SECTION 5.02. Unjustified Termination. Except as otherwise provided in Section 12.09, if the Employment Period shall be terminated (i) at the end of the Employment Period due to the Company giving written notice of non-extension pursuant to Section 5.01 above, or (ii) prior to the expiration of the original term (or the Employment Period as extended pursuant to Section 5.01) by the Executive for Good Reason or by the Company not for Cause (such terminations under clauses (i) and (ii) of this Section 5.02 are collectively referred to as “Unjustified Terminations”), the Executive shall be paid solely (except as provided in Section 5.04 below or as specifically provided in the Company’s Incentive Compensation Plan or successor plan) an amount equal to the greater of (i) eighteen (18) months of the Base Salary and (ii) the total remaining Base Salary for the Employment Period which would have been paid to the Executive under this Agreement if the Employment Period had not been so terminated, provided the Executive shall be entitled to such payments only if the Executive has not breached and does not breach in any material respect the provisions of Sections 6.01, 7.01, 8.01, 9.01 or 9.02 and the Executive has entered into a general release of claims reasonably satisfactory to the Company on or before the date that is fifty (50) days following the Date of Termination and does not revoke such release prior to the end of the statutory seven (7) day revocation period.  Subject to Section 12.09 below, such amounts will be paid as follows:  (A) an amount equal to twelve (12) months of the Base Salary shall be paid in twelve (12) equal installments, the first two (2) of which shall be paid on the date that is two (2) months following the Date of Termination and the next ten (10) of which will be paid in ten (10) equal monthly installments commencing on the date that is three (3) months following the Date of Termination and continuing on each of the next nine (9)

monthly anniversaries of the Date of Termination; and (B) the balance of the total amount payable under this Section 5.02 will be paid in a lump sum on the first anniversary of the Date of Termination.  In addition, promptly following an Unjustified Termination, the Executive shall also be reimbursed for all Reimbursable Expenses incurred by the Executive prior to such Unjustified Termination.  Notwithstanding any provision hereof to the contrary, in order for the Executive to terminate the Employment Period for Good Reason, such termination of employment must occur no later than sixty (60) days after the date the Executive gives written notice in accordance with Section 5.05 below to the Company of the occurrence of the event or condition that constitutes Good Reason.  Notwithstanding any provision of this Agreement to the contrary, for purposes of this Section 5.02 and the last sentence of Section 5.04, the Executive will be deemed to have terminated his employment on the date of his “separation from service” (within the meaning of Treasury Regulation Section 1.409A-1(h)) with the Company, the Employment Period will be deemed to have ended on the date of his “separation from service” with the Company, and the Date of Termination will be deemed to be the date of his “separation from service” with the Company.

SECTION 5.03. Justified Termination. If the Employment Period shall be terminated (i) prior to the expiration of the original term (or the Employment Period as extended pursuant to Section 5.01) (a) by the Company for Cause, (b) as a result of the Executive’s resignation or leaving of his employment, other than for Good Reason or (c) as a result of the death or Permanent Disability of the Executive, or (ii) at the end of the Employment Period as a result of the Executive’s provision of written notice not to extend the Employment Period under Section 5.01 (such terminations under clauses (i) and (ii) of this Section 5.03 are collectively referred to as “Justified Terminations”), the Executive shall be entitled to receive solely (except as provided in Section 5.04 below or as specifically provided in the Company’s Incentive Compensation Plan or successor plan) his Base Salary earned through the date of termination of employment and reimbursement of all Reimbursable Expenses incurred by the Executive prior to such Justified Termination.  If the termination is by reason of the death or Permanent Disability of the Executive, the Executive also shall be entitled to receive a prorated portion of his target annual bonus based on the number of days elapsed in the calendar year through the Date of Termination (offset by any life insurance proceeds received or disability insurance proceeds relating to periods following the date of termination of employment from any insurance coverages provided by the Company or any of its Affiliates), and such amount, if any, shall be paid to the Executive by no later than March 15 of the calendar year following the calendar year of such termination of employment.  For such purposes, the annual bonus shall not be less than the average annual bonus received for the preceding three years.

SECTION 5.04. Benefits. Except as otherwise required by mandatory provisions of law, all of the Executive’s rights to fringe and other benefits under this Agreement or otherwise, if any, accruing after the termination of the Employment Period as a result of a Justified Termination will cease upon such Justified Termination. Notwithstanding the foregoing, if such Justified Termination is a result of a Permanent Disability or if the Employment Period is terminated as a result of an Unjustified Termination, the Executive shall continue to receive his major medical insurance coverage benefits from the Company’s plan in effect at the time of such termination for a period equal to the lesser of (i) twelve (12) months after the Date of Termination, and (ii) until the Executive is provided by another employer with benefits

7

substantially comparable (with no pre-existing condition limitations) to the benefits provided by such plan.

SECTION 5.05.  Notice of Termination and Opportunity to Cure.  Any termination by the Company for Permanent Disability or Cause or without Cause or by the Executive for Good Reason shall be communicated by written Notice of Termination to the other party hereto.  For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the date the termination is to take effect (consistent with the terms of this Agreement), the specific termination provision in this Agreement relied upon and, for a termination for Permanent Disability or for Cause or for a resignation for Good Reason, shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of employment under the provision indicated.  It shall be a condition precedent to the Executive’s right to terminate employment for Good Reason that (i) the Executive shall first have given the Company written notice that an event or condition constituting Good Reason has occurred within ninety (90) days after such occurrence, and any failure to give such written notice within such period will result in a waiver by the Executive of his right to terminate for Good Reason as a result of such event or condition, and (ii) a period of thirty (30) days from and after the giving of such written notice shall have elapsed without the Company having effectively cured or remedied such occurrence during such 30-day period, unless such occurrence cannot be cured or remedied within thirty (30) days, in which case the period for remedy or cure shall be extended for a reasonable time (not to exceed an additional fifteen (15) days) provided that the Company has made and continues to make a diligent effort to effect such remedy or cure.

