(a)During the Term of Employment, the Company shall pay or cause to be paid to Executive as base compensation for his or her services hereunder, in monthly installments, a base salary at a rate of $235,000 per annum, as increased on an annual basis to reflect the increase in the United States Cost of Living Index for

Notwithstanding the minimum increase set forth above, the Board of Directors of the Company or a committee thereof may establish a higher compensation level.

During the Term of Employment, the Company shall reimburse or cause Executive to be reimbursed for documented travel, entertainment and other expenses reasonably incurred by Executive in connection with the performance of his or her duties hereunder and, in each case, in accordance with applicable rules, customs and usages promulgated by the Companies from time to time in effect.

6.Benefits

During the Term of Employment, the Executive shall be entitled to perquisites, paid vacations and benefits (including health, short and long term disability, pension and life insurance benefits consistent with past practice, or as increased from time to time) established from time to time, by the Board of Directors of the Company for executives of the Companies, subject to the policies and procedures in effect regarding participation in such benefits.

7.Confidential Information

During and after the Term of Employment, Executive will not, directly or indirectly in one or a series of transactions, disclose to any person, or use or otherwise exploit for the Executive’s own benefit or for the benefit of anyone other than the Companies, any Confidential Information, whether prepared by Executive or not; provided, however, that any Confidential Information may be disclosed to officers, representatives, employees and agents of the Companies who need to know such Confidential Information in order to perform the services or conduct the operations required or expected of them in the Business (as defined in Section 11). Executive shall use his or her best efforts to prevent the removal of any Confidential Information from the premises of the Companies, except as required in his or her normal course of employment by the Company. Executive shall use commercially reasonable efforts to cause all persons or entities to whom any Confidential Information shall be disclosed by him or her hereunder to observe the terms and conditions set forth herein as though each such person or entity was bound hereby. Executive shall have no obligation hereunder to keep confidential any Confidential Information if and to the extent disclosure of any thereof is specifically required by law; provided, however, that in the event disclosure is required by applicable law, the Executive shall

provide the Companies with prompt notice of such requirement, prior to making any disclosure, so that the Companies may seek an appropriate protective order. At the request of the Companies, Executive agrees to deliver to the Companies, at any time during the Term of Employment, or thereafter, all Confidential Information which he or she may possess or control.  Executive agrees that all Confidential Information of the Companies (whether now or hereafter existing) conceived, discovered or made by him or her during the Term of Employment exclusively belongs to the Companies (and not to Executive). Executive will promptly disclose such Confidential Information to the Companies and perform all actions reasonably requested by the Companies to establish and confirm such exclusive ownership.

8.Non-Interference

(a)Executive acknowledges that the services to be provided give him or her the opportunity to have special knowledge of the Companies and their Confidential Information and the capabilities of individuals employed by or affiliated with the Companies and that interference in these relationships would cause irreparable injury to the Companies. In consideration of this Agreement, Executive covenants and agrees that:

(i)During the Restricted Period (which shall not be reduced by any period of violation of this Agreement by Executive or period which is required for litigation to enforce the rights hereunder), Executive will not, without the express written approval of the Board of Directors of the Company, anywhere in the Market, directly or indirectly, in one or a series of transactions, own, manage, operate, control, invest or acquire an interest in, or otherwise engage or participate in, whether as a proprietor, partner, stockholder, lender, director, officer, employee, joint venturer, investor, lessor, supplier, customer, agent, representative or other participant, in any business which competes, directly or indirectly, with the Business in the Market (“Competitive Business”) without regard to (A) whether the Competitive Business has its office, manufacturing or other business facilities within or without the Market, (B) whether any of the activities of the Executive referred to above occur or are performed within or without the Market or (C) whether the Executive resides, or reports to an office, within or without the Market; provided, however, that (x) the Executive may, anywhere in the Market, directly or indirectly, in one or a series of transactions, own, invest or acquire an interest in up to five percent (5%) of the capital stock of a corporation whose capital stock is traded publicly, or that (y) Executive may accept employment with a successor company to the Company.

