This presentation is for information purposes only and does not constitute an offer or invitation to subscribe for or purchase any securities, and neither this presentation nor anything contained herein nor the fact of their distribution shall form the basis of or be relied on in connection with or act as any inducement to enter into any contract or commitment whatsoever.

Certain information included in this presentation may contain forward-looking statements including management’s assessment of future plans, operations, expectations of future production and capital expenditures. Such forward-looking information is provided for the purpose of providing information about management's current expectations and plans relating to the future. Readers are cautioned that reliance on such information may not be appropriate for other purposes, such as making investment decisions. Forward-looking information typically contains statements with words such as "anticipate", "believe", "expect", "plan", "intend", "estimate", "propose", "project" or similar words suggesting future outcomes or statements regarding an outlook. Information concerning reserves may also be deemed to be forward-looking statements as such estimates involve the implied assessment that the resources described can be economically produced. These statements are based on current expectations that involve numerous risks and uncertainties, which will cause actual results to differ from those anticipated. These risks include, but are not limited to: the risks of the oil and gas industry (e.g. operational risks relating to exploration, development and production; potential delays or changes in plans with respect to exploration or development projects or capital expenditures; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to production, costs and expenses, and health, safety and environmental risks), fluctuation in foreign currency exchange rates and commodity price fluctuation. As a consequence, actual results may differ materially from those anticipated in the forward-looking statements. Although GeoPark believes that the expectations reflected in such forward-looking information is reasonable, undue reliance should not be placed on forward-looking information because GeoPark can give no assurance that such expectations will prove to be correct. GeoPark undertakes no obligation to update forward-looking statements if circumstances or management's estimates or opinions should change, unless required by law or regulation.

In accordance with the AIM Rules, the information in this presentation has been reviewed and signed off by Carlos Murut, geologist (31 years of oil and gas experience) and Director of Development of GeoPark. Reserve and resource estimates in this presentation have been compiled by DeGolyer and MacNaughton and the Company in accordance with the 2011 Petroleum Resources Management System produced by the Society of Petroleum Engineers.
