RECITALS

WHEREAS, as of the date hereof, Parent and its affiliates beneficially and of record own 90,255,980 shares of common stock, par value $1.00 per share, of the Company (the “Common Stock”), constituting approximately 64.9% of the issued and outstanding shares of Common Stock;

WHEREAS, Parent and Mitsubishi UFJ Financial Group, Inc., a Japanese joint stock corporation and the parent company of Parent (“MUFG”), have proposed to the board of directors of the Company (the “Company Board”) that Parent or one of its wholly owned direct or indirect Subsidiaries acquire all of the shares of Common Stock not held in a proprietary (rather than a fiduciary or bailee) capacity by MUFG or one of its Subsidiaries other than the Company and its Subsidiaries (the “Public Shares”);

WHEREAS, the Company Board has established a special committee (the “Special Committee”) consisting of independent directors to consider, among other things, the Offer, the Merger and the other transactions contemplated by this Agreement (collectively, the “Transactions”) and to make a recommendation to the Company Board with respect thereto;

WHEREAS, the Special Committee has unanimously (with one member absent) (i) determined that the terms of this Agreement and the Transactions are fair to and in the best interests of the Company and the holders of the Public Shares, (ii) approved and declared advisable this Agreement and the Transactions, and (iii) recommended to the Company Board that the Company Board adopt resolutions approving and declaring advisable this Agreement and the Transactions and recommending that the holders of Public Shares accept the Offer, tender their Public Shares to Parent pursuant to the Offer and, to the extent any such holders do not tender their Public Shares, adopt this Agreement (such recommendation by the Special Committee, the “Special Committee Recommendation”);

WHEREAS, the Company Board, based on the Special Committee Recommendation, has (i) determined that the terms of this Agreement and the Transactions are fair to and in the best interests of the Company and the holders of Public

Shares, (ii) approved and declared advisable this Agreement and the Transactions, and (iii) resolved to recommend to the holders of Public Shares that they accept the Offer, tender their Public Shares to Parent pursuant to the Offer and adopt, to the extent any such holders do not tender their Public Shares, this Agreement (such recommendation, the “Company Board Recommendation”);

WHEREAS, the respective boards of directors of each of Parent and Merger Sub have (i) determined that the Transactions are fair to and in the best interests of Parent and Merger Sub, respectively, and (ii) approved and declared advisable this Agreement and the Transactions, in each case to the extent they are a party to such Transactions;

WHEREAS, Parent is willing and intends, on the terms and subject to the conditions set forth in this Agreement, to commence a tender offer (the “Offer”) to purchase all of the outstanding Public Shares, in cash at a price per Public Share of $73.50 (such price or any higher price per Public Share that may be offered to be paid pursuant to the Offer being hereinafter referred to as the “Offer Price”), net to the seller but subject to any required withholding of Taxes;

WHEREAS, following the consummation of the Offer, on the terms and subject to the conditions set forth in this Agreement (including the Company Requisite Vote), Merger Sub will be merged with and into the Company with the Company as the Surviving Corporation (the “Merger”); and

WHEREAS, the Company, Parent and Merger Sub desire to make certain representations, warranties, covenants and agreements in connection with this Agreement.

NOW, THEREFORE, in consideration of the premises, and of the representations, warranties, covenants and agreements contained herein, the parties hereto agree as follows:

ARTICLE I

THE OFFER AND THE MERGER; CLOSING; EFFECTIVE TIME

1.1 The Offer. (a) Subject to the conditions of this Agreement, Parent shall, as promptly as practicable and in no event later than ten business days after the date hereof, commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) the Offer at the Offer Price, net to the seller but subject to any required withholding of Taxes.

(b) The initial expiration date of the Offer shall be midnight (New York City time) on the date that is 20 business days from the date on which the Offer was commenced (determined as provided in Rule 14d-1(g)(3) under the Exchange Act) (the initial “Expiration Date” and any expiration time and date established pursuant to an extension of the Offer as so extended, also an “Expiration Date”).

(c) The obligations of Parent to commence the Offer and accept for payment, and pay for, any Public Shares tendered pursuant to the Offer are subject only to (i) the conditions set forth in Exhibit 1 and (ii) the non-waivable condition that pursuant to the Offer, prior to the Expiration Date, there shall have been validly tendered and not properly withdrawn a number of Public Shares which constitutes at least a majority of the outstanding Public Shares (assuming the exercise of all options, warrants and other rights to purchase shares of Common Stock and excluding from the numerator of such calculation any shares held by stockholders that are affiliated with the Company, including directors and officers of the Company, as of the Acceptance Time) (the “Majority-of-the-Minority Condition”).

