Announcement regarding Issuance of Stock Acquisition Rights as Stock Options

May 18, 2005—At a meeting held today, the Board of Directors of Mitsubishi Securities Co., Ltd. (the “Company”) resolved to submit to the annual general meeting of the shareholders to be held on June 29, 2005 an agenda item seeking the approval of the issuance of the stock acquisition rights in accordance with Article 280-20 and Article 280-21 of the Commercial Code of Japan.

1. Reasons for issuing Stock Acquisition Rights on Specially Favorable Conditions

Following the merger of the Company and UFJ Tsubasa Securities Co., Ltd., the Company will issue the stock acquisition rights for no consideration because of the procedural requirements to protect the actual economic value of the stock options based on the stock subscription rights method (hereinafter referred to as the “previous stock subscription rights”) granted by UFJ Tsubasa Securities, the dissolving entity (hereinafter referred to as the “dissolving entity”), to employees as of June 29, 2000, in accordance with paragraph 1 of Article 280-19 of the previous commercial code of Japan.

2. Method of Issuance of Stock Acquisition Rights

(1) Recipients of stock acquisition rights

Holders of the previous stock subscription rights and their successors who (1) have not been granted stock acquisition rights of the dissolving entity by the merger date, and (2) hold unexercised stock subscription rights will receive the stock acquisition rights.

(2) Types and number of stocks that are the subject of stock acquisition rights

The maximum limit shall be 2,616,180 ordinary shares of the Company after the merger. The maximum number of shares is obtained by adjusting 6,229,000 shares, which is the number of shares that is the subject of the previous stock subscription rights, by the merger ratio of 0.42.

(3) Total number of stock acquisition rights

The maximum limit shall be 2,616,180. (The number of shares per each stock acquisition right shall be 1 ordinary share.)

(4) Issue price of stock acquisition rights

The stock acquisition rights will be issued for no consideration.

(5) Amount payable upon exercise of the stock acquisition rights

The amount payable upon exercise of each stock acquisition right will be ¥1,412 per share (the “Exercise Price”). The Exercise Price is obtained by adjusting the exercise price of the previous stock subscription right (¥593) in accordance with the following formula:

[Exercise Price after Adjustment]=[Exercise Price before Adjustment]	x	1
		Merger Ratio (0.42)

If the Company issues new shares or divests its treasury stock (excluding any exercise of stock acquisition rights) at a price below the market price after the date on which stock acquisition rights are issued, the Exercise Price shall be adjusted in accordance with the following formula, with factional amounts of less than one yen resulting from such calculation to be rounded up to one yen.

[Exercise Price after Adjustment]	=	[Exercise Price before Adjustment]	x	(Number of Outstanding Shares)	+	(Number of New Shares to be Issued) x (Amount to be paid per share)
						(Market Price per Share before Issue of New Shares)
				(Number of Outstanding Shares) + (Number of New Shares to be Issued)

The “number of outstanding shares” in the price adjustment formula above is obtained by subtracting the total number of treasury stock from the number of outstanding shares. In the event that the Company decides to divest its treasury stock, the “number of new shares to be issued” shall be replaced by the “number of treasury stock to be divested.” In addition, if the Company conducts a stock split or stock consolidation after the Exercise Price is determined, the Company may adjust the Exercise Price as appropriate.

(6) Exercise Period of the Stock Acquisition Rights

The exercise period shall be between the date of issuance of the stock acquisition rights and March 31, 2006 (the end of the exercise period for the previous stock subscription rights).

(7) Conditions to the Exercise of Stock Acquisition Rights

1. If a person granted with the stock acquisition right dies, the successor of such person shall be entitled to exercise the right in accordance with the provisions of the agreement relating to the grant of stock acquisition rights.

2. Other matters relating to the exercise of stock acquisition rights will be determined by the Board of Directors of the Company and will be set forth in the agreement relating to the grant of stock acquisition rights.

(8) Cancellation of Stock Acquisition Rights

1. The Company may cancel all stock acquisition rights for no consideration with the Board of Directors’ resolution if the following matters are approved at the general meeting of shareholders.

(i) Merger agreement, under which the Company becomes the dissolving entity.

(ii) Share exchange agreement, under which the Company becomes a wholly owned subsidiary.

(iii) Share transfer agreement, under which the Company becomes a wholly owned subsidiary.

2. If the subject persons who were granted the stock acquisition rights waive, either in whole or in part, the stock acquisition rights, the Company will be able to cancel the stock acquisition rights for no consideration.

(Note) The above issuance of stock acquisition rights is subject to the approval of “Issuance of Stock Acquisition Rights as Stock Options” at the annual general meeting of shareholders to be held on June 29, 2005. Further details shall be decided by making resolutions at the meeting of the Board of Directors after obtaining the approval of the general meeting of the shareholders.
