NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

On December 3, 2007, ICF International (“ICF”) acquired 100 percent of the outstanding shares of Simat, Helliesen & Eichner, Inc. (SH&E). The following unaudited pro forma condensed combined financial statements have been prepared to give effect to the completed acquisition, which was accounted for as a purchase business combination in accordance with the provisions of SFAS No. 141, Business Combinations, as if the acquisition had taken place on September 30, 2007 for balance sheet purposes and January 1, 2006 and 2007 for statement of earnings purposes.

The pro forma amounts have been developed from the unaudited consolidated financial statements for the nine months ended September 30, 2007, for ICF and SH&E as well as the audited consolidated financial statements of ICF contained in its Annual Report on Form 10-K for the year ended December 31, 2006, and audited consolidated financial statements for SH&E for the year ended December 31, 2006. The assumptions, estimates and adjustments here have been made solely for the purposes of developing these combined consolidated financial statements.

In accordance with the purchase method of accounting, the assets and liabilities of SH&E were recorded at their respective fair values as of the date of acquisition. Management’s estimates of the fair value of assets acquired and liabilities assumed are based, in part, on third-party evaluations. The preliminary allocation of the purchase price was based upon a preliminary valuation and our estimates and assumptions are subject to change.

The unaudited pro forma combined consolidated financial statements are provided for illustrative purposes only and are not intended to represent the actual consolidated results of operations or the consolidated financial position of ICF had the acquisition occurred on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position. The unaudited pro forma combined consolidated financial statements should be read in conjunction with the separate historical consolidated financial statements of ICF and SH&E.

Note A. Basis of Presentation

Effective December 3, 2007, ICF acquired 100 percent of the outstanding common shares of Simat, Helliesen & Eichner, Inc. (SH&E), a privately held company that provides consulting services in the aviation industry, including network and fleet planning, cargo distribution, airline and airport privatization, mergers and acquisitions, airline safety, security and operations, technical and financial services, asset management and appraisals, corporate/business aviation, air carrier revenue management, airport concessions planning, and airport air service marketing. ICF believes that the acquisition will combine its climate-change expertise with SH&E’s expertise in the air transport industry enabling ICF to advise airlines and related suppliers on matters such as; environmental trends, greenhouse gas emissions, buying carbon offsets.

The acquisition was accounted for as a purchase in accordance with the provisions of SFAS No. 141, Business Combinations. The aggregate purchase price was approximately $51.9 million, including $51.4 million of cash and $0.5 million of transaction expenses. ICF has engaged an independent valuation firm to assist management in the allocation of the purchase price, but this allocation has not yet been finalized. The excess of the purchase price over the estimated fair value of the net tangible assets acquired was approximately $47.9 million. The independent valuation was used by ICF to allocate approximately $37.1 million to goodwill and $10.8 million to other intangible assets. The other intangible assets consist of customer-related intangibles, developed technology, and marketing-related intangibles in the amounts of $5.0 million, $3.5 million, and $2.3 million, respectively. The customer-related intangibles, developed technology, and marketing-related intangibles are being amortized over 10 years, 5 years, and 5 years, respectively. Neither the goodwill, nor the amortization of intangibles, is deductible for tax purposes. The results of operations for SH&E will be included in ICF’s statement of operations since December 3, 2007.

The preliminary allocation of assets acquired and liabilities assumed consist of the following (in thousands of dollars):

Cash	$	2,103
Accounts receivables		9,626
Other current assets		357
Customer-related intangibles		4,976