(d) Parent expressly reserves the right (x) to increase the Offer Price and (y) to waive any condition to the Offer or modify the terms of the Offer, except that, without the consent of the Company, Parent shall not (i) reduce the number of Public Shares subject to the Offer, (ii) except as provided in Section 4.4, reduce the Offer Price, (iii) add to the conditions set forth in Exhibit 1 or modify any condition set forth in Exhibit 1 in any manner adverse to the holders of Public Shares, (iv) except as otherwise provided in this Section 1.1(d), extend the Offer, (v) waive or modify the Majority-of-the-Minority Condition, or (vi) change the form of consideration payable in the Offer. Notwithstanding the foregoing, Parent may, in its discretion, without the consent of the Company, (i) extend the Offer for one or more consecutive increments of not more than ten business days each, if at any otherwise scheduled Expiration Date of the Offer any of the conditions to Parent’s obligation to purchase Public Shares are not satisfied or waived, (ii) extend the Offer for the minimum period required by any rule, regulation, interpretation or position of the Securities and Exchange Commission (the “SEC”) or the staff thereof applicable to the Offer or (iii) make available a “subsequent offering period” in accordance with Exchange Act Rule 14d-11. In addition, if at any otherwise scheduled Expiration Date of the Offer any condition to the Offer is not satisfied or waived, Parent shall extend the Offer at the request of the Company for one or more consecutive increments of not more than ten business days each until the earlier of the date that is 40 business days after commencement of the Offer (the “Outside Date”) and the termination of this Agreement in accordance with its terms. In addition, Parent shall, if requested by the Company, make available a subsequent offering period in accordance with Exchange Act Rule 14d-11 of not less than ten business days; provided that Parent shall not be required to make available such a subsequent offering period in the event that, prior to the commencement of such subsequent offering period, MUFG and its Subsidiaries collectively hold at least 90% of the outstanding shares of Common Stock (the requirement that MUFG and its Subsidiaries collectively hold at least 90% of the outstanding shares of Common Stock being the “90% Requirement”).

(e) On the terms and subject to the conditions of the Offer and this Agreement, Parent shall accept and pay for all Public Shares validly tendered and not withdrawn pursuant to the Offer that Parent becomes obligated to purchase pursuant to the Offer as soon as practicable after the expiration of the Offer.

For purposes of this Agreement, the term “business day” shall have the meaning assigned to such term in Rule 14d-1(g)(3) under the Exchange Act.

1.2 The Offer Documents. On the date of commencement of the Offer, Parent and, to the extent required by Law, its affiliates shall file with the SEC, pursuant to and in accordance with Rule 14d-3 and Regulation M-A under the Exchange Act (“Regulation M-A”), a Tender Offer Statement on Schedule TO with respect to the Offer, which shall contain an offer to purchase and a related letter of transmittal and summary advertisement (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the “Offer Documents”) and shall cause the Offer Documents to be disseminated to holders of Public Shares as and to the extent required by the applicable federal securities laws, including for the avoidance of doubt the Xxxxxxxx-Xxxxx Act of 2002, as amended (the “Xxxxxxxx-Xxxxx Act”), and the rules and regulations of the SEC thereunder (collectively, the “Securities Laws”). Prior to the filing of the Offer Documents with the SEC, Parent shall deliver copies of the proposed form of the Offer Documents to the Company and the Special Committee, and their respective counsel, within a reasonable time for review and comment by the Company and the Special Committee, and their respective counsel. Each of Parent and the Company agrees to use reasonable best efforts to respond promptly to any comments of the SEC or its staff with respect to the Offer Documents or the Offer and to promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information shall become false or misleading in any material respect or as otherwise required by the Securities Laws. Parent shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents, as so amended or supplemented, to be filed with the SEC and to be disseminated to the holders of Public Shares, in each case as and to the extent required by the Securities Laws. The Company and the Special Committee, and their respective counsel, shall be given reasonable opportunity under the circumstances to review and comment on the Offer Documents (including any amendments or supplements thereto) before they are filed with the SEC or disseminated to the stockholders of the Company. Parent shall provide the Company and the Special Committee, and their respective counsel, with copies of any written comments, and shall inform them of any oral comments, that Parent or its counsel receives from the SEC or its staff with respect to the Offer Documents promptly after the receipt of such comments and shall give the Company and the Special Committee, and their respective counsel, a reasonable opportunity under the circumstances to review and comment on any written or oral responses to such comments. The Company hereby consents to the inclusion in the Offer Documents of the Special Committee Recommendation and the Company Board Recommendation, as such recommendations may be amended and until such recommendations may be withdrawn, in each case as permitted by this Agreement.

1.3 Company Actions. (a) On the date the Offer Documents are first filed with the SEC, the Company shall file with the SEC a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer containing the Special Committee Recommendation and the Company Board

Recommendation (together with all amendments, supplements and exhibits thereto, the “Schedule 14D-9”) and shall cause the Schedule 14D-9 to be disseminated to the holders of Public Shares with the Offer Documents, in each case in a manner that complies with Rule 14d-9 under the Exchange Act and the Securities Laws. The Company shall deliver copies of the proposed form of the Schedule 14D-9 to Parent within a reasonable time prior to the filing thereof with the SEC for review and comment by Parent and its counsel. Each of the Company, Parent and Merger Sub shall use reasonable best efforts promptly to correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect or as otherwise required by the Securities Laws. The Company shall take all steps necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule 14D-9, as so amended or supplemented, to be filed with the SEC and to be disseminated to the holders of Public Shares, in each case as and to the extent required by the Securities Laws. The Company shall provide Parent and its counsel with copies of any written comments, and shall inform them of any oral comments, that the Company or the Special Committee, or their respective counsel, receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after the receipt of such comments and shall give Parent and its counsel a reasonable opportunity under the circumstances to review and comment on any written or oral responses to such comments. The Company agrees to use reasonable best efforts to respond promptly to any comments of the SEC or its staff with respect to the Schedule 14D-9.

