Notification of Company Name Change

1 juillet 2004

I am delighted to announce that COS changed its name from COS Co., Ltd. to HORIBA Advanced Techno, Co.,Ltd. as of July 1, 2004.

We believe that this will further enhance the company's consciousness and responsibility as a member of the Horiba Group, an integrated manufacturer of measuring and analytical devices, and that it will serve to deepen collaboration with other Group companies and enable us to provide total solutions that give complete customer satisfaction in line with our motto that the "Horiba Group Is One Company."

All employees will dedicate themselves afresh to the creation of a company that achieves progress constantly, making every effort to meet the expectations of all customers and stakeholders. We hope to continue receiving your guidance and goodwill.
