    REVIEW REPORT ON INTERIM FINANCIAL STATEMENTS
    To the Legal Representative of
Pan American Energy LLC (Argentine Branch)
Av. Leandro N. Alem 1180 - 11th Floor
Buenos Aires, Argentina
    We reviewed the accompanying balance sheet of Pan American Energy LLC (Argentine Branch) as of September 30, 2008,
and the related statements of income and cash flows, notes 1 to 15 and exhibits A, B, C, D, E, F, G, H and I for the
nine-month period then ended, comparative with the same period of the prior year, and in the case of the balance sheet
and the related notes and exhibits, with the financial statements as of December 31, 2007. The preparation of these
financial statements is the responsibility of the Legal Representative of the Branch.
    We conducted our review in accordance with auditing standards generally accepted in the Republic of Argentina
applicable to the limited scope review of interim financial statements. A review of interim financial information
consists principally in applying analytical procedures to the accounting data and making inquiries of the individuals
responsible for its preparation. As a review is substantially less in scope than an audit of annual financial
statements, we do not express an opinion on the financial position of the Branch as of September 30, 2008, nor on the
results of its operations and the cash flows for the nine-month period then ended.
    The accompanying consolidated financial statements were translated into the English language from those issued in
Spanish in conformity with accounting principles and reporting practices adopted by the regulations of the National
Securities Commission ("CNV") of Argentina.
    In relation to the financial statements as of December 31, 2007, presented for comparative purposes, we issued an
unqualified opinion on March 7, 2008. In addition, on November 9, 2007, we issued an unmodified review report on the
financial statements for the nine months ended September 30, 2007, also presented for comparative purposes.
    Based on our review, we report that the financial statements as of September 30, 2008 and for the nine months then
ended referred to in the first paragraph consider all the significant facts and circumstances of which we became aware
during our review and in relation to them we have no significant observations.
    In compliance with rules and regulations in force, we report that:
    a) the financial statements comply with the provisions of the Corporations Law and the regulations on accounting
documentation of the National Securities Commission, they are transcribed in the Inventory Book and they derive from the
accounting records of the Branch maintained in the Republic of Argentina timely authorized by the Inspection Board of
Legal Entities (IGJ). Following its submission of the special report required by section 287 of Resolution 7/2005 of the
IGJ, the Branch has not received the certification from such authorities acknowledging compliance. The information
systems used to process the financial information included in the financial statements are maintained under the security
and integrity conditions based on which they were authorized;
    b) we read the reporting summary (sections "Balance sheet items", "Income statement items", and "Ratios") and the
supplementary information to the financial statements required by section 68 of the regulations of the Buenos Aires
Stock Exchange and, based on our review as far as it relates to our area of responsibility, we have no observations, and
    c) as of September 30, 2008, the accrued liability for pension contributions arising from the accounting records
amounted to $ 5,901,282, no amounts being due as of that date.

    Explanations:
    (1) The Joint Venture agreement (UTE) governing the relationships between the holders of concession states that
their participating interests in rights, obligations and interests inherent in the property including production, will
be distributed based on the depth from which production is obtained: in the deep area, the Branch has a 75% interest and
the co-holder has the remaining 25%; in the shallow area from which current total production is obtained, the Branch has
a 25% interest and the co-holder the remaining 75%; and in the area "Descubrimiento El Zanj�n", both parties hold a 50%
interest. The average interest described grants the Branch a 50% interest in the rights over the property, regardless
the percentage thereof in the concession.

     NOTE 3 - ACCOUNTING PRINCIPLES 
    3.1 Reporting currency
    In accordance with Decree 664/2003 and General Resolution No. 441/2003 of the National Securities Commission
("Comisi�n Nacional de Valores" or CNV), the Branch discontinued the application of inflation accounting as from March
1, 2003.
    From January 1, 2002 to February 28, 2003, the Branch applied the inflation accounting methodology set forth by
Technical Resolution No. 6, amended by Technical Resolutions Nos. 17 and 19 of the Argentine Federation of Professional
Councils of Economic Sciences (FACPCE) and by the Professional Council of Economic Sciences of the City of Buenos Aires
(CPCECABA), using indexes derived from the Internal Wholesale Price Index.
    3.2 Valuation and presentation principles
    a) Presentation
    The financial statements are presented in accordance with the presentation principles established by the accounting
standards generally accepted in the Republic of Argentina and pursuant to the provisions of the CNV.
