FIRST: General Background.

By deed dated January 31, 1986, executed before the Notary Public of Santiago Mr. Sergio Rodríguez Garcés, Amax, Molymet and CORFO 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 CORFO 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. Sergio Rodríguez Garcés, whereby CORFO 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 Mr. Raúl Undurraga Laso, 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

SQM - Corfo Project Agreement

company. Then, by public deed dated November 12, 1993 granted before the Notary Public Juan Ricardo San Martín Urrejola, 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, Mr. Juan Ricardo San Martín Urrejola, the agreement between CORFO, SQMK and SQM was executed, nullifying the agreement of the same name executed in 1986. On the same date and before the same notary, the Lease Agreement was executed between CORFO and Minsal nullifying the 1986 agreement of the same name. The purpose of the Agreement was for Minsal to develop the Project to produce and commercialize all and any 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 Pedro 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 Agreement was amended before the Santiago notary public, Mr. Juan Ricardo San Martín Urrejola, and on December 21, 1995, before the same notary, the Agreement was again amended. Finally, by public deed of the same date and notary, the Parties amended the Agreement. On December 28, 1995, following a capital increase carried out the previous year, CORFO 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 Sal 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 the following into special consideration for purposes of agreeing to the modification and determination of the consolidated text of this Agreement and the Lease Agreement:

2.1 The Agreement and the Lease 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 largest reserves of this mineral in the world, 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 that of batteries and storage devices. Therefore, 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

2 SQM - Corfo Project Agreement

Agreement and the Lease Agreement in order to increase the Company’s lithium production and commercialization quota during the term of the same, 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 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 Lease 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 activity 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: Introduction.

CORFO 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 other 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 Pedro de Atacama, Province of El Loa, Region of Antofagasta, Republic of Chile. In this context and as mentioned above, in 1993 CORFO entered into the Agreement with SQMK and SQM, as well as a lease agreement for certain OMA mining properties with Minsal, which is still in force, whereby

5.2. The Project contemplated and will contemplate the return of the residual brines to an area or areas of the Salar de Atacama within one or more of the current Properties in which the permeability is sufficiently high to allow for entry of the brine in the aquifer in order to make its future extraction possible. Likewise, the Company must protect and safeguard the salt waste and/or discards resulting from the production process with a minimum lithium content of 0.65% on a dry basis, in conditions so that in the future the salt waste or discards may be subject to a production process that technically and economically allows for the recovery of lithium. Notwithstanding the foregoing, in the event that the Company implements a technology that allows the recovery of lithium from the referenced salt waste and/or discards, increasing the efficiency of the production processes of the Salar de Atacama plants, and the Company develops Other Lithium Products derived from such recovered lithium that do not have the degree of processing required for international markets, the Company may dispose of these for purposes of their conversion to Lithium Products and/or Other Lithium Products and their commercialization, which, in any case, must be imputed first to the Efficiency Quota and, once exhausted, to the Additional Quota.

SIXTH: Agreements between the Parties.

6.1. The parties agree to declare or agree as follows:

(a) After the incorporation of and modifications to the Company, SQMK and SQM have made various capital contributions to the Company.

In handling the information referred to in this Clause, CORFO shall be subject to the confidentiality obligations set forth in the Twenty-Seventh Clause (Confidentiality).

ELEVENTH: Special Rules on Lithium.

11.1. The Company must comply with all Chilean laws and regulations governing the extraction, production, marketing and sale of lithium and its by-products. Unless expressly authorized by CCHEN, lithium produced by the Company may not be used or transferred for nuclear fusion purposes. The Company will adopt prudent safeguards to prevent the frustration of this purpose. Additionally, the State of Chile, through CCHEN, will have the first option to purchase the lithium-six

14 SQM - Corfo Project Agreement

eventually produced by the Company at the international price in effect at the time the purchase is made.

11.2. In accordance with the resolution of CCHEN in Agreement Number 1,576, dated October 10, 1995, the Company was authorized to produce and sell up to 180,100 tons of lithium metal equivalent, for a term of 30 years from the first commercial sale of lithium.

11.3. Subject to CCHEN’s prior authorization, the parties agree that the Company shall have the right to exploit, process and sell during the Term of the Agreement, up to 349,553 metric tons of LME, in addition to those referred to in Section 11.2, in successive increments, on the terms indicated below (and reflected in Annex 8):

(a) The New Quota, as of the Commencement Date and notwithstanding the provisions of Section 11.4;

(b) The Additional Quota, in accordance with the terms in Section 11.6; and

(c) The Efficiency Quota, in accordance with the terms set forth in Section 11.7.

