MITSUBISHI UFJ FINANCIAL GROUP AND THE BANK OF TOKYO-MITSUBISHI UFJ COMPLETE TENDER OFFER FOR UNIONBANCAL

Tokyo, September 29, 2008 – Mitsubishi UFJ Financial Group, Inc. (“MUFG”) and its wholly owned subsidiary, The Bank of Tokyo-Mitsubishi UFJ, Ltd. (“BTMU”) today announced the successful completion of the cash tender offer by MUFG and BTMU to purchase all of the outstanding shares of UnionBanCal Corporation (“UNBC”) that MUFG and its affiliates do not already own. The offer expired at 12:00 midnight EDT on Friday, September 26, 2008.

As of the close of the offer, approximately 41,736,256 UNBC shares had been validly tendered, and not properly withdrawn, representing approximately 29.8% of the outstanding shares of UNBC. When added to MUFG’s and its affiliates’ existing 64.4% stake, this represents approximately 94.2% of UNBC’s total outstanding shares. In addition, a further 3.8% of UNBC’s outstanding shares were guaranteed to be delivered within the next three business days which, if added to the tendered shares and MUFG’s existing stake, would represent approximately 98.0% of UNBC’s total outstanding shares. All shareholders who have tendered shares will promptly receive $73.50 per share in cash.

In accordance with the merger agreement between BTMU and UNBC announced on August 18, 2008, BTMU and UNBC will carry out a second-step merger as a result of which UNBC will become a wholly owned indirect subsidiary of MUFG. In the merger, each share of UNBC common stock not previously purchased in the tender offer will be converted, subject to appraisal rights, into the right to receive $73.50 per share in cash. Consummation of the merger is expected to occur as soon as reasonably practicable.
