      (Note) 1 The requirement for the approval of each Proposal is as follows.

      The requirement of the approval of Proposal No.1 is the attendance of shareholders who have one-third or more of the voting rights of shareholders who are eligible to exercise voting rights, and two-thirds or

      more of the vote in favor cast by the said attending shareholders who are eligible to exercise voting rights.

      The requirement for the approval of Proposal No.2 is the attendance of shareholders who have one-third or more of the voting rights of shareholders who are eligible to exercise voting rights, and a majority vote in favor cast by the said attending shareholders who are eligible to exercise voting rights.

      (Note) 2 Rate of approval is the proportion of the number of confirmed approving votes for the Proposal exercised by shareholders who voted before or on the day of the General Meeting of Shareholders to the number of voting rights exercised by attending shareholders who are eligible to exercise voting rights (before or on the day of the General Meeting of Shareholders (including the number of voting rights held by shareholders who left early)).

    4. Reason for not including a certain number of the voting rights of attending shareholders in the number of voting rights

The Proposals were resolved pursuant to the Companies Act because the requirements necessary for the approval of each of the Proposals were satisfied when a certain number of votes of attending shareholders were confirmed as approving or disapproving each of the Proposals, in addition to the voting rights exercised by the day prior to the General Meeting of Shareholders. Therefore, the Company has not counted the number of voting rights of certain shareholders present at the General Meeting of Shareholders, as to which the Company was unable to confirm approval, disapproval or abstention.
