(a) Base Salary. Employee shall be paid an annualized Base Salary, payable in accordance with the regular payroll practices of the Company, of not less than $229,100, subject to increase, if any, as may be approved in writing by the Company, but not to decrease from the then current Base Salary.

-4-

Section 7. Reimbursement of Business Expenses.

Employee is authorized to incur reasonable business expenses in carrying out his duties and responsibilities under this Agreement and the Company shall promptly reimburse him for all such reasonable business expenses incurred in connection with carrying out the business of the Company, subject to documentation in accordance with the Company’s policy, as in effect from time to time.

Section 8. Termination of Employment.

(a) General. The Term of Employment shall terminate upon the earliest to occur of (i) Employee’s death, (ii) a termination by reason of a Disability, (iii) a termination by the Company with or without Cause, and (iv) a termination by Employee with or without Good Reason. Upon any termination of Employee’s employment for any reason, except as may otherwise be requested by the Company in writing and agreed upon in writing by Employee, Employee shall resign from any and all directorships, committee memberships or any other positions Employee holds with any member of the Company Group. Notwithstanding anything herein to the contrary, the payment (or commencement of a series of payments) hereunder of any nonqualified deferred compensation (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as Employee has also undergone a

-5-

“separation from service” as defined in Treas. Reg. 1.409A-1(h), at which time such nonqualified deferred compensation (calculated as of the date of Employee’s termination of employment hereunder) shall be paid (or commence to be paid) to Employee on the schedule set forth in this Section 8 as if Employee had undergone such termination of employment (under the same circumstances) on the date of his ultimate “separation from service.”

(b) Termination due to Death or Disability. Employee’s employment shall terminate automatically upon his death. The Company may terminate Employee’s employment immediately upon the occurrence of a Disability, such termination to be effective upon Employee’s receipt of written notice of such termination. In the event Employee’s employment is terminated due to his death or Disability, Employee or his estate or his beneficiaries, as the case may be, shall be entitled to:

(i) The Accrued Obligations;

(ii) Any unpaid Annual Bonus in respect to any completed fiscal year which has ended prior to the date of such termination, such amount to be paid at the same time it would otherwise be paid to Employee had no such termination occurred, but in no event later than the last day of the Company’s fiscal year in which such termination occurs;

(iii) A pro rata Annual Bonus (determined using any target Annual Bonus if such termination occurs during the fiscal year in which the Closing Date falls, and using the highest Annual Bonus paid or payable for the two immediately prior fiscal years for terminations after the fiscal year in which the Closing Date falls) based on the number of days elapsed from the commencement of such fiscal year through and including the date of such termination, such amount to be paid within five (5) business days of such termination; and

(iv) Vesting, as of the date of such termination, in the number of equity-based awards, if any, which would otherwise have vested during the one (1) year period immediately following such termination (without regard to any subsequent vesting events).

Except as set forth in this Section 8(b), following Employee’s termination by reason of his death or Disability, Employee shall have no further rights to any compensation or any other benefits under this Agreement.

(i) A termination for Cause shall not take effect unless the provisions of this subsection (i) are complied with. Employee shall be given not less than fifteen (15) days prior written notice by the Company of the intention to terminate his employment for Cause, such notice to state in detail the particular act or acts or failure or failures to act that constitute the grounds on which the proposed termination for Cause is based. Employee shall have fifteen (15) days after the date that such written notice has been given to Employee in which to cure such act or acts or failure or failures to act, to the extent such cure is possible. If he fails to cure such act or acts or failure or failures to

-6-

act, the termination shall be effective on the date immediately following the expiration of the fifteen (15) day notice period. If cure is not possible, the termination shall be effective on the date of receipt of such notice by Employee. During any cure period provided hereunder, the Company may, in its sole and absolute discretion, prohibit Employee from entering the premises of any member of the Company Group or otherwise performing his duties hereunder, and any such prohibition shall in no event constitute an event pursuant to which Employee may terminate employment with Good Reason; provided, however, that if cure is possible, and Employee can reasonably demonstrate to the Company that he desires to enter the premises of any member of the Company Group or to otherwise perform his duties hereunder solely to attempt to cure the act or acts or failure or failures to act that constitute the grounds on which the proposed termination for Cause is based, Employee shall be permitted to enter the premises of any member of the Company Group or otherwise to perform his duties hereunder solely for the purposes of curing such act or acts or failure or failures to act.

