The usufruct rights granted to MDA for mining of the SALAR mining claims shall provide for a term of twenty (20) years for mining, extraction and exploitation, commencing with the START-UP DATE, conditioned to the effective starting-up of the industrial exploitation.

Once the above described term of usufruct has elapsed, MDA shall have an irrevocable option to a new usufruct for another twenty (20) years under the same terms and conditions as agreed herein. Said option shall be notified to DGFM in an authentic manner and must be exercised by MDA as from the elapsement of the initial term of twenty (20) years and until one (1) year thereafter.

Until MDA exercises the above mentioned option, it shall remain in the full and legitimate use and enjoyment of the mining claims, being understood that it will remain so under the same terms and conditions as provided therein but authorized during the interim period as Entrepreneur of a Percentage Exploitation Contract pursuant to Article 364 of the Argentine Mining Code.

Once the option has been exercised, the period of time during which MDA has acted as Entrepreneur of a Percentage Exploitation Contract will be deducted from the term of the new usufruct. If the irrevocable option is exercised by MDA but a legal impossibility arised which prevents the parties from entering into a new usufruct for a period of twenty (20) years, MDA will nevertheless remain for that twenty (20) year period in the full use and enjoyment of the mining properties and Entrepreneur of a Percentage

Exploitation Contract pursuant to Article 364 of the Argentine Mining Code and under the same terms and conditions as established herein. In such a case, the twenty (20) year term of the Percentage Exploitation Contract will be counted as from the elapsement of the initial term of the usufruct.

Ten (10) years before the end of the second period of twenty (20) years, the parties shall commence with negotiations aimed to obtain a new agreement for a third period of twenty (20) years, under the form of an usufruct or a percentage exploitation contract, as it may be convenient and under terms and conditions to be agreed upon by them.

DGFM and/or the PROVINCE as applicable, shall be responsible for the cost of said visits.

ARTICLE 19

The value of monthly net sales shall be specifically calculated on the basis of NET SALES VALUE as defined in Articles 19.2. and 19.3. below.

The participation percentage and the mining royalty will be calculated by multiplying the NET SALE VALUE per kilogram, as defined in 19.2. and 19.3, by the actual sales volume, expressed in kilograms, to which all those deliveries foreseen under 19.13 shall be added subject to 19.6. The resulting value shall be multiplied by the participation percentage rate and by the mining royalty, respectively, as participation and mining royalty. The Provincial mining royalty shall be adjusted as provided in Article 19.9 below.

given amount of the lithium end product, as specified in the conversion table attached as Annex V. The BASE PRICE shall consist of the higher of either: (a) the actual ex-factory F.O.B. invoice price; or (b) the respective international market price for comparable lithium carbonate produced from lithium brines adjusted ex-factory F.O.B., which the parties recognize to be the average of the “Valor” and “Valor Retorno” prices of shipments for the most recent month of Chilean lithium carbonate as reported in the most recent CARTAMIN edition, a monthly publication of Revista Mineria Chilena (Perez Valenzuela 1098, Of. 98, Providencia 9, Santiago, Chile) a sample copy of which is attached hereto as Annex VI; this average price shall be calculated at the average of the average “Valor” price (value of total “Valor” shipments divided by the corresponding total “Cantidad”) and the average “Valor Retorno” price (value of total “Valor Retorno” shipments divided by the corresponding total “Cantidad” ) for the respective month. Should CARTAMIN cease publication the parties shall mutually agree to a substitute publication source reporting comparable prices for lithium carbonate produced from lithium brines.

If no publication is available containing the effective price for the date of each invoice, the last available publication will be taken. Once the applicable one is published, then an adjustment will be made in order to calculate and pay the percentage participation and mining royalty.

With the purpose of determining the BASE PRICE defined in this Article, as well as its application to the cases under 19.6. and 19.8 of this Agreement, all foreign currencies shall be converted into United States dollars. For such purpose the cash rate of exchange offered by Citibank for each currency on the New York exchange market, on the latest exchange working day of each month, shall apply. The Buenos Aires branch of said Bank shall be able to certify the above mentioned exchange rates. In case some currency were not quoted on said date, at said bank on the New York exchange market, the quotation at the Argentine Branch of said bank, for the Buenos Aires exchange market, shall apply. Should Citibank cease its operations, the parties, by mutual agreement, shall designate for purpose of this paragraph, another U.S. Bank with branch in Argentina.

NET SALES VALUE shall be the BASE PRICE after deduction of sales returns, export taxes, internal taxes that integrate the sales price, value-added tax exposed on MDA’s invoice, or any other tax that may substitute or complement them in the future, that would have been effectively paid, and any other tax of analogous nature to the abovementioned ones, to be created in the future and imposed on said sales.

NET SALES VALUE for non-lithium products shall be the NON-LITHIUM PRODUCT BASE PRICE after deduction of sales returns, export taxes, internal taxes that integrate the sales price, value-added tax exposed on MDA’s invoice, or any other tax that may substitute or complement them in the future, that would have been effectively paid, and any other tax of analogous nature to the abovementioned ones, to be created in the future and imposed on said sales.

EXAMPLE: Assuming a yearly production of 15,000 Metric Tons CE’s with an average NET SALES VALUE of 2,500 US$/Metric Ton

The amount of participation percentages and the mining royalties to be paid hereunder on all sales from production coming from the areas outside those mining properties indicated in Annex I shall be based upon the accumulated sales in the calendar year a fraction thereof computed according to the following SCHEDULE II.

