Ref. Transportadora de Gas del Sur S.A. (“TGS”)

Dear Sirs,

Please be informed that on November 7, 2008, after closing time, TGS’ Technical Operator –Petrobras Energía S.A- notified its approval to the renewal of the Technical Assistance Agreement (TAA)- which would have expired on 12/28/08- for a three-year term, wihout an automatic renewal provision.

In compliance with section 73¹ of Law 17,811 of the Argentine Securities and Exchange Commission, on October 31, TGS’ Board of Directors requested the Audit Committee to evaluate said transaction. The Audit Committee members issued a report concluding that the transaction can be reasonably considered in arm’s length terms and under ordinary and regular market conditions. In order to draw up said report, the Audit Committee requested the opinion of two (2) external specialists.

Therefore, the Board of Directors -on its meeting held on November 5, 2008- approved to continue with the technical assistance under the terms of the TAA, subject to approval by the Technical Operator of the amendments proposed by TGS, which were later approved, as mentioned in the first paragraph of this letter.

Finally, it should be pointed out that the Audit Committee’s opinion, as well as the reports issued by the external specialists on which said opinion was based, are available for consultation by accredited shareholders if so desired, at TGS’ principal office, located at Don Bosco 3672 of the Autonomous City of Buenos Aires (Ms. Valeria Kappel, extension #1211).

Sincerely,