(ii) In the event the Company terminates Employee’s employment for Cause, he shall be entitled only to the Accrued Obligations. Following such termination of Employee’s employment for Cause, except as set forth in this Section 8(c)(ii), Employee shall have no further rights to any compensation or any other benefits under this Agreement.

(d) Termination by the Company without Cause. The Company may terminate Employee’s employment at any time without Cause, effective upon Employee’s receipt of written notice of such termination. In the event Employee’s employment is terminated by the Company without Cause (other than due to death or Disability), Employee shall be entitled to:

(i) The Accrued Obligations;

(iii) An amount equal to the sum of his then current Base Salary and Annual Bonus (determined using any established target Annual Bonus if such termination occurs during the fiscal year in which the Closing Date falls, and using the highest Annual Bonus paid or payable for the two immediately prior fiscal years for terminations after the fiscal year in which the Closing Date falls), payable in substantially equal monthly installments over the Severance Term, it being agreed that each installment of Base Salary and Annual Bonus payable hereunder or under Section 8(e) shall be deemed to be a separate payment for purposes of Section 409A of the Code;

(iv) Continuation of participation under the Company’s health and other insurance plans during the Severance Term, or if such continued participation in is not permissible, provide Employee with coverage that is economically equivalent to Employee through alternative arrangements, or the cash value of such coverage, in a

-7-

manner that places the Employee in a net economic position that is at least equivalent to the position in which the Employee would have been had such alternative arrangements not been used by the Company; and

(v) Vesting, as of the date of such termination, in the number of equity-based awards, if any, which would otherwise have vested during the Severance Term (without regard to any subsequent vesting events).

Notwithstanding the foregoing, the payments and benefits described in subsections (ii) through (iv) above shall immediately cease, and the Company shall have no further obligations to Employee with respect thereto, in the event that Employee breaches any provision of Section 9 hereof.

Following such termination of Employee’s employment by the Company without Cause, except as set forth in this Section 8(d), Employee shall have no further rights to any compensation or any other benefits under this Agreement.

(e) Termination by Employee with Good Reason. Employee may terminate his employment with Good Reason by providing the Company fifteen (15) days prior written notice setting forth in reasonable specificity the event that constitutes Good Reason, which written notice, to be effective, must be provided to the Company within ninety (90) days of the occurrence of such event. During such fifteen (15) day notice period, the Company shall have a cure right (if curable), and if not cured within such period, Employee’s termination will be effective upon the date immediately following the expiration of the fifteen (15) day notice period, and Employee shall be entitled to the same payments and benefits as provided in Section 8(d) above for a termination without Cause, it being agreed that Employee’s right to any such payments and benefits shall be subject to the same terms and conditions as described in Section 8(d) above. Following such termination of Employee’s employment by Employee with Good Reason, except as set forth in this Section 8(e), Employee shall have no further rights to any compensation or any other benefits under this Agreement.

(f) Termination by Employee without Good Reason. Employee may terminate his employment without Good Reason by providing the Company thirty (30) days prior written notice of such termination. In the event of a termination of employment by Employee under this Section 8(f), Employee shall be entitled only to the Accrued Obligations. In the event of termination of Employee’s employment under this Section 8(f), the Company may, in its sole and absolute discretion, by written notice accelerate such date of termination and still have it treated as a termination without Good Reason. Following such termination of Employee’s employment by Employee without Good Reason, except as set forth in this Section 8(f), and, if applicable, such additional compensation and benefits described in Section 1(v)(iii), Employee shall have no further rights to any compensation or any other benefits under this Agreement.

