Details 1. Purpose of the issuance of subscription rights to new shares as stock options

The Company reviewed its remuneration system for the executives in 2013, aiming to strengthen its features to reward the executives for the Company's achievement of the medium-and-long-term goals and the enhancement of shareholder value.
As part of the said review, the Company decided to issue rights to the Directors (excluding the Outside Directors) and Corporate Officers to subscribe for new shares as stock option for stock-linked remuneration.

2. Outline of the issuance of subscription rights to new shares

(1) Name of subscription rights to new shares
The Third Subscription Rights for New Shares (as Stock-Linked Remuneration)
(2) Grantees of the allotment of subscription rights for new shares and number thereof
Two (2) Directors (excluding the Outside Directors) and ten (10) Corporate Officers of the
Company.
(3) Class and number of shares to be issued for subscription rights for new shares
141,800 shares of common stock of the Company (consisting of 30,400 shares for the
Directors, and 111,400 shares for the Corporate Officers)
In the event the Company conducts a split or consolidation of the shares, the number of shares to be issued shall be adjusted in accordance with the formula shown below. However, the adjustment shall be made only to the number of shares to be issued for subscription rights to new shares that have not yet been issued upon the exercise of
subscription rights to new shares at the time of the split or consolidation of the shares, and

any fraction of a share that is less than one (1) share arising out of such adjustment shall be disregarded. Upon the occurrence of any event other than those described above where it is appropriate to change the number of shares to be issued, the Company may adjust the said number to the extent it is reasonable by a resolution of the Board of
Directors.

Officers)
The number of shares of common stock to be issued for one (1) right to subscribe for new shares shall be 100 shares.
The aforesaid number represents the scheduled number of shares to be allotted, and in the event the aggregate number of subscription rights to new shares decreases including cases where no offer for subscription is made, the aggregate number of subscription rights to new shares to be allotted shall be the aggregate number of subscription rights to new shares to be issued. If the adjustment described in subsection (3) above is made, then the number of shares to be issued for subscription rights to new shares shall also be adjusted accordingly.
(5) Method of calculation of the issue price for subscription rights to new shares
The issue price shall be calculated as of the allotment date of subscription rights to new shares based on the Black-Scholes model, which is one of the methods of fairly assessing subscription rights to new shares. However, in lieu of the monetary payment, the grantee of the allotment shall set off the claim for remuneration held by him against the Company with his obligation to pay for his right to subscribe for new shares as of the allotment date of subscription rights to new shares.
The method of calculation using the Black-Scholes model is as described below:

However,

(vi) Risk-free interest rate (r): Interest rate of national government bonds, the remaining years to maturity of which correspond to the expected remaining period
(vii) Prospective dividend yield (q): Dividend per share (actual amount of the dividend paid as at the six month period ended September 30,2014 and the end of the fiscal year ended March 31,2015) divided by the stock price stated in item (ii) above
