FIRST: General Background.

By deed dated January 31, 1986, executed before the Notary Public of Santiago Mr. ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, Amax, Molymet and ▇▇▇▇▇ entered into the Agreement for the Salar de Atacama Project and its various annexes. Likewise, by deed of the same date and notary, Amax, Molymet and ▇▇▇▇▇ formed the limited liability company named Sociedad Minera Salar de Atacama Limitada. Subsequently, a lease agreement was entered into between CORFO and Minsal, by public deed dated April 18, 1986 before the Notary Public Mr. ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, whereby ▇▇▇▇▇ leased to said company, of which it was a partner, the usufruct of certain OMA mining properties, for the development of the project agreed in the Agreement for the Salar de Atacama Project. Furthermore, on December 14, 1992, by deed granted on that date and before the Notary Public of Santiago ▇▇. ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇, Amax, with the express and irrevocable consent of the other partners of Minsal, sold, assigned and transferred to Amsalar, who bought, accepted and acquired for itself each and every one of the rights and corporate interests of the former in said company. Then, by public deed dated November 12, 1993, granted before the Notary ▇▇▇▇ ▇▇▇▇▇▇▇ San ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, the companies Amsalar and Molymet sold, assigned and transferred all of their corporate rights in Minsal to SQMK, leaving SQMK and CORFO as the sole partners of Minsal. On November 12, 1993, by public deed before the Notary Public of Santiago, ▇▇. ▇▇▇▇ ▇▇▇▇▇▇▇

SQM - Corfo Lease Agreement

▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, the agreement between CORFO and Minsal was executed, nullifying the previous lease agreement executed between the same parties in 1986. On the same date and before the same notary, the Project Agreement was executed between CORFO and SQMK, nullifying the 1986 agreement of the same name. The purpose of the Project Agreement was for Minsal to develop the Project to produce and commercialize any and all potassium, boron, lithium and sodium compounds, and, in particular, potassium or potassium salts, boric acid, lithium, lithium products, sodium chloride, potassium chloride, sodium sulfate, potassium sulfate and any derivative or compound thereof and any other mineral substances economically recoverable from one or more brines, aquifers, land, mining properties and other relevant assets and rights within the commune of San ▇▇▇▇▇ de Atacama, and especially within the leased OMA properties. By public deed dated August 8, 1994, Minsal was modified and converted into Sociedad Minera Salar de Atacama S.A., today the Company. Subsequently, on December 19, 1995, the Project Agreement was modified before the notary public of Santiago, ▇▇. ▇▇▇▇ ▇▇▇▇▇▇▇ San ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and on December 21, 1995, before the same notary, the Project Agreement was again modified. Finally, by public deed of the same date and before the same notary, the Parties amended the Agreement. On December 28, 1995, following a capital increase carried out the previous year, ▇▇▇▇▇ sold its interest in the Company. By deed dated November 29, 2012, the Company executed a unilateral agent declaration, whereby it transferred to CORFO the ▇▇▇ and Salar Properties, which had been established by the Company in the area comprising the Properties.

SECOND: Considerations.

The Parties expressly state that they have taken into special consideration for the purposes of agreeing on the modification and setting of the consolidated text of this Agreement and the Project Agreement, the following:

2.1.

The Agreement and the Project Agreement are related contracts, intimately linked to each other, which have bound and bind all those party to them, that is, the Companies and CORFO.

2.2.

The development of the lithium industry is of relevant importance for the State of Chile, given that it possesses one of the world’s largest reserves of this mineral, whose sustainable exploitation means significant economic benefits and income for Chile, and, in addition, to become a significant contribution in the development of the industry associated with this mineral, especially of batteries and storage devices. For this reason, it must generate adequate conditions to enable its active participation in the expansion of the lithium market in the coming years and its positioning as a relevant player in the exploitation of lithium in the long term.

2.3.

Both for the aforementioned purposes and to generate the right conditions and incentives to encourage investment, innovation and increased levels of lithium exploitation in the coming years, it is necessary to improve and update the Agreement and the Project Agreement in order to increase the Company’s lithium production and commercialization quota within the term of such contracts, establishing norms that ensure an efficient and sustainable exploitation subject to strict environmental protection standards, with the understanding that the Salar de Atacama is a basin whose aquifer systems are interconnected, and also best practices of compliance and

SQM - Corfo Lease Agreement

corporate governance, and that regulate the timeliness and completeness of the information that the Companies must provide to CORFO to best comply with the Agreement and the Project Agreement.

2.4.

