The parties will make all other filings or recordings as may be required under the PBCL, and the Merger will become effective when the Articles of Merger are filed in the office of the Pennsylvania Department of State, or at such later date or time as NEWCO and Eastern agree and specify in the Articles of Merger (the time the Merger becomes effective being the “Effective Time”).

1.3 Effects of Merger. At and after the Effective Time, the Merger shall have the effects set forth in this Agreement, the Articles of Merger and the PBCL, including but not limited to Section 1929 of the PBCL.

At the Effective Time, as a result of the Merger without any action on part of the holder of any capital stock of ProAssurance, NEWCO or Eastern, each of the shares of NEWCO common stock, no par value (“NEWCO Common Stock”), issued and outstanding prior to the Effective Time shall convert into one share of common stock of Eastern, no par value (the “Eastern Common Stock”). It is the intention of the parties that, immediately after the Effective Time, ProAssurance shall own all of the issued and outstanding shares of Eastern Common Stock as the surviving corporation of the Merger.

1.5 Conversion of Eastern Capital Stock. Subject to the terms and conditions of this Agreement, the following exchange shall occur at the Effective Time:

(b) Each holder of Eastern Common Stock shall cease to have any rights as shareholders of Eastern at and after the Effective Time.

(c) Each share of Eastern Common Stock that is owned by Eastern or any Eastern Subsidiary shall automatically be cancelled and retired and shall cease to exist, and no Stock Consideration shall be delivered in exchange therefore.

(b) Prior to the Effective Time, the Board of Directors of Eastern (or if appropriate, any committee thereof) shall adopt appropriate resolutions and take all other actions necessary and appropriate to provide that, immediately prior to the Effective Time, in accordance with the terms of the applicable Eastern Stock Plans, by virtue of the Merger and without any action on the part of the holders of any options or other stock-based awards, each participant in any of the Eastern Stock Plans shall fully and immediately vest in any options or other stock-based awards awarded under such Eastern Stock Plans.

(c) As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each Eastern Stock Option shall be converted into the right to receive an amount in cash equal to the amount by which $24.50 exceeds the exercise price per share of the Eastern Stock Option multiplied by number of shares of Eastern Common Stock previously subject to such Eastern Stock Option without interest (such amounts payable hereunder being referred to as the “Option Consideration”). From and after the Effective Time, any Eastern Stock Option converted pursuant to this Section 1.6 shall be cancelled and no longer exercisable by the former holder thereof, but shall only entitle such holder to the payment of the Option Consideration.

(d) The restrictions on each share of Eastern Restricted Stock shall lapse immediately prior to, and effective upon the occurrence of, the Effective Time, and each share of Eastern Restricted Stock shall be fully vested in each holder thereof at such time, and each such share of Eastern Restricted Stock will be treated at the Effective Time the same as, and have the same rights and be subject to the same conditions hereunder as, each share of Eastern Common Stock, including the cash conversion discussed in Section 1.5 above.

(e) To the extent then in effect, after the Effective Time, all Eastern Stock Plans shall be terminated and no further Eastern Stock Options, shares of Eastern Restricted Stock, or other awards shall be granted under the Eastern Stock Plans.

2.2 Exchange Procedures.

(a) Prior to the Effective Time, ProAssurance shall deposit with the Exchange Agent (the “Exchange Fund”) cash in an amount equal to the sum of the Stock Consideration and Option Consideration (collectively the “Merger Consideration”) and promptly after the Effective Time, but no later than five (5) business days following the Effective Time, Eastern shall deposit with the Exchange Agent a list of the names and addresses of each Person (as defined in Section 9.16(a) of this Agreement) who was a record holder of Eastern Common Stock immediately prior to the Effective Time or who is otherwise entitled to receive the Merger Consideration (collectively the “Merger Consideration Recipients”) and the amount of the cash payment to which each of the Merger Consideration Recipients is entitled under the plan of exchange.

Upon delivery to the Exchange Agent of the duly executed transmittal materials, including any certificates representing shares of Eastern Common Stock (the “Old Certificates”), and such other documents as the Exchange Agent may reasonably require, the holder of such shares of Eastern Common Stock and book entry shares of Eastern Common Stock shall be entitled to receive in exchange therefor the Merger Consideration which such holder has the right to receive in respect of the shares of Eastern Common Stock or book entry shares of Eastern Common Stock surrendered pursuant to the provisions of this Section 2.2 (after taking into account all shares of Eastern Common Stock then held by such holder), and the Old Certificates and book entry shares so surrendered shall forthwith be canceled. Neither ProAssurance nor Eastern, as the surviving corporation, shall be obligated to deliver the Merger Consideration to which any former record holder of Eastern Common Stock is entitled as a result of the Merger until such record holder delivers to the Exchange Agent the executed transmittal materials and, if applicable, his or her certificate or certificates representing the shares of Eastern Common Stock for exchange as provided in this Section 2.2.

(c) Promptly after the Effective Time, but no later than ten (10) business days following the Effective Time, ProAssurance will send or cause to be sent to each person who was a holder of an outstanding Eastern Stock Option or Eastern Restricted Stock that was issued in book entry form only, the payment to which such person is entitled with respect to such Eastern Stock Option or Eastern Restricted Stock under the provisions of Section 1.5(a) and 1.6(c).

(e) At the Effective Time, the stock transfer books of Eastern shall be closed as to holders of Eastern Common Stock immediately prior to the Effective Time, and no transfer of Eastern Common Stock by any such record holder shall thereafter be made or recognized. Until surrendered for exchange in accordance with the provisions of this Section 2.2, each certificate theretofore representing shares of Eastern Common Stock shall from and after the Effective Time represent for all purposes only the right to receive the Merger Consideration provided in this Agreement in exchange therefor.

2.3 Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holder of Eastern Common Stock for six (6) months after the Effective Time shall be delivered to ProAssurance, upon demand, and any holder of Eastern Common Stock who has not theretofore complied with this Agreement shall thereafter look only to ProAssurance for payment of their claim for distributions with respect to the Merger Consideration.

To the extent that such amounts are properly withheld by ProAssurance or the Exchange Agent, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the Merger Consideration Recipient in respect of whom such deduction and withholding were made by ProAssurance or the Exchange Agent.

(b) Except as set forth in Section 3.7(b) of the Eastern Disclosure Schedule, the Eastern SEC Reports (i) were or will be prepared in accordance with the requirements of the Securities Act of 1933, as amended and the rules and regulations thereunder (the “Securities Act”) and the Exchange Act and the rules and regulations thereunder, as the case may be, in all material respects, and (ii) did not at the time they were filed with the SEC, or will not at the time they are filed with the SEC, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. As used in this Section 3.7, the term “file” shall be broadly construed to include any manner in which a document or information is furnished, supplied or otherwise made available to the SEC.

