Chuo Mitsui Trust Group and The Sumitomo Trust and Banking Group

Towards Creation of “The Trust Bank” with a Combination of Expertise and Comprehensive Capabilities

Chuo Mitsui Trust Holdings, Inc. (“CMTH”; President: Kazuo Tanabe) and The Sumitomo Trust and Banking Co., Ltd. (“STB”; President: Hitoshi Tsunekage) have had repeated discussions on the Management Integration (the “Management Integration”) of their two groups, based on the Basic Agreement that was concluded on November 6, 2009. CMTH and STB hereby announce today, that their boards of directors have resolved the final agreement on a statutory share exchange agreement (the “Share Exchange Agreement”) and a management integration agreement as further explained in detail below. The Management Integration is subject to the approval of the extraordinary general meetings of both CMTH and STB shareholders, and the approval of the relevant authorities.

1. Objectives of the Management Integration

As described in the announcement on November 6, 2009 of “Conclusion of a Basic Agreement on the Management Integration of Chuo Mitsui Trust Group and The Sumitomo Trust and Banking Group”, CMTH and STB have agreed to form “The Trust Bank”, a new trust bank group that, with a combination of significant expertise and comprehensive capabilities, will provide better and swifter comprehensive solutions to their clients than ever before, by combining their personnel, know-how and other managerial resources and fusing both groups’ strengths such as CMTH group’s agility and STB group’s diversity.

2. Management Integration Overview

(1) Method of the Management Integration

The management integration will be accomplished through a holding company structure. In order to expedite the management integration, CMTH will act as the holding company (the “Integrated Holding Company”) for the new trust bank group (the “Sumitomo Mitsui Trust Group”).

CMTH and STB will conduct the Management Integration through a statutory share exchange (the “Share Exchange”) between CMTH and STB and will position CMTH as the Integrated Holding Company. At the same time as the Share Exchange is consummated, CMTH will change its corporate name to Sumitomo Mitsui Trust Holdings, Inc. (“SMTH”) as set out in the section 5 (the “First Step”).

In addition, following the Share Exchange, SMTH will integrate its trust banking subsidiaries through merger (the “Second Step”). See section 8 for further details.

3. Basis of Analysis for Allotment for the Share Exchange

(1) Common Shares

(i) Basis for Financial Analyses

In order to support the respective efforts of CMTH and STB to ensure the fairness of the exchange ratio of common shares (the “Common Share Exchange Ratio”), CMTH has appointed JPMorgan Securities Japan Co., Ltd. (“J.P. Morgan”) and Nomura Securities Co., Ltd. (“Nomura Securities”) as its financial advisors, and STB has appointed UBS Securities Japan Ltd (“UBS”) and Daiwa Securities Capital Markets Co. Ltd. (“Daiwa”) as its financial advisors, all of which are independent from CMTH and STB.

See Exhibit 1 “Overview of the Financial Analyses regarding the Allotment in Share Exchange” for an overview of the financial analyses relating to the Common Share Exchange Ratio performed by J.P. Morgan, Nomura Securities, UBS and Daiwa.

(ii) Background of Financial Analyses

CMTH and STB, on several occasions, conducted careful negotiations and discussions on the Common Share Exchange Ratio, comprehensively taking into account factors such as the financial position, assets and future prospects of each party, with CMTH making reference to the financial analyses prepared by J.P. Morgan and Nomura Securities, and STB to the financial analyses prepared by UBS and Daiwa. As a result of such negotiations and discussions, CMTH and STB concluded today that the Common Share Exchange Ratio set out in the Section 2. (3) is appropriate and agreed on the Common Share Exchange Ratio.

(iii) Relationship with its Financial Advisors

None of J.P. Morgan, Nomura Securities, UBS or Daiwa constitutes a related party of either CMTH or STB, and none of them has a material interest in the Share Exchange.

(iv) Prospects and Reasons for Delisting

As a result of the Share Exchange, STB will become a wholly owned subsidiary of SMTH as of April 1, 2011, and in accordance with the delisting standards of the relevant stock exchanges, the shares of common stock of STB are expected to be delisted on March 29, 2011.

(v) Measures to Ensure Fairness

In order to ensure that the Common Share Exchange Ratio in the Share Exchange is fair, CMTH and STB have each appointed independent financial advisors to perform financial analyses and issue reports relating to the Common Share Exchange Ratio and have each received reports from each of its financial advisors on their financial analyses.

