AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER, dated as of May 6, 2007 (this “Agreement”), is among Liberty Mutual Insurance Company, a Massachusetts stock insurance company (“Parent”), Waterfall Merger Corp., an Ohio corporation and a direct, wholly owned subsidiary of Parent (“Merger Sub”), and Ohio Casualty Corporation, an Ohio corporation (the “Company” and, collectively with Parent and Merger Sub, the “parties”).

RECITALS

WHEREAS, the respective Boards of Directors of the Company, Parent and Merger Sub have deemed it advisable and in the best interests of their respective corporations and shareholders that the Company and Parent engage in a business combination; and

WHEREAS, in furtherance thereof, the respective Boards of Directors of the Company, Parent and Merger Sub have approved this Agreement and the merger (the “Merger”) of Merger Sub with and into the Company, on the terms and subject to the conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements set forth in this Agreement, and intending to be legally bound hereby, the parties hereby agree as follows:

ARTICLE I

THE MERGER; CERTAIN RELATED MATTERS

Section 1.1. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with Section 1701.78 and 1701.81 of the Ohio Revised Code (the “OGCL”), 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 (with respect to all post-Closing periods, the “Surviving Corporation”). At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Certificate of Merger and the applicable provisions of the OGCL, including Section 1701.82.

Section 1.2. Closing. The closing of the Merger (the “Closing”) shall take place at the offices of Debevoise & ▇▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ at 9:00 a.m. New York City time on the third Business Day after all of the conditions set forth in Article VII have been fulfilled or waived (other than those conditions that by their nature are to be satisfied at the Closing, but subject to fulfillment or waiver of those conditions) in accordance with this Agreement, or at such other place

and time and/or on such other date as the Company and Parent may agree in writing (the “Closing Date”).

Section 1.3. Effective Time. Subject to the provisions of this Agreement, as soon as practicable on the Closing Date, the parties shall duly execute and file a certificate of merger, in such form as is required by, and executed in accordance with, the relevant provisions of the OGCL (the “Certificate of Merger”), together with any required related certificates, with the Secretary of State of the State of Ohio (the “OSOS”) in accordance with the OGCL. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the OSOS on the Closing Date, or at such later time as Parent and the Company shall agree and specify in the Certificate of Merger in accordance with the OGCL. As used herein, the “Effective Time” shall mean the time at which the Merger shall become effective.

Section 1.4. Articles of Incorporation. The articles of incorporation of the Surviving Corporation shall be amended and restated at the Effective Time to be in the form attached as Exhibit A hereto and, as so amended and restated, such articles of incorporation shall be the articles of incorporation of the Surviving Corporation (the “Articles of Incorporation”), until thereafter amended as provided therein or by applicable Law.

Section 1.5. Code of Regulations. The code of regulations of Merger Sub in effect immediately prior to the Effective Time shall be the code of regulations of the Surviving Corporation (the “Code of Regulations”) until thereafter amended as provided therein or by applicable Law.

Section 1.6. Directors. The directors of Merger Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Articles of Incorporation and the Code of Regulations.

Section 1.7. Officers. The officers of the Company immediately prior to the Effective Time shall, from and after the Effective Time, be the officers of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Articles of Incorporation and the Code of Regulations.

Section 1.8. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of any holder thereof (other than the requisite approval of the Merger by the shareholders of the Company in accordance with the OGCL):

(a) each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (collectively, the “Shares”) (other than Excluded Shares and Dissenting Shares) shall be converted into the right to receive $44 in cash, without interest (the “Merger Consideration”);

(b) all Shares (other than Excluded Shares and Dissenting Shares) shall cease to be outstanding and shall be canceled and retired, and each certificate that, immediately prior to the Effective Time, represented any such Shares (the “Certificates”) shall thereafter represent only the right to receive the Merger Consideration with respect to such Shares formerly represented thereby;

(c) each Excluded Share shall cease to be outstanding and shall be canceled and retired and no consideration shall be delivered in exchange therefor; and

(d) each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and non-assessable share of common stock, par value $0.01 per share, of the Surviving Corporation and such shares shall constitute the only issued and outstanding shares of common stock of the Surviving Corporation.

Section 1.9. Treatment of Company Equity Awards.

(a) Company Options. At the Effective Time, the right to receive shares of Company Common Stock pursuant to the exercise of any stock options (each, a “Company Option”) granted pursuant to the Company’s 2002 Stock Incentive Plan, 2005 Incentive Plan, 2000 Directors Plan, 1999 Broad-Based Employees Stock Option Plan, 1993 Stock Incentive Program and stock options granted pursuant to ▇▇▇ ▇▇▇▇▇▇▇▇▇▇’▇ employment agreement and any applicable agreements under the foregoing (together, the “Company Incentive Plans”) that are outstanding immediately prior to the Effective Time, whether or not vested, shall be converted into the right to receive, as soon as reasonably practicable after the Effective Time (but in any event no later than five Business Days after the Effective Time), a cash payment equal to the product of (i) the excess, if any, of (A) the Merger Consideration over (B) the per share exercise price of such Company Option, multiplied by (ii) the number of shares covered by such Company Option, less (iii) any required withholding taxes. Any stock appreciation rights granted in tandem with a Company Option shall be cancelled without payment.

(b) Stock Appreciation Rights. At the Effective Time, the right to receive shares of Company Common Stock or cash pursuant to the exercise of any freestanding stock appreciation rights (each, a “Company SAR”) granted pursuant to the Company Incentive Plans or any agreement thereunder that is outstanding immediately prior to the Effective Time, whether or not vested, shall be converted into the right to receive, as soon as reasonably practicable after the Effective Time (but in any event no later than five Business Days after the Effective Time), a cash payment equal to the product of (i) the

excess, if any, of (A) the Merger Consideration, over (B) the per share exercise price of such Company SAR, multiplied by (ii) the number of shares covered by such Company SAR, less (iii) any required withholding taxes.

(c) Company Restricted Shares. Immediately prior to the Effective Time, the Company shall waive any vesting conditions applicable to any shares of restricted stock (each, a “Company Restricted Share”) granted pursuant to the Company Incentive Plans, and such Company Restricted Shares shall be treated the same as other Shares for purposes of this Agreement.

