similar coverage under a subsequent employer’s group health plan; 
 (iv) Outplacement services that are customary to Executive’s
position; and 
 (v) Payment of the Non-Compete Payment subject to and in accordance with the terms and provisions of Section 8(b)
hereof. 
 (c) Notwithstanding the provisions of Section 5(b) hereof, the Executive shall receive the Severance Benefits described in
this Section 5(c) in lieu of and not in addition to the Severance Benefits described in Section 5(b) hereof if all of the following conditions are satisfied: (A) a Change of Control Transaction is publicly announced during any Renewal

terminate the employment of Executive for any reason other than Cause, Disability or death, or (y) the Executive terminates employment with the Companies for Good Reason; and (C) the Executive executes the Release as required in
Section 5(d) hereof. In such event, the Severance Benefits payable to the Executive pursuant to this Section 5(c) shall be as follows: 

(i) An amount equal to two (2) times the Executive’s Annual Base Salary; 

(ii) An amount equal to two (2) times the Executive’s Average Annual Incentive Award(s) or Bonus(es);

 (iv) Outplacement services that are customary to Executive’s position; and 

(v) Payment of the Non-Compete Payment subject to and in accordance with the terms and provisions of Section 8(b) hereof. 

(d) Executive understands and agrees that the payment of Cash Severance Benefits is subject to and conditioned upon the execution of the
Release substantially in the form attached hereto as Exhibit “A” (the “Release”) within twenty-two days after the Date of Termination without subsequent revocation by Executive within seven (7) days after execution of the
Release. Subject to the foregoing, payment of the Cash Severance Benefits shall be made to Executive in cash or good funds in equal monthly installments during the Restricted Period in 

  
 7 








 
accordance with the normal payroll practices of PROASSURANCE in effect on the Date of Termination. The payment of the Cash Severance Benefits shall commence on the first payroll payment date
following the expiration of thirty (30) days after the Date of Termination; provided that the obligation of the Companies to pay such Cash Severance Benefits to the Executive shall be subject to termination as provided in Section 10 hereof
in the event the Executive violates the covenants under either Section 8(a) or Section 9 hereof. The Companies shall withhold from any amounts payable under this Agreement all federal, state, city or other income and employment taxes that
shall be required. Notwithstanding the foregoing, if the Executive is a “specified employee” within the meaning of Code Section 409A(a)(2)(B)(i), the payment schedule for Severance Benefits shall be modified or adjusted to provide
that no payments shall be made until the expiration of six (6) months following the Date of Termination. In the event that payments are so delayed, a lump sum payment of the accumulated unpaid amounts attributable to the six (6) month
period shall be made to Executive on the first day of the seventh month following the Date of Termination. This six month delay shall not apply to any Severance Benefits which are not subject to the requirements of Section 409A of the Code by
reason of their being separation pay upon an involuntary separation from service and their meeting the requirements and limitations of the regulations under the above referenced Code section. In no event shall the aggregate amount of Severance
Benefits be reduced as a result of such modification or adjustment. For purposes of Code Section 409A, the right to the series of installment payments is to be treated as the right to receive a series of separate payments. 

(e) The outplacement services included in the Severance Benefits shall be provided to the Executive promptly after the execution of the
Release but not later than the end of the calendar year following the year in which the Date of Termination occurred. 
 (f) The Executive
shall be entitled to the following in addition to and not in limitation of the Severance Benefits: (i) accrued and unpaid base salary as of the Date of Termination; (ii) accrued vacation and sick leave, if any, on the Date of Termination
in accordance with the then current policy or plan of the Companies with respect to terminated employees generally; and (iii) vested benefits under the Companies’ employee benefit plans in which the Executive was a participant on Date of
Termination, which vested benefits shall be paid or provided for in accordance with the terms of said employee benefit plans. 
 (g)
Executive shall not be entitled to receive Severance Benefits if employment with the Companies is terminated by reason of death or Disability of Executive (except that Executive shall be entitled to receive any unpaid Retention Payments as provided
in Section 4(c) hereof); or by reason of termination of employment by the Executive without Good Reason; or by reason of termination of employment by the Companies with Cause. 