CMTH received written opinions (so-called “fairness opinions”) from J.P. Morgan and Nomura Securities dated August 23, 2010 to the effect that, as of such date, based upon and subject to various assumptions described in Exhibit 1 and certain other assumptions, the agreed upon Common Share Exchange Ratio was fair, from a financial point of view, to CMTH or CMTH’s common shareholders. STB received written opinions (so-called “fairness opinions”) from UBS dated August 24, 2010, and from Daiwa dated August 23, 2010 to the effect that, as of such date, based upon and subject to various assumptions described in Exhibit 1 and certain other assumptions, the agreed upon Common Share Exchange Ratio was fair, from a financial point of view, to STB’s common shareholders.

3

(vi) Measures to Avoid Conflicts of Interest

No measure has been taken to avoid conflicts of interest since there is no conflict regarding the Share Exchange as no person serves as a director or employee of both CMTH and STB.

(2) Preferred Shares

CMTH and STB have agreed that the terms and conditions of the First Series of SMTH Class VII Preferred Shares shall be substantially the same as those of the First Series of STB Class II Preferred Shares, and that 1 share of the First Series of SMTH Class VII Preferred Shares shall be allotted for each share of the First Series of STB Class II Preferred Shares, since no market price exists for the First Series of STB Class II Preferred Shares and such STB Preferred Shares are so-called “bond-type”.

Morgan assumed that they were reasonably prepared based on assumptions reflecting the best available estimates and judgments as of the date of its opinion by management as to the expected future results of operations and financial condition of CMTH and STB to which such analyses or forecasts relate. J.P. Morgan expressed no view as to such analyses or forecasts or the assumptions on which they were based.

The analyses and opinion provided by J.P. Morgan was necessarily based on economic, market and other conditions as in effect on, and the information made available to J.P. Morgan as of August 23, 2010. It should be understood that subsequent developments may affect such analyses and opinion and that J.P. Morgan does not have any obligation to update, revise, or reaffirm such analyses and opinion. The written opinion was limited to the fairness, from a financial point of view, to CMTH of the Common Share Exchange Ratio in the proposed Share Exchange and J.P. Morgan expressed no opinion as to the fairness of the Share Exchange to the holders of any class of securities, creditors or other constituencies of CMTH or as to the underlying decision by CMTH to engage in the Share Exchange. J.P. Morgan expressed no opinion as to the price at which common stock of Sumitomo Mitsui Trust Holdings, Inc. will trade at any future time.

13

Supplementary explanation was provided by J.P. Morgan regarding assumptions and disclaimers for its analyses and opinion. Please see (Note 1) below for more detail.

(Note 1)

J.P. Morgan also assumed that the Share Exchange and the other transactions contemplated by the agreement which includes various terms of the Management Integration (the “Agreement”) would qualify as a tax-free reorganization for Japanese income tax purposes, and would be consummated as described in the Agreement, and that the definitive Agreement would not differ in any material respects from the draft thereof furnished to J.P. Morgan. J.P. Morgan also assumed that the representations and warranties made by CMTH and STB in the Agreement and any related agreements were and would be true and correct in all respects material to its analysis, and that CMTH would have no exposure under any indemnification obligations contained within the Agreement or any related agreements in any amount material to its analysis. J.P. Morgan is not a legal, regulatory or tax expert and relied on the assessments made by advisors to CMTH with respect to such issues. J.P. Morgan further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Share Exchange would be obtained without any adverse effect on CMTH or STB or on the contemplated benefits of the Share Exchange.

The projections for CMTH and STB furnished to J.P. Morgan by CMTH were prepared by the managements of CMTH and STB. Neither CMTH nor STB publicly discloses internal management projections of the type provided to J.P. Morgan in connection with J.P. Morgan’s analysis of the Share Exchange, and such projections were not prepared with a view toward public disclosure. These projections were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of management, including, without limitation, factors related to general economic and competitive conditions and prevailing interest rates. Accordingly, actual results could vary significantly from those set forth in such projections. Furthermore, J.P. Morgan expressed no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the Share Exchange, or any class of such persons relative to the Common Share Exchange Ratio in the Share Exchange or with respect to the fairness of any such compensation.

The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by J.P. Morgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. J.P. Morgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and its opinion. In arriving at its opinion, J.P. Morgan did not attribute any particular weight to any analyses or factors considered by it and did not form a view as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, J.P. Morgan considered the totality of the factors and analyses performed in determining its opinion. Analyses based upon forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses used or made by J.P. Morgan are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. Moreover, J.P. Morgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be bought or sold.

