TRANSLATION

Autonomous City of Buenos Aires, January 9, 2017

To the

Bolsa de Comercio de Buenos Aires

(Buenos Aires Stock Exchange)

Re: Agreement among YPF S.A. ("YPF" or the "Company"), AES Uruguaiana Empreendimentos S.A. and Companhia de Gás do Estado do Rio Grande do Sul.

Dear Sirs:

The purpose of this letter is to comply with the requirements of Article 23 of Chapter VII of the Buenos Aires Stock Exchange Regulations.

In that connection, and pursuant to our previous communications dated May 24, 2013, December 23, 2015 and April 27, 2016, as well as the disclosures in the Company's Financial Statements, we report that, as a result of the legal and commercial complexities of the dispute between YPF S.A., AES Uruguaiana Empreendimentos S.A. and Companhia de Gás do Estado do Rio Grande do Sul, as well as the existence of litigation rights in different jurisdictions around the world (including the Republic of Argentina, the Eastern Republic of Uruguay and the United States of America), these companies entered into an agreement for the sole and total sum of US$60,000,000 through which, without recognizing facts or rights, AES Uruguaiana Empreendimentos S.A., Companhia de Gás do Estado do Rio Grande do Sul and YPF S.A. withdrew all claims that they had or could have had until this date, with the exception, in the case of YPF, of the appeals for annulment filed against the arbitral awards, which remain in full force and effect.

Yours faithfully,

Diego Celáa

Market Relations Officer

YPF S.A.
