Hagens Berman Sobol Shapiro LLP, a national investor-rights law firm, today informed investors that only 29 days remain before the lead plaintiff deadline in a lawsuit filed on their behalf against Harvest Natural Resources, Inc. (NYSE:HNR) ("HNR" or "The Company"). Investors can contact Hagens Berman Partner Reed Kathrein, who is leading the firm's investigation, by emailing HNR@hbsslaw.com or calling (510) 725-3000.

HNR investors who purchased stock in the company between May 7, 2010, and March 19, 2013, inclusive (the "class period") and suffered significant losses may also contact the firm by visiting http://www.hb-securities.com/investigations/HNR.

Investors who wish to serve as lead plaintiff in the case must move the court no later than May 21, 2013. Any member of the putative 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.

On March 19, 2013, HNR announced that due to material weaknesses in its internal controls, it would be required to revise or restate certain financial statements during 2010, 2011 and 2012. The company's stock price fell on the news.

The class-action lawsuit alleges that HNR failed to disclose material information to investors, including incorrect capitalization of certain costs and misrepresentation of certain cash flow items, among other issues.

Hagens Berman's investigation centers around what HNR and its executives knew prior to the March 19 announcement.

Hagens Berman reminds whistleblowers with inside information that rewards may be available to individuals who report information leading to a successful enforcement action by the Securities and Exchange Commission. Under the new SEC whistleblower program, whistleblowers who provide original information may receive rewards totaling up to 30 percent of any successful recovery made by the SEC.
