FAIRFAX, VA, December 5, 2006 – ICF International (Nasdaq: ICFI) announced today that it received its second task order, valued at US$3.2 million under ICF’s five-year, multiple award, indefinite quantity contract for Project Development and Management Services, and Environmental and Engineering Consulting from the Millennium Challenge Corporation (MCC), the U.S. government-owned corporation responsible for the stewardship of the Millennium Challenge Account (MCA). The MCA was established by the U.S. Government for providing developmental assistance to reduce poverty by significantly increasing the economic growth trajectory of recipient countries. Under the second task order, the ICF team will provide engineering and consulting advisory services during the implementation of two of the projects that make up the compact between the MCC and the government of Armenia: a rural roads rehabilitation project and an irrigated agriculture project.

"We are pleased at the opportunity to work with MCC on this task order, striving to reduce rural poverty in Armenia by improving the country’s agricultural sector," says Sergio Ostria, a senior vice president with ICF. “The program focuses on promoting the sustainable economic growth that in turn reduces poverty through investments in areas such as agriculture, education, private sector development, and capacity building.”

"The ICF team is proud to be a part of such a meaningful program, and we will work diligently to help MCC monitor and evaluate the implementation of these projects," says Walt Palmer, ICF’s program manager of the firm’s IDIQ contract with MCC.

ICF was formerly awarded its first task order, valued at US$897,345 on September 28, 2006. Under the first task order, the ICF team is assisting MCC in overseeing the implementation of a US$40 million north-south gas pipeline rehabilitation project in the Republic of Georgia.