(d) Director Units. At the Effective Time, the right to receive cash in respect of director performance shares granted pursuant to the Second Amended and Restated Directors’ Deferred Compensation Plan (each, a “Director Unit”) that (i) are outstanding, and (ii) have not been converted into cash as of the Effective Time shall be converted into the right to receive, as soon as reasonably practicable after the Effective Time (but in any event no later than five Business Days after the Effective Time), a cash payment equal to the Merger Consideration for each Share to which such Director Unit relates, less any required withholding taxes.

(e) Performance-Based Awards. At the Effective Time, the right to receive shares of Company Common Stock or cash in respect of outstanding Performance-Based Awards under the Company Incentive Plans (each, a “Performance-Based Award”), whether or not vested, shall be cancelled and shall only entitle the holder of such Performance-Based Award to receive, as soon as reasonably practicable after the Effective Time (but in any event no later than five Business Days after the Effective Time), a cash payment equal to (i) the number of shares issuable pursuant to the Performance-Based Award calculated at the higher of the “target level” and the award level actually met as of the Effective Time as determined by the compensation committee of the Board of Directors prior to the Effective Time in good faith in accordance with the terms of the Company Incentive Plans and the Performance-Based Award, multiplied by (ii) the per share Merger Consideration, multiplied by (iii) a fraction, the numerator of which is the number of whole calendar months between the beginning of the performance period (as defined under the respective Company Incentive Plan or award agreement under which the award was granted, as appropriate) and the Effective Time, and the denominator of which is the whole number of calendar months in such performance period, less applicable Taxes required to be withheld with respect to such payment. The Company shall provide Parent the compensation committee’s determination of the award level actually met at least three Business Days prior to the Closing.

(f) Automatic Cancellation. As of the Effective Time, all Company Options (including any stock appreciation rights granted in tandem with such Company Options), Company SARs, Company Restricted Shares, Director Units, Performance-Based Awards and other equity-based awards granted by the Company (together, “Company Equity Awards”) shall no longer be outstanding and shall automatically be canceled and

retired and shall expire and cease to exist, and each holder of such a Company Equity Award shall cease to have any rights with respect thereto, except the rights specified in this Section 1.9. The consideration pursuant to this Section 1.9 (the “Equity Award Consideration”) shall be paid to each holder of a Company Equity Award in accordance with Article II.

(g) Prior to the Effective Time, the Company shall adopt such resolutions and take or cause to be taken prior to the Effective Time all such other action as may reasonably be required to effectuate the actions contemplated by this Section 1.9.

Section 1.10. Certain Adjustments. If, between the date of this Agreement and the Effective Time, the Company Common Stock is changed into a different number of shares or different class by reason of any reclassification, recapitalization, stock split, split-up, combination or exchange of shares, or a stock dividend or dividend payable in any other securities is declared with a record date within such period, or any similar event occurs, the Merger Consideration shall be appropriately adjusted to provide to the holders of Shares or Company Equity Awards the same economic effect as contemplated by this Agreement prior to such event.

Section 1.11. Appraisal Rights. Notwithstanding any provision of this Agreement to the contrary (other than the other provisions of this Section 1.11) and to the extent available under the OGCL, no shares of Company Common Stock held by a Person who has perfected a demand for appraisal rights pursuant to Section 1701.85 of the OGCL (a “Dissenting Shareholder”) shall be converted into, or represent the right to receive, the Merger Consideration. Any such shareholder shall instead be entitled to receive payment of the fair cash value of such Dissenting Shareholder’s Dissenting Shares in accordance with the provisions of Section 1701.85 of the OGCL; provided, however, that all Dissenting Shares held by any Dissenting Shareholder who shall have failed to perfect or who otherwise shall have withdrawn, in accordance with Section 1701.85 of the OGCL, or lost such Dissenting Shareholder’s rights to appraisal of such shares under Section 1701.85 of the OGCL shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without any interest thereon, upon surrender of the Certificate or Certificates that formerly evidenced such shares in the manner provided in Article II. The Company shall give Parent (a) prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law received by the Company relating to shareholders’ rights of appraisal and (b) the opportunity to participate in all negotiations and proceedings with respect to demand for appraisal under the OGCL. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any demands for appraisals of Dissenting Shares or settle any such demands.

ARTICLE II

EXCHANGE OF CERTIFICATES AND COMPANY EQUITY AWARDS

Section 2.1. Exchange Fund. Prior to the Effective Time, Parent shall appoint a commercial bank or trust company with the Company’s prior approval (such approval not to be unreasonably withheld or delayed) to act as exchange agent hereunder for the purpose of exchanging Certificates for the Merger Consideration and the Company Equity Awards for the Equity Award Consideration (the “Exchange Agent”). At or prior to the Effective Time, Parent shall deposit with the Exchange Agent, in trust for the benefit of holders of Shares and the Company Equity Awards an amount of cash representing the aggregate cash consideration payable pursuant to Section 1.8 and Section 1.9. Any cash deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund”.

Section 2.2. Exchange Procedures. Promptly after the Effective Time (and in any event, within three Business Days), the Surviving Corporation shall cause the Exchange Agent to mail (x) to each holder of record of Shares (other than holders of Excluded Shares) immediately prior to the Effective Time (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates (or affidavits of loss in lieu of the Certificates as provided in Section 2.7) to the Exchange Agent, and which letter shall be in customary form and have such other provisions as Parent and the Company may reasonably agree and (ii) instructions for effecting the surrender of such Certificates (or affidavits of loss in lieu of such Certificates as provided in Section 2.7) in exchange for the Merger Consideration and (y) to each holder of a Company Equity Award, a check in an amount due and payable to such holder pursuant to Section 1.9 hereof in respect of such Equity Award. Upon surrender of a Certificate (or affidavits of loss in lieu of a Certificate as provided in Section 2.7) to the Exchange Agent together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate (or provider of an affidavit as provided in Section 2.7) shall be entitled to receive in exchange therefor a check in an amount equal to the Merger Consideration multiplied by the number of Shares represented by such holder’s properly surrendered Certificates (or affidavits of loss in lieu of such Certificates as provided in Section 2.7). No interest will be paid or will accrue on any cash payable pursuant to Section 1.8. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, a check in the proper amount of any cash consideration pursuant to Section 1.8 may be issued with respect to such Shares to such a transferee if the Certificate representing such Shares is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid.