(h) The Executive shall be under no duty or obligation to seek or accept other employment and shall not be required to mitigate the amount of
the Severance Benefits provided under this Agreement by seeking employment or otherwise; provided, however, that the Executive shall be required to notify the Companies if the Executive becomes covered by a health or dental care program providing
substantially similar coverage, at which time health or dental care continuation coverage provided under this Agreement shall cease. 

  
 8 








 6. Good Reason for Termination. In the event that Executive desires to terminate
employment with the Companies for Good Reason, the Executive must provide the Companies with written notice no later than 45 calendar days after the Executive knows or should have known that Good Reason has occurred; provided that any such notice
shall not be deemed to have been given unless and until a copy of the notice has been delivered to the Chief Executive Officer of PROASSURANCE in accordance with Section 13 hereof. Following the Executive’s notice, the Companies shall have
thirty (30) calendar days to rectify the circumstances causing the Good Reason. If the Companies fail to rectify the event(s) causing the Good Reason within the thirty (30) day period after the Executive’s notice, or if the Chief
Executive Officer of PROASSURANCE delivers to the Executive written notice stating that the circumstances cannot or shall not be rectified, the Executive shall be entitled to assert Good Reason and terminate employment on or before ninety
(90) days after the delivery of the Executive’s notice. Should Executive fail to provide the required notice in a timely manner, Good Reason shall not be deemed to have occurred as a result of that event. The term of this Agreement shall
not be deemed to have expired during the notice period, however, as long as the Executive has provided notice within the term. 
 7.
Cause. If the Executive’s employment relationship with the Companies is terminated by the Companies for Cause, the Executive shall not be eligible for Severance Benefits and for the unvested Retention Benefits and the Non-Compete Payment
and all rights of the Executive and obligations of the Companies under this Agreement shall expire. Any termination of the Executive’s employment by the Companies for Cause shall be communicated by a notice of termination to the Executive. The
notice of termination shall be a written notice indicating the specific termination provision of this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the
Executive’s employment under this provision. In the event the Executive disputes the basis for termination for Cause, Executive may elect to bypass the claims procedure set forth in Section 14 hereof and file for settlement of the dispute
in arbitration as provided in Section 15 hereof; provided that if the arbitrator rules in favor of the Executive, the time for the execution of the Release under Section 5(d) shall be extended twenty-two (22) days after the final
decision by the arbitrator, and in the event the Executive executes the Release during said twenty-two (22) day period and does not revoke the Release within seven (7) days after execution, the Executive shall be paid Severance Benefits
and the Non-Compete Payment as provided in Section 5(d) and Section 8 hereof commencing on the first payroll payment date following the expiration of thirty (30) days after the final decision of the arbitrator (or if earlier, the
December 31 coincident with or immediately following the final decision of the arbitrator); and Executive shall be reimbursed for any COBRA premiums that were paid by Executive in the interim period (but not exceeding the maximum period
specified under Section 5(a) or 5(b) hereof) between the termination of employment for COBRA purposes and the Date of Termination as determined by the arbitrator, with such reimbursement to be made on the first payroll payment date following
the decision of the arbitrator (or if earlier, the December 31 coincident with or immediately following the final decision of the arbitrator).

Insurance Product or Service; or 
 (ii) solicit or induce any employees of the Companies to leave such employment or accept employment

year period commencing on the first payroll payment date following the third anniversary of the Effective Date (unless payment of the Non-Compete Payment has previously commenced under Section 5(a)(ii) hereof); provided that the obligation of
the Companies to pay such Non-Compete Payment to the Executive shall be subject to termination as provided in Section 10 hereof in the event the Executive violates the covenants under either Section 8(a) or Section 9 hereof. The
Companies shall withhold from any amounts payable under this Section 8 all federal, state, city or other income and employment taxes that shall be required. The noncompetition payments shall vest on date hereof and shall be payable to Executive
as herein provided (including payment after termination of employment for any reason other than Cause). If Executive is terminated for Cause all noncompetition payments will be forfeited after the Date of Termination. 

