               (a) Nondisclosure of Confidential Information. You acknowledge that during the course of your performance of services as an employee of the Company and as a consultant to PASI you have had and will have access to and knowledge of certain information

that the Company considers confidential, and the release of such information to unauthorized persons would be detrimental to the Company. As a consequence, you hereby agree and acknowledge that you owe a duty to the Company not to disclose or use, and agree that during and after your performance of services for the Company and PASI you will not disclose or use, any Confidential Information (as hereinafter defined), except (i) as may be necessary or appropriate to perform services for the Company or PASI, provided your are acting in good faith and in their best interests, or (ii) with the prior written consent of the Company or PASI. You will return to the Company all Confidential Information in your possession or under your control whenever the Company shall so request, and in any event will promptly return all such Confidential Information if this Letter Agreement or the Consulting Agreement is terminated, and will not retain any copies thereof. For purposes hereof, the term “Confidential Information” shall mean any information used by or belonging or relating to the Company that is not known generally to the industry in which the Company is or may be engaged and which the Company maintains on a confidential basis, including, without limitation, any and all trade secrets and proprietary information, information relating to the Company’s business and services, customer lists and records, business processes, procedures or standards, know-how, manuals, business strategies, records, financial information, in each case whether or not reduced to writing or stored electronically, as well as any information that the Company advises you should be treated as confidential information, but shall not include (i) information which is independently obtained from a third party whose disclosure violates no duty of confidentiality to the Company, or (ii) information that is required to be disclosed by 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 to seek an appropriate protective order or confidential treatment.

               (c) Non-Solicitation and Non-Hire. During the period from the date hereof and continuing through November 10, 2011, you shall not, without the prior written consent of the Company, 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 any of its subsidiaries or affiliates whose annual compensation exceeds $100,000.

               (d) Enforcement. You acknowledge and agree that the provisions of this Section 8 are reasonable and necessary for the successful operation of the Company. You further acknowledge that if you breach any provision of this Section 8, the Company may suffer irreparable injury. It is therefore agreed that the Company shall have the right to enjoin any such breach, without posting any bond, if ordered by a court of competent jurisdiction. The existence of this right to injunctive and other equitable relief shall not limit any other rights or remedies that the Company may have at law or in equity including, without limitation, the right to

monetary and compensatory damages.

Notwithstanding the foregoing, if you are a Specified Employee (as defined under Section 409A of the Code) at the time of such Separation from Service, any payments under this Letter Agreement that are considered Deferred Compensation that would be made within the six-month period immediately following the Separation from Service shall instead be made on the first business day following the date that is six months following such Separation from Service (or upon your death, if earlier).

CONSULTING AGREEMENT

          THIS CONSULTING AGREEMENT (“Agreement”) is entered into as of the 29th day of April, 2010, by and between Platinum Administrative Services, Inc., a Delaware corporation (the “Company”) and James A. Krantz (the “Consultant”).

          WHEREAS, the Consultant is currently employed by the Company as its Executive Vice President and Chief Financial Officer;

          WHEREAS, the Consultant is a party to an employment agreement with Platinum Underwriters Holdings, Ltd., a Bermuda company (“Platinum”), dated June 1, 2007 (the “Employment Agreement”);

          WHEREAS, Platinum and the Consultant have mutually agreed that the Consultant shall retire and his employment with Platinum shall terminate effective August 10, 2010 pursuant to a letter agreement dated the date hereof (the “Letter Agreement”); and

          WHEREAS, the Company desires to retain the Consultant to perform consulting services after the termination of his employment with Platinum, and the Consultant wishes to perform such consulting services, under the terms and conditions of this Agreement.

          NOW, THEREFORE, in consideration of and in reliance upon the foregoing and the obligations and agreements contained herein, the Company and the Consultant hereby agree as follows:

          1. Consulting Services; Consulting Period.

          The Consultant agrees to be available to provide up to 250 hours of consulting services regarding accounting policy and interpretation, U.S. and Irish tax issues, financial reporting processes of the Company and its affiliates and general matters of a financial nature, at the request and direction of the President of the Company or upon his delegated authority (the “Consulting Services”) from August 11, 2010 through February 28, 2011, subject to Section 5 hereof (the “Consulting Period”). The Consultant acknowledges that he may be required by the Company to travel to New York or Bermuda up to three times during the Consulting Period to perform the Consulting Services, with each trip having a duration of not more than five (5) days.

