Biographical information about Mr. Asbury is as follows:

Prior to joining CACI, Mr. Asbury, age 58, was employed by Lockheed Martin from 1984 to 2011, where he oversaw Lockheed Martin’s Technical Operations, Mission Services and Civil businesses. Lockheed Martin is not a parent, subsidiary or other affiliate of the Company.

Mr. Asbury spent nearly 30 years at Lockheed Martin in a number of leadership roles. Prior to joining CACI, he was President of the Civil Business Group, and that unit saw $3.7 billion in sales in 2009 and more than $6 billion in new contract orders. While at Mission Services, Asbury delivered double digit sales and achieved a 75 percent new business win rate. After Lockheed he joined ASRC Federal, where as president and chief executive officer, he was responsible for setting the strategic direction of the company’s Federal enterprise and driving growth and development for all of its subsidiaries.

There was no arrangement or understanding pursuant to which he was selected as an officer of the Company. There are no family relationships between Mr. Asbury and any director or executive officer of the Company, or any person chosen by the Company to become a director or executive officer. There are no related party transactions of the kind described in Item 404(a) of Regulation S-K in which Mr. Asbury was a participant.

The Board of Directors also approved an Employment Agreement in connection with Mr. Asbury’s role as President and Chief Executive Officer of the Company. Under the terms of the agreement, Mr. Asbury will receive a base salary of $750,000 and an incentive bonus target, which is based upon achievement of Company profitability, revenue, and other operational goals, of $1,000,000. Mr. Asbury will also receive a long-term incentive stock grant in the form of 300,000 performance-based restricted stock units that vest in three equal annual increments beginning on the third anniversary of his employment. Also under the agreement, assuming a termination event (termination by CACI without cause as defined in the agreement or a resignation by Mr. Asbury for “good reason” as defined in the agreement) occurs, Mr. Asbury will receive a severance payment equal to 24 months base salary, continued participation in CACI’s health care coverage for a one-year period, and any bonus amounts due to him that would otherwise be payable under the annual incentive program for the fiscal year of termination.
