Re.: Transportadora de Gas del Sur (“TGS”)

Dear Sirs,

The purpose hereof is to inform you -in accordance with the requirements of the regulations under the United States Securities and Exchange Act- that today Compañía de Inversiones de Energía S.A. (CIESA) – TGS’ parent company- notified us that Miss Kitty LLC and Sundance Spain Holdings SL, shareholders of Enron Pipeline Company Argentina S.A. (EPCA) –shareholder of 63,881,870 class B3 shares, which represent 10% of CIESA’s capital stock (638,818,696 shares with voting right)- transferred all their equity interest in EPCA to Pampa Energía S.A. and Pampa Participaciones S.A. (a subsidiary corporation of Pampa Energía S.A.).

As a result of EPCA’s takeover, today Mr. Mariano Pablo Gonzalez and Pablo Alejandro Melhem Marcote, TGS’ Director and Alternate Director respectively (appointed by the shareholders’ meeting held on April 16, 2010) submitted their resignation effective April 8, 2011.

The Board immediately accepted their resignation, subject to approval by the next shareholders’ meeting, which will be held on April 29, 2011.

The Board also requested the Statutory Audit Committee to appoint two Directors to fill the vacancies. The Statutory Audit Committee appointed Mr. Gustavo Mariani as Director and Mr. Marcos Marcelo Mindlin as Alternat Director, both in their capacity of non-independent Directors, and afterwards appointed Mr. Mariani as Board Vice Chairman.

Sincerely,