(b) In connection with the Offer, the Company shall promptly furnish or cause to be furnished to Parent (i) a list of the names and addresses of the record holders of Public Shares as of the most recent practicable date, as well as mailing labels containing such names and addresses and (ii) security position lists, computer files and any other information identifying the beneficial owners of Public Shares as of the most recent practicable date that the Company or the transfer agent have in their possession or control or can obtain without unreasonable effort or expense. The Company will furnish or cause to be furnished to Parent such additional information (including updates of the items provided pursuant to the preceding sentence) and such other assistance as Parent may reasonably request in communicating the Offer to the record and beneficial owners of Public Shares.

1.4 Schedule 13E-3. On the date of commencement of the Offer, the Company, Parent, Merger Sub and such other affiliates of Parent as may be required under applicable Law shall file with the SEC, pursuant to and in accordance with Rule 13e-3 and Regulation M-A, a joint Rule 13e-3 Transaction Statement on Schedule 13E-3 with respect to the Transactions (the “Schedule 13E-3”); provided that, at their option, subject to applicable Law, Parent and Merger Sub may include the Schedule 13E-3 in the Schedule TO included in the Offer Documents. Each of Parent, Merger Sub and the Company agrees to use reasonable best efforts promptly to respond to any comments of the SEC or its staff with respect to the Schedule 13E-3 and promptly to correct any information provided by it for use in the Schedule 13E-3 if and to the extent that such information shall become false or misleading in any material respect or

as otherwise required by the Securities Laws. Each party shall take all steps necessary to amend or supplement the Schedule 13E-3 and to cause the Schedule 13E-3, as so amended or supplemented, to be filed with the SEC, in each case as and to the extent required by the Securities Laws. Each of Parent, the Company and the Special Committee and its respective counsel shall be given reasonable opportunity under the circumstances to review and comment on the Schedule 13E-3 (including any amendments or supplements thereto) before it is filed with the SEC. Each of Parent, the Company and the Special Committee shall provide the others and their respective counsel with copies of any written comments, and shall inform them of any oral comments, such Person or its counsel receives from the SEC or its staff with respect to the Schedule 13E-3 promptly after the receipt of such comments and shall give the others a reasonable opportunity under the circumstances to review and comment on any written or oral responses to such comments. The Company hereby consents to the inclusion in the Schedule 13E-3 of the Special Committee Recommendation and the Company Board Recommendation as such recommendations may be amended and until such recommendations may be withdrawn, in each case as permitted by this Agreement.

1.5 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, Merger Sub shall be merged with and into the Company and the separate corporate existence of Merger Sub shall thereupon cease. The Company shall be the surviving corporation in the Merger (sometimes hereinafter referred to as the “Surviving Corporation”), and the separate corporate existence of the Company, with all its rights, privileges, immunities, powers and franchises, shall continue unaffected by the Merger, except as set forth in Article II. The Merger shall have the effects specified in the DGCL.

1.6 Effective Time. The Merger shall become effective at such time that a Certificate of Merger with respect to the Merger (the “Delaware Certificate of Merger”) has been executed, acknowledged and filed with the Secretary of State of the State of Delaware, as provided in Section 251 of the DGCL, or at such later time as may be agreed by the parties in writing and specified in the Delaware Certificate of Merger (the “Effective Time”). Subject to the terms and conditions of this Agreement, the Company and Parent will cause the Merger to be effective on the third business day (the “Closing Date”) following the day on which the last to be satisfied or waived of the conditions set forth in Article VII shall be satisfied or waived in accordance with this Agreement (other than those conditions that by their nature are to be satisfied on the Closing Date, but subject to the fulfillment or waiver of those conditions).

1.7 Closing. Unless otherwise mutually agreed in writing between the Company and Parent, the closing for the Merger (the “Closing”) shall take place at the offices of Xxxxxxxx & Xxxxxxxx LLP, 000 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, at 9:00 A.M. on the Closing Date.

1.8 Company Directors Prior to the Effective Time. If the 90% Requirement is not satisfied immediately after such time that Parent accepts for payment the Public

