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

COOPER INDUSTRIES

Sales for the three months ended July 31, 2001, declined 5% to 10%, compared
with last year.

     o    Currency translation continues to have a modest negative impact.

ELECTRICAL PRODUCTS

Sales for the three months ended July 31, 2001, declined 5% to 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 retail and industrial markets and
          slowing commercial and residential construction led to declining
          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 distributors' efforts to rationalize inventory levels.

     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    European-based business demand has weakened slightly.

     o    Competitive pressures continue to impact pricing in many markets.

     o    Currency translation effects remain modestly negative.

TOOLS AND HARDWARE

Sales for the three months ended July 31, 2001, declined 5% to 10%, compared
with last year.

     o    Assembly equipment shipments, particularly from our European
          operations, continue at levels higher than last year.

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

     o    Currency translation effects remain modestly negative.
