Funded at US$4.1 Million the First Year, ICF Will Provide
Management, Analytical, and Technical Support for Implementing the
National Infrastructure Protection Plan

FAIRFAX, Va.--(BUSINESS WIRE)--March 22, 2007--ICF International (Nasdaq:ICFI) announced today that the U.S. Department of Homeland Security (DHS), Office of Infrastructure Protection, has awarded the firm, through its subsidiary ICF Incorporated, L.L.C., the National Infrastructure Protection Plan, Program Management Office (NIPP PMO) contract valued at US$22.1 million over five years and funded at $4.1 million for the first year. This work builds upon the work ICF has been doing with the NIPP PMO for the past three years. Under the contract, ICF will provide management, analytical, and technical consulting to help ensure that federal resources are applied where they offer the most benefit for mitigating risk by lowering vulnerabilities, deterring threats, and minimizing the consequences of terrorist attacks and other incidents across the nation's 17 critical infrastructure and key resources sectors.

"ICF is proud to have supported the NIPP program since its inception in January 2004 and is honored to continue this effort," said Anita Tallarico, an ICF senior vice president and recognized leader in emergency management and homeland security. "We helped DHS develop the concept for the NIPP risk management framework, prepare the outline and structure for the NIPP, and draft the first guidance for the Sector-Specific Plans (SSP). We also supported each sector in developing its SSP. This experience provides us with unique insights to support the successful implementation of the NIPP and the SSPs over the next five years."

The NIPP provides the unifying structure for the integration of critical infrastructure and key resources protection into a single national program and provides an overall framework for programs and activities that are currently underway in the various sectors, as well as new and developing protection efforts. This collaborative effort between the private and public sectors will result in the prioritization of protection initiatives and investments across sectors. ICF's role will include providing on-site support of policy development and implementation, subject matter expertise to 17 critical infrastructure and key resources sectors, outreach and engagement activities, program management support, and document production.