(c) Notwithstanding the provisions of Section 8(b) hereof, the payment of the Non-Compete Payment shall be subject to the following terms
and conditions if the Executive’s employment with the Companies is terminated for any reason during the Initial Term:

Companies terminate the Executive without Cause or if the Executive terminates employment for Good Reason, the Non-Compete Payment shall be made to Executive as part of the Cash Severance Benefits as provided in Section 5(a) hereof; or 

(ii) if the Executive terminates employment with the Companies other than for Good Reason, the payment of the Non-Compete Payment shall be
subject to and conditioned upon the execution of the Release within twenty-two days after the Date of Termination without subsequent revocation by Executive within seven (7) days after execution of the Release. Subject to the foregoing, payment
of the Non-Compete Payment shall be made to Executive in cash or good funds in equal monthly installments during the Restricted Period in accordance with the normal payroll practices of PROASSURANCE in effect on the Date of Termination. The payment
of the Cash Severance Benefits shall commence on the first payroll payment date following the expiration of thirty (30) days after the Date of Termination; provided

the covenants under either Section 8(a) or Section 9 hereof. The Companies shall withhold from any the Non-Compete Payment all federal, state, city or other income and employment taxes that shall be required. Notwithstanding the foregoing,

employment with the Companies is terminated by reason of death or Disability, the Non-Compete Payment shall be made to Executive, or the Executive’s beneficiary, upon termination of employment on the second payroll date immediately following
the Executive’s Date of Termination due to death or Disability, but in no event later than seventy-five (75) days after the end of the year in which the Executive’s Date of Termination occurs. In the event that the Executive and the
Companies dispute whether Executive’s termination of employment is by reason of Disability, the Executive follows the procedure for dispute resolution set forth in Section 14 and/or 15 hereof, and a final decision is rendered finding
termination by reason of Disability, the Non-Compete Payment shall be payable to Executive on the first payroll date after the date of the final decision (or if earlier, the December 31 coincident with or immediately following the date of the
final decision); or

 (b) The Confidential Information is important and is an essential asset
of the Companies. 
 (c) Executive’s knowledge of the Confidential Information could be useful to a competitor of the Companies, and
their affiliates which do or intend to do business in competition with the Companies or their affiliates. 
 In recognition of the facts expressed above,
Executive expressly agrees that Executive shall not use for Executive’s personal benefit, or disclose, communicate or divulge to, or use for the direct or indirect benefit of any person, firm, association or company, any confidential or
competitive material or information of the Companies or their affiliates, or Confidential Information. 
 10. Reasonableness of
Restrictions; Available Remedies. 
 (a) The Companies acknowledge and agree that the duties of Executive may require that Executive
must have and continue to have throughout the period of employment the benefits and use of its goodwill, confidential information and trade secrets to properly carry out Executive’s responsibilities, and that the Companies accordingly promise
to provide Executive with access to new and additional confidential information and trade secrets as they are generated, without regard to the duration of his employment, and to authorize Executive to engage in activities that will create new and
additional confidential information and trade secrets. Executive and the Companies agree that the restrictions contained in Sections 8 and 9 of this Agreement are fair and reasonable in all respects, including the geographic and temporal
restrictions, and that the benefits described in this Agreement, to the extent any separate or special consideration is necessary, are fully sufficient for Executive’s obligations under this Agreement. 

  
 12 








 (b) If the Executive is deemed to have materially breached the non-competition covenants set
forth in Section 8 hereof or the confidentiality covenants set forth in Section 9 hereof, the Companies may, in addition to seeking an injunction or any other remedy they may have, withhold or cancel any remaining payments or benefits due
to the Executive pursuant to Section 5 and Section 8 of this Agreement. The Companies shall give prior or contemporaneous written notice of such withholding or cancellation of payments in accordance with Section 5 hereof. If the
Executive violates any of these covenants, the Companies shall be further entitled to an immediate preliminary and permanent injunctive relief, without bond, in addition to any other remedy which may be available to the Companies. 

