Subsequently, by Decree No. 772/15 dated April 24, 2015, the Province of Neuquén authorized YPF, as holder of the LACh concession, to assign 50% of the total rights, titles and obligations to PEPASA. In turn, Decree No. 772/15 authorized PEPASA to assign 100% of its stake (equivalent to 50% of LACh) as collateral to YPF, under the terms of Article 73 of the Argentine Hydrocarbons Law. For this purpose, TMF Trust Company (Argentina) SA was appointed as the Local Security Agent and TMF Canada Management Inc. as the Security Agent. This guarantee is no longer in effect as of the date of this disclosure document. On December 10, 2014, YPF and PEPASA entered into a joint venture agreement (the “ JV Agreement” and the “ JV”) which is duly registered with the Argentine commercial registry. The main purpose of the JV Agreement is the exploration, evaluation, development and exploitation of hydrocarbons in the LACh unconventional exploitation concession. The JV Agreement includes references to the distribution of profits and losses in proportion to the parties’ percentages of working interest in the Concession; the designation of YPF as operator and representative of the JV; provisions for dispute resolution (negotiation, mediation, arbitration), among other issues. The JV Agreement will be in force for a period equal to that of the LACh concession and includes provisions for asset reversal and liquidation. From the Completion Date, Vista will take over PEPASA’s contractual position in the JV Agreement. 16

Additionally, on September 24, 2019, YPF and PEPASA entered into a joint operating agreement (the “ JOA”) aimed at establishing certain terms and conditions regarding the operation of the LACh area. The key aspects of the JOA include detailed provisions on work programs, budgets, and expenditure authorizations; the allocation of costs and revenues; stipulations for sole risk operations; and clear guidelines for termination and assignment of working interest. The JOA also incorporates several annexes detailing technical and operational aspects. From the Completion Date, Vista will assume PEPASA’s contractual position in the JOA. As a result of the corporate restructuring, Vista, through PEPASA, will become the owner of the 50% non-operatedworking interest in the LACh concession, located in Vaca Muerta, Neuqu
