                                       PART I

Part I is included in the Tennant Company 1997 Annual Report to Shareholders 
(to the extent specific pages are referred to on the Cross Reference Sheet) 
and is incorporated in this Form 10-K Annual Report by reference, except Item 
3 -"Legal Proceedings," of which there were no material legal proceedings 
pending, and Item 4 - "Submission of Matters to a Vote of Security Holders" 
during the fourth quarter, of which there were none.

GENERAL DEVELOPMENT OF BUSINESS

Tennant Company, a Minnesota corporation incorporated in 1909, is a 
Minneapolis-based company that specializes in the design, manufacture, and 
sale of non-residential floor maintenance equipment and related products. On 
February 1, 1994, the Company acquired the business and assets of Castex 
Industries, Inc., a privately owned manufacturer of commercial floor 
maintenance equipment. 

INDUSTRY SEGMENTS, FOREIGN AND DOMESTIC OPERATIONS, AND EXPORT SALES

The Company, as described under "General Development of Business," has one 
business segment. The Company sells its products domestically and 
internationally. Appropriate financial information is provided in the 
Company's 1997 Annual Report to Shareholders, page 24, footnote 2. Nearly all 
of the Company's foreign investment in assets reside within Australia, 
Canada, Japan, Spain, The Netherlands, the United Kingdom, France, and 
Germany. While subject to increases or decreases in value over time due to 
foreign exchange rate movements, these investments are considered to be of 
low business risk.

PRINCIPAL PRODUCTS, MARKETS, AND DISTRIBUTION

Products consisting mainly of motorized cleaning equipment and related 
products, including floor cleaning and preservation products, are sold 
through a direct sales organization and independent distributors in North 
America, primarily through a direct sales organization in Australia, France, 
Spain, The Netherlands, Germany, and the United Kingdom, and through 
independent distributors in more than 40 foreign countries. Additional 
information pertaining to products and marketing methods is included in the 
1997 Annual Report to Shareholders, pages 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13.

RAW MATERIALS AND PURCHASED COMPONENTS

The Company has not experienced any significant or unusual problems in the 
purchase of raw materials or other product components and is not 
disproportionately dependent upon any single source or supply.  The Company 
has some sole-source vendors for certain components, primarily for automotive 
and plastic parts.  A disruption in supply from such vendors may cause a 
short-term disruption in the Company's operations.  However, the Company 
believes that it can find alternate sources in the event there is a 
disruption in supply from such vendors.

PATENTS AND TRADEMARKS

The Company applies for and is granted United States and foreign patents and 
trademarks in the ordinary course of business, no one of which is of material 
importance in relation to the business as a whole.

SEASONALITY

Although the Company's business is not seasonal in the traditional sense, 
revenues and earnings tend to concentrate in the fourth quarter of each year 
reflecting the tendency of customers to increase capital spending during such 
quarter, and the Company's efforts to close orders and reduce order backlogs.

WORKING CAPITAL PRACTICES

The Company's working capital practices are described in the 1997 Annual 
Report to Shareholders, Management's Financial Discussion and Analysis, 
Financial Position section on pages 15, 16 and 17.

MAJOR CUSTOMERS

The Company sells its products to a wide variety of customers, no one of 
which is of material importance in relation to the business as a whole.

BACKLOG

The Company routinely fills orders within 30 days on the average. 
Consequently, order backlogs are not indicative of future sales levels.

COMPETITIVE POSITION

While there is no industry association or industry data, the Company 
believes, through its own market research, that it is a world-leading 
manufacturer of floor maintenance equipment. Active competition exists in 
most geographic areas; however, it tends to originate from different sources 
in each area, and the Company's market share is believed to exceed that of 
the leading competitor in many areas. The Company competes primarily on the 
basis of offering a broad line of high-quality, innovative products supported 
by an extensive sales/service network in major markets.

PRODUCT RESEARCH AND DEVELOPMENT

The Company regularly commits what is believed to be an above-average amount 
of resources to product research and development. These amounts are reported 
on the Company's 1997 Annual Report to Shareholders, page 24, footnote 3. A 
description of product development is included in the 1997 Annual Report to 
Shareholders on pages 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13.

ENVIRONMENTAL PROTECTION

Compliance with federal, state and local provisions regulating the discharge 
of materials into the environment, or otherwise relating to the protection of 
the environment, has not had, and is not expected to have, a material effect 
upon the Company's capital expenditures, earnings or competitive position.

EMPLOYMENT

Year-end employment is reported in the 1997 Annual Report to Shareholders on 
page 30.

         21.1      Subsidiaries of the Registrant                     

                   Tennant Company has the
                   following subsidiaries:

                   Tennant Holding B.V. is 
                   a wholly owned 
                   subsidiary organized 
                   under the laws of the 
                   Netherlands in 1991. A 
                   legal reorganization 
                   occurred in 1991 whereby 
                   Tennant N.V. became a 
                   participating interest 
                   of Tennant Holding B.V. 
                   Tennant N.V. had 
                   previously been a wholly 
                   owned subsidiary 
                   organized under the laws 
                   of the Netherlands in 
                   1970. Tennant 
                   Maintenance Systems, 
                   Limited, was a wholly 
                   owned subsidiary, 
                   organized under the laws 
                   of the United Kingdom 
                   until October 29, 1992, 
                   at which time Tennant 
                   Holding B.V. acquired 
                   100% of its stock from 
                   Tennant Company. 
                   The name was formally
                   changed to Tennant UK
                   Limited on or about 
                   October 16, 1996.  Castex
                   Incorporated, is a wholly 
                   owned subsidiary organized
                   under the laws of the state 
                   of Michigan. The results of 
                   these operations have 
                   been consolidated into 
                   the financial 
                   statements, as indicated

TO OUR SHAREHOLDERS


   1997 was a fine year at Tennant: sales up 8% to $372 million, earnings per 
diluted share rose 15% to $2.41, and operating margin increased to 9.7% from 
9.2% the prior year. All this occurred in the face of an exceptionally strong 
dollar, which reduced translated sales by $8.4 million and net earnings by an 
estimated $1.8 million, or 18 cents per share. We obviously were helped a 
great deal by very good economic conditions in the U.S., improving conditions 
in Europe, and no big problems in the rest of the world. However, the most 
satisfying part of 1997's results was that they reflected the significant 
changes going on at Tennant.

MEETING THE PREEMINENCE 2000 CHALLENGES

   Tennant is both an old company--started in 1870--and a new, revitalized 
company--starting in 1992. At that time, we had come through 10 tough years 
for U.S. manufacturers. We had a respectable record, had improved our product 
quality, invested in new products and information technology, kept the 
balance sheet strong, and raised the dividend every year. But we had not 
grown as much as we would have liked, nor had we reached our full 
profit-making potential. 

   In 1992, we set goals for the year 2000, called "Preeminence 2000" or 
"P-2000" for short, aimed at greater customer satisfaction, stronger growth, 
and higher profitability. P-2000 led us to challenge each area of our 
business and take action to improve. The results have been falling in place 
each year and are very satisfying:

- -    For industrial equipment, our core business, we dramatically increased the
     pace of new product development, bringing great value to the marketplace
     and putting relentless pressure on our competitors. These new and updated
     products have been outstanding successes, giving more features and benefits
     at lower prices, and so far sales have exceeded our forecasts. In 1998, we
     will release four new products: a record for us and a near impossible pace
     for our competition.