Shares tendered pursuant to the Offer (the “Acceptance Time”), then, from and after the Acceptance Time until the earlier of (a) the Effective Time and (b) such time that the 90% Requirement is satisfied, Parent shall use reasonable best efforts to cause the directors of the Company who are “independent” within the meaning of the corporate governance rules of the New York Stock Exchange (the “NYSE”) (the “Existing Independent Directors”) to remain as directors on the Company Board. If any Existing Independent Director is unable to serve due to death, disability or resignation, Parent shall use reasonable best efforts to ensure that such other Person (or Persons) as may be designated by the remaining Existing Independent Directors shall be elected or designated to fill such vacancy in accordance with the Company’s by-laws and each such Person shall be deemed to be an Existing Independent Director for purposes of this Agreement. Notwithstanding anything in this Agreement to the contrary, at any time prior to the Effective Time, Parent shall use its reasonable best efforts to cause its designees on the Company Board not to approve any amendment or termination by the Company of, or any waiver by the Company of any of its rights under, this Agreement that would adversely affect the holders of Public Shares or extend the time for performance of Parent’s or Merger Sub’s obligations under this Agreement, unless such action is approved by the Existing Independent Directors. Parent agrees that, from and after the date of this Agreement, subject to applicable Law, at all times prior to the earlier of (i) the Effective Time and (ii) the termination of this Agreement, it shall not authorize its designees on the Company Board to terminate the existence of the Special Committee or materially change its duties or authority or its current membership (so long as its existing members are willing to serve and have not been removed for cause).

ARTICLE IV

EFFECT OF THE MERGER ON CAPITAL STOCK;
EXCHANGE OF CERTIFICATES

4.1 Effect on Capital Stock. At the Effective Time, as a result of the Merger and without any action on the part of the holder of any capital stock of the Company:

(a) Merger Consideration. Each Public Share issued and outstanding immediately prior to the Effective Time other than (i) Public Shares owned by the Company or any direct or indirect wholly owned Subsidiary of the Company, and in each case not held on behalf of third parties, and (ii) Public Shares that are owned by stockholders (“Dissenting Stockholders”) who have properly perfected and not withdrawn a demand for appraisal rights pursuant to Section 262 of the DGCL (each, an “Excluded Share” and collectively, “Excluded Shares”) shall be converted into the right to receive an amount in cash equal to the Offer Price (the “Per Share Merger Consideration”). At the Effective Time, all such Public Shares shall cease to be outstanding, shall be cancelled and shall cease to exist, and each certificate (a “Certificate”) formerly representing such Public Shares shall thereafter represent only the right to receive the Per Share Merger Consideration, without interest.

(b) Cancellation of Excluded Shares; Parent-Owned Common Stock to Remain Outstanding. Each Excluded Share shall, by virtue of the Merger and without any action on the part of the holder thereof, cease to be outstanding, shall be cancelled without payment of any consideration therefor and shall cease to exist, subject to any rights the holder thereof may have under Section 4.2(f). Each share of Common Stock owned by MUFG or any of its Subsidiaries, other than shares of Common Stock held by MUFG or any of its Subsidiaries in a fiduciary or bailee capacity (which shall be deemed to be Public Shares in accordance with the definition thereof), shall remain outstanding as shares of the Surviving Corporation without change resulting from the Merger.

(c) Merger Sub. At the Effective Time, each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be cancelled without payment of any consideration therefor and shall cease to exist.

4.2 Exchange of Certificates.

(a) Paying Agent. From and after the Effective Time, Parent shall make available or cause to be made available to a paying agent selected by Parent with the Company’s prior approval, which shall not be unreasonably withheld (the “Paying Agent”), amounts sufficient in the aggregate to provide all funds necessary for the Paying Agent to make payments of the Per Share Merger Consideration pursuant to Section 4.1(a) (such cash hereinafter referred to as the “Exchange Fund”).

(b) Exchange Procedures. Promptly after the Effective Time (and in any event within three business days), the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of Public Shares (other than holders of Excluded Shares) (i) a letter of transmittal in customary form specifying that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or affidavits of loss in lieu thereof as provided in Section 4.2(e)) to the Paying Agent, such letter of transmittal to be in such form and have such other provisions as Parent and the Company may reasonably agree, and (ii) instructions for use in effecting the surrender of the Certificates (or affidavits of loss in lieu thereof as provided in Section 4.2(e)) in exchange for the Per Share Merger Consideration. Upon surrender of a Certificate (or affidavit of loss in lieu thereof as provided in Section 4.2(e)) to the Paying Agent in accordance with the terms of such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor a cash amount in immediately available funds (after giving effect to any required tax withholdings as provided in Section 4.2(g)) equal to (x) the number of Public Shares represented by such Certificate (or affidavit of loss in lieu thereof as provided in Section 4.2(e)) multiplied by (y) the Per Share Merger Consideration, and the Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates. In the event of a transfer of ownership of Public Shares that is not registered in the transfer records of the Company, a check for any cash to be exchanged upon due surrender of the Certificate may be issued to such transferee if the Certificate formerly representing such Public Shares is presented to the Paying Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid or are not applicable.

(c) Transfers. From and after the Effective Time, there shall be no transfers on the stock transfer books of the Company of the Public Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate is presented to the Surviving Corporation, Parent or the Paying Agent for

transfer, it shall be cancelled and exchanged for the cash amount in immediately available funds to which the holder thereof is entitled pursuant to this Article IV.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains unclaimed by the stockholders of the Company for 180 days after the Effective Time shall be delivered to the Surviving Corporation. Any holder of Public Shares (other than Excluded Shares) who has not theretofore complied with this Article IV shall thereafter look only to the Surviving Corporation for payment of the Per Share Merger Consideration (after giving effect to any required tax withholdings as provided in Section 4.2(g)) upon due surrender of its Certificates (or affidavits of loss in lieu thereof as provided in Section 4.2(e)), without any interest thereon. Notwithstanding the foregoing, none of the Surviving Corporation, Parent, the Paying Agent or any other Person shall be liable to any former holder of Public Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. For the purposes of this Agreement, the term “Person” shall mean any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity or other entity of any kind or nature.

