity so as equitably
    to reflect such event, with the desired result that the criteria for


                                          4

<PAGE>

    evaluating such financial performance of the Company or such other entity
    will be substantially the same (in the sole discretion of the Committee or
    the board of directors of the surviving corporation) following such event
    as prior to such event; provided, however, that the amended or modified
    terms are permitted by the Plan as then in effect.

4.  SHARES AVAILABLE FOR ISSUANCE.

    4.1  MAXIMUM NUMBER OF SHARES AVAILABLE.  Subject to adjustment as provided
in Section 4.3 of the Plan, the maximum number of shares of Common Stock that
will be available for issuance under the Plan will be 3,000,000 shares of Common
Stock.  Notwithstanding any other provisions of the Plan to the contrary, no
Participant in the Plan may be granted any Options or any other Incentive Awards
with a value based solely on an increase in the value of the Common Stock after
the date of grant, relating to more than 800,000 shares of Common Stock in the
aggregate during any 48- month period (subject to adjustment as provided in
Section 4.3 of the Plan).  The shares available for issuance under the Plan may,
at the election of the Committee, be either treasury shares or shares authorized
but unissued, and, if treasury shares are used, all references in the Plan to
the issuance of shares will, for corporate law purposes, be deemed to mean the
transfer of shares from treasury.

    4.2  ACCOUNTING FOR INCENTIVE AWARDS.  Shares of Common Stock that are
issued under the Plan or that are subject to outstanding Incentive Awards will
be applied to reduce the maximum number of shares of Common Stock remaining
available for issuance under the Plan.  Any shares of Common Stock that are
subject to an Incentive Award that lapses, expires, is forfeited or for any
reason is terminated unexercised or unvested and any shares of Common Stock that
are subject to an Incentive Award that is settled or paid in cash or any form
other than shares of Common Stock will automatically again become available for
issuance under the Plan.  Any shares of Common Stock that constitute the
forfeited portion of a Restricted Stock Award, however, will not become
available for further issuance under the Plan.

    4.3  ADJUSTMENTS TO SHARES AND INCENTIVE AWARDS.  In the event of any
reorganization, merger, consolidation, recapitalization, liquidation,
reclassification, stock dividend, stock split, combination of shares, rights
offering, divestiture or extraordinary dividend (including a spin-off) or any
other change in the corporate structure or shares of the Company, the Committee
(or, if the Company is not the surviving corporation in any such transaction,
the board of directors of the surviving corporation) will make appropriate
adjustment (which determination will be conclusive) as to the number and kind of
securities or other property (including cash) available for issuance or payment
under the Plan and, in order to prevent dilution or enlargement of the rights of
Participants, (a) the number and kind of securities or other property (including
cash) subject to outstanding Incentive Awards, and (b) the exercise price of
outstanding Options.

5.  PARTICIPATION.  

    Participants in the Plan will be those Eligible Recipients who, in the
judgment of the Committee, have contributed, are contributing or are expected to
contribute to the achievement of economic objectives of the Company or its
Subsidiaries.  Eligible Recipients may be granted from time to time one or more


                                          5

<PAGE>

Incentive Awards, singly or in combination or in tandem with other Incentive
Awards, as may be determined by the Committee in its sole discretion.  Incentive
Awards will be deemed to be granted as of the date specified in the grant
resolution of the Committee, which date will be the date of any related
agreement with the Participant.

6.  OPTIONS.

    6.1  GRANT.  An Eligible Recipient may be granted one or more Options under
the Plan, and such Options will be subject to such terms and conditions,
consistent with the other provisions of the Plan, as may be determined by the
Committee in its sole discretion.  The Committee may designate whether an Option
is to be considered an Incentive Stock Option or a Non-Statutory Stock Option. 
To the extent that any Incentive Stock Option granted under the Plan ceases for
any reason to qualify as an "incentive stock option" for purposes of Section 422
of the Code, such Incentive Stock Option will continue to be outstanding for
purposes of the Plan but will thereafter be deemed to be a Non-Statutory Stock
Option.

    6.2  EXERCISE PRICE.  The per share price to be paid by a Participant upon
exercise of an Option will be determined by the Committee in its discretion at
the time of the Option grant, provided that such price will not be less than
100% of the Fair Market Value of one share of Common Stock on the date of grant.

    6.3  EXERCISABILITY AND DURATION.  An Option will become exercisable at
such times and in such installments as may be determined by the Committee in its
sole discretion at the time of grant; provided, however, that no Option may be
exercisable prior to six months (other than as provided in Section 9.1 of the
Plan) or after 10 years from its date of grant. 

    6.4  PAYMENT OF EXERCISE PRICE.  The total purchase price of the shares to
be purchased upon exercise of an Option will be paid entirely in cash (including
check, bank draft or money order); provided, however, that the Committee, in its
sole discretion and upon terms and conditions established by the Committee, may
allow such payments to be made, in whole or in part, by tender of a Broker
Exercise Notice, Previously Acquired Shares or by a combination of such methods.

    6.5  MANNER OF EXERCISE.  An Option may be exercised by a Participant in
whole or in part from time to time, subject to the conditions contained in the
Plan and in the agreement evidencing such Option, by delivery in person, by
facsimile or electronic transmission or through the mail of written notice of
exercise to the Company at its principal executive office in St. Paul, Minnesota
and by paying in full the total exercise price for the shares of Common Stock to
be purchased in accordance with Section 6.4 of the Plan.

7.  RESTRICTED STOCK AWARDS.

    7.1  GRANT.  An Eligible Recipient may be granted one or more Restricted
Stock Awards under the Plan, and such Restricted Stock Awards will be subject to
such terms and conditions, consistent with


                                          6

<PAGE>

the other provisions of the Plan, as may be determined by the Committee in its
sole discretion.  The Committee may impose such restrictions or conditions, not
inconsistent with the provisions of the Plan, to the vesting of such Restricted
Stock Awards as it deems appropriate, including, without limitation, that the
Participant remain in the continuous employ or service of the Company or a
Subsidiary for a certain period or that the Participant or the Company (or any
Subsidiary or division or other subunit thereof) satisfy certain performance
goals or criteria; provided, however, that other than as provided in Section 9.1
of the Plan, no Restricted Stock Award may vest prior to six months from its
date of grant.

    7.2  RIGHTS AS A STOCKHOLDER; TRANSFERABILITY.  Except as provided in
Sections 7.1, 7.3 and 12.3 of the Plan, a Participant will have all voting,
dividend, liquidation and other rights with respect to shares of Common Stock
issued to the Participant as a Restricted Stock Award under this Section 7 upon
the Participant becoming the holder of record of such shares as if such
Participant were a holder of record of shares of unrestricted Common Stock.

    7.3  DIVIDENDS AND DISTRIBUTIONS.  Unless the Committee determines
otherwise in its sole discretion (either in the agreement evidencing the
Restricted Stock Award at the time of grant or at any time after the grant of
the Restricted Stock Award), any dividends or distributions (other than regular
quarterly cash dividends) paid with respect to shares of Common Stock subject to
the unvested portion of a Restricted Stock Award will be subject to the same
restrictions as the shares to which such dividends or distributions relate.  The
Committee will determine in its sole discretion whether any interest will be
paid on such dividends or distributions.  The Committee, in an agreement
evidencing a Restricted Stock Award, may require that, unless the Participant
elects otherwise, regular quarterly cash dividends paid with respect to shares
of Common Stock subject to a portion of the Restricted Stock Award that has not
vested will be reinvested (and in such case Participants hereby consent to such
reinvestment) in shares of Common Stock pursuant and in accordance with the
Company's regular dividend reinvestment plan.

    7.4  ENFORCEMENT OF RESTRICTIONS.  To enforce the restrictions referred to
in this Section 7, the Committee may place a legend on the stock certificates
referring to such restrictions and may require the Participant, until the
restrictions have lapsed, to keep the stock certificates, together with duly
endorsed stock powers, in the custody of the Company or its transfer agent, or
to maintain evidence of stock ownership, together with duly endorsed stock
powers, in a certificateless book-entry stock account with the Company's
transfer agent.

8.  PERFORMANCE STOCK AWARDS.

    An Eligible Recipient may be granted one or more Performance Stock Awards
under the Plan, and such Performance Stock Awards will be subject to such terms
and conditions, if any, consistent with the other provisions of the Plan, as may
be determined by the Committee in its sole discretion.  The Participant will
have all voting, dividend, liquidation and other rights with respect to the
shares of Common Stock issued to a Participant as a Performance Stock Award
under this Section 8 upon the Participant becoming the holder of record of such
shares; provided, however, that the Committee may impose such restrictions on
the assignment or transfer of a Performance Stock Award as it deems appropriate,
and may enforce such restrictions by any or all of the methods set forth in
Section 7.4 of the


                                          7

<PAGE>

Plan.

9.  EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE.

    9.1  TERMINATION OF EMPLOYMENT DUE TO DEATH OR DISABILITY.  In the event a
Participant's employment with the Company and all Subsidiaries is terminated by
reason of death or Disability:

         (a)  All outstanding Options then held by the Participant will become
    immediately exercisable in full and will remain exercisable for a period of
    five years after such termination (but in no event after the expiration
    date of any such Option);

         (b)  All Restricted Stock Awards then held by the Participant will
    become fully vested; and

         (c)  Any assignment or transfer restrictions with respect to
    Performance Stock Awards will lapse.

    9.2  Termination of Employment Due to Retirement.  In the event a
Participant's employment with the Company and all Subsidiaries is terminated by
reason of Retirement:

         (a)  All outstanding Options then held by the Participant will remain
    exercisable in full and will remain exercisable to the extent exercisable
    as of such termination for a period of five years after such termination
    (but in no event after the expiration date of any such Option);

         (b)  All Restricted Stock Awards then held by the Participant that
    have not vested as of such termination will be terminated and forfeited;
    and

         (c)  Any assignment or transfer restrictions with respect to
    Performance Stock Awards that have not lapsed will continue in effect in
    accordance with their terms unless otherwise provided in the agreement
    evidencing such Performance Stock Awards.

    9.3  TERMINATION OF EMPLOYMENT FOR REASONS OTHER THAN DEATH, DISABILITY OR
         RETIREMENT.  

         (a)  In the event a Participant's employment is terminated with the
    Company and all Subsidiaries for any reason other than death, Disability or
    Retirement, or a Participant is in the employ of a Subsidiary and the
    Subsidiary ceases to be a Subsidiary of the Company (unless the Participant
    continues in the employ of the Company or another Subsidiary), all rights
    of the Participant under the Plan and any agreements evidencing an
    Incentive Award will immediately terminate without notice of any kind, and
    (i) no Options then held by the Participant will thereafter be exercisable,
    (ii) all Restricted Stock Awards then held by the Participant that have not
    vested will be terminated and forfeited, and (iii) any assignment or
    transfer restrictions with


                                          8

<PAGE>

    respect to Performance Stock Awards that have not lapsed will continue in
    effect in accordance with their terms unless otherwise provided in the
    agreement evidencing such Performance Stock Awards; provided, however, that
    if such termination is due to any reason other than termination by the
    Company or any Subsidiary for "cause," all outstanding Options then held by
    such Participant will remain exercisable to the extent exercisable as of
    such termination for a period of three months after such termination (but
    in no event after the expiration date of any such Option).

