                  CLARCOR TO ACQUIRE THREE FILTRATION COMPANIES
                   ACQUISITIONS WILL INCREASE REVENUES BY 35%


ROCKFORD, IL, SEPTEMBER 13, 1999 - CLARCOR INC. (NYSE: CLC) today announced that
it has signed a definitive agreement to acquire, effective September 1, 1999,
three filtration businesses from Mark IV Industries. The companies are:
PUROLATOR PRODUCTS AIR FILTRATION COMPANY, FACET INTERNATIONAL and
PUROLATOR-FACET FILTER PRODUCTS.

The purchase price for the three companies is approximately $136 million. No
debt was assumed. The transaction is structured primarily as an acquisition of
assets and will provide CLARCOR with deductible goodwill having a net present
value tax benefit to CLARCOR of more than $11 million. In the most recently
completed fiscal year for the three companies, sales totaled $150 million and
will increase CLARCOR's sales by approximately 35%. For the year ended November
30, 1998, CLARCOR had net sales of $427 million.

"This is a significant opportunity for CLARCOR. By acquiring three quality
businesses, it will increase our total sales by approximately 35% in the first
year," said Larry Gloyd, CLARCOR's Chairman and CEO. "These are good businesses
with solid margins, and although we expect the acquisitions to be $0.01-$0.02
dilutive to diluted earnings per share in fiscal 2000, they should be accretive
thereafter. Looking ahead, we see the potential for further improvement in sales
and margins, plus attractive returns on invested capital."

Gloyd emphasized, "These acquisitions fit well with our strategy to provide our
customers with their complete filter requirements, including supply,
installation and service, for all types of manufacturing plants, distribution
centers, retail stores, office facilities and engine applications. These
companies will add new types of filtration products and systems to our product
lines with recognized brand names and give us access to new markets and
customers, particularly in the aviation and fluid processing industries. They
will also increase our manufacturing leverage, which will enable us to reduce
costs and improve margins. In conclusion, this acquisition will significantly
strengthen CLARCOR and our presence in the filtration marketplace."

Purolator Products Air Filtration Company (PPAFC) is a manufacturer of a wide
range of air filters used in heating, ventilation and air conditioning systems.
PPAFC is based in Henderson, North Carolina, with two manufacturing sites in

opportunities for improved operating efficiencies.