(d) The exploitation of the Quotas must comply with the corresponding RCAs.

11.4. In order to be entitled to the New Quota, the Company agrees to construct, develop and operate, in accordance with the Best Engineering and Operation Practices, an expansion of production capacity in addition to its current 66 kMt per year of LCE, capable of producing not less than 50 nominal kMt of battery grade lithium products per year (the “Expansion 1”). Expansion 1 shall be operational no later than the fifth Anniversary. For these purposes, the Company must deliver to CORFO, at the beginning of Expansion 1, the project background, which must include the schedules of the different phases, considering at least the details of the investment amount, land, infrastructure, machinery, third party services, studies, use of direct and indirect labor for each phase incorporating concepts such as physical and financial progress of the investment. Notwithstanding the maximum term already indicated, the Company undertakes to use its best efforts so that Expansion 1 is built and in operation by the fourth Anniversary. If after the fourth Anniversary, Expansion 1 is not constructed, the Company must present, to CORFO’s satisfaction, a progress report and a detailed plan for the completion of the construction and operation of Expansion 1 which must demonstrate that the facility will be in operation before the fifth Anniversary. In any case, if Expansion 1 is not constructed and in operation at the end of the fifth Anniversary, for any circumstance or reason, except as a consequence of Force Majeure, the following effects will occur, notwithstanding the exceptions contemplated in this Section and Section 11.5 (the “Delay Effects”):

(a) The unused remainder of the New Quota and the right to opt for the Additional Quota will terminate;

15 SQM - Corfo Project Agreement

(b) The Company will only be authorized, from that moment on, to exploit an amount not exceeding the Original Quota and/or the Efficiency Quota, as applicable; and

(c) The Company will be obligated to pay the Rent for the Original Quota and for the Efficiency Quota according to the mechanism, rates and form of calculation established for the New Quota.

Notwithstanding everything expressed in this Section, if on the fifth Anniversary Expansion 1 is not in operation, but registers an advancement in the construction of physical works of at least 70%, certified by an independent ITO chosen by CORFO, the Delay Effects shall not be effective. In this event, the Parties shall negotiate in good faith a new economic equilibrium scenario, which allows the economic impact for CORFO of the delay of the start-up of the totality of Expansion 1 to be reflected in the corresponding adjustments to the Rent. The report of the independent ITO referenced above, shall include information that fully addresses the technical, legal and financial situation that the Company needs to resolve for Expansion 1 to be in operation. In no case may the additional term for Expansion 1 to be fully operational, that is, to complete the remaining 30%, exceed the sixth Anniversary. Otherwise, and if such progress has not been verified, the Delay Effects will ipso facto proceed.

11.5. Notwithstanding the provisions of Section 11.4, in order to be entitled to the New Quota, the Company may alternatively execute Expansion 1 divided in 2 parts, each of them with a capacity greater or equal to 25 nominal kMt of battery grade lithium products per year. If the Company utilizes this second alternative, the first of these parts must be implemented and be in operation in accordance with the conditions set forth in Section 11.4; and the second part must be constructed and in operation no later than the seventh Anniversary. In the event that the first  part does not enter into operation in a timely manner, the Delay Effects shall occur ipso facto. If the first part is in operation and the second part is not in operation by the seventh Anniversary, the New Quota will be reduced or limited proportionally to ensure production of the installed capacity and/or existing and operating plants, without limiting the term of the remainder of the Original Quota.

11.6. The Company will have the option to exploit and produce the Additional Quota to the extent that it exercises the option to construct and put into operation an additional production capacity of 100 nominal kMt per year of battery grade lithium products, subject to the fulfillment of the following conditions:

(a) That Expansion 1 is fully implemented and in operation with 50 kMt of annual production of battery grade lithium, through any of the alternatives;

(b) That additional production expansions, in amounts of 25 kMt or more of nominal annual production of battery grade lithium, each one not exceeding 100 kMt in total, are implemented and put into operation, as efficient or advisable in accordance with the Best Engineering and Operation Practices,

16 SQM - Corfo Project Agreement

for which purpose it will be understood that each portion corresponds to a proportional additional quota up to 112,723 Mt of LME.

It is estimated that these additional expansions may begin their first stages of production in approximately 2025, and prior to benefiting from the respective quota increase associated with such expansions, the Company must make the corresponding investments for their entry into operation and exploitation. For purposes of being entitled to the Additional Quota, the Company will inform CORFO in writing about the investments made that allow the production expansions, and CORFO must issue a written opinion within 30 Business Days of receiving such communication regarding the formalization of the Additional Quota.

