2.1 Generation

2.1.1. SEE Resolution No. 19-E/17 –New Remuneration Scheme for generation

On February 2, 2017, the SEE issued Resolution No. 19-E/17 (the "Resolution"), which replaces the remuneration scheme set forth by Resolution No. 22/16 (update of the remuneration scheme implemented by Res. No. 95/13 and previously updated by Res. No. 529/14 and Res. No. 482/15) and establishes guidelines for the remuneration to generation plants as from the commercial transaction corresponding to February 1, 2017.

2.1.1.1 Remuneration for Available Power Capacity

Thermal Power Generators

The Resolution provides for a minimum remuneration for power capacity based on technology and scale, and allows generating, co-generating and self-generating agents owning conventional thermal power stations to offer Guaranteed Availability Commitments for the energy and power capacity generated by their units not committed under the Energía Plus service modality or under the WEM Supply Agreement pursuant to Resolution No. 220/07.

(in millions of Argentine Pesos (“$”) – unless otherwise stated)

NOTE 2:(Continuation)

Power capacity availability is determined independently of the reservoir level, the contributions made, or the expenses incurred. Furthermore, in the case of pumping hydroelectric power plants, the following is considered to calculate availability: i) the operation as turbine at all hours within the period, and ii) the availability as pump at off-peak hours every day and on non-business days.

The base remuneration is determined by the actual power capacity plus that under programmed and/or agreed maintenance:

Technology/Scale	Base Price (U$S/MW- month)
Medium HI Capacity > 120 ≤ 300 MW	3,000
Small HI Capacity > 50 ≤ 120 MW	4,500
Large Pumped HI Capacity > 120 ≤ 300 MW	2,000

Similarly to the provisions of Resolution No. 22/16, in the case of hydroelectric power plants maintaining control structures on river courses and not having an associated power plant, a 1.20 factor will be applied to the plant at the headwaters.

The additional remuneration applies to power plants of any scale for their actual availability and based on the applicable period:

Type of Power Plant	Period	Additional Price (U$S/MW- month)
Conventional	May 17 – Oct. 17	500
Conventional	Nov. 17 onwards	1,000
Pumped	May 17 – Oct. 17	-
Pumped	Nov. 17 onwards	500

As from November 2017, the allocation and collection of 50% of the additional remuneration will be conditional upon the generator: i) taking out insurance, to CAMMESA’s satisfaction, to cover for major incidents on critical equipment; and ii) the progressive updating of the plant's control systems pursuant to an investment plan to be submitted based on criteria to be defined by the SEE.

Other Technologies

The remuneration is made up of a base price and an additional price associated with the availability of the installed equipment with an operating permanence longer than 12 months as from the beginning of the Summer Seasonal Programming.

Medium HI Capacity > 120 ≤ 300 MW	3.5	1.4
Small HI Capacity > 50 ≤ 120 MW	3.5	1.4
Large Pumped HI Capacity > 120 ≤ 300 MW	3.5	1.4

2.1.1.3 Additional Remuneration for Efficiency

The Resolution keeps in force the additional remuneration for efficiency created by Resolution No. 482/15.

2.1.1.4 Additional Remuneration for Low-Use Thermal Generators

The Resolution provides for an additional remuneration for low-use thermal generators having frequent startups based on the monthly generated energy for a price of U$S 2.6/MWh multiplied by the usage/startup factor.

The usage factor is based on the Rated Power Use Factor recorded during the last rolling year, which will have a 0.5 value for thermal units with a usage factor lower than 30% and a 1.0 value for units with a usage factor lower than 15%. In all other cases, the factor will equal 0.0.

The startup factor is established based on startups recorded during the last rolling year for issues associated with the economic dispatch made by CAMMESA. It will have a 0.0 value for units with up to 74 startups, a 0.1 value for units recording between 75 and 149 startups, and a 0.2 value for units recording more than 150 startups. In all other cases, the factor will equal 0.

2.1.1.5 Repayment of Overhaul Financing (applicable to thermal and hydroelectric generators)

The Resolution abrogates the Maintenance Remuneration and provides that, as regards the repayment of outstanding loans applicable to thermal and hydroelectric generators, credits already accrued and/or committed to the cancellation of such maintenance works will be applied first. The balance will be repaid by discounting U$S 1/MWh for the energy generated until the total cancellation of the financing.

