Notice regarding revisions to basic agreement on proposed share exchange to make Mitsubishi

UFJ Securities a wholly-owned subsidiary of MUFG

Tokyo, November 20, 2006 — Mitsubishi UFJ Financial Group, Inc. (MUFG) and Mitsubishi UFJ Securities Co., Ltd. (MUS) announced today a change in the schedule as described below with respect to the proposed share exchange agreement previously announced on August 29, 2006 to make MUS a wholly-owned subsidiary of MUFG, which agreement is subject to approval by MUS shareholders and the relevant authorities.

There are no other changes to the transaction from the previously announced press release of August 29, 2006.

The share exchange will not affect MUFG’s earnings forecast for the fiscal year ending March 31, 2007, announced today.

1. Tentative Schedule to Make MUS a Wholly-Owned Subsidiary of MUFG

	Previously announced schedule	Revised schedule
Board meetings to approve share exchange agreement	Middle of November 2006	Late March 2007
Signing of share exchange agreement	Middle of November 2006	Late March 2007
General shareholders’ meeting to approve share exchange agreement (MUS)	Late February 2007	Late June 2007 (regular annual shareholders meeting)
Effective date of share exchange	March 31, 2007	September 30, 2007

(Note) MUFG will conduct this share exchange transaction without obtaining shareholder approval at its general shareholders’ meeting, since this share exchange transaction is deemed a “simple share exchange” under Article 796-3 of the Company Law of Japan.

2. Reasons for Schedule Change

In recent years, the evolving global regulatory environment has required companies to strengthen their internal controls as evidenced by the Sarbanes-Oxley Act in the United States and the Financial Instruments and Exchange Law in Japan. Accordingly, the strengthening of internal controls is currently one of the main focus areas for MUFG’s management. As a NYSE-listed company that will be required to disclose management’s assessment relating to the effectiveness of its internal controls over financial reporting, MUFG is aiming to establish effective internal controls over financial reporting for the fiscal year ending March 31, 2007. The SEC filing relating to the proposed share exchange agreement to make MUS a wholly-owned subsidiary of MUFG will include U.S. GAAP financial information. The change in the schedule is intended to ensure that such U.S. GAAP financial information has been properly prepared.