(e) Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in customary amount and upon such terms as may be required by Parent as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent will issue a check in the amount (after giving effect to any required tax withholdings) equal to the number of Public Shares represented by such lost, stolen or destroyed Certificate multiplied by the Per Share Merger Consideration.

(f) Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, Public Shares held by Dissenting Stockholders shall not be converted into the right to receive the Per Share Merger Consideration with respect to the Public Shares owned by such Dissenting Stockholders, but instead shall be automatically cancelled and cease to exist, and each such Dissenting Stockholder shall be entitled to receive only the payment provided by Section 262 of the DGCL for such shares. Notwithstanding the foregoing, if any Person shall have effectively waived, withdrawn or lost such Person’s right to appraisal under Section 262 of the DGCL, then the Public Shares held by such Person shall be deemed to have been converted at the Effective Time into the Per Share Merger Consideration set forth in Section 4.1(a), without interest. The Company shall give Parent (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable law that are received by the Company relating to stockholders’ rights of appraisal and (ii) the opportunity to direct all negotiations and proceedings with respect to demand for appraisal under the DGCL. The Company shall not, except with the prior written consent

of Parent, voluntarily make any payment with respect to any demands for appraisal, offer to settle or settle any such demands or approve any withdrawal of any such demands.

(g) Withholding Rights. Each of Parent and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Public Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986 (the “Code”), as amended, or any other applicable state, local or foreign Tax Law. To the extent that amounts are so withheld by the Surviving Corporation or Parent, as the case may be, such withheld amounts (i) shall be remitted by Parent or the Surviving Corporation, as applicable, to the applicable Governmental Entity, and (ii) shall be treated for all purposes of this Agreement as having been paid to the holder of Public Shares in respect of which such deduction and withholding was made by the Surviving Corporation or Parent, as the case may be.

As used in this Agreement, (i) the term “Tax” (including, with correlative meaning, the term “Taxes”) includes all federal, state, local and foreign income, profits, franchise, gross receipts, environmental, customs duty, capital stock, severances, stamp, payroll, sales, employment, unemployment, disability, use, property, withholding, excise, production, value added, occupancy and other taxes, duties or assessments of any nature whatsoever, together with all interest, penalties and additions imposed with respect to such amounts and any interest in respect of such penalties and additions, and (ii) the term “Tax Return” includes all returns and reports (including elections, declarations, disclosures, schedules, estimates and information returns) required to be supplied to a Tax authority relating to Taxes.

4.3 Treatment of Stock Plans.

(a) Treatment of Options. At the Effective Time each outstanding option to purchase Common Stock (a “Company Option”) under the Stock Plans, vested or unvested, shall be cancelled and shall only entitle the holder thereof to receive, as soon as reasonably practicable after the Effective Time, an amount in cash equal to the product of (x) the total number of shares of Common Stock subject to the Company Option times (y) the excess, if any, of the Per Share Merger Consideration over the exercise price per share of Common Stock under such Company Option less applicable Taxes required to be deducted and withheld with respect to such payment.

(b) Company Awards.

6.5 Information Statement. At Parent’s option, this Agreement and the Merger may be approved by an irrevocable written consent (the “Written Consent”) executed by the holders of the requisite number of shares of Common Stock. In the event that Parent elects to obtain the Written Consent in lieu of obtaining stockholder approval at a Stockholders Meeting, Parent shall so notify the Company in writing and the Company shall prepare, file with the SEC and transmit to the holders of Public Shares a preliminary information statement of the Company relating to the Merger in accordance with the Company’s certificate of incorporation and by-laws, and in accordance with applicable Law, including Regulation 14C promulgated under the Exchange Act (the “Information Statement”).

(b) Cooperation. Subject to the terms and conditions set forth in this Agreement (including Section 6.13 of this Agreement), the Company and Parent shall cooperate with each other and use (and shall cause their respective Subsidiaries to use) their respective reasonable best efforts to take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under this Agreement and applicable Laws to consummate the Offer, the Merger and the other Transactions as soon as practicable, including preparing and filing as promptly as practicable all documentation to effect all necessary notices, reports and other filings and to obtain as promptly as practicable all consents, registrations, approvals, permits and

In exercising the foregoing rights, each of the Company and Parent shall act reasonably and as promptly as practicable. Subject to applicable Law, in the event that any administrative or judicial action or proceeding is instituted (or threatened to be instituted) by a private party against the Company or any of its Subsidiaries or their respective directors challenging the Transactions, the Company shall cooperate in all respects with Parent and use its reasonable best efforts to contest and resist any such action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the Transactions; provided that, in no event shall the Company be required to take any such actions that would reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

(c) Information. The Company and Parent each shall, upon request by the other, furnish the other with all information concerning itself, its Subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with the Offer Documents, the Schedule 13E-3 and the Information Statement or the Proxy Statement, as the case may be, or any other statement, filing, notice or application made by or on behalf of Parent, the Company or any of their respective Subsidiaries to any third party and/or any Governmental Entity in connection with the Offer, the Merger and the other Transactions; it being understood that in no event shall Parent be required to provide confidential information concerning Parent or any of its affiliates to the Company or any of its affiliates pursuant to this Section 6.6 or any subsection hereof.

