Copyright © ENEOS Holdings, Inc. All Rights Reserved. 44 Oil and Natural Gas E&P Segment The ENEOS Group’s Reserve Standards

The ENEOS Group’s criteria for evaluating reserves conforms to the PRMS (Petroleum Resources Management System) Standards drafted by the SPE (Society of Petroleum Engineers), WPC (World Petroleum Congress), AAPG (American Association of Petroleum Geologists), and SPEE (Society of Petroleum Evaluation Engineers). The ENEOS Group’s reported reserves are in line with reserves as defined by PRMS Standards. The degree of certainty of the reserve values is categorized, in order, as either Proved, Probable, or Possible. Following trends common at other industry firms, the ENEOS Group has used Proved and Probable reserves to arrive at its total reserves.

Definition of Proved Reserves Reserves judged to have a high level of certainty from analysis of geoscience and production/ data, based on economic conditions, operational methods and laws and regulations assumed by the ENEOS Group in light of discovered reservoirs—there is at least a 90% probability that actual recovered volume will equal or exceed estimates of oil and natural gas deposits reasonably evaluated as commercially recoverable.

Definition of Probable Reserves There is at least a 50% probability that additional oil and natural gas reserves will equal or exceed actual recovered volume of the total of estimated proved and probable reserves. While these additional reserves are evaluated in the same manner as proved reserves, the probability of recoverability of probable reserves is lower than proved reserves, but higher than possible reserves.

Note: For 2010 year-end, several types of agreement were made depending on negotiating parties, contractual period, etc.

Cost of copper concentrate The price of copper concentrate, which custom smelters pay to mining companies, is the LME copper cathode price less TC/RC, which is smelting and refining margins. TC/RC under long-term contracts is normally determined through annual negotiation between copper smelters and mining companies.

Copper cathode sales price The actual sales price of copper cathode produced by copper smelters is the LME price plus sales premium, which is established by reference to various factors, including importation costs and quality.