          2. Consulting Fees.

          The Company shall pay the Consultant for the performance of the Consulting Services an amount equal to $200,000, prorated in the event of early termination pursuant to Section 5 hereof (the “Consulting Fees”), payable in three equal

installments on or prior to September 30, 2010, December 31, 2010 and February 28, 2011.

          3. Status.

          The Consultant acknowledges and agrees that his status at all times during his performance of Consulting Services hereunder shall be that of an independent contractor, and not as an employee or deemed employee of the Company or any of its affiliates. The parties hereto acknowledge and agree that the Consulting Fees paid to the Consultant during the Consulting Period shall represent fees for his services as an independent contractor, and shall therefore be paid without any deductions or withholdings taken therefrom for taxes or any other purpose. The Consultant further acknowledges that the Company makes no warranties as to any tax consequences regarding payment of such Consulting Fees, and specifically agrees that the determination of any tax liability or other consequences of the payment of such Consulting Fees is his sole and complete responsibility and that he will pay all federal, state and local taxes assessed on such payments. The Consultant acknowledges that, except as specifically provided in this Agreement or in the Letter Agreement, he will not be eligible for any benefits provided to employees of the Company or any of its affiliates.

          4. Expenses.

          The Company shall reimburse the Consultant for reasonable expenses incurred by the Consultant in the performance of the Consulting Services, provided that the Consultant obtains the prior approval of the President of the Company to the incurrence of such expense and furnishes documentation of such expenses to the Company in accordance with the Company’s expense reimbursement policy.

          5. Termination.

          This Agreement may be terminated by the Company or the Consultant at any time upon ninety (90) days’ prior written notice to the other party. This Agreement shall automatically terminate upon the death or Disability (as defined below) of the Consultant. In the event that the Consultant breaches any provision of Section 8 of the Letter Agreement, the Company may terminate this Agreement without notice to the Consultant. All rights and obligations of the parties hereunder will expire upon termination of this Agreement, except for any payment obligations of the Company for Consulting Services performed or expenses incurred pursuant to this Agreement by the Consultant prior to the effective date of the termination of this Agreement. In the event that (i) the Consultant does not execute the Full and Complete Waiver, Release and Agreement attached to Letter Agreement on August 10, 2010 (the “Release”) or thereafter revokes the Release, or (ii) the Consultant’s employment with Platinum is terminated prior to August 10, 2010, then this Agreement shall be null and void with no force or effect whatsoever. For purposes of this Section 5, “Disability” shall mean that the Consultant has been rendered unable to perform the Consulting Services by reason of any medically determined physical or mental impairment that can be expected to result in death or to last for a period of three or more consecutive months from the first date of the

Consultant’s inability to perform the Consulting Services due to the disability, as determined by the Company in its sole discretion.

          6. Section 409A.

               (a) Any payments under Section 2 hereof that are considered Deferred Compensation (within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”)), other than any payment governed by a separate award agreement, shall be made on the date that is sixty (60) days immediately following the date that the Consultant experiences a Separation from Service from the Company (as defined under Section 409A of the Code). Notwithstanding the foregoing, if the Consultant is a Specified Employee (as defined under Section 409A of the Code) at the time of such Separation from Service, any payments under this Agreement that are considered Deferred Compensation that would be made within the six-month period immediately following the Separation from Service shall instead be made on the first business day following the date that is six months following such Separation from Service (or upon the Consultant’s death, if earlier).

               (b) All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A of the Code, including, where applicable, the requirement that (i) any reimbursement shall be for expenses incurred during the Consultant’s lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year, (iii) the reimbursement of an eligible expense shall be made on or before the last day of the calendar year following the year in which the expense is incurred (or such earlier date if specified in this Agreement), and (iv) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.

               (c) To the extent applicable, it is intended that this Agreement shall comply with the provisions of Section 409A of the Code. This Agreement shall be construed and applied in a manner consistent with this intent.

          7. Miscellaneous Provisions.

               (a) Entire Agreement. This Agreement, the Letter Agreement, the Release and the Employment Agreement as modified by the Letter Agreement constitute the entire agreement among the Consultant, the Company and Platinum with respect to the subject matter hereof and, except as specifically provided herein or therein, supersede any and all prior agreements and understandings among the Consultant, the Company, Platinum or any of their subsidiaries or affiliates with respect to the subject matter hereof, whether written or oral.

Krantz, in consideration of the benefits (the “Benefits”) provided in my letter agreement with Platinum Underwriters Holdings, Ltd., dated April 29, 2010 (the “Letter Agreement”), for myself and my heirs, executors, administrators and assigns, do hereby knowingly and voluntarily release and forever discharge Platinum Underwriters Holdings, Ltd., and its subsidiaries, affiliates, predecessors, successors, agents and representatives (collectively, the “Companies”) and their respective current and former directors, officers and employees from, and covenant not to sue or proceed against any of the foregoing on the basis of, any and all claims, actions and causes of action upon or by reason of any matter arising out of my employment by the Companies and the cessation of said employment, and including, but not limited to, any alleged violation of those federal, state and local laws prohibiting employment discrimination based on age, sex, race, color, national origin, religion, disability, veteran or marital status, sexual orientation, or any other protected trait or characteristic, or retaliation for engaging in any protected activity, including, without limitation, the Age Discrimination in Employment Act of 1967 (the “ADEA”), 29 U.S.C. 621 et seq., as amended by the Older Workers Benefit Protection Act, P.L. 101-433, the Equal Pay Act of 1963, 9 U.S.C. 206 et seq., Title VII of the Civil Rights Act of 1964, as amended, 42 U.S.C. 2000e et seq., the Civil Rights Act of 1866, 42 U.S.C. 1981, the Civil Rights Act of 1991, 42 U.S.C. 1981a, the Americans with Disabilities Act, 42 U.S.C. 12101 et seq., the Rehabilitation Act of 1973, 29 U.S.C. 791 et seq., the Family and Medical Leave Act of 1993, 28 U.S.C. 2601 and 2611 et seq., the New York State and New York City Human Rights Laws, and equivalent provisions under Bermuda law (including, without limitation, the Employment Act 2000 and the Human Rights Act 1981), whether KNOWN OR UNKNOWN, fixed or contingent, which I ever had, now have, or may have, or which I, my heirs, executors, administrators or assigns hereafter can, shall or may have, from the beginning of time through the date on which I sign this Full and Complete Waiver, Release and Agreement (this “Release”), including without limitation those arising out of or related to my employment or separation from employment with the Companies (collectively the “Released Claims”). I specifically waive the benefit of any statute or rule of law which, if applied to this Release, would otherwise exclude from its binding affect any claims not now known by me to exist. This Release does not purport to waive (i) claims arising under these laws after the date of this Release or any claims for breach of this Release, (ii) claims relating to post-termination benefits provided under the terms of the Letter Agreement or (iii) any claims to post-termination benefits under the terms of any employee benefit plan of the Companies.

     I further agree, promise and covenant that, to the maximum extent permitted by law, neither I nor any person, organization, or other entity acting on my behalf has filed or will file any complaint, charge, claim or suit or cause or permit to be filed, charged or claimed, any action for damages or other relief (including injunctive, declaratory,

monetary or other relief) against the Companies or any other releasee involving any matter occurring in the past up to the date of this Release, or involving or based upon any claims, demands, causes of action, obligations, damages or liabilities which are the subject of this Release. This Release shall not affect any rights I may have under the Older Workers Benefit Protection Act to have a judicial determination of the validity of this Release and does not purport to limit any right I may have to file a charge under the ADEA or other civil rights statute or to participate in an investigation or proceeding conducted by the Equal Employment Opportunity Commission or other investigative agency. This Release does, however, waive and release any right to recover damages under the ADEA or other civil rights statute.

     I hereby warrant and represent that I have made no sale, assignment, or other transfer, or attempted sale, assignment, or other transfer, of any of the Released Claims. I fully understand and agree that:

     1. This Release is in exchange for the Benefits, to which I would otherwise not be entitled;
