</B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">The following information is presented in order to comply with the requirements of Resolution 541/08, <I>&#147;Disclosures about Oil and Gas
Reserves&#148; </I>of the National Securities Commission <I>(&#147;Comisi&oacute;n Nacional de Valores&#148;). </I> </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B>Oil and gas reserves
</B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Proved oil and gas reserves are the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering available
data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made. Prices include consideration of changes
in existing prices provided by contractual arrangements, but not on increases based upon future conditions. Proved developed oil and gas reserves are reserves that can reasonably be expected to be recovered through existing wells with existing
equipment and operating methods. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Estimates of reserves were prepared using standard geological and engineering methods generally accepted by the petroleum
industry and in accordance with the rules and regulations of the SEC effective as of December&nbsp;31, 2008. The choice of method or combination of methods employed in the analysis of each reservoir was determined by experience in the area, stage of
development, quality and completeness of basic data, and production history. There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures,
including many factors beyond the control of the producer. Reserve engineering is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner and the accuracy of any reserve
estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. In addition, results of drilling, testing and production subsequent to the date of an estimate may justify revision of such
estimate. Accordingly, reserve estimates are often different from the quantities of crude oil and natural gas that are ultimately recovered. The meaningfulness of such estimates is highly dependent upon the accuracy of the assumption upon which they
were based. The reserve estimates were subjected to economic tests to determine economic limits. The reserves in Argentina are stated prior to the payment of any royalties to the provinces in which the reserves are located. Consequently, royalties
are given effect in such economic tests as operating costs in Argentina. The estimates may change as a result of numerous factors including, but not limited to, additional development activity, evolving production history, and continued reassessment
of the viability of production under varying economic conditions. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">The following tables reflect the estimated reserves of crude oil, condensate, natural
gas liquids and natural gas as of December&nbsp;31, 2008, 2007 and 2006 and the changes therein: </FONT></P>