    Investments to become due or to be realized in the short term (within 3 months of period end) are considered a cash
equivalent in the statement of cash flows.
    Certain reclassifications were made to the financial statements presented as comparative information to conform them
to the presentation used in this period.
    b) Participating interest in joint ventures
    The Branch is engaged in exploration and production activities in certain areas through its participation in joint
ventures with other companies. The account balances reflecting the joint ventures' assets, liabilities, income and
expenses are proportionately consolidated in these financial statements.
    c) Foreign currency
    Assets and liabilities denominated in foreign currency as listed in Exhibit F have been stated in Argentine Pesos at
the exchange rate prevailing at the end of each period. The resulting exchange gains/losses are presented in the
financial results line (provided by either assets or liabilities, as applicable) of the Statement of Income.
    d) Inventories
    Crude oil is stated at reproduction cost. Spare parts, materials and raw materials are stated at the latest
acquisition cost. Goods in transit are stated at acquisition cost plus import expenses. Advances to suppliers are valued
at the amounts actually incurred.
    The carrying value of inventories, taken as a whole and after considering the allowance for obsolescence (see Note 3
2 g), does not exceed their recoverable value.
    e) Property, plant and equipment
    Property, plant and equipment are stated at acquisition cost as indicated in Note 3.1., less the related accumulated
depreciation. The acquisition cost includes all the necessary costs incurred in order to put the assets in working
condition.
    Depreciation is calculated by applying the straight-line method over the estimated useful lives of the assets and/or
the duration of the contracts, as applicable, except for production wells, equipment and services, which are depreciated
as per the units of production method.
    The pre-operating costs of the properties in the exploration stage, except for geology and geophysics related
expenses that are charged to the Statement of Income as incurred, remain capitalized for a given period based on the
characteristics of each property, without exceeding five years considered as from the completion of the exploration
stage or, if applicable, as from production interruption, unless:
    1. it is expected that explored areas will proceed to the commercial production stage, in which case the referred
costs remain capitalized, or
    2. during the referred five year period, management estimates that commercial production will not be feasible, in
which case, the referred costs are expensed.
    For Property, plant and equipment existing as of January 6, 2002, the acquisition or construction of which resulted
in outstanding liabilities denominated in foreign currency - exchange gains/losses resulting from restating such
liabilities totaling $1,832,303,600 through July 28, 2003 were capitalized pursuant to specific accounting principles,
based on the determination of the direct or indirect ratio between the assets subject to capitalization and the
outstanding liabilities in foreign currency. The assets or group of assets eligible for the capitalization of exchange
gains/losses have remained unchanged. Such capitalization of exchange gains/losses was performed in proportion to the
balance of the original value of the referred assets not subject to depreciation. Additionally, exchange gains and
losses were capitalized up to the limit arising from the comparison between the replacement or reproduction cost of the
assets and their recoverable value.
    For the purposes of presenting the financial statements in constant currency (see Note 3.1), the capitalized
exchange gains/losses amounting to $ 1,832,303,600 are considered an anticipated inflation adjustment until such
differences are absorbed thereby. The excess of capitalized exchanges losses over the amounts in constant currency
totals $ 85,358,131 as of September 30, 2008.
    The net carrying value of property, plant and equipment, taken by group of assets of similar characteristics, does
not exceed their estimated value in use based on the information available as of the date of issuance of the financial
statements.
    f) Intangible assets
    These are pre-production geological expenditures and acquisition cost of blocks valued at restated cost as indicated
in Note 3.1, less the related accumulated amortization. Amortization is calculated as per the units of production
method.
    g) Allowances, Provisions and Accruals
    Allowances deducted from assets:
    - For bad debtors: they are determined following the detailed analysis of the credit status of each customer.
    - For obsolescence of materials: the Branch creates an allowance for those assets evidencing significant slow
movement based on a specific analysis.
    Accruals:
    - For lawsuits: they are determined considering the potential costs of those lawsuits filed against the Branch based
on the opinion of the legal counsels.
    Provisions:
    - For future compensation to personnel: they are estimated as a percentage of compensation paid, calculated in terms
of actuarial methods, and can be applied to compensate employees of the Branch who have complied with certain seniority
requirements defined by the Branch. Payments are debited from the related provision.