- -    For commercial equipment, our P-2000 challenge led to the very successful
     Castex acquisition in early 1994, followed by the smaller acquisition of
     Eagle in late 1994. Although these companies were solid contributors from
     the start, the first couple of years were devoted to integration issues
     that are now behind us. More recently, we have been able to focus on
     commercial equipment growth in large corporate accounts and international
     markets, with very good results.

- -    Floor coatings, which now represent about 6% of our total revenues, also
     went through a transformation as part of P-2000. We got out of the
     contracting business and established solid partner relationships with
     independent contractors throughout the U.S., Mexico, and Canada. Our
     overall floor coatings growth since 1992 has been 9% compounded, and our
     progress in the second half of 1997 gives us encouragement that 1998 will
     be an excellent year for this profitable piece of our company.

   What is most important about all this is that it was not happenstance. It 
was the result of a determination to evolve from a good company to a great 
one by:

- -    World-class customer satisfaction, resulting from exciting new products,
     outstanding customer service, and careful monitoring of our customer
     service processes.

- -    Energized, well-trained and well-supported employees at all levels. After
     all, how can

We note with great sadness the passing of George Pennock, grandson of our
founder and former President and Chairman of Tennant.  During his 43-year career
at Tennant, George Pennock embedded in our culture a great regard for employees,
sound financial policies, and a spirit of Internationalism which are core values
for us today.

We will all miss his wit, wisdom, and business acumen.

     customers be happy if our employees are not? Along that line, we were very
     honored to be on FORTUNE Magazine's list of the "100 Best Companies in
     America to Work For."

- -    Strategic use of information technology based on a companywide "enterprise"
     computer system (SAP's R/3). We now are starting the fourth year of this
     five-year project. By year-end, a number of significant parts of this
     comprehensive system will be in full, day-to-day use.

- -    Outstanding financial strength. Our balance sheet is strong; our ratios are
     excellent. In 1997, we raised the dividend for the 26th consecutive year,
     returned $21 million to shareholders in the form of dividends and stock
     repurchases, funded $17 million of capital equipment purchases, and
     increased cash on hand by 60% to $16 million.

ORGANIZATIONAL CHANGE

   A major project in the past few years has been developing greater bench 
strength in top management. We are a specialized company with a very strong 
position in various nonresidential floor cleaning niches. Because our 
greatest opportunities lie in leveraging our products and markets, we needed 
to focus on broadening and deepening our management base. 1996 was consumed 
with a market and organizational study. This resulted in some reorganization 
in the fall of 1996. The distraction of this change is behind us, and the new 
teams are working well together. 1997 results reflect this, and 1998 should 
benefit even further.

CAPITALIZING ON THE OPPORTUNITIES OF 1998

   In short, 1997 was a very satisfying year at Tennant. Economic conditions 
were good and specific measures we had taken in the previous few years 
positioned us to "make hay while the sun shines." 

   Will the sun be shining in 1998? We believe it will in North America. Our 
products, people, and processes, combined with continued although somewhat 
more modest economic growth, will keep the momentum going. In Europe, we had 
an excellent year in 1997. The many organizational and process changes made 
in 1995 and 1996 settled down and now are working to our advantage. We 
believe European economic conditions in 1998 are improving, and we are ready 
to benefit from them.

   Asia is the cloud on the horizon. Only 5% of our total revenues came from 
this region in 1997. In the future, we expect stronger growth because we 
recently increased our long-term commitment there by opening an office and 
warehouse in Singapore, and established partnerships to promote our 
commercial floor care products through common distribution. Some areas of our 
business, especially industrial equipment, will have a tougher time in 1998 
in such countries as Korea, Malaysia, and Thailand. However, our overall 
strategy is very straightforward:

- -    Support our distribution in every way possible.

- -    Continue to build better products and processes for this vital part of the
     world.

   This strategy has served us well in Mexico, where we now are stronger than 
ever. It will serve us well in Asia, which will be a great growth market for 
us as we enter the 21st century.

   We finished 1997 with somewhat higher backlogs and strong order growth in 
key markets. With this in mind, and the consensus view that the Asian 
financial crisis will have only a modest effect on the world's major 
economies, we believe Tennant is positioned to achieve another year of record 
financial performance, creating above-average value for our shareholders.

"FOR MANY YEARS, NORTH AMERICAN MARKETS WERE CONSIDERED 'MATURE.' THIS WAS TRUE
AS LONG AS WE CONCENTRATED ON PRODUCTS RATHER THAN CUSTOMERS. NOW THAT WE ARE
FOCUSING MORE ON CUSTOMERS, WE BELIEVE THE OPPORTUNITIES ARE TREMENDOUS."

REINVIGORATING OUR APPROACH TO A KEY MARKET

   Tennant gained leadership in North America by developing a broad line of 
products known for their quality, then marketing them through a strong direct 
sales force and distributor network. Several years ago, we began to focus on 
customer partnerships. While this represented progress, we knew we needed to 
stretch further.

   More recently, we decided the best way to reinvigorate our growth would be 
to eliminate the internal barriers between industrial, commercial, and floor 
coatings sales and service, which were operating independently of each other, 
in order to take advantage of cross-selling opportunities.

   The Industrial Markets and Commercial Markets divisions continue to 
directly serve their traditional customer base. However, we are testing a 
program that brings commercial distributors and industrial direct sales and 
service forces together in order to better market our full product line to 
both customer groups. In addition, we have established two divisions, Global 
Markets and Customer Solutions, that market our products and services to 
specific groups of customers with unique needs not previously met by our 
product-line focused divisions (e.g., a customer that wants products from 
more than one of our lines plus support services such as training or advice 
on cleaning methodologies).

   By more integration of our products, services, and channels, Tennant will 
be able to capitalize on many more opportunities than previously. This is 
being supported by our investment in technology. Soon we will be able to 
capture more information on our customers, analyze it more effectively, and 
share it across the company. Our use of technology will enhance our advantage 
by allowing us to serve customers faster. This is critical as customers

INDUSTRIAL MARKET

   Tennant is the acknowledged leader in the industrial market, both 
domestically and internationally. In North America, Tennant holds more than a 
50% share of the cleaning equipment market which is about three times that of 
our nearest competitor.

INDUSTRIAL MARKET TRENDS

   A number of industry trends are returning this to a growth market for us:

- -    A new growth area for Tennant is in the urban downtown outdoor market.
     These commercial centers recognize that to attract people and maintain
     business they need to provide a clean and safe environment in which to
     work, shop and play. Thousands of quasi-government associations across the
     country are looking for partners to provide them with the cleaning
     solutions they need to meet their vision of cleaner and safer urban
     communities. Tennant is well positioned to be that partner with its
     extensive product line supported by its nationwide sales and service
     network.

- -    Businesses want cleaner and safer indoor and outdoor environments as well.
     Reasons include a focus on quality, which starts with clean workplaces, and
     the Environmental Protection Agency's increased environmental regulations
     which are requiring many businesses to comply with stronger standards for
     cleanliness.

- -    Many businesses are outsourcing operational activities. In our case, this
     is increasing the number of contract cleaners who handle facility
     maintenance--and are interested in our products.

- -    Businesses of all kinds are reducing the number of vendors they use. In
     general, they are looking for suppliers with a broader product offering
     and, in many cases, a global reach to handle their needs.

