As Executive Vice President, Mr. Sellier will continue his prominent leadership role in driving Argon’s growth initiatives as well as managing its corporate infrastructure, to assure the Company’s continued satisfaction of the growing demands resulting from the government’s recognition of Argon ST as a major contractor responsible for programs of national importance. This new focus will be aimed at providing the business managers of existing and newly acquired Argon ST operations with the tools and support to drive efficiencies while meeting the Company’s growth and profitability objectives. "Vic has played a significant role in our success to date,” said Dr. Terry Collins, Chairman and Chief Executive Officer, Argon ST. "During the past 10 years, he has not only driven excellence in our support organizations but also played key roles in our process improvement and customer and capability expansion initiatives. His unique and diverse skill set makes him the perfect person to assume responsibility for supporting operational efficiencies, opportunistic teaming, M&A initiatives, and ongoing infrastructure integration activities. As we work toward a second consecutive year of record bookings and backlog, I anticipate that the addition of this function to our executive management team will prove to be central to our success." "Aaron, who has been our Chief Accounting Officer since August 2006, is a natural fit for the CFO position,” continued Dr. Collins. "He is a seasoned executive who brings strong experience in leading the finance operations of both large and rapidly growing corporations. In addition, he has spent the last year gaining a thorough understanding of our business. Aaron will assume responsibility for Sarbanes-Oxley compliance, financial management, planning, and reporting as well as investor relations. I am confident that Aaron will continue to drive our focus on building value for Argon shareholders and will maintain our commitment to financial excellence established under Vic’s leadership."
