CONVERTIBLE NOTES(continued)

(iii)

upon the occurrence of certain significant business events;

(iv)

if, at any time after the calendar quarter ending on March 31, 2022 (and only during such calendar quarter), the last reported price of the Company’s common shares for at least 20 trading days (whether or not consecutive) during the last period of 30 trading days of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day (this has not occurred for the year ended December 31, 2023); or,

(v)

upon a call for redemption by the Company, or upon the Company’s failure to pay the redemption price therefor.

Thereafter, the Convertible Notes will be convertible at any time until the close of business on the business day immediately preceding the maturity date. Upon conversion, the Convertible Notes may be settled, at the Company’s election, in common shares of the Company, cash or a combination thereof. The initial conversion rate for the Convertible Notes was 21.2307 shares perone thousand principal amount of Convertible Notes, equivalent to an initial conversion price of approximately $47.10 per share.

The Convertible Notes mature on January 15, 2027, unless earlier repurchased, redeemed or converted. The Company may not redeem the Convertible Notes prior to December 6, 2024, except upon the occurrence of certain changes to the laws governing Canadian withholding taxes. After December 6, 2024, the Company has the right to redeem the Convertible Notes at its option in certain circumstances including:

(i)

on or after December 6, 2024, if the Company’s share price for at least 20 trading days during any 30 consecutive trading day period ending on, and including, the last trading day of the immediately preceding calendar quarter is over 130% of the conversion price on each applicable trading day, at a redemption price equal to 100% of the principal plus accrued and unpaid interest; and

(ii)

if the Company becomes obligated to pay additional amounts as a result of its obligation to bear the cost of Canadian or non-Canadian withholding tax, if applicable;

Redemption can result in exercisability of the conversion option. Holders of Convertible Notes have the right to require the Company to repurchase their Convertible Notes upon the occurrence of certain events (Note 4).

Pursuant to the indenture governing the terms of the Convertible Notes (the “Indenture”), the holders of Convertible Notes, at their election, were permitted to surrender Convertible Notes for conversion (i) into common shares of the Company during the approximate 30-trading day period prior to the closing of the Separation and (ii) into Lithium Argentina common shares during the period from and after the closing of the Separation until approximately the 35 th trading day after the closing of the Separation. The Conversion Rate (as defined in the Indenture) for the Convertible Notes was initially 21.2307 common shares per $1,000 principal amount of Convertible Notes. Pursuant to the terms and conditions of the Indenture, the Conversion Rate for the Convertible Notes was adjusted on October 17, 2023, to 52.6019 common shares of the Company per $1,000 principal amount of the Convertible Notes based on the trading prices of Lithium Argentina common shares and Lithium Americas (NewCo) common shares over the preceding 10-trading day period. None of the Convertible Notes were surrendered for conversion during the permitted conversion period (Note 4).