(d) Status. Subject to applicable Laws and as required by any Governmental Entity, the Company and Parent each shall keep the other apprised of the status of matters relating to completion of the Offer, the Merger and the other

Transactions, including promptly furnishing the other with copies of notices or other communications received by Parent or the Company, as the case may be, or any of its Subsidiaries, from any third party and/or any Governmental Entity with respect to the Offer, the Merger and the other Transactions. The Company shall give prompt notice to Parent of any change, fact or condition that is reasonably expected to result in a Material Adverse Effect or of any failure of any condition in Exhibit 1 or Article VII. The Company shall not permit any of its officers or any other representatives or agents to participate in any meeting with any Governmental Entity in respect of any filings, investigation or other inquiry relating to the Offer, the Merger and the other Transactions unless it consults with Parent in advance and, to the extent permitted by such Governmental Entity, gives Parent the opportunity to attend and participate thereat.

(e) Rule 14d-10(c) Matters. Prior to the Expiration Date, the Compensation Committee will, to the extent it has not previously taken such action, (i) approve and/or ratify all Compensation Agreements and Benefit Plans as an “employment compensation, severance or other employee benefit arrangement” within the meaning of Rule 14d-10(d)(2) under the Exchange Act, and (ii) take all other actions necessary or advisable to satisfy the requirements of the non-exclusive safe harbor with respect to such Compensation Agreements and Benefit Plans in accordance with Rule 14d-10(d)(2) under the Exchange Act.

6.7 Access and Reports. Subject to applicable Law, upon reasonable notice, the Company shall (and shall cause its Subsidiaries to) afford Parent’s officers and other authorized representatives reasonable access, during normal business hours throughout the period prior to the Effective Time, to its employees, properties, books, contracts and records and, during such period, the Company shall (and shall cause its Subsidiaries to) furnish promptly to Parent all information concerning its business, properties and personnel as may reasonably be requested, provided that no investigation pursuant to this Section 6.7 shall affect or be deemed to modify any representation or warranty made by the Company herein, and provided, further, that the foregoing shall not require the Company (i) to permit any inspection, or to disclose any information, that in the reasonable judgment of the Company would result in the disclosure of any trade secrets of third parties or violate any of its obligations with respect to confidentiality if the Company shall have used reasonable best efforts to obtain the consent of such third party to such inspection or disclosure or (ii) to disclose any privileged information of the Company or any of its Subsidiaries. All requests for information made pursuant to this Section 6.7 shall be directed to the executive officer or other Person designated by the Company. All such information shall be governed by the terms of the Confidentiality Agreement.

6.8 Stock Exchange Delisting. Prior to the Closing Date, the Company shall cooperate with Parent and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of the NYSE to enable the delisting by the Surviving Corporation of the Common Stock from the NYSE and the

deregistration of the Common Stock under the Exchange Act as promptly as practicable after the earlier of (i) the Effective Time and (ii) such time as the Company qualifies for an issuer-initiated delisting under applicable Law and the rules and policies of the NYSE, and in any event no more than ten (10) days after the Closing Date.

6.9 Publicity. The initial press release regarding the Transactions shall be a joint press release and thereafter the Company and Parent each shall consult with each other prior to issuing any press releases or otherwise making public announcements with respect to the Transactions and prior to making any filings with any third party and/or any Governmental Entity (including any national securities exchange or interdealer quotation service) with respect thereto, except as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange or interdealer quotation service or by the request of any Governmental Entity; provided that in no event shall Parent be required to consult with the Company in connection with any filing with any Japanese Governmental Entity or the Tokyo Stock Exchange or in connection with providing any confidential information concerning Parent or any of its affiliates to any third party or Governmental Entity.

6.10 Expenses. Whether or not the Public Shares are purchased pursuant to the Offer, all costs and expenses incurred in connection with the Transactions shall be paid by the party incurring such expense, except that expenses incurred in connection with the filing fee for the Schedule TO and the publishing, printing and/or mailing of the Offer Documents shall be borne by Purchaser, and expenses incurred in connection with the Schedule 13E-3 and the Information Statement or the Proxy Statement, as the case may be (but not the attorney’s fees related thereto, which shall be paid by the party incurring such expense), shall be shared equally by Parent and the Company.