SECTION 12.09. 409A and 457A.  It is intended that this Agreement will comply with Sections 409A and 457A of the Internal Revenue Code of 1986, as amended (the “Code”) (and any regulations and guidelines issued thereunder), to the extent the Agreement is subject thereto, and the Agreement shall be interpreted on a basis consistent with such intent.  If an amendment of the Agreement is necessary in order for it to comply with Section 409A or Section 457A, the parties hereto will negotiate in good faith to amend the Agreement in a manner that preserves the original intent of the parties to the extent reasonably possible.  No action or failure to act, pursuant to this Section 12.09 shall subject the Company to any claim, liability, or expense, and the Company shall not have any obligation to indemnify or otherwise protect the Executive from the obligation to pay any taxes, interest or penalties pursuant to Section 409A or Section 457A of the Code.

Notwithstanding any provision to the contrary in this Agreement, if the Executive is deemed on the date of his “separation from service” (within the meaning of Treasury Regulation Section 1.409A-1(h)) to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then with regard to any payment that is required to be delayed pursuant to Section 409A(a)(2)(B) of the Code (after taking into account the applicable provisions of Treasury Regulation Section 1.409A-1(b)(9)(iii)), the portion, if any, of such payment so required to be delayed shall not be made prior to the earlier of (i) the expiration of the six (6)-month period measured from the date of his “separation from service” or (ii) the date of his death (the “Delay Period”).  Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum, and any remaining payments due under this Agreement shall be paid in accordance with the normal payment dates specified for them herein.  Whenever payments under this Agreement are to be made in installments, each such installment shall be deemed to be a separate payment for purposes of Section 409A of the Code.  In no case will compliance with this Section by the Company constitute a breach of the Company’s obligations under this Agreement.

With respect to any reimbursement or in-kind benefit arrangements of the Company and its subsidiaries provided for herein that constitute deferred compensation for purposes of Section 409A, except as otherwise permitted by Section 409A, the following conditions shall be applicable: (i) the amount eligible for reimbursement, or in-kind benefits provided, under any such arrangement in one calendar year may not affect the amount eligible for reimbursement, or in-kind benefits to be provided, under such arrangement in any other calendar year (except that the health and dental plans may impose a limit on the amount that may be reimbursed or paid), (ii) any reimbursement must be made on or before the last day of the calendar year following the calendar year in which the expense was incurred, and (iii) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.

SECTION 12.10. Excess Parachute Payments.

(a)           Notwithstanding any other provision of this Agreement, in the event that the amount of payments or other benefits payable to the Executive under this Agreement (including, without limitation, the acceleration of any payment or the accelerated vesting of any payment or other benefit), together with any payments, awards or benefits payable under any other plan, program, arrangement or agreement maintained by the Company or one of its Affiliates, would constitute an “excess parachute payment” (within the meaning of Section 280G of the Code), the payments under Section 5.02 of this Agreement shall be reduced (by the minimum possible amounts) until no amount payable to the Executive under this Agreement constitutes an “excess parachute payment” (within the meaning of Section 280G of the Code); provided, however, that no such reduction shall be made if the net after-tax payment (after taking into account federal, state, local or other income, employment and excise taxes) to which the Executive would otherwise be entitled without such reduction would be greater than the net after-tax payment (after taking into account federal, state, local or other income, employment and excise taxes) to the Executive resulting from the receipt of such payments with such reduction.

(b)           All determinations required to be made under this Section 12.10, including whether a payment would result in an “excess parachute payment” and the assumptions to be utilized in arriving at such determinations, shall be made by an accounting firm designated by the Company (the “Accounting Firm”) which shall provide detailed supporting calculations both to the Company and the Executive as requested by the Company or the Executive.  All fees and expenses of the Accounting Firm shall be borne solely by the Company and shall be paid by the Company.  Absent manifest error, all determinations made by the Accounting Firm under this Section 12.10 shall be final and binding upon the Company and the Executive.

SECTION 12.11. No Third Party Beneficiary. This Agreement will not confer any rights or remedies upon any person other than the Company, the Executive and their respective heirs, executors, successors and assigns.

SECTION 12.12. Entire Agreement. This Agreement (including the documents referred to herein) constitutes the entire agreement among the parties and supersedes any prior understandings, agreements or representations by or among the parties, written or oral, that may have related in any way to the subject matter hereof (except that the Agreement, between the Executive and Arch Insurance Group Inc, dated as of August 1, 2006 and amended as of November 24, 2008, shall remain in effect until the Start Date).  This Agreement shall serve as a written statement of employment for purposes of Section 6 of the Bermuda Employment Act 2000.

SECTION 12.13. Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rule of strict construction will be applied against any party. Any reference to any federal, state, local or foreign statute or law will be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. The use of the word “including” in this Agreement means including without limitation and is intended by the parties to be by way of

14

example rather than limitation.

SECTION 12.14. Survival. Sections 3.04, 5.02, 5.03, 5.04, 6.01, 7.01, 8.01 and Articles 9, 10, 11 and 12 will survive and continue in full force in accordance with their terms notwithstanding any termination of the Employment Period.

SECTION 12.15. GOVERNING LAW. ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND INTERPRETATION OF THIS AGREEMENT WILL BE GOVERNED BY THE INTERNAL LAW OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS.

SECTION 12.16. Jurisdiction. The parties agree to the nonexclusive jurisdiction of the federal and state courts situated in New York County, New York, for the resolution of any dispute arising under this Agreement or under any share-based award agreements between the Company and the Executive.