    - For environmental remediation: calculated on the basis of well-abandonment forecasts until the expiration of
agreements, at present values.
    h) Income tax
    The Branch applies the deferred tax method to account for income tax. Based on the referred method, the current
income tax is calculated by applying the rates prevailing as of September 30, 2008 and 2007 on taxable income; and the
future tax effect of the temporary differences in the book and tax values of assets and liabilities and the tax loss
carryforwards, if any, are recognized as deferred tax assets or liabilities. The adjustment for inflation of property,
plant and equipment is considered to be a temporary difference for deferred tax computations.
    The deferred tax assets are recognized only to the extent of their recoverability.
    i) Use of estimates
    The preparation of the financial statements in accordance with generally accepted accounting principles requires
that the Branch management makes estimates about the value of certain assets and liabilities, including contingent
liabilities, as well as the amounts informed of certain income and expenses generated during the period.
    The final amounts may differ from the estimates used in the preparation of the financial statements.
    j) Defined benefit pension plans
    The Branch implemented a pension plan for the benefit of its personnel called "Plan Puente" or "Bridge Plan". The
amount accrued upon the implementation of such plan amounts to $ 149,264,933 ($ 128,930,896 as of December 31, 2007)
presented under Other current liabilities and Other non current liabilities, out of which the amount of $ 20,689,767
accrued in the nine-month period ended September 30, 2008. Such amount is made up of $ 265,216,601 of nominal value less
$ 115,292,099 corresponding to the financial effect from the discount to present value and payments in the amount of $
659,569.
    k) Revenue recognition
    Revenue derived from the sale of hydrocarbons is recognized when the significant risks and rewards of ownership have
been transferred to the purchaser.
    The Branch uses the production method to recognize revenues from the sale of oil. In those cases where the Branch
has a shared interest with other producers, revenues are recorded upon the basis of the interest held in each joint
venture.
    In order to recognize revenues from the sale of gas, the Branch uses the sales method, whereby these revenues are
recorded on the basis of the actual volumes delivered to purchasers irrespective of whether they result form the
Branch's own output or from the output shared with other producers.
    l) Lease agreements
    The Branch leases the space occupied by its offices, which agreements are of an operating nature and, therefore, the
expenses incurred are recognized in the Statement of income to the extent they are accrued.
    The amount of the leases, broken down by maturity dates, is reported below:
    Nominal value
    Up to one year US$ 2,908,100 and $ 2,041,586
    Over one year and up to five years US$ 515,000 and $ 2,475,077
    During the nine-month period ended September 30, 2008, the Branch recognized an expense of $ 7,556,684 related to
such lease agreements presented in the line Buildings Rentals and Maintenance in Exhibit G.

     NOTE 12 - RESTRICTED ASSETS 
    In August 2007, the Branch collected a bank deposit made in its own name as collateral for a loan from a foreign
bank in fiscal year 2005. Such bank deposit amounted to US$ 1,764,705.
    In August 2007, the pledge of two generators was settled in the amount of US$ 7,483,776. Such equipment was granted
as collateral for outstanding accounts payable that were paid in June 2007.
    Therefore, there are no restricted assets as of September 30, 2008.
     NOTE 13 - INFORMATION ON LITIGATION AND OTHER SUPPLEMENTARY MATTERS 
    Lawsuits were filed against the Branch, particularly with courts in labor and commercial matters. Based on the
information available, the Branch's Management and legal advisors consider that the contingent liability that might
arise from such lawsuits would not have a material adverse effect on the financial position of the Branch or the results
of its operations.
     NOTE 14 - AGREEMENTS WITH THE PROVINCES OF CHUBUT AND SANTA CRUZ 
    The Branch entered into two investment commitments and agreements with the Argentine Provinces of Chubut (April 27,
2007) and Santa Cruz (June 25, 2007) for the extension of the term of the concession for hydrocarbon exploitation for a
ten-year period in the blocks known as Cerro Drag�n, the area of which is extended in the territory of both provinces,
and Piedra Clavada and Koluel Kaike in the province of Santa Cruz. The original term of the agreements expired between
2016 and 2017.
    These agreements provided for, among other obligations, minimum investments of US$ 2,000,000,000 in the Province of
Chubut and US$ 500,000,000 in the Province of Santa Cruz to be made before 2017.
    Furthermore, other investments of US$ 1,000,000,000 in the Province of Chubut and US$ 300,000,000 in the Province of
Santa Cruz are to be made before 2027 as a condition for PAE to be granted the operation agreements referred to below.