6.11 Indemnification; Directors’ and Officers’ Insurance. (a) From and after the Acceptance Time, and for a period of six years after the later of the Acceptance Time and the Effective Time, each of Parent and the Surviving Corporation agrees that, to the fullest extent permitted by Law, it will indemnify and hold harmless each present and former director and officer of the Company or any of its Subsidiaries (in each case, when acting in such capacity), determined as of the Acceptance Time (the “Indemnified Parties”), against any costs or expenses (including reasonable attorneys’ fees), judgments, settlements, fines, losses, claims, damages or liabilities (collectively, “Costs”) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, (and Parent or the Surviving Corporation shall also advance expenses as incurred to the fullest extent permitted under applicable Law, provided that the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification).

(b) Any Indemnified Party wishing to claim indemnification under Section 6.11(a), upon learning of any such claim, action, suit, proceeding or investigation,

shall promptly notify Parent and the Surviving Corporation thereof, but the failure to so notify shall not relieve Parent or the Surviving Corporation of any liability it may have to such Indemnified Party except to the extent such failure materially prejudices the indemnifying party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) Parent or the Surviving Corporation shall have the right to assume the defense thereof and Parent and the Surviving Corporation shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if Parent or the Surviving Corporation elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues that raise conflicts of interest between Parent or the Surviving Corporation, on the other hand, and the Indemnified Parties, on the other, the Indemnified Parties may retain counsel satisfactory to them, and Parent or the Surviving Corporation shall pay all reasonable fees and expenses of such counsel for the Indemnified Parties promptly as statements therefor are received; provided, however, that Parent and the Surviving Corporation shall be obligated pursuant to this paragraph (b) to pay for only one firm of counsel for all Indemnified Parties in any jurisdiction unless the use of one counsel for such Indemnified Parties would present such counsel with a conflict of interest; provided that the fewest number of counsels necessary to avoid conflicts of interest shall be used; (ii) the Indemnified Parties will cooperate in the defense of any such matter, and (iii) Parent and the Surviving Corporation shall not be liable for any settlement effected without their prior written consent; and provided, further, that Parent and the Surviving Corporation shall not have any obligation hereunder to any Indemnified Party if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law. If such indemnity is not available with respect to any Indemnified Party, then the Surviving Corporation and the Indemnified Party shall contribute to the amount payable in such proportion as is appropriate to reflect relative faults and benefits.

(c) Parent shall use its reasonable best efforts to cause the individuals serving as officers and directors of the Company or any of its Subsidiaries immediately prior to the Acceptance Time to be covered for a period of six (6) years from the Effective Time by the directors’ and officers’ liability insurance policy maintained by the Company (provided that Parent may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are not less advantageous than such policy) with respect to acts or omissions occurring prior to the Effective Time which were committed by such officers and directors in their capacity as such; provided, however, that in no event shall Parent be required to expend on an annual basis more than 300% of the current amount expended by the Company (the “Insurance Amount”) to maintain or procure insurance coverage, and further provided that if Parent is unable to maintain or obtain the insurance called for by this Section 6.11(c) Parent shall use all reasonable efforts to obtain as much comparable insurance as is available for the Insurance Amount.

(d) If Parent or the Surviving Corporation or any of their respective successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Surviving Corporation shall assume all of the obligations set forth in this Section 6.11.

(e) The provisions of this Section 6.11 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties.

(f) Parent and Merger Sub agree that all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, now existing in favor of the current or former directors or officers of the Company or its Subsidiaries as provided in their respective certificates of incorporation or by-laws or similar organizational documents shall survive the Merger and shall continue in full force and effect to the fullest extent permitted by Law. For a period of six (6) years from the Effective Time, to the fullest extent permitted by Law, Parent shall cause the Surviving Corporation to maintain in effect any and all exculpation, indemnification and advancement of expenses provisions of the Company’s and any of its Subsidiaries’ certificate of incorporation and by-laws or similar organizational documents in effect as of the date hereof or in any indemnification agreements of the Company or its Subsidiaries with any of their respective current or former directors or officers in effect as of the date hereof, and shall not amend, repeal or otherwise modify any such provisions in any manner that would adversely affect the rights thereunder of any individuals who at the Acceptance Time were current or former directors or officers of the Company or any of its Subsidiaries; provided, however, that all rights to indemnification in respect of any action, litigation, investigation, suit, arbitration or proceeding pending or asserted or any claim made within such period shall continue until the disposition of such action, litigation, investigation, suit, arbitration or proceeding or resolution of such claim.

6.12 Takeover Statutes. If any Takeover Statute is or may become applicable to the Offer, the Merger or the other Transactions, the Company and the Company Board shall grant such approvals and take such actions as are necessary so that such Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise act to eliminate or minimize the effects of such statute or regulation on such Transactions.

6.13 Tail Period. Notwithstanding anything to the contrary in this Agreement, the Company acknowledges and agrees that, during the six months from and after the Acceptance Time (the “Tail Period”) if and for so long as the 90% Requirement is not satisfied, Parent is not required to take any action to acquire Public Shares. Without limiting the foregoing, during the Tail Period, Parent and its affiliates may (but are not required to) purchase Public Shares on the open market and in privately negotiated

transactions in accordance with applicable Law; provided that neither Parent nor any of its affiliates may commence a “tender offer” (within the meaning of the Exchange Act and the rules and regulations promulgated thereunder) during the Tail Period without the Company’s consent. During the Tail Period, Parent shall notify the Company in writing promptly after the 90% Requirement is satisfied. For the avoidance of doubt, if and when the 90% Requirement is satisfied at any time during the Tail Period, (i) consistent with Section 6.6(b) of this Agreement but without limiting Section 8.1(f) of this Agreement, the Company and Parent shall use (and shall cause their respective Subsidiaries to use) their respective reasonable best efforts to take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under this Agreement and applicable Laws to consummate the Merger and the other Transactions as soon as practicable and (ii) consistent with Section 4.1(a) of this Agreement, the Per Share Merger Consideration payable in connection with the Merger shall be equal to the Offer Price.

