Dear Michael:

This letter agreement (the “Letter Agreement”) amends and restates in its entirety the letter agreement between you and Platinum Underwriters Holdings, Ltd. (the “Company”) dated July 24, 2008, as amended on October 29, 2009.

Your employment hereunder shall commence on the date hereof and, subject to termination as provided in Section 10 hereof, shall end on July 31, 2013; provided that, on August 1, 2013 and on each August 1 thereafter, the term of your employment shall automatically be extended by an additional year unless you or the Company gives the other party written notice, at least 120 days prior to the end of the current term, that you or the Company has determined that the term shall not be so extended. Such employment period, as extended, shall hereinafter be referred to as the “Term.”

(a) During the Term, you will serve as Chief Executive Officer of the Company. You will have such duties, responsibilities, power and authority as those normally associated with such position, plus any additional duties, responsibilities, power and authority assigned to you by the Board of Directors of the Company (the “Board”).

(b) Your principal place of employment shall be at the Company’s corporate headquarters in Bermuda or such other location as the Board shall establish for the Company’s corporate headquarters, although you understand and agree that you may be required to travel from time to time for business reasons. The performance of your duties and responsibilities shall be conducted in a manner consistent with any tax operating guidelines which may be promulgated from time to time by the Board.

During the Term, the Company shall pay you a base salary (“Base Salary”) at an annual rate of US$980,000 for the period from the date hereof through July 31, 2011, and at an annual rate of US$900,000 beginning on August 1, 2011, payable in cash in accordance with the Company’s payroll practices as in effect from time to time.

During each calendar year of the Term, you shall be eligible for an annual performance bonus (“Annual Bonus”) pursuant to the terms of the Company’s Amended and Restated Annual Incentive Plan (the “AIP”). Your Annual Bonus shall have an incentive target equal to 150% of Base Salary (the “Target Bonus”). You will be eligible for an Annual Bonus equal to the Target Bonus multiplied by the “Performance Bonus Multiplier” as defined in the AIP (the “Formula Bonus Amount”); provided, however, that the Compensation Committee of the Board (the “Committee”) will, in its sole discretion, determine the actual Annual Bonus paid to you. The Performance Bonus Multiplier shall be a percentage, ranging from 0% to 200%, depending on the “Performance Goals” relative to the “Performance Criteria,” as such terms are defined in the AIP, all as established by the Committee for all participants in the AIP. Your Annual Bonus shall be paid in accordance with the terms of the AIP following the end of the calendar year to which it relates, subject to such terms and conditions as the Committee shall require. Pursuant to the terms of the AIP, payment of your Annual Bonus shall be made in cash, restricted share units or a combination thereof, as may be determined by the Committee in its sole discretion at the time of payment. Notwithstanding the foregoing or anything in the AIP to the contrary, (i) as long as you are in compliance with the Share Ownership Guidelines adopted by the Board (as they may be amended from time to time by the Board, the “Guidelines”), the Annual Bonus shall be paid 100% in cash, and (ii) in the event that your employment terminates upon the expiration of the Term, you shall be entitled to receive a prorated Annual Bonus for the period from January 1 through July 31 of the year of such termination in cash in an amount equal to 7/12ths of the Formula Bonus Amount for such year, subject to modification in the sole discretion of the Committee, payable at the time provided for in Section 14 hereof (the “Prorated Bonus Payment”), provided that such payment shall be conditioned upon compliance with Section 15 hereof.

During the Term, you shall be a participant in the Company’s Amended and Restated Executive Incentive Plan (the “EIP”). On or prior to February 28 of each calendar year during the Term, you will be eligible for an award under the EIP (each, an “EIP Award”) of that number of share units under the EIP equal to 100% of your Base Salary divided by the Fair Market Value (as defined in the 2010 Share Incentive Plan) of a Common Share (as defined below) on the date of grant of such EIP Award, with a Performance Cycle (as defined in the EIP) of three years. The actual amount, terms and conditions and the form of payment of any EIP Award will be determined by the Committee in its sole discretion, in accordance with the terms of the EIP. In the event that your employment with the Company terminates upon the expiration of the Term, you shall be entitled to receive payment in respect of each EIP Award on a prorated basis based on your period of service with the Company and the performance levels achieved by the Company for the Performance Cycle as of the end of the fiscal quarter preceding the termination of your employment with the Company, provided that such payment shall be conditioned upon compliance with Section 15 hereof. The terms and conditions, including the date and the form of payment, of each EIP Award shall be determined by the Committee in its sole discretion, in accordance with the terms of the EIP and the award agreement reflecting such EIP Award.

