Stock Ownership Guidelines

DISCO believes that it is important for executive officers (including those who concurrently hold a director position) to share value with shareholders and work toward improving corporate value consistently over the long term. Therefore, the following stockholding guidelines have been established.

Stock Ownership Guidelines:
The target amount is to be reached within either 5 years of the effective date of these guidelines or of appointment of the individual to a designated executive position.

Title	Target holdings amount※
CEO	5x	Annual base salary
Executive officers with title	2x
Other executive officers	1.5x

^※The target holdings amount is to be calculated based on the average closing price of the stock at the end of each month over the 5 most recent corporate fiscal years.
