Based on the "Action Program to Promote Reductions in Stock Investment Units" announced by the Tokyo Stock Exchange, we have been deliberating on the reduction of investment units. Since the second half of 2005, ADEKA's stock price was on a rising trend, currently hovering just above 2,000 yen. Since this greatly exceeds the goal of "under 500,000 yen" set by the Tokyo Stock Exchange, we have decided to reduce the number of shares per unit in order to improve the market liquidity of our stock and seek increased participation from private investors.
1. Contents of change: The number of shares per unit will be changed from 1,000 shares to 100 shares.
2. Planned date of change: May 1, 2006
