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

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 Trius Therapeutics, Inc. ("Trius" or the "Company")
(Nasdaq:TSRX) common stock.

According to the complaint, the proposed buyout provides for Trius
shareholders to receive $13.50 per share in cash for each share of Trius
common stock they own in addition to a Contingent Value Right ("CVR")
entitling the holder to receive an additional one-time cash payment of up to
$2.00 for each share they own if certain commercial sales milestones are
achieved. The lawsuit alleges that the members of Trius's Board of Directors
have breached their fiduciary duties by agreeing to the proposed buyout for an
unfair price and by agreeing to lock up the proposed buyout with deal
protection provisions that deter the most likely bidders from making a
successful competing offer for the Company.

If you currently own common stock of Trius and would like to learn more about
the claims being asserted and your rights, you may email or call Brower Piven,
who will, without obligation or cost to you, attempt to answer your questions.
