Rigrodsky & Long, P.A., including former Special Assistant United States Attorney, Timothy J. MacFall, reminds shareholders of Harvest Natural Resources, Inc. (“Harvest Natural” or the “Company”) (NYSE: HNR) of an upcoming deadline involving a securities fraud class action lawsuit commenced against the Company.

A complaint was filed in the United States District Court for the Southern District of Texas on behalf of all persons or entities that purchased the common stock of Harvest Natural between May 7, 2010 and March 18, 2013, inclusive (the “Class Period”), alleging violations of the Securities Exchange Act of 1934 against the Company and certain of its officers (the “Complaint”). If you wish to serve as lead plaintiff, you must move the Court no later than May 21, 2013.

If you purchased shares of Harvest Natural during the Class Period, or purchased shares prior to the Class Period and still hold Harvest Natural, and wish to discuss this action or have any questions concerning this notice or your rights or interests, please contact Timothy J. MacFall, Esquire or Peter Allocco of Rigrodsky & Long, P.A., 825 East Gate Boulevard, Suite 300, Garden City, NY at (888) 969-4242, by e-mail to info@rigrodskylong.com, or at: http://www.rigrodskylong.com/investigations/harvest-natural-resources-inc-hnr.

A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation. In order to be appointed lead plaintiff, the Court must determine that the class member’s claim is typical of the claims of other class members, and that the class member will adequately represent the class. Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff. Any member of the proposed class may move the court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.

While Rigrodsky & Long, P.A. did not file the Complaint in this matter, the firm, with offices in Wilmington, Delaware and Garden City, New York, regularly litigates securities class, derivative and direct actions, shareholder rights litigation and corporate governance litigation, including claims for breach of fiduciary duty and proxy violations in the Delaware Court of Chancery and in state and federal courts throughout the United States.
