Tennant Company to Acquire Brazilian Market Leader Sociedade Alfa Ltda.

MINNEAPOLIS, Minn., Feb. 22, 2008—

Tennant Company (NYSE: TNC), a world leader in designing, manufacturing and marketing solutions that help create a cleaner, safer world, today announced that it has entered into a purchase agreement with Sociedade Alfa Ltda., maker of the Alfa brand commercial cleaning machines. The deal is expected to close within 30 to 60 days. Completion of the transaction is subject to certain government and other third-party consents, and other customary closing conditions. Terms of the agreement have not been disclosed.

Sociedade Alfa Ltda., based in Sao Paulo, Brazil, with a branch office in Curitiba and a plant in Limeira, is recognized as the Brazilian market leader in the cleaning industry, reporting just over $9 million in sales revenue for 2007.

“Tennant Company is interested in opportunities that expand our sales and service networks and enhance our suite of product offerings. We’re very excited to see all three of these coming together with Alfa,” said Chris Killingstad, President and CEO of Tennant Company. “Alfa’s strong name recognition in the commercial equipment market, combined with Tennant’s industrial equipment products and specialty floor coatings, creates a tremendous foothold and foundation for growth,” Killingstad said.

Salvator Haim, main shareholder of Sociedade Alfa comments: “This merger ratifies our opinion after 30 years in the business that the best way to benefit in the Brazilian and South American cleaning equipment market is to combine local products and service with international ‘know how’. It is particularly motivating to join with Tennant Company to produce and deliver our customers the very best of global technology."

In addition to sales of its well-known Alfa brand of equipment, the company has been a distributor of other branded cleaning equipment. Going forward, the newly combined company will sell only Tennant and Alfa brand equipment.

This is the second acquisition announced by Tennant Company in 2008. The company recently announced it has signed a purchase agreement with Applied Sweepers, maker of Green Machines® brand outdoor cleaning equipment, based in Falkirk, Scotland.

Killingstad noted that these transactions are consistent with the company's strategy of pursuing add-on acquisitions to gain access to interesting products or to expand its global sales and service coverage.