(c) Eastern has established and maintains disclosure controls and procedures (as such term is defined in Section 13(b)(2)(B) and Rule 13a-15(e) under the Exchange Act). Such disclosure controls and procedures: (i) are designed to ensure that material information relating to Eastern and its Subsidiaries is made known to Eastern’s chief executive officer and its chief financial officer by others within those entities, particularly during the periods in which Eastern’s reports and filings under the Exchange Act are being prepared, (ii) have been evaluated for effectiveness as of the end of the most recent annual period reported to the SEC, and (iii) are effective to perform the functions for which they were established. Neither the auditors of Eastern nor the Audit Committee of the Board of Directors of Eastern have been advised of: (x) any significant deficiencies or material weaknesses in the design or operation of the internal controls over financial reporting (as such term is defined in Section 13(b)(2)(B) and Rule 13a-15(f) of the Exchange Act) of Eastern and its Subsidiaries which could adversely affect Eastern’s ability to record, process, summarize and report financial data, and (y) any fraud, whether or not material, that involves management or other employees who have a role in the internal controls over financial reporting of Eastern and its Subsidiaries.

Except (x) as reflected in Eastern’s audited balance sheet at December 31, 2012 (the “2012 Eastern Balance Sheet”), or liabilities described in any notes thereto (or liabilities for which neither accrual nor footnote disclosure is required pursuant to GAAP), or (y) for liabilities incurred in the ordinary course of business since December 31, 2012 consistent with past practice or in connection with this Agreement or the transactions contemplated hereby, neither Eastern nor any Eastern Subsidiary has any material liabilities or obligations of any nature.

Neither Eastern nor any Eastern Subsidiary has waived any statute of limitations in respect of Taxes or agreed to any extension of time with respect to a Tax Return or tax

assessment or deficiency other than extensions that are automatically granted by the taxing authorities upon filing an application therefore. The unpaid Taxes of Eastern and the Eastern Subsidiaries do not exceed the reserve for tax liability set forth on the 2012 Eastern Balance Sheet as adjusted for the passage of time through the Closing Date in accordance with past custom and practice of Eastern in filing its returns. No claim has been made since December 31, 2008 by an authority in a jurisdiction where Eastern or any Eastern Subsidiary does not file Tax Returns that it is or may be subject to taxation by that jurisdiction.

(c) There is no claim, audit, action, suit, proceeding or investigation now pending or, to the Knowledge of Eastern, threatened against or with respect to Eastern or any Eastern Subsidiary in respect of any material Tax. Eastern and each Eastern Subsidiary in connection with amounts paid or owed to any employee, independent contractor, creditor, shareholder or other third party have complied with applicable tax withholding in all material respects. Eastern and each Eastern Subsidiary have reported such withheld amounts to the appropriate taxing authority and to each such employee, independent contractor, creditor, shareholder or other third party as required by applicable law.

(d) There are no Tax Liens upon any property or assets of Eastern or its Subsidiaries except Liens for current Taxes not yet due. Neither Eastern nor any Eastern Subsidiary has been required to include in income any adjustment pursuant to Section 481 of the Internal Revenue Code of 1986, as amended (the “Code”) by reason of a voluntary change in accounting method initiated by Eastern or any Eastern Subsidiary, and the IRS has not initiated or proposed any such adjustment or change in accounting method. Except as set forth in the Eastern GAAP Financial Statements, neither Eastern nor any Eastern Subsidiary has entered into a transaction which is being accounted for as an installment obligation under Section 453 of the Code. Neither Eastern nor any Eastern Subsidiary is a party to or bound by any tax indemnity, tax sharing or tax allocation agreement (other than such agreements as exist by and among themselves). Neither Eastern nor any Eastern Subsidiary has ever been a member of an affiliated group of corporations within the meaning of Section 1504 of the Code other than as a common parent corporation. Neither Eastern nor any Eastern Subsidiary is liable for the Taxes of any person under Section 1.1502-6 of the Treasury Regulations (or any similar provision of state, local or foreign Tax law) or by contract, as a successor or otherwise. During the five (5) year period ending on the date hereof, neither Eastern nor any Eastern Subsidiary was a distributing corporation or a controlled corporation in a transaction intended to be governed by Section 355 of the Code. Neither Eastern nor any Eastern Subsidiary is a party to any joint venture, partnership or other arrangement or contract that could be treated as a partnership for federal income tax purposes.

(e) Except as set forth in Section 3.13(e) of the Eastern Disclosure Schedule, any amount that is reasonably likely to be received (whether in cash or property or the vesting of property) as a result of any of the transactions contemplated by this Agreement by any employee, officer or director of Eastern or any of its affiliates who is a “Disqualified Individual” (as such term is defined in proposed Treasury Regulation Section 1.280G(1) under any employment, severance or termination agreement, other compensation arrangement or Eastern Employee Plan (as defined in Section 3.14 of this Agreement) currently in effect will not be characterized as an “excess parachute payment” (as such term is defined in Section 280G(b)(1) of the Code).

(f) There has been no disallowance of a deduction under Section 162(m) of the Code for employee remuneration of any amount paid or payable by Eastern or any Eastern Subsidiary under any contract, plan, program, arrangement or understanding.

(g) There is no dispute or claim concerning any tax liability of Eastern or any Eastern Subsidiary except as disclosed in Section 3.13(g) of the Eastern Disclosure Schedule. Section 3.13(g) of the Eastern Disclosure Schedule identifies the last Tax Returns that have been audited by the taxing authority with whom they were filed, and indicates those Tax Returns that currently are the subject of an audit procedure or that Eastern or any Eastern Subsidiary has received notice will be subject to an audit procedure. Eastern has made available to ProAssurance correct and complete copies of all federal income tax returns (including amendments thereto) of, all examination reports of, and statements of deficiencies assessed against or agreed to by, Eastern or any Eastern Subsidiary for any tax year commencing after December 31, 2008.

(h) Except as set forth in Section 3.13(h) of the Eastern Disclosure Schedule, Eastern and/or any Eastern Subsidiary will not have any taxable income or gain as a result of prior inter-company transactions that will be taken into account as a result of the changes in ownership contemplated herein.

3.14 Employee Plans; Labor Matters.

(a) Section 3.14(a) of the Eastern Disclosure Schedule sets forth a true and complete list of all of the Employee Plans (as defined in Section 9.16(a) of this Agreement) for employees of Eastern and any Eastern Subsidiary (“Eastern Employee Plans”). Those Eastern Employee Plans which cover only employees of Eastern or a Eastern Subsidiary are separately identified. Those Eastern Employee Plans which are non-qualified deferred compensation plans for purposes of Section 409A of the Code are separately identified and are in compliance with the requirements of Section 409A and the regulations promulgated thereunder. Except with respect to the Eastern Employee Plans, neither Eastern nor any Eastern Subsidiary sponsors, maintains or contributes to, or has any ongoing obligation or liability whatsoever with respect to: (i) any employee benefit plan as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or (ii) any other program, plan, trust agreement or arrangement for any bonus, severance, hospitalization, vacation, sick pay, incentive, deferred compensation, pension, profit sharing, post-employment, retirement, payroll savings, stock option, stock purchase, group insurance, self-insurance, death benefit, fringe benefit, welfare or any other employee benefit plan or fringe benefit arrangement of any nature whatsoever

including those for the benefit of former employees. Neither Eastern nor any Eastern Subsidiary has any agreement, arrangement, commitment, or understanding, whether legally binding or not, to create any additional Eastern Employee Plan or to continue, modify, change, or terminate, in any material respect, any Eastern Employee Plan except as may be required by the Code or ERISA. ProAssurance may modify, amend and/or terminate any Eastern Employee Plan after the Effective Time, subject to applicable law and the terms of such Eastern Employee Plan.