Likewise, it was deemed necessary to establish a new mechanism for calculating the Rent, which contemplates rates by price range to be applied to the price actually paid by the final consumer or unrelated third party. In order to safeguard this last principle, the Company must additionally make reasonable efforts to comply with the tax regulations that refer to advance price agreements that include lithium and potassium products.

2.5.

On the other hand, the need to create conditions to favor the development in our country of an industry of lithium products with greater added value was taken into account, for which purpose the granting of preferential lithium prices by the Company to Specialized Producers that manufacture such value-added products from lithium inputs extracted from the Properties in Chile is regulated.

2.6.

The sustainable development of economic activity in the Salar de Atacama and its surroundings is a priority objective of CORFO, for which it is essential that the Company commit to maintaining high standards of corporate social responsibility and practices of relationship and dialogue with the communities, especially with regard to possible environmental and social impacts of the Company’s activities in the area of influence of its operations in the Salar de Atacama, both in the communities and in the urban areas where it manufactures its products.

2.7.

Finally, shared value mechanisms were implemented with the local communities neighboring the Salar de Atacama, obligating the Company to provide contributions for research and development of the lithium industry and complementary industries.

THIRD: Ownership of the Properties, Lease and Project.

▇▇▇▇▇ owns, among other mining properties, the Properties, on which the Project has been developed since 1983. This, with the essential purpose of being able to produce and commercialize all and any compound of potassium, boron, lithium and sodium and, in particular, potassium or potassium salts, boric acid, lithium, lithium products, sodium chloride, potassium chloride, sodium sulfate, potassium sulfate, and any derivative or compound thereof, and any other mineral substances economically recoverable from one or more brines, aquifers, soils, mining properties and other relevant assets or rights that are located or formed within the limits of the commune of San ▇▇▇▇▇ de Atacama, Province of El Loa, Region of Antofagasta, Republic of Chile. In this context and as mentioned above, in 1993 ▇▇▇▇▇ entered into the Project Agreement with SQMK and SQM, as well as the Lease Agreement for certain OMA mining properties with Minsal, which is still in force, whereby CORFO leased and granted to the Company the exclusive right to exploit 16,384 OMA mining properties. The Properties are valid, with their mining concession fees up to date and duly paid, registered on page 408 number 11 of the year 1977, on page 131 and the following pages, number 6 of the year 1979, and on page 62 number 15 of the year 1984, all of the Mining Property Register of the Custodian of Mines of El Loa, re-registered on page 926, number 248 of the Mining Property Register of the Custodian of Mines of Calama,

The lease agreement is registered under number 127 of page 239 dated November 30, 1993 of the Registry of Mortgages and Encumbrances of the Calama Mining Registry. The properties are also subject to the prohibition, registered on page 114, number 85 dated November 30, 1993, that CORFO will not carry out or permit any exploration, exploitation or mining, aquifer or industrial work of any type or kind itself or through third parties on any of the properties owned by it; and to the prohibition registered on page 116, number 86 dated November 30, 1993, by which CORFO agreed not to carry out or permit any exploration, exploitation or mining, aquifer or industrial work of any type or kind itself or through third parties on all of the 1,370 OMA mining properties that are property of CORFO and referred to in Annex 1 and in the attached plan annex number 2, added with the number 4 at the end of the Registry of Prohibitions of the year 1993 in the Calama Mining Registry. ▇▇▇▇▇ also owns the ▇▇▇ and Salar Properties, which are located within the perimeter of the Properties and identified in the Second Transitory Clause.

The Company will determine the amount of the Rent corresponding to each Rent Period, in Dollars and its value will be paid in its equivalent in Chilean pesos, according to the observed exchange rate in effect on the day the payment is made as certified by the Central Bank of Chile. The Company shall deliver to CORFO proof of the electronic bank transfer or bank deposit corresponding to each Rent Period, together with a payment or settlement statement and all the respective Rent calculation information, in systematized form and in digital format, including the supporting background information on which such payment or settlement statement is based, with all the background information referred to in the Fourteenth Clause (Access to Information by CORFO), duly updated as of that date. It shall be the Company’s obligation to maintain an updated information platform that CORFO will use for such purpose.

(e)

In the event of delinquency or simple delay in the payment of the Rent, it will accrue penal interest on a daily basis, from the date of delinquency or simple delay until the date of actual payment, equivalent to the maximum standard rate allowed to be provided for credit transactions of money in non-adjustable national currency of more than 90 days, at the rate in force on the date of delinquency or simple delay, or on the date of actual payment, at CORFO’s election.

