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 BMP Sunstone Corporation (?BMP Sunstone? or ?BJGP) (NASDAQ: BJGP) related to the acquisition of BMP Sunstone by Sanofi-aventis.

Under the definitive merger agreement, which was announced on October 28, 2010, BMP Sunstone shareholders will only receive $10.00 in cash for each share of BMP Sunstone/BJGP common stock they hold. The transaction is valued at $520.6 million on a fully diluted share basis, and the acquisition is structured to include a merger of BMP Sunstone with a wholly owned subsidiary of Sanofi-aventis.

Based on the lack of an appreciable premium to shareholders, BMP Sunstone's historical stock price, and other factors, the proposed transaction may undervalue BMP Sunstone/BJGP shares and not be fair to BMP Sunstone shareholders. The investigation relates to possible breaches of fiduciary duty and other violations of state law by the Board of Directors of BMP Sunstone for approving this transaction and whether BMP Sunstone's Board of Directors acted in the shareholders' best interests.

If you currently own shares of BMP Sunstone/BJGP and would like additional information regarding this investigation, or if you have information regarding the allegations involving this transaction, please contact Patrick Powers at Powers Taylor, LLP, toll free (877) 728-9607, via e-mail at patrick@powerstaylor.com, or Willie Briscoe at The Briscoe Law Firm, PLLC toll free (877) 397-5991, or via email at WBriscoe@TheBriscoeLawFirm.com.