(b) Eastern has heretofore delivered or made available to ProAssurance true and complete copies of each Eastern Employee Plan and certain related documents, including: (i) the plan document and the related trust agreement or annuity contract for such Eastern Employee Plan; (ii) the summary plan description and material employee communication document for such Eastern Employee Plan; (iii) the actuarial report for such Eastern Employee Plan (if applicable) for each of the last two years; (iv) all determination letters from the IRS (if applicable) for such Eastern Employee Plan; (v) all insurance policies relating thereto and any written materials used by Eastern to describe employee benefits to employees of Eastern and the Eastern Subsidiaries; (vi) the most recent annual return on Form 5500 (including all schedules thereto along with the accompanying auditor’s opinion, if applicable) and tax return (Form 990) for such Eastern Employee Plan; (vii) the most current actuarial, valuation, and trustee’s reports (as applicable) for such Eastern Employee Plan; and (viii) all material communications with any governmental entity or agency (including the Department of Labor, the Internal Revenue Service, the Pension Benefit Guaranty Corporation, and the Securities and Exchange Commission) with respect to such Eastern Employee Plan. Each such actuarial or valuation report correctly shows the value of the assets of such Eastern Employee Plan as of the date thereof, the total accrued and vested liabilities, all contributions by Eastern and the Eastern Subsidiaries, and the assumptions on which the calculations are based.

(c) Except as set forth in Section 3.14(c) of the Eastern Disclosure Schedule, each of the Eastern Employee Plans has been operated and administered in all material respects in compliance with applicable laws, including, but not limited to, ERISA and the Code. To the Knowledge of Eastern, there has not been any material violation of the reporting and disclosure provisions of the Code and ERISA. There has not been any termination or partial termination (including any termination or partial termination attributable to the transactions contemplated by this Agreement) of such plans. Neither Eastern nor any Eastern Subsidiary nor any of their respective ERISA affiliates, nor any predecessor thereof, contributes to, or has within the past six years contributed to, any multiemployer plans, as defined in Section 3(37) of ERISA, or any multiple employer welfare arrangements, as defined in Section 3(40) of ERISA. Neither Eastern nor any Eastern Subsidiary nor any of their respective ERISA affiliates, nor any predecessor thereof, sponsors, participates in, or contributes to, or has at any time in the past sponsored, participated in, or contributed to (i) any plan which is subject to the funding standards or requirements described in Section 412 of the Code, or (ii) any plan which is subject to any of the requirements, obligations, and liabilities imposed by Title IV of ERISA.

(d) Each Eastern Employee Plan which is intended to be qualified under Section 401(a) of the Code is so qualified and has received a favorable determination letter or has pending or has time remaining in which to file, an application for such determination from the IRS, and Eastern is not aware of any reason why any such determination letter should be revoked or not be reissued, and any related trust is exempt from taxation under Section 501(a) of

the Code. Except as set forth in Section 3.14(d) of the Eastern Disclosure Schedule, each Eastern Employee Plan has been maintained in material compliance with its terms and with the requirements prescribed by any and all applicable laws and regulations, including but not limited to ERISA and the Code. No prohibited transaction within the meaning of Section 406 of ERISA or Section 4975 of the Code, or breach of fiduciary duty under Title I of ERISA has occurred with respect to any Eastern Employee Plan or with respect to Eastern or any Eastern Subsidiary. No events have occurred with respect to any Eastern Employee Plan that could result in payment or assessment by or against Eastern or any Eastern Subsidiaries of any material excise taxes under Sections 4972, 4975, 4976, 4977, 4979, 4980B, 4980D, 4980E or 5000 of the Code.

(e) There has been no amendment to, written interpretation or announcement (whether or not written) by Eastern or any Eastern Subsidiary or of their affiliates relating to, or change in employee participation or coverage under, any Eastern Employee Plan which would increase materially the expense of maintaining Eastern Employee Plans above the level of the expense incurred in respect thereof for the fiscal year ended December 31, 2012. To the Knowledge of Eastern, no event has occurred or circumstances exist that could result in a material increase in the premium costs of Eastern Employee Plans that are insured, or a material increase in benefit costs of the Eastern Employee Plans that are self-insured.

(f) Except as set forth in Section 3.14(f) of the Eastern Disclosure Schedule, there is no action, suit, investigation, audit or proceeding pending against or involving or, to the Knowledge of Eastern, threatened against or involving any Eastern Employee Plan before any court or arbitrator or any state, federal or local governmental body, agency or official, except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Eastern. Other than claims for benefits submitted by participants or beneficiaries in the ordinary course, no claim against, or legal proceeding involving, any Eastern Employee Plan is pending or threatened.

(g) Except as provided in Sections 1.6 and 6.4(a) of this Agreement and as described in Section 3.14(g) of the Eastern Disclosure Schedule, neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated by this Agreement will (i) result in any material payment (including severance, unemployment compensation, golden parachute or otherwise) becoming due to any director or employee of Eastern or any of its Subsidiaries from Eastern or any of its Subsidiaries under any Eastern Employee Plan or otherwise; (ii) materially increase any benefits otherwise payable under any Eastern Employee Plan; (iii) result in any acceleration of the time of payment or vesting of any such benefits to any material extent (in each case under clauses (i), (ii) or (iii) whether or not such payment or benefit would constitute a parachute payment within the meaning of Section 280G of the Code); (iv) constitute an acceleration of the payment or vesting of deferred compensation in violation of the requirements of Section 409A of the Code; or (v) constitute a prohibited transaction within the meaning of Section 406 of ERISA or Section 4975 of the Code, or breach of fiduciary duty under Title I of ERISA.

(h) Neither Eastern nor any Eastern Subsidiary has any direct or indirect material liability or obligation under any Eastern Employee Plan other than as described in the terms of such Eastern Employee Plans. There are no circumstances arising out of the sponsorship of any Eastern Employee Plan which will result in any direct or indirect material

liability to Eastern or any Eastern Subsidiary, other than liability for contributions, benefit payments, administrative costs and liabilities incurred in accordance with the terms of the Eastern Employee Plans consistent with past practice.

