Dear Kevin,

The purpose of this letter agreement (this “Letter Agreement”) is to inform you that in recognition of your contributions to the current and future value of Vangent Holding LLC and its subsidiaries (collectively, the “Vangent Companies”), including, but not limited to, Vangent Holding Corp. and Vangent, Inc., Vangent, Inc. will provide you with an enhanced retention benefit under certain terminations of employment (as described below). You are one of a select number of individuals receiving this benefit, and it is critical that you keep this Letter Agreement confidential and not discuss it with any of your colleagues.

1. Enhanced Retention. In the event that your employment with the Vangent Companies is terminated by them without Cause, or you resign from such employment for Good Reason, within the twelve (12) month period following the closing date of any “change in control”¹, Vangent, Inc. shall pay you, provided that you execute and deliver, within thirty (30) days following the date of such termination or resignation (the “Separation Date”), to Vangent, Inc. a valid release agreement substantially in the form attached as Exhibit A hereto (the “Release Agreement”) and you have not revoked such Release Agreement within such 30-day period, (i) continued payments of your annual base salary for a period of twelve (12) months following such termination or resignation,

beginning on the first payroll date that occurs forty-five (45) calendar days following the Separation Date, payable in accordance with Vangent, Inc.’s regular payroll policy and (ii) an amount equal to the pro rata portion of your bonus under the Vangent, Inc. Incentive Compensation Plan that would have been payable based on Vangent, Inc.’s projected performance as of the Separation Date through the remainder of the calendar year, payable on the first payroll date that occurs forty-five (45) calendar days following the Separation Date. In the event of such termination or resignation, group health insurance coverage (including dental and vision insurance benefits) shall continue through the end of the month following your last day of employment, and, effective with the end of coverage, you will be eligible for continued medical coverage (including dental and vision insurance benefits) under COBRA for a period of eighteen months. In the event of such termination or resignation, if you elect medical coverage under COBRA, Vangent, Inc. will pay, beginning forty-five days following the Separation Date, provided that you execute and deliver to Vangent, Inc., within thirty (30) days following the Separation Date, the Release Agreement and you have not revoked such Release Agreement within such 30-day period, the standard employer’s portion of the premium (76%), in which case you will pay the remaining portion (24%) of the premium. You will make premium payments for COBRA directly to the COBRA administrator. Information about COBRA benefits and costs will be mailed from our COBRA Administrator to your address on record within two weeks of your Separation Date. Payments that would otherwise have been owed to you prior to the 45th day after the Separation Date shall be made to you on the 45th day after the Separation Date.

For purposes of this Letter Agreement, (A) “Cause” means the occurrence of any of the following: (i) the willful engagement by you in conduct that causes material harm to any of the Vangent Companies, whether such harm is monetary or otherwise; (ii) your conviction or indictment for a felony; (iii) your willful malfeasance or willful misconduct in connection with your duties which is not cured, if curable, within thirty (30) days of your receipt of written notice; (iv) your failure to comply with a material provision of any of the Vangent Companies’ policies or procedures which is not cured, if curable, within thirty (30) days of your receipt of written notice; or (v) your breach of any covenant set forth in Section 2 of this Letter Agreement which is not cured, if curable, within thirty (30) days of your receipt of written notice; and (B) “Good Reason” means the occurrence of any of the following (i) relocation of your primary place of employment (defined as where you work at least an average of three days per week in the course of a calendar year) more than 35 miles from your primary place of employment at the time of execution of this Letter Agreement without your consent, (ii) any reduction in your current base salary or target incentive compensation, unless such reduction is part of an across-the-board reduction of senior management salaries, or (iii) a material diminution or change in your job duties or responsibilities as they existed at the time of execution of this Letter Agreement, provided, that, the Vangent Companies shall have thirty (30) days after receipt of notice from you in writing specifying the deficiency that would result in Good Reason to cure such deficiency.
