WHEREAS, Parent, Subsidiary and the Company wish to provide for a merger of Subsidiary with and into the Company (the "Merger"), upon the terms and subject to the conditions set forth in this Agreement and in accordance with the applicable provisions of the Massachusetts Business Corporation Act (the "MBCA"), whereby all of the issued and outstanding shares of common stock, par value $0.50 per share, of the Company (the "Company Common Stock") issued and outstanding immediately prior to the Effective Time (as hereinafter defined), other than (i) the shares of Company Common Stock owned directly or indirectly by Parent, Subsidiary or the Company and (ii) to the extent appraisal rights are available under the MBCA, any shares of Company Common Stock ("Dissenting Shares") held by record holders or beneficial owners of shares of Company Common Stock who duly satisfy the applicable requirements of the MBCA for the exercise of appraisal rights and to obtain payment of the fair value for their shares ("Dissenting Shareholders"), will be converted into the right to receive $36.70 per share in cash (the "Common Stock Consideration");

WHEREAS, the Board of Directors of Parent has unanimously approved, and the respective Boards of Directors of each of Subsidiary and the Company have unanimously adopted, this Agreement; and

WHEREAS, Parent, Subsidiary and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Merger;

Section 1.2 Effective Time of the Merger. The Merger shall become effective at the time (such time, the "Effective Time") of the filing of articles of merger (in the form required by, and executed in accordance with, the relevant provisions of the MBCA) with the Secretary of State of the Commonwealth of Massachusetts in accordance with the MBCA (the "Merger Filing"). The Merger Filing shall be made simultaneously with or as promptly as practicable following the Closing.

Section 1.3 Effects of the Merger. The Merger shall have the effects set forth in the applicable provisions of the MBCA, including Section 11.07.

ARTICLE III

EFFECT OF THE MERGER ON THE STOCK OF THE CONSTITUENT
CORPORATIONS; SURRENDER OF CERTIFICATES

Section 3.1 Conversion of Company Common Stock in the Merger. At the Effective Time, by virtue of the Merger and without any further action on the part of any holder of any capital stock of Parent, Subsidiary or the Company:

(a) each previously-issued share of Company Common Stock that remains outstanding immediately prior to the Effective Time, other than any shares required to be canceled pursuant to Section 3.1(b) and any Dissenting Shares, shall be converted into the right to receive the Common Stock Consideration, payable to the holder thereof, in each case without interest, upon surrender of the certificate formerly representing such share of the Company Common Stock and such other documents as reasonably may be required in accordance with Section 3.3, and all such shares of Company Common Stock, when so converted, no longer shall be outstanding and automatically shall be cancelled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Company Common Stock (a "Company Certificate") shall cease to have any rights with respect thereto, except the right to receive the Common Stock Consideration per share therefor, without interest, upon the surrender of such certificate in accordance with Section 3.3 or to perfect any rights of appraisal as a holder of Dissenting Shares that such holder may have pursuant to the MBCA, as well as the right to receive any unpaid dividend with respect to the Company Common Stock with a record date occurring prior to the Effective Time and each holder of shares of Company Common Stock issued in uncertificated form similarly shall cease to have any rights with respect thereto, except the right to receive the Common Stock Consideration per share therefor, without interest, upon compliance with the requirements of Section 3.3 or to perfect any rights of appraisal as a holder of Dissenting Shares that such holder may have pursuant to the MBCA, as well as the right to receive any unpaid dividend with respect to the Company Common Stock with a record date occurring prior to the Effective Time; and

(b) each share of Company Common Stock of the Company, if any, owned of record or beneficially, directly or indirectly, by Parent or Subsidiary or held in treasury by the Company or any subsidiary of the Company (each a "Company Subsidiary") immediately prior to the Effective Time (other than shares held in a fiduciary capacity) automatically shall be canceled and retired and shall cease to exist and no cash or other consideration shall be delivered or deliverable in exchange therefor.

Section 3.2 Conversion of Subsidiary Shares. At the Effective Time, by virtue of the Merger and without any further action on the part of Parent as the sole shareholder of Subsidiary, each issued and outstanding share of common stock, par value $0.10 per share, of Subsidiary that is issued and outstanding prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.50 per share, of the Surviving Corporation.

Section 3.3 Surrender and Exchange of Certificates.

(a) Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as paying agent in the Merger (the "Paying Agent"), and from and after the Effective Time Parent shall deposit or cause to be deposited with the Paying Agent cash in an amount equal to the aggregate amounts payable under Sections 3.1(a) and 3.5.

(b) As soon as reasonably practicable after the Effective Time but in no event later than five (5) business days after the date thereof, Parent shall cause the Paying Agent to mail to each holder of record of Company Common Stock (each an "Effective Date Holder") whose shares were converted into

<PAGE> 3

the right to receive the Common Stock Consideration pursuant to Section 3.1(a), (i) a letter of transmittal in customary form for transactions of this nature (which shall specify that for holders of shares not issued in uncertificated form, delivery of such holder's Company Certificates shall be effected, and risk of loss and title to the Company Certificates shall pass, only upon actual delivery of the Company Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent reasonably may specify), and (ii) instructions for use in effecting the surrender of the Company Certificates in exchange for the Common Stock Consideration and instructions for use by holders of shares issued in uncertificated form. Upon delivery to the Paying Agent of a duly executed letter of transmittal and such other documents as the Paying Agent shall reasonably require, including where applicable delivery of Company Certificates, each Effective Date Holder shall be entitled to receive in exchange therefor the Common Stock Consideration for each share of Company Common Stock covered by the letter of transmittal, in accordance with Section 3.1(a), and the Company Certificates so surrendered shall be canceled. If a transfer of ownership of Company Common Stock has occurred but has not been registered in the transfer records of the Company, a check representing the proper amount of Common Stock Consideration may be issued to the transferee if the Company Certificate representing such shares of Company Common Stock is presented to the Paying Agent accompanied by all documents and endorsements required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as provided in this Section 3.3, each Company Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Common Stock Consideration for each share of Company Common Stock represented thereby. No interest will be paid or accrue on any amounts payable upon surrender of any Company Certificate.

