The Briscoe Law Firm, PLLC, founded by a former state prosecutor and enforcement attorney for the United States Securities and Exchange Commission, and the law firm of Powers Taylor, LLP are investigating potential legal claims against the Board of Directors of Trubion Pharmaceuticals, Inc. (“TRBN” or “Company”) (NASDAQ: TRBN) related to the proposed acquisition of TRBN by Emergent BioSolutions, Inc. According to the agreement, which was announced on Thursday, August 12, 2010, each share of Trubion common stock will be converted into the right to receive an upfront payment of $1.365 per share in cash and 0.1641 shares of Emergent common stock. This transaction is valued at approximately $97 million. Additionally, Trubion shareholders will receive one Contingent Value Right ("CVR") per share, which will entitle the holder to receive cash payments based upon the achievement of certain milestones. The total potential aggregate value of the CVRs is $38.7 million over a 36-month period. The investigation relates to possible breaches of fiduciary duty and other violations of state law by the Board of Directors of TRBN for approving this transaction, whether the consideration to be received by TRBN shareholders is fair, and whether TRBN’s board of Directors acted in the shareholders’ best interests.
