Ref: Material Fact

Dear Sirs,

I hereby address you on behalf of Empresa Distribuidora y Comercializadora Norte S.A. (EDENOR) (the “Company”) in accordance with the regulations in force in order to notify that this Distributor has been informed that the Board of Directors of Electricidad Argentina S.A. (“ EASA ”), EDENOR’s parent company, in the meeting held on March 29th approved, ad referendum of the corresponding assembly resolutions and the corresponding approvals of the controlling entities, the merger by absorption between Central Térmica Loma de la Lata S.A. (“CTLL”), as merging and continuing company, and EASA e IEASA S.A. (“IEASA”) - the latter the last EASA’s majority shareholder – as the merged/absorbed company, which will be dissolved without liquidation. Likewise, the Merger Plan was approved as well as the Merger Consolidated Income Statement. It is important to point out that both CTLL, the merging and continuing company, and EASA e IEASA, the merged/absorbed company, belong to the same controlling group, since Pampa Energía S.A. is the direct and/or indirect controlling shareholder of all of them.

In accordance with the applicable regulations, today, EDENOR and EASA have also informed and requested the corresponding authorization to the National Regulatory Entity for Electricity ("ENRE").

Yours faithfully,

Carlos D. Ariosa

EDENOR S.A.
