Proposal 3 Grant of Restricted Common Shares as Share-Based Compensation for Directors

We would like to adapt a program (the “Program”) to grant restricted common shares to the Directors who are Audit and Supervisory Board members of the Company. The Company requests approval for the determination of the limit on the amount of monetary compensation claims provided for the purpose of granting eligible Directors restricted common shares separately from the basic remuneration of Directors who are Audit and Supervisory Board members, and for the determination of the limit on the total number of restricted shares to be delivered as follows:

The Program term is for 30 years, from March 1, 2026 to February 29, 2056. Upon the introduction of this Program, the limit on the cumulative aggregate amount of the share-based compensation provided through the grant of restricted common shares shall be ¥4.4 billion, and the limit on the total number of shares to be granted shall be 11,132,197 shares. The amount of share-based compensation based on the Company’s common shares granted through the issuance of new shares or the disposition of treasury shares under this Program is calculated by multiplying net assets per share by the number of shares granted through the issuance of new shares or the disposition of treasury shares.

We have determined that this proposal is appropriate as a program to provide recipients with incentives to contribute to the long-term and stable enhancement of the Company’s corporate value. We have also determined that this is a sound management measure because, unlike the provision of cash, share-based compensation will not use any cash resources of the Company. Details of the restricted common shares and the conditions for granting are as follows:

	i)	Eligible recipients:
		The Company’s Directors who are Audit and Supervisory Board members.

	ii)	Transfer and resale restriction period:
		Transfer or resale is prohibited for 20 years from the date of the grant.

	iii)	Grant method:
		By entering an agreement on the allocation of restricted common shares, the Company issues or disposes of the Company’s common shares.

	iv)	Other:
		Detailed conditions regarding restricted shares shall be determined by the resolution of the Board of Directors.
