ANNEX 6

RENT CALCULATION MECHANISM

The Company will determine the amount of Rent corresponding to each Rent Period in the manner indicated in Section 7.3 of the Lease Agreement, according to the calculation indicated below:

The Company will pay Rent for each product, as indicated:

Total Rent Payment Period

=Rent Lithium Carbonate Battery Grade

+Rent Lithium Carbonate Technical Grade

+Rent Lithium Hydroxide Battery Grade

+Rent Lithium Hydroxide Technical Grade

+Rent Other Lithium Products

+Rent KCl

+Rent SOP

+Rent ABO

+Rent Magnesium Chloride

+Rent Sodium Chloride

+Rent Other Products

+Fixed Rent

In general, the formula for calculating the Rent for each product is as follows:

Rent = ∑ (Sales Volume x Rate x Sales Price)

Where,

Sales volume	:	Corresponds to the Mt of the product invoiced by the Company.

Rate	:	Corresponds to the progressive and marginal rates applicable on the portion of the Sales Price according to each price range, in accordance with the rate tables shown in Annex No. 5.
Sales Price	:	It will be determined for each product as distinguished in each corresponding situation:

The Sales Price is defined in Dollars. For these purposes, when the sales made and used for the calculation of Rent are expressed in a currency other than Dollars, the currency parity reported by the Central Bank of Chile (or the entity that substitutes or replaces it in such function) will be used for conversion to such currency on the date of issuance of the respective sales document, and in the event that there is no parity value on such date, the parity value of the previous Business Day will be used.

(1)CALCULATION MECHANISM OF LITHIUM PRODUCTS

The following mechanisms will be applicable to the total Mt sold by the Company under the New Quota, Additional Quota and Efficiency Quota. In the case of the Original Quota, which is distributed in equal volumes between 2024 and 2030, the Company will pay exclusively 6.8% on the net sales price imposed per Mt, resulting from the corresponding mechanism detailed below, except as indicated in Section 11.4(c) of the Project Agreement. The Rent calculated at the rate of 6.8% for the Original Quota will be reduced by US$ 272 for each Mt sold as long as the cumulative sale of battery grade Lithium Carbonate, technical grade Lithium Carbonate, technical grade Lithium Hydroxide and battery grade Lithium Hydroxide in each year, measured in Mt does not exceed 60% of the Theoretical Production Capacity (as defined in Annex 9). Once the cumulative sale of battery grade Lithium Carbonate, technical grade Lithium Carbonate, technical grade Lithium Hydroxide and battery grade Lithium Hydroxide in each year, measured in Mt of the same products, exceeds the Minimum Operating Capacity for Guaranteed Payment (Annex 9), this discount will not be applied on the Mt that exceed the annual Minimum Operating Capacity for Guaranteed Payment. All of the above will not be applicable for purposes of calculating

the Rent for Lithium Hydroxide converted from Lithium Carbonate, nor for calculating the Rent for Lithium Products converted from Other Lithium Products in accordance with this Annex 6.

ANNEX 10

EQUIVALENTS

For the purpose of calculating the equivalence between the products sold and the lithium metal allocated as a new quota, additional quota or efficiency quota, the following values and expressions will be considered:

(a)	For each unit of Lithium Carbonate sold, regardless of its quality and/or content, 0.187871578 units of LME will be accounted for.

(b)	For each unit of Lithium Hydroxide anhydride sold, regardless of its quality and/or content, 0.289832681 units of LME will be accounted for.

(c)	For each unit of Lithium Hydroxide monohydrate sold, regardless of its quality and/or content, 0.165405650 units of LME will be accounted for.

(d)	For each unit of lithium sulfate monohydrate sold, regardless of its quality and/or content, 0.108488892 units of LME will be accounted for.

In the event that the Company decides to produce and commercialize Lithium Chloride, the following values and expressions are considered:

(e)	For each unit of Lithium Chloride sold, regardless of its quality and/or content, 0.163725998 units of LME will be accounted for.

In the event that the Company decides to convert lithium sulfate into Lithium Products, the following conversion factors are considered:

(f)	1 Mt of lithium sulfate = 0.513935844 Mt of Lithium Carbonate

(g)	1 Mt of lithium sulfate = 0.583736247 Mt of Lithium Hydroxide

In the event that the Company decides to convert Lithium Carbonate into Lithium Hydroxide, the following conversion factors are considered:

(h)	1 Mt of Lithium Carbonate = 1 Mt of Lithium Hydroxide

Notes:

For Expansion 1 and only once the Lithium Hydroxide and/or Lithium Carbonate production plans for this capacity are defined, the incremental percentages will be applied according to the preferential pricing scheme.

For the Additional Quota and Efficiency Quota, only once the Lithium Hydroxide and/or Lithium Carbonate production plans are defined for the theoretical capacities associated with these quotas, will the incremental percentages be applied according to the preferential pricing scheme.

In the event that the existing plants experience variations in the production volumes of Lithium Hydroxide, the new theoretical volumes will be those that will govern for purposes of the Preferential Price for Specialized Producers.
