Hydrocarbon liquid volumes represent crude oil, condensate, gasoline and NGL estimated to be recovered during field separation
and plant processing and are reported in thousands (103) of stock tank cubic meters. Natural gas volumes represent expected gas sales, and are reported in million (106) standard cubic meters (at standard conditions of 15 degrees Celsius and 1 atmosphere). The volumes have not been reduced for fuel usage in the field. Based on the assumption that Argentine
royalties are a financial obligation or substantially equivalent to a production or similar tax, royalties payable to the provinces have not been deducted from the reported volumes.

Gas reserves sales volumes are based on firm and existing gas contracts, or on the reasonable expectation that any such existing gas sales contracts will be
renewed on similar terms in the future.

The tables below contain the reserves for each property.

It is our understanding that the Proved reserves estimated in this report as of September 30, 2013
constitute approximately 25.5% of YPFs Proved reserves. It is also our understanding that the Proved Undeveloped reserves estimated in this report constitute approximately 38.6% of all YPFs Proved Undeveloped reserves as of
September 30, 2013. In addition, the Manantiales Behr, Restinga Ali, Rio mayo, Sarmiento No Operada and Zona Central-Bella Vista Este fields which were audited as of December 31, 2013 represented approximately 3.5% of the YPF Proved
reserves and 1.5% of the YPF Proved Undeveloped reserves as of December 31, 2013. These proportions are on a barrel oil equivalent (BOE) basis. IHS cannot directly verify this statement as it was not requested to review YPFs other oil and
gas assets. Our study was completed on January 31, 2014.

The Chubut properties (Manantiales Behr, Restinga ali, Zona Central-Bella Vista Este and
Sarmiento No Operada) were evaluated based on the information available as at December 31, 2013. Reserves were revised for these Chubut properties to reflect the new extensions to the concession dates.

IHS audit of the YPF reserves estimates was based on decline curve analysis to extrapolate the production of existing wells or generate type curves to
estimate future production from the locations proposed by YPF. Geological information, material balance, fluid laboratory tests, reservoir simulations, field deliverability forecasts and other pertinent information was used to assess the reserves
estimates and the classification/categorization of the proposed development plans.

This audit examination was based on reserve estimates and other
information provided by YPF to IHS through December 2013 and included such tests, procedures and adjustments as were considered necessary under the circumstances to prepare the report. All questions that arose during the course of the audit process
were resolved to our satisfaction. There were no significant differences between IHS and YPF reserve estimates.

The economic tests for the
September 30, 2013 reserve volumes were based on realized crude oil, condensate, NGL and average gas sales prices as shown in the following table, as advised by YPF. A prior twelve-month first-day-of-the-month average price for West Texas
Intermediate (WTI) crude of US$96.90/BBL serves as the foundation for the oil, condensate and gasoline price. YPF is subject to extensive regulations relating to the oil and gas industry in Argentina which include specific natural gas market
regulations as well as hydrocarbon export taxes that apply until 2017 according to Law 26,217, all of which affect the realized prices of oil and other products in the domestic market. As a result, crude oil prices used to determine reserves are set
at the beginning of every month until 2013, for crude oils of

different quality produced by YPF, considering the realized prices for crude oils of such quality in the domestic market, taking into account the effects of Law 26,217. Additionally, a
significant portion of the Argentine gas market is regulated. Natural gas prices for the residential and power generation segments, as well as natural gas for vehicles, are regulated by the government. Natural gas prices for industrial consumers are
negotiated by market participants on a private basis. As a result, there are no benchmark market natural gas prices available in Argentina. IHS reviewed and accepted the prices used by YPF in estimating the reserves in Argentina.

In addition, YPF increments the crude oil, condensate and gasoline price in 2017 due to the scheduled expiration of the export retention tax mentioned above.
There is no certainty at this point that this will occur, as the export tax has been scheduled to expire several times in the recent past but extended as the deadline approached. Maintaining the current price would potentially have an impact on the
reserves estimates.

|* | YPF has not assigned any reserves to these fields
|- | -------------------------------------------------

Future
capital costs were derived from development program forecasts prepared by YPF for the fields which were summarized in economic summary tables that were provided for the reserve audit. Recent historical operating expense data were utilized as the
basis for operating cost projections and was incorporated by YPF in their economic summary tables. IHS has determined that YPF has projected sufficient capital investments and operating expenses to produce economically the projected volumes.