(g) Release. Notwithstanding any provision herein to the contrary, the Company may require that, prior to payment of any amount or provision of any benefit pursuant to subsections (d) or (e) of this Section 8, Employee shall have executed a general release in favor of the Company and any other member of the Company Group and related parties in the

-8-

form as is reasonably required by the Company, and any waiting periods contained in such release shall have expired. Such release, if required by the Company, shall be delivered to Employee within twenty (20) business days following the termination of Employee’s employment hereunder, and failure to deliver such release within such twenty (20) business day period shall be deemed constitute a waiver of such requirement. Assuming delivery of the release by the Company, if Employee fails to execute such release on or prior to the Release Expiration Date, Employee shall not be entitled to any payments or benefits pursuant to (d) or (e) of this Section 8 (other than the Accrued Obligations). Notwithstanding anything contained in this subsection (g) to the contrary, in any case where the date of termination and last day of the applicable waiting period fall in two separate taxable years, any payments required to be made to Employee that are treated as deferred compensation for purposes of Section 409A of the Code shall be made in the later taxable year at times provided by this Section 8. For purposes of this Agreement, “Release Expiration Date” means the date which is twenty-one (21) days following the date upon which the Company delivers to Employee the release contemplated herein, or in the event that such termination of employment is “in connection with an exit incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), the date that is forty-five (45) days following such delivery date.

Section 9. Restrictive Covenants.

Employee acknowledges and agrees that (A) the agreements and covenants contained in this Section 9 are (i) reasonable and valid in geographical and temporal scope and in all other respects, and (ii) essential to protect the value of the business and assets of the Company Group; and (B) by his employment with the Company, Employee will obtain knowledge, contacts, know-how, training and experience and there is a substantial probability that such knowledge, contacts, know-how, training and experience could be used to the substantial advantage of a competitor of the Company Group and to the Company Group’s substantial detriment.

(a) Confidential Information. At any time during and after the end of the Term of Employment, without the prior written consent of the Company, except to the extent required by an order of a court having jurisdiction or under subpoena from an appropriate government agency, in which event, Employee shall, to the extent legally permitted, consult with the Company prior to responding to any such order or subpoena, and except as he in good faith believes necessary or desirable in the performance of his duties hereunder, Employee shall not disclose to or use for the benefit of any third party any confidential or proprietary trade secrets, customer lists, drawings, designs, information regarding product development (including types of insurance products), marketing plans, sales plans, management organization information, operating policies (including underwriting policies and risk assessment policies) or manuals, business plans, financial records, packaging design or other financial, commercial, business or technical information (i) relating to any member of the Company Group, or (ii) that any member of the Company Group may receive belonging to suppliers, customers or others who do business with any member of the Company Group (including insurance brokers) as a result of his position with any member of the Company Group (collectively, “Confidential Information”). Employee’s obligation under this Section 9(a) shall not apply to any information that is publicly available or hereafter becomes publicly available, in each case without the breach by Employee of this Section 9(a).

-9-

(b) Non-Competition. Employee covenants and agrees that during the Non-Compete Period, with respect to Bermuda (including any province thereof), any State of the United States of America or any other jurisdiction in which any member of the Company Group engages (or has committed plans to engage) in business during the Term of Employment, or, following termination of Employee’s employment, was engaged in business (or had committed plans to engage) at the time of such termination of employment, Employee shall not, directly or indirectly, individually or jointly, own any interest in, operate, join, control or participate as a partner, director, principal, officer, or agent of, enter into the employment of, act as a consultant to, or perform any services for any Person (other than any member of the Company Group), that engages in any Competitive Activities. Notwithstanding anything herein to the contrary, this Section 9(b) shall not prevent Employee from acquiring as an investment securities representing not more than three percent (3%) of the outstanding voting securities of any publicly-held corporation or from being a passive investor in any mutual fund, hedge fund, private equity fund or similar pooled account so long as Employee’s interest therein is less than three percent (3%) and he has no role in selecting or managing investments thereof.

