2. Reasons for the Revision
   

   Ongoing profitability improvement measures centering on the reduction of fixed costs, implemented across the OMRON Group, have produced positive effects. In addition, recovery of production mainly in Japan and China has driven up demand for control components and systems, OMRON's mainstay business. Robust performance in the healthcare and medical devices business has also led to an improved outlook for consolidated performance in fiscal 2009.

   The OMRON Group is determined to thoroughly promote profitability measures, and continue to exert a concerted effort to implement business structure reform, in order to achieve steady restoration of performance.

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.