IHS has reviewed the estimates of total remaining recoverable hydrocarbon liquid and gas volumes at September 30, 2013 and has also reviewed the Chubut
properties (Manantiales Behr, Restinga Ali, Zona Central-Bella Vista Este and Sarmiento No Operada) based on information available as at December 31, 2013 regarding new extensions to the concession dates and associated reserve revisions.

It is IHS opinion that the estimates of total remaining recoverable hydrocarbon liquid and gas volumes at September 30, 2013, and additionally, the
Chubut properties (Manantiales Behr, Restinga Ali, Zona Central-Bella Vista Este and Sarmiento No Operada) evaluated with updated concession date information as at December 31, 2013 are, in the aggregate, reasonable and the reserves
categorization is appropriate and consistent with the definitions for reserves set out in 17-CFR Part 210 Rule 4-10(a) of Regulation S-X of the United States Securities and Exchange Commission (as set out in Appendix II). IHS concludes that the
methodologies employed by YPF in the determination of the volume estimates are appropriate and that the quality of the data relied upon, the depth and thoroughness of the estimation process is adequate.

IHS is not aware of any potential changes in regulations applicable to these fields that could affect the ability of YPF to produce the estimated reserves.

This assessment has been conducted based on IHS understanding of YPFs petroleum property rights as
represented by YPFs management. IHS is not in a position to attest to property title, financial interest relationships or encumbrances thereon for any part of the appraised properties or interests.

There are numerous uncertainties inherent in estimating reserves and resources, and in projecting future production, development expenditures, operating
expenses and cash flows. Oil and gas reserve engineering and resource assessment must be recognized as a subjective process of estimating subsurface accumulations of oil and gas that cannot be measured in an exact way. Estimates of oil and gas
reserves or resources prepared by other parties may differ, perhaps materially, from those contained within this report. The accuracy of any reserve or resource estimate is a function of the quality of the available data and of engineering and
geological interpretation. Results of drilling, testing and production that post-date the preparation of the estimates may justify revisions, some or all of which may be material. Accordingly, reserve and resource estimates are often different from
the quantities of oil and gas that are ultimately recovered, and the timing and cost of those volumes that are recovered may vary from that assumed.

For
this assignment, IHS served as independent reserve auditors. The firms officers and employees have no direct or indirect interest holdings in the properties evaluated. IHS remuneration was not in any way contingent on reported reserve
estimates. The qualifications of the technical person primarily responsible for overseeing this audit and staff members involved in the audit are included in this report.

This report has been prepared at the request of YPF regarding assets it holds in Argentina and is for inclusion in YPFs filings with the United States
Securities and Exchange Commission.

YPF will obtain IHS prior written or email approval for the use with third parties and context of the use with
third parties of any results, statements or opinions expressed by IHS to YPF, which are attributed to IHS. Such requirement of approval shall include, but not be confined to, statements or references in documents of a public or semi-public nature
such as loan agreements, prospectuses, reserve statements, websites, press releases, etc.

LIMITATIONS OF REPORT

All factual data supplied by or obtained from the files of YPF S.A.,were accepted as correct.

A field inspection was not considered necessary by IHS Global Canada Inc.

It should be understood that our audit does not constitute a complete reserves study. In the conduct of our examination, we have not independently verified
the accuracy and completeness of all the information and data furnished by your Company with respect to ownership interest or oil and gas production. We have, however, specifically identified to you the information and data upon which we relied.
Furthermore, if in the course of our examination something came to our attention that brought into question the validity or sufficiency of any of the information or data, we did not rely on that information or data until we had satisfactorily
resolved our questions or independently verified it.

This report has been prepared for the exclusive use of YPF S.A. and for the information and
assistance of its independent public accountants and financial lenders in connection with their review of, and report upon, the financial statements of your company and no part thereof should be reproduced, distributed or made available to any other

U.S. SECURITIES AND EXCHANGE COMMISSION (SEC)

MODERNIZATION OF OIL AND GAS REPORTING

As
requested by YPF S.A., the Proved Reserve definition used in this report is in accordance with the Reserve Definitions of Rules 210-4-10(a) of Regulation S-X of the Securities Exchange Commission (SEC) as amended by the SEC Modernization of
Oil and Gas Reporting  Final Rule published January 14, 2009.