J.P. Morgan acted as financial advisor to CMTH with respect to the proposed Share Exchange and will receive a fee from CMTH for its services, a substantial portion of which will become payable only if the proposed Share Exchange is consummated. In addition, CMTH agreed to reimburse J.P. Morgan for its expenses incurred in connection with its services, including the fees and disbursements of counsel, and will indemnify J.P. Morgan against certain liabilities arising out of its engagement. During the two years preceding the date of the written opinion, J.P. Morgan and its affiliates have had commercial or investment banking relationships with CMTH and its affiliates for which J.P. Morgan and such affiliates have received customary compensation. In such period, J.P. Morgan acted as agent to The Chuo Mitsui Trust and Banking Company, Limited with respect to its buyback of perpetual subordinated debt obligations, and have entered into various derivatives transactions with CMTH and STB. In addition, commercial banking affiliates of J.P. Morgan receive customary compensation or other financial benefits from CMTH or from STB for treasury services. In the ordinary course of businesses of J.P. Morgan, J.P. Morgan and its affiliates may actively trade the debt and equity securities of CMTH or STB for its own account or for the accounts of customers and, accordingly, J.P. Morgan may at any time hold long or short positions in such securities.

Nomura Securities performed average market price analysis, comparable peer company analysis, dividend discount model analysis (“DDM Analysis”) and contribution analysis calculations with respect to CMTH and STB. The calculation results based on each analysis are briefly summarized as follows. The calculated ranges of the Common Share Exchange Ratio provided below show the ranges of the number of shares of SMTH common stock that are to be allotted for each share of STB common stock.

For the average market price analysis, Nomura Securities made calculations based on the closing stock price on August 17, 2010 (the “Reference Date”), the average closing stock prices for the five (5) business days from August 11, 2010 up to the Reference Date, the average closing stock prices for the twelve (12) business days from August 2, 2010 (after each of CMTH and STB released its financial results for the 1st Quarter of Fiscal Year 2010) up to the Reference Date, the average closing stock prices for the one month from July 20, 2010 up to the Reference Date, the average closing stock prices for the three (3) months from May 18, 2010 up to the Reference Date, and the average closing stock prices for the six (6) months from February 18, 2010 up to the Reference Date.

	Analysis Method	Calculated Range of Common Share  Exchange Ratio
1	Average Market Price Analysis	1.48 ~ 1.53
2	Comparable Peer Company Analysis	1.21 ~ 1.59
3	DDM Analysis	1.38 ~ 1.58
4	Contribution Analysis	1.12 ~ 1.68

In performing its analysis, Nomura Securities used information provided by CMTH as well as publicly available information. Nomura Securities has assumed that all such materials and information are accurate and complete and has not conducted any independent verification of their accuracy and completeness. In addition, Nomura Securities has not conducted any independent evaluation, appraisal or assessment of the assets or liabilities (including contingent liabilities) of either CMTH or STB, including analysis and evaluation of individual assets and liabilities, or appointed any third party for appraisal or assessment. Nomura Securities’ Common Share Exchange Ratio calculations reflect information and economic conditions as of August 23, 2010, and Nomura Securities has assumed that the financial forecasts (including profit plans and other information) provided by CMTH and STB to Nomura Securities have been reasonably prepared by the managements of each of CMTH and STB on a basis reflecting the best currently available estimates and judgments of CMTH and STB.

Nomura Securities rendered its opinion to CMTH, dated August 23, 2010, stating that from a financial point of view, the agreed upon number of shares of CMTH common stock to be allotted for each share of STB common stock is fair to the holders of CMTH common stock, subject to the conditions set forth above and certain other conditions.

UBS, as part of the process of preparing its written opinion referred to below, performed an analysis of historical trading ratios, an analysis of selected publicly traded Japanese major banks, a contribution analysis and a discounted cashflow (“DCF”) analysis. In its historical trading ratio analysis, UBS derived the ratio for the historical share price of STB to the historical share price of CMTH (“historical trading ratio”) based on the closing share price of each company on August 17, 2010 (the “Base Date”), which is one day prior to a press leak about the proposed exchange ratio, and the average daily closing share prices of each company for the one-week, one-month, three-month and six-month periods up to and including the Base Date. In its DCF analysis, UBS calculated a range of implied equity values for CMTH, for STB, and for the synergies projected to result from the Management Integration. Among other information that UBS derived from its DCF analysis, UBS derived a range of implied Common Share Exchange Ratio (“Implied Exchange Ratios”) using these implied equity values. The DCF analysis was conducted based on projections of future cash flow, calculated as net income to common stock plus capital adjustments to maintain required capital, using financial forecasts and estimates prepared by the managements of both CMTH and STB that UBS was directed to use by the board of directors of STB (the “STB Board”). A summary of the historical trading ratio analysis is presented in the table below, together with the range of Implied Exchange Ratios derived from the DCF analysis. Although UBS considered all of the analyses it performed, UBS did not derive a range of Implied Exchange Ratios based on the analysis of selected publicly traded Japanese major banks or the contribution analysis.

