[Description]

1. Reasons for Necessity of Issuing the Stock Acquisition Rights on Preferential Terms and Conditions

The Company would like to grant Stock Acquisition Rights to employees of the Company and to the directors of major subsidiaries of the Company, for the purpose of raising their morale and their motivation to contribute to the improvement of the consolidated performance of the Company.

2. Details of the Stock Acquisition Rights and the Maximum Number of Such Rights That the Board of Directors Can Decide to Issue Within the Scope of Authority Granted by a Resolution at this General Meeting of Shareholders

(1) The maximum number of the Stock Acquisition Rights for which the terms and conditions of the issue can be determined based on the authority granted by this General Meeting of Shareholders
The maximum number of Stock Acquisition Rights to be issued under the conditions described in 2. (3) below shall be 323.
The maximum number of ordinary shares to be issued upon the exercise of the Stock Acquisition Rights shall be 323,000 shares, and if the Number of Shares Granted (defined below) subject to Stock Acquisition Rights has been adjusted as provided for in 2. (3) below, the maximum number of ordinary shares to be issued shall be the number arrived at by multiplying the above mentioned maximum number of the Stock Acquisition Rights by the adjusted number of shares in connection with the Stock Acquisition Rights.

(2) The Company may issue Stock Acquisition Rights in question without consideration.

(3) Details of the Stock Acquisition Rights to be issued on the basis of the authority granted by this General Meeting of Shareholders

1) Type and number of shares to be issued upon the exercise of Stock Acquisition Rights
The shares to be issued for the Stock Acquisition Rights shall be ordinary shares, and the number of shares subject to one Stock Acquisition Right (hereinafter "Number of Shares Granted") shall be 1,000 shares. However, after the resolution date of this agendum (hereinafter "Resolution Date"), if the Company effects a stock split of its ordinary shares (including allotment of ordinary shares to shareholders without consideration; the same applies hereinafter) or effects a stock consolidation, the Number of Shares subject to one Stock Acquisition Right shall be adjusted proportionately, in accordance with the ratio of the stock split or the stock consolidation in question. Also, if it is necessary to adjust the Number of Shares Granted after the Resolution Date for other than the aforementioned reasons, the Company shall adjust the Number of Shares Granted in connection with the aforementioned Stock Acquisition Rights to the extent reasonable.
Fractions of less than one (1) share resulting from the foregoing adjustment shall be rounded down.

2) Amount of assets paid upon exercise of the Stock Acquisition Rights
The amount of assets paid upon exercise of the Stock Acquisition Rights shall be the amount calculated by multiplying the paid-in amount per share to be transferred upon exercise of the Stock Acquisition Rights (hereinafter "Exercise Price") by the Number of Shares subject to one Stock Acquisition Right.
The Exercise Price shall be the amount calculated by multiplying 1.05 by the average of the closing price of the Company's ordinary shares of each day in regular trading during the month (excluding days when there was no transaction of the Company's ordinary shares) (hereinafter "Closing Price") at the Tokyo Stock Exchange, immediately preceding the month in which the date of allotment of the Stock Acquisition Rights falls (hereinafter "Allotment Date"), with fractions of less than one (1) yen rounded up to a whole yen. However, if the Rights Exercise Price is lower than the Closing Price on the Allotment Date (if there is no Closing Price on that date, the Closing Price on the immediately preceding transaction date shall be applied), the Closing Price on the Allotment Date shall be applied.

In addition, the Exercise Price shall be adjusted as follows.

i. If the Company effects a stock split or stock consolidation after the Allotment Date of the Stock Acquisition Rights, the Exercise Price shall be adjusted in accordance with the following formula, with fractions of less than one (1) yen resulting from the adjustment being rounded up to a whole yen.

ii. After the Allotment Date of the Stock Acquisition Rights, if the Company issues new ordinary shares or disposes of the Company's shares in treasury at a price below the market price, the Exercise Price shall be adjusted in accordance with the following formula, with fractions of less than one (1) yen being rounded up to a whole yen. However, this shall not apply to the cases where issue or disposition of ordinary shares is made upon exchange of securities exchangeable for Company's ordinary shares, or upon exercise of Stock Acquisition Rights (including corporate bonds with Stock Acquisition Rights).

In addition, the "Number of currently issued shares" in the formula above shall exclude the number of the Company's shares in treasury, and when disposing of the Company's shares in treasury, the term "Number of newly issued shares" shall be read as "Number of the Company's shares in treasury for disposal."

iii. After the Allotment Date of the Stock Acquisition Rights, if the Company allots shares of the Company of a class other than the ordinary shares without consideration to the holders of the ordinary shares of the Company, or pays dividends in the form of shares of another company to the holders of the ordinary shares, and if, in consideration of all factors in the situation, there is a need to adjust the Exercise Price, the Company shall adjust the Exercise Price to the extent reasonable.
