CRA International Announces Anticipated Acquisition of Lexecon Ltd; Expected Acquisition of U.K.-Based Firm To Strengthen CRA's Global Competition Practice; Expand European Footprint.

BOSTON -- CRA International, Inc. (NASDAQ: CRAI), a globally known leader in providing economic, financial, and management consulting services, today announced that its U.K. subsidiary intends to acquire Lexecon Ltd in a cash and restricted stock transaction. CRA expects the transaction to close in May. The parties have signed an exclusive term sheet for the sale of the firm to CRA International. The transaction is subject to final negotiation and execution of definitive agreements among the parties. As part of the transaction, all of Lexecon Ltd's staff and academic associates are expected to join CRA upon closing.

Lexecon Ltd is a leading provider of competition economics in Europe. The firm has been involved in many of the high-profile cases of the past several years, including Airtours, GE/Honeywell, Tetra/Sidel, Microsoft and Oracle/Peoplesoft. Lexecon Ltd is currently advising on major matters before the European Commission, the Court of First Instance, and the competition and regulatory authorities of several Member States, as well as on major cases in South Africa, Hong Kong, and Singapore, among others. In addition to its London headquarters and an established Brussels office, Lexecon Ltd recently opened an office in Munich.

"CRA's anticipated acquisition of Lexecon Ltd will provide us with a substantially increased presence in competition economics consulting in Europe and will further expand our global reach," said James C. Burrows, President and CEO of CRA International. "This anticipated acquisition offers CRA a unique opportunity to broaden our client base and strengthen our core competencies to serve clients more effectively."

Commenting on the anticipated acquisition, Lexecon Ltd Chairman, Bill Bishop, said, "CRA is one of the foremost economic and financial consulting firms in the world, anchored by a superb U.S. practice and a growing presence in Europe and Asia. Combining Lexecon Ltd's presence in Europe, South Africa, and other regions with CRA's will create a unified worldwide practice with academic credibility and an unsurpassed talent pool and case record. We believe our acquisition by CRA is an ideal fit from both a geographic and cultural perspective."

Lexecon Ltd also has an expanding commercial litigation practice, a further growth opportunity for CRA. CRA International's capability in this area was enhanced by its April 2005 acquisition of Lee & Allen, a leading U.K.-based forensic accounting and financial dispute resolution firm. Tim Allen, senior partner of Lee & Allen, now co-head of forensic accounting at CRA, said, "With the anticipated acquisition of Lexecon Ltd, CRA will have the largest, independent, litigation support practice in Europe. We are excited about the potential acquisition, and already have identified numerous synergies."

Burrows concluded, "With the addition of Lexecon Ltd's 30-person consulting staff, academic associates, and reputation as a market leader in European competition economics, CRA will be well equipped to respond to the changing dynamics of the global litigation support marketplace."