(c) Non-Interference. During the Non-Interference Period, Employee shall not, directly or indirectly, for his own account or for the account of any other Person, engage in Interfering Activities.

(d) Return of Documents. In the event of the termination of Employee’s employment for any reason, Employee shall deliver to the Company all of (i) the property of any member of the Company Group, and (ii) the documents and data of any nature and in whatever medium of any member of the Company Group, and he shall not take with him any such property, documents or data or any reproduction thereof, or any documents containing or pertaining to any Confidential Information.

(e) Works for Hire. Employee agrees that the Company shall own all right, title and interest throughout the world in and to any and all inventions, original works of authorship, developments, concepts, know-how, improvements or trade secrets, whether or not patentable or registerable under copyright or similar laws, which Employee may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice during the Term of Employment, whether or not during regular working hours, provided they either (i) relate at the time of conception or development to the actual or demonstrably proposed business or research and development activities of any member of the Company Group; (ii) result from or relate to any work performed for any member of the Company Group; or (iii) are developed through the use of Confidential Information and/or Company resources or in consultation with personnel of any member of the Company Group (collectively referred to as “Developments”). Employee hereby assigns all right, title and interest in and to any and all of these Developments to the Company. Employee agrees to assist the Company, at the Company’s expense (but for no other consideration of any kind), to further evidence, record and perfect such assignments, and to perfect, obtain, maintain, enforce and defend any rights specified to be so owned or assigned. Employee hereby irrevocably designates and appoints the Company and its agents as attorneys-in-fact to act for and on Employee’s behalf to execute and file any document and to do all other lawfully permitted acts to further the purposes of the foregoing with the same legal force and effect as if executed by Employee. In addition, and not in contravention of any of the foregoing, Employee acknowledges that all original works of authorship which are made by

-10-

him (solely or jointly with others) within the scope of employment and which are protectable by copyright are “works made for hire,” as that term is defined in the United States Copyright Act (17 USC Sec. 101) or any similar law or regulation. To the extent allowed by law, this includes all rights of paternity, integrity, disclosure and withdrawal and any other rights that may be known as or referred to as “moral rights.” To the extent Employee retains any such moral rights under applicable law, Employee hereby waives such moral rights and consents to any action consistent with the terms of this Agreement with respect to such moral rights, in each case, to the full extent of such applicable law. Employee will confirm any such waivers and consents from time to time as requested by the Company.

(f) Blue Pencil. If any court of competent jurisdiction shall at any time deem the duration or the geographic scope of any of the provisions of this Section 9 unenforceable, the other provisions of this Section 9 shall nevertheless stand and the duration and/or geographic scope set forth herein shall be deemed to be the longest period and/or greatest size permissible by law under the circumstances, and the parties hereto agree that such court shall reduce the time period and/or geographic scope to a permissible duration or size.

Section 10. Breach of Restrictive Covenants.

Without limiting the remedies available to the Company, Employee acknowledges that a breach of any of the covenants contained in Section 9 hereof may result in material irreparable injury to the Company Group for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of such a breach or threat thereof, the Company shall be entitled to obtain a temporary restraining order and/or a preliminary or permanent injunction, without the posting of a bond or the necessity of proving irreparable harm or injury as a result of such breach or threatened breach of Section 9 hereof, restraining Employee from engaging in activities prohibited by Section 9 hereof or such other relief as may be required specifically to enforce any of the covenants in Section 9 hereof. Notwithstanding any other provision to the contrary, the Non-Compete Period, in the case of the covenants contained in Section 9(b), and the Non-Interference Period, in the case of the covenants contained in Section 9(c), shall be tolled during any period of violation of any of such covenants and during any other period required for litigation during which the Company seeks to enforce such covenants against Employee or another Person with whom Employee is affiliated if it is ultimately determined that Employee was in breach of such covenants.

Section 11. Representations and Warranties of Employee.