(c) Promptly following the date that is twelve months after the Effective Time, the Paying Agent shall deliver to Parent all cash and any documents in its possession or control relating to the transactions described in this Agreement, and the Paying Agent's duties shall terminate. Thereafter, each holder of a Company Certificate may surrender such Company Certificate to the Surviving Corporation or Parent and (subject to applicable abandoned property, escheat or other similar laws) receive in exchange therefor the Common Stock Consideration, payable upon due surrender of the Company Certificate without any interest thereon.

(d) If any Company Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Company Certificate to be lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Company Certificate the Common Stock Consideration deliverable in respect thereof determined in accordance with this Article III; provided, however, that Parent or the Paying Agent may, in its discretion, require the delivery of an indemnity or bond in customary amount against any claim that may be made against the Surviving Corporation with respect to such Company Certificate or ownership thereof.

(e) The Paying Agent shall invest any funds held by it for purposes of this Section 3.3 as directed by Parent, on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent. To the extent that there are losses with respect to any such investments, Parent shall be responsible to ensure that the Paying Agent has access to funds sufficient to make any required payments under this Article III promptly when due.

(f) None of Parent, Subsidiary, the Company, the Surviving Corporation or the Paying Agent shall be liable to any person in respect of any cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Company Certificates shall not have been surrendered prior to two years after the Effective Time (or immediately prior to such earlier date on which any of the Common Stock Consideration would otherwise escheat or become the property of any federal, state, local, municipal or foreign government, whether national, regional or local, any instrumentality, subdivision, court, self-regulatory organization, administrative agency or commission or other authority

<PAGE> 4

thereof, or any quasi-governmental or private body exercising any regulatory, taxing or other governmental or quasi-governmental authority (any of the foregoing, a "Governmental Authority"), any amounts payable in respect thereof shall, to the extent permitted by law, become the property of the Surviving Corporation, free and clear of all claims or interest on any person previously entitled thereto.

Section 3.4 Closing of the Company's Transfer Books. At the Effective Time, holders of Company Certificates shall cease to have any rights as shareholders of the Company, and the Company Share Certificates shall represent solely the right to receive the Common Stock Consideration and, if applicable, any unpaid dividends, pursuant to Section 3.1, without interest. At the Effective Time, the stock transfer books of the Company shall be closed and no transfer of shares of Company Common Stock that were outstanding immediately prior to the Effective Time shall thereafter be made. If, after the Effective Time, subject to the terms and conditions of this Agreement, Company Certificates formerly representing shares of Company Common Stock are presented to the Surviving Corporation, they shall be canceled and exchanged for the Common Stock Consideration in accordance with this Article III.

Section 3.5 Options; Restricted Stock Units.

(a) At the Effective Time, each option, warrant or other similar right (other than Restricted Stock Units, which are addressed in paragraph (b) of this Section 3.5) to acquire shares of Company Common Stock (each an "Option") that then remains outstanding and originally was granted under any Company Plan (but not including options ("ACIC Options") issued under the American Commerce Agents Plan), whether or not then vested or exercisable, automatically shall be terminated at the Effective Time and converted into the right of the holder thereof to receive thereupon in full satisfaction of such Option as of the Effective Time, an amount in cash (subject to any applicable withholding Taxes) equal to the product of (x) the excess, if any, of the Common Stock Consideration over the applicable exercise price of such Option and (y) the number (determined without reference to vesting requirements or other limitations on exercisability) of shares of Company Common Stock issuable upon exercise of such Option (the "Option Consideration").

(b) At the Effective Time, each issued and outstanding restricted stock unit (whether vested or unvested) granted under any Company Plan (the "Restricted Stock Units") pursuant to the terms of a Restricted Stock Unit Agreement between the Company and a holder thereof (each, an "RSU Agreement") shall be terminated and converted into the right to receive the Common Stock Consideration payable with respect to the number of shares of Company Common Stock represented by such unit (the "RSU Consideration"). The cash payment in lieu of Company Common Stock pursuant to this Section 3.5(b), together with any Dividend Equivalent Payment (as defined in the RSU Agreement) that is owed as of the Effective Time, less any required withholding Taxes on such Dividend Equivalent Payment, shall be paid to each Participant (as defined in the RSU Agreement) (or, if applicable, the Participant's designated beneficiary or legal representative) in accordance with Section 3.5(e).

(c) The Options and the Restricted Stock Units are collectively referred to herein as the "Equity Awards." The aggregate Option Consideration and RSU Consideration payable pursuant to Sections 3.3(a) and 3.3(b) is referred to herein as the "Equity Award Consideration." Prior to the date of this Agreement, the Company, the Board of Directors of the Company and the compensation committee of the Board of Directors of the Company, as applicable, have adopted such resolutions and taken or caused to be taken all such other action, if any, as may be required to effectuate the treatment of Equity Awards provided for in this Section 3.5.

