Hess has represented to us that these properties account for<br \/>\n79  percent on a net equivalent barrel basis of Hess153 net proved reserves, as of<br \/>\nDecember  31, 2009. We have reviewed information provided to us by Hess that it<br \/>\nrepresents to be Hess153 estimates of the net reserves, as of December  31, 2009,<br \/>\nfor the same properties as those which we evaluated.           Reserves included<br \/>\nherein are expressed as net reserves as represented by Hess. Gross reserves are<br \/>\ndefined as the total estimated petroleum to be produced from these properties<br \/>\nafter December 31, 2009. Net reserves are defined as that portion of the gross<br \/>\nreserves attributable to the interests owned by Hess after deducting all<br \/>\ninterests owned by others, except in Russia, where Hess owns 80  percent of a<br \/>\nconsolidated corporate joint venture. As a result, Hess net reserves include<br \/>\n20  percent of the Russian joint venture reserves not owned by Hess.           Certain<br \/>\nproperties in which Hess has an interest are subject to the terms of various<br \/>\nprofit sharing agreements. The terms of these agreements generally allow for<br \/>\nworking interest participants to be reimbursed for portions of capital costs and<br \/>\noperating expenses and to share in the profits. The reimbursements and profit<br \/>\nproceeds are converted to a barrel of oil equivalent or standard cubic foot of<br \/>\ngas equivalent by dividing by product prices to determine the &#8220;entitlement<br \/>\nreserves.&#8221; These entitlement reserves are equivalent in principle to net<br \/>\nreserves and are used to calculate an equivalent net share, termed an<br \/>\n&#8220;entitlement interest.&#8221; In this report,<\/p>\n<hr>\n<\/p>\n<table style=\"font-size: 10pt\" width=\"100%\" cellpadding=\"0\" border=\"0\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td width=\"47%\"><\/td>\n<td width=\"5%\"><\/td>\n<td width=\"47%\"><\/td>\n<\/tr>\n<tr>\n<td valign=\"top\"><\/td>\n<td><\/td>\n<td valign=\"top\">\n<p>2<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>DeGolyer and MacNaughton           Hess net reserves or interest for certain<br \/>\nproperties subject to these agreements is the entitlement based on Hess153 working<br \/>\ninterest.           Estimates of oil, condensate, NGL, and natural gas reserves<br \/>\nshould be regarded only as estimates. Such estimates are based upon information<br \/>\nthat is currently available and may change as further production history and<br \/>\nadditional information become available. Such estimates are also subject to the<br \/>\nuncertainties inherent in the application of judgmental factors in interpreting<br \/>\nsuch information.           Data used in this audit were obtained from reviews with<br \/>\nHess personnel, Hess files, from records on file with the appropriate regulatory<br \/>\nagencies, and from public sources. Additionally, this information includes data<br \/>\nsupplied by Petroleum Information\/Dwights LLC; Copyright 2009 Petroleum<br \/>\nInformation\/Dwights LLC. In the preparation of this report we have relied,<br \/>\nwithout independent verification, upon such information furnished by Hess with<br \/>\nrespect to property interests, production from such properties, costs of<br \/>\noperation and development, prices for production, agreements relating to current<br \/>\nand future operations and sale of production, and various other information and<br \/>\ndata that were accepted as represented. A field examination of the properties<br \/>\nwas not considered necessary for the purposes of this report.

