3. Partial Change of Articles of Incorporation(1) Purpose of partial change of Articles of Incorporation
To facilitate the smooth execution of administrative procedures related to the convocation of Ordinary
General Meetings of Shareholders and other matters, Article 13 of the current Articles of Incorporation(Record Dates of Ordinary General Meetings of Shareholders) specifies the record dates of Ordinary
General Meetings of Shareholders, in accordance with the provisions of Article 124, Paragraph 3 of theCompanies Act. If agenda item No. 1 above, which regards approval of the plan for the Share Transfer,
is approved at the Extraordinary Meeting, such that the Share Transfer becomes effective as of Monday,April 1, 2024, the Company will have only one shareholder, namely the joint holding company. As such,the stipulation of record dates for Ordinary General Meetings of Shareholders will become unnecessary.
For this reason, it is proposed that Article 13 of the current Articles of Incorporation (Record Dates ofOrdinary General Meetings of Shareholders), which specifies the record dates of Ordinary General
Meetings of Shareholders, be abolished, such that the current Article 14 in the Articles of Incorporation
becomes Article 13 and so on. (This partial change in the Articles of Incorporation is hereinafter referred
to as “the Partial Change of the Articles of Incorporation.”)If agenda item No. 1 above, “Approval of plan for the Share Transfer,” is approved as drafted at
the Extraordinary Meeting; the Share Transfer plan as approved in agenda item No. 1 by the day before
Sunday, October 31, 2024 remains in effect; and the Share Transfer is not suspended, the Partial Changeof the Articles of Incorporation will come into effect on Sunday, October 31, 2024.
