Dear Ladies and Gentlemen:

In my capacity as the Chairman of the Corporate Practices Committee (the “Committee”) of Vista Oil & Gas, S.A.B. de C.V.

In consideration of the provisions contained in the SMA, during the relevant fiscal year, the Committee generally focused on carrying out the corporate practices activities that the applicable law and the by-laws of the Company confers on the Committee, in order to assist the Board of Directors in the management of the Company, and holding periodic and regular meetings with different relevant officers of the Company, and consequently to ensure the prudent management of the Company and its various projects.

With regard to specific concepts corresponding to the functions approved for this Committee, we present the following results:
