15.1	Lacus shall have the obligation to keep the Properties in good standing according to Applicable Laws. In this sense, the Mining Fee and the investments plan obligations are to be complied with for the Properties in due time.

In this regard, it is expressly agreed that:

(a)

evidence of the Mining Fee payments will be provided to LI3 on each opportunity of payment. LI3 shall be responsible for the costs involved to keep the Properties in good standing as of the Closing Date and Lacus shall inform LI3 regarding any payments due with an anticipation of one month in order to have enough time to anticipate the funds in due time. After payment by Lacus, Lacus shall furnish LI3, within 5 calendar days from the applicable payment, with copy of the relevant receipt evidencing payment thereof.

(b)

in connection with the investment plan, if the obligation to file such plan in connection with the Properties or some of the Properties is due prior to exercise of the First Option, then the Executive Committee will agree and decide on the content and scope of such investment plan or plans as required by Applicable Laws.

(c)

the strategy to manage the Properties and therefore any mandatory or non mandatory filings or presentations to be made in the files will be expressly agreed and discussed within the Executive Committee.

15.2

The Executive Committee will have the right at any time during the First Exploration Phase to decide whether any Properties are to be excluded or extended or in other way decide regarding the strategy to manage and handle the Properties, eg. formation of a mining group, application of easements to develop mining infrastructure, etc.

15.3

In connection with the maintenance of the Properties in good standing and for all legal purposes, Lacus grants an Irrevocable Power of Attorney to LI3 in order to directly exercise any actions that may be required to keep the Properties in good standing and/or to cure any omission incurred by Lacus in connection with such actions.

SECTION 16 – AREA OF MUTUAL INTEREST

The Parties agree that any acreage outside the Properties within the three Salars, identified as Centenario, Pocitos and Xxxxxx Salars and as described in Schedule “II” constitutes an area of mutual interest where acquisitions or disposition of AMI Properties will be coordinated and agreed by the Executive Committee

It is further agreed that such area of mutual interest (“AMI”) will only include lithium and potash mining properties which are in an early stage of exploration and therefore the Parties will not be prevented from entering into agreements with other third parties regarding projects which are excluded from the AMI and/or projects that are not in an early stage of exploration and/or which do not relate to lithium or potash, except for any properties related to the Third Parties Option Agreements while in force.

In the case LI3 decides to develop any other project in the vicinity of the AMI, LI3 shall always make the best efforts to allow the different projects to reach Commercial Production and mutually benefit from infrastructure, water, etc.

SECTION 17 – RELATIONSHIP BETWEEN THE PARTIES AS FROM EXPIRATION OF SECOND EXPLORATION PHASE

17.1	Governing Body. The Mining Operations in the Properties will be conducted by the Newco, in accordance with the Shareholders´ Agreement and the decisions adopted by the Management Committee.

17.2	Expenditures. Each Party will thereafter be responsible for its pro rata share of Expenditures, as stated in Section 11.3 hereof.

17.3

Funding of Newco. Funds required by Newco for its operations and for payment of expenditures and any other expenses in connection with the Properties and operations thereon will be advanced to Newco by the Parties in such manner (i.e. by way of shareholder loans, subscriptions for additional shares of Newco or other procedure) as determined by the Management Committee, which will determine the most tax-efficient method for the making of such advances, taking into account the potential repayment thereof.

17.4

Failure in Funding the Newco. Failure by a Party to provide its share of a cash call funds within the term indicated by the Shareholders´ Agreement and the Management Committee will be deemed to be an election by such Party that it is not participating in such cash call and the Management Committee will be entitled to invite the other Party to contribute such shortfall, provided that such action would result in a dilution of the interest of the relevant Party in the Newco.

17.5	Dilution to Net Profits Interest

(a)

Upon the dilution of the shareholding participation of a Party to less than ten (10%) percent, such Party will have to transfer all of its Newco’s shares to the other Party, in consideration of a right to receive payments from Newco equal to a percentage of the net profits from the operation exclusively of the Properties (such term and percentage to be defined by the Parties as of the Closing) - and without taking into account any profits derived from operations being conducted in combination with other mining properties.

(b)

Upon the dilution of the shareholding participation of a Party to less than fifteen (15%) percent and provided that Section 17.5(a) does not apply, such Party will have the option –at its sole discretion- to transfer all of its Newco’s shares to the other Party, which consideration or parameters for such shall be defined by the Parties as of the Closing..

(c)

Following a transfer pursuant to Section 17.5(a) or 17.5(b) above, the Party holding the net profits interest pursuant to Section 17.5(a) or beneficiary of the benefit or consideration pursuant to Section 17.5(b) will no longer be a Party neither a shareholder of the Newco, provided that the foregoing will not relieve such Party of its share of any liability, whether it accrued before or after reduction or conversion, arising out of operations conducted prior to such reduction or conversion. A former Party’s share of such liability will be equal to its pro rata share interest at the time that such liability was incurred.

Lacus is acquiring the LI3 Shares for investment for its own account and not with the view to, or for resale in connection with, any distribution thereof. Lacus understands and acknowledges that the LI3 Shares have not been registered under the Securities Act or any state or foreign securities laws, by reason of a specific exemption from the registration provisions of the Securities Act and applicable state and foreign securities laws, which depends upon, among other things, the bona fide nature of the investment intent as expressed herein. Lacus further represents that it does not have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participation to any third person with respect to any of the LI3 Shares.

(ii)

Lacus understands that an active public market for LI3 Common Stock may not now exist and that there may never be an active public market for the LI3 Shares acquired under this Agreement.