Section 2.3. No Further Ownership Rights in Company Common Stock. All cash paid upon conversion of the Shares in accordance with the terms of Article I and this Article II shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to the Shares previously represented by such Certificates (or affidavits of loss in lieu of a Certificate as provided in Section 2.7).

Section 2.4. Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Certificates for six months after the Effective Time shall be delivered to the Surviving Corporation (or otherwise on the instruction of Parent), and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation for the Merger Consideration with respect to the Shares formerly represented thereby to which such holders are entitled pursuant to Section 1.8. Any such portion of the Exchange Fund remaining unclaimed by holders of Shares five years after the Effective Time (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity) shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation free and clear of any claims or interest of any Person previously entitled thereto.

Section 2.5. No Liability. None of Parent, Merger Sub, the Company, the Surviving Corporation, any of their respective Affiliates or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration from the Exchange Fund delivered to a public official or Governmental Entity pursuant to any applicable abandoned property, escheat or similar Law.

Section 2.6. Investment of the Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent; provided that such investments shall be in obligations of or guaranteed by the United States of America or in commercial paper obligations rated A-1 or P-1 or better by ▇▇▇▇▇’▇ Investors Service, Inc. or Standard & Poor’s Corporation, respectively or a combination of the foregoing or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1,000,000,000 and, in any such case, no such instrument shall have a maturity exceeding three months. To the extent that there are losses with respect to such investments, or the Exchange Fund diminishes for other reasons below the level required to make prompt cash payment of the aggregate consideration payable pursuant to Section 1.8 and Section 1.9, Parent shall promptly replace or restore the cash in the Exchange Fund lost through such investments or other events so as to ensure that the Exchange Fund is at all times maintained at a level sufficient to make such cash payments. Any interest and other income resulting from any such investments shall become a part of the Exchange Fund, and any amounts in excess of the aggregate cash consideration payable pursuant to Section 1.8 and Section 1.9 shall be promptly returned to Parent upon request.

Section 2.7. Lost Certificates. If 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 the Surviving Corporation, the posting by such Person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect to the Shares formerly represented thereby.

Section 2.8. Withholding Rights. Each of Parent and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares (including, for the avoidance of doubt, Company Restricted Shares) or Company Equity Awards or any other equity rights in the Company such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or non-U.S. Law. To the extent that amounts are so withheld and paid to the appropriate taxing authority by Parent or the Exchange Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by the Surviving Corporation or Parent, as the case may be.

Section 2.9. Share Transfer Books. The share transfer books of the Company shall be closed at the Effective Time and there shall be no further registration of transfers of shares of Company Common Stock on the records of the Company. From and after the Effective Time, any Certificates (or effective affidavits of loss in lieu thereof) presented to the Exchange Agent or Parent for any reason shall be converted into the right to receive the Merger Consideration with respect to the shares of Company Common Stock formerly represented thereby.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as set forth in the Company SEC Documents filed on or after January 1, 2006 and prior to the date of this Agreement (excluding any disclosure set forth in the sections titled “risk factors” and “forward-looking statements”) or otherwise disclosed to Parent in the corresponding sections or subsections of the schedule (the “Company Disclosure Schedule”) delivered to it by the Company prior to the execution of this Agreement (it being agreed that disclosure of any item in any section or subsection of the Company Disclosure Schedule shall be deemed disclosure with respect to any other section or subsection to which the relevance of such disclosure to the applicable representation and warranty is reasonably apparent), the Company represents and warrants to Parent and Merger Sub as follows:

Section 3.1. Corporate Existence and Power. The Company is a corporation duly incorporated and validly existing under the laws of the State of Ohio and the Company and the Company Subsidiaries have all corporate, partnership or other similar powers and all governmental licenses, authorizations, permits, consents, franchises, variances, exemptions, orders and approvals required to carry on their business as now conducted (the “Company Permits”), except for those powers, licenses, authorizations, permits, consents, franchises, variances, exemptions, orders and approvals the absence of which are not, individually or in the aggregate, reasonably likely to have a Material Adverse Effect on the Company. The Company and the Company Subsidiaries are in compliance with the terms of the Company Permits, except where the failure to be in such compliance, individually or in the aggregate, is not reasonably likely to have a Material Adverse Effect on the Company. The Company is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where such qualification is required, except for those jurisdictions where failure to be so qualified is not, individually or in the aggregate, reasonably likely to have a Material Adverse Effect on the Company. The Company has made available to Parent true and complete copies of the articles of incorporation and code of regulations or similar organizational documents of the Company and each Significant Subsidiary as currently in effect.

Section 3.2. Corporate Authorization.

(a) The execution, delivery and performance by the Company of this Agreement and the consummation by the Company of the transactions contemplated hereby are within the Company’s corporate powers and, except for the Company Shareholder Approval, have been duly authorized by all necessary corporate action on the part of the Company. This Agreement has been duly executed and delivered by the Company and constitutes a valid and binding agreement of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights or by general equity principles, regardless of whether such enforceability is considered in a proceeding in equity or at law (the “Bankruptcy and Equity Exception”). The only vote of the holders of any class or series of capital stock of the Company necessary to consummate the Merger and the other transactions contemplated by this Agreement is the affirmative vote of the holders of the Company Common Stock representing a majority of the votes eligible to be cast by such holders approving the Merger and the Agreement at a shareholder’s meeting duly called and held for such purpose (the “Company Shareholder Approval”).

(b) At a meeting duly called and held, the Board of Directors of the Company has (i) determined that the Merger and the other transactions contemplated hereby are fair to and in the best interests of the Company’s shareholders, (ii) approved this Agreement and the transactions contemplated hereby in accordance with the OGCL, and

(iii) resolved (subject to Section 6.3) to recommend adoption of this Agreement by its shareholders.