(d) At the Effective Time, each issued and outstanding ACIC Option automatically shall be converted into the right to acquire upon exercise (subject to satisfaction of all vesting and other conditions to exercise, which shall remain in full force and effect), an amount in cash for each share of Company

<PAGE> 5

Common Stock otherwise issuable upon such exercise but for the conversion provided for in this paragraph equal to the excess of (x) the Common Stock Consideration over (y) the exercise price per share of such ACIC Option (the "Agent Option Payment"). Following the Effective Time, the Agent Option Payment with respect to each ACIC Option referenced in the immediately preceding sentence shall be paid by the Surviving Corporation to the applicable person on the applicable Confirmation Date (as such term is defined in the applicable Agent Option Agreement between the Company, or any of its Subsidiaries, and the holder thereof), provided that all terms and conditions of such Agent Option Agreement have then been satisfied. For the avoidance of doubt, it is the intention of Parent and the Company that (i) any ACIC Option that is outstanding immediately prior to the Effective Time and has an exercise price greater than the Merger Consideration shall expire without the right to receive any Company Common Stock or any payment in lieu thereof and (ii) no acceleration of the exercisability of any ACIC Option shall occur by reason of the Merger.

(e) As soon as reasonably practicable after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of an Equity Award immediately prior to the Effective Time, a check in an amount equal to the Equity Award Consideration due and payable to such holder pursuant to Sections 3.5(a) and 3.5(b) in respect of such Equity Award.

Section 3.6 Tax Withholding. 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 former holder of shares of Company Common Stock, Options, Restricted Stock Units or ACIC Options such amounts as Parent or the Surviving Corporation is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the "Code"), or any other provision of federal, state, local or foreign tax law. To the extent that amounts are so withheld by Parent or the Surviving Corporation, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the former holder of the shares of Company Common Stock, Options, Restricted Stock Units or ACIC Options in respect of which such deduction and withholding was made by Parent or the Surviving Corporation.

Section 3.7 Dissenting Shares.

(a) Notwithstanding any provision of this Agreement to the contrary, any Dissenting Shares held by a Dissenting Shareholder shall not be converted into the Common Stock Consideration but shall become the right to receive such consideration as may be determined to be due to such Dissenting Shareholder pursuant to the MBCA; provided, however, that each share of Company Common Stock outstanding immediately prior to the Effective Time and held by a Dissenting Shareholder who, after the Effective Time, withdraws his demand or fails to perfect or otherwise loses his right of appraisal, pursuant to the MBCA, shall be deemed to be converted as of the Effective Time into the right to receive the Common Stock Consideration, without interest.

(b) The Company shall give Parent (i) prompt notice of any demands for appraisal pursuant to the applicable provisions of the MBCA received by the Company, attempted withdrawals of such demands, and any other instruments served pursuant to the MBCA and received by the Company relating to rights of appraisal and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal under the MBCA. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any such demands for appraisal, or settle, or offer to settle, or otherwise negotiate any such demands for appraisal.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company represents and warrants to Parent and Subsidiary that, except as set forth in the written disclosure schedule delivered by the Company to Parent prior to the execution and delivery of this Agreement (the "Company Disclosure Schedule"), which identifies exceptions only by the specific section or subsection to which each entry relates, it being acknowledged and agreed by Parent, however, that any matter set forth in any section or subsection of the Company Disclosure Schedule shall be deemed to be a disclosure for all purposes of this Agreement and all other sections or subsections of the Company Disclosure Schedule to which it is reasonably apparent that the matters so disclosed are applicable, but shall expressly not be deemed to constitute an admission by the Company or any of its Subsidiaries, or otherwise imply, that any such matter rises to the level of a Company Material Adverse Effect (as defined below) or is otherwise material for purposes of this Agreement or the Company Disclosure Schedule.

Section 4.1 Organization and Qualification. The Company and each of the Company Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization and has all requisite corporate power and authority to own, license, use, operate, lease or otherwise hold its assets and properties and to carry on its business as it is now being conducted. The Company has made available to Parent complete and correct copies of its articles of organization and bylaws and the certificate of incorporation and bylaws (or similar organizational documents) of each Company Subsidiary. The Company and each Company Subsidiary is duly qualified or licensed to transact business and is in good standing in each jurisdiction in which the assets or property owned, licensed, used, leased or operated by it or the nature of the business conducted by it makes such qualification or licensing necessary, except where the failure to be so duly qualified or licensed and in good standing would not have a Company Material Adverse Effect. As used in this Agreement, a "Company Material Adverse Effect" means an event, circumstance, change or effect that has a material adverse effect on the business, assets, financial condition or results of operations of the Company and its subsidiaries, taken as a whole; provided, however, that none of the following shall constitute or be taken into account in determining whether there has been or is a Company Material Adverse Effect: (1) changes in the economy of, or financial or securities markets generally in, the United States or any other country or countries, except to the extent such changes have a disproportionate impact on the Company and its Subsidiaries, taken as a whole, relative to other industry participants; (2) the consequences of natural catastrophes or acts of war or terrorism, except to the extent such changes have an impact on the Company and its Subsidiaries, taken as a whole, that is disproportionate to the Company's share in any relevant market; (3) any material adverse effects resulting from the announcement or the pendency of the transactions contemplated by this Agreement, including any loss or threatened loss of business from any agents, brokers or customers of the Company or any of its Subsidiaries; (4) changes in any Law, United States generally accepted accounting principles ("GAAP") or statutory accounting principles ("SAP") or any interpretation thereof after the date hereof; including accounting pronouncements by the SEC, the National Association of Insurance Commissioners and the Financial Accounting Standards Board; (5) any failure by the Company to meet any estimates of revenues or earnings for any period ending on or after the date of this Agreement; provided, however, that the exception in this clause (5) shall not prevent or otherwise affect a determination that any change, effect, circumstance or development underlying such failure has resulted in, or contributed to, a Company Material Adverse Effect; (6) a decline in the price or trading volume of the Company Common Stock on the New York Stock Exchange; provided, however, that the exception in this clause (6) shall not prevent or otherwise affect a determination that any change, effect, circumstance or development underlying such decline has resulted in, or contributed to, a Company Material Adverse Effect; (7) any occurrence or condition affecting the property and casualty insurance or reinsurance industry generally (including without limitation any change or proposed change

<PAGE> 7

in applicable state Laws regulating the business of insurance (collectively, "Insurance Laws")), except to the extent such occurrences or conditions have an impact on the Company and its Subsidiaries, taken as a whole, that is disproportionate to the Company's share in any relevant market; (8) any increase in competition, whether from new entrants or existing competitors in any market in which the Company or its Subsidiaries operate and/or (9) any actual or proposed change in the prevailing legislative or regulatory environment for insurance in Massachusetts, including, without limitation, any change in, development or interpretation of, or promulgation of rules or regulations under, any Law, including any change pursuant to any administrative order, interpretation, bulletin or other formal or informal regulatory guidance.

