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

COOPER INDUSTRIES
Sales for the three months ended August 31, 2001, declined 10% to 12%, compared
with last year.
o Currency translation continues to have a modest negative impact.

ELECTRICAL PRODUCTS
Sales for the three months ended August 31, 2001, declined 10% to 12%, 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 continued to weaken.
     o Competitive pressures continue to impact pricing in many markets.
     o Currency translation effects have moderated.

TOOLS AND HARDWARE
Sales for the three months ended
August 31, 2001, declined 6% to 8%, 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 have moderated.

Note: Includes impacts of acquisitions and divestitures.