Section 3.3. Governmental Authorization. The execution, delivery and performance by the Company of this Agreement, and the consummation by the Company of the transactions contemplated hereby require no consent or approval by, or filing with, any Governmental Entity, to be obtained or made by the Company other than (i) the filing of the Certificate of Merger with the OSOS and appropriate documents with the relevant authorities of other states in which the Company is qualified to do business, (ii) compliance with any applicable requirements of the HSR Act, (iii) compliance with any applicable requirements of the Securities Act, the Exchange Act, and any other applicable securities laws, (iv) compliance with any applicable requirements of the Nasdaq, (v) approvals or filings under all applicable state Laws regulating the business of insurance (collectively, “Insurance Laws”) as set forth in Section 3.3 of the Company Disclosure Schedule (the “Company Insurance Approvals”) and (vi) any consents, approvals or filings the absence of which are not, individually or in the aggregate, reasonably likely to have a Material Adverse Effect on the Company or prevent, materially delay or materially impair the consummation of the transactions contemplated by this Agreement.

Section 3.4. Non-Contravention. The execution, delivery and performance by the Company of this Agreement do not, and the consummation of the transactions contemplated hereby will not, constitute or result in (i) a violation or breach of any provision of the articles of incorporation or code of regulations of the Company or any organizational documents of any Company Subsidiary, (ii) assuming compliance with the matters referred to in Section 3.3, a violation or breach of any provision of any applicable Law, Order or Company Permit, (iii) a default under, or an event that, with or without notice or lapse of time or both, would constitute a default under, or cause or permit the termination, cancellation or acceleration of any right or obligation of the Company or any Company Subsidiary, or require any consent by or notice to any Person, under (A) any agreement or other instrument binding upon the Company or any Company Subsidiary that involves payments of $5,000,000 or more or (B) any material contract for the Company’s “Policy Administration Rating and Issuance System” (P.A.R.I.S.) or (iv) the creation or imposition of any Lien on any asset of the Company or any Company Subsidiary, except for such violations or breaches referred to in clause (ii) and for such Liens referred to in clause (iv) that are not, individually or in the aggregate, reasonably likely to have a Material Adverse Effect on the Company or prevent, materially delay or materially impair the consummation of the transactions contemplated by this Agreement.

Section 3.5. Capitalization.

(a) The authorized capital stock of the Company consists of (i) 150,000,000 common shares, $.125 par value (“Company Common Stock”), and (ii) 2,000,000 preferred shares, $.01 par value (“Company Preferred Stock”). As of May 3, 2007, (i)

59,984,141 shares of Company Common Stock (including 101,500 Company Restricted Shares) were issued and outstanding; and (ii) no shares of Company Preferred Stock were issued and outstanding. As of May 3, 2007, (i) Company Options to purchase an aggregate of 3,445,080 shares of Company Common Stock (of which options to purchase an aggregate of 2,942,593 shares of Company Common Stock were exercisable) were issued and outstanding, (ii) Company SARs covering an aggregate of 350,000 shares of Company Common Stock (of which Company SARs covering 116,666 shares of Company Common Stock were exercisable), (iii) Performance-Based Awards covering an aggregate of up to 825,925 shares of Company Common Stock, and (iv) Director Units covering an aggregate of 46,435 shares of Company Common Stock.

The Company has made available to Parent a list of all pending market conduct examinations as of the date hereof by an insurance regulatory Governmental Entity relating to any Company Subsidiary that is a Significant Subsidiary.

Where the Company Subsidiary is a cedent, the Company has not received any written notice to the effect that the financial condition of any party to any such agreement is impaired such that a default thereunder may reasonably be anticipated, whether or not such default may be cured by the operation of any offset clause in such agreement.

To the knowledge of the Company, each Company

Actuarial Analysis was based upon, in all material respects, an accurate inventory of policies in force for the Company and the Company Subsidiaries, as the case may be, at the relevant time of preparation and was prepared in conformity with generally accepted actuarial principles in effect at such time, consistently applied (except as may be noted therein).

Except as set forth in Section 3.21(e) of the Company Disclosure Schedule, no person is entitled to receive any additional payment (including any tax gross up or other payment) from the Company or any Company Subsidiary or any other person as a result of the imposition of the excise tax required by Section 4999(a) of the Code.

Section 6.3. No Solicitation.

(a) The Company shall immediately cease, and shall cause each Company Subsidiary and each of their respective Representatives to, immediately cease any discussions or negotiations with any parties conducted prior to the date hereof with respect to a Takeover Proposal. Except as permitted by this Section 6.3, after the execution and delivery of this Agreement, the Company and its directors and officers shall not, and shall cause each Company Subsidiary and use its reasonable best efforts to cause its and each Company Subsidiary’s Representatives not to, directly or indirectly, (i) solicit, initiate or knowingly encourage any inquiry with respect to, or the making of, any proposal that constitutes or could reasonably be expected to lead to a Takeover Proposal, (ii) participate in any negotiations regarding a Takeover Proposal with, or furnish any nonpublic information relating to a Takeover Proposal to, any Person that has made or, to the knowledge of the Company, is considering making a Takeover Proposal, or (iii) engage in discussions regarding a Takeover Proposal with any Person that has made, or, to the knowledge of the Company, is considering making, a Takeover Proposal, except to notify such Person of the existence of the provisions of this Section 6.3.

