FIRST QUARTER 2003 OPERATING REVIEW
     ROCKFORD, IL, MONDAY, MARCH 24, 2003-- CLARCOR INC. (NYSE: CLC) today
reported results for the first quarter ended March 1, 2003. Sales in the first
quarter of 2003 increased by $13 million, an 8% increase compared to 2002.
Operating profit in 2003 increased by 8% and net earnings by 20% compared to the
same quarter in 2002. Diluted earnings per share increased by 19%. A weaker U.S.
dollar improved sales by approximately $1.5 million. Overall, excluding the
impact of the favorable currency translation and an acquisition made in June
2002, sales grew by 5% from last year's first quarter. Cash flow from operations
was $13.2 million in the first quarter compared to $12.0 million in the same
quarter in 2002.

Norm Johnson, CLARCOR's Chairman and Chief Executive Officer, said, "We had a
very good first quarter. Sales, net earnings and cash flow from operations were
at the high end of the range we expected when the quarter began. We were able to
absorb significantly higher pension, health care and insurance costs and still
increase operating profit this quarter by 8%. Increased cash flow also enabled
us to continue to reduce our debt by over $12 million, further strengthening an
already strong balance sheet. Higher operating profit, significantly reduced
debt and lower interest rates resulted in a 20% increase in net earnings over
last year.





"Our Engine/Mobile segment had a strong first quarter with sales increasing by
over 15%, including the impact from the acquisition of Locker Filtration in June
2002. Excluding that acquisition, sales still grew by over 8%, primarily from
growth in the heavy-duty aftermarket. We also saw increased filter sales to
original equipment manufacturers. Segment operating profit grew by 13% driven by
cost controls and a favorable sales mix.

"Sales at our Industrial/Environmental segment rose by over 5%. On a product
basis, we saw increased sales of HVAC air filters, filters used in oil drilling
and liquid process filters sold to the beverage industry. The continued slow
pace of domestic and international capital spending reduced sales of air quality
systems and sales of filters used in the aerospace industry below our original
expectations. Domestic manufacturing activity generally affects sales in this
segment more than it does sales in our Engine/Mobile Filtration segment.
However, we expect recent product introductions, such as a new line of dust
collectors and additional filter products for the oil drilling industry, to
favorably impact sales later this year.

"The focus in our Industrial/Environmental segment in 2003 continues to be to
improve operating margins towards our goal of 10% on an annual basis within
three years. Although margins in the first quarter were not as strong as we
expected, we believe that margins will improve significantly as the year
progresses. As sales increase in future quarters, we will be able to leverage
our fixed manufacturing and administrative costs. In addition, we are
rationalizing product lines at several manufacturing plants and reorganizing
other facilities to improve productivity. Though we are absorbing costs from
these initiatives currently, we expect a positive impact on margins in the
future.

"Our Packaging segment had a slow first quarter with a small decline in sales
and operating profit from last year. Although metal product sales were good,
plastic product sales were below last year's levels. The first quarter is
normally the weakest for our Packaging segment and is not usually a good
indication of activity for the rest of the year. We remain confident that both
Packaging sales and profits will improve as the year progresses and will exceed
last year's levels.

 "We continue to expect that diluted earnings per share for 2003 will be in the
$1.92 to $2.02 range. Most of our sales are in the filtration aftermarket, and
therefore our revenues tend to be more stable in difficult economic times than
are sales of companies that sell primarily into the OEM markets. Nevertheless,
we are not immune to the economy, and another recession so soon after the last
one would certainly affect us. Likewise, the war in the Middle East certainly
adds an uncertainty that makes the future less clear. Still, we see no reason to
change our earnings expectations at this time, particularly after a good first
quarter.



                                       2




"We remain very optimistic regarding CLARCOR's future. The positive impact of
our Total Filtration Program is becoming more and more evident. It has enabled
us to offer more products to our current customers and to build new
relationships with companies we had never sold to previously. Our Total
Filtration Program combined with the efforts of all our operating companies to
build their individual sales through new products and new customer relationships
will clearly drive our growth this year. Even in a difficult economic
environment and with a war of uncertain duration, we remain committed to our
goal of improved sales and earnings in 2003."

at 10:00 am CST on March 24, 2003. Interested parties can listen to the
