This Contract of Employment (the“Agreement”) sets out the terms and conditions of your employment with the Company at the 1st of January 2007. From this date hereof, the following terms and conditions of permanent employment shall supersede any prior terms and conditions of permanent employment between you and Allied World Assurance Company (Europe) Limited and Allied World Assurance Company Holdings, Ltd or any of its subsidiaries; it is the only legally binding agreement between the parties relating to your employment by the Company or any Group Company (as defined below).

1.	Definitions and Interpretation
1.1	In this Agreement,“Group Company”shall mean any undertaking (other than the Company) which from time to time is the Company’s subsidiary or its ultimate holding company or is a subsidiary of the Company’s ultimate holding company.

2.3	Except as otherwise provided in clause 2.1 above, no employment with a previous employer counts as part of your period of continuous employment with the Company and therefore your continuous employment begins on the Commencement Date.

3.4	You shall at all times keep the Board of Directors of the Company (the“Board”) promptly and fully informed (in writing if so requested) of your conduct of the business or affairs of the Company and any Group Company and provide such explanations of your conduct as the Board may require.

4.	Location
	Your normal place of work is 22 Billiter Street, 3rd Floor — West, London EC3M 2SS or such other location in the United Kingdom as may be required by the Company. The Company may from time to time require you to undertake any travel as may be necessary for the proper performance of your duties.

7. Salary

7.1	Your salary is £177.376 per annum payable monthly in arrears on the 25th day of each month. Payment of salary for an incomplete monthly period of service is calculated on the basis of annual salary divided by 260 (the total number of working days in a calendar year) and multiplied by the number of actual days worked in the period.
7.2	You will receive no additional payment for any overtime worked.
7.3	(a) You will be eligible for a discretionary annual bonus which will be approved by the Company, and will be based on individual and Company performance.

(b)	Bonuses, where appropriate, are only payable if the individual has not resigned and has not received or given notice of termination at the date the bonus is paid.
(c)	The Company reserves the right to change the nature of the bonus, the timing and amount of payment and the method of calculation. The Company reserves the right to discontinue the bonus scheme at any time without notice.

7.4	Your salary will be reviewed annually.
7.5	You shall not be entitled to any fees in respect of your directorship of the Company or any Group Company.