DeGolyer and MacNaughton to<br \/>\nconduct the reserves audit are appropriate for purposes of this report.           In<br \/>\nour opinion, the estimated net proved reserves prepared by Hess as shown in the<br \/>\ntable above comply with the definitions and disclosure guidelines of Paragraphs<br \/>\n932-235-50-4, 932-235-50-6 through 932-235-50-9 of the Accounting Standards<br \/>\nUpdate 932-235-50, <em>Extractive Industries : Oil and Gas (Topic 932): Oil and<br \/>\nGas Reserve Estimation and Disclosures <\/em>(January  2010) of the Financial<br \/>\nAccounting Standards Board and Rules  4:10(a) (1):(32) of Regulation  S:X and<br \/>\nItems 1201, 1202(a)(1), (2), (3), (4)  and 1203 of Regulation  S-K of the<br \/>\nSecurities and Exchange Commission (SEC)  and the reserves estimation<br \/>\nmethodologies employed are appropriate.           In comparing the detailed net<br \/>\nproved reserves estimates by field prepared by us and by Hess, we have found<br \/>\ndifferences, both positive and negative. It is our opinion that the total net<br \/>\nproved reserves estimates prepared by Hess as of December  31, 2009, on the<br \/>\nproperties reviewed by us and referred to in the table above, when compared on<br \/>\nthe basis of net equivalent barrels, do not differ materially from those<br \/>\nprepared by us. <u><strong>Methodology and Procedures<\/strong><\/u><br \/>\n          Estimates of reserves were prepared by the use of standard geological and<br \/>\nengineering methods generally accepted by the petroleum industry. The method or<br \/>\ncombination of methods used in the analysis of each reservoir was tempered by<br \/>\nexperience with similar reservoirs, stage of development, quality and<br \/>\ncompleteness of basic data, and production history.           When applicable, the<br \/>\nvolumetric method was used to estimate the original oil in place (OOIP) and the<br \/>\noriginal gas in place (OGIP). Structure and isopach maps were constructed to<br \/>\nestimate reservoir volume. Electrical logs, radioactivity logs, core analyses,<br \/>\nand other available data were used to prepare these maps as well as to estimate<br \/>\nrepresentative values for porosity and water saturation. When adequate data were<br \/>\navailable and when circumstances justified, material balance and other<br \/>\nengineering methods were used to estimate OOIP or OGIP.<\/p>\n<hr>\n<\/p>\n<table style=\"font-size: 10pt\" width=\"100%\" cellpadding=\"0\" border=\"0\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td width=\"47%\"><\/td>\n<td width=\"5%\"><\/td>\n<td width=\"47%\"><\/td>\n<\/tr>\n<tr>\n<td valign=\"top\"><\/td>\n<td><\/td>\n<td valign=\"top\">\n<p>4<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>DeGolyer and MacNaughton           Estimates of ultimate recovery were obtained<br \/>\nafter applying recovery factors to OOIP or OGIP. These recovery factors were<br \/>\nbased on consideration of the type of energy inherent in the reservoirs,<br \/>\nanalyses of the fluid properties, the structural positions of the properties,<br \/>\nand the production histories. When applicable, material balance and other<br \/>\nengineering methods were used to estimate recovery factors. An analysis of<br \/>\nreservoir performance, including production rate, reservoir pressure, and<br \/>\ngas-oil ratio behavior, was used in the estimation of reserves.           For<br \/>\ndepletion-type reservoirs or those whose performance disclosed a reliable<br \/>\ndecline in producing-rate trends or other diagnostic characteristics, reserves<br \/>\nwere estimated by the application of appropriate decline curves or other<br \/>\nperformance relationships. In the analyses of production-decline curves,<br \/>\nreserves were estimated only to the limits of economic production or to the<br \/>\nlimit of the production licenses as appropriate.           Petroleum reserves<br \/>\nestimated by Hess and by us are classified as proved and are judged to be<br \/>\neconomically producible in future years from known reservoirs under existing<br \/>\neconomic and operating conditions and assuming continuation of current<br \/>\nregulatory practices using conventional production methods and equipment.<br \/>\nReserves were estimated only to the limit of economic production rates under<br \/>\nexisting economic and operating conditions using prices and costs consistent<br \/>\nwith the effective date of this report, including consideration of changes in<br \/>\nexisting prices provided only by contractual arrangements but not including<br \/>\nescalations based upon future conditions. <u><strong>Definition of<br \/>\nReserves<\/strong><\/u>           Proved reserves classifications used in this report<br \/>\nare in accordance with the reserves definitions of Rules  4:10(a) (1):(32) of<br \/>\nRegulation  S:X of the SEC of the United States. The petroleum reserves are<br \/>\nclassified as follows: <em>Proved oil and gas reserves <\/em>: Proved oil and gas<br \/>\nreserves are those quantities of oil and gas, which, by analysis of geoscience<br \/>\nand engineering data, can be estimated with reasonable certainty to be<br \/>\neconomically producible:from a given date forward, from known reservoirs, and<br \/>\nunder existing economic conditions, operating methods, and government<br \/>\nregulations:prior to the time at which contracts providing the right to operate<br \/>\nexpire, unless evidence<\/p>\n<hr>\n<\/p>\n<table style=\"font-size: 10pt\" width=\"100%\" cellpadding=\"0\" border=\"0\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td width=\"47%\"><\/td>\n<td width=\"5%\"><\/td>\n<td width=\"47%\"><\/td>\n<\/tr>\n<tr>\n<td valign=\"top\"><\/td>\n<td><\/td>\n<td valign=\"top\">\n<p>5<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>DeGolyer and MacNaughton indicates that renewal is reasonably certain,<br \/>\nregardless of whether deterministic or probabilistic methods are used for the<br \/>\nestimation.