6.14 Tax Certificate. The Company shall use its reasonable best efforts to provide to Parent immediately prior to the Closing a statement pursuant to Treasury Regulation Section 1.1445-2(c)(3) certifying that the Company is not a U.S. real property interest (as defined by the Code).

6.15 Formation of Merger Sub; Accession. As promptly as reasonably practicable after the date hereof, and in any event within ten business days after the date hereof, Parent shall form a Delaware corporation as a direct wholly owned Subsidiary of Parent (“Merger Sub”). As promptly as reasonably practicable after incorporating Merger Sub, (x) Parent, in its capacity as the sole shareholder of Merger Sub, shall approve and adopt this Agreement and (y) Parent shall cause Merger Sub to accede to this Agreement by executing a signature page to this Agreement, after which time Merger Sub shall be a party hereto for all purposes set forth herein. Notwithstanding any provision herein to the contrary, (i) the obligations of Merger Sub to perform its covenants hereunder shall commence only at the time of its incorporation and (ii) the representations and warranties of Merger Sub set forth in Section 5.3 shall be deemed to have been made as though Merger Sub had been a party to this Agreement as of the date hereof. Prior to the Effective Time, Parent shall take such actions as are reasonably necessary to cause the Board of Directors of Merger Sub to unanimously approve this Agreement and declare it advisable for Merger Sub to enter into this Agreement. Notwithstanding anything to the contrary in this Agreement, Parent and its Affiliates may amend, or cause to be amended, the by-laws of Merger Sub at any time prior to the Effective Time so long as such amendment would not impair, delay or prevent the Closing.

9.7 Entire Agreement. This Agreement (including any exhibits hereto), the Company Disclosure Letter and the Confidentiality Agreement, dated July 2, 2008, between Parent and the Company (the “Confidentiality Agreement”) constitute the entire agreement, and supersede all other prior agreements, understandings, representations and warranties both written and oral, among the parties, with respect to the subject matter hereof.

9.8 No Third Party Beneficiaries. Except as provided in Section 6.11 (Indemnification; Directors’ and Officers’ Insurance) only, Parent, Merger Sub and the Company hereby agree that their respective representations, warranties and covenants set forth herein are solely for the benefit of the other parties hereto, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does

not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including, without limitation, the right to rely upon the representations and warranties set forth herein. Except for Section 6.11(f) with respect to which rights of third party beneficiaries arise as of the date of this Agreement, the parties hereto further agree that the rights of third party beneficiaries under Section 6.11 shall not arise unless and until the Acceptance Time occurs. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties hereto. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with Section 9.3 without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

9.9 Obligations of Parent and of the Company. Whenever this Agreement requires a Subsidiary of Parent to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action. Whenever this Agreement requires a Subsidiary of the Company to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause such Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Corporation to cause such Subsidiary to take such action.

9.10 Definitions. Each of the terms set forth in Annex A is defined in the Section of this Agreement set forth opposite such term, and such definitions shall apply regardless of where the terms appear in this Agreement. As used in this Agreement, the terms “beneficial ownership” (and its correlative terms) and “affiliate” shall have the meanings assigned to such terms in Rule 13d-3 and Rule 12b-2 under the Exchange Act, respectively.

9.11 Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and, so long as the effect of substituting such provision in accordance with the foregoing is no more adverse to any party than this Agreement in the form executed as of the date hereof, (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

9.12 Interpretation; Construction. (a) The table of contents and headings herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to a Section or Exhibit, such reference shall be to a Section of or Exhibit to this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.”

(b) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

(c) Each party hereto has or may have set forth information in its respective Disclosure Letter in a section thereof that corresponds to the section of this Agreement to which it relates. The fact that any item of information is disclosed in a Disclosure Letter to this Agreement shall not be construed to mean that such information is required to be disclosed by this Agreement.

9.13 Assignment. This Agreement shall not be assignable other than by operation of law; provided, however, that Parent may designate, by written notice to the Company, another wholly owned direct or indirect Subsidiary to be a Constituent Corporation in lieu of Merger Sub, in which event all references herein to Merger Sub shall be deemed references to such other Subsidiary, except that all representations and warranties made herein with respect to Merger Sub as of the date of this Agreement shall be deemed representations and warranties made with respect to such other Subsidiary as of the date of such designation; provided that any such designation shall not materially impede or delay the consummation of the Transactions or otherwise materially impede the rights of the stockholders of the Company under this Agreement. Any purported assignment in violation of this Agreement shall be null and void.