11. Policies Regarding Executive Compensation. The Board of Directors of the Corporation has adopted, and may from time to time adopt,
certain policies with regard to executive compensation to conform with applicable laws and regulations, listing requirements, and best practices for public companies. This Agreement shall be subject to such policies, including without limitation the
following policies which became effective December 1, 2010: 
 (a) Holding Period for Stock Awards. The Board of Directors
requires certain executive level employees of the Companies to agree to hold shares of Common Stock issued as stock-based compensation for a minimum period of one year from the date of the payment of the stock-based compensation. Executive hereby
agrees to hold the shares of Common Stock issued to Executive as stock-based compensation incentive compensation, including without limitation, the Retention Payments payable hereunder (other than shares of Common Stock withheld by the companies to
pay income and employment taxes), until the later of either (i) one year from the date of the payment of the stock-based compensation; or (ii) Executive satisfies PROASSURANCE’S minimum holding requirements for senior level
executives. 
 (b) Recoupment of Incentive Compensation. The Board of Directors has adopted a policy which sets forth conditions
under which the Companies will require reimbursement with respect to incentive compensation paid or awarded to an executive level employee when the incentive compensation is based on publicly reported financial statements that are required to be
restated to correct an accounting error due to material noncompliance with the federal securities laws, gross negligence, fraud or misconduct. Executive agrees that incentive compensation (exclusive of the Retention Payments) paid to Executive by
the Companies after the Effective Date shall be subject to the policy of the Board of Directors known as the “ProAssurance Corporation Policy Regarding the Recoupment of Certain Performance-Based Compensation Payments,” as currently in
effect on date of this Agreement or as the same may be amended from time to time (the “Policy”). In addition and notwithstanding the foregoing, it is agreed that the policy shall be expanded and applicable to the Retention Payments, and to
any incentive compensation paid to Executive after the Effective Date that would be affected, in the event the publicly reported financial statements of EASTERN are required to be restated to correct an accounting error due to material noncompliance
with the federal securities laws, gross negligence, fraud or misconduct by EASTERN prior to the Effective Date. 
 12. Successors and
Assigns. This Agreement shall be binding upon and inure to the benefit of the Companies and Executive and their respective devisees, heirs, legal or personal representatives, successors and assigns. Notwithstanding the foregoing, this Agreement
is 

  
 13 








 
personal to the Executive and the rights and obligations hereunder may not be assigned by Executive without the prior written consent of PROASSURANCE. In the event the Executive dies while
receiving Severance Benefits and the Non-Compete Payment (as applicable) under this Agreement, any remaining unpaid Severance Benefits and Non-Compete Payments shall be paid to the designated beneficiary of the Executive (or if none, to the estate
of the Executive) following the payment schedule set forth in Section 5(d) and Section 8 hereof in accordance with the payment instructions from the representative of the estate of the Executive. 

13. Notice. For purposes of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and
shall be deemed to have been duly given when delivered by hand or commercial courier or mailed by United States certified or registered mail, return receipt requested, postage prepaid, addressed to the respective addresses as set forth below or to

14. Claims Procedure. 

(a) The administrator for purposes of this Agreement shall be PROASSURANCE (“Administrator”), whose address is 100 Brookwood Place,
Birmingham, Alabama 35209 Telephone: (205) 877 4400. The “Named Fiduciary” as defined in Section 402(a)(2) of ERISA, also shall be PROASSURANCE. PROASSURANCE shall have the right to designate one or more employees of the
Companies as the Administrator and the Named Fiduciary at any time, and to change the address and telephone number of the same. PROASSURANCE shall give the Executive written notice of any change in the Administrator and Named Fiduciary, or in the
address or telephone number of the same. 
 (b) The Administrator shall make all determinations as to the right of any person to receive
benefits under the Agreement. Any denial by the Administrator of a claim for benefits by the Executive (“the claimant”) shall be stated in writing by the Administrator and delivered or mailed to the claimant within ten (10) days after
receipt of the claim, unless special circumstances require an extension of time for processing the claim. If such an extension is required, written notice of the extension shall be furnished to the claimant prior to the termination of the initial
10-day period. In no event shall such extension exceed a period of ten (10) days from the end of the initial period. Any notice of denial shall set forth the specific 