(ii)During the Restricted Period (which shall not be reduced by any period of violation of this Agreement by Executive or period which is required for litigation to enforce the rights hereunder), Executive will not without the express prior written approval of the Board of Directors of the Company (A) directly or indirectly, in one or a series of transactions, recruit, solicit or otherwise induce or influence any proprietor, partner, stockholder, lender, director, officer, employee, sales agent, joint venturer, investor, lessor, supplier, customer, agent, representative or any other person which has a business relationship with the Companies or had a business relationship with the Companies within the 24 month period preceding the date of the incident in question, to discontinue, reduce or modify such employment, agency or business relationship with the Companies, or (B) employ or seek to employ or cause any Competitive Business to employ or seek to employ any person or agent who is then (or was at any time within 24 months prior to the date the Executive or the Competitive Business employs or seeks to employ such person) employed or retained by the Companies.  Notwithstanding the foregoing, nothing herein shall prevent the Executive from providing a letter of recommendation to an employee with respect to a future employment opportunity.

(iii)The scope and term of this Section 8 would not preclude Executive from earning a living with an entity that is not a Competitive Business.

(b)In the event that Executive breaches his or her obligations in any material respect under Section 7, this Section 8 or Section 9, the Company, in addition to pursuing all available remedies under this Agreement, at law or otherwise, and without limiting its right to pursue the same shall cease or cause to be ceased all payments to the Executive under this Agreement or any other agreement.

9.Non-Disparagement

During and after the Term of Employment, the Executive agrees that he or she shall not make any false, defamatory or disparaging statements about the Companies or the officers or directors of the Companies. During and after the Term of Employment, the Company agrees, on behalf of the Companies that neither the officers nor the directors of the Companies shall make any false, defamatory or disparaging statements about the Executive.

10.Code Section 280G Cutback

(a)If any payments or benefits paid or provided or to be paid or provided to the Executive or for his or her benefit pursuant to the terms of this Agreement or otherwise in connection with, or arising out of, his or her employment with the Company or the termination thereof (a “Payment”) would be subject to the excise tax (the “Excise Tax”) imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), then the Payments shall be reduced to the extent necessary to prevent any portion of the Payments from becoming nondeductible by the Company under Section 280G of the Code or subject to the Excise Tax, but only if, by reason of that reduction, the net after-tax benefit received by the Executive exceeds the net after-tax benefit the Executive would receive if no reduction was made. For this purpose, “net after-tax benefit” means (i) the total of all Payments that would constitute “excess parachute payments” within the meaning of Section 280G of the Code, less (ii) the amount of all federal, state, and local income taxes payable with respect to the Payments calculated at the maximum marginal income tax rate for each year in which the Payments shall be paid to the Executive (based on the rate in effect for that year as set forth in the Code as in effect at the time of the first payment of the Payments), less (iii) the amount of the Excise Tax imposed on the Payments described in clause (i) above. If a reduction in Payments is necessary under this Section 10(a), the reduction shall be made in a manner set forth in (b).

(b)Any reduction of the Payments required under Section 10(a) shall be made in the following order: (i) first, any cash amounts payable to the Executive as a severance benefit as provided in Section 3(f)(ii), (g)(ii), (h)(ii), or (i)(ii) or otherwise; (ii) second, any amounts payable on behalf of the Executive for continued health insurance coverage under Section 3(f)(iii), g(iii), h(iii), or i(iii) or otherwise; (iii) third, any other cash amounts payable to or on behalf of the Executive under the terms of this Agreement or otherwise; (iv) fourth, any outstanding performance-based equity grants; and (v) finally, any time-vesting equity grants; in each case, the Payments shall be reduced beginning with Payments that would be made last in time.

(c)All determinations required to be made under this Section 10 shall be made by the public accounting firm that is retained by the Company (the “Accounting Firm”). The Accounting Firm shall provide detailed supporting calculations both to the Company and Executive within fifteen (15) business days of the receipt of notice from the Company or Executive that there has been a Payment, or such earlier time as is requested by the Company. All fees, costs and expenses (including, but not limited to, the costs of retaining experts) of the Accounting Firm shall be borne by the Company. The determination by the Accounting Firm shall be binding upon the Company and Executive.

Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.  If any court determines that any provision of Section 8 or any other provision hereof is unenforceable and therefore acts to reduce the scope or duration of such provision, the provision in its reduced form shall then be enforceable.

17.Waiver of Breach; Specific Performance

The waiver by the Company or Executive of a breach of any provision of this Agreement by the other party shall not operate or be construed as a waiver of any other breach of such other party. Each of the parties (and third party beneficiaries) to this Agreement will be entitled to enforce its respective rights under this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of Sections 7, 8 and 9 of this Agreement and that any party (and third party beneficiaries) may in its sole discretion apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions in order to enforce or prevent any violations of the provisions of this Agreement. In the event either party takes legal action to enforce any of the terms or provisions of this Agreement, the nonprevailing party shall pay the successful party’s costs and expenses, including but not limited to, attorneys’ fees, incurred in such action. If the Executive prevails, the Company will reimburse the Executive’s legal fees no later than 60 days after the end of the taxable year following the year in which the Executive incurs such the costs and expenses.

18.Assignment; Third Parties

Neither the Executive nor the Company may assign, transfer, pledge, hypothecate, encumber or otherwise dispose of this Agreement or any of his or her or its respective rights or obligations hereunder, without the prior written consent of the other. The parties agree and acknowledge that each of the Companies and the stockholders and investors therein are intended to be third party beneficiaries of, and have rights and interests in respect of, Executive’s agreements set forth in Sections 7, 8 and 9.

19.Amendment; Entire Agreement

This Agreement may not be changed orally but only by an agreement in writing agreed to by the party against whom enforcement of any waiver, change, modification, extension or discharge is sought. This

Agreement embodies the entire agreement and understanding of the parties hereto in respect of the subject matter of this Agreement, and supersedes and replaces all prior agreements, understandings and commitments with respect to such subject matter, including, without limitation, the Prior Employment Agreement and that certain Employment Agreement, between Executive and Safety Insurance Company.

20. Litigation

THIS AGREEMENT SHALL BE GOVERNED BY, CONSTRUED, APPLIED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS, EXCEPT THAT NO DOCTRINE OF CHOICE OF LAW SHALL BE USED TO APPLY ANY LAW OTHER THAN THAT OF MASSACHUSETTS, AND NO DEFENSE, COUNTERCLAIM OR RIGHT OF SET-OFF GIVEN OR ALLOWED BY THE LAWS OF ANY OTHER STATE OR JURISDICTION, OR ARISING OUT OF THE ENACTMENT, MODIFICATION OR REPEAL OF ANY LAW, REGULATION, ORDINANCE OR DECREE OF ANY FOREIGN JURISDICTION, BE INTERPOSED IN ANY ACTION HEREON. EXECUTIVE AND THE COMPANY AGREE THAT ANY ACTION OR PROCEEDING TO ENFORCE OR ARISING OUT OF THIS AGREEMENT SHALL BE COMMENCED IN THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS LOCATED IN BOSTON, MASSACHUSETTS OR THE UNITED STATES DISTRICT COURTS IN BOSTON, MASSACHUSETTS. EXECUTIVE AND THE COMPANY CONSENT TO SUCH JURISDICTION, AGREE THAT VENUE WILL BE PROPER IN SUCH COURTS AND WAIVE ANY OBJECTIONS BASED UPON FORUM NON CONVENIENS.  THE CHOICE OF FORUM SET FORTH IN THIS SECTION 20 SHALL NOT BE DEEMED TO PRECLUDE THE ENFORCEMENT OF ANY JUDGMENT OBTAINED IN SUCH FORUM OR THE TAKING OF ANY ACTION UNDER THIS AGREEMENT TO ENFORCE SAME IN ANY OTHER JURISDICTION.

21.Further Action

Executive and the Company agree to perform any further acts and to execute and deliver any documents which may be reasonable to carry out the provisions hereof.
