BERKELEY, Calif. -- April 23, 2013

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

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.
