Item 2.01 Completion of Acquisition or Disposition of Assets.

Effective as of November 4, 2008, The Bank of Tokyo-Mitsubishi UFJ, Ltd. (“BTMU”), a joint stock company (kabushiki kaisha) incorporated in Japan under the Commercial Code of Japan and a wholly-owned subsidiary of Mitsubishi UFJ Financial Group, Inc., a joint stock company (kabushiki kaisha) incorporated in Japan under the Commercial Code of Japan (“MUFG”), completed its previously announced merger transaction with UnionBanCal Corporation, a Delaware corporation (the “Company”), pursuant to which the Company became a wholly owned subsidiary of MUFG, pursuant to the Agreement and Plan of Merger, dated as of August 18, 2008, by and among the Company, BTMU and Blue Jackets, Inc. (“Merger Sub”), a Delaware corporation and a wholly-owned subsidiary of BTMU (as such agreement may be amended or supplemented from time to time, the “Merger Agreement”). On November 4, 2008, pursuant to the terms of the Merger Agreement, Merger Sub merged with and into the Company (the “Merger”), with the Company as the surviving corporation (the “Surviving Corporation”) and a wholly-owned indirect subsidiary of MUFG. In the Merger, all outstanding shares of common stock, par value $1.00 per share (the “Shares”), issued and outstanding immediately prior to the effective time of the Merger (the “Effective Time”), other than such Shares owned by the Company, by MUFG or its affiliates, or by holders of Shares who have perfected appraisal rights, were cancelled and converted into the right to receive $73.50.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Merger Agreement, which is attached as Exhibit 2.1 of the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) by the Company on August 19, 2008 (SEC File No. 001-15081), and is incorporated herein by reference thereto.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

In connection with the closing of the Merger, the Company notified the New York Stock Exchange (the “NYSE”) of the Company’s intent to remove the Shares from listing, and the Company expects the NYSE promptly to file with the Securities and Exchange Commission (the “SEC”) a Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on Form 25, thereby effecting the delisting of the Shares from the NYSE.