Section 4.2 Capitalization.

(a) The authorized capital stock of the Company consists solely of 100,000,000 shares of Company Common Stock and 5,000,000 shares of preferred stock, par value $1.00 per share.

Parent and Subsidiary are (i) in compliance with the terms of their respective certificate or articles of organization, bylaws or other charter or organizational documents and (ii) in compliance with all Laws except to the extent any non-compliance, individually or in the aggregate, would not reasonably be expected to have a Parent Material Adverse Effect.

Section 5.5 Information Supplied. None of the information to be provided by Parent or Subsidiary for inclusion in the Proxy Statement will contain any untrue statement of a material fact or omit to state any material fact required to be stated in any such document or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

As of the Closing, Parent will have sufficient funds to consummate the Merger and the other transactions contemplated hereby, and to satisfy its and Subsidiary's obligations under this Agreement, including, without limitation, the obligation to deliver to the Paying Agent cash in immediately available funds equal to the aggregate Common Stock Consideration and Equity Award Consideration pursuant to Article III and to consummate the Merger and other transactions contemplated hereby and to pay all of Parent's and Subsidiary's related fees and expenses.

Section 6.2 Reasonable Best Efforts to Consummate.

(a) Subject to the terms and conditions of this Agreement, each of the parties hereto shall (and shall cause its respective subsidiaries, if any, to) use all 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 applicable laws and regulations to consummate and make effective the Merger and the other transactions contemplated by this Agreement as promptly as practicable, including using its reasonable best efforts to (i) prepare, execute and deliver such instruments and take or cause to be taken such actions as any other party shall reasonably request, and (ii) after consultation with the other parties, obtain any consent, waiver, approval or authorization from any third party required in order to maintain in full force and

<PAGE> 29

effect any of the Company Permits or the Company's contracts, licenses or other rights following the Merger and the other transactions contemplated by this Agreement.

(b) Without limiting the generality of anything contained in Section 6.2(a) or elsewhere in this Agreement, each of the parties undertakes and agrees to file as promptly as practicable following the execution and delivery of this Agreement, and in any event within twenty business days after the date hereof, a Notification and Report Form under the HSR Act with the United States Federal Trade Commission (the "FTC") and the United States Department of Justice, Antitrust Division (the "Antitrust Division") and as promptly or reasonably practicable to make all other required Antitrust Filings. Each of the parties shall (i) respond as promptly as practicable to any inquiries received from the FTC, the Antitrust Division or other applicable Governmental Authorities for additional information or documentation and to all inquiries and requests received from any State Attorney General or other Governmental Authority; and (ii) not extend any waiting period under the HSR Act and other applicable antitrust or competition laws, rules or regulations or enter into any agreement with the FTC, the Antitrust Division or other applicable Governmental Authorities not to consummate the transactions contemplated by this Agreement, except with the prior written consent of the other parties hereto. Parent shall use its best efforts to avoid or eliminate each and every impediment under any antitrust, competition, or trade regulation law that may be asserted by the FTC, the Antitrust Division, any State Attorney General or any other Governmental Authority with respect to the Merger (including if so requested by the Company by agreeing to dispose of, hold separate or accept limitations on the activities of, any businesses or assets) so as to enable the Closing to occur as soon as reasonably possible, but in any event in sufficient time to ensure that the Effective Time occurs before the Termination Date (as defined below). Each party shall (i) promptly notify the other party of any written communication to that party or its affiliates from any Governmental Authority in respect of any filing, investigation or inquiry concerning this Agreement or the Merger and, subject to applicable Law, permit the other party to review in advance any proposed written communication to any of the foregoing; (ii) not agree to participate, or to permit its affiliates to participate, in any substantive meeting or discussion with any Governmental Authority in respect of any filing, investigation or inquiry concerning this Agreement or the Merger unless it consults with the other party in advance and, to the extent permitted by such Governmental Authority, gives the other party the opportunity to attend and participate in such meeting; and (iii) furnish the other party with copies of all correspondence, filings, and communications (and memoranda setting forth the substance thereof) between them and their affiliates and their respective representatives on the one hand, and any Governmental Authority or members of their respective staffs on the other hand, with respect to this Agreement and the Merger.

(d) The Company and Parent will cooperate and use their respective reasonable best efforts to obtain as promptly as practicable all consents, approvals and waivers required by third persons so that all Company Permits and contracts of the Company and each Company Subsidiary will remain in full force and effect after the Effective Time.

(e) Notwithstanding anything to the contrary in this Agreement, (x) neither Parent nor any of its subsidiaries shall be required in connection with any Company Regulatory Approval or Parent Insurance Approval, (i) to take any action that would be reasonably expected to adversely affect Parent or its affiliates (other than the Company) following the consummation of the Merger in any material respect,

<PAGE> 30

(ii) if it would reasonably be expected to have a Company Material Adverse Effect, (A) sell, divest, hold separate, or otherwise dispose of any of their or of the Company's or any of the Company Subsidiaries' respective businesses, product lines or assets or (B) conduct their or the Company's or any of the Company Subsidiaries' respective businesses in a specified manner, or (iii) agree to take any of the actions set forth in the immediately preceding clauses (i) or (ii), and (y) no party to this Agreement shall be required (in seeking any Company Regulatory Approvals or Parent Insurance Approvals or otherwise) to waive any of the conditions to the Merger set forth in Article VII as they apply to such party to this Agreement.