- -    In North America, demand is moving from sweeping (picking up debris only)
     to sweeping and scrubbing (actually cleaning the surface after it has been
     swept). This is reflected in Tennant's sales. Twenty years ago scrubbers
     generated less than 20% of our industrial equipment sales in this market.
     By 1997, this has increased to more than 50%.

- -    The demand is increasing for machines that are easier to maintain and
     operate so people at all skill levels can use them.

INDUSTRIAL MARKET (CONT'D)

OFFER WIDEST LINE OF INDUSTRIAL PRODUCTS

   These machines clean areas with vehicle or heavy foot traffic. They come 
in walk-behind and rider units with prices that range from $7,500 to $90,000. 
Tennant offers three types of products, all of which carry the strongest 
warranties in the industry:

- -    SWEEPERS remove wet or dry debris, and control dust during this process.

- -    SCRUBBERS lay down cleaning solution, scrub the surface, then remove the
     dirty solution--all in one pass.

- -    COMBINATION SWEEPER/SCRUBBERS perform both functions at the same time, also
     in one pass.

   Industrial products for North America are developed and manufactured in 
our Minneapolis, Minnesota, facility, which is ISO 9001 quality certified. 
(Products are also exported from this facility to our various international 
markets.)

   We devote an industry-leading amount to product engineering. Through the 
use of process improvement and technology, we have been able to cut the 
product development cycle in half in recent years. This has allowed us to 
introduce no fewer than two and as many as four new or significantly updated 
products each year. The end result is quite significant--nearly 90% of our 
1997 machine sales were generated by products introduced in the last five 
years.

   New product introductions this year centered on smaller machines to reach 
markets where we had not been traditionally as strong.

   In 1998, we will continue our aggressive product introduction program.

UNIQUE DIRECT SALES/SERVICE FORCE

   For the most part, our competitors use distributors to sell and service 
their industrial products. Tennant, on the other hand, sells exclusively 
through a direct sales and service network in North America. This gives us a 
significant competitive edge in the sale of larger industrial equipment.

OUTPERFORMING THE INDUSTRIAL MARKET

   All of these strategies, backed by a good economy, allowed Tennant to 
increase its orders of industrial machines in North America by 18% in 1997. 
This indicates there are many opportunities for growth in this market--and 
Tennant as the industry leader is capitalizing on them.

COMMERCIAL MARKET 

   Tennant holds an estimated 15% share of the North American commercial 
cleaning equipment market, with most of that through its Castex Inc. 
subsidiary. Since joining Tennant in 1994, Castex has advanced to being among 
the top three companies in the market. (On a combined basis, we estimate that 
the top three competitors hold somewhat more than 50% of the total market.)   

   A number of trends are driving growth in this market:

- -    Businesses and institutions that directly service the public on their
     premises are being driven by a consumer preference for clean, safe
     facilities; and employers are focusing on quality and productivity
     improvement which begins with a clean workplace.

- -    There also are two trends specific to the commercial market:

     -    The service sector--the primary purchaser of commercial equipment--is
          the fastest growing part of the economy.

     -    Businesses want to reduce the potential liability of wet or dirty
          public places.

   The commercial floor maintenance industry is experiencing consolidation, 
which bodes well for Tennant:

- -    Smaller manufacturers are being acquired by larger firms or closing their
     doors. This has presented Tennant with acquisition opportunities in recent
     years, and it has raised entry barriers as the size of competitors has
     increased.

- -    Distributors--the main channel for selling and servicing commercial
     equipment--are undergoing consolidation. This means the ones that remain
     will be stronger and will

want to work with larger, more stable firms such as Castex.

EXPANDING BROAD PRODUCT LINE

   We offer a complete line of commercial maintenance equipment:

- -    SWEEPERS AND VACUUMS remove debris or water from virtually any surface.

- -    AUTOMATIC SCRUBBERS clean grease and grime from hard surfaces, such as
     floors with tile and grout. These machines remove virtually all of the
     cleaning solution they apply to the floor, which is critical for avoiding
     slip-and-fall injuries. They also are easy to operate and maneuver in tight
     spaces.

- -    CARPET EXTRACTORS apply a cleaning solution, scrub the carpet, then remove
     the solution along with any dirt and grime.

- -    BURNISHERS AND FLOOR MACHINES give scrubbed floors a shiny, high-gloss
     appearance.

   Castex products, which range in price from $300 to $7,000, are used by 
hospitals, schools, shopping malls--any area that has heavy foot traffic. 
These products are developed and manufactured in our Holland, Michigan, 
facility.

   After being acquired by Tennant in 1994, Castex's efforts were focused on 
a successful integration of product lines and distribution. As a result, 
engineering efforts concentrated mainly on product maintenance and 
refinement. This has changed recently and will result in a more agressive 
product introduction schedule in 1998 and beyond, which will help us gain 
market share.

FLOOR COATINGS MARKET


   Tennant holds an estimated 15% share of the North American market for 
industrial floor coatings, sealers and resurfacers. A competitive edge for 
Tennant comes from the fact that we offer our coatings as a complementary 
product to industrial floor cleaning equipment and, in fact, sell through the 
same direct sales force.

FLOOR COATINGS MARKET TRENDS

   There is a strong interest in coatings because they protect concrete and 
wood floors from chemicals and wear, they make floors easier to clean, and 
they create a working environment that improves employee morale and a 
company's image.

DEVELOPING LEADING-EDGE PRODUCTS AND SERVICES

Tennant offers a broad product range:

- -    DURABLE COATINGS for main traffic aisles and loading docks.

- -    CHEMICAL-RESISTANT COATINGS for floors exposed to corrosive chemicals.

- -    EPOXY RESURFACERS for damaged floors that need to have their smooth surface
     restored.

- -    ENVIRONMENTALLY SAFE COATINGS for odor-sensitive applications, such as food
     processing facilities. Our unique Eco-Coatings-TM- line combines high
     durability with little or no solvents.

- -    ECO-PREP-TM- PROCESS for use by Tennant's authorized contractors to prepare
     a floor for its new coating. Eco-Prep-TM- machines remove the old coatings
     quickly and without using solvents. No one else offers as effective an
     approach.

   We develop the formulas for our coatings and oversee their production, and 
we manufacture the Eco-Prep-TM- machines.

   Our coatings are designed to address the major needs of our customers, 
which include appearance, coating durability and life, ease of application, 
and environmental impact. A primary objective of our product development in 
recent years has been to meet or exceed the increasing government regulations 
for waste control and emissions, even before these regulations go into effect.

FLOOR COATINGS IS A VITAL PART OF TOTAL SOLUTION

   After experiencing a slow start to the year, our sales have been on a 
stronger growth track, and we finished the year with record December 
billings. We believe we can maintain this stronger growth as coatings become 
a more important part in the total solution Tennant offers its customers.

TENNANT IN INTERNATIONAL MARKETS

   Tennant has sold its products internationally since the 1950s. No single 
competitor from the U.S. or any other country has Tennant's broad level of 
international market penetration in floor maintenance equipment.

INTERNATIONAL FLOOR CLEANING TRENDS

   A number of trends that cross country borders are driving the 
international market:

- -    More businesses in various industries are becoming global players and
     therefore have global demands for the products and services they purchase.

- -    Many businesses are turning to contract cleaners--local and multinational
     firms--to handle this non-core operational activity for them. In Europe,
     for example, contract cleaners hold as much as a 50% market share--much
     larger than in North America.

