In accordance to what is established by the Regulation for Relevant Information Communications and Reserved Information, we hereby inform you that the Company has analyzed the Urgency Decree (Decreto de Urgencia) N° 003-2017 (hereinafter “the Decree”), which aims to approve the measures that prevent the stoppage of the public works or partnerships between private and public entities and any contingency in the payment processes that put in risk the economic performance of the country, as a consequence of corruption acts, establishing in its article 2 the entities to which the dispositions of the Decree apply.

Regarding the above, we will explain the reasons why our company is not subject to the Decree and its guidelines, either directly or as “related” (vinculada) in accordance with the following:

Article 2.1 of the Decree establishes which legal entities are subject to the restrictions provided therein; namely: (i) those companies condemned or whose officers or representatives have been condemned in the country or abroad by final resolution (unappealable) or enforced sentence for crimes against public administration or money laundering, or equivalent crimes in case they were committed abroad to the detriment of the government; (ii) that, directly or through its representatives, they would have admitted and / or recognized committing any of the crimes before-mentioned to any competent national or foreign authority; and (iii) to those entities related to those referred to in paragraphs (i) and (ii) above.

In this sense, our company, its officials or representatives, have not been condemned, nor have they admitted committing the crimes mentioned by the Decree and therefore it is not directly subject to it.

On the other hand, the Company is not configured as related to any company that is subject to paragraphs (i) and (ii) above, as said word has been defined in article 2.2. of the Decree.

Based on the above, we can conclude that, based on the analysis carried out by the Company, we are not subject to the Decree or its ancillary dispositions.

Sincerely,