Section 6.3 Preparation of Proxy Statement; Meeting of Shareholders.

(a) The Company shall, as soon as reasonably practicable following the date of this Agreement, prepare and file a preliminary form of the Proxy Statement with the SEC and each of the Company and Parent shall use its reasonable best efforts to respond to any comments of the SEC or its staff, and to cause the Proxy Statement to be mailed to the Company's shareholders as promptly as reasonably practicable after responding to all such comments to the satisfaction of the SEC's staff. The Company shall notify Parent promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Proxy Statement or for additional information and shall supply Parent with copies of all correspondence between the Company or any of its representatives, on the one hand, and the SEC or its staff, on the other hand, with respect to the Proxy Statement or the Merger. If at any time prior to the Shareholders Meeting there shall occur any event that is required to be set forth in an amendment or supplement to the Proxy Statement, the Company shall promptly prepare, and, after consultation with Parent, mail to its shareholders such an amendment or supplement. Parent shall cooperate with the Company in the preparation of the Proxy Statement or any amendment or supplement thereto and shall furnish the Company with all information reasonably requested by the Company for inclusion in, or otherwise in respect of, the Proxy Statement. Parent and its counsel shall be given a reasonable opportunity to review and comment upon the Proxy Statement and the related proxy materials and any proposed amendment or supplement to the Proxy Statement prior to its filing with the SEC or dissemination to the Company's shareholders. The Company shall not use any proxy material (including, without limitation, the Proxy Statement or any amendment or supplement thereto) in connection with the Shareholders Meeting without the prior approval of Parent, which approval shall not be unreasonably withheld.

(b) Without limiting the generality of the foregoing, each of the parties shall correct promptly any information provided by it to be used specifically in the Proxy Statement, if and to the extent any such information shall be or have become false or misleading in any material respect and shall take all steps necessary to file with the SEC and have declared effective or cleared by the SEC any amendment or supplement to the Proxy Statement so as to correct the same and to cause the Proxy Statement as so corrected to be disseminated to the Company's shareholders, in each case to the extent required by applicable law or otherwise deemed appropriate by the Company.

(c) The Company shall, in accordance with applicable Law and its articles of organization and by-laws, as promptly as reasonably practicable, duly call, give notice of, convene and hold the Shareholders Meeting for the purpose of obtaining the Company Shareholders' Approval. Subject to the fiduciary duties of the Company's Board of Directors under applicable law, the Company shall include in the Proxy Statement the recommendation of its Board of Directors that the Company Shareholders' approval be given (the "Recommendation"). Notwithstanding anything to the contrary in this Agreement, the Company may (and shall, if so reasonably requested by Parent) adjourn or postpone the Shareholders Meeting to such future date as the Company may reasonably determine, if (x) as of the time for which the Shareholders Meeting is then scheduled (as set forth in the Proxy Statement), there are insufficient shares of Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary

<PAGE> 31

to conduct the business of such Shareholders Meeting or (y) the Company determines in good faith, after consultation with outside counsel, that applicable Law or fiduciary duties of the Board of Directors require the Company to supplement or amend the Proxy Statement in advance of a vote on such approval.

(d) Notwithstanding anything to the contrary in clause (c) of this Section 6.3, at any time before the approval of the Merger and the other transactions contemplated by this Agreement, the Recommendation may be withdrawn or modified if the Board of Directors determines in good faith, after receiving the advice of the Company's outside legal counsel, that the failure to withdraw or modify such recommendation would be inconsistent with the fiduciary obligations of the Company's Board of Directors.

Section 6.4 Public Statements. Unless otherwise required by applicable law or by obligations pursuant to any listing agreement with or rules of the New York Stock Exchange or any other securities exchange (the "Exchange Rules"), the Company will not cause and will use its reasonable best efforts not to permit any public announcement with respect to the subject matter of this Agreement. The initial press release with respect to the Merger and the other transactions contemplated by this Agreement shall require the prior mutual agreement and approval of both Parent and the Company and any subsequent press releases or other public statements (unless required by applicable law or the Exchange Rules) with respect to the Merger or the other transactions contemplated by this Agreement shall be made by or on behalf of the Company, only following prior consultation with and approved by Parent.

Section 6.5 Access to Information; Confidentiality. The Company shall, and shall cause its officers, directors, employees, representatives and agents to, provide to Parent and its officers, directors, employees, consultants, agents, counsel, financial advisors, lenders, advisors and other representatives (collectively "Parent Representatives") with full access during normal business hours with reasonable notice throughout the period from the date of this Agreement through the Effective Time to all of the Company's properties, books, contracts, commitments and records (including, but not limited to, Tax Returns and records) and, during that period, shall furnish promptly to Parent or Parent's Representatives such other information and data concerning the Company's business, properties and personnel as Parent reasonably may request; provided, further, that the foregoing shall not require the Company (a) to permit any inspection or to disclose any information that in the Company's good faith opinion, after consultation with legal counsel and with Parent, would (i) breach in any material respect any confidentiality obligation imposed by contract or under applicable law, or (ii) violate U.S. antitrust laws or (b) to disclose any information of the Company or any of its Subsidiaries that in the Company's good faith determination, after consultation with legal counsel, is deemed to be privileged. Notwithstanding the foregoing, any such investigation or consultation shall be conducted in such a manner as not to interfere unreasonably with the business or operations of the Company or the Company Subsidiaries or otherwise result in any significant interference with the prompt and timely discharge by such employees of their normal duties. Except as required by law, Parent and Subsidiary shall hold, and shall cause the Parent Representatives to hold, in strict confidence all nonpublic documents and confidential information furnished to Parent, Subsidiary and any Parent Representative in connection with the transactions contemplated by this Agreement in accordance with the confidentiality agreement dated as of August 22, 2007 between the Company and Parent (the "Confidentiality Agreement").