- -    Many businesses--and countries--are interested in cleaner, safer work and
     public places. However, for some it still remains a concept that must be
     "sold" to them rather than seen as a business or social need.

- -    The best-selling industrial products in international markets tend towards
     the smaller sizes because of narrow aisles and other space constraints.
     Scrubbing in many areas is not as common as in Europe or North America
     because the concept of a cleaner, safer environment is in an earlier state
     of development.

HOW TENNANT DIFFERENTIATES ITSELF INTERNATIONALLY

   In addition to our size, Tennant has distinguished itself in a number of 
other ways. One important difference is that nonresidential floor care is our 
ONLY business. This generates just a portion of our competitors' sales, since 
they tend to also be in other businesses either only remotely related to 
floor cleaning or not related at all.

   Tennant has a broad, innovative product line to serve the needs of both 
industrial and commercial settings. We have adjusted these products to 
reflect international needs, such as offering smaller equipment and equipment 
that meets different noise and pollution standards.

   We also directly sell and service our products where the market warrants 
the investment (currently Australia, France, Germany, The Netherlands, Spain 
and the United Kingdom--in addition to North America). This gives us more 
flexibility in meeting customers' needs in these larger markets. Tennant also 
has very strong relationships with distributors in over 45 other countries, 
including Japan. This strength is reflected in the average length of 
distribution contracts. Tennant's agreements tend to be in the range of 10 to 
14 years versus the industry average of 3 to 4 years.

   In the coming years, Tennant will be able to provide an advantage no other 
competitor has: nearly seamless sales and service to multinational companies 
at their various international sites. We are presenting a uniform product and 
service offering to customers around the world. This will help us 
differentiate Tennant from its competitors and expand our global leadership 
position.

"THERE IS NO HOMOGENEOUS 'INTERNATIONAL' MARKET--EACH COUNTRY IS UNIQUE. THEIR

FROM FLOOR CLEANING MACHINES IS DIFFERENT. OUR CHALLENGE IS TO MAKE SURE OUR
SOLUTIONS RELATE TO EACH LOCAL MARKET."

FINANCIAL RESULTS OF OPERATIONS  

   EARNINGS: For 1997, net earnings were $24.2 million, or $2.41 per diluted 
share, up 15% from the prior year. Return on sales was 6.5%, and return on 
beginning shareholders' equity was 18.8%. The reasons for the earnings gain 
were higher sales, and increases in gross margin and other income. A much 
stronger U.S. dollar reduced earnings by an estimated $1.8 million, or 18 
cents per share.

   For 1996, net earnings were $21.0 million, or $2.09 per diluted share, up 
6% from the prior year. Return on sales was 6.1%, and return on beginning 
shareholders' equity was 18.4%. The reasons for the earnings gain were higher 
sales, a relatively low rate of growth for expenses, and an increase in other 
income. A somewhat stronger U.S. dollar reduced earnings by an estimated $0.6 
million, or 6 cents per share.

   For 1998, management is somewhat cautious in its outlook because of the 
financial crisis in Asia. However, the Company's sales to the affected 
countries represented only 5% of total revenue in 1997, and the region's 
problems are expected to have only a modest effect on the world's major 
economies. With this in mind and given the fact that 1997 finished with 
somewhat higher backlogs and continued good order growth in most markets, 
management believes another year of higher sales and earnings is possible.

   SALES: For 1997, net sales of $372 million increased 8% from the prior 
year and backlogs were up $2 million to $13 million. A much stronger U.S. 
dollar reduced full year sales by $8 million.

   North American sales of $276 million were up 11% on robust economic 
conditions and a significant number of new and updated products introduced in 


                                      14

recent years. Sales increases by product line were 12% for industrial 
equipment, 9% for commercial equipment, and 7% for floor coatings.

   International sales of $96 million, representing 26% of consolidated 
revenues, increased only 1% in translated U.S. dollars, but were up 9% in 
local currencies. The strongest local currency increases were in Japan and 
Australia, and several countries in Europe.

   For 1996, net sales of $344 million increased 6% from the prior year and 
backlogs declined by $1 million. A somewhat stronger U.S. dollar reduced full 
year sales by $3 million. North American sales of $249 million were up 6% on 
economic conditions that were weak early in the year, especially in the 
industrial sector, but that improved steadily as the year progressed. Sales 
increases by product line were 8% for commercial equipment, 5% for industrial 
equipment, and 2% for floor coatings. International sales of $95 million for 
1996, representing 28% of consolidated revenues, increased 5% (up 9% in local 
currencies). The strongest sales gains were in Japan, France and Australia.

   PROFIT FROM OPERATIONS: For 1997, profit from operations increased 14% to 
$36.1 million on an 8% sales increase, resulting in an operating margin of 
9.7% versus 9.2% the prior year. Factory capacity use is estimated to have 
been in the 70% range overall with North American facilities at the upper end 
of the range. (Some capacity expansion will likely be required within the 
next several years.)

   The improvement in operating margin was due to an increase in gross margin 
to 42.2% from 41.3% the prior year. The improvement was primarily due to a 
favorable product mix, manufacturing efficiencies on the higher production 
volume, and a relatively low rate of inflation for costs and expenses.

   Selling and administrative expenses, as a percent of sales, increased to 
32.5% from 32.2% the prior year. The increase was primarily due to higher 
incentive compensation resulting from an increased growth rate, stronger 
financial performance, and a significant increase in the market value of the 
Company's common stock.

   For 1996, profit from operations increased 5% to $31.6 million on a 6% 
sales increase, resulting in an operating margin of 9.2% versus 9.3% the 
prior year. Factory capacity use is estimated to have been in the low 70% 
range for the year. The change in operating margin was due to a decline in 
gross margin to 41.3% from 42.9% the prior year. The decline was primarily 
due to a change in the sales mix to lower margin products and market 
segments, operational inefficiencies in Europe, and translation effects of 
the stronger U.S. dollar. Selling and administrative expenses, as a percent 
of sales, declined to 32.2% in 1996 from 33.7% the prior year. The decline 
was primarily due to steps taken to substantially slow the rate of expense 
growth.

   OTHER INCOME AND EXPENSE: For 1997, the Company recorded other income of 
$1,542,000 versus $698,000 in the prior year. The primary reasons for the 
increase were more interest income on a higher level of invested cash and 
less interest expense on a lower level of debt.

   Included in other income is $4.7 million of interest income in 1997. Of 
this amount, $2.4 million is from finance-type leases provided to customers, 
and $1.5 million is from a loan to the Company's Employee Stock Ownership 
Plan (ESOP).

   For 1996, the Company recorded other income of $698,000 versus other 
expense of $747,000 in the prior year. The primary reasons for the change 
were a reduction in the discretionary contribution to the Company's 
charitable foundation, a higher level of interest income, and less interest 
expense.

   For 1998, management anticipates a somewhat higher level of net other 
income than recorded in 1997 due to reductions in foreign currency 
transaction losses and the discretionary contribution to the Company's 
charitable foundation.

   INCOME TAXES: For 1997, the effective tax rate increased to 35.7% 
primarily because pre-tax earnings were up the most in higher taxing 
jurisdictions.

   For 1996, the rate increased to 35.0% from an unusually low 33.2% the 
prior year. (The 1995 rate was affected by tax losses in several tax 
jurisdictions and a relatively high level of tax credits.) 