11.7. The Company will be entitled to the Efficiency Quota to the extent that investments are made that allow future production expansions due to technological changes and innovations that allow efficiency increases in the use of lithium in the extracted brine, up to a maximum of 51,063 Mt of LME. In order to be entitled to the Efficiency Quota, the Company shall inform CORFO in writing about the investments made that allow the production expansions and attach the foundational background, and CORFO shall issue a written opinion within 30 Business Days of receipt of such communication regarding the formalization of the Efficiency Quota.

11.8. In relation to the increases in additional production and exploitation associated with the Additional Quota and/or the Efficiency Quota, the Company will have the option to sell to CORFO or its designee, who in turn, will have the obligation to purchase the referenced installations at the Replacement Value, all of which must be duly audited when the option is exercised by an expert appointed by mutual agreement. This option does not include the Company’s current plants, nor the additional investments made therein that may give rise to the Efficiency Fee. If the Parties do not agree on the name of the expert within 10 working days, the expert shall be appointed by the Arbitral Tribunal established in this Agreement, which shall be constituted for the sole purpose of appointing the expert. The intervention of the Arbitral Tribunal in the appointment of the expert shall not disqualify its members from hearing disputes arising from the determination of the price. If the option is transferred to a third party, the latter shall accept the stipulations set forth in this Clause and in the Twenty-Eighth Clause (Dispute Settlement and Arbitration). In all cases, the assets to which these options and rights relate must be acquired and paid for by the purchaser in cash within 180 days after their price has been determined, and the purchaser shall not have the right to enter into possession of them or exploit them until the price has been fully and definitively paid, if applicable, and the Agreement has been terminated.

TWELFTH: Prior Authorization from CCHEN.

The Company will previously submit to CCHEN for approval, in the form, with the content and under the procedures determined by CCHEN, all contracts or legal acts that it enters into regarding extracted lithium, its concentrates, derivatives or compounds, and will

(a) The Company shall return to CORFO all that personal property and real estate that the latter delivered to the Company by virtue of the Agreement, and, among others, the Assets Subject to Restitution, within a term of 3 months from the aforementioned termination or dissolution;

(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 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 Clause Twenty-Eighth (Dispute Resolution and Arbitration).

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 termination of the Term of the Agreement or within 6 months after the termination 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 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. CORFO’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-Eighth 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.

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 their Related Parties undertake not to extract brine in the aforementioned Protection Ring 2 for a period of 15 years from the termination of the Agreement. In the event that CORFO and/or the third-party holder of the purchase option right exercises such option, they will not be able to extract brine in Protection Ring 2. If the option is transferred to a third party, such third party must accept the stipulations set forth in this Clause and Clause Twenty-Eight (Dispute Resolution and Arbitration).

(f) The transfer of title to the assets covered by the options set forth in Sections 13.1(b), 13.1(d) and 13.1(e) shall be effected within 90 days of the exercise of the options. The transfer of the assets referred to in Sections 13.1(a) and 13.1(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.

EIGHTEENTH: External Auditor.

The Parties agree on the appointment of two external auditors (the “External Auditors”), who will report to CORFO and the Committee regarding the correct, complete and timely compliance with (i) the Company’s environmental obligations (the “Environmental Auditor”) and (ii) the Agreement and Lease Agreement (the “Contract Auditor”) with due regard to CORFO’s own supervisory powers under such contracts. The External Auditors will be proposed by CORFO through a list of three, 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. It shall be understood that those that do not engage in the causes affecting independence of judgment of Articles 243 and 244 of the Securities Market Law have independence of judgment with respect to the Company as an audited entity and its Related Parties. The Contract Auditor must be an accounting auditing firm, responsible for annually reviewing compliance with the Agreement in terms of full and timely payment of the Rent and other financial obligations. Without limiting the foregoing, at CORFO’s request, a specific service of compilation, processing, systematization and certification of the integrity and authenticity of the information and documentation regarding compliance with the Agreement, which could be derived from the regular reviews that CORFO carries out in the performance of its functions, may be required. The list of three candidates to be submitted by CORFO as Contract Auditor shall include companies with experience in accounting auditing and sales for accounting services of at least US$ 1 million in the year prior to their hiring. The list of three candidates to be presented by CORFO as potential Environmental Auditors shall include companies with recognized prestige in this area and with revenues for consulting services in the environmental area of at least US$1 million in the year prior to their hiring. 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 Committee 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 above for a new three-year term. The Company and CORFO must have access to drafts prior to both audits, in order to be able to include their comments and have them annexed to the final report.

