Lithium Americas Corp. ("LAC", "we" or the "Company") may from time to time offer and issue the following securities: (i) common shares of the Company ("Common Shares"); (ii) preferred shares of the Company ("Preferred Shares"); (iii) senior and subordinated debt securities of the Company, including convertible debt securities (collectively, "Debt Securities"); (iv) subscription receipts ("Subscription Receipts") exchangeable for Common Shares and/or other securities of the Company; (v) warrants ("Warrants") exercisable to acquire Common Shares and/or other securities of the Company; and (vi) securities comprised of more than one of Common Shares, Preferred Shares, Debt Securities, Subscription Receipts and/or Warrants offered together as a unit ("Units", and together with the Common Shares, Preferred Shares, Debt Securities, Subscription Receipts and Warrants, the "Securities"), or any combination thereof, having an aggregate offering price of up to US$1,000,000,000 (or the equivalent thereof, at the date of issue, in Canadian dollars or any other currency or currencies, as the case may be), at any time during the 25-month period that this short form base shelf prospectus, including any amendments hereto (the "Prospectus"), remains effective.
