BP Shareholders File Lawsuit Over Gulf Oil Spill

Safety lapses, accidents and disasters not new to company, complaint says

NEW YORK, June 10, 2010 - Citing the company's history of safety lapses, cost cutting, and
workplace disasters, shareholders who purchased stock in BP have filed a
class-action lawsuit based on claims that the company mislead investors prior
to the Deepwater Horizon oil spill in the Gulf of Mexico. The suit, filed in
the U.S. District Court for the Eastern District of Louisiana, seeks to
represent not only American investors, but also people around the world who
bought shares in United Kingdom-based BP.

Zwerling, Schachter & Zwerling, LLP filed the class-action lawsuit on
behalf of individuals or entities that purchased ordinary shares and/or
American Depository Receipts in BP p.l.c. during a period beginning February
27, 2008, through May 12, 2010, (the "Class Period"). BP's ADRs and ordinary
shares are actively traded on the New York Stock Exchange (NYSE: BP) and the
London Stock Exchange (London Stock Exchange: BP.L), respectively.

The lawsuit notes BP's prior statements about its Gulf operations being a
primary economic driver, and the company's assertions that it had the
technology to safely conduct the operations. But nearly a month after the
catastrophic explosion at the Deepwater Horizon, BP's Chief Executive Officer
Anthony B. Hayward admitted that BP did not have the technology available to
stop the Gulf leak.

The lawsuit chronicles BP's long history of spills, fires and explosions
at its facilities, including a 2005 explosion in Texas City, Texas, that
killed 15 people, and a 2006 oil leak in its Prudhoe Bay, Alaska, operations
pipeline. In the Alaska case, Zwerling, Schachter & Zwerling served as lead
counsel for securities plaintiffs who brought suit against BP, and secured a
multimillion-dollar settlement on their behalf.

In the current case, shareholders claim BP violated the Securities
Exchange Act of 1934 by issuing false and misleading statements about safety,
technology, inspections and precautions at its offshore oil facilities. At
the time of the latest disaster, BP shares were trading at nearly US$60, but
since have lost nearly half their value.

If you purchased or otherwise acquired the ordinary shares and/or ADRs of
BP during the Class Period, you may apply to serve as lead plaintiff. The
lead plaintiff is responsible for overseeing the prosecution of the action
and ensuring that the interests of the class are protected. Should you desire
to be lead plaintiff, you may apply to be appointed through Zwerling,
Schachter & Zwerling, as counsel. The deadline for seeking to become a lead
plaintiff is July 20, 2010.
