SHAREHOLDER ALERT: Law Firm Brower Piven Announces That a Class Action Lawsuit Has Been Filed in Connection With the Optimer Pharmaceuticals, Inc. Proposed Buyout Alleging That Optimer's Directors Have Breached Their Fiduciary Duties to Shareholders -- OPT

STEVENSON, Md., Aug. 14, 2013 (GLOBE NEWSWIRE) -- The securities litigation firm of Brower Piven, A Professional Corporation, announces that a class action lawsuit has been filed in the Delaware Chancery Court on behalf of all stockholders of Optimer Pharmaceuticals, Inc. ("Optimer" or the "Company") (Nasdaq:OPTR) common stock.

According to the complaint, the proposed buyout provides for Optimer shareholders to receive $10.75 per share in cash for each share of Optimer common stock they own in addition to a Contingent Value Right ("CVR") which is expected to be publicly traded entitling the holder to receive an additional one-time cash payment of up to $5.00 for each share they own if certain net sales of DIFICID® (fidaxomicin) are achieved. The lawsuit alleges that the members of Optimer's Board of Directors have breached their fiduciary duties by agreeing to the proposed buyout for inadequate consideration and by agreeing to a series of deal protection provisions that, when viewed together, could potentially inhibit bidders from making a successful competing offer for the Company.