(iii)

Lacus either (i) is an “accredited investor” as defined in Rule 501 of Regulation D as promulgated by the Securities and Exchange Commission under the Securities Act or (ii) is not a “U.S. Person” as defined in Regulation S as promulgated by the Securities and Exchange Commission under the Securities Act, and, in each case, shall submit to LI3 such further assurances of such status as may be reasonably requested by LI3.

(iv)

Lacus, if a non-U.S. Person, agrees that it is acquiring the LI3 Shares in an offshore transaction pursuant to Regulation S and hereby represents to LI3 as follows:

Lacus is outside the United States when receiving and executing this Agreement;

Lacus has not acquired the LI3 Shares as a result of, and will not itself engage in, any “directed selling efforts” (as defined in Regulation S) in the United States in respect of the LI3 Shares which would include any activities undertaken for the purpose of, or that could reasonably be expected to have the effect of, conditioning the market in the United States for the resale of the LI3 Shares; provided, however, that Lacus may sell or otherwise dispose of the LI3 Shares pursuant to registration of the LI3 Shares under the Securities Act and any applicable state and provincial securities laws or under an exemption from such registration requirements and as otherwise provided herein;

Lacus understands and agrees that offers and sales of any of the LI3 Shares prior to the expiration of a period of one year after the Closing Date (the “Distribution Compliance Period”), shall only be made in compliance with the safe harbor provisions set forth in Regulation S, pursuant to the registration provisions of the Securities Act or an exemption therefrom, and that all offers and sales after the Distribution Compliance Period shall be made only in compliance with the registration provisions of the Securities Act or an exemption therefrom, and in each case only in accordance with all applicable securities laws;

Lacus understands and agrees not to engage in any hedging transactions involving the LI3 Shares prior to the end of the Distribution Compliance Period unless such transactions are in compliance with the Securities Act; and

Lacus hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the LI3 Shares or any use of this Agreement, including: (a) any applicable legal requirements incumbent upon Lacus within its jurisdiction for the purchase of the LI3 Shares; (b) any foreign exchange restrictions applicable to such purchase; (c) any governmental or other consents that Lacus may need to obtain; and (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the LI3 Shares. Lacus’s subscription and payment for, and its continued beneficial ownership of the LI3 Shares, will not violate any applicable securities or other laws of Lacus’s jurisdiction.

(v)

Lacus represents that neither it nor, to its knowledge, any Person or entity controlling, controlled by or under common control with it, nor any Person having a beneficial interest in it, nor any Person on whose behalf Lacus is acting: (i) is a Person listed in the Annex to Executive Order No. 13224 (2001) issued by the President of the United States (Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism); (ii) is named on the List of Specially Designated Nationals and Blocked Persons maintained by the U.S. Office of Foreign Assets Control; (iii) is a non-U.S. shell bank or is providing banking services indirectly to a non-U.S. shell bank; (iv) is a senior non-U.S. political figure or an immediate family member or close associate of such figure; or (v) is otherwise prohibited from investing in LI3 pursuant to applicable U.S. anti-money laundering, anti-terrorist and asset control laws, regulations, rules or orders (categories (i) through (v), each a “Prohibited Lacus”). Lacus agrees to provide LI3, promptly upon request, all information that is reasonably necessary or appropriate to comply with applicable U.S. anti-money laundering, anti-terrorist and asset control laws, regulations, rules and orders. Lacus consents to the disclosure to U.S. regulators and law enforcement authorities by LI3 and its affiliates and agents of such information about Lacus as is reasonably necessary or appropriate to comply with applicable U.S. anti-money-laundering, anti-terrorist and asset control laws, regulations, rules and orders. Lacus acknowledges that if, following its investment in LI3, LI3 reasonably believes that Lacus is a Prohibited Lacus or is otherwise engaged in suspicious activity or refuses to promptly provide information that LI3 requests, LI3 has the right or may be obligated to prohibit additional investments, segregate the assets constituting the investment in accordance with applicable regulations or immediately require Lacus to transfer the shares of Common Stock. Lacus further acknowledges that Lacus will have no claim against LI3 or any of its affiliates or agents for any form of damages as a result of any of the foregoing actions.

(vi)

Lacus realizes that because of the inherently speculative nature of business activities and investments of the kind contemplated by LI3, LI3’s financial position and results of operations may be expected to fluctuate from period to period and will, generally, involve a high degree of financial and market risk that can result in substantial or, at times, even total loss of the value of the LI3 Shares.

(vii)

Lacus acknowledges and agrees that LI3 is a “shell company” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Pursuant to Rule 144(i) under the Securities Act, securities issued by a current or former shell company (such as the LI3 Shares) that otherwise meet the holding period and other requirements of Rule 144 nevertheless cannot be sold in reliance on Rule 144 until one year after the date on which LI3 files current “Form 10 information” (as defined in Rule 144(i)) with the SEC reflecting that it ceased being a shell company, and provided that at the time of a proposed sale pursuant to Rule 144, the issuer is subject to the reporting requirements of section 13 or 15(d) of the Exchange Act and has filed all reports and other materials required to be filed by section 13 or 15(d) of the Exchange Act, as applicable, during the preceding 12 months (or for such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports. As a result, the restrictive legends on certificates for the LI3 Shares set forth below cannot be removed except in connection with an actual sale meeting the foregoing requirements.

Any damages to the assets or business of the Indemnified Party caused by a failure by the Indemnifying Party to defend, compromise, or settle a Claim in a reasonable and expeditious manner requested by the Indemnified Party, after the Indemnifying Party has given notice that it will assume control of the defence, compromise, or settlement of the matter, shall be included in the damages for which the Indemnifying Party shall be obligated to indemnify the Indemnified Party.