(i) Eastern and each Eastern Subsidiary have made all employer contributions for employee benefits; including deferred compensation obligations, and all such benefits under any Eastern Employee Plan have been paid or provided for in accordance with plan documents, or other arrangements disclosed on Section 3.14(i) of the Eastern Disclosure Schedule. There are no funded benefit obligations under any Eastern Employee Plan for which contributions have not been made or properly accrued, and there are no unfunded benefit obligations that have not been accounted for by reserves, or otherwise properly footnoted in accordance with generally accepted accounting principles on the financial statements of Eastern and each Eastern Subsidiary.

(j) Each Eastern Employee Plan which is an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA that is not qualified under Section 401(a) or 403(a) of the Code is exempt from Parts 2, 3, and 4 of Title I of ERISA as an unfunded plan that is maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees, pursuant to Sections 201(2), 301(a)(3), and 401(a)(1) of ERISA.

(b) Except as set forth in Section 3.23(b) of the Eastern Disclosure Schedule, the Eastern Insurance Subsidiaries have not issued any participating policies or any retrospectively rated policies of insurance.

(c) All ceded reinsurance treaties or agreements, including retrocessional agreements, to which any Eastern Insurance Subsidiary is a party or under which an Eastern Insurance Subsidiary has any existing rights, obligations or liabilities are listed on Section 3.23(c) of the Disclosure Schedule (the “Eastern Ceded Reinsurance Treaties”). Eastern has provided ProAssurance with correct and complete copies of all of such Eastern Ceded Reinsurance Treaties and all such Eastern Ceded Reinsurance Treaties are in full force and effect, and the consummation of the transactions contemplated by this Agreement will not result in the termination of any Eastern Ceded Reinsurance Treaties. The Eastern GAAP Financial Statements accurately reflect all ceded premiums and all amounts recoverable on the Eastern Ceded Reinsurance Treaties in accordance with GAAP as of December 31, 2012 and for the year then ended. To the Knowledge of Eastern there is no material adverse change in the financial condition of its reinsurers that might raise concern regarding their ability to honor their reinsurance commitments, except as set forth in Section 3.23(c) of the Eastern Disclosure Schedule. No party to any of the Eastern Ceded Reinsurance Treaties has given notice to Eastern or any Eastern Insurance Subsidiary that such party intends to terminate or cancel any of the

Eastern Ceded Reinsurance Treaties as a result of or following consummation of the Merger. Since January 1, 2012, no Eastern Ceded Reinsurance Treaty has been terminated and there has not been any change in the retention level under any such Eastern Ceded Reinsurance Treaty that is material to the conduct of the Business.

(d) Section 3.23(d) of the Eastern Disclosure Schedule lists each insurance policy issued by a Eastern Insurance Subsidiary that has been reinsured by a reinsurance treaty issued by a segregated portfolio reinsurance cell (“Eastern Assumed Reinsurance Treaties”) and together with Eastern Ceded Reinsurance Treaties collectively referred to as “Eastern Reinsurance Treaties”) and identifies each such segregated portfolio reinsurance cell in which Eastern or an Eastern Subsidiary holds preferred stock or another equitable security or interest (“Eastern Participation Interest”). Eastern has provided ProAssurance true and correct copies of all such Eastern Assumed Reinsurance Treaties and such Eastern Participation Interests. Except as set forth on Schedule 3.23(d), none of the Eastern Insurance Subsidiaries is a party to a reinsurance agreement or treaty in which the Eastern Insurance Subsidiary has assumed the obligations of any insurance company other than a segregated portfolio reinsurance cell. All Eastern Assumed Reinsurance Treaties are in full force and effect and the consummation of the transactions contemplated by this Agreement will not result in the termination of any Eastern Assumed Reinsurance Treaties. The Eastern Participation Interests have been duly and validly issued and are held by Eastern or a Eastern Subsidiary free and clear of all Liens and restrictions on transfer other than as described on Section 3.23(d) of the Eastern Disclosure Schedule.

(e) Each Eastern Reinsurance Treaty is valid and binding on each party thereto, and none of Eastern, and, to the Knowledge of Eastern, any other party thereto, is in default in any material respect with respect to any such reinsurance agreement or treaty. No Eastern Reinsurance Treaty contains any provision providing that the other party thereto may terminate the same by reason of the transactions contemplated by this Agreement, or contains any other provision which would be altered or otherwise become applicable by reason of such transactions.

(f) Each of the Eastern Insurance Subsidiaries have assets that qualify as admitted assets under the Insurance Laws in an amount at least equal to the sum of all its reserves and liability amounts and its minimum statutory capital and surplus as required by such Insurance Laws. The 2012 Eastern Balance Sheet sets forth all of the reserves for losses and loss reserve expenses, gross of reinsurance, as of the date thereof (the “Eastern Reserves”) in accordance with GAAP. The Eastern Reserves were determined in accordance with GAAP and generally accepted actuarial principles consistently applied, were computed on the basis of methodologies consistent with those used in prior periods, and were fairly stated in accordance with sound actuarial and GAAP accounting principles. The Eastern Reserves are adequate to cover the estimated present value of the ultimate net loss and loss adjustment expenses of the Eastern Insurance Subsidiaries (under generally accepted actuarial standards consistently applied and fairly stated in accordance with sound actuarial principles) under all insurance contracts under which the Eastern Insurance Subsidiaries have or are reasonably expected to have any liability on the date of the 2012 Eastern Balance Sheet. Eastern has provided or made available to ProAssurance copies of all work papers used as the basis for establishing the Eastern Reserves. Except for regular periodic assessments based on developments that are publicly known within the insurance industry no claim or assessment is pending or threatened against

Eastern or any Eastern Insurance Subsidiary which is peculiar or unique to Eastern or such Eastern Insurance Subsidiary by any state insurance guaranty association in connection with such association’s fund relating to insolvent insurers.

(g) Section 3.23(g) of the Eastern Disclosure Schedule lists each actuary, independent or otherwise, that has reviewed, on behalf of Eastern or any Eastern Subsidiary, the reserves for losses and loss adjustment expenses of Eastern or the Eastern Insurance Subsidiaries and their premium rates for liability insurance in each of the years commencing after December 31, 2009 (collectively the “Eastern Actuaries” and separately a “Eastern Actuary”). Section 3.23(g) of the Eastern Disclosure Schedule lists each and every actuarial report, and all attachments, supplements, addenda and modifications thereto prepared for or on behalf of Eastern or any Eastern Subsidiary by the Eastern Actuaries, or delivered by the Eastern Actuaries to Eastern or any Eastern Subsidiary, since December 31, 2009, in which an Eastern Actuary has (i) either expressed an opinion on the adequacy of such reserves for losses and loss adjustment expenses loss reserves or made recommendations as to either the amount of reserves for losses and loss adjustment expenses that should be maintained by Eastern or the Eastern Insurance Subsidiaries, or (ii) expressed an opinion as to the adequacy of such premiums or made a recommendation as to the premiums that should be charged by Eastern or the Eastern Insurance Subsidiaries for liability insurance (collectively, the “Eastern Actuarial Analyses”). To the Knowledge of Eastern the information and data furnished by Eastern or any Eastern Subsidiary to the Eastern Actuaries in connection with the Eastern Actuarial Analyses were accurate in all material respects. Each Eastern Actuarial Analysis was based upon an accurate inventory of policies in force for Eastern and the Eastern Insurance Subsidiaries, as the case may be, at the relevant time of preparation and, to the Knowledge of Eastern, was prepared using generally accepted actuarial principles consistently applied. Eastern has made available to ProAssurance a true and correct copy of each of the Eastern Actuarial Analyses.