(b) Notwithstanding Section 6.3(a), prior to the time, but not after, the Company Shareholder Approval is obtained, if the Company receives a written and unsolicited Takeover Proposal that the Board of Directors of the Company reasonably believes to be credible, which the Board of Directors of the Company determines in good faith (after consultation with its financial advisors and outside counsel) is or could reasonably be expected to result in a Superior Proposal, the Company may take the following actions: (1) furnish nonpublic information to the Person making such

Takeover Proposal, but only if (A) prior to so furnishing such information, the Company has entered into a Qualifying Confidentiality Agreement with such Person, and (B) all such information has previously been provided to Parent and Merger Sub or is provided to Parent and Merger Sub prior to or contemporaneously with the time it is provided to the Person making such Takeover Proposal or such Person’s Representatives, and (2) engage or participate in any discussions or negotiations with such Person with respect to the Takeover Proposal. The Company promptly (and in any event within 48 hours) shall advise Parent orally and in writing of the receipt of (i) any proposal that constitutes or could reasonably be expected to lead to a Takeover Proposal and the material terms of such proposal (including the identity of the party making such proposal and, if applicable, copies of any documents or correspondence evidencing such proposal), and (ii) any request for non-public information relating to the Company or any Company Subsidiary other than requests for information not reasonably expected to be related to a Takeover Proposal. The Company shall, thereafter, keep Parent reasonably informed on a reasonably current basis of the status of any such Takeover Proposal (including any material change to the terms thereof).

(c) The Board of Directors of the Company shall not (i) withhold, withdraw or modify (or publicly propose to withhold, withdraw or modify), in a manner adverse to Parent, the Company Recommendation, (ii) approve or recommend (or publicly propose to approve or recommend ) any Takeover Proposal or (iii) take any action to render the Rights Agreement inapplicable to a Third Party, (it being understood that the Board of Directors may take no position with respect to a Takeover Proposal that takes the form of a tender offer until the close of business as of the tenth Business Day after the commencement of such tender offer pursuant to Rule 14d-2 under the Exchange Act without such action being considered an adverse modification) (any of the foregoing, a “Change in the Company Recommendation”). The Company shall not, and the Board of Directors shall not allow the Company to, and the Company shall not allow any Company Subsidiary to, in each case except as permitted by Section 8.1 hereof, enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (except for Qualifying Confidentiality Agreements permitted under Section 6.3(b)) relating to any Takeover Proposal.

(d) Notwithstanding anything to the contrary set forth in this Agreement, the Board of Directors of the Company may, prior to but not after the time the Company Shareholder Approval is obtained, (1) make a Change in Company Recommendation and/or (2) terminate this Agreement pursuant to Section 8.1, in each case of clauses (1) or (2), if the Board of Directors of the Company has determined in good faith, after consulting with its outside counsel, that the failure to take such action would be inconsistent with the directors’ fiduciary duties under applicable Law; provided that the Board of Directors may not take any such action in connection with a Takeover Proposal unless (1) such Takeover Proposal constitutes a Superior Proposal, (2) prior to terminating this Agreement pursuant to Section 8.1(d)(ii), the Company provides prior

written notice to Parent at least three Business Days in advance (the “Notice Period”) of its intention to take such action, which notice shall specify all material terms and conditions of such Superior Proposal (including the identity of the party making such Superior Proposal and copies of any documents or correspondence evidencing such Superior Proposal), and any material modifications to any of the foregoing, (3) during the Notice Period the Company shall, and shall cause its financial advisors and outside counsel to, negotiate with Parent in good faith should Parent propose to make such adjustments in the terms and conditions of this Agreement so that such Takeover Proposal ceases to constitute (in the good faith judgment of the Board of Directors) a Superior Proposal and (4) such Takeover Proposal continues to constitute (in the good faith judgment of the Board of Directors) a Superior Proposal after taking into account any such amendments that Parent shall have agreed to make prior to the end of the Notice Period.

(e) Nothing contained in this Section 6.3 shall prohibit the Company from (i) complying with its disclosure obligations under U.S. federal or state law with regard to a Takeover Proposal, including Rule 14a-9, 14d-9 or 14e-2 promulgated under the Exchange Act, (ii) making any disclosure to the Company’s shareholders if, after consultation with its outside legal counsel, the Company determines that such disclosure would be required under applicable Law or (iii) informing any Person of the existence of the provisions contained in this Section 6.3.

(f) For purposes of this Agreement:

“Takeover Proposal” means any proposal or offer (i) with respect to a merger, consolidation, business combination, share exchange or similar transaction involving the Company or any Company Subsidiary (any of the foregoing, a “Business Combination Transaction”) with any Person other than Parent, Merger Sub or any controlled Affiliate thereof (a “Third Party”), or (ii) to acquire directly or indirectly, whether by tender or exchange offer or otherwise, by any Third Party, 20% or more of the total voting power of any class, share issuance of capital stock of the Company or 20% or more of the consolidated total assets of the Company and the Company Subsidiaries, in a single transaction or a series of related transactions.

“Superior Proposal” means any Takeover Proposal (with the percentages set forth in such definition changed from 20% to 50%) the Board of Directors of the Company determines in good faith, after consultation with its outside counsel and a financial advisor of nationally recognized reputation, (x) would result in a transaction that if consummated, would be more favorable to the shareholders of the Company than the Merger, taking into account all of the terms and conditions of such proposal and of this Agreement (including any proposal by Parent to amend the terms of this Agreement), and (y) is reasonably capable of being consummated on the terms so proposed, taking into account all financial, regulatory, legal and other aspects of such proposal.

Section 6.4. Access to Information. Subject to applicable Law, the Company shall, and shall cause the Company Subsidiaries to, afford to the officers, directors, employees, accountants, counsel, financial advisors, consultants, financing sources and other advisors or representatives (collectively, “Representatives”) of Parent reasonable access during normal business hours throughout the period prior to the Effective Time to all of the Company’s and the Company Subsidiaries’ properties, books, records, contracts, commitments and personnel, and shall furnish, and shall cause to be furnished, as promptly as practicable to Parent such information as Parent may reasonably request, provided 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 information provided by the Company shall be governed by the terms of the Confidentiality Agreement. No investigation pursuant to this Section 6.4 shall affect the representations, warranties or conditions to the obligations of the parties contained herein.