   For 1998, management anticipates an effective tax rate in the mid-35% 
range.

LIQUIDITY AND CAPITAL RESOURCES

   The Company continues to generate substantial cash flow and was again able 
to strengthen its financial condition in 1997.


                                      15

<PAGE>

   FINANCIAL POSITION: Cash and cash equivalents ended 1997 at $16 million, 
up from $10 million the prior year, and debt was reduced to $23 million, or 
15% of capital, from $26 million, or 17% of capital. Based on current 
operating plans, dividend policy, and stock repurchase authority, management 
expects cash and debt to decline somewhat by the end of 1998.

   Working capital, excluding cash and debt, increased by 2% from the prior 
year-end due to the higher level of business activity. At December 31, 1997, 
the Company held $1.1 million of unsecured trade receivables from 
distributors located in Asia and Latin America. Management believes the 
allowance for doubtful accounts is adequate to cover losses resulting from 
the Asian financial turmoil. Working capital will likely increase in 1998; 
however, the percentage change is expected to again be less than sales growth.

   Property, plant, and equipment, net of accumulated depreciation was about 
flat compared to the prior year-end. Depreciation expense was $16.2 million, 
capital spending net of disposals was $16.4 million. The largest categories 
of capital spending were information technology hardware and software, 
vehicles (cars, trucks and trailers), industrial products financed with 
operating leases for customers, product tooling, factory equipment, and a 
warehouse/distribution center in Michigan that will consolidate several 
leased facilities in the Great Lakes region. Vehicles represent a large 
category of spending because of the use of direct sales and service in key 
industrial markets.

   For 1998, management expects depreciation expense of about $17 million and 
capital spending, net of disposals, of about $20 million. This level of 
capital spending, which is relatively high in a historical sense, reflects 
the Company's continuing commitment to the increasing use of information 
technology to enhance its competitive position and resolve "Year 2000" 
computer systems' issues.

   DIVIDENDS AND COMMON STOCK: Cash dividends of 72 cents per share were up 
4%, the 26th consecutive year of increase. Common diluted shares outstanding 
averaged 10,031,600 in 1997, a decrease from the prior year's 10,075,800. 
Outstanding diluted shares at year-end declined 2% to 9,821,100.

   On May 1, 1997, the Board of Directors authorized the repurchase of 
600,000 shares of Company stock. During 1997, the Company repurchased 329,407 
shares under this authority and 56,033 shares under a previous authority for 
an overall average price of $35.26 per share. On February 26, 1998, the Board 
of Directors canceled the unused authority (approximately 191,000 shares) 
related to the May 1997 authorization and established a new authority to 
repurchase up to 600,000 shares of Company stock.

   IMPACT OF INFLATION: Inflation has not been a significant factor for 
several years. For 1997, it is estimated that product pricing, on average, 
was somewhat above the inflation experienced by the Company for costs and 
expenses. For 1998, management expects that product pricing will be about 
equal to inflation.

   The relatively high inflation of the 1970s and early 1980s continues to be 
reflected in the Company's historical-cost balance sheet in the following 
ways:

- -    Inventories are significantly below current replacement cost because they
     are, for the most part, stated on a last-in, first-out basis. (See "Notes
     to Consolidated Financial Statements," note 1, for amounts involved.)

- -    Property, plant, and equipment is stated at historical cost, which is below
     current replacement value for older assets.

   These shortcomings of historical-cost financial statements are managed by 
establishing return-on-investment objectives based on current values for 
assets. In addition, price indexes are used to estimate real, 
inflation-adjusted sales which allow for more meaningful measurements of 
growth over extended periods of time.

   IMPACT OF CHANGING VALUE OF THE U.S. DOLLAR: Approximately one-third of 
the Company's sales occur outside of the United States directly or through 
independent distributors in over 50 countries. Sales in Australia, Canada, 
Japan, and the European direct-sales countries of Germany, France, Spain, the 
United Kingdom, and The Netherlands are made in their respective currencies. 
Sales in other countries, which are generally to distributors, are made in 
either U.S. dollars or, in Europe, in Dutch guilders.

   In recent years, the world's key currencies have experienced significant 
changes in relative value over short periods of time. The U.S. dollar began 
1997 on a 


                                      16

<PAGE>

strong note and continued to rise in value over the remainder of the year. 
Management estimates the impact of these rate changes by recalculating 
current-year results using prior-year exchange rates. The resulting 
difference in results is an approximation of the effect rate changes have 
under static analysis (i.e., no consideration given to possible reactual 
changes such as adjusted pricing, volume sensitivity to price changes, etc.).

   The Company uses hedging arrangements such as forward-exchange and 
range-forward contracts from time to time to offset short-term changes in 
currency values. At the end of 1997, the Company had outstanding $6 million 
of forward-exchange contracts denominated in Canadian and Australian dollars 
(see "Notes to Financial Statements," note 14). Since these contracts are 
relatively small in value and are treated as hedges of specific balance sheet 
monetary amounts denominated in these currencies, or nearly certain product 
exports to be sold in these currencies, there is only limited potential for 
impact on the Company's future liquidity.

FINANCIAL GOALS AND POLICIES

   The Company's financial mission is to create value for shareholders by 
providing an above-average total return. Goals and policies that support this 
mission are:

- -    Growth - Annual increases of 8% in sales and at least 10% in earnings per
     share over a full economic cycle; measured from cycle peak to peak.

- -    Profitability - Averaging a 20% return on beginning shareholders' equity in
     the growth years of an economic cycle.

- -    Financial Policies - Consistent annual dividend increases and maintenance
     of a sound capital structure with financing debt generally not in excess of
     30% of capitalization.

   Summaries of the Company's financial performance compared with these goals 
are presented in several graphs and tables included in this report.

CHANGES IN LEASING BUSINESS

   For many years, Tennant provided long-term financing to customers. 
Arrangements have been made with General Electric Capital Companies 
(GE Capital) to provide these services beginning January 2, 1998. The Company 
is also arranging for the sale of its existing financing-related portfolio to 
GE Capital. (At December 31, 1997, the portfolio consisted of lease-type 
contracts and financing equipment still owned by Tennant, with a combined net 
book value of $18 million.) A substantial portion of the portfolio is 
expected to be sold within the next several months at net book value plus a 
gross profit on the financed equipment and a portion of future interest, less 
administrative charges and contingency reserves. It is not possible to 
determine the impact of this transaction on full-year 1998 net earnings at 
this time. However, on a year-over-year comparison with 1997, the net gain on 
the sale will be at least partially offset by the absence of lease financing 
income for the remainder of 1998.

YEAR 2000 COMPUTER SYSTEMS' ISSUES

   Several years ago, the Company embarked on a major, long-term effort to 
upgrade its computer systems. For the most part, this involves the 
companywide installation of SAP's R/3 enterprise system, which is fully 
year-2000 compliant. This investment, which has been commented on from time 
to time in public disclosures, was undertaken for strategic reasons such as 
gaining a competitive edge, improving operating efficiency, and reducing 
costs. Management believes this new system will substantially resolve the 
Company's year-2000 date-change issues. While some additional expense 
directly related to year-2000 issues has been and will continue to be 
incurred, the estimated amounts involved are not material.