(h) Except as set forth in Section 3.23(h) of the Eastern Disclosure Schedule, to the Knowledge of Eastern, there are no facts or circumstances related to the Business that could reasonably be expected to result in Eastern, any Eastern Subsidiary, NEWCO or ProAssurance being liable for any bad faith claim or any market conduct claim with respect to their respective (i) claims-making procedures or (ii) marketing and sale of insurance products.

(i) All benefits claimed by any Person under any insurance contract written or assumed by the Eastern Insurance Subsidiaries have in all material respects been paid (or provision for payment thereof has been made) in accordance with the terms of the contracts under which they arose, such payments were not materially delinquent and were paid (or will be paid) without fines or penalties, except for any such claim for benefits for which Eastern reasonably believes or believed that there is a reasonable basis to contest payment and is taking such action.

(j) Except as disclosed on Section 3.23(j) of the Eastern Disclosure Schedule, no outstanding insurance contract issued, reinsured, or underwritten by the Eastern Insurance Subsidiaries entitles the holder thereof or any other person to receive dividends, distributions, or to share in the income of Eastern or to receive any other benefits based on the revenues or earnings of Eastern or any other Person.

(k) To the extent required by the Insurance Laws of each state in which any Eastern Insurance Subsidiary issues insurance policies, such Eastern Insurance Subsidiary is participating in each risk sharing plan, pool, insurance joint underwriting association or similar arrangement maintained in such state and has paid all assessments and required contributions on or before the date such payments are due. Except for regular periods or special arrangements based on developments that are publicly known with the insurance industry generally or the worker’s compensation liability insurance industry, to the Knowledge of Eastern, no claim or assessment is pending or threatened against Eastern or any Eastern Insurance Subsidiary which is peculiar or unique to Eastern or such Eastern Insurance Subsidiary by any state insurance guaranty association in connection with such association’s fund relating to insolvent insurers.

(l) Each insurance agent or broker, at the time such agent or broker wrote, sold or produced business for the Eastern Insurance Subsidiaries, to the extent required by law, was duly appointed to act as agent and was, to the Knowledge of Eastern, duly licensed as an insurance agent or broker (for the type of business written, sold or produced by such insurance agent or broker) in the particular jurisdiction in which such agent or broker wrote, sold or produced such business. The terms and provisions between an Eastern Insurance Subsidiary and any managing general agent or reinsurance intermediary comply in all material respects with the Insurance Laws.

3.24 Computer Hardware and Software.

(a) The computer hardware and software systems of Eastern and the Eastern Subsidiaries are functioning in all material respects in accordance with their respective functional specifications.

(b) Such computer hardware and software systems are sufficient to meet in all material respects all current management information, financial reporting, underwriting and claims processing needs.

(d) Eastern and the Eastern Subsidiaries are currently obtaining maintenance services sufficient to keep such computer hardware and software systems in good operating condition.

(e) Eastern and the Eastern Subsidiaries, through daily back-ups, are currently storing all computerized data at off-site premises adequate for such purpose.

(a) any written communication from A.M. Best inconsistent with the expectation that the Eastern Insurance Subsidiaries will retain an A.M. Best group rating consistent with their current ratings as disclosed on Section 3.25 of the Eastern Disclosure Schedule; or

(b) any communication from any agent or broker or purchasing group which generates for the Eastern Insurance Subsidiaries, either directly or indirectly, more than $200,000 in annual gross written premium, which communication cancelled, gave notice of cancellation or threatened cancellation of the relationship between it and the Eastern Insurance Subsidiaries or the relationship between it and any of their insureds.

3.26 Related Party Transactions.

For the purposes of this Section 3.26, the term “related person” shall have the meaning set forth in General Instruction 1 of Item 404(a) of Regulation S-K promulgated by the SEC.

ARTICLE 6

ADDITIONAL AGREEMENTS

6.1 Regulatory Matters.

(a) In connection with the solicitation of approval of the Merger by the shareholders of Eastern, Eastern will prepare and file with the SEC, subject to ProAssurance’s review and comment, the preliminary Proxy Statement (which shall comply as to form, in all material respects, with the provisions of Regulation 14A of the Exchange Act and other applicable laws). ProAssurance and Eastern will use all reasonable efforts to respond to the comments of the SEC staff with respect to the Proxy Statement. As soon as practicable after SEC comments, if any, on the preliminary Proxy Statement are resolved, Eastern shall mail or deliver the definitive Proxy Statement to its shareholders in accordance with Regulation 14A under the Exchange Act. The information provided and to be provided by ProAssurance and Eastern for use in the Proxy Statement will not, on such date and on the date on which approval of the Merger by the shareholders of Eastern is obtained, contain any untrue statement of material fact or omit to state any material fact required to be stated in this Agreement or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading. Each of ProAssurance and Eastern agree promptly to correct any such

information provided by it for use in the Proxy Statement which shall have become false or misleading in any material respect and to take all steps necessary to file with the SEC and have 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 corrected to be distributed to the shareholders of Eastern to the extent required by applicable law. To the extent that any disclosure regarding the tax consequences of the Merger is required with respect the Proxy Statement, Eastern will be responsible for any tax opinion in support of the disclosure of the material tax consequences.

(b) To the extent applicable, ProAssurance shall prepare and file with all necessary Governmental Authorities (i) a Notice on Form A and related documents and (ii) the preacquisition notification and report forms and related material on Form E in connection with the Merger.

(c) Pursuant to the HSR Act, ProAssurance and Eastern will promptly prepare and file, or cause to be filed, the HSR Act Report with the Pre-Merger Notification Agencies in respect of the transactions contemplated by this Agreement, which filing shall comply as to form with all requirements applicable thereto and all of the data and information reported therein shall be accurate and complete in all material respects. Each of ProAssurance and Eastern will promptly comply with all requests, if any, of the Pre-Merger Notification Agencies for additional information or documentation in connection with the HSR Act Report forms filed by or on behalf of each of such parties pursuant to the HSR Act, and all such additional information or documentation shall comply as to form with all requirements applicable thereto and shall be accurate and complete in all material respects.