32 SQM - Corfo Project Agreement

maintain under strict reserve and confidentiality the information that the Company delivers to it on the occasion of the execution of the Agreements.

27.2. The Parties shall ensure that the External Auditors are subject to the same obligations contained in this Clause.

27.3. The obligations under this Clause shall remain in force for the entire Term of the Agreement and shall survive for the 5 years following its termination.

All difficulties or disputes relating to this Agreement, including, without limitation, those relating to its performance or breach, application, interpretation, validity or invalidity, enforceability, nullity or resolution, termination, determination of damages in connection with its breach and questions relating to the tribunal’s own jurisdiction and venue, shall be resolved by an arbitral tribunal composed of three mixed arbitrators, that is, arbitrators as to procedure and arbitrators ruling in judgment (the “Arbitral Tribunal”), in accordance with the Arbitration Procedural Rules of the Arbitration and Mediation Center of the Santiago Chamber of Commerce A.G. in effect on the date the arbitration proceeding commences. If, together with an arbitration under this Agreement, a dispute arises in relation to the Lease Agreement, both disputes shall be heard by the same arbitral tribunal, and both proceedings shall be joined to end with a single judgment. The Party requesting arbitration shall appoint the first arbitrator together with its request for arbitration to the Arbitration and Mediation Center of the Santiago Chamber of Commerce A.G. and shall communicate to the other party the name of the arbitrator appointed and of the request made to the CAM. The other Party shall appoint the second arbitrator within 15 days of being notified of the request for arbitration and the name of the arbitrator appointed by the other party. The two arbitrators appointed by the Parties shall appoint the third arbitrator within 15 days after the notification of the appointment of the second arbitrator. In the event that (i) the other Party fails to appoint an arbitrator or (ii) the two arbitrators appointed by the Parties fail to reach an agreement with respect to the appointment of a third arbitrator within the time limits set forth above, it shall be the duty of the Santiago Chamber of Commerce A.G. to appoint the second arbitrator and third arbitrator, or only the latter, as the case may be, for which purpose the Parties grant special and irrevocable power of attorney to the Santiago Chamber of Commerce A.G., so that, at the written request of any of the Parties, it may

33 SQM - Corfo Project Agreement

appoint the mixed arbitrators from among the lawyers who are members of the arbitration body of the CAM. Together with the appointment of each arbitrator, the Parties shall have the right to veto, without cause, up to a maximum of three of the arbitrators of the aforementioned arbitration body. If, for any reason, the Santiago Chamber of Commerce A.G. is unable to fulfill its mandate, the appointment of the second and/or third arbitrator, as the case may be, shall be made by any of the judges on duty in civil matters of the commune of Santiago, and the appointment shall be made by a person who has served as an attorney member of the Supreme Court for at least three years, or by a person who, at the time of the appointment, has been a member of the Supreme Court for at least three years, or in a person who at the time of the commitment is a professor of civil law or commercial law of the law schools of the Universidad de Chile or Pontificia Universidad Católica de Chile, based in Santiago, for at least five years.

The arbitration proceedings shall be conducted in the city of Santiago and in a confidential manner, and the appointed arbitrators and the Parties shall be prohibited from communicating to third parties the terms of the arbitration and the background information presented therein or brought to the attention of the Arbitral Tribunal by the opposing party, except insofar as such communication is necessary on the occasion of the appeals or legal proceedings requested or carried out by the Parties or constituting a legal requirement. There will be no recourse against a final judgment of the Arbitral Tribunal, except in the case of a complaint, a cassation appeal on the grounds of ultrapetita or incompetence, and an appeal for clarification, rectification or amendment. An appeal for reconsideration may be lodged against other rulings. The existence of a dispute or controversy regarding the performance or non-performance of the Agreement shall not authorize the Parties to unilaterally suspend the performance of their reciprocal obligations, subject to the Arbitral Tribunal’s decision. In the event of the expiration of the time for the Arbitral Tribunal to exercise its jurisdiction, unless otherwise agreed by the Parties, a new Arbitral Tribunal shall be appointed in the same manner as the first Arbitral Tribunal was appointed, which shall continue the proceedings in the state in which they were at the expiration of the time limit of the first Arbitral Tribunal, all the proceedings before the first Arbitral Tribunal  being valid and effective. In this case, the new Arbitral Tribunal to be appointed shall be composed of persons other than those who were members of the tribunal which failed to perform its duties within the time limit.
