Legal Framework Ley Orgánica de la Administración Pública Federal (Article 33, XX) The energy ministry (SENER) will register and publish, based on the information of CNH, the reserves, according to the studies, assessment, quantification, and certifications. Ley de la CNH (Article 4, II y X) Some of CNH s attributions: To participate with SENER in determining the policy for reserves replacement. To perform studies of evaluation, quantification and verification of reserves. Reglamento de la Ley Reglamentaria del Artículo 27 Constitucional en el Ramo del Petróleo (Article 10) The final reports by independent certifying parties must be OK ed by CNH. Evaluation reports by PEMEX and quantification must be approved by CNH. Based on information from the CNH, SENER will register and publish the country's hydrocarbon reserves. 6

Reserves Guidelines Obtain Technical elements needed to perform studies of evaluation, quantification and verification. Establish Calendar of procedures, steps and requirements that Pemex and independent third parties must observe before submitting their reports. Assess Consistency between Pemex assessments and independent third parties (less than 10% at the regional level). Document Professional profile and independence of third parties.

Reserves Guidelines 12

Reserves Resolution 2010 Approved the reports of assessment and quantification of reserves of Pemex for the 1P, 2P and 3P categories of the Northeastern Marine Region, Southwestern Marine Region and Southern Region. Approved the 1P reserves of the Northern Region. The differences between Pemex s figures and the certifying company s figures were greater than 10% for the 2P and 3P categories for the Northern Region. A specific review procedure was established. 14

Reserves Resolution 2011 Approved the reports of assessment and quantification of reserves of Pemex for the 1P, 2P and 3P categories of the Northeastern Marine Region, Southwestern Marine Region and Southern Region. Approved the 1P reserves of the Northern Region. The differences between Pemex s figures and the certifying company s figures were greater than 10% for the 2P and 3P categories for the Northern Region. The Commission concluded that the differences were contingent resources in the Chicontepec Asset. 16

The Commission concluded that the differences were contingent resources in the Chicontepec Asset. 17

Reserves Resolution 2012 The 1P reserves were also sanctioned at Administrative Unit (Asset) level. Mexico s oil reserves as of January 1st 2012, were sanctioned by the CNH. For the first time, the 1P reserves were sanctioned at the Administrative Unit level. The hydrocarbon volumes were approved for all the Administrative Units. Also, for the first time the CNH approved the 2P and 3P reserves of the four administrative Regions including Chicontepec (contain several recommendations issued by CNH and SENER). The Administrative Unit Abkatun Pol Chuc required further analysis, but finally approved

Analysis level Analysis level Oil Gas BOE The analysis will focus on the identification and assessment of the differences between the figures provided by the independent third parties and Pemex, for all categories, and these products: oil, gas and crude oil equivalent. Derived from: Resolution of the CNH Governing Body. Attention to the observations of external auditors for the public sector. Consultations with operating companies, certifiers, consultants and regulators. 23

Criteria of the review process Criteria of the review process Differences (percentage) Region Level Administrative Unit Level The analysis will focus on the identification and assessment of the differences between the figures provided by independent third parties and Pemex < 10% (first criterion). For 1P reserves, the anaylisis will be at the level of Administrative Unit. The analysis level for 2P and 3P reserves will be Region, For the following products: oil, gas, crude oil equivalent. CNH will consider the impact of the net value of the differences between Pemex and the certifier compared with regional and national total. (Second criterion). 24

Conclusions For the first time in the history of Mexico, there s an independent agency that reviews the process of Pemex and the certifying companies. For the first time in history, Mexico s reserves numbers are within 10% of those calculated by third parties. Current guidelines are the result of improvements to the previous guidelines. Collaboration between CNH, Sener and Pemex allowed identification of the elements that needed to be reviewed. These improvements allow us to have higher (reasonable) certainty in the hydrocarbon reserves. The new guidelines contain elements that are clearer and that are fully accepted by all the entities involved in this process: CNH, Pemex and SENER. The new guidelines allow better analyses and avoid unnecessary revision processes. 34