         (b)  For purposes of this Section 9, "cause" (as determined by the
    Committee) will be as defined in any employment or other agreement or
    policy applicable to the Participant or, if no such agreement or policy
    exists, will mean (i) dishonesty, fraud, misrepresentation, embezzlement or
    deliberate injury or attempted injury, in each case related to the Company
    or any Subsidiary, (ii) any unlawful or criminal activity of a serious
    nature, (iii) any intentional and deliberate breach of a duty or duties
    that, individually or in the aggregate, are material in relation to the
    Participant's overall duties, or (iv) any material breach of any
    employment, service, confidentiality or noncompete agreement entered into
    with the Company or any Subsidiary.

    9.4  TERMINATION OF SERVICE AS A NON-EMPLOYEE CONSULTANT OR ADVISOR.  In
the event a Participant's service as a non-employee consultant or advisor is
terminated with the Company and all Subsidiaries for any reason, or a
Participant is in the service of a Subsidiary and the Subsidiary ceases to be a
Subsidiary of the Company (unless the Participant continues in the service of
the Company or another Subsidiary), all rights of the Participant under the Plan
and any agreements evidencing an Incentive Award will immediately terminate
without notice of any kind, and (i) no Options then held by the Participant will
thereafter be exercisable, (ii) all Restricted Stock Awards then held by the
Participant that have not vested will be terminated and forfeited, and (iii) any
assignment or transfer restrictions with respect to Performance Stock Awards
that have not lapsed will continue in effect in accordance with their terms
unless otherwise provided in the agreement evidencing such Performance Stock
Awards; provided, however, that if such termination is due to any reason other
than termination by the Company or any Subsidiary for "cause" (as defined in
Section 9.3(b) of the Plan), all outstanding Options then held by such
Participant will remain exercisable to the extent exercisable as of such
termination for a period of three months after such termination (but in no event
after the expiration date of any such Option).

    9.5  MODIFICATION OF RIGHTS UPON TERMINATION.  Notwithstanding the other
provisions of this Section 9, upon a Participant's termination of employment or
other service with the Company and all Subsidiaries, the Committee may, in its
sole discretion (which may be exercised at any time on or after the date of
grant, including following such termination), cause Options (or any part
thereof) then held by such Participant to become or continue to become
exercisable and/or remain exercisable following such termination of employment
or other service, and Restricted Stock Awards and Performance Stock Awards then
held by such Participant to vest and/or continue to vest or become free of
transfer restrictions, as the case may be, following such termination of
employment or other service, in each case in the manner determined by the
Committee; provided, however, that (a) no Incentive Award will become
exercisable or vest prior to six months from its date of grant (unless such
exercisability or vesting is by reason of death or Disability), and (b) no
Incentive Award may remain exercisable or continue to vest for more than two
years beyond the date such Incentive Award would have terminated if not for the
provisions of this


                                          9

<PAGE>

Section 9.5 but in no event beyond its expiration date.

    9.6  BREACH OF CONFIDENTIALITY OR NONCOMPETE AGREEMENTS.  Notwithstanding
anything in the Plan to the contrary, in the event that a Participant materially
breaches the terms of any confidentiality or noncompete agreement entered into
with the Company or any Subsidiary, whether such breach occurs before or after
termination of such Participant's employment or Other Service with the Company
or any Subsidiary, the Committee in its sole discretion may immediately
terminate all rights of the Participant under the Plan and any agreements
evidencing an Incentive Award then held by the Participant without notice of any
kind.

    9.7  DETERMINATION OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE.

         (a)  The change in a Participant's status from that of an employee of
    the Company or any Subsidiary to that of a non-employee consultant or
    advisor of the Company or any Subsidiary will, for purposes of the Plan, be
    deemed to result in a termination of such Participant's employment with the
    Company and its Subsidiaries, unless the Committee otherwise determines in
    its sole discretion.  

         (b)  The change in a Participant's status from that of a non-employee
    consultant or  advisor of the Company or any Subsidiary to that of an
    employee of the Company or any Subsidiary will not, for purposes of the
    Plan, be deemed to result in a termination of such Participant's service as
    a non-employee consultant or advisor with the Company and its Subsidiaries,
    and such Participant will thereafter be deemed to be an employee of the
    Company or its Subsidiaries until such Participant's employment is
    terminated, in which event such Participant will be governed by the
    provisions of this Plan relating to termination of employment.

         (c)  Unless the Committee otherwise determines in its sole discretion,
    a Participant's employment or other service will, for purposes of the Plan,
    be deemed to have terminated on the date recorded on the personnel or other
    records of the Company or the Subsidiary for which the Participant provides
    employment, as determined by the Committee in its sole discretion based
    upon such records.

10. PAYMENT OF WITHHOLDING TAXES.

    10.1  GENERAL RULES.  The Company is entitled to (a) withhold and deduct
from future wages of the Participant (or from other amounts that may be due and
owing to the Participant from the Company or a Subsidiary), or make other
arrangements for the collection of, all legally required amounts necessary to
satisfy any and all federal, state and local withholding and employment-related
tax requirements attributable to an Incentive Award, including, without
limitation, the grant, exercise or vesting of, or payment of dividends with
respect to, an Incentive Award or a disqualifying disposition of stock received
upon exercise of an Incentive Stock Option, or (b) require the Participant
promptly to remit the amount of such withholding to the Company before taking
any action, including issuing any shares of Common


                                          10

<PAGE>

Stock, with respect to an Incentive Award.

    10.2  SPECIAL RULES.  The Committee may, in its sole discretion and upon
terms and conditions established by the Committee, permit or require a
Participant to satisfy, in whole or in part, any withholding or
employment-related tax obligation described in Section 10.1 of the Plan by
electing to tender Previously Acquired Shares, a Broker Exercise Notice or a
combination of such methods.  

11. CHANGE IN CONTROL.

    11.1  CHANGE IN CONTROL.  For purposes of this Section 11, a "Change in
Control" of the Company will mean the following:

         (a)  Any "person" as such term is used in Sections 13(d) and 14(d) of
    the Exchange Act (other than the Company, any trustee or other fiduciary
    holding securities under any employee benefit plan of the Company, or any
    corporation owned, directly or indirectly, by the stockholders of the
    Company in substantially the same proportions as their ownership of stock
    of the Company), is or becomes, including pursuant to a tender or exchange
    offer for shares of Common Stock pursuant to which purchases are made, the
    "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act),
    directly or indirectly, of securities of the Company representing 25% or
    more of the combined voting power of the Company's then outstanding
    securities, other than in a transaction arranged or approved by the Board
    prior to its occurrence; provided, however, that if any such person will
    become the beneficial owner, directly or indirectly, of securities of the
    Company representing 34% or more of the combined voting power of the
    Company's then outstanding securities, a Change in Control will be deemed
    to occur whether or not any or all of such beneficial ownership is obtained
    in a transaction arranged or approved by the Board prior to its occurrence,
    and other than in a transaction in which such person will have executed a
    written agreement with the Company (and approved by the Board) on or prior
    to the date on which such person becomes the beneficial owner of 25% or
    more of the combined voting power of the Company's then outstanding
    securities, which agreement imposes one or more limitations on the amount
    of such person's beneficial ownership of shares of Common Stock, if, and so
    long as, such agreement (or any amendment thereto approved by the Board
    provided that no such amendment will cure any prior breach of such
    agreement or any amendment thereto) continues to be binding on such person
    and such person is in compliance (as determined by the Board in its sole
    discretion) with the terms of such agreement (including such amendment);
    provided, however, that if any such person will become the beneficial
    owner, directly or indirectly, of securities of the Company representing
    50% or more of the combined voting power of the Company's then outstanding
    securities, a Change in Control will be deemed to occur whether or not such
    beneficial ownership was held in compliance with such a binding agreement.

         (b)  During any period of two consecutive years, individuals who at
    the beginning of such period constitute the Board, and any new director
    (other than a director designated by a person who has entered into an
    agreement with the Company to effect a transaction which would constitute a
    Change in Control pursuant to this Section 11.1) whose election by the
    Board or


                                          11

<PAGE>

    nomination for election by the Company's stockholders was approved by a
    vote of at least two-thirds of the directors then still in office who
    either were directors at the beginning of the period or whose election or
    nomination for election was previously so approved, cease for any reason to
    constitute at least a majority thereof.

         (c)  The stockholders of the Company approve a merger or consolidation
    of the Company with any other corporation, other than (i) a merger or
    consolidation which would result in the voting securities of the Company
    outstanding immediately prior thereto continuing to represent (either by
    remaining outstanding or by being converted into voting securities of the
    surviving entity) more than 80% of the combined voting power of the voting
    securities of the Company or such surviving entity outstanding immediately
    after such merger or consolidation, or (ii) a merger or consolidation
    effected to implement a recapitalization of the Company (or similar
    transaction) in which no person acquires a percentage of the combined
    voting power of the Company's then outstanding securities which would
    constitute a Change in Control pursuant to Section 11.1 above.  In case of
    any consolidation or merger of another corporation into the Company in
    which the Company is the surviving corporation and in which there is a
    reclassification or change (including a change to the right to receive cash
    or other property) of the shares of Common Stock (other than a change in
    par value, or from par value to no par value, or as a result of a
    subdivision or combination, but including any change in such shares into
    two or more classes or series of shares), Section 4.3 of the Plan will
    apply.

         (d)  The stockholders of the Company approve a plan of complete
    liquidation of the Company or an agreement for the sale or disposition by
    the Company of all or substantially all of the Company's assets.

    11.2  ACCELERATION OF VESTING.  Without limiting the authority of the
Committee under Sections 3.2 and 4.3 of the Plan, if a Change in Control of the
Company occurs, then, if approved by the Committee in its sole discretion either
in an agreement evidencing an Incentive Award at the time of grant or at any
time after the grant of an Incentive Award, (a) all Options that have been
outstanding for at least six months will become immediately exercisable in full
and will remain exercisable in accordance with their terms; (b) all outstanding
Restricted Stock Awards that have been outstanding for at least six months will
become immediately fully vested and non-forfeitable; and (c) any transfer
restrictions with respect to Performance Stock Awards will lapse.