SEC DEFINITIONS FOR OIL AND GAS RESERVES

Proved oil and gas reserves  Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and
engineering data, can be estimated with reasonable certainty to be economically produciblefrom a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulationsprior to the
time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the
hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.



| | (i) | The area of the reservoir considered as proved includes:
| | --- | --------------------------------------------------------

(A) The area identified by drilling
and limited by fluid contacts, if any, and

(B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged
to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.



| | (ii) | In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering, or performance data and
reliable technology establishes a lower contact with reasonable certainty.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions
of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when:
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the
operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and

(B) The project has been approved for development by all necessary parties and entities, including governmental entities.



| | (v) | Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the
period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future
conditions.

Probable oil and gas reserves  Probable reserves are those additional reserves that are less
certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered.



| | (i) | When deterministic methods are used, it is as likely as not that actual remaining quantities recovered will exceed the sum of estimated proved plus probable reserves. When probabilistic methods are used, there should be
at least a 50% probability that the actual quantities recovered will equal or exceed the proved plus probable reserves estimates.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Probable reserves may be assigned to areas of a reservoir adjacent to proved reserves where data control or interpretations of available data are less certain, even if the interpreted reservoir continuity of structure
or productivity does not meet the reasonable certainty criterion. Probable reserves may be assigned to areas that are structurally higher than the proved area if these areas are in communication with the proved reservoir.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Probable reserves estimates also include potential incremental quantities associated with a greater percentage recovery of the hydrocarbons in place than assumed for proved reserves.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | See also guidelines in paragraphs (iv) and (vi) of the definition of possible reserves.
| | ---- | ---------------------------------------------------------------------------------------

Possible oil and gas reserves  Possible reserves are those additional reserves that are less certain to be recovered than probable
reserves.



| | (i) | When deterministic methods are used, the total quantities ultimately recovered from a project have a low probability of exceeding proved plus probable plus possible reserves. When probabilistic methods are used, there
should be at least a 10% probability that the total quantities ultimately recovered will equal or exceed the proved plus probable plus possible reserves estimates.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Possible reserves may be assigned to areas of a reservoir adjacent to probable reserves where data control and interpretations of available data are progressively less certain. Frequently, this will be in areas where
geoscience and engineering data are unable to define clearly the area and vertical limits of commercial production from the reservoir by a defined project.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Possible reserves also include incremental quantities associated with a greater percentage recovery of the hydrocarbons in place than the recovery quantities assumed for probable reserves.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | The proved plus probable and proved plus probable plus possible reserves estimates must be based on reasonable alternative technical and commercial interpretations within the reservoir or subject project that are
clearly documented, including comparisons to results in successful similar projects.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | Possible reserves may be assigned where geoscience and engineering data identify directly adjacent portions of a reservoir within the same accumulation that may be separated from proved areas by faults with displacement
less than formation thickness or other geological discontinuities and that have not been penetrated by a wellbore, and the registrant believes that such adjacent portions are in communication with the known (proved) reservoir. Possible reserves may
be assigned to areas that are structurally higher or lower than the proved area if these areas are in communication with the proved reservoir.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vi) | Pursuant to paragraph (iii) of the proved oil and gas definition, where direct observation has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves
should be assigned in the structurally higher portions of the reservoir above the HKO only if the higher contact can be established with reasonable certainty through reliable technology. Portions of the reservoir that do not meet this reasonable
certainty criterion may be assigned as probable and possible oil or gas based on reservoir fluid properties and pressure gradient interpretations.

Developed oil and gas reserves  Developed oil and gas reserves are reserves of any category
that can be expected to be recovered:



| | (i) | Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------

Undeveloped oil and gas reserves Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered
from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.



| | (i) | Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that
establishes reasonable certainty of economic producibility at greater distances.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances
justify a longer time.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques
have been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in [section 210.410 (a) Definitions], or by other evidence using reliable technology establishing reasonable certainty.
