         On August 30, 2004, Harvest Natural Resources, Inc. (the "Company")

effective September 1, 2004. The Employment Agreement provides for the payment
to Mr. Edmiston of a base salary of $300,000 a year and a $50,000 signing bonus.
Mr. Edmiston will be eligible for annual bonus awards at the discretion of the
Company's Board of Directors. Mr. Edmiston was also granted 20,000 shares of
restricted stock and a stock option covering 100,000 shares. The Employment
Agreement has an initial term, which is automatically extended for one year upon
each anniversary, unless a one year notice not to extend is given by the
executive or the Company. The initial term of the Employment Agreement is
through May 31, 2007.

         The Employment Agreement provides that if the Mr. Edmiston is
terminated without cause or notice, or resigns for good reason, then the Company
will pay two years base salary. In addition, the remaining restriction period of
any restricted stock awards will lapse, and any outstanding stock options shall
vest and remain exercisable for the shorter of 12 months or the remaining term.
Under the Employment Agreement, resignation for good reason includes that
someone other than Mr. Edmiston or the current Chief Executive Officer of the
Company is appointed Chief Executive Officer of the Company after August 31,
2005 and before August 31, 2006.

         The Employment Agreement for Mr. Edmiston also provides that in the
event of a change of control of the Company and the termination of his
employment without cause or for good reason within 240 days before or 730 days
after a change of control, he will be entitled to the same benefits as for a
termination without cause or resignation for good reason, and is also entitled
to an amount equal to two times any annual bonus(the higher of the highest bonus
over the three prior years or the target bonus), continuation of accident, life,
disability, dental and health benefits for two years, and reimbursement for
taxes (including any excise tax) on the above amounts.

         In consideration of the benefits provided under the Employment
Agreement, Mr. Edmiston agrees to protect the Company's trade secrets and,
during the period of employment and for two years thereafter, to not disclose
proprietary and confidential information or to compete with the Company in areas
in Russia and Venezuela where the Company is doing business or has prospective
interests.
