Dear Martin:

The purpose of this letter agreement (the “Agreement”) is to detail the terms and conditions of your separation from Agilysys, Inc. (the “Company”). As of the close of business on the date of the Company’s 2011 Annual Meeting (the “Separation Date”), your employment with Agilysys will terminate. You will cease serving as President and Chief Executive Officer of the Company effective May 31, 2011, but will remain a Director of the Company from May 31, 2011 through the Separation Date. On the Separation Date, you will resign from all positions with the Company and its subsidiaries.

1) Severance and Benefits. Subject to paragraph 2 below, you will receive the following payments and benefits:

A schedule of these benefits is attached as Exhibit A. You expressly waive and relinquish any rights you may have to any severance benefits to which you are not entitled or vested as of the date of this Agreement under any other program, agreement, or policy.

c) Annual Incentives. You will be eligible for a FY11 annual incentive in an amount to be determined by the Compensation Committee of the Board of Directors of the Company upon final sign-off by the Company’s independent auditor of the FY11 financial results.