Section 6.5. Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement, each of the Company, Parent and Merger Sub will use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under this Agreement and applicable Laws and regulations to consummate the Merger and the other transactions contemplated by this Agreement as promptly as practicable after the date of this Agreement, including (i) preparing and filing as promptly as practicable all documentation to effect all necessary applications, notices, petitions, filings and other documents and to obtain as promptly as practicable all consents, clearances, waivers, licenses, orders, registrations, approvals, permits and authorizations necessary or advisable to be obtained from any third party and/or any Governmental Entity in order to consummate the Merger or any of the other transactions contemplated by this Agreement and (ii) taking all reasonable steps as may be necessary or advisable to make all necessary filings and obtain all such consents, clearances, waivers, licenses, registrations, permits, authorizations, orders and approvals (including providing all necessary information and documentary material and providing personnel as necessary to attend any regulatory meetings, hearings or other proceedings). In furtherance and not in limitation of the foregoing, each of the Company and Parent agrees to make, as promptly as practicable after the date of this Agreement, (A) an appropriate filing of a Notification and Report Form pursuant to the HSR Act, (B) appropriate filings required by the Transaction Approvals and (C) all other necessary filings with any other Governmental Entity with respect to the transactions contemplated hereby and to supply as promptly as practicable any additional information and documentary material that may be requested pursuant to such requirements and to use its reasonable best efforts to cause the

expiration or termination of the applicable waiting periods under the HSR Act in the most expeditious manner practicable. Notwithstanding the foregoing, neither Parent nor the Company shall, and shall cause their respective Representatives not to, participate in any meeting with any Governmental Entity in connection with the Transaction Approvals unless it consults with the other party in advance and gives the other party the opportunity to attend or participate to the extent permitted by such Governmental Entity. The Company and Parent will each request early termination of the waiting period with respect to the Merger under the HSR Act.

(b) To the extent permissible under applicable Law or any rule, regulation or restriction of a Governmental Entity, each of the Company and Parent shall, in connection with the efforts referenced above to obtain all requisite material approvals, clearances and authorizations for the transactions contemplated by this Agreement under the HSR Act or any other approval of a Governmental Entity, use its reasonable best efforts to (i) cooperate in all respects with each other in connection with any filing or submission and in connection with any investigation or other inquiry, including any proceeding initiated by a private party, (ii) promptly inform the other party of any communication received by such party from, or given by such party to, the Antitrust Division of the Department of Justice (the “DOJ”), the Federal Trade Commission (the “FTC”) or any other Governmental Entity and of any material communication received or given in connection with any proceeding by a private party, in each case regarding any of the transactions contemplated hereby, and provide to the other party, in advance of filing, all filings and submissions to be made by such party, such that the other party has a reasonable opportunity to comment thereon, such comments to be taken into account by the filing party, (iii) permit the other party, or the other party’s legal counsel, to review any communication given by it to, and consult with each other in advance of any meeting or conference with, the DOJ, the FTC or any such other Governmental Entity or, in connection with any proceeding by a private party, with any other Person and (iv) to the extent permitted by such Governmental Entity or other Person, give the other party the opportunity to attend and participate in such meetings and conferences.

(c) If any objections are asserted with respect to the transactions contemplated hereby under any applicable Law or if any suit is instituted by any Governmental Entity or any private party challenging any of the transactions contemplated hereby as violative of any applicable Law, each of the Company and Parent shall use its reasonable best efforts to resolve any such objections or challenge as such Governmental Entity or private party may have to such transactions under such applicable Law so as to permit consummation of the transactions contemplated by this Agreement on the terms and conditions set forth in this Agreement.

Section 6.6. Employee Matters.

(a) Until the second anniversary of the Effective Time (the “Benefits Continuation Period”), the Surviving Corporation and its Affiliates shall provide, or

cause to be provided, for those employees of the Company and the Company Subsidiaries who continue as employees of the Company, the Company Subsidiaries or the Surviving Corporation during the Benefits Continuation Period, compensation (acknowledging this includes reference to base salary and incentive compensation) and employee benefits that are substantially comparable in the aggregate to those provided by the Company or the applicable Company Subsidiary to such employees immediately before the date of this Agreement (it being understood that neither the Surviving Corporation nor any of its Affiliates will have any obligation to provide any equity-based arrangements). The provisions of this Section 6.6 shall not create in any current or former employee of the Company or any Company Subsidiary any rights to employment or continued employment with Parent, the Company or any of their respective Subsidiaries or any right to any specific terms or conditions of employment. Nothing herein shall be deemed to be a guarantee of employment for any current or former employee of the Company or any of its Subsidiaries, or to restrict the right of Parent or the Surviving Corporation to terminate any such employee.

(b) The Surviving Corporation and its Affiliates shall (i) waive any applicable pre-existing condition exclusions and waiting periods with respect to participation and coverage requirements in any replacement or successor welfare benefit plan of the Surviving Corporation (except for the short and long term disability benefit plans of the Surviving Corporation or any of its Affiliates, which plans, however, will recognize prior service for purposes of meeting the time requirements in those plans’ preexisting condition exclusions) that an employee of the Company or any Company Subsidiary is eligible to participate in following the Effective Time to the extent such exclusions or waiting periods were inapplicable to, or had been satisfied by, such employee immediately prior to the Effective Time under the analogous Company Benefit Plan in which such employee participated, (ii) provide each such employee with credit for any co-payments and deductible paid prior to the Effective Time (to the same extent such credit was given under the analogous Company Benefit Plan prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements and (iii) recognize service prior to the Effective Time with the Company and the Company Subsidiaries for purposes of eligibility to participate, vesting and level of benefits (but not for any other purpose) under any employee benefit plan of the Surviving Corporation or its Affiliates, to the same extent such service was recognized by the Company and the Company Subsidiaries under any similar Company Benefit Plan (including vacation) in which such employee participated immediately prior to the Effective Time; provided that (x) the Surviving Corporation and its Affiliates shall not be obligated to provide credit for benefit accrual purposes under any defined benefit pension plan sponsored by the Surviving Corporation or its Affiliates for service prior to the date on which the employee actually becomes a participant in such plan, except that the Liberty Mutual Retirement Benefit Plan will give such employees credit for prior service with the Company and the Company Subsidiaries after June 30, 2004 for benefit accrual purposes, (y) with respect to any health plan of the Surviving Corporation or any of its Affiliates which provides