    11.3  CASH PAYMENT FOR OPTIONS.  If a Change in Control of the Company
occurs, then the Committee, if approved by the Committee in its sole discretion
either in an agreement evidencing an Incentive Award at the time of grant or at
any time after the grant of an Incentive Award, and without the consent of any
Participant affected thereby, may determine that some or all Participants
holding outstanding Options will receive, with respect to some or all of the
shares of Common Stock subject to such Options, as of the effective date of any
such Change in Control of the Company, cash in an amount equal to the excess of
the Fair Market Value of such shares immediately prior to the effective date of
such Change in Control of the Company over the exercise price per share of such
Options.


                                          12

<PAGE>

    11.4  LIMITATION ON CHANGE IN CONTROL PAYMENTS.  Notwithstanding anything
in Section 11.2 or 11.3 of the Plan to the contrary, if, with respect to a
Participant, any of the payments to be made in connection with Section 11.2 or
11.3 of the Plan, together with any other payments or benefits which a
Participant has the right to receive from the Company or any corporation which
is a member of an "affiliated group" (as defined in section 1504(a) of the Code
without regard to section 1504(b) of the Code) of which the Company is a member,
constitute an "excess parachute payment" (as defined in section 280G(b) of the
Code), the payments to be made in connection with Section 11.2 or 11.3 of the
Plan shall be reduced to the extent necessary to prevent any portion of such
payments or benefits from becoming subject to the excise tax imposed under
section 4999 of the Code;  provided, however, that if a Participant is subject
to a separate agreement with the Company or a Subsidiary that expressly
addresses the potential application of Sections 280G or 4999 of the Code
(including, without limitation, that "payments" under such agreement or
otherwise will be reduced, that such payments will not be reduced or that the
Participant will have the discretion to determine which "payments" will be
reduced), then this Section 11.4 will not apply, and any "payments" to a
Participant pursuant to Section 11.2 or 11.3 of the Plan will be treated as
"payments" arising under such separate agreement.

12. RIGHTS OF ELIGIBLE RECIPIENTS AND PARTICIPANTS; TRANSFERABILITY.

    12.1  EMPLOYMENT OR OTHER SERVICE.  Nothing in the Plan will interfere with
or limit in any way the right of the Company or any Subsidiary to terminate the
employment or Other Service of any Eligible Recipient or Participant at any
time, nor confer upon any Eligible Recipient or Participant any right to
continue in the employ or Other Service of the Company or any Subsidiary.

    12.2  RIGHTS AS A STOCKHOLDER.  As a holder of Incentive Awards (other than
Restricted Stock Awards and Performance Stock Awards), a Participant will have
no rights as a stockholder unless and until such Incentive Awards are exercised
for, or paid in the form of, shares of Common Stock and the Participant becomes
the holder of record of such shares.  Except as otherwise provided in the Plan,
no adjustment will be made for dividends or distributions with respect to such
Incentive Awards as to which there is a record date preceding the date the
Participant becomes the holder of record of such shares, except as the Committee
may determine in its discretion.

    12.3  RESTRICTIONS ON TRANSFER.  Except pursuant to testamentary will or
the laws of descent and distribution or as otherwise expressly permitted by the
Plan, no right or interest of any Participant in an Incentive Award prior to the
exercise or vesting of such Incentive Award will be assignable or transferable,
or subjected to any lien, during the lifetime of the Participant, either
voluntarily or involuntarily, directly or indirectly, by operation of law or
otherwise.  A Participant will, however, be entitled to designate a beneficiary
to receive an Incentive Award upon such Participant's death, and in the event of
a Participant's death, payment of any amounts due under the Plan will be made
to, and exercise of any Options (to the extent permitted pursuant to Section 9
of the Plan) may be made by, the Participant's legal representatives, heirs and
legatees.  

    12.4  NON-EXCLUSIVITY OF THE PLAN.  Nothing contained in the Plan is
intended to modify or rescind any previously approved compensation plans or
programs of the Company or create any limitations on


                                          13

<PAGE>

the power or authority of the Board to adopt such additional or other
compensation arrangements as the Board may deem necessary or desirable.

13. SECURITIES LAW AND OTHER RESTRICTIONS.

    Notwithstanding any other provision of the Plan or any agreements entered
into pursuant to the Plan, the Company will not be required to issue any shares
of Common Stock under this Plan, and a Participant may not sell, assign,
transfer or otherwise dispose of shares of Common Stock issued pursuant to
Incentive Awards granted under the Plan, unless (a) there is in effect with
respect to such shares a registration statement under the Securities Act and any
applicable securities laws of a state or foreign jurisdiction or an exemption
from such registration under the Securities Act and applicable state or foreign
securities laws, and (b) there has been obtained any other consent, approval or
permit from any other regulatory body which the Committee, in its sole
discretion, deems necessary or advisable.  The Company may condition such
issuance, sale or transfer upon the receipt of any representations or agreements
from the parties involved, and the placement of any legends on certificates
representing shares of Common Stock, as may be deemed necessary or advisable by
the Company in order to comply with such securities law or other restrictions.

14. PLAN AMENDMENT, MODIFICATION AND TERMINATION.

    The Board may suspend or terminate the Plan or any portion thereof at any
time, and may amend the Plan from time to time in such respects as the Board may
deem advisable in order that Incentive Awards under the Plan will conform to any
change in applicable laws or regulations or in any other respect the Board may
deem to be in the best interests of the Company; provided, however, that no
amendments to the Plan will be effective without approval of the stockholders of
the Company if stockholder approval of the amendment is then required pursuant
to Section 422 of the Code or the rules of the New York Stock Exchange.  No
termination, suspension or amendment of the Plan may adversely affect any
outstanding Incentive Award without the consent of the affected Participant;
provided, however, that this sentence will not impair the right of the Committee
to take whatever action it deems appropriate under Sections 3.2, 4.3 and 11 of
the Plan.

15. EFFECTIVE DATE AND DURATION OF THE PLAN.

    The Plan is effective as of May 9, 1997 or such later date as the Plan is
approved by the Company's stockholders.  The Plan will terminate at midnight on
June 30, 2003, and may be terminated prior to such time to by Board action, and
no Incentive Award will be granted after such termination.  Incentive Awards
outstanding upon termination of the Plan may continue to be exercised, or become
free of restrictions, in accordance with their terms.

                                     ECOLAB INC.

                         1997 NON-EMPLOYEE DIRECTOR DEFERRED
                                  COMPENSATION PLAN

1.  DESCRIPTION.

    1.1  NAME.  The name of the Plan is the "Ecolab Inc. 1997 Non-Employee
Director Deferred Compensation Plan."

    1.2  PURPOSES.  The purposes of the Plan are (a) to provide Qualified
Directors with the opportunity on a one-time basis to convert their existing
accrued benefits under the Director Retirement Plan to balances under this Plan
through credits to their Share Accounts, (b) to provide Qualified Directors who
convert their accrued benefits under the Director Retirement Plan to balances
under this Plan and individuals who first become Qualified Directors at or after
the Effective Time with ongoing periodic credits to their Share Accounts, (c) to
provide Qualified Directors with 50 percent of their Retainer in the form of
credits to their Share Accounts, and (d) to provide Qualified Directors with the
opportunity to defer receipt of Other Director Compensation through credits to
their Share or Cash Accounts.

    1.3  TYPE.  The Plan is maintained primarily for the purpose of providing
deferred compensation for Qualified Directors and is intended to be unfunded for
tax purposes.  The Plan will be construed and administered in a manner that is
consistent with and gives effect to the foregoing.

    1.4  BACKGROUND.  The Company previously adopted the Director Retirement
Plan, the Director Retainer Plan and the Prior Deferred Compensation Plans.  As
of the Effective Time, Qualified Directors must elect either to convert their
existing accrued benefits under the Director Retirement Plan to balances in
their Share Accounts under this Plan, in which case such electing Qualified
Directors (along with individuals first becoming Qualified Directors at or after
the Effective Time) would become entitled to receive the credits to their Share
Accounts pursuant to Section 3.2(b), or to remain under the Director Retirement
Plan, in which case such non-electing Qualified Directors will not be entitled
to receive such annual credits pursuant to Section 3.2(b).  In addition, as of
the Effective Time, the Director Retainer Plan will be terminated, and all
Qualified Directors will thereafter receive 50 percent of their Retainer in the
form of credits to their Share Accounts under this Plan.  Finally, as of the
Effective Time, all Qualified Directors will become entitled to defer receipt of
Other Director Compensation through credits to their Share or Cash Accounts
under this Plan.  Any amounts previously deferred under the Prior Deferred
Compensation Plans will remain subject solely to the terms of such plans, but
all future deferrals of Other Director Compensation will be made solely under
this Plan.

2.  PARTICIPATION.

    2.1  ELIGIBILITY.  
    
         (a)  Each individual who is a Qualified Director both immediately
    prior to and immediately following the Effective Time is eligible to elect
    to convert his or her then existing accrued benefit under the Director
    Retirement Plan to a balance in his or her Share Account pursuant to
    Section

<PAGE>

    3.2(a).

         (b)  Each individual (i) who has elected to convert his or her accrued
    benefit under the Director Retirement Plan as described in Section 2.1(a)
    or (ii) who first becomes a Qualified Director at or after the Effective
    Time, and, in the case of both clause (i) and (ii), who is a Qualified
    Director at any point during the calendar quarter with respect to which a
    credit is made pursuant to Section 3.2(b) is eligible to have such credit
    made to his or her Share Account pursuant to Section 3.2(b).  

         (c)  Each individual who is a Qualified Director at any point during
    the calendar quarter with respect to which a credit is made pursuant to
    Section 3.2(c) is eligible to have such credit made to his or her Share
    Account pursuant to Section 3.2(c).

         (d)  Each individual who is a Qualified Director on the first day of a
    calendar year is eligible to make deferral elections pursuant to Section
    3.2(d) with respect to such calendar year.  An individual who becomes a
    Qualified Director after the first day of the calendar year is eligible to
    make a deferral election pursuant to Section 3.2(d) with respect to the
    remainder of such calendar year.  A Participant who receives a
    distribution, pursuant to Section 4.1(d)(i) or (iv), is not eligible to
    elect additional deferrals pursuant to Section 3.2(d) until the one-year
    anniversary of such distribution.  

    2.2  CEASING TO BE ELIGIBLE.  An individual who ceases to be a Qualified
Director is not eligible to make or receive further deferral credits pursuant to
Section 3.2 other than such credits relating to the period prior to such
cessation.

    2.3  CONDITION OF PARTICIPATION.  Each Qualified Director, as a condition
of participation in the Plan, is bound by all the terms and conditions of the
Plan and the Plan Rules, including but not limited to the reserved right of the
Company to amend or terminate the Plan, and must furnish to the Administrator
such pertinent information, and execute such election forms and other
instruments, as the Administrator or Plan Rules may require by such dates as the
Administrator or Plan Rules may establish.

