One) In Respect of the Companies. The Companies are legal mining companies subject to articles one hundred and seventy-three et seq. of the Mining Code. They were established by the so-called “Proyecto de Maricunga” project, located in the north-eastern section of the Maricunga Salt Flats in the Region of Atacama. The properties extend in the aggregate over a surface area of approximately 1,438 hectares. Each of the Companies has the following shareholders, each holding the following number of shares: (i) Minera Li Energy S.p.A., sixty shares (60); (ii) María Ana Parot Donoso, fourteen shares (14); (iii) Tomás Eduardo Serrano Parot, ten shares (10); (iv) Rosario Serrano Parot, four shares (4); (v) Valeria Serrano Parot, four shares (4); (vi) Ernesto De Val Gutiérrez, four shares (4); and, (vii) Jorge Osvaldo Fuenzalida Barraza, four shares (4). Two) Non-fulfillment by the Minority Shareholders. On October 6, 2011, the absolute majority of the shares present at the shareholders’ meeting agreed unanimously, inter alia, to establish a quota to cover the conservation and exploration costs of the mining concession of each of the Companies. Each of the agreements reached at the meeting were formalized in a public instrument. To date none of the Minority Shareholders have paid their quota to cover the conservation and exploration costs of the properties. Consequently, the Minority Shareholders are non-fulfilling partners in respect of the Companies. Three) Non-fulfillment Lawsuits. In accordance with articles one hundred and ninety-six et seq. of the Mining Code, Minera Li Energy S.p.A., in its capacity as managing partner of each of the Companies, filed thirty-six (36) executive complaints in mining non-fulfillment lawsuits against each and every one of the Minority Shareholders in order to obtain full payment of their respective quotas to cover the corporate expenses. In total, these are 36 non-fulfillment lawsuits that in the aggregate seek to obtain payment of a debt equivalent to two million three hundred and five thousand five hundred and fifty-eight dollars ($2,305,558) of the United States of America (hereinafter, jointly and indistinctly, the “Non-fulfillment Lawsuits”) and that are specifically directed against minority partner Mr. Ernesto De Val Gutiérrez in the sum of two hundred and thirty thousand five hundred and fifty-five dollars of the United States of America ($230,555), as follows:
