Calculation of Filing Fee

Transaction Valuation*	Amount of Filing Fee**
$3,662,196,226.50	$143,924.31

* Estimated for purposes of calculating the filing fee only. This calculation assumes the purchase of all outstanding shares of common stock, par value $1.00 per share (the “Common Stock”), of UnionBanCal Corporation, a Delaware corporation, other than shares of Common Stock owned by Mitsubishi UFJ Financial Group, Inc. (“MUFG”) and its subsidiaries (but including such shares of Common Stock that are held in a fiduciary capacity), at the tender offer price of $73.50 per share of Common Stock, net to the seller in cash. As of August 14, 2008, there were 139,009,259 shares of Common Stock outstanding. As of August 14, 2008, MUFG owned 90,259,680 shares of Common Stock indirectly through its subsidiaries as follows: 90,217,308 shares by The Bank of Tokyo Mitsubishi UFJ, Ltd.; 30,272 shares by Mitsubishi UFJ Trust and Banking Corporation (held in a fiduciary capacity); and 12,100 shares by Mitsubishi UFJ Asset Management Co., Ltd. (held in a fiduciary capacity). Subsequent to August 14, 2008, UnionBanCal Corporation issued an additional 1,033,848 shares of Common Stock pursuant to the exercise of compensatory stock options. Therefore, the amount of the filing fee was increased in Amendment No. 3 to this Schedule 13E-3 by $2,986.32 to account for such increase in outstanding shares and resulting increase in transaction value. As a result, this calculation assumed the purchase of 48,825,799 shares of Common Stock.

** The amount of the filing fee, calculated in accordance with Rule 0-11 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Fee Rate Advisory No. 6 for fiscal year 2008 issued by the Securities and Exchange Commission on December 27, 2007, equals 0.00393% of the transaction value.

x Check box if any part of the fee is offset as provided by Exchange Act Rule 0-11(a) (2) and identify the filing with which the offsetting fee was previously paid. Identify the previous filing by registration statement number, or the Form or Schedule and date of its filing.

Amount Previously Paid: $143,924.31	Filing Party: The Bank of Tokyo-Mitsubishi UFJ, Ltd.
Form or Registration No.: Schedule TO, as amended	Dates Filed: August 29, 2008; October 3, 2008

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THIS TRANSACTION, PASSED UPON THE MERITS OR FAIRNESS OF THIS TRANSACTION, OR PASSED UPON THE ADEQUACY OR ACCURACY OF THE DISCLOSURE IN THIS SCHEDULE 13E-3.

This Amendment No. 4 (this “Amendment”) amends and supplements certain portions of the Schedule 13E-3 Transaction Statement initially filed with the Securities and Exchange Commission (the “SEC”) on August 29, 2008 under cover of Schedule TO, as amended by Amendment No. 1 thereto filed with the SEC on September 19, 2008, Amendment No. 2 thereto filed with the SEC on September 29, 2008 and Amendment No. 3 thereto filed with the SEC on October 3, 2008 (as amended, the “Schedule 13E-3” or “Transaction Statement”)), on behalf of The Bank of Tokyo-Mitsubishi UFJ, Ltd. (“Purchaser” or “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”), relating to the offer (the “Offer”) by Purchaser to purchase all of the outstanding shares of common stock, par value $1.00 per share (the “Shares”), of UnionBanCal Corporation, a Delaware corporation (the “Company”), other than those shares held by MUFG or one of its subsidiaries (other than the Company and its subsidiaries) in a proprietary (rather than a fiduciary or bailee) capacity, for $73.50 per Share, net to the seller in cash without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated August 29, 2008 (the “Offer to Purchase”), and in the related Letter of Transmittal, dated August 29, 2008, as amended and supplemented by the Supplement, dated September 19, 2008, to the Offer to Purchase. Capitalized terms used but not otherwise defined in this Amendment shall have the meanings ascribed to them in the Schedule 13E-3.

This Transaction Statement also relates to the Agreement and Plan of Merger, dated as of August 18, 2008, by and among the Company, Purchaser and Blue Jackets, Inc., a Delaware corporation and a wholly owned subsidiary of Purchaser (“Merger Sub”) (as such agreement may be amended or supplemented from time to time, the “Merger Agreement”). The Merger Agreement provides, among other things, for the making of the Offer by Purchaser and further provides that, upon the terms and subject to the conditions contained in the Merger Agreement, as soon as reasonably practicable, and in any event within three business days after the satisfaction or waiver of the conditions set forth in the Merger Agreement, and subject to and upon the terms and conditions of the Merger Agreement and the Delaware General Corporation Law, Merger Sub will merge with and into the Company (the “Merger”), the separate corporate existence of Merger Sub shall thereupon cease and the Company shall continue as the surviving corporation in the Merger. Upon completion of the Merger, all shares of Common Stock issued and outstanding immediately prior to the closing of the Merger, other than such shares of Common Stock owned by the Company, by MUFG or its affiliates, or by holders of Common Stock who have perfected appraisal rights, will be converted into the right to receive an amount in cash equal to the Offer Price (the “Merger Consideration”).

The Company has filed a definitive Schedule 14C Information Statement (as amended from time to time, the “Information Statement”) under Regulation 14C of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), relating to the action by written consent of the holders of over 90% of the Shares approving and adopting the Merger Agreement and approving the Merger.