    2.4  TERMINATION OF PARTICIPATION.  A Participant will cease to be such as
of the date on which he or she is not then eligible to make deferrals and his or
her entire Account balance has been distributed.

    2.5  RIGHTS UNDER DIRECTOR RETIREMENT PLAN.  Each Qualified Director who
elects to convert his or her then existing accrued balance under the Director
Retirement Plan to a balance in the Share Account under this Plan pursuant to
Section 3.2(a) will, as of the Effective Time and without further action on the
part of such Qualified Director, no longer be eligible to participate in, or to
receive any benefit pursuant to, the Director Retirement Plan.

3.  BENEFITS.

    3.1  PARTICIPANT ACCOUNTS.  For each Participant, the Administrator will
establish and maintain a Cash Account, a Share Account or both to evidence
amounts credited with respect to the Participant pursuant to Sections 3.2 and
3.3.  

    3.2  DEFERRAL CREDITS.   


                                          2

<PAGE>

         (a)  Each individual who is a Qualified Director who satisfies the
    requirements of Section 2.1(a) is eligible to elect to convert his or her
    then existing accrued benefit under the Director Retirement Plan to a
    balance in the Share Account of such Qualified Director under this Plan. 
    To make such election, a properly completed election form must be received
    by the Administrator by April 30, 1997.  The Share Account of a Qualified
    Director who makes such an election will be credited as of the Effective
    Time with the number of full Share Units determined by dividing the amount
    set forth with respect to such Qualified Director on Exhibit A, which
    amount represents the entire accrued benefit of such Qualified Director
    under the Director Retirement Plan as of the Effective Time, by the average
    of the Market Price for the period from February 7, 1997 through May 8,
    1997 and rounding such quotient up to the next highest multiple of 50.

         (b)  As of the first day of the calendar quarter that first follows
    the Effective Time and on the first day of each calendar quarter
    thereafter, the Share Account of each individual who satisfies the
    requirements of Section 2.1(b) will be credited with the number of full and
    fractional Share Units determined by multiplying the number of Quarterly
    Share Units by a fraction, the numerator of which is the number of days
    during such calendar quarter (or the number of days after May 8, 1997 with
    respect to the quarter ended June 30, 1997) that the individual served as a
    Qualified Director and the denominator of which is the total number of days
    in such calendar quarter. 

         (c)  As of the first day of the calendar quarter that first follows
    the Effective Time and on the first day of each calendar quarter
    thereafter, the Share Account of each individual who is a Qualified
    Director at any time during the immediately preceding calendar quarter,
    will be credited with the number of full and fractional Share Units
    determined by (i) dividing an amount equal to 50 percent of the Retainer
    payable by the Company to Qualified Directors for such calendar quarter by
    the Market Price on the date as of which such credit is made and (ii)
    multiplying such quotient by a fraction, the numerator of which is the
    number of days during such calendar quarter (or the number of days after
    May 8, 1997 with respect to the quarter ended June 30, 1997) that the
    individual served as a Qualified Director and the denominator of which is
    the total number of days in such calendar quarter.

         (d)  Elective deferrals of Other Director Compensation will be made in
    accordance with the following rules:

              (i)  Commencing with respect to services to be performed after
         May 8, 1997, a Qualified Director may elect to defer all or any
         portion of his or her Other Director Compensation relating to his or
         her services as a Qualified Director during a calendar year.  Any
         portion so elected will automatically apply to the Participant's Other
         Director Compensation for the year as adjusted from time to time.  

             (ii)  An election made pursuant to this Section 3.2(d) will not be
         effective unless it is made on a properly completed election form
         received by the Administrator by the last day of the calendar year
         immediately preceding the calendar year to which the election relates
         or, in the case of an individual who becomes a Qualified Director
         after the first day of the calendar year, within 30 days after the
         date such individual becomes a Qualified Director.  Notwithstanding
         the foregoing, with respect to an initial deferral election pursuant
         to Section 3.2(d) that is made in connection with the adoption of this
         Plan, such election will be effective if received by the Administrator
         by April 30, 1997.  Any such election applies only to Other Director
         Compensation relating to services performed after the effective date
         of the election.


                                          3

<PAGE>

            (iii)  In conjunction with each deferral election made pursuant to
         this Section 3.2(d), a Qualified Director must elect, in accordance
         with and subject to Plan Rules, how the deferral is to be allocated
         (in increments of five percent only) among his or her Cash Account and
         Share Account.  Such an election is irrevocable after the latest date
         by which the deferral election to which it relates must be received by
         the Administrator to be effective.  

             (iv)  Deferrals of Other Director Compensation pursuant to this
         Section 3.2(d) will be credited to a Qualified Director's Cash Account
         or Share Account, as the case may be, as of the first day of the
         calendar month first following the date on which the Other Director
         Compensation has been earned and would otherwise be payable but for
         his or her deferral election.  Such credits to the Qualified
         Director's Cash Account will be in United States dollars in an amount
         equal to the amount of the deferral allocated to the Cash Account by
         the Qualified Director.  Such credits to a Qualified Director's Share
         Account will be the number of full and fractional Share Units
         determined by dividing the United States dollar amount of the deferral
         allocated by the Qualified Director to the Share Account by the Market
         Price on the date as of which the credit is made.  

    3.3  EARNINGS CREDITS.        

         (a)  CASH ACCOUNT.  As of the first day of each calendar quarter, a
    Participant's Cash Account will be credited with interest, calculated on
    the basis of the balance in the Participant's Cash Account on the first day
    of each month of the immediately preceding calendar quarter, at the Prime
    Rate of Morgan Guaranty Trust Company of New York in effect on the first
    day of each such month.

         (b)  SHARE ACCOUNT.  

              (i)  As of the first day of the calendar quarter first following
         the date on which dividends are paid on Shares, a Participant's Share
         Account will be credited with that number of full and fractional Share
         Units determined by dividing the dollar amount of the dividends that
         would have been payable to the Participant if the number of Share
         Units credited to the Participant's Share Account on the record date
         for such dividend payment had then been Shares registered in the name
         of such Participant by the Market Price on the date as of which the
         credit is made. 

             (ii)  In the event of a reorganization, recapitalization, stock
         split, stock dividend, combination of shares, merger, consolidation,
         rights offering or any other change in the Company's corporate
         structure or Shares, the Administrator will make such adjustment, if
         any, as the Administrator may deem appropriate in the number and kind
         of Share Units credited to Share Accounts.

    (3.4)     VESTING.  Subject to Section 4.1(d)(iii), each Participant always
has a fully vested nonforfeitable interest in his or her Account.

4.  DISTRIBUTION.

    4.1  DISTRIBUTION TO PARTICIPANT.  


                                          4

<PAGE>


         (a)  FORM.  Distribution to a Participant will be made in the form of
    a lump sum payment unless (i) the Participant elects, on a properly
    completed form, to receive his or her distribution in the form of annual
    installment payments for a period of not more than 10 years and (ii) other
    than cessation resulting from Disability, the date on which he or she
    ceases to be a member of the Board follows by more than one year the date
    on which a properly completed election form is received by the
    Administrator.  Any election made pursuant to this Section 4.1(a) may be
    changed from time to time upon the Administrator's receipt of a properly
    completed form, provided that, other than cessation resulting from
    Disability, such change will not be valid and will not have any effect
    unless it is made on a properly completed form received by the
    Administrator more than one year prior to a Participant's cessation of
    service as member of the Board.  The most recently received election to
    change has no effect on any previously received election to change until
    the most recently received election becomes effective at which time any
    previously received election will automatically be void.  (For example, if
    the Administrator receives a properly completed election to change on July
    1 of year 1 and another properly completed election to change on September
    1 of year 1, the July 1 election will become effective on July 1 of year 2
    and will remain in effect through August 30 of year 2.  On September 1 of
    year 2, the September 1 election to change will become effective.)  Any
    election made pursuant to this Section 4.1(a) will apply to the entire
    balance of the Participant's Account attributable to deferral credits with
    respect to the period through the date on which he or she ceases to be a
    member of the Board.  Any distribution from a Participant's Cash Account
    will be made in cash only.  Subject to Section 4.3, any distribution from a
    Participant's Share Account will be made in full Shares only and cash in
    lieu of any fractional Share.  

         (b)  TIME.  Distribution to a Participant will be made or commence on
    or as soon as administratively practicable after the first day of the
    calendar quarter that follows the date on which the Participant ceases to
    be a member of the Board.

         (c)  AMOUNT.  

              (i)  CASH ACCOUNT.

                   (A)  LUMP SUM.  The amount of a lump sum payment from a
              Participant's Cash Account will be equal to the balance of the
              Account as of the first day of the calendar month coinciding with
              or immediately preceding the date on which the payment is made.

                   (B)  INSTALLMENTS.  The amount of an installment payment
              from a Participant's Cash Account will be determined by dividing
              the balance of the Account as of the first day of the calendar
              month coinciding with or immediately preceding the date on which
              the payment is made by the total number of remaining payments
              (including the current payment).

             (ii)  SHARE ACCOUNT.

                   (A)  LUMP SUM.  A lump sum distribution from a Participant's
              Share Account will consist of the number of Shares equal to the
              number of full Share Units credited to the Account as of the
              first day of the calendar month coinciding with or immediately
              preceding the date on which the distribution is made plus cash in
              lieu of any fractional Share Units then credited to the Account
              in an amount based on the


                                          5

<PAGE>

              Market Price on that date.

                   (B)  INSTALLMENTS.  Installment distributions from a
              Participant's Share Account, other than the final distribution,
              will consist of the number of Shares determined by dividing the
              number of full Share Units credited to the Account as of the
              first day of the calendar month coinciding with or immediately
              preceding the date on which the distribution is made by the total
              number of remaining payments (including the current payment) and
              rounding the quotient to the next higher full Share.  The amount
              of the final payment will be determined in accordance with clause
              (A).

         (d)  SPECIAL RULES.  The provisions of this Section 4.1(d) will apply
    notwithstanding Section 4.1(a), (b) or (c) or any election by a Participant
    to the contrary; provided, however, that, prior to the time that a
    Participant ceases to be a member of the Board, distributions pursuant to
    Sections 4.1(d)(i) and (iv) may only be made with respect to amounts
    credited to a Participant's Account pursuant to Sections 3.2(c) and (d) and
    any earnings with respect thereto credited pursuant to Section 3.3.

