     III. Base Salary.

     Your annual base salary (“Base Salary”) will be $575,000, payable in accordance with Polaris’ customary payroll policy, less all applicable withholdings and deductions. Your Base Salary will next be reviewed by the Compensation Committee of the Board of Directors (“Compensation Committee”) in January of 2010. Thereafter it will be reviewed annually by the Compensation Committee. As a result of each review your Base Salary may, at the discretion of the Board of Directors, be increased.

     IV. Annual Cash Incentive Compensation.

          You will participate in Polaris’ Senior Executive Annual Incentive Compensation Plan or, alternatively, any performance-based annual incentive plan that Polaris may adopt for one or more of its senior officers in lieu of its Senior Executive Annual Incentive Compensation Plan (the “Annual Incentive Plan”).

You will be eligible to receive a target Annual Bonus under the Annual Incentive Plan equal to 100 percent of your Base Salary (the “Bonus Target Amount”) subject to the performance criteria established by the Compensation Committee under the Annual Incentive Plan. The maximum Annual Bonus that you will be eligible to receive under the Annual Incentive Plan will be equal to 150 percent of your Base Salary. For the year ending December 31, 2008, you will be awarded a payment under the Annual Incentive Plan in an amount of no less than the Bonus Target Amount pro-rated for the number of months during 2008 that you are employed by Polaris.

     V. Long Term Incentive Plan.

          You will participate in Polaris’ Long Term Incentive Plan, or alternatively, any long term performance based incentive plan that Polaris may adopt for one or more of its senior officers in lieu of the Long Term Incentive Plan (the “LTIP”). The Compensation Committee will determine, in accordance with the LTIP, the actual amount of any long term incentive payment to be awarded to you for each three-year performance cycle under the LTIP. You will be eligible to receive a target long term incentive payment equal to 100 percent of your Base Salary (the “LTIP Target Amount”) subject to the performance criteria established by the Compensation Committee under the LTIP.
