Ref.: Relevant Information (Art. 23)

Dear Sirs:

Through Resolution ENRG No. I-1260 dated June 17, 2010 (the "Resolution"), the ENARGAS (National Gas Regulator Entity) ordered that for the next 120 days MetroGAS will continue to manage its business under the supervision of an ENARGAS-appointed supervisor (the "Interventor") and, consequently, appointed Antonio Gómez (LE No. 5.071.379) as MetroGAS's Interventor.

As per the Resolution, such decision follows the announcement made by the Company on June 17, which was filed with the National Securities Commission and the Argentine Stock Exchange, Bolsa de Comercio, as a result of the MetroGAS Board of Directors decision to file for reorganization proceedings under Argentine Law (similar to US Chapter 11).

The Resolution states that the Interventor will (a) supervise and control all MetroGAS's activities that could have an impact in the public service gas supply rendered by Metrogas, which is the core of the license agreement; (b) initiate a corporate audit of MetroGAS; and (c) individualize and valuate all MetroGAS' assets.

The Company is currently analyzing the actions it will implement.

Without any further comments,
