OBSERVATIONS ON RECENT SALES TRENDS, FOR THE THREE MONTHS ENDED FEBRUARY 28,
2002.

COOPER INDUSTRIES
Sales for the three months ended February 28, 2002, declined 8-10%, compared
with last year.
    o  Currency translation had a negligible impact.
ELECTRICAL PRODUCTS
Sales for the three months ended February 28, 2002, declined 7-9%, compared with
last year.
    o  Demand for hazardous duty electrical construction materials decreased in
       the domestic market while remaining strong in Europe.
    o  Continued softness in domestic industrial and commercial markets led to
       lower demand for lighting fixtures and wiring devices.
    o  Sales of electrical and electronic fuses, other circuit protection
       products and enclosures were considerably weakened by lower end-user
       demand and distributor inventory reductions.
    o  Continued uncertainty in the power delivery marketplace has hampered
       utilities' investments in distribution system products. Demand for
       distribution transformers and power management products remains weak.
    o  UK and European demand for lighting fixtures and security products has
       slowed.
    o  Competitive pressures continue to impact pricing in many markets.
    o  Currency translation had a negligible impact.
TOOLS AND HARDWARE
Sales for the three months ended February 28, 2002, declined 16-18%, compared
with last year.
    o  Assembly equipment shipments to the auto industry are down from last
       year's levels.
    o  Slowing industrial and electronic assembly activity in North America has
       led to reduced demand for hand and power tools. European markets for hand
       tools have weakened.
    o  Currency translation effects have been modestly negative.

Note: Includes impacts of acquisitions and divestitures.