SQM - Corfo Lease Agreement

(f)

In the event that after the payment of the Rent, CORFO detects minor differences or obvious calculation errors in the computation of the Rent or requires further background and/or information, it will communicate this to the Company by means of a written communication, stating the reasons on which the claim is based and/or the amount of the differences detected. In the event that the Company agrees with ▇▇▇▇▇’s claim, the Company will have a period of 10 Business Days to resolve it, either by paying the difference and/or providing CORFO with further background and/or information.

(g)

Notwithstanding the foregoing, CORFO shall have the right to contest any Rent payment settlement. For such purposes, ▇▇▇▇▇ shall inform the Company in writing, stating the reasons on which it is based and the amount of the differences detected. In this case, the issuance of the invoice by ▇▇▇▇▇ and the receipt and collection of the Rent shall not constitute acceptance by CORFO. The sending of such letter will give rise to the following procedure (the “Appeals Procedure”):

(i)

The Company will have a period of 15 Business Days to send to CORFO the background information justifying the settlement, rejecting CORFO’s position, or to pay such differences.

(ii)

If such background information is not sufficient in ▇▇▇▇▇’s opinion or if the Company does not agree with ▇▇▇▇▇’s position, ▇▇▇▇▇ shall propose to the Company a list of 3 first level independent experts and/or auditors operating in Chile and independent of both parties, from which the Company shall select one of them within 5 Business Days after receiving the list. If the Company does not do so within that term, CORFO shall select and directly contract the services of such auditing firm or expert. The independent expert and/or auditor shall be entitled to request from the Company and/or CORFO all the information it deems necessary, which must be provided by the Company and/or CORFO within 10 Business Days. The review of the Rent shall conclude with a final report to be delivered by the independent expert and/or auditor to both Parties within a term not to exceed 60 calendar days, extendable by the Parties, counted from the date of acceptance of the appointment, and which shall determine the correct calculation of the Rent. Any adjustment resulting from the decision of the Expert and/or independent auditor shall be included in the settlement for the next quarter. This is subject to the right of the parties to appeal to the Arbitral Tribunal. If there is a difference in favor of CORFO, the Company shall pay it with the current interest for credit transactions of non-adjustable money in local currency, from the date of the settlement presented by the Company until the date of the actual payment of such difference. It shall also pay CORFO the cost of the independent expert and/or auditor, unless ▇▇▇▇▇’s position is completely rejected.

SQM - Corfo Lease Agreement

(iii)

If any of the Parties does not agree with the report of the independent expert and/or auditor, and only after its conclusion, such Party may resort to the arbitration provided for in this Agreement for the correct determination of the Rent. If the Arbitral Tribunal determines that the Rent payment made by the Company was less than the amount due, the Company shall pay the difference, for all the Rent Periods affected by such insufficiency, plus interest equivalent to the maximum standard rate allowed to be provided for credit transactions of money in non-adjustable national currency of more than 90 days, at the rate in force between the date on which the payment should have been made or the date of its actual payment, at CORFO’s election. In addition, the Company shall pay in full the cost of the independent expert and/or auditor and the costs of the arbitration. If, on the other hand, the Arbitral Tribunal determines that the Rent payment made by the Company pursuant to the review of the Rent was equal to or greater than that due, CORFO shall reimburse the Company for any excess amount paid, duly adjusted, in the following quarter’s payment, and the payment of the costs of the arbitration.

(iv)

If within a period of 3 consecutive years, the Company is sentenced by the Arbitral Tribunal on 2 occasions to pay to CORFO differences in the calculation and payment of Rent, in the second arbitration trial the Company agrees to pay in favor of ▇▇▇▇▇, both the difference in Rent determined by the judgement and the interest accrued in the manner set forth in Section 7.3(e)and the costs of such arbitration process. Likewise, and as a penalty and as an anticipated assessment of the damages, the Company agrees to additionally pay a fine equal to the amount of such difference.

(h)

Unless otherwise agreed, the Parties agree that in the event that the Company decides to carry out the exploitation of Other Products and Other Lithium Products (other than those intended to be converted into Lithium Products), it shall pay provisionally and for a maximum of 3 Payment Periods, a Rent equal to 10% calculated on the basis of the sales price, according to the Rent calculation mechanism in Annex 6. Before the expiration of the 3 Payment Periods, the Company shall negotiate in good faith with CORFO the definitive rate or range of rates on which the Rent shall be calculated, for which purpose the Company shall provide CORFO with all the technical and economic background information related to the new product, in accordance with the information required for such purposes in this Agreement. If no agreement is reached, the Rent shall be determined by an independent expert and/or auditor, in accordance with the provisions of the appeals procedure, as applicable.

