(1) By Bienville Argentina Opportunities Master Fund, LP ("Argentina Fund"). The Reporting Person serves as the portfolio manager of the registered investment adviser to Argentina Fund, and as such he could be deemed to indirectly beneficially own the shares held by Argentina Fund. The Reporting Person disclaims beneficial ownership of the shares, except to the extent of his pecuniary interest therein, and this report shall not be deemed an admission of beneficial ownership of these securities for Section 16 or any other purposes.
(2) By Bienville Argentina Opportunities Fund 2.0, LP ("Argentina Fund 2"). The Reporting Person serves as the portfolio manager of the registered investment adviser to Argentina Fund 2, and as such he could be deemed to indirectly beneficially own the shares held by Argentina Fund 2. The Reporting Person disclaims beneficial ownership of the shares, except to the extent of his pecuniary interest therein, and this report shall not be deemed an admission of beneficial ownership of these securities for Section 16 or any other purposes.
(3) On April 3, 2017, 1,507,696 shares of the Issuer were transferred by Argentina Fund to Argentina Fund 2 as part of an in-kind distribution of assets by Argentina Fund to certain of its investors who have elected to rollover all or a portion of their investment in Argentina Fund to Argentina Fund 2 via an in-kind contribution of securities to Argentina Fund 2. Accordingly, there was no change in beneficial ownership of any investors in either Fund with respect to the shares of the Issuer as a result of the transaction. With respect to the Reporting Person, the transaction only effected a change in the form of beneficial ownership without changing the Reporting Person's pecuniary interest in the shares and was exempt from Section 16 of the Securities Exchange Act of 1934 pursuant to Rule 16a-13.
