Dear Sirs,

I am writing to you, in my capacity as Head of Market Relations of Transportadora de Gas del Sur S.A. ("TGS"), in order to report that today TGS was served notice of the judgement rendered by Panel I of the Federal Administrative Court in the proceedings entitled “Transportadora de Gas del Sur S.A. c/ Resolución N° I-1.991/11 y N° I-1.982/11 ENARGAS (Expte. 14.215/08) s/ Proceso de conocimiento”, File N° 11.869/2012 (the “Judgement”).

As timely reported on March 27, 2019, in 2012 TGS requested the declaration of unconstitutionality of Executive Decree no. 2067/08, of Resolution no. 1451/08 issued by the Ministry of Federal Planning and Public Investment (“MPFIP”) and Resolutions no. 1982/11 and 1991/11 issued by the National Gas Regulatory Body (ENARGAS) (the “Resolutions”), as well as of any other regulation or act issued or to be issued in connection with these resolutions (the “Resolutions contested”), whereby  a charge had been created with the aim of financing natural gas imports carried out by the Argentine Government.

It is worth mentioning that the First Instance judgement rendered in the proceedings upheld the legal action filed by TGS, while the current Judgement –which is not final yet- (i) has reversed the previous judgement and (ii) has awarded costs at both instances to be borne equally by the parties.

TGS believes that it has solid arguments to defend its position in the background issue posed, and therefore it will challenge the Court Judgement.

Yours sincerely,



Hernán Diego Flores Gómez

Head of Market Relations