Prior to the date hereof, you had achieved your required share ownership level of 100,000 common shares, par value US$0.01 per share, of the Company (the “Common Shares”) under the Guidelines. You shall be required to maintain such level during the Term, subject to certain exceptions set forth in the Guidelines.

During the Term, you shall be eligible to participate in the employee benefit plans and arrangements that are generally available to senior executives of the Company, subject to the terms and conditions of such plans and arrangements. The Board reserves the right to amend or terminate any employee benefit plan or arrangement at any time, and to adopt any new plan or arrangement.

(a) The Company shall reimburse you and your family for first-class roundtrip air travel to the United States on up to four occasions per year through 2010 and on up to two occasions in 2011 through July 31, 2011.

(b) The Company shall provide you with a housing allowance of US$40,000 per month and a car allowance of US$700 per month (or such higher housing or car allowances as are approved by the Committee) through July 31, 2011, and during the Term thereafter the Company shall provide you with a housing allowance of US$10,000 per month (or such higher housing allowance as is approved by the Committee).

(c) The Company shall pay any fees and expenses, including legal expenses, incurred in connection with obtaining and maintaining for you any work permits required by the Bermuda governmental authorities.

(d) The Company shall reimburse you up to a maximum of US$50,000 for the costs and expenses incurred by you (including duty taxes) in connection with the relocation of your family from Bermuda.

(e) Commencing August 1, 2011, the Company shall provide travel by a corporate jet for up to twenty-four (24) round trips per year (prorated for 2011 and any partial calendar year during the Term) for your travel between your home in the United States and the Company’s corporate headquarters in Bermuda or such other location as the Board shall establish for the Company’s corporate headquarters.

(f) You shall be responsible for any tax liability associated with any payments or reimbursements under this Section 8.

During the Term, the Company shall reimburse you for all reasonable expenses incurred by you in carrying out your duties and responsibilities under this Letter Agreement in accordance with the Company’s policies for senior executives as in effect from time to time.

(a) Termination for Good Reason; Termination Without Cause. If you terminate your employment during the Term for Good Reason (as defined below) or if your employment is terminated during the Term by the Company without Cause (as defined below), (i) you shall receive a lump sum cash payment equal to the sum of (A) US$2,250,000 and (B) any earned but unpaid Base Salary and other amounts (including reimbursable expenses and any vested amounts or benefits under the Company’s employee benefit plans or arrangements) accrued or owing through the date of effectiveness of such termination under the terms of the applicable arrangement; (ii) all unvested equity awards held by you (other than awards under the EIP) shall vest and/or become fully exercisable, (iii) you shall be entitled to receive a prorated Annual Bonus for the calendar year in which the termination of your employment occurred (the “AIP Payment”) equal to the Formula Bonus Amount for such calendar year multiplied by a fraction the numerator of which is the number of days of your service with the Company in such calendar year and the denominator of which is 365; and (iv) your entitlement to payments in respect of outstanding awards under the EIP shall be determined in accordance with the terms thereof. Payment and vesting of any amount under this Section 10(a) shall be subject to the provisions of Sections 14 and 15 hereof. The parties hereto acknowledge that the Company’s Change in Control Severance Plan provides that any amounts payable to you pursuant to any other plan or agreement with the Company on account of the termination of your employment, including, without limitation, this Letter Agreement, shall be offset against any payments made to you pursuant to the Company’s Change in Control Severance Plan to the extent necessary to avoid duplication of benefits.