Analysis Method	Range of Historical Trading Ratios / Range of Implied Exchange Ratios
Historical Trading Ratio Analysis
Base Date	1.48
1week	1.50
1 month	1.52
3 month	1.49

UBS delivered to the STB Board a written opinion (“UBS’s Opinion”) that, as of August 24, 2010, and based upon and subject to various significant assumptions, disclaimers, matters considered and limitations described in UBS’s Opinion, including the assumptions, limitations and disclaimers described in “Note 2” below, the Common Share Exchange Ratio agreed upon in the Share Exchange Agreement was fair, from a financial point of view, to the holders of STB common shares. UBS provided its advisory services and UBS’s Opinion for the information and assistance of the STB Board in connection with its consideration of the Share Exchange and UBS’s Opinion does not constitute a recommendation as to how any holder of STB common shares should vote with respect to the Share Exchange or any other matter. UBS did not recommend any particular Common Share Exchange Ratio to STB or the STB Board as the only appropriate Common Share Exchange Ratio.

UBS’s analyses and opinion are necessarily based on economic, financial, market and other conditions as in effect on, and the information made available to UBS as of, August 24, 2010, and UBS assumes no responsibility for updating, revising or reaffirming its analyses or opinion based on circumstances, developments or events occurring after the date thereof. With respect to the financial forecasts, estimates and synergies prepared by CMTH and STB which were provided to UBS and which the STB Board directed UBS to use for purposes of its analyses, UBS assumed, at the direction of the STB Board, that such financial forecasts, estimates and synergies were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of CMTH and STB. In addition, UBS assumed, with the approval of the STB Board, that such financial forecasts and estimates, including synergies, would be achieved at the times and in the amounts projected.

(Note 2)

UBS has acted as financial advisor to STB in connection with the Management Integration. UBS will receive a fee for its services, a portion of which is contingent upon consummation of the Share Exchange and a further portion of which is contingent upon the consummation of a merger of STB, Chuo Mitsui Asset Trust and Banking Company, Limited and The Chuo Mitsui Trust and Banking Company, Limited. STB has also agreed to indemnify UBS for certain liabilities arising out of its engagement. In the past, UBS and its affiliates have provided investment banking services to CMTH and STB and their respective affiliates unrelated to the proposed Management Integration, for which UBS and its affiliates received compensation, including having acted as a financial advisor to STB on (i) the merger between Sumitomo Trust Leasing Co., Ltd, a wholly owned subsidiary of STB, and Sumishin Panasonic Financial Services Co., Ltd., and (ii) STB’s acquisition of Nikko Asset Management Co., Ltd. In the ordinary course of business, UBS and its affiliates may hold or trade, for their own accounts and the accounts of their customers, securities of CMTH and STB and their respective affiliates and, accordingly, may at any time hold a long or short position in such securities. The issuance of UBS’s Opinion was approved by authorized committees of UBS and UBS Securities LLC.

The foregoing summary is not a complete description of all analyses performed and factors considered by UBS in connection with UBS’s Opinion. The preparation of a financial opinion is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description. UBS believes that its analyses, a portion of which are summarized above, must be considered as a whole and that selecting portions of its analyses or focusing on information presented in tabular format could create an incomplete view of the processes underlying UBS’ analyses and opinion. UBS did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis for purposes of its opinion, but rather arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole.

