III. Reasons for the Revision

     In the construction and mining equipment business, domestic demand for
     construction equipment is anticipated to significantly decrease from that
     previously forecast due to the adverse effect of curtailed construction
     investment led by sluggish public outlays. Overseas, although sales in
     China made gains and the mining equipment market experienced a rebound, in
     the key North America market, demand continued to decline, and in Southeast
     Asia, market recovery was delayed. All in all, these developments led to
     lower than expected earnings being forecast.

       In the electronics business, a steep recession in the global
     semiconductor industry impacted the silicon wafer industry, causing the
     market to remain very soft. As a result, the performance of Komatsu
     Electronic Metals Co., Ltd. is expected to deteriorate more than previously
     forecast. Even demand for thermoelectric modules for optical
     communications, which grew significantly in the pervious term, declined
     sharply, and the situation is expected to continue. Thus, earnings are seen
     falling from those initially forecast.

       In future, Komatsu will strive to secure earnings through full-scale
     marketing of its GALEO series of construction equipment in Japan and make
     company-wide efforts to further reduce fixed costs. However, given the
     outlook for a continued difficult management environment, the consolidated
     and non-consolidated forecasts for the interim- and full-year terms have
     also been revised downward as stated earlier.