MANAGEMENT'S REPORT

The Company's management is responsible for the integrity and accuracy of the 
financial statements. Management believes that the financial statements for 
the three years ended December 31, 1997, have been prepared in conformity 
with generally accepted accounting principles appropriate in the 
circumstances. In preparing the financial statements, management makes 
informed judgments and estimates where necessary to reflect the expected 
effects of events and transactions that have not been completed.

In meeting its responsibility for the reliability of the financial 
statements, management relies on a system of internal accounting control. 
This system is designed to provide reasonable assurance that assets are 
safeguarded and transactions are executed in accordance with management's 
authorization and recorded properly to permit the preparation of financial 
statements in accordance with generally accepted accounting principles. The 
design of this system recognizes that errors or irregularities may occur and 
that estimates and judgments are required to assess the relative cost and 
expected benefits of the controls. Management believes that the Company's 
accounting controls provide reasonable assurance that errors or 
irregularities that could be material to the financial statements are 
prevented or would be detected within a timely period.

The Audit Committee of the Board of Directors, which is comprised solely of 
Directors who are not employees of the Company, is responsible for monitoring 
the Company's accounting and reporting practices. The Audit Committee meets 
periodically with management and the independent auditors to discuss internal 
accounting control, auditing, and financial reporting matters.

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

INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders
Tennant Company:

We have audited the accompanying consolidated balance sheets of Tennant 
Company and subsidiaries as of December 31, 1997 and 1996, and the related 
consolidated statements of earnings, shareholders' equity, and cash flows for 
each of the years in the three-year period ended December 31, 1997. These 
consolidated financial statements are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these consolidated 
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 consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of Tennant 
Company and subsidiaries as of December 31, 1997 and 1996, and the results of 
their operations and their cash flows for each of the years in the three-year 
period ended December 31, 1997, in conformity with generally accepted 
accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- ------------------------------------------
(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND OTHER RELATED DATA

CONSOLIDATION. The consolidated financial statements include the accounts of 
Tennant Company and its wholly owned subsidiaries, Castex, Incorporated, and 
Tennant Holding B.V. All material intercompany transactions and balances have 
been eliminated.

TRANSLATION OF NON-U.S. CURRENCY. Foreign currency denominated assets and 
liabilities have been translated to U.S. dollars generally at year-end 
exchange rates, while income and expense items are translated at exchange 
rates prevailing during the year. Gains or losses resulting from translation 
are included as a separate component of shareholders' equity. Transaction 
gains or losses are included in current operations.

USE OF ESTIMATES. The preparation of financial statements in conformity with 
generally accepted accounting principles requires management to make 
estimates and assumptions that affect the reported amounts of assets and 
liabilities and 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 could differ from those estimates.

INVENTORIES. Inventories are valued at the lower of cost (principally on a 
last-in, first-out basis) or market. Inventories would have been higher than 
reported, as is shown below, had they been valued using the first-in, 
first-out method of accounting, which approximates replacement cost.

The composition of inventories at December 31 is as follows:

</TABLE>


PROPERTY, PLANT, AND EQUIPMENT. Property, plant, and equipment is carried at
cost. Expenditures for improvements that add materially to the productive
capacity or extend the useful life of an asset are capitalized.

DEPRECIATION AND AMORTIZATION. The Company depreciates buildings and 
improvements by the straight-line method over a 30-year life. Other property, 
plant, and equipment is depreciated using the straight-line method based on 
lives of 3 to 10 years. Goodwill and other intangibles are amortized using 
the straight-line method based on estimated useful lives ranging from 5 to 30 
years.

PENSION AND PROFIT SHARING PLANS. The Company has pension and profit sharing 
plans covering substantially all of its employees. Pension plan costs are 
accrued based on actuarial estimates with the pension cost funded annually.

POSTRETIREMENT BENEFITS. The company accounts for postretirement benefits 
under Statement of Financial Accounting Standards (SFAS) No. 106, EMPLOYERS' 
ACCOUNTING FOR POSTRETIREMENT BENEFITS OTHER THAN PENSIONS. SFAS No. 106 
requires an employer to recognize the cost of retiree health benefits over 
the employees' period of service.

RECLASSIFICATIONS. Certain prior years' amounts have been reclassified to 
conform with the current year presentation.

WARRANTY. The Company charges to current operations a provision, based on 
historical experience, for future warranty claims. Warranty terms on machines 
range from one to four years.

INCOME TAXES. The Company accounts for income taxes under SFAS No. 109, 
ACCOUNTING FOR INCOME TAXES. Under the asset and liability method of SFAS No. 
109, deferred tax assets and liabilities are recognized for the future tax 
consequences attributable to differences between the financial statement 
carrying amounts of existing assets and liabilities and their respective tax 
bases. Deferred tax assets and liabilities are measured using enacted tax 
rates expected to apply to taxable income in the years in which those 
temporary differences are expected to be recovered or settled. Under SFAS No. 
109, the effect on deferred tax assets and liabilities of a change in tax 
rates is recognized in income in the period that includes the enactment date.

U.S. income taxes are not provided on undistributed earnings of international 
subsidiaries which are permanently reinvested. At December 31, 1997, earnings 
permanently reinvested in international subsidiaries not subject to a U.S. 
income tax provision were $12,537,000. If ever remitted to the Company in a 
taxable distribution, U.S. income taxes would be substantially offset by 
available foreign tax credits.

EARNINGS PER SHARE. On December 31, 1997, the Company adopted SFAS No. 128, 
EARNINGS PER SHARE, which establishes new standards for calculating and 
disclosing earnings per share. All prior period earnings per share data has 
been restated to conform with the provisions of SFAS No. 128.

STOCK-BASED COMPENSATION. The Company accounts for stock-based compensation 
under Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock 
Issued to Employees. APB No. 25 requires compensation cost to be recorded on 
the date of the grant only if the current market price of the underlying 
stock exceeds the exercise price. Accordingly, no compensation cost has been 
recognized for stock option plans. The Company has adopted the 
disclosure-only provisions of SFAS No. 123, ACCOUNTING FOR STOCK-BASED 
COMPENSATION.

CASH EQUIVALENTS. The Company considers all highly liquid investments with 
maturities of three months or less, when purchased, to be cash equivalents.

REVENUE RECOGNITION. The Company recognizes revenue when title passes, which 
is usually upon shipment.

DERIVATIVE FINANCIAL INSTRUMENTS. The Company enters into forward exchange 
contracts principally to hedge the eventual dollar cash flow of foreign 
currency denominated transactions (principally British pound, Netherlands 
guilder, Australian dollar, Canadian dollar, and Japanese yen). Gains or 
losses on forward exchange contracts to hedge foreign currency denominated 
anticipated sales transactions and net exposed assets are recognized in 
income on a current basis over the term of the contracts. The Company has 
elected to treat certain forward exchange contracts as an economic hedge of 
its net investment in Tennant Holding B.V., a Netherlands-based subsidiary. 
Gains or losses on such contracts, net of related tax effect, are recognized 
on a current basis over the term of the contract and are reported as a 
separate component of shareholders' equity.


                                      23

<PAGE>

LONG-LIVED ASSETS. The Company assesses long-lived assets for impairment 
under SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND 
FOR LONG-LIVED ASSETS TO BE DISPOSED OF. SFAS No. 121 requires that 
long-lived assets be assessed for impairment loss recognition when events or 
circumstances indicate that the carrying amount of the asset may not be 
recoverable. 