(b) Termination Other than for Good Reason; Termination for Cause. If you terminate your employment during the Term other than for Good Reason or if your employment is terminated during the Term by the Company for Cause, all unvested equity awards (including all outstanding awards under the EIP) and your entitlement to an Annual Bonus for the calendar year in which the termination of your employment occurred shall be forfeited, and you shall receive no further payments, compensation or benefits under this Letter Agreement, except you shall receive, upon the effectiveness of such termination, any earned but unpaid Base Salary and other amounts (including reimbursable expenses and any vested amounts or benefits under the Company’s employee benefit plans or arrangements) accrued or owing through the date of effectiveness of such termination under the terms of the applicable arrangement.

(c) Death or Disability. Upon the termination of your employment during the Term on account of your death or Disability (as defined below), (i) you or your beneficiaries shall receive any earned but unpaid Base Salary and other amounts (including reimbursable expenses and any vested amounts or benefits under the Company’s employee benefit plans or arrangements) accrued or owing through the date of effectiveness of such termination under the terms of the applicable arrangement; (ii) all unvested equity awards held by you (other than awards under the EIP) that would have vested or that would have become exercisable within one year after your death or Disability shall vest and/or become fully exercisable, and (iii) your entitlement to payments in respect of outstanding awards under the EIP shall be determined in accordance with the terms thereof. Payment and vesting of any amount under this Section 10(c) shall be conditioned upon compliance with Section 15 hereof.

(d) Non-Extension. In the event that your employment with the Company terminates upon the expiration of the Term, you shall be entitled to receive (i) a prorated Annual Bonus in accordance with Section 4(ii) hereof, (ii) payment in respect of each EIP Award in accordance with Section 5 hereof, and (iii) any earned but unpaid Base Salary and other amounts (including reimbursable expenses and any vested amounts or benefits under the Company’s employee benefit plans or arrangements) accrued or owing through the date of effectiveness of such termination under the terms of the applicable arrangement. Payment and vesting of any amount under this Section 10(d) shall be conditioned upon compliance with Section 15 hereof.

(e) Definitions. For purposes of this Letter Agreement, the terms set forth below shall have the following meanings:

(i) “Cause” means (A) your willful and continued failure to substantially perform your duties hereunder; (B) your conviction of, or plea of guilty or nolo contendere to, a felony or other crime involving moral turpitude; (C) your engagement in any malfeasance or fraud or dishonesty of a substantial nature in connection with your position with the Company or any of its subsidiaries, or other willful act that materially damages the reputation of the Company or any of its subsidiaries; (D) your breach of any restrictive covenants in Section 11 hereof or in any option or other award agreement between you and the Company; or (E) the sale, transfer or hypothecation by you during the Term of Common Shares in violation of the Guidelines; provided, however, that no such act, failure to act or event that is capable of being cured by you shall be treated as “Cause” under this Letter Agreement unless you have been provided a detailed, written statement of the basis for the Company’s belief that such act, failure to act or event constitutes “Cause” and have had at least thirty (30) days after receipt of such statement to cure such act, failure to act or event. For purposes of this Section 10(e)(i), no act or failure to act shall be considered “willful” unless it is done, or failed to be done, in bad faith, and without reasonable belief that the act or failure to act was in the best interest of the Company.

(ii) “Good Reason” means, without your express written consent, (A) the Company reduces your Base Salary or your Target Bonus other than as provided in Section 3 hereof; (B) the Company reduces the scope of your duties, responsibilities, power or authority; (C) you are required to report to anyone other than the Board; (D) the Company requires your principal place of employment to be at a location other than Company’s corporate headquarters in Bermuda or such other location as the Board shall establish for the Company’s headquarters; or (E) the Company breaches any other material provision of this Letter Agreement; provided, however, that if you voluntarily consent to any reduction or change described above in lieu of exercising your right to resign for Good Reason, and deliver such consent to the Company in writing, then such reduction or change shall not constitute “Good Reason” hereunder, but you shall have the right to resign for Good Reason under this Letter Agreement as a result of any subsequent reduction or change described above.