              (i)  WITHDRAWALS DUE TO UNFORESEEABLE EMERGENCY.  A distribution
         will be made to a Participant from his or her Share or Cash Account if
         the Participant submits a written distribution request to the
         Administrator and the Administrator determines that the Participant
         has experienced an Unforeseeable Emergency.  The amount of the
         distribution may not exceed the lesser of (a) the amount necessary to
         satisfy the emergency, as determined by the Administrator, or (b) the
         balance of the Participant's Account as of the date of the
         distribution determined in accordance with Section 4.1(c).  Payments
         made on account of an Unforeseeable Emergency will not be made to the
         extent that such Unforeseeable Emergency is or may be relieved through
         reimbursement or compensation by insurance or otherwise, by
         liquidation of the Participant's assets (to the extent that such
         liquidation would not itself cause severe financial hardship) or by
         cessation of deferrals under Section 3.2(d).  Any distribution
         pursuant to this Section 4.1(d)(i) will be made in the form of a lump
         sum payment (in cash from the Cash Account and in Shares from the
         Share Account) as soon as administratively practicable after the
         Administrator's determination that the Participant has experienced an
         Unforeseeable Emergency and will be made first from the Participant's
         Cash Account and then from the Participant's Share Account, with the
         amount distributed from the Share Account determined based upon the
         Market Price as of the first day of the calendar month coinciding with
         or immediately preceding the date on which the distribution is made.

             (ii)  SMALL BENEFITS.  If the balance of the Cash Account of a
         Participant who has ceased to be a member of the Board is less than
         $5,000 as of the first day of a calendar month, such balance will be
         distributed to the Participant in the form of a lump sum cash payment
         as soon as administratively practicable thereafter.  

            (iii)  FORFEITURE PROVISIONS.  Other than amounts credited to a
         Participant's Account pursuant to Sections 3.2(c) and (d) and any
         earnings with respect thereto credited pursuant to Section 3.3,
         neither the Company nor the Trust will be obligated to pay or provide
         to a Participant any future benefits under this Plan, if the Board
         determines that such Participant, without the consent of the Company
         and whether before or after such Participant ceases to serve as a
         director of the Company, has engaged in an activity that is
         competitive or


                                          6

<PAGE>

         materially detrimental to the Company's business.

        (iv)  ACCELERATED DISTRIBUTION.  A Participant may, at any time, elect
    an immediate distribution of his or her Account in an amount equal to 90
    percent of the balance of the Account as of the date of the distribution
    determined in accordance with Section 4.1(c), in which case the remaining
    balance of the Account will be forfeited.  The distribution will be made in
    the form of a lump sum payment as soon as administratively practicable
    after the Administrator's receipt of a written application on a form
    furnished by the Administrator.  Any distribution from a Participant's Cash
    Account will be made in cash only.  Any distribution from a Participant's
    Share Account will be made in full Shares only and cash in lieu of any
    fractional Share.

         (c)  REDUCTION OF ACCOUNT BALANCE.  The balance of the Account from
    which a distribution is made will be reduced by the amount of the
    distribution as of the date of the distribution.

    4.2  DISTRIBUTION TO BENEFICIARY.  

         (a)  FORM.  In the event of a Participant's death, the balance of the
    Participant's Account will be distributed to the Participant's Beneficiary
    in a lump sum payment whether or not payments had commenced to the
    Participant in the form of installments prior to his or her death.  Any
    distribution from a Participant's Cash Account will be made in cash and any
    distribution from a Participant's Share Account will be made in full Shares
    and cash in lieu of any fractional Share.

         (b)  TIME.  Distribution to a Beneficiary will be made as soon as
    administratively practicable after the date on which the Administrator
    receives notice of the Participant's death.  

         (c)  AMOUNT.  The amount of the payment will be determined in
    accordance with Section 4.1(c).

         (d)  REDUCTION OF ACCOUNT BALANCE.  The balance of the Account from
    which a distribution is made will be reduced by the amount of the
    distribution as of the date of the distribution.

         (e)  BENEFICIARY DESIGNATION.

              (i)  Each Participant may designate, on a form furnished by the
         Administrator, one or more primary Beneficiaries or alternative
         Beneficiaries to receive all or a specified part of his or her Account
         after his or her death, and the Participant may change or revoke any
         such designation from time to time.  No such designation, change or
         revocation is effective unless executed by the Participant and
         received by the Administrator during the Participant's lifetime.

             (ii)  If, for all or any portion of his or her Account, a
         Participant fails to designate a Beneficiary, revokes a Beneficiary
         designation without naming another Beneficiary or designates one or
         more Beneficiaries, none of whom survives the Participant or exists at
         the time in question, such Account or portion will be paid to the
         Participant's surviving spouse or, if the Participant is not survived
         by a spouse, to the representative of the Participant's estate.


                                          7

<PAGE>

            (iii)  The automatic Beneficiaries specified above and, unless the
         designation otherwise specifies, the Beneficiaries designated by the
         Participant, become fixed as of the Participant's death so that, if a
         Beneficiary survives the Participant but dies before the receipt of
         the payment due such Beneficiary, the payment will be made to the
         representative of such Beneficiary's estate.  Any designation of a
         Beneficiary by name that is accompanied by a description of
         relationship or only by statement of relationship to the Participant
         is effective only to designate the person or persons standing in such
         relationship to the Participant at the Participant's death.

    4.3  LIMITATIONS ON SHARE DISTRIBUTIONS.  Notwithstanding any other
provision of the Plan to the contrary, neither the Company nor the Trustee is
required to issue or distribute any Shares under this Plan, and a distributee
may not sell, assign, transfer or otherwise dispose of Shares issued or
distributed pursuant to the Plan, unless (a) there is in effect with respect to
such Shares a registration statement under the Securities Act of 1933 and any
applicable state securities laws or an exemption from such registration under
the Securities Act of 1933 and applicable state securities laws, and (b) there
has been obtained any other consent, approval or permit from any other
regulatory body which the Company deems necessary or advisable.  The Company or
the Trustee may condition such issuance, distribution, sale or transfer upon the
receipt of any representations or agreements from the parties involved, and the
placement of any legends on certificates representing Shares, as may be deemed
necessary or advisable by the Company in order to comply with such securities
laws or other restrictions.

    4.4  PAYMENT IN EVENT OF INCAPACITY.  If any individual entitled to receive
any payment under the Plan is, in the judgment of the Administrator, physically,
mentally or legally incapable of receiving or acknowledging receipt of the
payment, and no legal representative has been appointed for the individual, the
Administrator may (but is not required to) cause the payment to be made to any
one or more of the following as may be chosen by the Administrator:  the
Beneficiary (in the case of the incapacity of a Participant); the institution
maintaining the individual; a custodian for the individual under the Uniform
Transfers to Minors Act of any state; or the individual's spouse, children,
parents, or other relatives by blood or marriage.  The Administrator is not
required to see to the proper application of any such payment, and the payment
completely discharges all claims under the Plan against the Company, the Plan
and the Trust to the extent of the payment.

5.  SOURCE OF PAYMENTS; NATURE OF INTEREST.

    5.1  ESTABLISHMENT OF TRUST.  The Company may establish a Trust with an
independent corporate trustee.  The Trust must be a grantor trust with respect
to which the Company is treated as grantor for purposes of Code section 677 and
must provide that, upon the insolvency of the Company, Trust assets will be used
to satisfy claims of the Company's general creditors.  The Company will pay all
taxes of any and all kinds whatsoever payable in respect of the Trust assets or
any transaction with respect to the Trust assets.  The Company may from time to
time transfer to the Trust cash, marketable securities or other property
acceptable to the Trustee in accordance with the terms of the Trust.

    5.2  SOURCE OF PAYMENTS. 

         (a)  The Company will pay, from its general assets, the benefits
    pursuant to Section 4 attributable to a Participant's Account, and all
    costs, charges and expenses relating thereto.

         (b)  The Trustee will make distributions to Participants and
    Beneficiaries from the Trust


                                          8

<PAGE>

    in satisfaction of the Company's obligations under the Plan in accordance
    with the terms of the Trust.  The Company is responsible for paying any
    benefits attributable to a Participant's Account that are not paid by the
    Trust.

    5.3  STATUS OF PLAN.  Nothing contained in the Plan or Trust is to be
construed as providing for assets to be held for the benefit of any Participant
or any other person or persons to whom benefits are to be paid pursuant to the
terms of the Plan, the Participant's or other person's only interest under the
Plan being the right to receive the benefits set forth herein.  The Trust is
established only for the convenience of the Company and the Participants, and no
Participant has any interest in the assets of the Trust prior to distribution of
such assets pursuant to the Plan.  Until such time as Shares are distributed to
a Participant, Beneficiary of a deceased Participant or other person, he or she
has no rights as a shareholder with respect to any Shares Units credited to a
Share Account pursuant to the Plan.  To the extent that the Participant or any
other person acquires a right to receive benefits under the Plan or the Trust,
such right is no greater than the right of any unsecured general creditor of the
Company.

    5.4  NON-ASSIGNABILITY OF BENEFITS.  The benefits payable under the Plan
and the right to receive future benefits under the Plan may not be anticipated,
alienated, sold, transferred, assigned, pledged, encumbered, or subjected to any
charge or legal process.

6.  AMENDMENT AND TERMINATION.

    6.1  AMENDMENT.

         (a)  The Company reserves the right to amend the Plan at any time to
    any extent that it may deem advisable.  To be effective, an amendment must
    be stated in a written instrument approved in advance or ratified by the
    Board and executed in the name of the Company by its Chief Executive
    Officer or President and attested by the Secretary or an Assistant
    Secretary.

         (b)  An amendment adopted in accordance with Section 6.1(a) is binding
    on all interested parties as of the effective date stated in the amendment;
    provided, however, that no amendment will have any retroactive effect so as
    to deprive any Participant, or the Beneficiary of a deceased Participant,
    of any benefit to which he or she is entitled under the terms of the Plan
    in effect immediately prior to the effective date of the amendment,
    determined as if such Participant had terminated service as a director
    immediately prior to the effective date of the amendment.  

         (c)  Without limiting Section 6.1(a), the Company reserves the right
    to amend this Plan to change the method of determining the earnings
    credited to Participants' Accounts pursuant to Section 3.3 and to apply
    such new method not only with respect to the portion of the Accounts
    attributable to credits made after the date on which such amendment is
    adopted but also with respect to the portion of the Accounts attributable
    to credits made prior to the date on which such amendment is adopted and
    regardless of whether such new method would result in materially lower
    earnings credits than the old method.

         (d)  The provisions of the Plan in effect at the termination of a
    Participant's service as a director will, except as otherwise expressly
    provided by a subsequent amendment, continue to apply to such Participant.

which Participants have become entitled prior to the effective date of the
termination will continue to be paid in accordance with the provisions of

named person and may from time to time revoke such authority and delegate it to
another person.  