NEW ACCOUNTING PRONOUNCEMENTS. In 1997, the Company adopted SFAS No. 129, 
DISCLOSURE OF INFORMATION ABOUT CAPITAL STRUCTURE, which consolidates 
existing disclosure requirements. SFAS No. 129 has no impact on the Company's 
financial statements. Also in 1997, the Financial Accounting Standards Board 
issued SFAS No. 130 and SFAS No. 131 which will be adopted by the Company in 
1998. SFAS No. 130, REPORTING COMPREHENSIVE INCOME, establishes standards for 
reporting and displaying the components of comprehensive income. The 
statement requires additional disclosures, but has no impact on consolidated 
net earnings. SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND 
RELATED INFORMATION, establishes standards for determining operating segments 
and reporting operating segment information. The Company has not yet 
evaluated the effects of this pronouncement to determine what changes, if 
any, to its current reporting format will be required.

(2)  SEGMENT REPORTING

The Company operates in one industry segment which consists of the design, 
manufacture, and sale of products and services used in the maintenance of 
nonresidential floors.

Financial data by geographic area is before interest expense and elimination 
of intercompany transactions. North America sales include sales in the United 
States, Canada and Mexico. Sales in Canada and Mexico comprise less than 10% 
of consolidated sales and are interrelated with the Company's U.S. 
operations. Product transfers from North America are generally made at prices 
that recognize return on investment objectives for both the manufacturing and 
selling units. Corporate items include general corporate expense and 
miscellaneous items such as net ESOP income and foundation contribution 
expense. Corporate assets consist primarily of Company cash and cash 
equivalents.

assets is not required since it is likely that they will be realized through 
future reversals of existing taxable temporary differences and future taxable 
income.

Income taxes paid were $14,839,000, $8,714,000, and $11,256,000, in 1997,

(9)  COMMITMENTS

The Company leases office and warehouse facilities, vehicles and office 
equipment under operating lease agreements which include both monthly and 
longer-term arrangements. Leases with initial terms of one year or more 
expire at various dates through 2006 and generally provide for extension 
options. Rentals under the leasing agreements (exclusive of real estate 
taxes, insurance, and other expenses payable under the leases) amounted to 
$3,273,000, $2,873,000, and $2,656,000, in 1997, 1996, and 1995, respectively.

The aggregate lease commitments with an initial term of one year or more at 
December 31, 1997, were $6,571,000 with minimum rentals for the periods as 
follows:

(10) SHORT-TERM BORROWINGS

Short-term bank borrowings at December 31, 1997 and 1996, were $666,000 and 
$2,530,000, respectively. In addition to the short-term bank borrowings, 
current debt includes the current portion of long-term debt and mortgages 
associated with the relocation of employees.

The weighted-average interest rates on the above short-term bank borrowings 
at December 31, 1997 and 1996, were 4.5% and 5.7%, respectively. This 
interest rate represents the weighted-average rate for the respective period 
and is calculated using the actual interest costs, exclusive of commitment 
fees, and month-end average outstanding debt.

The Company has available lines of credit with banks in the amount of 
$20,607,000 which includes a $15,000,000 line of credit requiring the Company 
to pay .2% per year commitment fee on the line of credit. This fee is 
recorded by the Company as interest expense.

In addition, the Company has outstanding letters of credit with banks in the 
amount of $2,700,000 at December 31, 1997.

(11) LONG-TERM DEBT

During 1997, 1996, and 1995, the Company paid total long-term and short-term 
interest costs of $2,019,000, $2,473,000, and $2,657,000, respectively.

(12) FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company's short-term financial instruments are valued at their carrying 
amounts in the consolidated balance sheets, which are reasonable estimates of 
their fair value due to the short maturity of the instruments. The Company's 
foreign currency forward exchange contracts are valued at fair market value, 
which is the amount the Company would receive or pay to terminate the 
contracts at the reporting date. The fair market value of the Company's 
long-term debt approximates cost, based on the borrowing rates currently 
available to the Company for bank loans with similar terms and remaining 
maturities.

(13) POSTRETIREMENT BENEFITS

The Company provides certain health care benefits for substantially all of 
its U.S. retired employees. Eligibility for those benefits is based upon a 
combination of years of service with the Company and age upon retirement from 
the Company.

The assumed annual rate of future increases in per capita cost of health care 
benefits was 8.6% for 1998, declining gradually to 5.25% in 2023 and after. 
Increasing the health care cost trend rate by 1% in each year would increase 
the accumulated benefit obligation by $276,000 as of December 31, 1997, and 
the aggregate of the service and interest costs by $29,000. The discount 
rates used in determining the accumulated benefit obligation in 1997, 1996, 
and 1995, were 6.75%, 7.0%, and 7.0%, respectively.

(14) FOREIGN CURRENCY CONTRACTS

The Company entered into several guilder forward exchange contracts for the 
purpose of hedging the net investment in Tennant Holding B.V., a 
Netherlands-based subsidiary. As of December 31, 1997, there were no 
outstanding guilder contracts. In 1997, 1996, and 1995, the Company 
recognized gains (losses), net of related tax effect, as a separate component 
of shareholders' equity of $455,000, $410,000, and $(459,000), respectively.

The Company entered into yen forward exchange contracts to hedge anticipated 
sales transactions. As of December 31, 1997, there were no outstanding yen 
contracts. In 1997, 1996, and 1995, the Company recognized gains of $0, 
$50,000, and $370,000, respectively.

The Company also entered into forward exchange contracts to hedge net exposed 
assets in Australia, Canada, and Japan. As of December 31, 1997, the Company 
had four outstanding contracts totaling $6,239,000. These contracts will 
mature in 1998 and bear rates of .6555 U.S. dollars per Australian dollar, 
1.4020 to 1.4370 Canadian dollars per U.S. dollar, and 129.55 Japanese yen 
per U.S. dollar. In 1997, 1996, and 1995, the Company recognized gains 
(losses) of $715,000, $198,000, and $(93,000), respectively.

(15) COMMON AND PREFERRED STOCK AND ADDITIONAL PAID-IN CAPITAL

The Company is authorized to issue an aggregate of 31,000,000 shares; 
30,000,000 were designated as Common Stock, having a par value of $.375 per 
share, and 1,000,000 were designated as Preferred Stock, having a par value 
of $.02 per share. The Board of Directors was authorized to establish one or 
more series of Preferred Stock, setting forth the designation of each such 
series, and fixing the relative rights and preferences of each such series.

On November 19, 1996, the Board of Directors approved a Shareholder Rights 
Plan allowing a dividend of one preferred share purchase right for each 
outstanding Common Share of the par value of $.375 per share of the Company. 
Each Right entitles the registered holder to purchase from the Company one 
one-hundredth of a Series A Junior Participating Preferred Share of the par 
value of $.02 per share of the Company at a price of $100 per one 
one-hundredth of a Preferred Share, subject to adjustment. The Rights are not 
exercisable or transferable apart from the common stock until the earlier of: 
(i) the close of business on the fifteenth day following a public 
announcement that a person or group of affiliated or associated persons has 
become an "Acquiring Person" (i.e., has become, subject to certain 
exceptions, the beneficial owner of 20% or more of the outstanding Common 
Shares), or (ii) the close of business on the fifteenth day following the 
commencement or public announcement of a tender offer or exchange offer the 
consummation of which would result in a person or group of affiliated or 
associated persons becoming, subject to certain exceptions, the beneficial 
owner of 20% or more of the outstanding Common Shares (or such later date as 
may be determined by the Board of Directors of the Company prior to a person 
or group of affiliated or associated persons becoming an Acquiring Person). 
At no time do the rights have any voting power. The rights may be redeemed by 
the Company for $.01 per right at any time prior to (and, in certain 
circumstances, within twenty days after) a person or group acquiring 20% or 
more of the common stock. The 20% thresholds do not apply to stock ownership 
by or on behalf of employee benefit plans. Under certain circumstances, the 
Board of Directors may exchange the rights for the Company's common stock or 
reduce the 20% thresholds to not less than 10%. The Rights will expire on 
December 23, 2006, unless extended or earlier redeemed or exchanged by the 
Company.