Employee represents and warrants to the Company that:

(a) Employee’s employment will not conflict with or result in his breach of any agreement to which he is a party or otherwise may be bound;

(b) Employee has not violated, and in connection with his employment with the Company will not violate, any non-solicitation, non-competition or other similar covenant or agreement of a prior employer by which he is or may be bound; and

-11-

(c) In connection with Employee’s employment with the Company, he will not use any confidential or proprietary information that he may have obtained in connection with employment with any prior employer.

Section 12. Indemnification.

Subject to the terms and conditions of the Certificate of Incorporation and Bylaws of the Company (in each case, as in effect from time to time), the Company agrees to indemnify and hold Employee harmless to the fullest extent permitted by the laws of the United States, as in effect at the time of the subject act or omission. In connection therewith, Employee shall be entitled to the protection of any insurance policies which the Company elects to maintain generally for the benefit of the Company’s directors and officers, against all costs, charges and expenses whatsoever incurred or sustained by Employee in connection with any action, suit or proceeding to which he may be made a party by reason of his being or having been a director, officer or employee of the Company. This provision shall survive any termination of Employee’s employment hereunder.

Section 13. Taxes.

The Company may withhold from any payments made under this Agreement all applicable taxes, including, but not limited to, income, employment and social insurance taxes, as shall be required by law.

Section 14. No Mitigation or Set Off.

Employee shall not be required to mitigate the amount of any payment provided for pursuant to this Agreement by seeking other employment or otherwise and the amount of any payment provided for pursuant to this Agreement shall not be reduced by any compensation earned as a result of Employee’s other employment or otherwise.

Section 15. Successors and Assigns; No Third-Party Beneficiaries.

(a) The Company. This Agreement shall inure to the benefit of and be enforceable by, and may be assigned by the Company to, any purchaser of all or substantially all of Holdings’ or the Company’s business or assets or any successor to Holdings or the Company (whether direct or indirect, by purchase, merger, consolidation or otherwise). Holdings or the Company will require, as applicable, in a writing delivered to Employee, any such purchaser, successor or assignee to expressly assume and agree to perform this Agreement in the same manner and to the same extent that Holdings and the Company would be required to perform it if no such purchase, succession or assignment had taken place. The Company may make no other assignment of this Agreement or its obligations hereunder.

(b) Employee. Employee’s rights and obligations under this Agreement shall not be transferable by Employee by assignment or otherwise, without the prior written consent of the Company; provided, however, that if Employee shall die, all amounts then payable to Employee hereunder shall be paid in accordance with the terms of this Agreement to Employee’s devisee, legatee or other designee or, if there be no such designee, to Employee’s estate.

-12-

(c) No Third-Party Beneficiaries. Except as otherwise set forth in Section 8(b) or Section 15(b) hereof, nothing expressed or referred to in this Agreement will be construed to give any Person other than the Company and Employee any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision of this Agreement.

Section 16. Delay in Payment.

Notwithstanding any provision in this Agreement to the contrary, but taking into account Treas. Reg. 1.409A-1(b) (9) (iii), any payment of nonqualified deferred compensation otherwise required to be made hereunder to Employee at any date as a result of the termination of Employee’s employment shall be delayed for such period of time as may be necessary to meet the requirements of Section 409A(a)(2)(B)(i) of the Code (the “Delay Period”). On the earliest date on which such payments can be made after the Delay Period, there shall be paid to the Employee, in a single cash lump sum, an amount equal to the aggregate amount of all payments delayed pursuant to the preceding sentence. Notwithstanding the foregoing, to the extent that the first sentence applies to the provision of any ongoing health and other insurance plan benefits, Employee shall pay the full cost for such health and other insurance plan benefits during the Delay Period and the Company shall pay Employee an amount equal to the amount of such premiums paid by Employee during the Delay Period within ten (10) days after the end of the Delay Period.

Section 17. Waiver and Amendments.

Any waiver, alteration, amendment or modification of any of the terms of this Agreement shall be valid only if made in writing and signed by each of the parties hereto.