(iii) “Disability” means a termination of your employment by the Company, if you have been rendered incapable of performing your duties by reason of any medically determined physical or mental impairment that can be expected to result in death or that can be expected to last for a period of either (A) six or more consecutive months from the first date of your absence due to the disability or (B) nine or more months during any twelve-month period.

In exchange for the remuneration outlined above, in addition to providing services to the Company as set forth in this Letter Agreement, you agree to the following covenants, which you agree are intended to survive the Term and any termination or expiration of this Letter Agreement:

(a) Confidentiality. During the period of your employment and for all periods following any termination of your employment for any reason, you shall keep confidential any trade secrets and confidential or proprietary information of the Company (and its subsidiaries and affiliates) which are now known to you or which hereafter may become known to you as a result of your employment or association with the Company, and shall not at any time, directly or indirectly, disclose any such information to any person, firm or corporation, or use the same in any way other than in connection with the business of the Company (or its subsidiaries or affiliates) during, and at all times after, the termination of your employment. For purposes of this Letter Agreement, “trade secrets and confidential or proprietary information” means information unique to the Company (or its subsidiaries or affiliates) which has a significant business purpose and is not known or generally available from sources outside the Company (or its subsidiaries or affiliates) or typical of industry practice, but shall not include any of the foregoing (i) information that becomes a matter of public record or is published in a newspaper, magazine or other periodical available to the general public, other than as a result of any act or omission by you or (ii) information that is required to be disclosed by any law, regulation or order of any court or regulatory commission, department or agency, provided that you give prompt notice of such requirement to the Company to enable the Company (or its subsidiaries or affiliates) to seek an appropriate protective order or confidential treatment.

(b) Return of Company Information. In the event of the termination of your employment for any reason, you shall deliver to the Company all of (i) the property of the Company (and its subsidiaries and affiliates) and (ii) the documents and data of any nature and in whatever medium of the Company (and its subsidiaries and affiliates), and you shall not take with you any such property, documents or data, or any reproduction thereof, or any documents containing or pertaining to any trade secrets and confidential or proprietary information of the Company (and its subsidiaries and affiliates) as defined in paragraph (a) above.

(c) Non-Solicitation and Non-Hire. You covenant that during the period of your employment with the Company and during the twenty-four month period following termination of such employment for any reason (the “Restricted Period”), you shall not, without the prior written consent of the Governance Committee of the Board, directly or indirectly, solicit, hire or cause to be solicited or hired by an enterprise with which you may ultimately become associated, any employee of the Company (or its subsidiaries or affiliates) whose annual compensation exceeds US$100,000.

(d) Non-Competition. You covenant that during the period of your employment with the Company and during the Restricted Period, you shall not, without the prior written consent of the Governance Committee of the Board, directly or indirectly, engage in, hold an interest in, own, manage, operate, control, direct, be connected with as a stockholder (other than as a holder of less than two percent (2%) of a publicly-traded security), joint venturer, partner, consultant or employee, or otherwise engage or participate in or be connected in any manner with, (i) any reinsurance business, (ii) any business directly engaged in the sale of derivatives used primarily as an alternative to reinsurance, or (iii) any insurance business that competes with any insurance business engaged in by the Company or any of its subsidiaries or in which the Company or any of its subsidiaries have plans to engage, in either case at the time of the termination of your employment.

(e) Non-Disparagement. You agree that you shall not at any time following the date hereof engage in any conduct with the intent to injure, or make any statements or express any views that disparage, the business reputation or interests of the Company or its subsidiaries or any of their respective directors and officers. The Company agrees that the Company, its subsidiaries and their respective directors and officers shall not at any time following the date hereof engage in any conduct with the intent to injure, or make any statements or express any views that disparage, you, your business reputation or interests. Notwithstanding the foregoing, this Section 11(e) shall not apply to truthful communications the respective parties are required by law to make to any governmental, regulatory or self-regulatory entity.

