Harvest Natural is an independent energy company engaged in the acquisition,
development, production and disposition of oil and natural gas properties.The
Company is focused on the exploration of oil and gas fields in known
hydrocarbon basins worldwide.

The Complaint alleges that throughout the Class Period, Defendants issued a
series of materially false and misleading statements regarding the Company's
revenues and operations.Specifically, Defendants made false and/or misleading
statements and/or failed to disclose that: (1) the Company incorrectly
capitalized certain lease maintenance costs and certain internal selling,
general and administrative costs; (2) the Company improperly presented certain
cash flow items and caused certain long-lived assets to be impaired;(3) the
Company was unable to sell its interests in Petrodelta S.A. to PT Pertamina
(Persero); (4) the Company lacked adequate internal and financial controls;
and (5) as a result of the foregoing, the Company's statements were materially
false and misleading at all relevant times.As a result of Defendants'
wrongful acts and omissions, and the precipitous decline in the market value
of the Company's securities, Plaintiff and other Class members have suffered
significant losses and damages.

On February 20, 2013, the Company disclosed the termination of the Share
Purchase Agreement between PT Pertamina (Persero) and HNR Energia B.V., a
wholly-owned subsidiary of Harvest Natural.On this news, Harvest Natural
securities declined $3.71 per share or 40.5%, to close at $5.45 per share on
February 20, 2013.

On March 19, 2013, the Company disclosed that there were certain errors in its
financial statements related to, among others, the capitalization of certain
lease maintenance costs and certain internal selling, general and
administrative costs.In addition, the Company disclosed that it had
determined that a material weakness existed in its controls over the accuracy
and presentation of its accounting for certain long-lived assets.As a result,
the Company would be required to "revise and possibly restate its financial
statements for certain periods in 2010, 2011 and 2012."On this news, Harvest
Natural securities plummeted $1.79 per share or more than 32%, to close at
$3.70 per share on March 19, 2013.