(d) Each party shall provide to the other, (i) promptly after filing thereof, copies of all statements, applications, correspondence or forms filed by such party prior to the Closing Date with the SEC, the Pre-Merger Notification Agencies, the Insurance Regulators and any other Governmental Authority in connection with the transactions contemplated by this Agreement and (ii) promptly after delivery to, or receipt from, such regulatory authorities, all written communications, letters, reports or other documents relating to the transactions contemplated by this Agreement.

(e) The parties hereto shall cooperate with each other and use commercially reasonable efforts to promptly prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and Governmental Authorities which are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Merger), and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such Governmental Authorities. ProAssurance and Eastern shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to ProAssurance or Eastern, as the case may be, and any of their respective Subsidiaries, which appear in any filing made with, or written materials submitted to, any third party or any Governmental Authority in connection with the transactions contemplated by this Agreement. The cooperation and coordination of each party required under this Section 6.1 shall include giving timely public notice of any public hearings regarding the transactions contemplated by this Agreement and having its representatives attend and testify at

such public hearings. In addition, each of the parties hereto shall act reasonably and as promptly as practicable. The parties hereto agree that they will consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated by this Agreement.

(f) ProAssurance and Eastern shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and stockholders/shareholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement or any other statement, filing, notice or application made by or on behalf of ProAssurance, Eastern or any of their respective Subsidiaries to any Governmental Authority in connection with the Merger and the other transactions contemplated by this Agreement.

(g) ProAssurance and Eastern shall promptly advise each other upon receiving any communication from any Governmental Authority whose consent or approval is required for consummation of the transactions contemplated by this Agreement which causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of any such approval will be materially delayed.

6.2 Access to Information.

(a) Upon reasonable notice and subject to applicable laws relating to the exchange or confidentiality of information and to the Confidentiality Agreement dated April 17, 2013 (the “Confidentiality Agreement”), each of ProAssurance and Eastern shall, and shall cause each of their respective Subsidiaries to, afford to the officers, employees, accountants, counsel and other representatives of the other party, reasonable access, during normal business hours during the period prior to the Closing Date, to all its properties, books, contracts, commitments and records and, during such period, each of ProAssurance and Eastern shall, and shall cause their respective Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal securities laws or state insurance laws (other than reports or documents which ProAssurance or Eastern, as the case may be, is not permitted to disclose under applicable law or by agreement); (ii) all other information concerning its business, properties and personnel as such party may reasonably request; and (iii) any other information, confidential or otherwise, relating to the Merger which has not been provided to the other party and is necessary for disclosure in the Proxy Statement, including, but not limited to, the confidential portions of the minutes of Eastern and Eastern Subsidiaries that was not provided pursuant to Section 3.3 of this Agreement. Neither ProAssurance nor Eastern nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of ProAssurance’s or Eastern’s, as the case may be, customers, jeopardize the attorney-client and work product privileges of the entity in possession or control of such information or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) Each of ProAssurance and Eastern agrees to keep confidential, and not divulge to any other party or person (other than employees of, and attorneys, accountants, financial advisors and other representatives for, any said party who agree to be bound by the Confidentiality Agreement), all non-public documents, information, records and financial statements received from the other and, in addition, any and all reports, information and financial information obtained through audits or other reviews conducted pursuant to this Agreement (unless readily ascertainable from public or published information, or trade sources, or already known or subsequently developed by a party independently of any investigation or received from a third party not under an obligation to the other party to keep such information confidential), and to use the same only in connection with the transactions contemplated by this Agreement; and if the transactions contemplated by this Agreement are not consummated for any reason, each party agrees to promptly return to the other party all written materials furnished by the other party, and all copies thereof, in connection with such investigation, and to destroy all documents and records in its possession containing extracts or summaries of any such non-public information.

(c) No investigation by either of the parties or their respective representatives shall affect the representations, warranties, covenants or conditions of the other set forth in this Agreement.

6.3 Eastern Shareholder Approval. Eastern shall call a meeting of its shareholders to be held as soon as reasonably practicable for the purpose of obtaining the requisite Eastern shareholder approval required in connection with this Agreement and the Merger. Eastern will, through its Board of Directors, subject to its fiduciary obligations as determined by its Board of Directors, recommend to its shareholders approval of this Agreement and the Merger.

6.4 Continuing Employees and Employee Plans.

(a) As of the date of Closing, the Eastern Employee Stock Ownership Plan (the “ESOP”) shall terminate by its terms. Prior to the Closing, Eastern shall deliver to ProAssurance a schedule setting forth the number of shares of Eastern Common Stock allocated to each participant’s account, the number of unallocated shares of Eastern Common Stock held by the trustee of the ESOP, the outstanding balance of the ESOP’s outstanding indebtedness, and the method for allocating the unallocated shares to the participant’s account upon termination of the ESOP. As soon as practicable following the execution of this Agreement, Eastern shall file all necessary documents with the IRS to request a favorable determination letter that the ESOP is, upon its termination (and as amended in accordance with this Section 6.4(a)), qualified under the provisions of Sections 401(a), 409, and 4975(e)(7) of the Code. As soon as practicable after the receipt of a final favorable determination letter from the IRS, the account balances in the ESOP, including any surplus in its expense account after full payment of the outstanding ESOP loan and all of the ESOP’s administrative expenses that are payable from the ESOP’s related trust, shall be distributed to participants and beneficiaries in accordance with the provisions of the Code, applicable law and the terms of the ESOP. Prior to Closing, contributions to the ESOP and payments on the ESOP loan shall be made consistent with past practices on the regularly-scheduled contribution or payment dates; provided, however, that Eastern shall make a contribution to, and payment on, the ESOP loan with respect to the period from January 1, 2013 through the date of the Closing (or if the Closing occurs after December 31, 2013, the period from January 1, 2014 through the date of the Closing) but no further contributions shall be made to the ESOP after Closing or with respect to any period after the Closing.

(b) Within a reasonable period (but in no event more than five days) after receipt by the ESOPS’s related trust of the Merger Consideration with respect to the shares held under the ESOP, Eastern, the applicable committee or the trustee (as the case may be under the terms of the applicable ESOP document) shall cause any outstanding ESOP loan balances and accrued interest thereon, to be repaid in full, and subsequently shall allocate any remaining unallocated amounts to the accounts of participants and beneficiaries under the ESOP in accordance with the terms of the ESOP and applicable law.

(c) It is understood that ProAssurance and its Subsidiaries are “at-will” employers. Nothing in this Section 6.4 shall be interpreted as preventing ProAssurance from terminating the employment of any individual or from amending, modifying or terminating any ProAssurance Employee Plans, or Eastern Employee Plan, or any benefits under any ProAssurance Employee Plans or any Eastern Employee Plans, or any other contracts, arrangements, commitments or understandings, in accordance with their terms and applicable law, subject to the commitments provided in Section 6.4(d), (e), and (f) of this Agreement. ProAssurance has no plans to consolidate any functions or operations that would result in a loss of jobs within the first twelve (12) months after the Closing Date for the employees of Eastern who are employed by Eastern as of the Closing Date and who continue as employees of Eastern after the Closing Date (the “Continuing Employees”). Furthermore, ProAssurance agrees that no Continuing Employee shall be terminated prior to the twenty-fourth (24^th) month after the Closing Date without first consulting Eastern’s president. Any Continuing Employee who is involuntarily terminated without cause within the first eighteen (18) months after the Closing Date shall receive severance equal to six (6) months of such terminated employee’s then current base compensation.