(i)

Sales of moist, unfinished potassium chloride, based on its degree of processing required for international markets, which are carried out between the Company and its Related Parties for conversion to other products, shall be subject to the corresponding rate according to the price range as established in

SQM - Corfo Lease Agreement

Annex 5, using for such purpose 81% of the average sales price of Potassium Chloride, finished product, to an unrelated end customer in the respective Rent Period.

EIGHTH: Product Traceability.

The Company undertakes, by the first Anniversary, to implement the necessary mechanisms to guarantee CORFO comprehensive traceability of the lithium products through the identification of the batch number and quantity determined at the chemical plant, which must be reflected in all sales invoices of the Company, as well as in the sales invoices of SQM and its Related Parties to the end customer. For all other products other than lithium products, it will be presumed that they are products derived from the Properties, unless the Company proves their acquisition from third parties through its accounting documentation.

NINTH: Operating Commitment and Minimum Guaranteed Income.

If during any calendar year beginning from the Commencement Date, the Company sells a quantity of tons less than 60% of the sum of (i) 66 kMt plus (ii) the Expansion 1 Capacity (the “Minimum Operating Capacity for Guaranteed Payment”), as indicated in Annex 9, for any reason other than a Force Majeure Event, the Company will pay to CORFO, within the first quarter of the calendar year following such year, additional rent until reaching such quantity of tons equivalent to the percentage indicated above.

TENTH: Restitution, Transfer and Acquisition Right.

10.1.

At the end of the Term of the Agreement, the following obligations, rights and options shall become due:

(a)

The Company shall return to CORFO all that personal property and real estate that it delivered to the Company by virtue of the Project Agreement, and, among others, the Assets Subject to Restitution, within a period of 3 months from the termination or dissolution referred to above;

(b)

Within the last 6 months of the Term of the Agreement or the 6 months after its termination, CORFO shall have the irrevocable option to purchase all or part of the water use rights that SQM, the Company or any of its Related Parties currently owns or in the future would acquire or establish, that benefit or are necessary for the exploitation, either currently or in the future, of the Properties, and that are located outside the perimeter of the Properties. For the exercise of this option, the Company and its Related Parties shall make available to CORFO an amount of water rights equivalent to the greater of the following alternatives: (x) 240 liters per second as indicated in the RCA currently in force; (y) the maximum quarterly flow used by the Company in the operation of the Project during the last 5 years of the Term of the Agreement; and (z) the maximum flow indicated in the RCA(s) in force at the time of the termination of the Term of the Agreement. The acquisition price shall be the one agreed by the Parties, and if such agreement is not possible, the price determined by an independent and internationally recognized

SQM - Corfo Lease Agreement

appraiser, appointed by mutual agreement between the Parties or, failing such agreement within 10 business days, by the Arbitral Tribunal, which shall be constituted for the sole purpose of appointing the appraiser. The intervention of the Arbitral Tribunal in the appointment of the appraiser shall not disqualify its members from hearing disputes arising from the determination of the price. The price of the option shall be calculated considering the value of such assets in the market of the Antofagasta Region. The Company shall safeguard with due diligence the ownership of such rights and assets, and shall be subject to a prohibition to enter into acts or contracts without the prior written consent of CORFO. CORFO shall be entitled to transfer its rights to this purchase option to third parties, which shall include the acceptance by the acquirer of the stipulations set forth in this Clause and the Twenty-Fifth Clause (Dispute Resolution and Arbitration).

(c)

The Company or its Related Parties shall transfer to CORFO free of charge all the easements, whether they are mining or of any other nature, that benefit the Properties and/or the Project, regardless of the location. This obligation does not apply to mining easements established in the Salar del ▇▇▇▇▇▇.

Such assets shall be inventoried for these purposes prior to the end of the Term of the Agreement. For the purposes of determining the value of those assets that are not land, this shall be equivalent to the replacement value, considering their economic depreciation (the “Replacement Value”). For purposes of determining the purchase value of land, if any, this will be calculated considering the value of such assets in the market of the Antofagasta Region for non-agricultural rural areas. In no case will these assets be valued as essential going concern assets. The Acquisition Right may be exercised by CORFO within 6 months prior to the end of the Term of the Agreement or 6 months after the end of the Term of the Agreement. If the Parties do not agree on the Replacement Value or the value of the land, within 60 Business Days of the exercise of the right by CORFO, it shall be determined by an independent and internationally recognized appraiser, appointed by mutual agreement between the Parties or, failing such agreement within 10 Business

SQM - Corfo Lease Agreement

Days, by the Arbitral Tribunal, which shall be constituted for the sole purpose of appointing the appraiser. The intervention of the Arbitral Tribunal in the appointment of the appraiser shall not disqualify its members from hearing disputes arising from the determination of the price. ▇▇▇▇▇’s Acquisition Right may be transferred to third parties, which transfer shall include the acceptance by the acquirer of the stipulations set forth in this Clause and the Twenty-Fifth Clause (Dispute Resolution and Arbitration).

