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

Dear Sirs,

The purpose hereof is to inform -pursuant to the requirements of the regulations under the United States Securities and Exchange Act- that in line with Section 2 of Resolution no. 31/2016 issued by the Ministry of Energy and Mining, which was published in the official gazette on April 1, 2016 (“Resolution 31”), the Gas Regulatory Body (“ENARGAS”) issued Resolution no. I/3724/2016, published today in the official gazette, whereby the ENARGAS approves, starting April 1, 2016, the tariff charts for natural gas transportation public utilities carried out by TGS, which implies a 200.1% increase, representing a 5% increase for end users (the “Increase”).

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 “ITR Process”), and subject to compliance with the Mandatory Investment Plan undertaken for the next 12 months and to be overseen by the ENARGAS (the “Investment Plan”).

Lastly, and following Section 7 of Resolution 31, 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,

Nicolás M. Mordeglia

Attorney in Fact