Section 6.6 Acquisition Proposals.

(a) The Company shall, and shall cause each Company Subsidiary and its and their respective officers, directors, employees, representatives and agents to, immediately cease any activities, discussions or negotiations with any parties that may be ongoing with respect to an Acquisition Proposal, and require the return or destruction of all confidential information regarding the Company and the Company Subsidiaries provided to any such persons on or prior to the date of this Agreement pursuant to

<PAGE> 32

the terms of any confidentiality agreement or otherwise to the extent provided by any such confidentiality agreement, in each case subject to any restriction or other limitation set forth in any such confidentiality agreement. None of the Company, the Company Subsidiaries nor any of their respective officers, directors, employees, consultants, agents, advisors and other representatives (collectively, the "Company Representatives") shall, directly or indirectly, (i) initiate, participate, solicit or encourage (including by way of providing information), or take any other action designed or reasonably likely to facilitate or encourage, any inquiries, proposals or offers that constitute or may reasonably be expected to lead to, any Acquisition Proposal or engage in any discussions or negotiations with respect thereto or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations, or (ii) approve or recommend, or propose to approve or recommend, an Acquisition Proposal or enter into any merger agreement, letter of intent, agreement in principle, share purchase agreement, asset purchase agreement or share exchange agreement, option agreement or other similar agreement providing for or relating to an Acquisition Proposal or enter into any agreement or agreement in principle requiring the Company to abandon, terminate or fail to consummate the transactions contemplated by this Agreement or breach its obligations hereunder or propose or agree to do any of the foregoing.

(b) Notwithstanding anything to the contrary in Section 6.6(a), until the Company Shareholders' Approval is obtained, if the Company has received from a third party an unsolicited written Acquisition Proposal that the Company's Board of Directors determines in good faith constitutes or reasonably could be expected to lead to a Superior Proposal (as defined below), then the Company may (A) furnish information with respect to the Company and the Company Subsidiaries to the person making the Acquisition Proposal (pursuant to a customary confidentiality agreement not less restrictive of such person, in the aggregate, than the Confidentiality Agreement) and (B) participate in discussions or negotiations with such person regarding the Acquisition Proposal; provided, however, that the Company shall promptly provide to Parent any material non-public information concerning the Company or any Company Subsidiary that is provided to any person pursuant to this Section 6.6(b) and was not previously provided to Parent. (For purposes of this Section 6.6(b), material non-public information will be deemed to have been provided to Parent if it has been posted on the data site utilized by the Company in connection with the transactions contemplated by this Agreement at a time when Parent and its advisers continue to have substantially the same access to such data site as during the negotiation of this Agreement and receive notice of the additions to the data site.)

(c) The Company shall immediately advise Parent orally and in writing of any request for information or of any Acquisition Proposal, the material terms and conditions of such request or Acquisition Proposal; provided, however, that the identity of the person making such request or Acquisition Proposal need not be provided until such time as it provides the Parent Notice (as defined below). The Company will immediately inform Parent of any material change in the details (including amendments or proposed amendments) of any such request or Acquisition Proposal. The Company will promptly provide Parent with any documents received from any such person and promptly provide Parent such information as it may reasonably request.

(d) Notwithstanding anything in this Agreement to the contrary, if, at any time prior to obtaining the Company Shareholders' Approval, the Company receives an Acquisition Proposal which the Company's Board of Directors determines in good faith constitutes a Superior Proposal, the Company's Board of Directors may terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal if the Board of Directors determines in good faith, after consultation with outside counsel, that failure to take such action would be inconsistent with its obligations under applicable Laws; provided, however, that the Company shall not terminate this Agreement pursuant to this Section 6.6(d) and any purported termination pursuant to this Section 6.6(d) shall be void, unless concurrently with such termination the Company pays the Termination Fee (as defined below) payable

<PAGE> 33

pursuant to Section 8.2(b); and provided, further, that the Board of Directors may not terminate this Agreement pursuant to this Section 6.6(d) unless the Company shall have provided prior written notice to Parent (the "Parent Notice"), at least four business days in advance (the "Notice Period"), of its intention to terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal, which notice shall specify the material terms and conditions of the Superior Proposal (including the identity of the party making the Superior Proposal), and shall be accompanied by a copy of a draft of the definitive agreement proposed to be entered into with respect to the Superior Proposal (it being understood that in the event that any material revisions (or revisions that in the aggregate are material) are made to the initial Superior Proposal, the Company shall deliver to Parent within one business day written notice of any such material revisions (including a detailed description thereof) and a new Notice Period shall be deemed to have commenced with respect to such modified Superior Proposal on the date of delivery of such notice to Parent). The Company's Board of Directors shall direct the Company Representatives to negotiate in good faith with Parent and its representatives regarding any proposal Parent may make following any such notice of a Superior Proposal.

(e) Nothing contained in this Agreement shall prohibit the Company's Board of Directors from (i) taking and disclosing to the Company's shareholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act, or (ii) making any other disclosure to the Company's shareholders if, in the case of any disclosure described in this clause (ii), the Company's Board of Directors determines in good faith, after consultation with outside counsel, that such disclosure is required under applicable Law.

