3. Reasons for the Revision
   

   The Cumulative Consolidated Forecast for the First Two Quarters
   As with the 1st quarter of fiscal 2010, the 2nd quarter has been seeing a mild economic recovery in Japan and internationally, and a resultant rebound in capital investment by the manufacturing industry and other industries is expected to become an important driving force behind OMRON's business performance.

   The Consolidated Forecast for Fiscal 2010
   Although current economic uncertainty and the effects of the high value of the yen will presumably have an adverse effect on OMRON's business performance over the course of the current fiscal year, the conditions seen so far in the first and second quarters are expected to continue, and the previous consolidated performance forecast for the 2010 fiscal year has therefore been revised upwards.

Note: The above forecast is based on information available to the Company at the time of this announcement. Actual results may differ materially from the forecast due to various factors.
