Item 4 Summary of Material Change

The Company and BCP Innovation Pte Ltd. (“BCPI”) signed an investment agreement for funding to advance the construction of the Company’s 50% owned Cauchari-Olaroz lithium project in Jujuy, Argentina (the “Cauchari Project”).

Item 5 Full Description of Material Change

The Bangchak Petroleum Public Company Limited (“Bangchak”), through its wholly-owned subsidiary, BCPI, signed an investment agreement (the “Investment Agreement”) with Lithium Americas for funding to advance the construction of the Cauchari Project. Pursuant to the Investment Agreement, BCPI has agreed to purchase 50,000,000 common shares of the Company at a price of C$0.85 per common share (the “Private Placement”); has agreed to provide US$80 million project debt facility (the “Project Debt Facility”); and will have a right to buy a fixed portion of the lithium carbonate production from the Cauchari-Olaroz project (the “Offtake Entitlement”).

Private Placement

BCPI has agreed to purchase, by way of a private placement, 50,000,000 common shares of the Company at a price of C$0.85 per common share for gross proceeds of C$42.5 million (US$32 million).

Following the close of Private Placement and assuming completion of a private placement contemplated in a concurrent Investment Agreement with GFL International Co., Ltd. (“Ganfeng”), BCPI will own approximately 16.4% of the Company’s issued and outstanding common shares. The common shares issued under the Private Placement will be subject to Lithium Americas shareholder approval and a four month hold period from the closing date. The proceeds of the Private Placement will be used to further advance the Cauchari Project and for general corporate and working capital purposes.

Investor Rights

Provided that BCPI holds not less than 15% of the common shares of the Company, BCPI will also have the following rights, to be included in an Investor Rights Agreement to be signed upon closing:

• the right to add a nominee to Lithium Americas’ board of directors;

• anti-dilution rights allowing it to maintain its equity ownership interest in Lithium Americas at 16.4% until March 31, 2019; and

• a registration right for the sale of its shares.

Project Debt Facility

The parties have also agreed to terms by which BCPI will provide Lithium Americas a Project Debt Facility of up to US$80 million, with security over 30% of Lithium Americas’ interest in the Cauchari Project, which will be used to fund a portion of the construction costs for an initial stage of development at the Cauchari Project (“Stage 1”)

The Project Debt Facility will have a six-year term, and will carry an 8.0% interest rate for the first three years, 8.5% in year four, 9.0% in year five and 9.5% in year six. The facility will become available from the transaction close date and funds will be released to Lithium Americas in instalments to cover Lithium Americas’ capital development contributions on the Cauchari Project. The terms contemplate that for the first three years, there will be no obligation to repay principal. Lithium Americas will be entitled to refinance the loan without penalty at any time after the first year. BCPI’s 15% Offtake Entitlement is conditional on making available all required funding instalments under the Project Debt Facility.

Offtake Entitlement

As part of the Investment Agreement, the parties have agreed to terms of the Offtake Entitlement whereby BCPI will have the right to acquire 15% of Lithium Americas’ share of the Stage 1 production from the Cauchari Project for a period of 20 years following the commencement of commercial production.

Pricing and payment terms of the Offtake Entitlement will be the same as that applicable to SQM for its purchase of lithium carbonate production from the Cauchari Project, which is required to be equivalent to market prices and terms.

In connection with the execution of the Investment Agreement, the Company has also agreed to amend the terms of the investment agreement with Ganfeng, such that, subject to completion of the transactions contemplated with BCPI, Ganfeng’s offtake entitlement will be increased from 70% to 80% of Lithium Americas’ share of Stage I production from the Cauchari Project.

Transaction Details & Timing

The Investment Agreement and the terms of the transactions contemplated thereunder has received requisite Board approvals. Completion of the transaction remains subject to approval of TSX, approval of the shareholders of the Company, completion of definitive agreements for the Offtake Entitlement and Project Debt Facility, closing of the previously announced equity investment by Ganfeng and other customary closing conditions. The Company has also agreed to use its commercially reasonable efforts to procure a voting agreement from Lithium America’s executive officers and directors, Geologic Resource Partners and Ganfeng. Closing is expected to occur on or about March 31, 2017.