  
 14 








 
reasons for the denial, specific reference to pertinent provisions of this Agreement upon which the denial is based, a description of any additional material or information necessary for the
claimant to perfect the claim, with an explanation of why such material or information is necessary, and any explanation of claim review procedures, written to the best of the Administrator’s ability in a manner that may be understood without
legal or actuarial counsel. 
 (c) A claimant whose claim for benefits has been wholly or partially denied by the Administrator may request,
within ten (10) days following the receipt of such denial, in a writing addressed to the Administrator, a review of such denial. The claimant shall be entitled to submit such issues or comments in writing or otherwise, as the claimant shall
consider relevant to a determination of the claim, and the claimant may include a request for a hearing in person before the Administrator. Prior to submitting the request, the claimant shall be entitled to review such documents as the Administrator
shall agree are pertinent to the claim. The claimant may, at all stages of review, be represented by counsel, legal or otherwise, of the claimant’s choice. All requests for review shall be promptly resolved. The Administrator’s decision
with respect to any such review shall be set forth in writing and shall be mailed to the claimant not later than ten (10) days following receipt by the Administrator of the claimant’s request unless special circumstances, such as the need
to hold a hearing, require an extension of time for processing, in which case the Administrator’s decision shall be so mailed not later than twenty (20) days after receipt of such request. 

15. Arbitration. The parties to this Agreement agree that final and binding arbitration shall be the sole recourse to settle any claim
or controversy arising out of or relating to a breach or the interpretation of this Agreement, except as either party may be seeking injunctive relief. Either party may file for arbitration. A claimant seeking relief on a claim for benefits,
however, must first follow the procedure in Section 14 hereof and may file for arbitration within sixty (60) days following claimant’s receipt of the Administrator’s written decision on review under Section 14(c) hereof, or
if the Administrator fails to provide any written decision under Section 14 hereof, within sixty (60) days of the date on which such written decision was required to be delivered to the claimant as therein provided. The arbitration shall
be held at a mutually agreeable location, and shall be subject to and in accordance with the arbitration rules then in effect of the American Arbitration Association; provided that if the location cannot be agreed upon the arbitration shall be held
in either Birmingham, Alabama, or Lancaster, Pennsylvania, whichever location is closer to the principal office where the Executive was employed on the Date of Termination. The arbitrator shall consider the claim de novo, and shall not be
required to give deference to the findings of the Administrator. The arbitrator may award any and all remedies allowable by the cause of action subject to the arbitration, but the arbitrator’s sole authority shall be to interpret and apply the
provisions of this Agreement. In reaching its decision the arbitrator shall have no authority to change or modify any provision of this Agreement or other written agreement between the parties. The arbitrator shall have the power to compel the
attendance of witnesses at the hearing. Any court having jurisdiction may enter a judgment based upon such arbitration. All decisions of the arbitrator shall be final and binding on the parties without appeal to any court. Upon execution of this
Agreement, the Executive shall be deemed to have waived any right to commence litigation proceedings regarding this Agreement outside of arbitration or injunctive relief without the express consent of PROASSURANCE. The Companies shall pay all
arbitration fees and the arbitrator’s compensation. If the Executive prevails in the arbitration proceeding, the arbitrator shall require 

  
 15 








 
the Companies to reimburse the Executive for the reasonable fees and expenses of Executive’s personal counsel for his or her professional services rendered to the Executive in connection
with the enforcement of this Agreement. 
 16. Miscellaneous. 

(a) Except insofar as this provision may be contrary to applicable law, no sale, transfer, alienation, assignment, pledge, collateralization
or attachment of any benefits under this Agreement shall be valid or recognized by the Companies. 
 (b) This Agreement is an unfunded
deferred compensation arrangement for a member of a select group of the Companies’ management and any exemptions under ERISA, as applicable to such arrangement, shall be applicable to this Agreement. Nothing in this Agreement shall require or
be deemed to require the Companies or any of them to segregate, earmark or otherwise set aside any funds or other assets to provide for any payments made or required to be made hereunder. 

(c) It is understood, acknowledged and agreed that Executive is and will be an “at will” employee of any one or more of the
Companies. Nothing in this Agreement shall be deemed to create an employment agreement between the Executive and the Companies or any of them providing for Executive’s employment for any fixed duration, nor shall it be deemed to modify or
undercut the Executive’s at will employment status with the Companies. 
 (d) It is understood and agreed by the Companies and
Executive that the terms of this Agreement relating to the payment of Severance Benefits are intended to comply in all respects with the requirements of Code Section 409A. For purposes of determining whether Severance Benefits may be payable to
an Executive in compliance with Code Section 409A, the Executive’s employment will be considered as having been terminated for purposes of this Agreement if the parties reasonably anticipate either (i) that Executive will no longer
perform any services for the Companies or (ii) that the level of bona fide services performed for the Companies (whether as an employee or independent contractor) will permanently decrease to no more than 20% of the average level of bona fide
services performed by Executive over the immediately preceding 36-month period (or the full period of services to the Companies if Executive has been providing services to the Companies for less than 36 months). 