(f) Enforcement. You acknowledge that if you breach any provision of this Section 11, the Company (or its subsidiaries or affiliates) will suffer irreparable injury. It is therefore agreed that the Company (or its subsidiaries or affiliates) shall have the right to enjoin any such breach, without posting any bond, if permitted by a court of the applicable jurisdiction. You hereby waive the adequacy of a remedy at law as a defense to such relief. The existence of this right to injunctive or other equitable relief shall not limit any other rights or remedies which the Company (or its subsidiaries or affiliates) may have at law or in equity, including, without limitation, the right to monetary, compensatory and punitive damages. You acknowledge and agree that the provisions of this Section 11 are reasonable and necessary for the successful operation of the Company. In the event an arbitrator or a court of competent jurisdiction determines that you have breached your obligations in any material respect under this Section 11, the Company, in addition to pursuing all available remedies under this Letter Agreement, at law or otherwise, and without limiting its right to pursue the same, shall cease all payments to you under this Letter Agreement. If any provision of this Section 11 is determined by a court of competent jurisdiction to be not enforceable in the manner set forth in this Letter Agreement, you and the Company agree that it is the intention of the parties that such provision should be enforceable to the maximum extent possible under applicable law. If any provisions of this Section 11 are held to be invalid or unenforceable, such invalidation or unenforceability shall not affect the validity or enforceability of any other provision of this Letter Agreement (or any portion thereof).

For a period of five years following any termination of your employment with the Company, you agree to reasonably cooperate with and assist the Company (and its subsidiaries and affiliates) in any matter or dispute in which the Company (and its subsidiaries and affiliates) is involved or may be involved in the future, and in which you may have been involved. Such cooperation and assistance shall be provided at a time and in a manner which are mutually and reasonably agreeable to you and the Company, and shall include, without limitation, providing information, documents and testimony, submitting to depositions, and generally cooperating to assist the Company (and its subsidiaries and affiliates). After the first 50 hours of such cooperation, which shall be provided by you for no compensation other than as provided in the last sentence of this Section 12, the Company shall pay you US$500 per hour for any such cooperation, payable within thirty days following the provision of such cooperation. The Company shall also reimburse you for reasonable out-of-pocket expenses in connection with such cooperation.

(a) All compensation paid to you under this Letter Agreement shall be subject to all applicable income tax, employment tax and other non-U.S. and U.S. federal, state and local tax withholdings and deductions.

(b) This Letter Agreement constitutes the entire agreement between you and the Company with respect to the subject matter hereof and supercedes any and all prior agreements or understandings between you and the Company or any of its subsidiaries or affiliates with respect to the subject matter hereof; provided, however, that this Letter Agreement shall not have any impact on any outstanding awards granted to you under any bonus, incentive or equity-based compensation plan of the Company, and shall not affect your participation in any such plan or other employee benefit of the Company (including, without limitation, the Change in Control Severance Plan), except in each case to the extent explicitly set forth in this Letter Agreement. Any amendment or termination of this Letter Agreement must be in writing and signed by you and the Company.

(c) This Letter Agreement may be executed in any number of counterparts which together shall constitute but one agreement.

(d) This Letter Agreement shall be binding on and inure to the benefit of the Company’s successors and permitted assigns and, in your case, your estate, heirs and legal representatives. Other than as provided herein, the rights and obligations described in this Letter Agreement may not be assigned by you without the prior written consent of the Governance Committee of the Board, and may not be assigned by the Company without your prior written consent.

(e) Subject to Section 11(f) hereof, all disputes arising under or related to this Letter Agreement shall be settled by arbitration under the Commercial Arbitration Rules of the American Arbitration Association then in effect as the sole and exclusive remedy of either party. Such arbitration shall be held in New York City. Any judgment on the award rendered by such arbitration may be entered in any court having jurisdiction over such matters. Each party’s costs and expenses of such arbitration, including reasonable attorney fees and expenses, shall be borne by such party.

(f) All notices under this Letter Agreement shall be in writing and shall be deemed effective when delivered in person, or five (5) days after deposit thereof in the mail, postage prepaid, for delivery as registered or certified mail, addressed to the respective party at the address set forth below or to such other address as may hereafter be designated by like notice. Unless otherwise notified as set forth above, notice shall be sent to each party as follows:

In lieu of personal notice or notice by deposit in the mail, a party may give notice by confirmed fax or e-mail, which shall be effective upon receipt.

