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 on November 8, 2010, TGS’ CEO informed of the resignation of Mr. Jorge Bonetto, TGS’ Operations Manager, effective November 30, 2010, and the subsequent appointment of Mr. Benjamín Guzmán in replacement.

Furthermore, we hereby inform you that on November 8, 2010 the Company was served notice of the judgment that upheld the injunction filed by TGS – notified by letter to the SEC on October 1, 2010. Said judgment orders the Coordination and Management Control Undersecretariat -under the scope of the Ministry of Federal Planning, Public Investment and Services- to return to Enargas (Gas Regulatory Body) –within a 2-day period- the documents remitted by said Body in connection with the Tariff Chart applicable to TGS under Decree no. 1918/09; and orders the Enargas –within 2 days following reception of said documents- to set the Tariff Chart and the retroactive collection methodology. The judgment is not final yet.

Sincerely,

Adrián Hubert

Attorney in Fact