It is established that the Mining Royalty Rates specified in this Article, are in full satisfaction of the Provincial Law N^o 4.422 on Mining Royalties and its modifying Provincial Law N^o 4.512, and any other provincial Law that may substitute or modify them in the future. The parties agree that for practical reasons and contrary to what is established by Laws N^o 4.422 and N^o 4.512 where the mining royalty is levied on the physical volume of the mineral extracted, the mining royalty agreed hereunder shall be calculated and paid by FMC/MDA to the PROVINCE on the basis of the NET SALES VALUE of all products sold.

To such purpose, the total NET SALES VALUE for each month shall be converted, for each one of these months, to United States dollars (us$) utilizing the procedure defined under 19.2. The average of the NET SALES VALUE to apply in the calculation of the adjusted payment for the twelfth (12) month of each one of these five (5) years, as above foreeseen, shall be the quotient between total NET SALES VALUE of each year expressed in United States dollars (us$) and the total of the respective sales volumes expressed in kilograms.

The interest for late payment, shall be calculated upon the participation percentage and/or the mining royalty that would not have been paid in time and over the term of the delay, in a percentage consisting of the sum of the prime rate effective on the starting date of the delay quoted by Citibank plus fifty percent (50%) of that rate. The Argentine Branch of Citibank shall be able to certify the quoted rate. Should Citibank cease its operations, the parties by mutual agreement, shall designate for purpose of this paragraph, another U.S. Bank with branch in Argentina.

Any payment effectuated shall be applied to satisfy first the accrued late payment interests and secondly, to cancel, to the extent possible, the participation percentage account and/or mining royalty.

In case the delay should exceed the term on one (1) year, DGFM/The PROVINCE shall be entitled to exercise their right to rescind this Agreement, in accordance with Article 1204 of the Civil Code of the Argentine Republic. In such case, said Article shall be of strict application and the term to require compliance shall be fifteen (15) days.

The PROVINCE grants to FMC/MDA and this Agreement the stabilization of all taxes and mining royalties that FMC or MDA, as applicable shall pay to the Province of Catamarca and to the Municipality of Antofagasta de la Sierra and/or any subdivision of same that may be created in the future and to any department or delegation that form the Administration of the Province of Catamarca (hereafter referred to as the “Provincial Governments”). This means that FMC/MDA shall not pay to the Provincial Governments any total

amount as taxes and mining royalties in excess of the total amount which would be deemed as owed when calculated utilizing the taxes and the rates and the bases, and the mining royalty and the base as shown in Annex VIII. Any changes in taxes payable for any reason, including but not limited to, the introduction of new taxes, changes in tax rates, changes in the computation of the bases upon which the tax rates are applied, and any allowances of fiscal credits in arriving at a final tax liability to the Provincial Governments, that were imposed by laws, decrees, resolutions, or dispositions in general, issued by the authorities of the Provincial Governments shall results in a modification of the mining royalties payable under 19.5¹ in the manner set forth in this Article 19.9. Such mining royalties shall be reduced or increased in an amount as is necessary to equate total payments of taxes plus total mining royalties to the sum of (l) the total of taxes due under the taxes, the rates and the bases established in Annex VIII, and (2) the total Provincial mining royalty payable under Article 19.5² of this Agreement, as expressed in Argentine currency under the provisions of Article 19.4. The PROVINCE acknowledges that Annex VIII is complete in its entirety as to the agreed taxes applicable to FMC/MDA, based on taxes in effect on the date of execution of this Agreement. In order to determine the amount of any adjustment to the Provincial mining royalty under this Article it will be necessary to make two computations for each and every tax.

The first computation will be under the laws, decrees, resolutions, dispositions, regulations, or other authoritative rules pertaining to the computation of each tax in effect on the date of execution of this Agreement. The second computation will be under the laws, decrees, resolutions, dispositions, regulations, or other authoritative rules pertaining to the computation of that same tax in effect for the period for which the tax liability is being computed. If the second computation results in a greater total tax liability than does the first computation, there will be a reduction in the Provincial mining royalty due under Article 19.5 equal to this difference between the first and second computations of the tax. If the second computation results in a lesser tax liability than does the first computation, there will be an increase in the Provincial mining royalty due under Article 19.5³ equal to this difference between the first and second computation of the tax.

The adjustment to the Provincial mining royalty required by this Article shall take place with the next Provincial mining royalty due immediately after the filing due date of the report or return upon which the tax liability is reported to the Provincial Governments. If, as a result of the adjustment required by this provision, a reduction in the Provincial mining royalty is greater than the total amount due for the next Provincial mining royalty, all immediately following Provincial mining royalty payments due shall be reduced in order of first occurance until the total adjustment has been made.

In order to maintain the value of the adjustment (increase or decrease of assessments with respect to the ones in force on the date of execution of this Agreement) said adjustment, in Argentine currency, will be converted to us$ dollars at the official rate of exchange applicable to export payments (drafts and transfers to foreign countries) prevailing at the Banco de la Nación Argentina on the last working day before the date on which the calculation is made. In order to offset the adjustment with the mining royalties, the amount in (us$) United States Dollars resulting from the application of the procedure indicated in the preceding paragraph shall be converted to Argentine currency at the official rate of exchange indicated above, prevailing on the last working day before the date or dates on which the actual increase or decrease of the mining royalties is made. The parties agree that any tax, charge, fee, duty or assessment imposed on the extraction and/or transportation of minerals outside or within the Municipality of Antofagasta de la Sierra and/or the Province of Catamarca shall be deducted from the Provincial mining royalty provided in this Agreement.

The obtention or expiry of Provincial benefits of any sort originated in promotional regimes, will have no incidence whatsoever upon the participation percentages, mining royalties and taxes to be paid by FMC/MDA to DGFM and the PROVINCE, respectively.

ARTICLE 20: FMC or MDA, as the case may be, undertake to supply the needs of the Argentine domestic market for the consumption of all the products they manufacture.
