NOTE: THIS NOTICE CONTAINS IMPORTANT INFORMATION THAT IS OF INTEREST TO
THE REGISTERED AND BENEFICIAL OWNERS OF THE SUBJECT NOTES. IF

RECEIVING THIS NOTICE ARE REQUESTED TO EXPEDITE RE-TRANSMITTAL TO

Lithium Americas (Argentina) Corp. (formerly known as Lithium Americas Corp.) ("Corporation") is party to an Indenture dated December 6, 2021 (the "Indenture"), between the Company and Computershare Trust Company N.A., as trustee (the "Trustee"), pursuant to which the Company issued its 1.75% Convertible Senior Notes due 2027 (the "Notes"). Capitalized terms used herein but not otherwise defined shall have the respective meanings given such terms in the Indenture.

On October 3, 2023, the Company implemented by way of a plan of arrangement under the laws of British Columbia (the "Arrangement"), a reorganization resulting in the separation of its North American and Argentine business units into two independent public companies as follows:

The Company became an Argentina focused lithium company owning the Company's interest in its Argentine lithium assets, including the near full-production Caucharí-Olaroz lithium brine project in Jujuy, Argentina; and

The Company created a new North America focused lithium company ("New LAC") owning the Thacker Pass lithium project in Humboldt County, Nevada and the Company's North American investments.

Under the Arrangement, the Company's shareholders retained their proportionate interest in shares of the Company, and received by way of distribution (the "Spin-Off"), newly issued shares of New LAC in proportion to their then-current ownership of the Company. The Spin-Off was also completed on October 3, 2023. As part of the Arrangement, the Company changed its name to Lithium Americas (Argentina) Corp.

The Spin-Off will result in an adjustment to the Conversion Rate for the Notes pursuant to Section 14.04(c) of the Indenture. Pursuant to Section 14.04(c) of the Indenture, the Conversion Rate is required to be adjusted as of the close of business on the last Trading Day of the 10-Trading Day period beginning on, and including, the Ex-Dividend Date for the Spin-Off (October 4, 2023) based on the Last Reported Sale Prices of the Company's Common Shares and New LAC's common shares during such 10-Trading Day period. The New York Stock Exchange informed the Company that the Company's Common Shares began trading regular way on October 4, 2023.

As a result of the Spin-Off and in accordance with Section 14.04(c) of the Indenture summarized above, the Conversion Rate for the Notes has been adjusted to 52.6019 Common Shares of the Company per $1,000 principal amount of Notes, effective at 5:00 p.m., New York City time, on October 17, 2023. Prior to such adjustment, the Conversion Rate for the Notes previously in effect was 21.2307 Common Shares per $1,000 principal amount of Notes.