post-retirement coverage (other than Company Benefit Plans in which such employee participated prior to the Effective Time), the Surviving Corporation will recognize service only for periods of an employee’s employment with Surviving Corporation or its Subsidiaries after the Effective Time (except that (A) with respect to Parent’s or its Affiliates’ pre-age 65 retiree health program, employees of the Company and the Company Subsidiaries with at least 25 years of service as of July 1, 2004 and retired employees of the Company and the Company Subsidiaries as of July 1, 2004 will receive credit for periods of an employee’s employment with the Company and the Company Subsidiaries prior to the Effective Time for purposes of eligibility and cost sharing, (B) with respect to Parent’s or its Affiliates’ post-age 65 retiree health program, retired employees of the Company and the Company Subsidiaries as of July 1, 2004 will receive cost sharing at the lowest level for which retirees are eligible under such program, (C) with respect to Parent’s or its Affiliates’ post-age 65 retiree health program, employees of the Company and the Company Subsidiaries with at least 25 years of service as of July 1, 2004 will receive credit for periods of an employee’s employment with the Company and the Company Subsidiaries prior to the Effective Time for purposes of eligibility and Parent or its Affiliates will give such employees credit for prior service with the Company and the Company Subsidiaries after June 30, 2004 for purposes of cost sharing (provided that upon retirement such employees will receive cost sharing which is no lower than the lowest level for which retirees are eligible under such program), and (D) with respect to Parent’s or its Affiliates’ pre-age 65 and post-age 65 retiree health programs, employees of the Company and the Company Subsidiaries with less than 25 years of service as of July 1, 2004 will receive credit for periods of an employee’s employment with the Company and the Company Subsidiaries prior to the Effective Time for purposes of eligibility and Parent or its Affiliates will give such employees credit for prior service with the Company and the Company Subsidiaries after June 30, 2004 for purposes of cost sharing, and (z) the foregoing provisions of this Section 6.6(b) shall not apply to the extent it would result in any duplication of benefits for the same period of service (except that this subclause (z) will not limit the additional incremental benefit accrual provided under subclause (x) above).

(c) With respect to matters described in this Section 6.6, the Company shall consult with Parent (and consider in good faith the advice of Parent) prior to sending any material notices or other material communication materials to its employees or former employees. Prior to the Effective Time, subject to applicable Law, the Company shall provide Parent with reasonable access to such employees or former employees for purposes of Parent providing reasonable notices or other communication materials regarding Parent compensation and benefit plans and the matters described in this Section 6.6, provided that such notices or other communication materials are reasonably approved in advance by the Company.

(d) Parent shall cause the Surviving Corporation and any successor thereto to honor, fulfill and discharge the Company’s and its Subsidiaries’ obligations under the agreements identified in Section 6.6(d) of the Company Disclosure Schedule.

Following the payment of pro rata bonuses as provided in the preceding sentence (the “Pro Rata Bonus”), Parent will cause the Company to (A) maintain a bonus plan for the remainder of year in which the Effective Time occurs on the same terms and conditions and pursuant to the same targets and performance measures as were in effect for such year and (B) pay bonuses within two and a half months following the end of such year or such later time as provided in the applicable Bonus Plan in an amount equal to the excess, if any, of (i) the annual bonus which would have been earned by the participants for the entire calendar year under the bonus plan described in clause (A) above over (ii) any Pro Rata Bonus previously paid in respect of such year. If the Effective Time occurs in 2008, the Company shall be permitted, prior to the Effective Time, to pay annual bonuses for 2007 in an amount equal to the annual bonus earned by participants for the 2007 calendar year.

(f) Parent hereby acknowledges that a “change in control” or “change of control” within the meaning of each Company Benefit Plan listed in Section 6.6(f) of the Company Disclosure Schedule will occur upon the Effective Time.

Parent, Merger Sub and the Company acknowledge and agree that all provisions contained in this Section 6.6 with respect to employees of the Company and its Subsidiaries are included for the sole benefit of Parent, Merger Sub and the Company, and that nothing herein, whether express or implied, shall create any third party beneficiary or other rights (i) in any other person, including any current or former employees of the Company or any of its Subsidiaries, any participant in any Company Benefit Plan, or any dependent or beneficiary thereof, or (ii)

to continued employment with Parent, the Surviving Corporation, or any of their respective affiliates or continued participation in any Company Benefit Plan.

Subject to Section 8.3, whether or not the Merger is consummated, all Expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such Expenses.

Section 6.10. Directors’ and Officers’ Indemnification and Insurance.

(a) From and after the Effective Time, each of Parent and the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, indemnify and hold harmless, to the fullest extent permitted under applicable law (and Parent and the Surviving Corporation shall also advance expenses as incurred to the fullest extent permitted under applicable law; provided 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), each present and former director and officer of the Company and the Company Subsidiaries (collectively, the “Indemnified Parties”)

against any costs or expenses (including attorneys’ fees), judgments, 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 or pertaining to matters existing or occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement, whether asserted or claimed prior to, at or after the Effective Time.

(b) Prior to the Effective Time, the Company shall, and if the Company is unable to Parent shall cause the Surviving Corporation as of the Effective Time to, fully pay the premium for “tail” insurance policies for the extension of (i) the Side A coverage part (directors’ and officers’ liability) of the Company’s existing directors’ and officers’ insurance policies, and (ii) the Company’s existing fiduciary liability insurance policies, in each case for a claims reporting or discovery period of at least six years from and after the Effective Time from an insurance carrier rated at least “A” by A.M.

Takeover Proposal or publicly announced intention shall not have been publicly withdrawn without qualification at least ten (10) days prior to the Outside Date, and (B) this Agreement is terminated thereafter by either Parent or the Company pursuant to Section 8.1(b)(i); or

(iv) Section 8.1(b)(iii) if (A) after the date of this Agreement any Person or “group” (within the meaning of section 13(d)(3) of the Exchange Act) publicly makes or publicly announces an intention to make a Takeover Proposal prior to the Company obtaining the Company Shareholder Approval and such Takeover Proposal or publicly announced intention shall not have been publicly withdrawn without qualification at least five (5) Business Days prior to the vote of the shareholders with respect to the Merger, and (B) this Agreement is terminated thereafter by either Parent or the Company pursuant to Section 8.1(b)(iii).

