FAIRFAX, Virginia, November xx, 2004 – ManTech International Corporation (Nasdaq: MANT), a leading provider of innovative technologies and solutions focused on mission-critical national security programs for the Department of Defense, the Intelligence Community, the Department of State, the Department of Justice, the Department of Homeland Security and other U.S. federal government customers announced today that Adm. David E. Jeremiah, USN (Ret) and Dr. Paul G. Stern have joined its Board of Directors. Additionally, the company announced that General Thomas C. Richards, USAF (Ret), has been elected to Chairman of its Advisory Board.

“I am very pleased to welcome Admiral David E. Jeremiah and Dr. Paul G. Stern to our Board of Directors,” said George J. Pedersen, ManTech International Corporation, Chairman and CEO, “and delighted to announce the election of General Tom Richards to Chairman of our Advisory Board.”

Admiral Jeremiah began his association with ManTech in 1994 when he was elected to our Advisory Board. He became Chairman of the Advisory Board in 2002. Because of his long association with ManTech, he knows our corporation well and, by virtue of his long, distinguished career in the Navy and industry, has an in-depth knowledge of our marketplace. “His guidance as a member and Chairman of the Advisory Board has been invaluable over the years, and we are pleased to have his expertise on our Board of Directors,” said Mr. Pedersen. During his military career, Admiral Jeremiah earned a reputation as an authority on strategic planning, financial management and the policy implications of advanced technology. From 1990 to 1994, Admiral Jeremiah served as Vice Chairman of the Joint Chiefs of Staff for Generals Powell and Shalikashvili. He has served as a Partner and President of Technology Strategies and Alliances Corporation, a strategic advisory and investment banking firm engaged primarily in the aerospace, defense, telecommunications, and electronics industries since 1994. Admiral Jeremiah also serves on the board of directors for Alliant Techsystems Inc.; Geobiotics, LLC; Todd Shipyards Corporation; and Wackenhut Services, Inc. He is on the Board of Trustees for MITRE Corporation and he serves as an Advisory Board member for Northrop Grumman Corporation. Further, Admiral Jeremiah serves on various national security panels and boards, including the President’s Foreign Intelligence Advisory Board, the Defense Policy Board and the National Reconnaissance Office Technology Advisory Group. Admiral Jeremiah earned a bachelor’s degree in Business Administration from the University of Oregon and a master’s degree in Financial Management from the George Washington University. He completed the Program for Management Development at Harvard University.

Dr. Paul Stern founded two prominent investment companies and has served as a senior executive for a number of high technology companies. “He brings a wealth of financial experience and industry knowledge. He has a clear vision for the future development of technology for the Defense and Intelligence Community and, in addition, has the financial qualifications to serve on our Audit Committee,” Mr. Pedersen said. Dr. Stern is a Partner and Co-founder of Thayer Capital Partners and Arlington Capital Partners, private investment companies. He is also the chairman of Claris Capital Partners, a Virginia-based investment bank. Prior to joining Thayer he was a Special Limited Partner with Forstmann, Little & Company from 1993 through 1995. From 1989 to 1993, Dr. Stern served as the Chairman and Chief Executive Officer of Northern Telecom Limited. In 1981 Dr. Stern joined Burroughs Corporation (later Unisys) and rose to become President and Chief Operating Officer. During his tenure, from 1981 to 1987, the company tripled its sales, increased the market value of its equity from $1.4 billion to $5 billion, and made several strategic acquisitions which led to the formation of Unisys. He came to Burroughs-Unisys from Rockwell International Corporation where he served as Corporate Vice President, and President, Commercial Electronics Operations. Before joining Rockwell, Dr. Stern served as the Chairman and Chief Executive Officer of Braun AG in Germany, and held numerous senior management positions with IBM. He currently serves on the Board of Directors of Whirlpool Corporation and Dow Chemical Company. Additionally, he is the Treasurer of the Board of Trustees of the John F.

General Thomas Richards began his association with ManTech in 1994 when he was elected to our Advisory Board where he has made significant contributions to the strategic development of the corporation. He has had a long, distinguished career in the U.S. Air Force and industry. General Richards retired in 1989 after a 33-year career with the U.S. Air Force, including serving as Deputy Commander-in-Chief of the U.S. European Command. General Richards is a member of the Federal Aviation Administration Future Planning Committee and the Air Force Senior Statesmen Program.