2.1.2. Recategorization of hydroelectric power plants of subsidiary HINISA:

On April 10, 2017, the SEE provided for the recategorization of the Nihuil I, Nihuil II and Nihuil III plants as small-scale plants for the application of the effective remuneration scheme. Thus, the SEE rectified the incorrect categorization initially assigned to these plants in line with the repeated claims lodged by the Company since April 25, 2013.

Pursuant to the terms of the SEE's instruction to CAMMESA, the recategorization is effective as from April 2017.

The impact of this recategorization represents a 50% increase in the base remuneration for power capacity, which thus rises from U$S 3,000 - month to U$S 4,500 -month.

2.1.3. 2014 Agreement for the Increase of Thermal Generation Availability

On July 14, 2017, CTLL entered into with CAMMESA the WEM Supply Agreement under SE Resolution No. 220/07 for the new 105 MW high-efficiency gas turbine, retroactively as of July 15, 2016, date on which it was commissioned for service, committing a 79.35 MW, which represents 75.6%, of the turbine's power capacity. The remaining 24.4% capacity will continue to be compensated under SEE Resolution No. 19/2017.

CTLL estimates that the economic impact of the new remuneration will amount to $ 198 million for the previous period to the agreement's signing,which will be recognized in the Statement of Comprehensive Income under Revenues from sales as from this agreement's signing date.

2.1.4. SEE Resolution No. 287/17. Projects for Co-generation and Closing of Combined Cycles

Pursuant to SEE Resolution No. 420/2017, SEE Resolution No. 287/17 was published, which opened a call for bids to all parties interested in developing projects for co-generation and the closing of combined cycles over existing equipment, without limit to the power capacity to be installed. The projects should have low specific consumption (lower than 1,680 kcal/kWh with natural gas and 1,820 kcal/kWh with alternative liquid fuels).

It is a condition that the new capacity should not exceed the existing electric power transmission capacity; otherwise, the cost of the necessary extensions will be assumed by the Bidder.

2.2 Distribution

2.2.1.Tariff Structure Review

On January 31, 2017, the ENRE issued Resolution No. 63/17, pursuant to which it determined the definitive Electricity Rate Schedules, the review of costs, the required quality levels, and all the other rights and obligations that are to be applied and complied with by Edenor as from February 1, 2017. The above-mentioned regulation was adapted by the ENRE by means of the issuance of Resolutions Nos. 81/17, 82/17, and 92/17, and Note No. 124,898.

The aforementioned Resolution states that the ENRE, as instructed by the MEyM, shall limit the increase in the VAD resulting from the RTI process and applicable as from February 1, 2017, to a maximum of 42%, as compared to the VAD in effect at the date of issuance of the aforementioned resolution, with the remaining value of the new VAD being applied in two stages, the first of them in November 2017 and the last one in February 2018.

Additionally, the ENRE shall recognize and allow Edenor to bill the VAD difference arising as a consequence of the gradual application of the tariff increase recognized in the RTI in 48 installments as from February 1, 2018, which will be incorporated into the VAD’s value resulting as of that date. Furthermore, on July 27, 2017 the ENRE issued Resolution No. 329/17 establishes the procedure to aplly deferred revenue billing, bethose amounts will be adjusted as of February 2018 applying for such purpose the Methodology for the Redetermination of the Company’s Recognized Own Distribution Costs, set forth in caption c2) of Sub-Appendix II to ENRE Resolution No. 63/17.

As of June 30, 2017, the amount arising from the aforementioned limitation and not recognized by Edenor in these condensed interim financial statements amounts approximately to $ 2,315 million.

Despite the previously described progress achieved with regard to the completion of the RTI process, at the date of issuance of these condensed interim financial statements, the definitive treatment to be given, by the MEyM, to all the issues resulting from the non-compliance with the Adjustment Agreement, including the remaining balances and other effects caused by the partial measures adopted, has yet to be defined.

NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM

(in millions of Argentine Pesos (“$”) – unless otherwise stated)

NOTE 2:(Continuation)

These issues, among other, are the following:

i) the treatment to be given to the remaining balances of the amounts received for the fulfillment of the Investment Plan through the loans for consumption (mutuums) granted to cover the insufficiency of the funds deriving from the FOCEDE;

ii) the treatment to be given to the funds disbursed by Edenor for the fulfillment of the Investment Plan, not included in i) above;

iii) the conditions for the settlement of the balance outstanding with CAMMESA at the date of issuance of SE Resolution No. 32/15, for which purpose Edenor has submitted a payment plan;

iv) the treatment to be given to the Penalties and Discounts whose payment/crediting is pending.

Finally, on April 26, 2017 Edenor was notified that the MEyM had provided that, once the RTI process is completed, the SE -with the participation of the Under-Secretariat for Tariff Policy Coordination- and the ENRE, shall determine in a term of 120 days whether any pending obligations exist until the effective date of the electricity rate schedules resulting from the RTI, and in connection with the Adjustment Agreement entered into on February 13, 2006. In such a case, the treatment to be given to those obligations shall also be determined. Edenor has submitted the information requested by the MEyM in the framework of these issues and at the date of issuance of these condensed interim financial statements such situation is pending resolution.

2.2.2.Penalties

In addition to that which has been mentioned in note 2.3 to the financial statements as of December 31, 2016, in relation to the control procedures, the service quality assessment methodologies, and the penalty system applicable as from February 1, 2017 for the 2017 – 2021 period set out by ENRE Resolution No. 63/17, the Regulatory Entity, through Note No. 125,248 dated March 29, 2017, set new penalty determination and adjustment mechanisms, providing for the following:

i) Penalty values shall be determined on the basis of the kwh value, the average electricity rate, the cost of energy not supplied or other economic parameter at the value in effect at the first day of the control period or the value in effect at the date of the penalizable event for penalties arising from specific events.

ii) For all the events that occurred during the transition period (the period between the signing of the Adjustment Agreement and the effective date of the RTI) for which a penalty has not been imposed, penalties shall be adjusted by the consumer price index (IPC) used by the Argentine Central Bank (BCRA) to produce the multilateral real exchange rate index (ITCRM) for the month prior to the end of the control period or that for the month prior to the date of occurrence of the penalizable event for penalties arising from specific events, until the date on which the penalty is imposed. This mechanism is also applicable to the concepts penalized after April 15, 2016 (ENRE Note No. 120,151) and through the effective date of the RTI. This adjustment will be part of the penalty principal amount.

iii) Unpaid penalties will accrue interest at the BNA lending rate for thirty-day discount transactions from the date of the resolution to the date of actual payment, as interest on late payment. In the case of penalties related to Customer service, the calculated amount shall be increased by 50%.

iv) Penalties subsequent to February 1, 2017 will be valued at the Kwh value or the cost of energy not supplied of the first day of the control period or of the day of occurrence of the penalizable event for penalties arising from specific events. Those concepts will not be adjusted by the IPC, applying the interest on late payment established in iii) above. Moreover, an additional fine equivalent to twice the amount of the penalty will be determined if payment is not made in due time and manner.

The impact of these new penalty determination and adjustment mechanisms have been quantified by Edenor and recognized as of June 30, 2017.

In accordance with the provisions of Sub-Appendix XVI to ENRE Resolution No. 63/17, Edenor is required to submit in a term of 60 calendar days the calculation of global indicators, interruptions for which force majeure had been alleged, the calculation of individual indicators, and will determine the related discounts, crediting the amounts thereof within 10 business days. In turn, the ENRE will examine the information submitted by Edenor, and in the event that the crediting of such discounts were not verified will impose a fine, payable to the Treasury, equivalent to twice the value that should have been recorded. At the date of issuance of these condensed interim financial statements, Edenor is preparing the aforementioned information related to the six-month period ended July 31, 2017.

2.2.3.Framework agreement

On August 3, 2017, the approval of the extension until September 30, 2017 of the Framework Agreement was signed. The signing of the above mentioned agreement represents the recognition of revenue in favor of Edenor related to the distribution of electricity to low income neighborhoods and shantytowns for the January 1, 2015 - June 30, 2017 period for $ 203 million.