(e)

Within the last 6 months of the Term of the Agreement or within 6 months after its termination, CORFO shall have the right to purchase the mining concessions that the Company or any Related Party to it currently holds or may hold in the future on the surface included within Protection Ring 2, in which case, CORFO shall pay the effective and accredited value that the Company or its Related Parties have reasonably incurred in establishing, defending and protecting such mining concessions, which value shall be duly audited and validated by an independent external auditor. SQM declares that it holds mining concessions in Protection Ring 2, which are indicated in Annex 3. The Company shall safeguard with due diligence the ownership of such rights and assets, and shall be subject to a prohibition to enter into acts or contracts without the prior written consent of CORFO. In the event that CORFO and/or the third-party holder of the purchase option right do not exercise it, the Companies and any of its Related Parties are obliged not to extract brine in the referred Protection Ring 2 for a period of 15 years from the termination of the ▇▇▇▇▇▇▇▇▇.▇▇ the event that CORFO and/or the third-party holder of the purchase option right exercises such option, they may not extract brine in Protection Ring 2. If the option is transferred to a third party, the third party must accept the stipulations set forth in this Clause and the Twenty-Fifth Clause (Dispute Resolution and Arbitration).

(f)

The transfer of title to the assets covered by the options in Sections 10.1(b), 10.1(d) and 10.1(e) shall be effected within 90 days of the exercise of the options. The transfer of the assets referred to in Sections 10.1(a) and 10.1(c) shall be effected at the time of termination of the Agreement. In any event, the assets to which these options and rights relate must be acquired and paid for by the acquirer in cash within 180 days after their price has been determined and the acquirer shall not be entitled to take possession of them or exploit them until the price has been fully and finally paid, if any, and the Agreement has been terminated.

(g)

At the end of the Term of the Agreement, the totality of the brines, salts in ponds, harvested salts, salt stockpile, and any other product or material extracted, whether in process or as a finished product, discard or waste, that

SQM - Corfo Lease Agreement

remain in the Salar de Atacama, will be the exclusive domain and property of CORFO.

10.2.

At the end of the Term of the Agreement, CORFO shall have the right to demand the payment of rent for finished products of extracted material at that date, which are pending sale and outside the Properties, which the Company shall duly inform CORFO for such purposes. Such rents shall be paid in full to CORFO within 6 months from the termination of the Agreement, whether or not such products have been sold. In the latter case, the rent shall be paid to CORFO based on the sale prices of the products of the last quarter of the Term of the Agreement.

10.3.

Once the Agreement has ended, the Parties shall have a term of 3 months for the purpose of carrying out the material delivery of the facilities and other assets subject to this Clause, with due regard to the terms established for exercising the different purchase options referred to in this Clause. During such period the Company shall remain responsible for them, and shall deliver the mining properties and other assets free of any occupant. In turn, the Company shall have a term of 12 months to remove all the elements, equipment and installations that it has added or constructed on the Properties that are not Assets Subject to Restitution or the object of the Acquisition Right, as indicated in the inventory to be made for these purposes, without such removal constituting an obligation for the Company. The aforementioned items, equipment and facilities that are not withdrawn by the Company within the aforementioned term, shall pass by right to CORFO’s ownership and shall thereafter be under its exclusive and total control. The Company shall make reasonable efforts so that the removal of the aforementioned assets does not hinder the new operation.

(e)

Agree directly or indirectly, with the other operators of the OMA belongings of the Salar de Atacama, without prior authorization from CORFO, ways of operating that mean a joint or integrated operation of both operations; so that its operation is always independent and that there is no facilitation of operational information, business strategies, information systems or common applications and/or people conventions or pacts that represent price agreements and others that by their nature may adversely affect the Rent. This prohibition shall not extend to a possible environmental coordination and/or in the field of conducting joint hydrogeological studies or other commercial agreements that do not infringe upon such prohibition, for the better protection or understanding of the Salar de Atacama.

TWELFTH: Environmental Compliance.