(f) For purposes of this Agreement:

"Acquisition Proposal" means any inquiry, proposal, offer or expression of interest by any third party (i) for a merger, consolidation, dissolution, recapitalization or other business combination involving the Company, (ii) for the issuance of 20% or more of the equity securities of the Company as consideration for the assets or securities of another person or (iii) to acquire in any manner, directly or indirectly, 20% or more of the equity securities of the Company or assets (including equity securities of any Company Subsidiary) that represent 20% or more of the assets of the Company, in each case other than the transactions contemplated by or expressly permitted under this Agreement.

"Superior Proposal" means any Acquisition Proposal (but replacing references to "20% or more" in the definition of Acquisition Proposal with "all or substantially all") on terms that the Company's Board of Directors determines in good faith after consultation with the Company's financial advisor to be superior from a financial point of view to the Merger, taking into account all the terms and conditions of such proposal and this Agreement (including any proposal by Parent to amend the terms of this Agreement, and including in each case the risks and probabilities of consummation).

Section 6.7 Expenses and Fees. Whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses.

Section 6.8 Directors' and Officers' Indemnification and Insurance.

(a) Parent agrees that all rights to indemnification and related rights to advancement of expenses on the part of each person who at the Effective Time is a current or former director or officer of the Company, including all such rights existing pursuant to the MBCA, the Company's articles of organization or bylaws or any written agreement between any such person and the Company in effect on the date of this Agreement, shall survive the Merger and shall continue in full force and effect until 180

<PAGE>

days after the expiration of the longest applicable statute of limitation; provided, however, that all rights to indemnification in respect of any claim asserted or made within such period shall continue until the final disposition of such claim. Parent shall cause the Surviving Corporation to comply with its obligations with respect to such rights to indemnification and advancement of expenses.

(b) Parent agrees that, from and after the Effective Time, the Surviving Corporation shall cause to be maintained in effect for not less than six years from the Effective Time the insurance coverage provided under the policies of directors' and officers' liability insurance maintained by the Company at the date of this Agreement; provided, however, that the Surviving Corporation may substitute therefor policies issued by reputable and financially sound carriers that provide at least the same coverage, on terms and conditions which are no less advantageous to such persons but only if such substitution does not result in any gaps or lapses in coverage with respect to matters occurring prior to the Effective Time; and provided, further, that the Surviving Corporation shall not be required to pay an annual premium for such coverage in excess of 250% of the last annual premium paid by the Company prior to the date of this Agreement; and if the Surviving Corporation is unable to obtain the insurance required by this Section 6.8, it shall obtain as much comparable insurance as possible for an annual premium equal to such maximum amount. Parent's obligations under this paragraph may be satisfied by the purchase of a "tail" insurance policy that provides the coverage described above.

(c) If the 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 6.8.

(d) The provisions of this Section 6.8 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties. Parent hereby guarantees the performance of the Surviving Corporation's obligations under this Section 6.8.

Section 6.9 Employee Benefits.

(a) Except as otherwise provided herein, following the Effective Time, Parent shall honor, and cause the Surviving Corporation to honor, each Company Plan and the related funding arrangements of such Company Plan in accordance with its terms. Without limiting the generality of the foregoing, Parent shall honor, and cause the Surviving Corporation to honor, all rights to vacation, personal and sick days accrued by employees of the Company and its subsidiaries under any plans, policies, programs and arrangements of the Company and the Company Subsidiaries through and including the Effective Time. Nothing herein shall prohibit any changes to any Company Plan that are (i) required by law (including any applicable qualification requirements of Section 401(a) of the Code); or (ii) necessary as a technical matter to reflect the transactions contemplated hereby. Nothing herein shall require Parent to continue any particular Company Plan or any particular practice or course of conduct with respect to any Company Plan or prevent the amendment or termination of any plan or benefits (subject to the obligation to provide severance pay and benefits as provided above).

(b) With respect to any employee benefit plans in which any employees of the Company or its subsidiaries first become eligible to participate, on or after the Effective Time, and in which the Company employees did not participate prior to the Effective Time, Parent shall: (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the employees of the Company and the Company Subsidiaries under any such new plans in

<PAGE> 35

which such employees may be eligible to participate after the Effective Time, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous Company Plan; (ii) provide each employee of the Company and the Company Subsidiaries with credit for any co-payments and deductibles paid prior to the Effective Time (to the same extent such credit was given under the analogous Company Plan prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements under any such new plan in which such employees may be eligible to participate after the Effective Time; (iii) recognize all service of such employees for all purposes (including, without limitation, purposes of eligibility to participate and vesting) in any such new plan in which such employees may be eligible to participate after the Effective Time; and (iv) with respect to flexible spending accounts, provide each employee of the Company and the Company Subsidiaries with a credit for any salary reduction contributions made thereto and a debit for any expenses incurred thereunder with respect to the plan year in which the Effective Time occurs; provided, that the foregoing shall not apply to the extent it would result in duplication of benefits.

(c) As soon as reasonably practicable after the date hereof, the Company will cause the governing documents of The Commerce Group, Inc. Employee Stock Ownership Plan (the "Plan") to be amended in accordance with its terms and applicable law so that as of the Closing the portion of the Plan intended to qualify as an employee stock ownership plan within the meaning of Section 4975(e) of the Code (the "ESOP") is terminated, such amendments to be subject to Parent's review and approval. The Company will submit the Plan as so amended to the IRS in order to obtain a favorable determination letter as to the Plan's tax-qualified status following such amendment.

(d) The Company will amend, within the applicable remedial amendment period, any Company Plan in order to comply with the requirements of Section 409A of the Code to the extent applicable and the guidance with respect thereto issued by the IRS and the U.S. Department of the Treasury, provided however, that nothing in this Section 6.9(d) shall require the Company to amend a Company Plan terminated prior the end of such remedial amendment period in accordance with such requirements and guidance.