    8.2  PLAN RULES AND REGULATIONS.  The Administrator has the discretionary
power and authority to make such Plan Rules as the Administrator determines to
be consistent with the terms, and necessary or advisable in connection with the
administration, of the Plan and to modify or rescind any such Plan Rules.  In

<PAGE>

for amounts credited with respect to non-U.S. resident Participants.

liabilities, losses, costs and expenses (including legal fees) of every kind and
nature that may be imposed on, incurred by, or asserted against such person at
any time by reason of such person's services in connection with the Plan, but
only if such person did not act dishonestly or in bad faith or in willful
violation of the law or regulations under which such liability, loss, cost or
expense arises.  The Company has the right, but not the obligation, to select
counsel and control the defense and settlement of any action for which a person

9.  MISCELLANEOUS.

    9.1  WITHHOLDING AND OFFSETS.  The Company and the Trustee retain the right

Company and the Trustee may offset against amounts payable to a Participant or
Beneficiary under the Plan any amounts then owing to the Company by such
Participant or Beneficiary.  The Company or the Trustee, as the case may be, in
its sole discretion, may permit Participants to elect whether to satisfy their
obligations under this Section 9.1 by having such amounts withheld from any
compensation, deferral and/or benefit payment pursuant to the Plan or by
remitting such amounts to the Company or the Trustee, or by a combination of
such methods.

    9.2  OTHER BENEFITS.  Neither amounts deferred nor amounts paid pursuant to
the Plan constitute salary or compensation for the purpose of computing benefits
under any other benefit plan, practice, policy or procedure of the Company
unless otherwise expressly provided thereunder.

    9.3  NO WARRANTIES REGARDING TAX TREATMENT.  The Company makes no
warranties regarding the tax treatment to any person of any deferrals or
payments made pursuant to the Plan, and each Participant will hold the
Administrator and the Company and their officers, directors, employees, agents
and advisors harmless from any liability resulting from any tax position taken
in good faith in connection with the Plan.

    9.4  NO RIGHTS TO CONTINUED SERVICE CREATED.  Neither the establishment of
or participation in the Plan gives any individual the right to continued service
on the Board or limits the right of the Company or its stockholders to terminate
or modify the terms and conditions of service of such individual on the Board or
otherwise deal with any individual without regard to the effect that such action
might have on him or her


                                          13

<PAGE>

with respect to the Plan.

    9.5  SUCCESSORS.  Except as otherwise expressly provided in the Plan, all
obligations of the Company under the Plan are binding on any successor to the
Company whether the existence of such successor is the result of a direct or
indirect purchase, merger, consolidation or otherwise of all or substantially
all of the business and/or assets of the Company.

    9.6  SHARES AVAILABLE FOR ISSUANCE.

         (a)  MAXIMUM NUMBER OF SHARES AVAILABLE.  Subject to adjustment as
    provided in subsection (b) below, the maximum number of Shares that will be
    available for issuance under the Plan will be 125,000 Shares.  The Shares
    available for issuance under the Plan may, at the election of the
    Administrator, be either treasury shares or shares authorized but unissued,
    and, if treasury shares are used, all references in the Plan to the
    distribution or issuance of Shares will, for corporate law purposes, be
    deemed to mean the transfer of shares from treasury.

         (b)  ADJUSTMENT TO SHARES.  In the event of any reorganization,
    merger, consolidation, recapitalization, liquidation, reclassification,
    stock dividend, stock split, combination of shares, rights offering,
    divestiture or extraordinary dividend (including a spin-off) or any other
    change in the Company's corporate structure or the Shares, the
    Administrator (or, if the Company is not the surviving corporation in any
    such transaction, the board of directors of the surviving corporation) will
    make appropriate adjustment (which determination will be conclusive) as to
    the number and kind of securities or other property (including cash)
    available for issuance or distribution under the Plan.

                            DESCRIPTION OF ECOLAB INC.
                            MANAGEMENT INCENTIVE PLAN


     The Ecolab Inc. Management Incentive Plan ("MIP") is not set forth in a 
formal plan document. Set forth below is a description of the MIP as it 
applies to the executive officers of Ecolab Inc. (the "Company").

     The MIP is a cash-based annual incentive plan that focuses executives' 
attention on achieving competitive annual business goals. The Compensation 
Committee of the Company's Board of Directors (the "Committee"), with input 
from management, sets specific performance goals at the beginning of each 
year and communicates them to the Company's executives. The Committee also 
establishes median awards, which are set at a level which approximates median 
annual incentive targets expressed as a percentage of base salary of a 
comparator group consisting of a broad range of United States manufacturing 
and service companies. Achievement of median performance goals will result in 
a median award, while achievement of performance levels below or above the 
median performance goal will result in minimum, premium or maximum awards.

     Executives with corporate-wide responsibility earn awards based solely 
on the achievement of Earnings Per Share ("EPS") goals. The Committee 
establishes annual EPS levels that must be achieved to receive minimum, 
median, premium and maximum awards. The compounded annual EPS growth over 
three-year periods for the Standard & Poor's 500 Index is the basis for the 
EPS goals.

     Executives with business-unit responsibility earn MIP awards by meeting 
unit-specific operating income goals. Other financial or strategic factors 
including, but not limited to, sales, cash flow and management of assets and 
working capital, may also affect the size of the awards provided that the 
operating income thresholds are met. The weight of each performance measure 
varies among business units. Notwithstanding the above, the performance 
measures for certain executives with business-unit responsibility will also 
include achievement of EPS goals.

     The Committee, in general, makes awards based strictly on level of 
achievement against pre-established goals. However, under the MIP, the 
Committee may, in its sole discretion, make awards at a level higher or lower 
than that determined by strict application of achievement against goals based 
upon such other business criteria as the Committee determines appropriate.

FINANCIAL DISCUSSION

The following discussion and analysis provides information which 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.


1996 Overview 1996 marked the fifth consecutive year that Ecolab achieved record
financial results. As a result
of its strong performance, Ecolab's stock price rose 25 percent during 1996,
following an increase of over 40 percent in 1995. The company's more significant
accomplishments included:

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

- - For the second year in a row, all of the company's established
businesses achieved record sales and income results.

- - Consolidated net sales increased 11 percent reaching a record of nearly $1.5
billion.

- - Net income reached a record $113 million, or $1.75 per share. Net income per
common share increased 17 percent, exceeding the company's long-term objective
of 15 percent.

- - Consolidated cash flow from operating activities increased more than 50
percent and debt was maintained at a very low level. Ecolab maintained its long-
term financial objective of an investment grade balance sheet and the company's
debt was rated within the "A" categories by the major rating agencies.

- - Return on beginning shareholders' equity reached an all time high of 24.8
percent. This was the fifth consecutive year that the company exceeded its long-
term financial objective to achieve a 20 percent return on beginning
shareholders' equity.

- - The company's equity in earnings of the Henkel-Ecolab joint venture reached a
record $13 million for 1996. Also, one of Ecolab's financial executives became
the new chief financial officer of Henkel-Ecolab in December 1996.

- - The company increased its annual dividend rate for the
fifth consecutive year. The annual dividend rate was increased 14 percent to an
annual rate of $0.64 per common share.
The company has paid dividends on its common stock for
60 consecutive years.

- - During 1996, the company made two significant business acquisitions. In
February, the company acquired Huntington Laboratories, Inc., a supplier of
sanitizing and infection-control products for the U.S. healthcare market and a
supplier of gym floor finishes. Huntington had annual sales of approximately $50
million and has become a part of the company's Professional Products Division.

  In August, the company acquired the Monarch Division
of H.B. Fuller Company of Saint Paul, Minnesota. Monarch is
a provider of cleaning and sanitizing products and services to
the food processing and farm markets in the United States
and Canada. Monarch had annual sales of approximately
$30 million and has become a part of the company's Food
and Beverage Division.

  These acquisitions have been accounted for as purchases and, accordingly, the
results of their operations have been included in the company's financial
statements from the dates of acquisition.

  Consolidated net sales were nearly $1.5 billion in 1996
and increased 11 percent over net sales of $1.3 billion in 1995. Both the
company's United States and International operations contributed to this sales
improvement. Businesses acquired during 1996 and during late 1995 accounted for
approximately

one-half of the growth in sales for 1996. New product introductions also
continued to contribute significantly to sales growth, with additions to the
sales-and-service force, competitive gains and generally good business
conditions in the hospitality and lodging industries also adding to the sales
improvement.

  Consolidated operating income reached $185 million in 1996, an increase of 14
percent over operating income of
$163 million in 1995. This improvement included good growth in the company's
core U.S. Institutional operations and double-digit growth in all of the
company's other U.S. businesses and
in all major regions of International operations. The consolidated operating
income margin was 12.4 percent in 1996, an improvement over the operating income
margin of 12.1 percent in 1995. The increase in the operating income margin
reflected an improvement in selling, general and administrative expenses as a
percentage of net sales, partially offset by a decrease in the gross profit
margin. The gross profit margin was 54.7 percent in 1996, a decrease compared to
the gross profit margin of 55.0 percent in 1995. The decrease in gross profit
margin reflected changes in the composition of sales between divisions and
geographic areas, limited selling price increases due to continuing market
pressures and increased raw material costs. Selling, general and administrative
costs were 42.3percent of net sales in 1996 compared to 42.9 percent of net
sales in 1995. This improvement in selling, general and administrative costs was
primarily due to improved sales productivity levels and
the company's continuing cost control efforts. The company's emphasis on cost
controls has resulted in significant cost savings over the last few years.
Therefore, the company expects that it will be more difficult to achieve
significant improvement in the comparison of these expenses as a percentage of
net sales in the future.

  Net income for 1996 was $113 million, an increase of 14percent over net income
of $99 million in 1995. The increase in net income reflected strong operating
income performance and increased equity in earnings of the Henkel-Ecolab joint
venture, partially offset by increases in net interest expense
and income taxes. Net income per common share was $1.75 for 1996 and increased
17 percent over 1995's net income
per common share of $1.50. The comparison of net income per common share
benefitted from a smaller number of average shares outstanding in 1996,
principally 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.


1995 COMPARED WITH 1994

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. New product introductions and a larger
sales-and-service force made significant contributions to the sales improvement.

  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, 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, 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.

  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 on a basis consistent with
the way it has been reported subsequent to the company's merger with Kay. The
pro forma adjustments are discussed in detail in Note 5 of the notes to
consolidated financial statements. 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 common share of
$1.50 increased 12 percent over pro forma net income per common share of $1.34
in 1994. The comparison of net income per common share benefitted from a smaller
number of average shares outstanding in 1995 due to shares purchased under the
mid-1995 self-tender offer.