(d) In the event of any termination or consolidation of any Eastern health plan with any ProAssurance health plan, ProAssurance shall make available to Continuing Employees and their dependents employer-provided health coverage on substantially the same basis as it provides such coverage to ProAssurance employees. Except in the case of a Continuing Employee and/or a dependent of a Continuing Employee (i) who affirmatively terminates coverage under a Eastern health plan prior to the time that such Continuing Employee and/or dependent becomes eligible to participate in the corresponding ProAssurance health plan, or (ii) who has an event which, under the terms of the Eastern health plan, results in a loss of coverage (which may include a sale or other disposition of a Eastern Subsidiary or substantially all of the business operations thereof), no coverage of any of the Continuing Employees or their dependents shall terminate under any of the Eastern health plans prior to the time such Continuing Employees and their dependents become eligible to participate in the health plans, programs and benefits common to similarly situated employees of ProAssurance and their dependents. In the event of a termination or consolidation of any Eastern health plan, terminated Eastern employees (whether terminated before or after the Effective Time) and qualified beneficiaries will have the right to continued coverage under group health plans of ProAssurance in accordance with Code Section 4980B(f), consistent with the provisions below. In the event of any termination of any Eastern health plan, or consolidation of any Eastern health plan with any ProAssurance health plan, any coverage limitation under the ProAssurance health plan due to

any pre-existing condition shall be waived by the ProAssurance health plan to the degree that such condition was covered by the Eastern health plan and such condition would otherwise have been covered by the ProAssurance health plan in the absence of such coverage limitation. All Eastern Employees who cease participating in a Eastern health plan and become participants in a comparable ProAssurance health plan during any plan year shall receive credit toward the applicable deductible under the ProAssurance health plan for any amounts paid by the employee under Eastern’s health plan during the applicable plan year, upon substantiation, in a form satisfactory to ProAssurance that such payments have been made.

(e) ProAssurance shall, with respect to each Continuing Employee, as of Closing (i) continue to maintain the current Employee Plans, for such Continuing Employees in accordance with their terms after the Closing Date for the transition period described in Code Section 410(b)(6)(C) including health insurance coverage with deductibles and other terms, in the aggregate, no less favorable than those being provided prior to the Closing Date except that the ESOP shall be terminated as of the Effective Time and the benefits under the qualified and nonqualified defined benefit plans shall continue to be frozen as provided as of the date of this Agreement until terminated by ProAssurance; and (ii) honor accrued paid time off (including vacation, sick leave and other paid time off) benefits on the date of this Agreement for each Continuing Employee. On or before March 1, 2014, ProAssurance shall pay or cause Eastern to pay to the Eastern employees entitled thereto such bonuses or other awards to which such employees are entitled under the terms of Eastern’s Management Annual Incentive Plan based on the performance factors established by Eastern’s Compensation/Human Resources Committee for calendar year 2013 and excluding any expenses, including retention payments made to Eastern employees, incurred by Eastern in connection with the transactions contemplated by this Agreement.

(f) After the expiration of the transition period described in Code Section 410(b)(6)(C), Continuing Employees who remain employed by ProAssurance shall be given credit for all purposes (including vacation accrual) under the employee benefit plans, policies, programs and arrangements maintained from time to time by ProAssurance, for such employees’ service with Eastern (including any deductibles, or co-insurance limits under any employee welfare benefit plan, as defined in Section 3(1) of ERISA, but not for benefit accruals under any ProAssurance retirement plan), to the same extent and for the same purposes that such service was taken into account under a corresponding Eastern Employee Plan as of the Closing Date and identified in Section 3.14(a) of the Eastern Disclosure Schedule; provided, however, that no such service shall be credited to the extent that it would result in a duplication of benefits.

(g) [Intentionally Omitted].

(h) ProAssurance and Eastern acknowledge and agree that nothing contained herein, whether express or implied, (i) shall be treated as an amendment to or other modification of any Employee Plan or any other employee benefit plan, program or arrangement or, (ii) subject to the provisions of Section 6.4(a) above, shall limit the right of ProAssurance to amend, terminate, or otherwise modify (or cause to be amended, terminated or otherwise modified) any Employee Plan, program or arrangement following the expiration of the transition period described in Code Section 410(b)(6)(C).

(i) The persons named in Section 6.4(i) of the Eastern Disclosure Schedule (the “Eastern Executives”) have entered into Employment Agreements with Eastern that provide for the payment of certain benefits on involuntary termination (or, in certain cases, “good reason” termination) after a change of control of Eastern as described in Section 6.4(i) of the Eastern Disclosure Schedule (the “Eastern Executive Agreements”). ProAssurance has offered and/or entered into a retention and severance agreement with each of the Eastern Executives (the “Retention and Severance Compensation Agreement”) that includes the terms set forth on Exhibit 6.4(i). The execution of the Retention and Severance Compensation Agreement by an Eastern Executive will terminate the applicable Eastern Executive Agreement as of the Effective Time. If an Eastern Executive does not sign a Retention and Severance Compensation Agreement, ProAssurance shall cause Eastern or the applicable Eastern Subsidiary to honor its obligations to pay any Eastern Executive the change of control or severance benefit provided in the Eastern Executive Agreements; provided that Eastern shall use commercially reasonable efforts to cause each Eastern Executive who does not sign a Retention and Severance Compensation Agreement to execute a resignation and release of claims against Eastern and ProAssurance with respect to their severance benefits.

(j) Section 6.4(j) of the Eastern Disclosure Schedule sets forth a list of all Persons (other than the Eastern Executives) who are entitled to change of control or severance benefits under the terms of their respective agreements with Eastern or an Eastern Subsidiary, which list sets forth the name of each Person entitled to such benefits and the amounts payable to each of such Persons on a change of control and/or separation from employment. ProAssurance shall cause Eastern or the applicable Eastern Subsidiary to honor its obligations to pay to any Person listed in Section 6.4(j) of the Eastern Disclosure Schedule the change of control and severance benefits described in Schedule 6.4(j) of the Eastern Disclosure Schedule; provided that ProAssurance shall require in connection with such payments that each officer or employee receiving a payment shall execute a resignation and release of claims against Eastern and ProAssurance with respect to their severance benefits.

