(c) On December 14, 2011, NCI, Inc. (“NCI” or the “Company”) issued a press release to announce that Mr. Lucas J. Narel, age 37, is joining the Company and will assume the position of the Executive Vice President, Chief Financial Officer and Treasurer beginning on January 1, 2012. Mr. Narel previously served as vice president of finance for CGI Federal, a $1.2 billion government information technology contractor and wholly-owned subsidiary of CGI Group, overseeing accounting, budgeting and financial operations, as well as the financial integration of CGI’s $1.1 billion acquisition of Stanley, Inc. in August 2010. Prior to CGI’s acquisition of Stanley, Mr. Narel was vice president and corporate controller for Stanley where he played key roles in its initial public offering in 2006, the company’s transition to a public company, and provided executive leadership on a number of strategic transactions and financings which supported growth that more than tripled the size of the company since going public. Mr. Narel holds a B.S. degree in Accounting from Virginia Polytechnic Institute and State University and a Masters degree from American University.

As is the case with the Company’s other executive officers, Mr. Narel will not be subject to an employment agreement, although he will enter into an Executive Change in Control and Severance Agreement, which will provide for certain payments to be made upon a change in control and termination. Mr. Narel will initially receive a salary of $280,000 per year and will be eligible for an annual cash bonus for 2012 performance, the amount of which will be dependent upon the achievement of certain target performance goals to be established by the Company’s Compensation Committee. The bonus amount at target will be 75% of base salary ($210,000) for 2012.

Mr. Narel will receive an option award of 30,000 options to purchase NCI stock at the fair market value on the date of grant and a grant of 20,000 restricted shares of stock. The grants will be issued in accordance with our policy. Both grants vest in four equal annual installments beginning on the date of grant.
