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

Dear Sirs,

In accordance with the requirements set forth in the regulations under the United States Securities and Exchange Act, we hereby report that, in line with the provisions of Section 7 of Resolution no. 212/2016 (“Resolution 212”) issued by the Ministry of Energy and Mining (“MINEM”) - published in the Official Gazette on October 7, 2016-, the Regulatory Gas Body (“ENARGAS”) issued Resolution no. I/4054/2016 (“Resolution 4054”) –also published on October 7, 2016-. The later approves, starting October 7, 2016, the tariff charts for natural gas transportation public utilities carried out by TGS (the “Increase”).

Thus, the tariff adjustment is implemented, following (i) the provisions of the Transitory Agreement entered into on February 24, 2016 by and among MINEM, the Ministry of Public Finance and TGS (the “Transitory Agreement”), and (ii) ENARGAS’ approval through Resolution no. I/3724/16, issued in line with Section 2 of MINEM Resolution 31/2016 (both Resolutions were annulled by the Supreme Court of Justice through judgment rendered on August 18, 2016 in case “Centro de Estudios para la Promoción de la Igualdad y Solidaridad y otros c/ Ministerio de Energía y Minería s/Amparo Colectivo”, with respect to residential users).

The Increase was granted on the grounds of TGS’ economic and financial situation and must be regarded on account of the Integral Tariff Review.

The Increase is subject to compliance with a Mandatory Investment Plan pursuant to Resolution 4054 (the “Investment Plan”).

In accordance with the provisions of Section 7 of Resolution 212 and the Transitory Agreement, TGS shall not be allowed to pay dividends without the ENARGAS’ prior authorization, to which end evidence of compliance with the Investment Plan shall be submitted.

Sincerely,

Silvia Migone Díaz

Attorney in Fact