(e) For the avoidance of doubt, Parent covenants that at all relevant times at and after the Effective Time no RSU Agreement Participant (as defined by the RSU Agreement) shall be a "covered employee" within the meaning of Section 162(m) of the Code, and no distribution in respect to any RSU Agreement shall be deferred by Parent, the Surviving Corporation or otherwise pursuant to Section 4(c) of any RSU Agreement.

Section 6.10 Certain Covenants Regarding Agents.

(a) As promptly as practicable following the date of this Agreement and in compliance with applicable Law, Parent and the Company shall develop a joint plan (the "Agency Plan") for the communication with and retention of the Company's agency force.

(b) Prior to the Effective Time, the Company shall take such action as Parent may reasonably request to terminate, subject to the occurrence of the Effective Time, the right of any person to obtain from the Company an Agent Option after the Effective Time.

Section 6.12 Commitment. Parent shall provide the Company written notice within 48 hours of such time as the Commitment is withdrawn or terminated, or amended or supplemented in any respect, or if any event occurs which, with or without notice, lapse of time or both, would constitute a default or breach on the part of Parent or Subsidiary under any term or condition of the Commitment, or that reasonably could be expected to result in any of the conditions precedent to the obligations of the lender and its affiliates under the Commitment not being satisfied.

<PAGE> 39

(d) by Parent:

(i) if the Company (i) materially breaches its obligations under Section 6.6, or the Board of Directors of the Company shall resolve to do so, or (ii) materially breaches its obligations under Section 6.3 and, in either case, such breach is not cured by the earlier of (x) five business days after the Company's receipt of written notice asserting such breach from Parent or (y) two business days prior to the Termination Date;

Section 8.2 Effect of Termination.

(a) In the event of termination of this Agreement by either Parent or the Company pursuant to the provisions of Section 8.1, this Agreement forthwith shall become void and there shall be no liability or further obligation under or in respect of this Agreement on the part of the Company, Parent, Subsidiary or their respective officers or directors, other than in respect of Section 6.7, this Section 8.2 and Article IX, all of which shall survive and except that nothing herein shall relieve any party from liability or damages resulting from (i) knowing, intentional misrepresentation or fraud or (ii) a willful material breach of any covenant or agreement set forth in this Agreement.

(b) The Company agrees that a fee (a "Termination Fee") shall be payable under certain circumstances following a termination of this Agreement, as follows:

(i) if this Agreement is terminated by the Company pursuant to Section 8.1(c)(i) or by Parent pursuant to Section 8.1(d)(i) or Section 8.1(d)(ii), the Termination Fee shall be payable immediately upon such termination, and

(ii) if (A) this Agreement is terminated by the Company or Parent pursuant to Section 8.1(b)(iii) or by Parent pursuant to Section 8.1(d)(iii), (B) after the date of this Agreement and before the termination described in clause (A), an Acquisition Proposal by a third party has been publicly disclosed or announced and not withdrawn (x) in the case of a termination pursuant to Section 8.1(b)(iii), at least 10 days before the Shareholders Meeting or (y) in the case of a termination pursuant to Section 8.1(d)(iii), before the applicable breach by the Company, and (C) in either of the cases referred to in this clause (ii), within one year after the termination the Company shall consummate a transaction or enter into a definitive agreement or agreement in principle for a transaction with any third party that involves the consummation of a transaction described in the definition of Acquisition Proposal (but replacing references to "20% or more" with "50% or more") (an "Alternative Transaction"), then in either of the cases referred to in this clause (ii), upon consummation of the Alternative Transaction, the Company shall pay the Termination Fee.

<PAGE> 40

(c) The amount of the Termination Fee shall be $68.0 million, less the amount of any Expense Reimbursement (as defined below) previously paid.

(d) The Termination Fee shall be paid as directed by Parent by wire transfer of immediately available funds promptly, but in no event later than two business days, after it first becomes due.

(e) If this Agreement is terminated pursuant to Section 8.1(b)(iii) in a situation described in clause (B) of Section 8.2(b)(ii), but the Termination Fee (or any portion thereof) has not been paid and is not payable because the circumstances referred to in clause (C) of Section 8.2(b)(ii) shall not have occurred, the Company shall pay at the direction of Parent as promptly as practicable (but in any event within two business days after receipt of Parent's request therefor), an amount on account of the expenses incurred by Parent and its affiliates in connection with this Agreement and the transactions contemplated hereby in the amount of $7.5 million (the "Expense Reimbursement").

(f) The Company acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated in this Agreement, and that, without these agreements, Parent would not enter into this Agreement. Accordingly, if the Company fails to pay the amount due pursuant to this Section 8.2 when it is required to be paid, and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company, the Company shall pay to Parent its costs and expenses (including attorneys' fees) in connection with such suit, including any costs of collection, together with interest on the amount of the amount determined to be owed at the rate of 8.0% per annum from the date such fee was required to be paid.

No provision of this Agreement shall be interpreted or construed against any party solely because that party or its legal representative drafted the provision.

Section 9.11 Enforcement. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms. It is accordingly agreed that the parties shall be entitled to specific performance of the terms hereof, this being in addition to any other remedy to which they are entitled at law or in equity.

Section 9.12 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 Company Subsidiary to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause such Company Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Corporation to cause such Company Subsidiary to take such action.

Section 9.13 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party. Signatures delivered by facsimile or by electronic data file shall have the same effect as originals.

Section 9.14 Entire Agreement. This Agreement (including the documents and instruments referred to herein) and the Confidentiality Agreement constitute the entire agreement among the parties hereto with respect to the subject matter hereof, and supersede all prior agreements and understandings, both oral and written, among the parties with respect to the subject matter of this Agreement.
