Re: EDENOR S.A. – Material fact -

Dear Sirs:

I hereby address you on behalf of Empresa Distribuidora y Comercializadora Norte S.A. (EDENOR) (the “Company”) in compliance with applicable laws and regulations, in order to inform that the Company has received from the Wholesale Electric Market Management Company (“CAMMESA”) and following instructions from the Department of Energy, acting within the frame of Resolution SE 32/2015, a wire transfer for the amount of $ 282.964.521 corresponding to the retro-time adjustment of income generated by said resolution for the period May-October of this year, resulting from the partial application of the adjustments of the Cost Monitoring Mechanism (CMM) whose index, for the first semester, has been established in 7,2% by the ENRE (National Regulatory Entity for Electricity).

Although the Company is analyzing the scope of the decision, the above mentioned does not imply a tariff increase to the users of the service.

Best regards,

Carlos Ariosa

Attorney-in-fact