(g) This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York without reference to rules relating to conflict of laws.

(h) This Letter Agreement supercedes any inconsistent provisions of any plan or arrangement that would otherwise be applicable to you to the extent such provisions would limit any rights granted to you hereunder or expand any restrictions imposed on you hereby.

(i) To the extent that the terms “Cause” and “Good Reason” are used in the EIP Share Unit Award Agreements dated as of February 21, 2008, February 23, 2009 and February 22, 2010, the Restricted Share Award Agreements dated as of August 1, 2008 and October 29, 2009, or any other award agreements, between you and the Company, such award agreements shall be deemed to be amended so that such terms shall have the meanings given thereto in this Letter Agreement or in any other employment agreement between you and the Company as may be in effect from time to time.

(a) Subject to any delay required by Section 14(b) hereof, all payments or vesting rights provided under Section 10(a), 10(c) and 10(d) hereof shall be paid or vest on the date that is sixty (60) days following your “separation from service” (within the meaning of Treas. Reg. Section 1.409A-1(h)); provided, however, that (i) the timing of payments governed by a separate award agreement shall be determined by such award agreement, and (ii) any payment pursuant to the terms of the AIP (including the Prorated Bonus Payment and the AIP Payment) shall in all events be made in the calendar year immediately following the calendar year in which the bonus was earned.

(b) To the extent applicable, the provisions of this Letter Agreement and any payments made pursuant hereto are intended to comply with, and should be interpreted consistent with, the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and any related regulations or other effective guidance promulgated thereunder (collectively, “Section 409A”), and Section 457A of the Code and any related regulations or other effective guidance promulgated thereunder (collectively, “Section 457A”). The time or schedule of a payment to which you are entitled under this Letter Agreement may be accelerated at any time that this Letter Agreement fails to meet the requirements of Section 409A and any such payment will be limited to the amount required to be included in your income as a result of the failure to comply with Section 409A. If an amendment of the Letter 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 Letter Agreement in a manner that preserves the original intent of the parties to the extent reasonably possible. Notwithstanding any provision in this Letter Agreement to the contrary, if you are a “specified employee” (within the meaning of Section 409A) on the date of your “separation from service,” then with regard to any payment or benefit that is considered “deferred compensation” under Section 409A payable on account of a “separation from service” that is required to be delayed pursuant to Section 409A(a)(2)(B) of the Code (after taking into account any applicable exceptions to such requirement), such payment or benefit shall not be paid or commence to be paid on any date prior to the first business day after the date that is six months following your “separation from service.” The first payment that can be made shall include the cumulative amount of any amounts that could not be paid during such six-month period. Notwithstanding the foregoing, a payment delayed pursuant to the preceding two sentences shall commence earlier in the event of your death prior to the end of the six-month period. Notwithstanding any provision in this Letter Agreement to the contrary, for purposes of any provision of this Letter Agreement providing for the payment of any amounts or benefits upon or following a termination of employment that are considered “deferred compensation” under Section 409A, references to your “termination of employment” (and corollary terms) with the Company shall be construed to refer to your “separation from service” (within the meaning of Treas. Reg. Section 1.409A-1(h)) with the Company.

(c) With respect to any reimbursement or in-kind benefit arrangements of the Company or under this Letter Agreement 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.

(d) Whenever a payment under this Letter Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within 30 days after termination of employment”), the actual date of payment within the specified period shall be within the sole discretion of the Company. Whenever payments under this Letter Agreement are to be made in installments, each such installment shall be deemed to be a separate payment for purposes of Section 409A.

All payments and benefits provided under Sections 10(a), 10(c) and 10(d) hereof (which includes payments provided under Sections 4(ii) and 5 hereof) shall be conditioned upon you (or if applicable, your estate, heirs or legal representatives) executing and honoring a Full and Complete Waiver, Release and Agreement substantially in the form attached hereto as Exhibit A (the “Release”). Further, if the Release is not executed, valid and irrevocable prior to the date a payment or benefit would be due or vest under Section 14(a) hereof, then such payment or benefit shall be forfeited.
