Eisai resolved "the Policy for Protection of the Company's Corporate Value and Common Interests of Shareholders" at the Board of Directors on February 28, 2006. The Policy is a prior notice type plan. It sets forth an orderly procedure to be followed when an acquisition of large block of our shares is planned to allow sufficient time and information for shareholders to make appropriate judgments. It also enables the Company to issue new stock options to all shareholders and the acquirer is not entitled to exercise and dilute its voting rights of the acquirer if appropriate procedures are not followed by the acquirer or if the acquisition is inappropriate and would undermine the corporate value and common interests of the shareholders. By these, this Policy is designed to deter inappropriate acquisitions. With this shelf registration, it will be possible to promptly issue stock options in accordance with rights offering to shareholders.
