NEW YORK–Attorney Advertising. The law firm of Wolf Haldenstein Adler Freeman & Herz LLP is investigating possible breaches of fiduciary duty by the Board of Directors of Millipore Corporation (“Millipore” or the “Company”) [NYSE:MIL] arising out of the proposed acquisition of Millipore by Merck KGaA. (“Merck”).

On Sunday, February 28, 2010, Millipore and Merck announced that Merck will acquire Millipore in an all cash offer. Under the terms of the agreement, Millipore stockholders will receive cash of $107 in exchange for each share of Millipore common stock. However, the Company may not have adequately shopped itself around before entering into this transaction and, pursuant to this proposed transaction, Merck may be underpaying for Millipore, thus unlawfully harming Millipore shareholders.

Wolf Haldenstein has been representing individual and institutional investors for many years, serving as lead counsel in numerous cases in U.S. federal and state courts. Please visit the Wolf Haldenstein website (https://www.whafh.com) for more information about the firm.