2.2.4Regulatory framework of Edenor – Law on electricity dependent patients

On May 17, 2017, Law No. 27,351 was passed, which guarantees the permanent and free of charge supply of electricity to those individuals who qualify as dependent on power for reasons of health and require medical equipment necessary to avoid risks in their lives or health. The law states that the account holder of the service or someone who lives with him/her (a cohabitant) that is registered as “Electricity dependent for reasons of health” will be exempt from the payment of any and all connection fees and will benefit from a special free of charge tariff treatment in the electric power supply service under national jurisdiction, which consists in the recognition of the entire amount of the power bill.

On July 26, 2017, the ENRE issued Resolution No. 292, stating that those discounts are to be made as from the effective date of the aforementioned law, and instructing CAMMESA to implement those discounts in its billing to distribution companies.The amounts paid by customers for the bills that fall within the scope of this Resolution will be made available in the stipulated time limits.

NOTE 4:(Continuation)

In Note 36 to the condensed interim financial statements the conditions of the compensation agreements, payment conditions and the main variables considered in the valuation model are detailed.

At the time of issuance of its next annual financial statements, the Company will apply the standards effective during fiscal year 2017 indicated in Note 4.2. to the Financial Statements as of December 31, 2016 (IAS 7: “Statement of Cash Flows” and IAS 12: “Income Taxes”). The Company estimates that these modifications will have no impact on the Company’s operating results or financial situation, but will only involve new disclosures.

As of June 30, 2016, the IASB has issued the following standards and interpretations:

IFRS 17 "Insurance contracts"

In May 2017, the IASB issued IFRS 17 that replaces IFRS 4, which was brought in as an interim standard in 2004 establishing the dispensation to carry on accounting for insurance contracts using national accounting standards, resulting in a multitude of different approaches. IFRS 17 establishes the principles for recognition, measurement, presentation and disclosure related to insurance contracts and shall by applied for annual reporting periods beginning on or after January1, 2021, permitting early application for entities that apply IFRS 9 and IFRS 15.

The Company is analyzing the impact of the application of IFRS 17, however, it estimates that the application of IFRS 17 will not have an impact on the results of operations or financial position of the Company.

IFRIC 23 "Uncertainty over Income Tax Treatments"

In June 2017, the IASB issued IFRIC 23 clarifying how to apply IAS 12 when there is uncertainty over income tax treatments to determine income tax. According to the interpretation, an entity shall reflect the effect of the uncertain tax treatment by using the method that better predicts the resolution of the uncertainty, either through the most likely amount method or the expected value method. Additionally, an entity shall assume that the taxation authority will examine the amounts and has full knowledge of all related information in assessing an uncertain tax treatment in the determination of income tax. The interpretation shall apply for annual reporting periods beginning on or after January 1, 2019, permitting early application.

The Company is analyzing the impact of the application of IFRIC 23, however, it estimates that the application of IFRIC 23 will not have material impact on the results of operations or the financial situation of the Company.

NOTE 7: INVESTMENTS IN SUBSIDIARIES

Merger of Subsidiaries

The following corporate reorganizations seek to derive important benefits for the Group, as they will allow for a higher operating efficiency, an optimized use of available resources, the leveraging of technical, administrative and financial structures, and the implementation of converging policies, strategies and goals. Furthermore, the high complementarity between the participating companies will be leveraged, thus reducing costs resulting from the duplication and overlapping of operating and administrative structures.

The merger's effective date was fixed on January 1, 2017, as from which date the transfer to the acquiring companies of the whole net worth of the acquired companies became effective, all the rights and obligations, assets and liabilities of the acquired companies thus being incorporated into the acquiring companies' net worth, all of which subject to the corresponding corporate approvals under the applicable law, the approval by the ENRE and the registration with the Public Registry of Commerce of the merger and the dissolution without liquidation of the acquired companies.

These reorganizations were implemented by means of a merger through absorption process, whereby the acquired companies will be dissolved without going into liquidation, subject to the provisions of the prior merger through absorption commitment, and sections 82 through 87 of theLey General de Sociedades No. 19,550 (Argentine Business Companies Law, or “BCL”) and its amending provisions, the CNV provisions, the BCBA Listing Rules and other provisions, the IGJ provisions and all other applicable legal and regulatory provisions in force.

Such values were calculated on the basis of the estimated market price of the Company’s corporate notes at the end of each period/year (Fair value category Level 1 and 2).

The book value of current borrowings approximates their fair value due to their short-term maturity.

Financial borrowings and CAMMESA financing approximate to their fair value as they are subject to a variable rate.