The Company undertakes to comply with the final resolutions or instructions of the environmental authority or, if applicable, the environmental or ordinary courts, as appropriate, as well as comply with current environmental legislation and the respective RCAs, especially to comply with the compliance program or programs agreed upon by the Company and the SMA with their respective control mechanisms, which guarantee the sustainable management of the Salar. Likewise, the Company undertakes to develop and implement within a period of 18 months from the Commencement Date, a regular and continuous online monitoring information system that allows CORFO and its committees, the competent authorities and supervisory bodies to verify and have access to (i) online information that will be required instantaneously, which will be the one established for each system in the RCA(s), and which relate to continuous measurements of parameters, as well as other variables that allow for the visualization and/or anticipation of a water imbalance in the systems to be protected and (ii) other information that the RCAs need to communicate, which will be uploaded to the system with the frequency that such RCAs establish. Within 30 months from the start date and within the framework of the obligations under Section 16.6

SQM - Corfo Lease Agreement

of the Project Agreement, the Company will develop a system that allows sharing information of environmental relevance and community interest, which will feed the online information system referred to above. The latter system and its content shall be agreed between the Company and the Non-Metallic Mining Committee. In addition, the Company shall collaborate permanently by providing CORFO with the relevant studies that have been carried out to comply with the obligations imposed by the Agreement in this matter free of charge, and other technical, productive, geological, hydrogeological and environmental information that is necessary to adequately understand the information provided by regular monitoring, providing the necessary facilities so that CORFO has expeditious access to such information. CORFO and/or the committee designated by it, may carry out at its own cost environmental, hydrogeological, reserves, reinjection and/or strategic studies in the entire Salar de Atacama basin, for which the Company shall provide all the collaboration and support necessary for the development of such studies, as well as work together in the improvement of a sustainable environmental strategic model and integrated monitoring of the Salar, in which the Company shall participate jointly with CORFO and/or the designated committee. The Company will have the right to review the previous drafts of these studies, in order to have the possibility of including its comments in the reports before their publication to avoid possible errors that could be corrected in a timely manner in the final reports, in cases in which ▇▇▇▇▇ independently finds merit in the proposed correction. If the Company deems it appropriate, it may send its opinion on the final report to the Public-Private Council of the Non-Metallic Mining Committee, which will publish on its website the CORFO report and the Company’s opinion, as well as any opinion of third parties with an interest in the subject. In the handling of the information referred to in this Clause, CORFO shall be subject to the confidentiality obligations set forth in the Twenty-Third Clause (Confidentiality).

THIRTEENTH: CORFO Representatives.

13.1

The Parties agree that CORFO shall have representatives before the Company to supervise itself, or through third parties it may designate for such purpose, the performance of the Agreement. For this purpose, the Company, SQM and its Related Parties shall be obliged to safeguard and maintain the information that allows CORFO to easily identify the assets and sales related to the performance of the Agreement, and shall also provide all the documentation, information and commercial data that may be necessary for the aforementioned purpose. Subject to the Company’s confidentiality and security requirements, the representatives shall have the right to audit, make appraisals, take samples, examine, and make copies or extracts of exploration, exploitation, operating, production, financial and commercial records in any form that are stored, whether written, electronic or otherwise, in relation to this Agreement, that are in the possession or under the control of the Company, for the sole purpose of evaluating the Company’s compliance with the obligations set forth in this Agreement. Likewise, the Company, SQM and its Related Parties shall be obliged to provide and deliver to the Representatives all relevant information to verify compliance with the obligations of this Agreement, related to the consignment of products, tolling, joint venture, off-take and commercialization of all products subject to this Agreement, as well as all information related to or concerning the Properties, the ▇▇▇▇ Properties, the ▇▇▇ and Salar Mining Properties, and the Assets Subject to

SQM - Corfo Lease Agreement

Restitution, and in respect of which purchase options have been agreed upon, granting the necessary facilities and access to such information at the sole request of CORFO. The Company shall keep such records updated at all times during the Term of the Agreement and for a period of 3 years after its expiration.

13.2

The Company shall, at any time upon ▇▇▇▇▇’s request, make the records available for evaluation and audit as follows:

(a)

Such records shall be made available during business days and hours at the office of the Company or its facilities, subject to at least three Business Days’ prior written notice. Subject to reasonable confidentiality and security requirements, including prior coordination with the Company, CORFO shall have the authority to enter the Properties and the facilities and plants at any time for the purpose of reviewing and corroborating the information provided by the Company in the areas described above.

(b)

The costs of any audit performed under these provisions shall be borne by CORFO, unless as a result of the audit substantive information relating to fraud, misrepresentation or noncompliance by the Company is discovered, in which case CORFO may recover the relevant costs from the Company.

