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

COOPER INDUSTRIES
Sales for the three months ended March 31, 2001, grew 5%, compared with last
year.

    o Revenues increased as a result of recent acquisitions.
    o Currency translation continues to have a modest negative impact.

ELECTRICAL PRODUCTS
Sales for the three months ended March 31, 2001, grew 8%, compared with last
year.

    o Telecommunications and electronics product sales were considerably
      weakened by lower demand from key customers, affecting sales of fuses,
      other circuit protection products and enclosures.
    o Construction-related markets continued to soften, impacting sales of many
      products, including utility products, lighting fixtures and wiring
      devices.
    o Utility spending on distribution system products - distribution
      transformers and power management products - remains weak.
    o Declining demand for electrical construction materials continued in North
      America, though somewhat offset by recent improvements from international
      markets.
    o European-based business demand remained firm.
    o Competitive pressures impacted pricing in many markets.
    o Recent acquisitions, B-Line and Eagle Electric being the two most
      significant of these, continue to provide an increase to sales.
    o Currency translation effects remain modestly negative.

TOOLS AND HARDWARE
Sales for the three months ended March 31, 2001, declined 7%, compared with last
year.

    o Slowing industrial activity in North America has led to reduced demand for
      power and hand tools.
    o Assembly equipment shipments, particularly from our European operations,
      continue at levels higher than last year.
    o Currency translation effects remain modestly negative.

Note: Includes impacts of acquisitions and divestitures.