The other long-term borrowing were measured at amortized cost, which does not differ significantly from its fair value.

The main variations in the Group's financial structure during the six-month period ended June 30, 2017 and until the date of issuance of these unaudited condensed interim financial statements are described below.

As at the issuance of these condensed interim financial statements, the Company is in compliance with the covenants established in its indebtedness.

NOTE 28: EARNING (LOSS) PER SHARE

a) Basic

Basic earnings (loss) per share are calculated by dividing the result attributable to the Company’s equity interest holders by the weighted average of outstanding common shares during the period.

b) Diluted

Diluted earnings (loss) per share are calculated by adjusting the weighted average of outstanding common shares to reflect the conversion of all dilutive potential common shares.

Potential common shares will be deemed dilutive only when their conversion into common shares may reduce the earnings per share or increase losses per share of the continuing business. Potential common shares will be deemed anti-dilutive when their conversion into common shares may result in an increase in the earnings per share or a decrease in the losses per share of the continuing operations.

The calculation of diluted earnings (loss) per share does not entail a conversion, the exercise or another issuance of shares which may have an anti-dilutive effect on the losses per share, or where the option exercise price is higher than the average price of ordinary shares during the period, no dilutive effect is recorded, being the diluted earnings per share equal to the basic. As of June 30, 2016, the diluted earnings per share is equal to basic.

NOTE 33: ECONOMIC AND FINANCIAL SITUATION OF DISTRIBUTION SEGMENT

As a consequence of the delay in the compliance with certain obligations under the Adjustment Agreement, especially with regard to both the recognition of the semiannual rate adjustments resulting from the MMC, and the carrying out of the Tariff Structure Review (RTI), in addition to the constant increase in operating costs, in fiscal year 2016, Edenor recorded, as it did in fiscal years 2012 and 2014, negative operating and net results, deteriorating once again its economic and financial situation, which had temporarily improved in fiscal year 2015 as a consequence of the issuance by the SE of Resolution No. 32/15, which addressed the need for the adjustment of the distribution companies’ resources and considered that the adoption of urgent and interim measures was necessary in order to maintain the normal provision of the public service, object of the concession.

Despite the above-described situation, Edenor has absorbed the higher costs associated with the provision of the service and complied with the execution of the investment plan and the carrying out of the essential operation and maintenance works that are necessary to maintain the provision of the public service in a satisfactory manner in terms of quality and safety, which, in a context of constant increase in the demand for electricity, has deteriorated Edenor’s economic and financial equation over all these years.

Moreover, the measures adopted in 2016, aimed at resolving the electricity rate situation of the electric power sector, and the application of the RTI as from February 2017 will make it possible to gradually restore the economic and financial equation; thus, Edenor’s Board of Directors is optimistic that the new electricity rates will result in Edenor’s operating once again under a regulatory framework with clear and precise rules, which will make it possible not only to cover the operation costs, afford the investment plans and meet debt interest payments, but also to deal with the impact of the different variables that affect Edenor’s business.

As of June 30, 2017, the result of operations for the six-month period amounts to $ 369 million – profit-, whereas the working capital totals $ 3,824 million – deficit-, which includes the amount owed to CAMMESA for $ 4,182 million (principal plus interest accrued as of June 30, 2017). Edenor has submitted a payment plan proposal based on its available and projected cash flows, in respect of which no reply from CAMMESA has been received at the date of issuance of these condensed interim financial statements.

NOTE 34: DISCONTINUATION OF THE ARBITRATION PROCEEDING BEFORE THE ICSID

On March 28, 2017 the Secretariat of the World Bank’s International Centre for Settlement of Investment Disputes ("ICSID") took note of the discontinuance of the arbitration proceeding brought by EDF International and EASA in August 2003 regarding the breach of Edenor's concession agreement as a result of the passing of Public Emergency and Exchange Rate Regime Reform Act No. 25,561. The claimants' waiver was a condition of Edenor's Contract Renegotiation Memorandum of Understanding which had to be met after the issuance of the tariff scheme resulting from the Full Tariff Review, which was implemented through ENRE Resolution No. 63/2017 dated February 1, 2017 and is effective as from such date.

