On March 31, 2009, ICF International, Inc. (the "Company" or "ICF"), ICF's wholly owned subsidiary ICF Consulting Group, Inc. ("ICF Consulting"), and various other subsidiaries of the Company, as co-borrowers (collectively, the "Borrowers"), modified their existing credit agreement by entering into a First Modification to the Second Amended and Restated Business Loan and Security Agreement and other Loan Documents, with Citizens Bank of Pennsylvania, as Lenders' Agent (the "Agent") and their other lenders (the "First Modification"). The following primary changes were made pursuant to the First Modification:
(i) the Agent and Lenders consented to the Borrowers' acquisition of Macro (as defined in Item 2.01 below) pursuant to the terms of the Purchase Agreement (as defined in Item 2.01 below); (ii) the Agent and Lenders have consented to the sale, in one or more offerings, of up to Two Hundred Million Dollars of capital stock of ICF, provided that the proceeds are used to pay down the credit facility; and (iii) the pricing grid was increased and certain other terms and provisions were amended.

The description of the First Modification is qualified in its entirety by the full text of the First Modification attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

On April 1, 2009, ICF and ICF Consulting completed their acquisition of Macro International Inc., a Delaware corporation ("Macro"), that was previously wholly owned by Opinion Research Corporation ("Opinion Research"), an entity wholly owned by infoGROUP Inc. ("infoGROUP"), pursuant to a Stock Purchase Agreement dated as of March 27, 2009, by and among ICF, ICF Consulting, infoGROUP and Opinion Research (the "Purchase Agreement"). Under the terms of the Purchase Agreement, ICF paid an aggregate purchase price of approximately $155 million in exchange for all of the shares of common stock of Macro, subject to a dollar-for-dollar working capital adjustment that will either increase or decrease the purchase price depending upon whether the final working capital amount is more or less than $20 million. The purchase price was financed primarily through ICF's credit line, as disclosed in Item 1.01 above. The description of the Purchase Agreement is qualified in its entirety by the full text of the Purchase Agreement, which is attached as Exhibit 2.1 hereto and incorporated herein by reference.

The Purchase Agreement has been attached to provide investors with information regarding its terms and conditions and is not intended to provide any factual information about ICF, ICF Consulting or Macro. In particular, the assertions embodied in the representations and warranties contained in the Purchase Agreement are qualified by information in the disclosure schedules provided by Macro to ICF in connection with the signing of the Purchase Agreement. Moreover, certain representations and warranties in the Purchase Agreement were used for the purpose of allocating risk between ICF and Macro, rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties in the Purchase Agreement as characterizations of the actual state of facts about ICF or Macro.

On April 1, 2009, the Company issued a press release announcing the acquisition of Macro. A copy of the release is attached hereto as Exhibit 99.1.