  Sales of the company's United States operations exceeded $1.1 billion in 1996,
an increase of 12 percent over United States sales of $1.0 billion in 1995. U.S.
sales growth reflected business acquisitions and the benefits of significant new
product introductions, as well as new customers, retention of key customers,
investments in the sales-and-service force and continued good business trends in
the hospitality and lodging industries. However, selling price increases were
limited due to tight pricing conditions in several of the markets in which the
company does business. Business acquisitions accounted for approximately one-
half of the increase in United States sales. Sales of the U.S. Institutional
Division increased 4 percent for 1996. Institutional sales growth reflected
competitive gains and continued strong growth in its Ecotemp program and the
specialty products group. Pest Elimination sales increased 12percent over the
prior year reflecting new business and a continued high retention of key
customers. Kay's United States operations reported sales growth of 11 percent
for 1996 due to new customer business and the growth of the large quickservice
chains, which are the core of Kay's business. The Textile Care Division reported
sales growth of 9 percent for 1996 with continued success in sales of new
products and double-digit growth in sales to the commercial laundry market.
Sales of the company's Professional Products Division (formerly the Janitorial
Division) nearly doubled due to the February 1996 acquisition of Huntington
Laboratories. Excluding sales of the Huntington operations, Professional
Product's sales for 1996 increased 3 percent over 1995 principally due to sales
growth of its Airkem products. Financial results of the Food and


                                     [GRAPH]


Beverage Division increased 13 percent for 1996 and included the operations of
Monarch since its acquisition from H.B. Fuller in August 1996. Excluding Monarch
sales, Food and Beverage sales growth was 5 percent for 1996, and reflected new
customer gains and good growth in sales to the beverage and food processing
markets. Sales of the company's recently formed Water Care Services Division
more than doubled during 1996 due to the annualization of sales from business
acquisitions and sales gained by successfully leveraging its alliances with
Ecolab's other divisions.

  Operating income for the company's United States businesses totaled $165
million for 1996 and increased 12 percent over operating income of $147 million
in 1995. The growth in operating income included good growth in the company's
core U.S. Institutional business and double-digit increases in operating income
of all of the company's other U.S. divisions. The U.S. operating income margin
was 14.4 percent, up slightly compared to the operating income margin of 14.3
percent in 1995. The improvement in the operating income margin reflected higher
sales levels, sales productivity gains and the benefits of companywide cost
control programs. The company's United States business continued to invest in
its sales-and-service force with the addition of more than 350 new U.S. sales-
and-service personnel, including Huntington and Monarch associates, during 1996.
Operating income of the Huntington and Monarch businesses acquired in 1996 was
not significant.

1995 COMPARED WITH 1994

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. The growth in United States sales reflected the
benefits of significant new product introductions. 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 and included good growth in sales to new customers. The Textile Care
Division reported a sales increase of 7 percent for 1995, which included double-
digit growth in commercial laundry and hospitality market sales. Sales of the
Professional Products Division increased 5 percent over the prior year.
Professional Products 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 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. The operating income margin was 14.3 percent for 1995, unchanged from
the prior year. Operating income growth included continued good growth in the
U.S. Institutional Division and double-digit growth in 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, which were partially offset by the negative
effects of higher raw material costs
and competitive pricing pressures.

  The company's International business consists of Canadian, Asia Pacific, Latin
American and South African operations and the international operations of Kay.
Net sales of the company's wholly-owned International operations reached $341
million in 1996, a 10 percent increase over sales of $311 million in 1995.
International's sales growth reflected the benefits of business acquisitions and
sales of new products. Business acquisitions accounted for approximately 40
percent of International's sales growth over 1995. Changes in currency
translation had a negative impact on sales, particularly in the Asia Pacific
region. Excluding the effects of currency translation, International recorded
sales growth of 14 percent for 1996. Asia Pacific, International's largest
operation, reported sales growth of 4 percent for 1996. However, when measured
in local currencies, the Asia Pacific region had sales growth of 9 percent, with
double-digit growth in Japan and New Zealand and modest growth in Australia.
Asia Pacific sales results included good performances in sales to the
Institutional and Food and Beverage markets. Reported sales of the Latin
American region


                                     [GRAPH]


increased 13 percent over the prior year. Excluding the effects of currency
translation, Latin America recorded sales growth of 16 percent for 1996, which
included a continuation of significant double-digit growth in Brazil and good
sales growth in Mexico and Puerto Rico. Sales in Canada increased 9 percent over
sales in 1995 and reflected the benefits of the Huntington and Monarch
acquisitions and good growth in sales to Institutional markets. Sales in South
Africa more than doubled over the prior year, reflecting the annualization of
sales from businesses acquired in late 1995. Sales of Kay's international
operations increased 16 percent for 1996, as it continued to expand service to
locations where its large corporate customers do business.

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

  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.

FINANCIAL DISCUSSION

1995 COMPARED WITH 1994

International revenues for 1995 of $311 million increased 17 percent over
revenues of $266 million in 1994. The effects of currency translation did not
have a significant impact on overall International sales growth. Asia Pacific
reported sales growth of 14 percent for 1995, which included double-digit growth
in the East Asia region and New Zealand, modest growth in Japan and flat results
in Australia. 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. 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 the Professional Products markets and a modest increase in
sales to the Institutional and Textile Care markets. International sales in 1995
also included approximately $6 million of sales from two businesses in South
Africa which were acquired during 1995. Sales of Kay's International operations
increased 18 percent for 1995.

  Operating income for International operations totaled $20 million in 1995, a
32 percent increase over 1994's operating income of $15 million. The operating
income margin 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.

HENKEL-ECOLAB JOINT VENTURE

The company operates institutional and industrial cleaning and sanitizing
businesses in Europe through its 50 percent economic interest in the Henkel-
Ecolab joint venture. The company includes the operations of the Henkel-Ecolab
joint venture in its financial statements using the equity method of accounting.
The company's equity in earnings of the joint venture, including royalty income
and after deduction of intangible amortization, was $13 million in 1996, a 69
percent increase over weak results of $8 million in 1995. The improvement
reflected the benefits from a number of cost control programs which were put
into effect in 1996. Operating results at the joint venture also reflected lower
interest expense and lower overall income tax rates. Joint venture sales,
although not consolidated in Ecolab's financial statements, increased 4 percent
for 1996 when measured in Deutsche marks. When measured in U.S. dollars, joint
venture sales were negatively affected by the strengthening U.S. dollar, and
totaled $905 million, just below the $909 million of sales recorded for 1995.
Sales benefitted from new product introductions, but continued to reflect
challenging conditions in Europe's food service and hospitality markets,
particularly in the major markets in Germany, France and Italy.

1995 COMPARED WITH 1994

The company's equity in earnings of the Henkel-Ecolab joint venture was $8
million, a substantial decrease from the equity in earnings of $11 million in
1994. These disappointing results reflected higher raw material costs, higher
overall tax rates and investments made by new management in personnel,
organizational development and financial and operating systems. Financial
results were also unfavorably affected by weak conditions in the hospitality
industry in the joint venture's key market of Germany. Joint venture revenues
increased 3 percent for 1995 when measured in Deutsche marks. When translated
into U.S. dollars, joint venture sales benefitted from a weaker U.S. dollar and
increased 17 percent to $909 million from revenues of $777 million in 1994.

CORPORATE

Corporate operating expense was $3 million in 1996, $4 million in 1995 and $12
million in 1994. Corporate operating expense includes overhead costs directly
related to the joint venture. In addition, expense in 1994 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 1996 was $14 million and increased 25 percent over net
interest expense of $12 in 1995. This increase was due to higher debt levels
during 1996, particularly during the first half of the year, reflecting cash
used during 1995 for the stock purchase self-tender offer and for business
acquisitions during late 1995 and during 1996.

  Net interest expense for 1995 decreased 11 percent 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.

  The company's annual effective income tax rate for 1996 was 41.4 percent,
compared to 1995's effective income tax rate of 39.5 percent. This increase in
the effective income tax rate was primarily due to a higher overall effective
rate on earnings of International operations and to the effects of business
acquisitions. International's effective income tax rate varies from year-to-year
with the pre-tax income mix of the various countries in which the company
operates and savings related to the availability of one-time tax strategies.

  The annual effective income tax rate of 39.5 percent in 1995 decreased from
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.

  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 and $15 million in 1994. 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 1996. The company's debt was rated within the "A"
categories by the major rating agencies during 1996. Significant changes to the
company's balance sheet included the following:

- - The company's balance sheet at December 31, 1996, reflected the acquisitions
of Huntington Laboratories and the Monarch operations of H.B. Fuller. The
increase in other noncurrent assets from year-end 1995 was principally due to
these acquisitions.

- - During 1996, total debt increased to $176 million from $161 million at year-
end 1995 and $147 million at year-end 1994. In January 1996, the company issued
$75 million of 7.19 percent, 10-year term senior notes to a group of insurance
companies. Proceeds from the debt were used to reduce short-term borrowings and
for general corporate purposes, including the Huntington and Monarch
acquisitions.

  At December 31, 1996, the ratio of total debt to capitalization was 25
percent, compared with 26 percent at year-end 1995 and 24 percent at year-end
1994. In addition to the level of debt, the total debt to capitalization ratio
at year-end 1995 reflected a decrease in shareholders' equity due to the
purchase of common stock under the self-tender offer.

FINANCIAL DISCUSSION

  During 1996, the company entered into arrangements to enhance its future
financial flexibility in funding general business needs. In September 1996, the
company amended and restated its Multicurrency Credit Agreement, increasing the
credit available from $150 million to $225 million and extending the term three
years to September 2001. Also, in October 1996, the company filed a shelf
registration with the Securities and Exchange Commission for the issuance of up
to $200 million of debt securities. The company has no immediate plans to issue
debt under the registration.

- - Working capital was $108 million at December 31, 1996, compared with $48
million at year-end 1995 and $148 million at year-end 1994. The increase in
working capital during 1996 included an increase in cash and cash equivalents
and a decrease in short-term debt. The levels of cash and cash equivalents and
short-term debt at year-end 1995 were affected by the company's stock purchase
self-tender offer in mid-1995. Working capital levels at year-end 1994 included
unusually high levels of cash and cash equivalents.

- - 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 was $254 million for 1996 and
increased significantly from cash provided by continuing operating activities of
$163 million in 1995 and $154 million in 1994. Strong earnings, additional
operating cash flows from businesses acquired and favorable timing of payments
were significant factors in this cash flow improvement. 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 in 1995 and 1994 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 $112 million in 1996, $110
million in 1995 and $88 million in 1994. World-wide additions of merchandising
equipment, primarily cleaning and sanitizing product dispensers, accounted for
approximately 70 percent of each year's capital expenditures. The company has
expanded its manufacturing facilities throughout the world in order to meet
sales requirements more efficiently. During 1996, new manufacturing facilities
were opened in Hebron, Ohio, and in Costa Rica and Mexico. The company also
purchased a new manufacturing facility in California, expanded its facilities in
Texas, Korea and South Africa and added plants in Indiana and North Carolina
through the Huntington and Monarch acquisitions.

  Cash used for financing activities reflected the issuance of $75 million of
7.19 percent senior notes. Proceeds from the debt and strong operating cash
flows were used to reduce short-term debt and fund the scheduled repayment
related to the company's 9.68 percent senior notes and repayment of indebtedness
assumed with the Huntington acquisition.