NOTE 35: REGULARIZATION REGIME (MORATORIUM)

Between the 29th and the 31st of March 2017, the Company adhered to the regularization regime (moratorium) provided for Law No. 27,260 in relation to certain tax claims and provisions. The Company related liabilities were mainly attributable to contingencies identified in Petrobras’s acquisition process including interpretation differences with the Argentine tax authority regarding i) the time of recording well abandonment expenses for income tax purposes, ii) the exemption from the Tax on Personal Assets as Substitute Taxpayer for the shareholder PPSL; iii) the Tariff heading used by the Company for certain exported products; and iv) inaccurate customs regarding the importation of a turbine supplied by Siemens Germany, including certain spare parts that had not been required nor declared by the Company. In relation to the last matter described before, the Company entered into an agreement with Siemens pursuant to which Pampa will receive the reimbursement of related incurred costs. As of December 31, 2016, the carrying amount of the matters that were included in the moratorium amounted to $ 1,332 million and $ 668 million disclosed as provisions and tax payables, respectively.

As the adhesion to the regularization regime provided for benefits of releasing tax fines and reducing compensatory interests, the Company has recorded on March 31, 2017 a net gain after income tax effects of $335 million, which in turn, generated the payment of approximately $171 million to Petrobras Brazil as contingent consideration payable in accordance to the share purchase agreement for the acquisition of Petrobras.On April 18, 2017, the Company paid this obligation.

Edenor´s Share-based Compensation Plan

In the last months of fiscal year 2016, Edenor’s Board of Directors proposed that the treasury shares be used for the implementation of a long-term incentive plan in favor of executive directors, managers or other personnel holding key executive positions in the Company in an employment relationship with the latter and those who in the future are invited to participate, under the terms of section 67 of Law No. 26,831 on Capital Markets. The plan was ratified and approved by the ordinary and extraordinary shareholders’ meeting held on April 18, 2017.

At the date of issuance of these condensed interim financial statements, Edenor awarded a total of 1,618,332 shares to executive directors and managers as additional remuneration for their performance in special processes developed during fiscal year 2016.

The fair value of the previously referred to shares at the award date, amounted to $ 42 million and has been recorded in the Salaries and social security taxes line item, with a contra account in Equity.

Pampa Energia

(i) Stock-based Compensation Plan - Specific Program for the 2017-2019 Period

On April 7, 2017, the Company's Shareholders’ Meeting ratified the approval of the Stock-based Compensation Plan by the Board of Directors on its February 8, 2017 meeting, as well as its terms and conditions; and approved the cancellation of the preferential offer to shareholders in respect to the disposition of such shares as authorized by Section 67 of Capital Markets' Act No. 26,831 for the purposes of implementing such Plan.

As of the issuance date of these Condensed Interim Financial Statements, the Company has determined that 383,198 treasury shares should be delivered to employees pursuant to the first Specific Program (2017-2019 period), with vests in March 2017, 2018 and 2019, of 33%, 33% and 34%, respectively.

As of the issuance date of these Condensed Interim Financial Statements, the Company has acquired 193,000 treasury shares and 92,280 treasury ADRs for an amount of $ 72 million, which will be destined to the implementation of the Company's Stock-based Compensation Plan.

(ii) Compensation agreements for the Company´s Senior Management

On June 2, 2017, the Board of Directors approved the execution and signing of compensation agreements with the Company’s main officers (the “Senior Management”), conditional upon their approval by the Annual Ordinary Meeting of Shareholders to be held each year. These agreements are effective as of January 1, 2017.

NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM

FINANCIAL STATEMENTS

(in millions of Argentine Pesos (“$”) – unless otherwise stated)

NOTE 36:(Continuation)

In accordance with international practices, the purpose of these agreements is to efficiently align the Senior Management’s interests with those of the Company and its shareholders, creating value for them only inasmuch as value is generated for shareholders, that is, if the Company’s market value increases.

Under these agreements, the Senior Management will be entitled to a fixed compensation and an annual, variable and contingent long-term compensation related to the Company’s annual market value appreciation, with a cap on the Company’s operating income

With the purpose of avoiding duplication, any analogous compensation that the Senior Management had received from any of the Company’s subsidiaries, will be deducted from the compensation amount in proportion to the Company’s interests in such subsidiaries.

