Proposal 2

Proposal 3(Note) The requirements for approval of the proposals resolved are as follows:● Proposal 1 requires approval by a majority of the voting rights of shareholders in attendance at the General Meeting ofShareholders.
● Proposal 2 and Proposal 3 require approval by a majority of the voting rights of shareholders in attendance at theGeneral Meeting of Shareholders, which is attended by shareholders holding, in the aggregate, no less than one-thirdof all voting rights held by shareholders eligible to exercise voting rights.
(4) Reason why some of the voting rights of shareholders who attended the General Meeting of Shareholders were not included in thetotal number of votes
It could not be confirmed whether the votes cast by some shareholders who attended on the day of the General Meeting ofShareholders were votes in favor, against, or abstaining. These were not included in the total number of votes as the total numberof votes cast in advance up to the day before the General Meeting of Shareholders and those cast by other shareholders inattendance on the day that could be confirmed was already sufficient to meet the requirements for approval of the proposals andthe resolutions were thereby enacted lawfully under the Companies Act.