  In 1996, the company increased its annual dividend rate
for the fifth consecutive year. The company has paid dividends on its common
stock for 60 consecutive years. Cash dividends declared per share of common
stock, by quarter, for each of the last three years were as follows:


                      First      Second       Third         Fourth
                    Quarter     Quarter     Quarter        Quarter        Year
- -------------------------------------------------------------------------------
    1996             $0.14       $0.14       $0.14          $0.16        $0.58
    1995              0.125       0.125       0.125          0.14         0.515
    1994              0.11        0.11        0.11           0.125        0.455
- -------------------------------------------------------------------------------

LIQUIDITY

The company maintains a $225 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 and a $200 million shelf registration as alternative sources 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 1997 requirements for growth, possible
acquisitions, new program investments, scheduled debt repayments and dividend
payments.

ECOLAB 1996 ANNUAL REPORT              34

<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.

CASH AND CASH EQUIVALENTS

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

INVENTORY VALUATIONS

Inventories are valued at the lower of cost or market. Domestic chemical
inventory costs are determined on a last-in, first-out (lifo) basis. Lifo
inventories represented 44 percent, 38 percent and 38 percent of consolidated
inventories at year-end 1996, 1995 and 1994, respectively. All other inventory
costs are determined on a first-in, first-out (fifo) basis. 

PROPERTY, PLANT AND EQUIPMENT 

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

INTANGIBLE ASSETS

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

LONG-LIVED ASSETS 

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

NET INCOME PER SHARE

Net income per common share amounts are computed by dividing net income by the
weighted average number of common shares outstanding.

  Fully diluted per share amounts are computed as above and assume exercise of
dilutive stock options.

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

  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 debt and for business acquisitions and other general corporate
purposes.

  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.

  In September 1996, the company amended and restated its Multicurrency Credit
Agreement, increasing the credit available to $225 million and extending the
term three years to September 2001. The terms of the new agreement are generally
similar to the previous $150 million credit facility. The company may borrow
varying amounts from time to time on a revolving credit basis, with loans
denominated in G-7 currencies or certain other currencies, if available. The
company has the option of borrowing based on various short-term interest rates.
No amounts were outstanding under the agreement at year-end 1996. The agreement
includes a covenant regarding the ratio of total debt to capitalization.

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

  As of December 31, the weighted average interest rate on notes payable was 5.1
percent for 1996, 6.3 percent for 1995 and 5.3 percent for 1994.

  As of December 31, 1996, the aggregate annual maturities of long-term debt for
the next five years were: 1997 - $15,276,000; 1998 - $15,222,000; 1999 -
$15,222,000; 2000 - $15,182,000 and 2001 - $14,988,000.

  Interest expense was $19,084,000 in 1996, $15,857,000 in 1995 and $16,213,000
in 1994. Total interest paid was $16,897,000 in 1996, $16,170,000 in 1995 and
$16,402,000 in 1994.

  Other noncurrent liabilities included income taxes payable of $100 million at
December 31, 1996, $96 million at December 31, 1995 and $94 million at December
31, 1994. Income taxes payable reflected a reduction in U.S. federal income tax
payments during 1995 and prior years, as a result of tax losses on the
disposition of a discontinued business in 1992.

4. FINANCIAL INSTRUMENTS

FOREIGN CURRENCY INSTRUMENTS

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

  The company enters into foreign currency forward 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 $115 million
at December 31, 1996, $125 million at December 31, 1995, and $110 million at
December 31, 1994. The unrealized gains on these contracts were not significant.

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

BUSINESSES ACQUIRED

In February 1996, the company acquired Huntington Laboratories, Inc. of
Huntington, Indiana. Huntington is a supplier of sanitizing and infection-
control products for the U.S. healthcare market and a supplier of gym floor
finishes. Huntington has become part of the company's Professional Products
Division (formerly the Janitorial Division), complementing the division's
existing product lines. Included in the purchase was Huntington's QUATS-
Surfactants disinfectant business which did not fit Ecolab's business strategies
and, therefore, was sold in July 1996. Huntington's Gam-Med business was also
sold in early 1997. Annual sales of the core Huntington operations, which the
company retained, were approximately $50 million. Ecolab's purchase price for
Huntington included cash consideration and the assumption of existing
indebtedness which the company repaid concurrent with the consummation of the
stock purchase transaction.

  In August 1996, the company acquired the Monarch division of H.B. Fuller
Company of Saint Paul, Minnesota. Monarch is a provider of cleaning and
sanitizing products and services to the food processing and farm markets in the
United States and Canada. Monarch had annual sales of approximately $30 million
and has become part of the company's Food and Beverage Division.

  These acquisitions have been accounted for as purchases and, accordingly, the
results of their operations have been included in the financial statements of
the company from the dates of acquisition.

KAY MERGER

In December 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.

5. BUSINESS ACQUISITIONS (continued)

  In connection with the merger, $8.0 million of merger costs and expenses ($6.9
million after-tax, or $0.10 per common 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 common 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
common share amounts for 1994, which reflect the elimination of the nonrecurring
merger costs and expenses and pro forma adjustments to present income taxes on
the basis on which they are being reported subsequent to the merger.

     Cash paid for income taxes was $71,963,000 in 1996, $55,214,000 in 1995 and
$34,686,000 in 1994. 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 and
$15 million in 1994. 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, 1996, undistributed earnings of international
subsidiaries and the Henkel-Ecolab joint venture of approximately $60 million
and $45 million, respectively, were considered to have been reinvested
indefinitely and, accordingly, the company has not provided U.S. income taxes on
such earnings. If those earnings were remitted to the company, applicable income
taxes would be offset substantially by available foreign tax credits.

8. RETIREMENT PLANS

PENSION PLANS

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

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

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

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

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

   (millions,  increase (decrease))             1996         1995         1994

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

    The adjustment required to recognize a minimum liability as of year-end 1994
has been included in the company's noncurrent liability for postretirement
healthcare and pension benefits with an equal amount included in the
Consolidated Balance Sheet as an intangible asset.

    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 $10 million at
December 31, 1996, and the annual expense for these plans was approximately 
$2 million in each of the years 1996, 1995 and 1994.

POSTRETIREMENT HEALTH CARE BENEFITS

     The company provides postretirement health care benefits to substantially
all U.S. employees. The plan is contributory based on years of service and
family status, with retiree contributions adjusted annually.
Employees outside the U.S. are generally covered under government-sponsored
programs and the cost for providing benefits under company plans was not
significant.

Postretirement health care benefit expense was:

</TABLE>
 
    As of December 31, the discount rate for the postretirement health care
benefits plan was 7.75 percent for 1996, 7.50 percent for 1995 and 8.25 percent
for 1994. The expected long-term rate of return on plan assets was changed to
9.0 percent at year-end 1996 from 6.0 percent in 1995 and 1994. The changes in
the discount rate and the expected rate of return on plan assets did not have a
significant effect on the expense or obligation of the plan. Plan assets consist
primarily of equity and fixed income securities.

    For measurement purposes, 10.5 percent (for pre-age 65 retirees) and 8.3 
percent (for post-age 65 retirees) annual rates of increase in the per capita 
cost of covered health care were assumed for 1997. The rates were assumed to 
decrease gradually to 6.5 percent and 5.5 percent, respectively, at 2001 and 
remain at that level thereafter. Health care costs which are eligible for 
subsidy by the company are limited to a 4 percent annual increase beginning 
in 1996 for most employees. An increase in the assumed health care cost trend 
rate by one percentage point in each year would increase the accumulated 
postretirement benefit obligation as of year-end 1996 by approximately $5 
million and 1996 expense by approximately $0.4 million. 

SAVINGS PLAN

The company provides a 401(k) savings plan for substantially all U.S. employees.
Employee contributions of up to 6 percent of eligible compensation are matched
50 percent by the company. The company's contribution is invested in Ecolab
common stock and amounted to $6,622,000 in 1996, $5,919,000 in 1995 and
$5,156,000 in 1994.


9. STOCK INCENTIVE AND OPTION PLANS

The company's stock incentive and option plans provide for grants of stock
options and stock awards. Common shares available for grant as of December 31
were 420,048 for 1996, 1,124,768 for 1995 and 2,042,606 for 1994.

    Options may be granted to purchase shares of the company's stock at not
less than fair market value at the date of grant. Options generally become
exercisable over periods of up to four years from date of grant and expire
within 10 years from date of grant. Stock option transactions were:

         Stock options outstanding at December 31, 1996, had a range in 
exercise prices of $11.38 to $37.44 and an average remaining contractual life 
of 6.5 years. Approximately one-third of the options outstanding had an 
exercise price of less than $20.00 and were generally exercisable. 
Approximately one-half of the options outstanding had an exercise price of 
$20.00 to $30.00. The weighted-average remaining contractual life for each of 
these groups of options was four years and eight years, respectively.

    Stock awards are generally 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

9. STOCK INCENTIVE AND
OPTION PLANS  (CONTINUED)

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

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

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

    The pro forma information above only includes stock options granted in 1995
and 1996. Compensation expense under the fair value-based method of accounting
will increase over the next few years as additional stock option grants are
considered.

    The weighted-average grant-date fair value of options granted was $8.30 
per option for 1996 and $7.83 per option for 1995. The weighted-average 
grant-date fair value of options was determined by using the fair value of 
each option grant on the date of grant, utilizing the Black-Scholes 
option-pricing model and the following key assumptions:

10. SHAREHOLDERS' EQUITY

Authorized common stock, par value $1.00 per share, was 100 million shares in 
1996, 1995 and 1994. Treasury stock is stated at cost. Dividends declared per 
share of common stock were $0.58 for 1996, $0.515 for 1995 and $0.455 for 
1994.

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

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

   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 reacquired 577,300 shares of its common stock in 1996 and
364,000 shares in 1994 for this program through open and private market
purchases. The 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 shares then outstanding) 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. During 1996, the company purchased 52,900 shares under
this program and the company may purchase approximately 2.4 million additional
shares from time to time through open market and privately negotiated
transactions to complete the remaining portion of a six million share repurchase
program.

11. RENTALS AND LEASES

The company leases sales and administrative office facilities,
distribution center facilities, automobiles and computers and other equipment
under operating leases. Rental expense under all operating leases was
$35,071,000 in 1996, $32,292,000 in 1995 and $29,129,000 in 1994. As of December
31, 1996, future minimum payments under operating leases with noncancelable
terms in excess of one year were:

12. RESEARCH EXPENDITURES

Research expenditures which related to the development of new products and
processes, including significant improvements and refinements to existing
products, were $28,676,000 in 1996, $28,031,000 in 1995 and $27,615,000 in 1994.

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 included. 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

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, 1996, 1995 and 1994, 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, 1996, 1995 and 1994, and the consolidated results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles.

    Pro forma results 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.
