Robbins Umeda LLP has commenced an investigation into possible breaches of fiduciary duty and other violations of state law by members of the Board of Directors ("Board") of BMP Sunstone Group ("BMP" or the "Company") (NASDAQ: BJGP) in connection with their efforts to sell BMP to Sanofi-aventis (NYSE: SNY). If the transaction is completed, BMP shareholders will receive $10.00 in cash for each share of BMP common stock they hold.

Robbins Umeda LLP's investigation concerns whether, in entering into the definitive merger agreement, BMP's Board undertook a fair process to obtain fair consideration for all shareholders of BMP. Specifically, our investigation concerns whether members of the Company's Board breached their fiduciary duties to BMP shareholders by failing to adequately shop the Company before entering into the transaction with Sanofi-aventis.

If you are a shareholder of BMP, plan to continue to hold your shares, and would like more information about your rights as a shareholder, please contact attorney Gregory E. Del Gaizo at 800-350-6003 or by e-mail at info@robbinsumeda.com.
