as follows.

     Komatsu's consolidated financial statements conform with accounting

       *This growth rate is indicated for foreign companies only. Statistical
        data for Chinese-made equipment are not available.

       **Other regions consist of the Middle East, Africa and CIS, Asia
         Pacific, and Central and South Americas.

.. In Japan, Komatsu faced a drastic drop of 30% in demand for the first quarter
when compared to annual demand (- 15%) projected at the beginning of the current
fiscal year.

                                       1



.. In North America, the Company met a decline in demand for mining equipment,
which upturned last year. As to general construction equipment, while signs for
recovery in demand emerged at the start of 2002, the degree of decline is
growing, somewhat overshadowing the possibility of demand recovery today.

.. In Europe, while recovery of demand emerged in the United Kingdom, Italy and
some other countries, demand continued to fall in Germany, the largest market of
Europe, resulting in negative growth in Europe as a whole.

.. In Southeast Asia, overall demand kept an upward outlook. Nevertheless, there
were some industrial sectors, such as forestry, which lagged behind in demand
recovery.

.. In China, demand for medium-sized hydraulic excavators continued to expand
substantially during the first quarter of the current fiscal year. It is
important to realize, however, that this period is known to accommodate the
largest demand of the year.

.. In other regions, overall demand increased. Demand was particularly strong in
Saudi Arabia, UAE, Iran and other Middle East countries.

[Electronics Business]
.. Demand for silicon wafers has recovered dynamically since the beginning of
this year after bottoming out in the summer of 2001. This market recovery was
driven by supplementary demand for semiconductor inventories resulting from
worldwide progress in inventory adjustment of IT-related equipment. Worldwide
demand for silicon wafers in the first quarter of the current fiscal year
expanded about 29% (on an area basis) from the corresponding period last year.

.. Demand for polycrystalline silicon for use in silicon wafers improved slowly
after bottoming out in 2001, supported by business recovery of the major client
industry of silicon wafers. The Company projects that demand in the first
quarter of the current fiscal year should record double-digit growth over the
preceding quarter.

.. Demand for thermoelectric modules for use in fiber optic communication
networks remained sluggish for the first quarter of the current fiscal year,
reflecting the lack of growth in facilities investment of telecommunications in
North America.

[Others]
.. Concerning industrial vehicles (forklift trucks), demand continued to advance
in the United States, the world's largest market. Meanwhile, Japanese demand
declined 10% from the corresponding period last year.

.. With respect to industrial machinery such as sheet metal machinery and
presses, overseas demand increased 12% on a basis of orders received over the
corresponding period last year, against the backdrop of production transfers to
overseas by manufacturers of automotive sheet metal parts. Contrarily, Japanese
demand dropped 25% as affected by the sluggish economy.