As of June 30, 2017, the Company recognized in its income statement $ 78 million as the cost of such compensation indicated, offsetting entries $ 74 million in Other Payables and $ 4 millionin Equity

NOTE 37: CORPORATE REORGANIZATION

Following the acquisition of Petrobras Argentina, Pampa Energía started a corporate reorganization plan with the purpose of simplifying and maximizing the efficiency of the Company’s structure. The proposed reorganizations will allow the Company to derive significant operative and economic advantages, including, but not limited to, those associated with a higher operating efficiency; an optimized use of available resources, and the streamlining of technical, administrative and financial structures.

In this line, at the beginning of this year the merger of the Company, as absorbing company, with Petrobras Argentina S.A., Petrobras Energia Internacional S.A. and Albares Renovables Argentina S.A. was approved, which as at the date hereof is still pending registration with the Public Registry of Commerce, to which effect the Company is filing all applicable presentations with this body.

Furthermore, on June 26, 2017, Pampa Energía’s Board of Directors instructed the Company’s Management to start the proceedings to evaluate the potential benefits of a merger through absorption process between the Company, as absorbing company, and certain companies of the group, including: CTG, CTLL, CPB and EG3 Red, as absorbed companies.It is estimated that merger process would become effective reorganization date as from October 1, 2017.

NOTE 38: SUBSEQUENT EVENTS

Investment Agreement with YPF for the “Rincón del Mangrullo” Area

On August 1, 2017, YPF entered into an Agreement with the Province of Neuquén for the awarding of an unconventional exploitation concession in the Rincón del Mangrullo area, which will have to be approved by a provincial executive order.

The main commitments of the Agreement are as follows:

- A 35-year extension of the exploitation concession,

- A commitment to pay a Bond, a Corporate Social Responsibility Contribution and the stamp tax for a total amount of U$S 20 million, and

- An investment commitment of U$S 150 million aiming to further the development of the Mulichinco formation (tight gas) and to explore the potential of the Lajas and Vaca Muerta formations.

Although PEPASA will participate in this new unconventional concession in Rincón del Mangrullo jointly with YPF, its investment commitment will amount to 30% of the total amount agreed upon between YPF and the Province of Neuquén as PEPASA’s Agreement with YPF does not include the Vaca Muerta formation.

CTLL’s Loan

On July 28, 2017, CTLL executed a loan agreement for up to U$S 55 million with Finnish Export Credit Limited; this credit facility was structured by Crédit Agricole Corporate and Investment Bank (“CACIB”) with the purpose of partially financing the installation of a new Wärtsilä engine generator power plant with a 100 MW capacity in Ingeniero White.

The loan’s disbursement is conditional upon the satisfaction of the conditions precedent stipulated in different parts of the agreement, which have not been wholly fulfilled yet.

The loan will be secured by a credit guarantee, 95% of which will be granted by Finnvera Plc. (the Export Credit Agency of the Republic of Finland), and the remaining 5% of which will be granted by CACIB; as well as a guarantee to be granted by the Company.

The loan will accrue interest at a variable rate consisting of the six-month LIBO rate plus and a guarantee premium on the principal in consideration of the credit guarantee to be granted by Finnvera Plc and CACIB.

Principal will be repaid in 14 semiannual, equal and consecutive installments, the first one maturing six months as from: (i) the commercial commissioning of the plant, or (ii) November 25, 2017, whichever occurs earlier.

Thermal Generation Projects (SEE Resolution No. 21/16)

Under the Wholesale Demand Agreement executed between CAMMESA and CTLL as awardee under the Call to Companies interested in Offering New Generation Capacity pursuant to SEE Resolution No. 21/16, on August 5, 2017, CAMMESA declared the commercial commissioning of the new 105 MW high-efficiency gas turbine.

It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any materialmodifications that should be made to the accompanying unaudited consolidated condensed interim financial statements for them to be in conformity with International Accounting Standard 34 “Interim Financial Reporting”, as issued by the International Accounting Standard Board.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidatedstatement of financial position as of December 31, 2016, and the related consolidated statements of comprehensive income (loss), changes in equity and of cash flows for the year then ended (not presented herein), and in our report dated April 26, 2017, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidatedstatement of financial position as of December 31, 2016, is fairly stated, in all material respects, in relation to the consolidatedstatement of financial position from which it has been derived.