UBS’s Opinion did not address the relative merits of the Management Integration or any related transaction as compared to other business strategies or transactions that might be available to STB or STB’s underlying business decision to effect the Management Integration or any related transaction. The STB Board did not ask UBS to, nor did UBS, offer any opinion (i) as to the terms, other than the Common Share Exchange Ratio to the extent expressly specified in UBS’ Opinion, of the Share Exchange Agreements or the form of the Management Integration or any related transaction, or (ii) as to the fairness to, or any other consideration to, the holders of any class of securities, creditors or other constituencies of STB, other than the holders of STB common shares. In addition, UBS expressed no opinion as to the fairness of the amount or nature of any compensation to be received by any officers, directors or employees of any parties to the Management Integration, or any class of such persons, relative to the Common Share Exchange Ratio. UBS expressed no opinion as to the price at which STB common shares would trade following the announcement of the Agreements or what the value of SMTH common shares would be when issued pursuant to the Share Exchange or the price at which CMTH common shares, STB common shares or SMTH common shares would trade at any time. In rendering UBS’s Opinion, UBS assumed, with the consent of STB, that (i) the final executed form of the Share Exchange Agreement would not differ in any material respect from the draft that UBS reviewed, (ii) the parties to the Agreements would comply with all material terms of the Agreements, and (iii) the Management Integration would be consummated in accordance with the terms of the Agreements without any adverse waiver or amendment of any material term or condition thereof. UBS also assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Management Integration would be obtained without any material adverse effect on CMTH, STB or the Management Integration. UBS was not authorized to solicit and did not solicit indications of interest in a transaction with STB from any third party.

In connection with the review of UBS, with the consent of the STB Board, UBS assumed and relied upon, without independent verification, the accuracy and completeness in all material respects of the information provided to or reviewed by UBS for the purpose of UBS’s opinion. In addition, with the consent of the STB Board, UBS did not make any independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of STB and CMTH, nor was UBS furnished with any such evaluation or appraisal. UBS is not an expert in the evaluation of individual financial assets, such as loan or lease portfolios or allowances for losses with respect thereto, and was not requested to conduct, and did not conduct, a review of individual credit files, and have been advised and therefore have assumed that such allowances for CMTH and STB are, and on a pro forma basis will be, in the aggregate appropriate to cover such losses.

UBS’s Opinion was based upon financial information prepared in accordance with generally accepted accounting principles in Japan (“Japan GAAP”). UBS did not review any financial information prepared by STB or CMTH in accordance with International Financial Reporting Standards (“IFRS”) for the purpose of UBS’s analyses and did not take account of any differences between Japan GAAP and IFRS in its analyses. UBS also assumed, with the consent of STB, that the Share Exchange would qualify as a tax-free reorganization for Japanese income tax and Japanese corporate tax purposes. UBS’s Opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information available to UBS as of, the date of UBS’s Opinion.

Daiwa performed a stock price analysis and a discounted cash flow (“DCF”) analysis. The results of the analyses are shown in the table below. Each of the Common Share Exchange Ratio ranges represents the range of the number of shares of SMTH common stock that are to be allotted for each share of STB common stock, based on the result of the relevant analysis.

In performing the stock price analysis, Daiwa set August 17th, 2010 as a reference date, and used the closing share prices as of the reference date and the average daily closing prices for the one-month, three-month and six-month periods ending on the reference date.

Analysis Method	Range of STB Common Share Exchange Ratios
1. Stock Price Analysis	1.48 ~ 1.53
Reference date	1.48
1 month before the reference date	1.52
3 months before the reference date	1.49
6 months before the reference date	1.53
2. DCF Analysis	1.36 ~ 1.55

In performing its analyses, Daiwa assumed and relied on the accuracy and completeness of all information that Daiwa reviewed or analyzed, and did not verify or assume any obligation to independently verify the accuracy or completeness of such information. Daiwa did not undertake a separate evaluation, appraisal or assessment of any of the assets or liabilities, on an aggregate or individual basis, of STB or CMTH and their respective affiliates (including, but not limited to, financial derivative products, off-balance-sheet assets and liabilities and other contingent liabilities), nor did Daiwa make any request to a third party for any such valuation, appraisal or assessment. Daiwa assumed that the business plans, financial forecasts and other information furnished to Daiwa by STB and CMTH were prepared according to reasonable procedures, and reflect the best currently available estimates and judgment of the management of STB and CMTH respectively, and, with STB’s consent, Daiwa relied on such information without independent verification. Daiwa’s analyses were based upon financial, economic, market and other conditions as they existed as of August 23, 2010, and relied on information made available to Daiwa by such date.

Daiwa delivered a written opinion to the board of directors of STB, dated August 23, 2010, stating that, as of such date, the Common Share Exchange Ratio was fair, from a financial point of view, to the holders of STB common stock, subject to the conditions set forth above and certain other conditions.