    The agreements also provided for a US$ 80,000,000 investment commitment for off-shore exploration, at the Branch's
own risk, by means of two joint ventures (UTEs) with the state-owned companies Petrominera (in the case of Chubut) and
Fomicruz (in the case of Santa Cruz). The potential exploration success and future business activity imply that, an
additional investment commitment in the amount of US$ 500,000,000 be required for the development of the offshore
fields.
    The creation of the UTEs referred to in the preceding paragraph is consistent with the provisions of sections 11 and
95 of the Hydrocarbon Law, which allows state-owned companies to enter into agreements and create companies,
partnerships or other associations with individuals or entities for the development of their activities.
    The operation agreements executed with state-owned companies also fall within the scope of the referred legislation,
which will be enforced as from the year 2027, subject to compliance with the investment commitments and Pan American
Energy's exploration success, in developing sufficient reserves to continue with the production of the fields of those
areas as from that year.
    Based on these agreements, during the remaining term of the concessions, the Branch agreed to pay to the respective
provinces an additional amount of 3% of the net revenues for certain items described in the agreements. The Branch will
also provide money for the development of infrastructure and the economic diversification of the Provinces of Chubut and
Santa Cruz. A number of grants will be awarded, loans given or guaranteed, job opportunities offered, and supplementary
actions will be performed by the Branch as well. In addition, Pan American Energy LLC agreed to dismiss the claims filed
against the Argentine Government with the International Centre for Settlement of Investment Disputes (ICSID), once the
agreements referred to in the previous paragraphs are finally approved. On June 18, 2008, the Company filed such
dismissal with the ICSID. On June 18, 2008, the Company filed such dismissal with the ICSID. On August 20, 2008, the
Arbitration tribunal placed on record the termination of the proceedings.
    The agreement with the province of Chubut was ratified by provincial law No. 5616 passed by the Provincial Congress
on May 24, 2007, enacted by decree No. 500/2007 and published in the Official Bulletin on May 28, 2007.
    The agreement with the province of Santa Cruz was ratified by provincial law No. 3009 issued by the Provincial
Congress on March 13, 2008, enacted by decree No. 545/2008 and published in the Official Bulletin on March 27, 2008.
     NOTE 15 - SUBSEQUENT EVENTS 
    On October 22, 2008, the Branch and YPF S.A. assigned Petrobras Energ�a S.A. 33% (16.5% each) of their interests in
the Costa Afuera Argentina "CAA-40" and "CAA-46" blocks.
    In October 2008 the Tuyunt� x-2 well in Acambuco Area, was definitively abandoned, producing a loss of $
129,715,670.
    No others events or transactions have occurred from period-end to the date of issuance of these financial statements
that would have a material effect on the financial position of the Branch or the results of its operations as of that
date.

     6. Business prospects 
    Pan American Energy LLC (Argentine Branch) is working to maintain and increase its operating efficiency in
connection with the oil and gas exploration and production, to continue increasing its share in hydrocarbon production
in Argentina, satisfying in this way the needs derived from a sustained growth rate of the country's economy as well as
to comply with its existing contractual obligations. The Branch strives to provide its personnel and contractors with
healthy and safe working conditions while preserving the environment.
    The Branch is strongly engaged with the concerns and challenges posed by the communities where it operates, by
developing different social responsibility programs (CSR).
    During this year and particularly over the last quarter, the world's economy displayed disturbing signs both in the
banking and financial sector and in the so-called real economy. The subprime mortgage crisis reached banks, mainly in
the United States and Europe, thus, giving rise to a public sense of unrest that triggered running on banks and deposit
flight. Governments of different countries were to intervene to mitigate these effects, seeking to inspire confidence
and reinstate credit-granting levels, especially restricted in emerging countries. Such anxiety also extended to the
capital markets all over the world, including the Latin American countries, and Argentina was not an exception. The
emerging countries' shares and governmental bonds evidenced a considerable fall in quoted prices.
    Additionally, there are symptoms that the real economy would be hit by the crisis, as the activity levels have
fallen, the employment rate is being adversely affected, there has been a significant decrease in the price of
commodities (including oil, which evidenced a decrease in WTI from the maximum amount of US$ 145.31 per barrel in July
2008 to US$ 60.77 in early November 2008), and also a slowdown in consumption and investment. How deep and long the
crisis would be is a question not yet answered.
