Proposal 2(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 theGeneral Meeting of Shareholders.

Reason why some of the voting rights of shareholders who attended the General Meeting of Shareholders were
not included in the total number of votes
It could not be confirmed whether the votes cast by some shareholders who attended on the day of the General
Meeting of Shareholders were votes in favor, against, or abstaining. These were not included in the total
number of votes as the total number of votes cast in advance up to the day before the General Meeting ofShareholders and those cast by other shareholders in attendance on the day that could be confirmed was alreadysufficient to meet the requirements for approval of the proposals and the resolutions were thereby enacted
lawfully under the Companies Act.
