BOSTON, November 15, 2004 — Charles River Associates Incorporated (NASDAQ: CRAI), an internationally known leader in providing economic, financial, and management consulting services, today announced that it acquired Tabors Caramanis & Associates (TCA), a Cambridge, Massachusetts-based engineering and economics consulting firm specializing in policy development, business planning, productivity improvement, technical analysis, and project implementation in the energy and utility sectors.

Under the terms of the agreement, CRA acquired substantially all of the assets of the firm, comprising 15 billable consultants and current consulting projects, for a purchase price of $5.7 million, consisting of $4.7 million in cash at closing and $1.0 million in restricted shares of CRA stock.  Additional purchase consideration may be payable over the next two years if specific performance targets are met.  CRA expects the acquisition to be accretive.

“The acquisition of the TCA assets strengthens and expands our core competency in worldwide energy consulting, particularly in the electricity transmission segment,” said James C.

Richard Tabors, founder and President of TCA, said “CRA is one of the most respected companies in the consulting industry and is recognized for its expertise across a broad spectrum of functional and vertical disciplines.  Its reputation for excellence is unmatched.  Our team is excited about the opportunity to contribute to the firm’s growing Energy & Environment practice and we look forward to helping CRA’s clients achieve their operational objectives.”