(16) STOCK PLANS, BONUSES, PENSIONS, AND PROFIT SHARING

The Company has four plans under which stock-based compensation grants are 
provided annually. The 1992 Stock Incentive Plan ("1992 Plan") and the 1995 
Stock Incentive Plan ("1995 Plan") provide for stock-based compensation 
grants to executives and key employees of the Company. The 1993 Directors 
Restricted Plan ("1993 Plan") provides for the annual retainer in the form of 
restricted shares to the non-employee Directors of the Company. The 1997 
Director's Option Plan ("1997 Plan") provides for stock option grants to 
non-employee Directors of the Company. The maximum number of shares that can 
be awarded under the respective plans is 500,000, 500,000, 50,000 and 
150,000, respectively. 

Grants under the 1992 Plan may be in the form of restricted and 
performance-related shares. Grants under the 1995 Plan may be in the form of 
restricted, performance-related and stock option shares. The grant size under 
both plans is determined by the Compensation Committee of the Board of 
Directors. 


                                      27

<PAGE>

Restricted shares are granted annually and typically have a two- or 
three-year restriction period from the effective date of the grant. During 
the restricted period, the restricted shares may not be sold or transferred, 
but the shares entitle the participants to dividend and voting rights. In 
1997, 1996, and 1995, respectively, 28,000, 26,000, and 18,000 restricted 
shares were granted. The weighted-average fair value of stock on the grant 
date was $31.35, $24.57, and $23.55 per share in 1997, 1996, and 1995, 
respectively.

Performance-related shares are granted annually and are payable if the 
Company achieves certain financial performance goals over each four-year 
period following the grant. In 1997, 1996, and 1995, respectively, 34,000, 
46,000, and 35,000 performance shares were granted. The weighted-average fair 
value of stock on the grant date was $26.75, $23.25, and $23.56 per share in 
1997, 1996, and 1995, respectively.

Under the 1995 Plan and the 1997 Plan, 10-year fixed stock options are 
granted annually at a price equal to the stock's fair market value on the 
date of the grant. Options are exercisable on a cumulative basis at a rate of 
25% per year. The fair value of options at the date of grant is estimated 
using the Black-Scholes option pricing model with the following 
weighted-average assumptions used for the 1997, 1996 and 1995 grants, 
respectively: dividend yield of 2.6%, 2.6% and 2.6%; expected volatility of 
19%,18% and 22%; risk-free interest rates of 6.2%, 5.5% and 7.4%; and 
expected life of option of five years. A summary of the status of the 
Company's stock option transactions during 1997, 1996 and 1995 is shown below:

The weighted-average fair value of each option granted was $6.11, $4.53 and 
$6.22 in 1997, 1996 and 1995, respectively. At December 31, 1997, outstanding 
options had exercise prices between $22.00 and $37.50 per share and a 
weighted-average contractual life of eight years.

In 1997, 1996, and 1995, respectively, expenses of $6,192,000, $2,731,000, 
and $2,310,000, were charged to operations for restricted and 
performance-related awards. The Company has adopted the disclosure-only 
provision of SFAS No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION. Had 
stock-based compensation cost, determined consistent with the provisions of 
SFAS No. 123, been charged to the Company's net earnings, net earnings per 
share would have been reduced to the pro forma amounts indicated below 
(dollars in Thousands, except per share amounts):

The effects of applying SFAS No. 123 in this pro forma disclosure are not 
indicative of future amounts, because additional awards in future years are 
anticipated.

The Company also has a matching contribution program available to all 
employees who make 401(k) contributions. Under this program, the Company 
makes matching contributions up to a maximum of 4% of an employee's earnings. 
Employee contributions invested in Company common stock are matched at the 
rate of 35%, and contributions not invested in Company common stock are 
matched at the rate of 15%. Expenses related to matching contributions were 
$689,000, $695,000, and $635,000 in 1997, 1996, and 1995, respectively.

The Company has a Defined Benefit Pension Plan (available to most U.S. 
employees). Plan benefits are based on the employee's years of service and 
compensation during the highest five consecutive years of service of the 
final ten years of employment. The Company's policy has been to fund this 
plan to the maximum allowed by ERISA rules. Contributions are intended to 
provide benefits attributed to service to date, and for service-related 
benefits expected to be earned in the future.

Net pension expense for the three years ended December 31, 1997, is as 
follows:

Retirement benefits for eligible employees in foreign locations are funded 
principally through either annuity or government programs.

During 1990, the Company established a leveraged Employee Stock Ownership 
Plan (ESOP) by amending its Profit Sharing Plan to add ESOP features. The 
ESOP covers substantially all domestic employees following completion of one 
year of service. The shares required for the Company's matching contribution 
program, as well as the Company's Profit Sharing Plan, are provided 
principally by the Company's ESOP, supplemented as needed by newly issued 
shares. The Company makes annual contributions to the ESOP equal to the 
ESOP's debt service less dividends received by the ESOP. All dividends 
received by the ESOP are used to pay debt service. The ESOP shares initially 
were pledged as collateral for its debt. As the debt is repaid, shares are 
released from collateral and allocated to employees who made 401(k) 
contributions that year, as well as to profit sharing participants, based on 
the proportion of debt service paid in the year. The Company accounts for the 
ESOP in accordance with EITF Issue 89-8, Expense Recognition for Employee 
Stock Ownership Plans. Accordingly, the shares pledged as collateral are 
reported as unearned ESOP shares in the consolidated balance sheets. As 
shares are released from collateral, the Company reports compensation expense 
equal to the cost of the shares to ESOP. ESOP shares are considered 
outstanding in EPS computations, and dividends on allocated and unallocated 
shares are recorded as a reduction of retained earnings.

The Company's cash contribution to the ESOP during 1997, 1996, and 1995 was 
$1,263,000, $1,303,000, and $1,307,000, respectively. Accrued expenses in 
excess of benefits provided to employees through the ESOP, which were charged 
to miscellaneous expense, were $138,000, $542,000, and $778,000, in 1997, 
1996, and 1995, respectively. Interest earned and received on the Company 
loan to the ESOP was $1,496,000, $1,550,000, and $1,598,000, in 1997, 1996, 
and 1995, respectively. Dividends on the Company shares held by the ESOP used 
for debt service were $787,000, $755,000, and $738,000 in 1997, 1996, and 
1995, respectively. At December 31, 1997, the ESOP indebtedness to the 
Company, which bears an interest rate of 10.05% and is due December 31, 2009, 
was $14,751,000.

The ESOP shares as of December 31 were as follows:
