Dear
Mr. Barrow: 


        This
letter agreement confirms that CastlePoint Holdings, Ltd. a Bermuda company (the "Company"), shall employ you, and that you shall accept such employment, all on the terms
outlined below: 


        1.     Employment:
The Company shall employ you, and you shall accept employment with the Company, upon the terms and conditions set forth in this
letter agreement for the period beginning on the date the work permit described in paragraph 2 is issued to you (the "Work Permit Date") and ending as provided in
paragraph 3 (the "Employment Period"). For the intervening time that may occur between your agreed start date and when the work permit is approved, CastlePoint
Management, Inc. will employ you. 


        2.     Position &
Responsibilities: 



        (A)  Effective
on the Work Permit Date, you shall serve as Senior Vice President, Chief Accounting Officer of CastlePoint Holdings, Ltd., and that in such capacity you
shall report to the Senior Vice President and Chief Financial Officer of the Company. During the Employment Period, you shall devote substantially all of your working time and efforts to the business
and affairs of the Company. 


        (B)  You
shall use your best efforts to obtain, maintain and renew a suitable (for the purposes of your contemplated employment by the Company) work permit by the Bermuda
government authorities and any other permits required by any Bermuda government authority. The Company shall be responsible for permit fees. Your employment is subject to the requirements of the
Bermuda Ministry of Home Affairs ("Ministry"). 


        (C)  While
employed by the Company hereunder, you shall perform your duties at the offices of the Company in both Bermuda and New York City. You shall travel to such places
outside of Bermuda and New York on the business of the Company in such manner and on such occasions as the Company may from time to time reasonably require. 




        3.     Compensation:
Compensation for your services hereunder shall be at an annual base salary rate of $275,000, and an annual performance bonus
opportunity to be determined by the Board of Directors of the Company in its sole discretion. The target rate for the annual bonus shall be 30% of the base salary rate and will be prorated for 2007
based on the number of days you are employed by the Company during 2007. The base salary will be payable monthly on the 15th day of each month, two weeks in arrears and two weeks in
advance. In addition to annual base salary, you will be paid Forty Thousand Dollars ($40,000) as a Cost of Living Allowance in accordance with the previously discussed pay practice. Normal hours of
employment are 8:30 a.m. to 5:00 p.m., Monday to Friday. Your base salary has been computed to reflect that your regular duties are likely, from time to time, to require more than the
normal hours per week and you shall not be entitled to receive any additional remuneration for work outside normal hours. 


        Subject
to the approval of the Board of Directors of the Company, you are entitled to receive a one time, sign-on equity grant valued in the amount of $82,500 as of your hire
date. The vehicle of equity grant will be determined by the Board of Directors of the Company in its sole discretion; the grant may be made in stock options, restricted stock or a combination of both.
Vesting is in accordance with the Long Term Incentive Plan. Currently, the vesting is in three equal installments, over the course of 3.5 years. 










        You
are also eligible to receive annual equity opportunity to be determined by the Board of Directors of the Company in its sole discretion. The target rate for the annual equity shall
be 30% of the base salary rate. Vesting is in accordance with the Long Term Incentive Plan. Currently, the vesting is in three equal installments, over the course of 3.5 years. 


        4.     Obligations
of the Company upon Termination: 



        (A)  Termination
by the Company for other than Cause of by the Executive for Good Reason. If the Executive's employment is terminated by the
Company for any reason other than Cause or Disability or by the Executive for Good Reason, including reorganization or restructuring of the Company, 



        (i)    The
Company shall pay to the Executive, within thirty business days of the Date of Termination, any earned but unpaid Annual Base Salary; 


        (ii)   The

        (iii)  For
a period of six (6) months (one year if the Executive has been employed at least three years with CastlePoint when his employment terminates) after the Date

to those the Executive and any covered dependents were receiving immediately prior to the Notice of Termination, except for any such benefits that were waived by the Executive in writing. If the
Company arranges to provide the Executive and covered dependents with life, accident and health insurance benefits, those benefits will be reduced to the extent comparable benefits are actually
received by, or made available to, the Executive by a subsequent employer without cost during the six month period, as the case may be, following the Executive's Date of Termination. The Executive
must report to the Company any such benefits that he actually receives or are made available. In lieu of the benefits described in this subsection 4(A)(iii), the Company, in its sole discretion, may
elect to pay to the Executive a lump sum cash payment equal to the total premiums that would have been paid by the Company to provide such benefits to the Executive (determined based on the premiums
paid by the Company immediately prior to the Date of Termination). Nothing in this subsection 4(A)(iii) will affect the Executive's right to elect COBRA continuation coverage in accordance with
applicable law or extend the COBRA continuation period.