    During the first nine-month period of 2008, the Branch's oil production increased by 0.3% and natural gas production
rose by 11.1% with respect to the same period of the prior fiscal year. The active investment program successfully
implemented by Pan American Energy in the last years has allowed it to double hydrocarbon production from 1999 to 2007.
    After the 2002 crisis, the country has managed to achieve high gross domestic product (GDP) growth with relatively
low inflation rates though growing recently and, a stable currency, with unemployment rates that have been significantly
reduced.
    In the first nine-month period of 2008, the GDP grew by 7.6% compared with the same period of the prior fiscal year,
which indicates that a growing trend - initiated 26 quarters ago - continues. It is estimated that the gross domestic
product will increase by 6.7% in 2008.
    In the first nine-month period of 2008, the fiscal surplus totaled 31,567 million pesos, thus disclosing a 38.5%
increase compared to the same period of the prior fiscal year. The level of foreign indebtedness as of June 30, 2008
increased with respect to the same date of the prior fiscal year and amounted to US$ 128,685 million. The country's
international reserves amounted US$ 47,121 million as of September 30, 2008, 9,9% higher than those for a year before.
    At a sector level, the increased costs in the oil industry is a matter of concern as they exceed the general rise in
prices.
    As previously informed, revenues from the exploration and production of oil and gas were affected by the amendments
to the regulations in force. In the case of oil, as from March 2002, an increasing rate of export tariffs on exports has
been applied, which has also affected the sales prices in the domestic market. On November 15, 2007, the Ministry of
Economy and Production of Argentina issued Resolution 394/07 by which export tariffs on oil and by products exports were
significantly increased for sales of oil above US$ 60.9 / barrel.
    In the case of natural gas, in January 2002, the wellhead price of natural gas was redenominated into pesos and
frozen and, afterwards, export tariffs on exports and quantitative restrictions to them were established. In April 2004,
the Secretary of Energy and the natural gas producers signed an agreement named "regularization of wellhead prices".
This agreement had a term that had expired on December 31, 2006, after which, and at the request of the related
authorities, a new agreement was signed that will be in force until December 31, 2011.
    The new agreement, approved in June 2007 by Resolution 599/07 of the Secretary of Energy, compels producers
(including the Branch) to satisfy the domestic demand up to the levels reached in 2006 plus the growth of the
residential market during the validity thereof by setting out new guidelines for price changes.
    On September 19, 2008, the Secretary of Energy issued Resolution 1070/2008 by which the wellhead price of gas was
restructured (applicable to the residential segment, CNG and power generation plants) and the residential demand of
natural gas was segmented, supplementing Resolution 599/07. Part of the increase in the price of gas shall be allocated
by gas producers to the fiduciary fund created by Law No. 26020 - aimed at meeting the liquefied petroleum gas (LPG or
Bottled Gas) needs of the poorest sectors and extending the gas networks (Resolutions 1071 and 1080 issued by the
Secretary of Energy).
    In terms of export tariffs on gas exports, Resolution No. 127/2008 is still effective. Such resolution established
that export tariffs would be equal to 100% of the highest import price of natural gas imported to Argentina applicable
each time. In the periods where LNG (liquefied natural gas) was imported to the country (June-mid September), such
amount (US$ 15.7 per million BTU on the average) was applied as an import reference price. These amounts were
established by external notes issued by the Customs Authorities. As from mid September, the applicable import price is
the Bolivian gas import price (US$ 9.03/million BTU for September and US$ 10.35/million BTU for the period
October-December).
    In the first half of 2008, the various unions gathering workers who perform tasks in the oil fields operated by the
Branch made several claims for salary increases, reclassifications, labor continuity (for UOCRA personnel), enforcement
of the collective bargaining agreements and other labor benefits. Such claims were supported by various action measures
particularly affecting the province of Santa Cruz and, as a result, the Piedra Clavada and Koluel Kaike blocks came to a
complete standstill in May and the drilling, completion and pulling activities were partially interrupted in the
province of Chubut. The Business Chambers reached agreements with the Workers Unions of Neuqu�n, both Private Oil
Workers and Hierarchy Employees. In addition, compensation agreements were signed with the Private Oil Workers Union of
Chubut, the Oil Workers Union of Santa Cruz, the Union of Hierarchy Employees of the Southern Patagonia and the
Argentine Federation of Private Oil and Gas Workers (FASP y GP). At present, the negotiations between employees and
employers' representatives for the execution and/or renewal of collective bargaining agreements with the Workers Unions
of Chubut (oil workers and hierarchy employees) and the Argentine Union Federation of Private Oil and Gas Companies
(FASP y GP) are ongoing.
