OBSERVATIONS ON RECENT SALES TRENDS, FOR THE THREE MONTHS ENDED NOVEMBER 30,
2001.

COOPER INDUSTRIES

Sales for the three months ended November 30, 2001, declined 8%-10%, compared
with last year.

   o  Currency translation continues to have a modest negative impact.

ELECTRICAL PRODUCTS

Sales for the three months ended November 30, 2001, declined 8%-10%, compared
with last year.

   o  Demand for hazardous duty electrical construction materials showed
      continued improvement as increased capital spending in the energy and
      petrochemical sectors spurred project activity.

   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 effects, though negative, have moderated.

TOOLS AND HARDWARE

Sales for the three months ended November 30, 2001, declined 11%-13%, compared
with last year.

   o  Assembly equipment shipments, particularly from European operations,
      continue at good levels.

   o  Slowing industrial and electronic assembly activity in North America has
      led to reduced demand for hand and power tools.

   o  Currency translation effects have been modestly negative.

Note: Includes impacts of acquisitions and divestitures.