(c)

If as a result of the reviews carried out by CORFO any observations of any kind are generated, ▇▇▇▇▇ will inform the Company by means of a written communication, stating the reasons on which they are based. The sending of such letter will give rise to the application of the appeals procedure established in this Agreement, subject also to the provisions of the Twenty-Fifth Clause (Dispute Resolution and Arbitration), as applicable.

(d)

The Company shall provide the facilities for CORFO to implement such systems as it deems appropriate for the proper control of compliance with this Agreement, which, in any case, shall not interfere with the operation of the Company. Such obligations shall constitute a material obligation of this Agreement, to the extent that such obligations have a direct impact and a material effect on the performance of the obligations under this Agreement. ▇▇▇▇▇ shall communicate in writing to the Company the person or persons designated for such purposes at such time or times as it deems appropriate.

13.3

CORFO through its Representatives shall have the right to request from the Company and to access at a minimum the information indicated in the Fourteenth Clause (Access to Information by CORFO), which shall be maintained during the Term of the Agreement and for a period of 3 years after its expiration.

SQM - Corfo Lease Agreement

FOURTEENTH: Access to Information by ▇▇▇▇▇.

CORFO through its Representatives shall have the right to request from the Company and to access at a minimum the information contained in Annex 7.

FIFTEENTH: Preferential Price for Specialized Producers.

15.1.

In line with the efforts made by the State of Chile to attract industries that add value and produce higher value-added goods in the country, the Company agrees that during the entire term of the Agreement, and subject to CORFO’s approval in each case, it will offer its lithium products at the Preferential Price (the “Most Favorable Price Obligation”), to specialized producers, whether public or private, of value-added products including, among others, the production of lithium cathodes, lithium battery components and lithium salts, which carry out their production activities in Chile (“Specialized Producers”). For these purposes, the Preferential Price will be defined after CORFO communicates who these Specialized Producers are, and will consider the specifications and categories of the products and their volumes. Other conditions, such as payment and credit characteristics, if any, shall be negotiated between each Specialized Producer and the Company, under conditions equivalent to those agreed between the Company and other customers. Those companies established in Chile that have developed or acquired technology that allows them to develop value-added products, such as those already mentioned, based on what is produced by the Company by virtue of this Agreement, are considered Specialized Producers. Accordingly, in no case may the preferential sale be allocated by the Specialized Producers or their subsidiaries for the commercialization of products such as lithium carbonate, lithium hydroxide or lithium chloride in any of its grades.

15.2.

The Most Favorable Price Obligation may not initially exceed fifteen percent of the annual theoretical production capacity of lithium hydroxide and lithium carbonate products, as indicated in Annex 11. Once the aforementioned fifteen percent has been fully allocated, such percentage shall be increased in two point five percent increments annually until reaching twenty-five percent of the annual theoretical production capacity. To make this option effective, CORFO must indicate in writing the company or companies that qualify as Specialized Producers, at least one year prior to the start of these sales.

15.3.

The Most Favorable Price Obligation shall be formalized by means of a contract signed between the Company and each of the Specialized Producers. In such contract, the parties shall establish, at least, reciprocal rights and obligations, in particular, the Most Favorable Price Obligation of the Company and the obligation of the Specialized Producer to use the lithium products acquired from the Company only for the production of value-added products; the validity of the Most Favorable Price Obligation assumed by the Company in the Agreement, which can only be effective so long as the Specialized Producer status is maintained; the mechanisms for adjusting the percentage of lithium products subject to the Most Favorable Price Obligation, if applicable; and the guarantees to ensure compliance with the parties’ obligations, especially for compliance with the Most Favorable Price Obligation. The Company

SQM - Corfo Lease Agreement

will not assume liability for changes in the conditions or termination of the contract due to the qualification, changes or loss of the Specialized Producer status as determined by ▇▇▇▇▇. ▇▇▇▇▇ will not be a party to the aforementioned contract, nor will it have any liability for the failure to comply with the Most Favorable Price Obligation or any of the other obligations set forth in the aforementioned contract. However, given the public interest involved in the Most Favorable Price Obligation, CORFO may carry out actions aimed at supervising and verifying compliance with the obligations agreed to by the parties, which shall be expressly set forth in the contract signed by the Company and each Specialized Producer. For the foregoing, CORFO shall be notified of any failure to substantially comply with the contract entered into for these purposes between the Company and the Specialized Producers, whether total or partial, by the affected Specialized Producer or by the Company, as the case may be. The notification must be made in writing to CORFO, indicating the circumstances that constitute the total or partial breach of the obligations, and providing the background information on which it is based. CORFO, through the corresponding administrative act, may revoke or nullify the status of Specialized Producer, in cases it has been contemplated in the administrative act that they qualified as such.

