OBSERVATIONS ON RECENT SALES TRENDS, FOR THE THREE MONTHS ENDED DECEMBER 31,
2001.

COOPER INDUSTRIES
Sales for the three months ended December 31, 2001, declined 11%, compared with
last year.

     o    Overall, business showed signs of weakness toward the end of the three
          month period.

     o    Currency translation had a negligible impact.

ELECTRICAL PRODUCTS

Sales for the three months ended December 31, 2001, declined 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
          showed continued improvement.

     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 December 31, 2001, declined 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.
