HIGHLIGHTS

Resolution No. 32/15 of the Secretariat of Energy (SE)

In March 2015, the SE issued Resolution N° 32/15 granting us a temporary increase in income through funds provided by CAMMESA, applicable retroactively as from February 1, 2015, to pay for costs and investments associated with the regular provision of the public service of distribution of energy on account of the future Integral Tariff Revision (RTI). The Additional Income results from the difference between the "theoretical" tariff schedules set forth in such resolution and the current tariff schedule in force for each category of users, according to calculations made by the ENRE, which must be reported monthly to the SE and CAMMESA. In this respect, CAMMESA transfers the funds contributed by the Argentine government, in accordance with the values reported by the ENRE.
As from February 1, 2015, the PUREE funds will be considered as part of Edenor's income on account of the future RTI. At the same time, we are entitled to offset the debts for PUREE with claims arising from the calculation of CMM until that date, including the application of set interests. In addition, CAMMESA was instructed to issue LVFVD (Sale Settlements with Maturity Dates to be Determined) for the surplus amounts in favor of the Company, resulting from the offsetting process indicated in the preceding paragraph, and for the amounts owed by the Company under the Loans for consumption granted for higher salary costs.
We shall agree with CAMMESA a payments plan to cancel the obligations owed to it for the provision of electricity. Additionally, under this Resolution, certain restrictions are applied. We may not use the income arising from Resolution No. 32/15 to cancel credit from financial institutions, financial debt restructuring, acquire other companies, extend credit, or perform other operations that are not strictly related to the cancellation of obligations with CAMMESA, payment of salaries, and payments to suppliers for goods and or related to the provision of public electricity distribution services.
Resolution established that we shall comply with Clause 22.1 of the Adjustment Agreement and suspend any administrative or judicial claims that may have been initiated against the Argentine government in relation to compliance with clause 4.2 of the Adjustment Agreement. As of the date of this annual report, our board of directors was analyzing the scope of this provision and evaluating its impact on us.

Loans agreements with CAMMESA for Extraordinary Investment Plan - Temporary insufficiency of the income deriving from the FOCEDE

In September 2014, the Energy Secretariat instructed CAMMESA to enter into a Mutuum and Guarantee Assignment Agreement with the Company for an initial amount of AR$ 500 million in order to provide the necessary financing to cover the Extraordinary Investment Plan as a consequence of the temporary insufficiency of the revenue deriving from Resolution 347/12. On December 2014, this agreement was extended, for an additional amount of AR$
159.4 million and subsequent to year-end, on January 2015 and March 2015, new extensions were filed, they totalized an available amount of AR$ 2,006.2 million.
As of March 31, 2015, these debt amounts to AR$ 714.5 million, comprised of AR$ 677.8 million principal and
AR$ 36.7 million in accrued interest.

First Quarter 2015 Operating Figures

In millon of Pesos 1° Q 2015 1° Q 2014 % Variation

Revenue from sales 968.6 900.6 7.6%

Electricity power puchase (523.0) (439.7) 18.9%

Net operating income (loss) 916.0 (377.8) n/a

Net income (loss) 469.9 (738.6) n/a

Revenue from sales increased 7.6% to AR$ 968.6 million in the first quarter of 2015 compared to AR$ 900.6 million in the first quarter of 2014, mainly due to an increase in volume of energy sold. Volume of energy sold increased 6.9% to 5,562 GWh in the first quarter of 2015 from 5,204 GWh in the first quarter of

2014, mainly due to an increase of 19.1% in small commercial customers, a 7.7% in the sales to residential customers and a 3.9% increase in industrial and wheeling system demand.

Electricity power purchases increased 18.9% to AR$ 523.0 million in the first quarter of 2015 compared to AR$ 439.7 million in the first quarter of 2014, mainly due the increase in energy sales described above, to an increase in energy losses and lesser extent to an increase in mobile generation. Net operating income increased AR$ 1,293.8 million amounting a gain of AR$ 916 million in the first quarter of 2015 compared to a loss of AR$ 377.8 million in the same period of 2014. This positive result was due to the income increase obtained through Resolution 32/15 of AR$ 1,333.9 million (this increase is composed by AR$ 708.2 million additional income obtained from the difference between the "theoretical" tariff schedule and the current tariff schedule, AR$ 464.8 million corresponded to the offset of the debt arising from loans granted by CAMMESA in connection with the mandatory salary increases and AR$160.8 million from the PUREE funds that will be considered as part of Edenor's income).

These increases were partially offset by higher transmission and distribution expenses of AR$ 114.8 million, by administrative expenses of AR$ 48.8 million and selling expenses of AR$ 38.3 million. The main expenses increased due
to a raise in salaries of AR$ 176.6 million and a growth in consumptions of materials of AR$ 18.8 million.

Net income shows an increase of AR$ 1,208.5 million, amounting a gain of AR$ 469.9 million in the first quarter of 2015, compared to a loss of AR$ 738.6 million in the same period of 2014, mainly due to the income recognition of Resolution

32/15 described above, to the recognition of higher costs through the application of the Resolution 250/13 and subsequent Notes for a total amount of AR$ 186.6 million and to a decrease of AR$ 181.1 million in financial results due to a lesser devaluation registered in 2015, partially offset by the cost increases described before.