6.5 Directors’ and Officers’ Indemnification and Insurance.

(a) ProAssurance shall cause the individuals serving as officers and directors of Eastern and the Eastern Subsidiaries, immediately prior to the Effective Time to be covered for a period of six (6) years from the Effective Time (or the period of the applicable statute of limitations, if longer) by the directors’ and officers’ liability insurance policy maintained by Eastern or the Eastern Subsidiary (provided that ProAssurance may substitute therefore policies of the same or substantially similar coverage and amounts containing terms and conditions which are not less advantageous in any material respect than such policy) with respect to acts or omissions occurring prior to the Effective Time which were committed by such officers and directors in their capacity as such; provided, however, that in no event shall ProAssurance be required to expend more than 400% of the current amount expended by Eastern or the Eastern Subsidiary (the “Insurance Premium Amount”) to maintain or procure insurance coverage pursuant hereto; and provided further, that if ProAssurance is unable to maintain or obtain the insurance called for by this Section 6.5, ProAssurance shall use its best efforts to obtain as much comparable insurance as available for an amount equal to 400% of the Insurance Premium Amount.

(b) In addition to the indemnification under Section 6.5(a), ProAssurance and Eastern shall jointly and severally indemnify, defend and hold harmless each person who is now, or who has been at any time before the date hereof or who becomes before the Effective Time, an officer, director or employee of Eastern or an Eastern Subsidiary (the “Indemnified Parties”) against all losses, claims, damages, costs, expenses (including attorney’s fees), liabilities or judgments or amounts that are paid in settlement of or in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, or administrative (each a “Claim”), in which an Indemnified Party is, or is threatened to be made, a party or witness in whole or in part on or arising in whole or in part out of the fact that such person is or was a director, officer or employee of Eastern or an Eastern Subsidiary if such Claim pertains to any matter of fact arising, existing or occurring at or before the Effective Time (including, without limitation, the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time (the “Indemnified Liabilities”), to the fullest extent Eastern is permitted under applicable law, and in accordance with the terms of indemnification provisions under, Eastern’s Articles of Incorporation and Bylaws as of the date of this Agreement. ProAssurance shall pay expenses in advance of the final disposition of any such action or proceeding to each Indemnified Party to the full extent provided in Eastern’s Articles of Incorporation as of the date of this Agreement. The Indemnified Parties may retain counsel reasonably satisfactory to them after consultation with ProAssurance; provided, however, that (i) ProAssurance shall have the right to assume the defense thereof and upon such assumption ProAssurance shall not be liable to any Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if ProAssurance elects not to assume such defense the Indemnified Party may retain counsel reasonably satisfactory to him after consultation with ProAssurance, and ProAssurance shall pay the reasonable fees and expenses of such counsel for the Indemnified Party, (ii) ProAssurance shall be obligated pursuant to this paragraph to pay for only one firm of counsel for all Indemnified Parties except to the extent representation by a single firm or attorney is, in the absence of an informed consent by the Indemnified Party, prohibited by ethical rules relating to lawyers’ conflicts of interest, (iii) ProAssurance shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld), (iv) ProAssurance shall have no obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall ultimately determine, and such determination shall have become final and nonappealable, that indemnification of such Indemnified Party in the manner contemplated by this Agreement is prohibited by applicable law, and (v) ProAssurance shall have no obligation hereunder to any Indemnified Party for which and to the extent payment is actually and unqualifiedly made to such Indemnified Party under any insurance policy, any other agreement for indemnification or otherwise. Any Indemnified Party wishing to claim Indemnification under this Section 6.5, upon learning of any such claim, action, suit, proceeding or investigation, shall notify ProAssurance thereof, provided that the failure to so notify shall not affect the obligations of ProAssurance under this Section 6.5, except to the extent such failure to notify materially prejudices ProAssurance. ProAssurance’s obligations under this Section 6.5 continue in full force and effect for a period of six (6) years from the Effective Time (or the period of the applicable statute of limitations, if longer); 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.

(c) In the event that Eastern as the surviving corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any person (including by dissolution), then, and in each such case, ProAssurance shall cause proper provision to be made so that the successors and assigns of Eastern assume and honor the obligations set forth in this Section 6.5. The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any such present or former director or officer is entitled, whether pursuant to Pennsylvania law, contract or otherwise. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to Eastern or any of the Eastern Subsidiaries or their respective officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 6.5 is not prior to or in substitution for any such claims under any such policies.

6.6 Advice of Changes.

(a) ProAssurance and Eastern shall give prompt notice to the other party as soon as practicable after it has actual Knowledge of (i) the occurrence, or failure to occur, of any event which would or would be likely to cause any party’s representations or warranties contained in this Agreement to be untrue or incorrect in any material respect at any time from the date of this Agreement to the Closing Date, or (ii) any failure on its part or on the part of any of its or its Subsidiaries’ officers, directors, employees, representatives or agents (other than persons or entities who are such employees, representatives or agents only because they are appointed insurance agents of such parties) to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by such party under this Agreement. Each party shall have the right to deliver to the other party a written disclosure schedule as to any matter of which it becomes aware following execution of this Agreement which would constitute a breach of any representation, warranty or covenant of this Agreement by such party, identifying on such disclosure schedule the representation, warranty or covenant which would be so breached, provided that each such disclosure schedule shall be delivered as soon as practicable after such party becomes aware of the matter disclosed therein.

(b) ProAssurance shall update the ProAssurance Disclosure Schedule (the “Closing Date ProAssurance Disclosure Schedule”) to a date that is no earlier than ten (10) business days prior to the Closing Date and no later than seven (7) business days prior to the Closing Date and shall deliver the Closing Date ProAssurance Disclosure Schedule to Eastern not less than three (3) business days prior to the Closing Date. Eastern shall update the Eastern Disclosure Schedule (the “Closing Date Eastern Disclosure Schedule”) to a date that is no earlier than ten (10) business days prior to the Closing Date and no later than seven (7) business days prior to the Closing Date and shall deliver the Closing Date Eastern Disclosure Schedule to ProAssurance not less than three (3) business days prior to the Closing Date. The obligation of ProAssurance to deliver to Eastern the Closing Date ProAssurance Disclosure Schedule as provided above shall be a material obligation for purposes of Section 7.3(b) hereof, and the obligation of Eastern to deliver to ProAssurance the Closing Date Eastern Disclosure Schedule shall be a material obligation for purposes of Section 7.2(a) hereof.

6.7 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of ProAssurance and a Subsidiary of Eastern) or to vest ProAssurance or any of its Subsidiaries with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to this Agreement or the Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by, and at the sole expense of, ProAssurance.

6.8 Negotiations with Other Parties.

(a) So long as this Agreement remains in effect and no notice of termination has been given under this Agreement, Eastern shall not authorize or knowingly permit any of its representatives, directly or indirectly, to initiate, entertain, solicit, encourage, engage in, or participate in, negotiations with any Person or any group of Persons other than the other party to this Agreement or any of its affiliates (a “Potential Acquiror”) concerning any Acquisition Proposal (as defined in Section 6.8(c) of this Agreement) other than as expressly provided in this Agreement.