(b) If the Company is required to pay Parent a Termination Fee, such Termination Fee shall be payable not later than two Business Days after termination of this Agreement (except with respect to Section 8.1(d)(ii) or Section 8.1(d)(iii), which shall be paid as set forth in Section 8.1(d)(ii) or Section 8.1(d)(iii)), in each case by wire transfer of immediately available funds to an account designated by Parent.

If this Agreement is terminated under the circumstances described in Section 8.3(a)(iii) or 8.3(a)(iv), the Company shall reimburse Parent and Merger Sub for all of their reasonable and documented Expenses, up to a maximum amount of $5 million (the “Parent Expenses”), within three Business Day of receipt of written notice from Parent requesting payment thereof.

(c) The parties each agree that the agreements contained in this Section 8.3 are an integral part of the transaction contemplated by this Agreement, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if the Company fails promptly to pay any amounts due under this Section 8.3 and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company for such amounts, the Company shall pay interest on such amounts from the

date payment of such amounts were due to the date of actual payment at the rate of interest published from time to time in The Wall Street Journal, Eastern Edition (or any successor publication thereto), designated therein as the prime rate on the date such payment was due, together with the costs and expenses of Parent (including reasonable legal fees and expenses) in connection with such suit.

Section 9.3. Interpretation.

(a) When a reference is made in this Agreement to a Section, Exhibit or Schedule, such reference shall be to a Section of or Exhibit or Schedule to this

Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. 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.

Section 9.4. Counterparts; Effectiveness. This Agreement may be executed in two or more counterparts, including by facsimile, each of which shall be deemed to be an original but all of which shall constitute one and the same instrument. This Agreement shall become effective when each party hereto has received counterparts thereof signed and delivered (by telecopy or otherwise) by all of the other parties hereto.

Section 9.5. Entire Agreement; No Third Party Beneficiaries.

(a) This Agreement (including the Exhibits and Schedules) constitutes the entire agreement, and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and thereof. EACH PARTY HERETO AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, NEITHER PARENT AND MERGER SUB NOR THE COMPANY MAKES ANY OTHER REPRESENTATIONS OR WARRANTIES, AND EACH HEREBY DISCLAIMS ANY OTHER REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, OR AS TO THE ACCURACY OR COMPLETENESS OF ANY OTHER INFORMATION, MADE BY, OR MADE AVAILABLE BY, ITSELF OR ANY OF ITS REPRESENTATIVES, WITH RESPECT TO, OR IN CONNECTION WITH, THE NEGOTIATION, EXECUTION OR DELIVERY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, NOTWITHSTANDING THE DELIVERY OR DISCLOSURE TO THE OTHER OR THE OTHER’S REPRESENTATIVES OF ANY DOCUMENTATION OR OTHER INFORMATION WITH RESPECT TO ANY ONE OR MORE OF THE FOREGOING.

(b) This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and, except as provided in Section 6.10, nothing in this Agreement, express or implied, is intended to or shall confer upon any Person not a party to this Agreement any rights, benefits or remedies of any nature whatsoever; except that the Company shall have the right to recover, solely through an action brought by the Company, damages from Parent in the event of a willful or intentional breach of this Agreement by Parent, in which event the damages recoverable by the Company for itself

and on behalf of the shareholders shall be determined by reference to the total amount that would have been recoverable by the Company’s shareholders if all such shareholders brought an action against Parent and were recognized as third party beneficiaries hereunder. The parties hereto further agree that the rights of third party beneficiaries under Section 6.10 shall not arise unless and until the Effective 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 9.9 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.

Section 9.6. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Section 9.7. Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the other parties, and any attempt to make any such assignment without such consent shall be null and void, except that (i) Merger Sub may assign, in its sole discretion, any or all of its rights, interests and obligations under this Agreement to any wholly owned Subsidiary of Parent without the consent of the Company 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 contemplated by this Agreement or otherwise materially impede the rights of the shareholders of the Company under this Agreement. Any purported assignment in violation of this Agreement is void.

Section 9.8. Amendment. This Agreement may be amended by the parties, by action taken or authorized by their respective Boards of Directors, at any time before or after the Company Shareholder Approval is obtained, but after such approval no amendment shall be made which by Law or in accordance with the rules of any relevant stock exchange requires further approval by the Company’s shareholders without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties.

Section 9.9. Extension; Waiver. At any time prior to the Effective Time, the parties, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Section 9.10. Governing Law and Venue; Waiver of Jury Trial.

(a) All disputes, claims or controversies arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the transactions contemplated hereby shall be governed by and construed in accordance with the laws of the State of Ohio without regard to its rules of conflict of laws.

(b) Except as set out below, each of the Company, Parent and Merger Sub hereby irrevocably and unconditionally consents to submit to the sole and exclusive jurisdiction of the courts of the State of Ohio or any court of the United States located in the State of Ohio (the “Ohio Courts”) for any litigation arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the transactions contemplated hereby (and agrees not to commence any litigation relating thereto except in such courts), waives any objection to the laying of venue of any such litigation in the Ohio Courts and agrees not to plead or claim in any Ohio Court that such litigation brought therein has been brought in an inconvenient forum. Each of the parties hereto agrees that service of process may be made on such party by prepaid certified mail with a proof of mailing receipt validated by the United States Postal Service constituting evidence of valid service. Service made pursuant to the immediately preceding sentence shall have the same legal force and effect as if served upon such party personally within the State of Ohio. In the event any party hereto fails to notify any other party hereto of its agent for service of process in the State of Ohio, nothing herein contained shall be deemed to affect the right of any party hereto to serve process in any manner permitted by Law or to commence legal proceedings or otherwise proceed against any other party

hereto in any other jurisdiction to enforce judgments obtained in any action, suit or proceeding brought pursuant to this Section 9.10.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10(c).

Section 9.11. Enforcement. The parties agree that irreparable damage would occur in the event that any provision of this Agreement was not performed by the Company in accordance with its specific terms or was otherwise breached by the Company. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the Courts of the State of Ohio, this being in addition to any other remedy to which they are entitled at law or in equity.