    During the first nine-month period of 2008, the Branch has continued with its investment plans with a view to
expanding its business and contributing to satisfying the growing energy demand. The commitments assumed referred to in
the following paragraphs strengthen these expansion plans.
    On December 6, 2006, Law No. 26197, known as  "Hydrocarbons Short Law", was passed. This law complied with the
constitutional provision of transferring the original ownership of the natural resources contained in the subsurface
from the Federal State to the producing provinces where oil fields are located.
    Within this framework, the Branch entered into with the Argentine provinces of Chubut (04/27/2007) and Santa Cruz
(06/25/2007) two investment commitments and agreements for the extension of the term of the concession for hydrocarbon
exploitation for a ten-year period in the blocks known as Cerro Drag�n, the area of which is extended in the territory
of both provinces, and Piedra Clavada and Koluel Kaike in the province of Santa Cruz. The agreements expired between
2016 and 2017.
    These agreements provided for, among other obligations, minimum investments of US$2,000,000,000 in the Province of
Chubut and of US$ 500,000,000 in the Province of Santa Cruz to be made before 2017.
    Furthermore, other investments of US$ 1,000,000,000 in the Province of Chubut and US$ 300,000,000 in the Province of
Santa Cruz are to be made before 2027 as a condition for PAE to be granted the operation agreements referred to below.
    The agreements also provided for a US$ 80,000,000 investment commitment for off-shore exploration, at the Branch's
own risk, by means of two joint ventures (UTEs) with the state-owned companies Petrominera (in the case of Chubut) and
Fomicruz (in the case of Santa Cruz). The potential exploration success and future business activity imply that, an
additional investment commitment in the amount of US$ 500,000,000 be required for the development of the offshore
fields.
    The creation of the UTEs referred to in the preceding paragraph is consistent with the provisions of sections 11 and
95 of the Hydrocarbon Law, which allows state-owned companies to enter into agreements and create companies,
partnerships or other associations with individuals or entities for the development of their activities.
    The operation agreements executed with state-owned companies also fall within the scope of the referred legislation,
which will be enforced as from the year 2027, subject to compliance with the investment commitments and Pan American
Energy's exploration success, in developing sufficient reserves to continue with the production of the fields of those
areas as from that year.
    Based on these agreements, during the remaining term of the concessions, the Branch agreed to pay to the respective
provinces an additional amount of 3% of the net revenues for certain items described in the agreements. The Branch will
also provide money for the development of infrastructure and the economic diversification of the Provinces of Chubut and
Santa Cruz. A number of grants will be awarded, loans given or guaranteed, job opportunities offered, and supplementary
actions will be performed by the Branch as well. In addition, Pan American Energy LLC agreed to dismiss the claims filed
against the Argentine Government with the International Centre for Settlement of Investment Disputes (ICSID), once the
agreements referred to in the previous paragraphs are finally approved. On June 18, 2008, the Company filed such
dismissal with the ICSID. On June 18, 2008, the Company filed such dismissal with the ICSID. On August 20, 2008, the
Arbitration tribunal placed on record the termination of the proceedings.
    The agreement with the province of Chubut was ratified by provincial law No. 5616 passed by the Provincial Congress
on May 24, 2007, enacted by decree No. 500/2007 and published in the Official Bulletin on May 28, 2007.
    The agreement with the province of Santa Cruz was ratified by provincial law No. 3009 issued by the Provincial
Congress on March 13, 2008, enacted by decree No. 545/2008 and published in the Official Bulletin on March 27, 2008.
    The execution of these agreements proposes a new horizon to sustain the increase in production and reserves
maintained by Pan American Energy in the Golfo San Jorge basin. This new horizon and other regulatory and market
conditions will allow addressing long-term projects requiring sound investments, new technologies and teams working for
the future.
    On January 28, 2008, Pan American Energy communicated that, as a result of its permanent exploration activities in
the Cerro Drag�n block, it has been able to find new oil and natural gas reserves which were identified in the Northern
and Central areas of such block in the Province of Chibut, totaling for one hundred million equivalent oil barrels
(boe).