(e) Neither the provisions of this Agreement nor the severance benefits provided hereunder shall reduce any amounts otherwise payable, or in
any way diminish the Executive’s rights as an employee of the Companies, whether existing now or hereafter, under any benefit, incentive, retirement, stock option, stock bonus or stock purchase plan, or other plan or arrangement. 

(f) This Agreement sets forth the entire agreement between the parties with respect to the matters set forth herein and supersedes in their
entirety any prior written or oral agreements or understandings between Executive and the Companies regarding the subject matter of this Agreement. This Agreement may not be modified or amended except by written agreement intended as such and signed
by all parties. 

  
 16 








 (g) The Companies, from time to time, shall provide government agencies with such reports
concerning this Agreement as may be required by law, and shall provide Executive with such disclosure concerning this Agreement as may be required by law or as the Companies may deem appropriate. 

(h) Executive and the Companies respectively acknowledge that each of them has read and understand this Agreement, that they have each had
adequate time to consider this Agreement and discuss it with each of their attorneys and advisors, that each of them understands the consequences of entering into this Agreement, that each of them is knowingly and voluntarily entering into this
Agreement, and that they are each competent to enter into this Agreement. 
 (i) Executive shall not during the Initial Term and the Renewal
Term or any time thereafter, disparage the Companies, its affiliates, and /or respective officers, employees or directors, or engage in conduct resulting in, or likely to result in, damage to the business or professional reputation of the Companies
or their affiliates. The Companies agree that they will not at anytime disparage Executive or engage in conduct resulting in, or likely to result in, the damage to the business or professional reputation of Executive. 

(j) The provisions of this Agreement shall survive the expiration of the terms set forth in Section 2 hereof. If any provision of this
Agreement is determined to be unenforceable, the remainder of this Agreement shall not be affected but each remaining provision shall continue to be valid and effective and shall be modified so that it is enforceable to the fullest extent permitted
by law. Moreover, in the event this Agreement is determined to be unenforceable against any of the Companies, it shall continue to be valid and enforceable against the other Companies. 

(k) This Agreement will be interpreted as a whole according to its fair terms. It will not be construed strictly for or against either party.

 (l) Except to the extent that federal law controls, this Agreement is to be construed according to Delaware law.

 EXHIBIT C 

Calculation of Eastern Consolidated Combined Ratio for Compensation Purposes 

The objective of this ratio is to capture the results of the insurance operations before any transaction related expenses or any allocated overhead expenses
(which does not include either (1) overhead budgeted within Eastern’s projections or (2) any charges for direct expenses of Eastern) of the Eastern Group of Companies, including: 

Eastern Insurance Holdings, Inc. 
 Global Alliance Holdings Ltd.

 Allied Eastern Indemnity Company 
 Eastern Alliance Insurance
Company 
 Eastern Advantage Assurance Company 
 Employers
Security Insurance Company (if it exists) 
 Eastern Re Ltd., S.P.C 

Because the management of the Eastern Group of Companies will not control investment and capital decisions it is appropriate to exclude these items and also
to exclude any purchase accounting related charges and any allocated overhead charges (which does not include either (1) overhead budgeted within Eastern’s projections or (2) any charges for direct expenses of Eastern) from the metric
used for compensation. 
 The combined ratio described herein will capture the entirety of the Eastern operations as set forth below: 

Loss and loss adjustment expenses + Acquisition Expenses + Operating Expenses + Policyholder Dividends – Ceding Commissions – Third
Party Administrator Revenue – Cell Rental Fees 
  
  

Net Earned Premiums 
 As an example here is the
calculation using Eastern’s March 31, 2013 Projections for 2014: 
  

									
	89,679 + 22,870 + 38,427 + 893 – 12,938 – 8,921 – 1,327	  		  	128,683	  		  	
	  
	  	=	  	  
	  	=	  	88.19%
		  	  		  		  	
	145,908	  		  	145,908