15.4.

Likewise, the breach of the obligation to offer and provide the Most Favorable Price Obligation under the terms of this Clause, shall give rise to the payment of a fine or indemnity as a penalty clause in favor of CORFO, which the Parties assess in advance in the amount of 10 million Dollars. In turn, the breach of the Company’s obligation to comply with the Most Favorable Price Obligation to the Specialized Producer will give rise to the payment of a fine or indemnity as a penalty clause in favor of CORFO, which the Parties assess in advance in the amount equivalent to 3% of the amount of the breached transaction, all this, without prejudice to the liability of the Company towards the Specialized Producer. For the purposes of determining whether an obligation under this Clause has been breached, the Parties shall first resort to the mediation of the Contract Auditor, which shall be carried out within 90 days of being requested by either Party. Once the 90 days have elapsed, any of the Parties may turn to the Arbitral Tribunal. It shall be understood that the Company does not comply or partially complies with the Most Favorable Price Obligation, if at any time during the term of the agreement, it unjustifiably refuses to sell lithium products at the Preferential Price to the Specialized Producer, or unjustifiably sells to the Specialized Producer a percentage of lithium products less than that designated as subject to the Most Favorable Price Obligation. The Company shall identify and reclassify current exports of lithium products into battery grade lithium carbonate, technical grade lithium carbonate, battery grade lithium hydroxide, technical grade lithium hydroxide and other lithium products in order to facilitate the calculation of the Preferential Price. This work will be reported to the National Customs Service so that it will have specific information regarding each product category, so that, within the framework of its powers, the National Customs Service may develop proposals for improvements to the tariff classifications.

SQM - Corfo Lease Agreement

SIXTEENTH: Force Majeure.

Each Party shall be excused from the performance of its obligations in accordance with this Agreement to the extent such failure is due to a Force Majeure Event and for the duration of the Force Majeure Event, and the Party not affected by the Force Majeure Event shall continue to perform its obligations. The Party affected by a Force Majeure Event shall notify the other Party in writing of the occurrence of the Force Majeure Event within 72 hours of the occurrence of the event or as soon as reasonably possible.

SEVENTEENTH: Company’s Obligation of Boundary Marking.

The Company undertakes to construct, maintain, keep in place and replace at its own expense the boundary markers placed at the vertices of the Properties and the ▇▇▇▇ Properties. Consequently, it is the Company’s obligation to complete and maintain at its own expense the network of physical boundary markers for the entire perimeter of said Properties in accordance with the terms established in Article 118 of the Mining Code. Within a period of 1 year from the Commencement Date, the Company will construct and replace the pending milestones and boundaries at the vertices of the aforementioned appurtenances. For these purposes, to the extent necessary and as required by the Company, CORFO shall, at the request of the Company, grant and deliver such court orders as may be reasonably required by the Company to enable it to comply with this obligation.

EIGHTEENTH: Mandate and Provision of Accounts.

CORFO hereby delegates, grants and confers a broad and irrevocable special mandate or power of attorney to and in favor of the Company, which accepts and is interested in such and for the entire Term of the Agreement in order for the latter to assume the judicial and extrajudicial defense and effectively safeguard the subsistence and integrity, both legal and material, and the exclusive and exclusionary control of each and every one of the Properties, the ▇▇▇▇ Properties, the ▇▇▇ and Salar Properties and all other Assets Subject to Restitution.

The External Auditors will be proposed by ▇▇▇▇▇ through a list of three candidates, and appointed by the Company. If the Company does not select the External Auditors within 10 Business Days of the presentation of the list of three, CORFO must present a second list of three. If the Company does not select the External Auditors within the same period, the appointment shall be made by the Arbitral Tribunal. The External Auditors shall be paid by CORFO and the Company, in equal parts. The External Auditors, their partners, those who sign the reports, those in charge of directing the audit and all members of the audit team must have independence of judgment with respect to SQM and its Related Parties and CORFO; they must not be providing services simultaneously nor have provided during the last 3 years to the Company and its Related Parties, nor to CORFO or its committees, or competitors of the Company, auditing and/or environmental services respectively.

The External Auditors shall issue an annual report, notwithstanding that, at CORFO’s request, a specific review service or a more in-depth analysis that may arise from an audit during the course of the year may be required, in which case, the cost shall be assumed by CORFO. The External Auditors will serve for 3 years. Notwithstanding the foregoing, CORFO or the Directors’ Committee of the Company may terminate in advance, for justified reasons, the term of the contract with the respective auditing firm, appointing a new firm according to the same mechanism stated above for a new three-year term.