Hess supplied appropriate differentials by field to the relevant<br \/>\nreference prices and the prices were held constant thereafter.           <em>NGL<br \/>\nPrices<\/em> Hess has represented that the NGL prices were based on a 12-month<br \/>\naverage price, calculated as the unweighted arithmetic average of the<br \/>\nfirst-day-of-the-month price for each month within the 12-month period prior to<br \/>\nthe end of the reporting period, unless prices are defined by contractual<br \/>\narrangements.

The gas prices were<br \/>\ncalculated for each property using differentials furnished by Hess and held<br \/>\nconstant thereafter.           <em>Operating Expenses and Capital Costs<\/em><br \/>\nOperating expenses and capital costs, based on information provided by Hess,<br \/>\nwere used in estimating future costs required to operate the properties. Future<br \/>\ncosts are typically based on existing costs and where appropriate adjusted to<br \/>\nreflect planned changes in operating conditions. These costs were not escalated<br \/>\nfor inflation. <u><strong>Possible Effects of Regulations <\/strong><\/u><br \/>\n          Hess153 oil and gas reserves have been estimated assuming the continuation of<br \/>\nthe current regulatory environment. Foreign oil producing countries, including<br \/>\nmembers of the Organization of Petroleum Exporting Countries (OPEC)  may impose<br \/>\nproduction quotas which limit the supply of oil that can be produced. Generally,<br \/>\nthese production quotas affect the timing of production, rather than the total<br \/>\nvolume of oil or gas reserves estimated.           Changes in the regulatory<br \/>\nenvironment by host governments may impact the operating environment and oil and<br \/>\ngas reserves estimates of industry participants. Such regulatory changes could<br \/>\ninclude increased mandatory government participation in producing contracts,<br \/>\nchanges in royalty terms, cancellation or amendment of contract rights, or<br \/>\nexpropriation or nationalization of property. While the oil and gas industry is<br \/>\nsubject to regulatory changes that could affect an industry participant153s<br \/>\nability to recover its oil and gas reserves, neither we nor Hess are aware of<br \/>\nany such governmental actions which restrict the recovery of the December  31,<br \/>\n2009, estimated oil and gas volumes.<\/p>\n<hr>\n<\/p>\n<table style=\"font-size: 10pt\" width=\"100%\" cellpadding=\"0\" border=\"0\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td width=\"47%\"><\/td>\n<td width=\"5%\"><\/td>\n<td width=\"47%\"><\/td>\n<\/tr>\n<tr>\n<td valign=\"top\"><\/td>\n<td><\/td>\n<td valign=\"top\">\n<p>9<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>DeGolyer and MacNaughton           DeGolyer and MacNaughton is an independent<br \/>\npetroleum engineering consulting firm that has been providing petroleum<br \/>\nconsulting services throughout the world for over 70  years.
