If following the expiration of the sixty-day period (or any mutually agreed upon extension thereof) the parties cannot agree to the validity and amount of such Claim, the Indemnified Party and the appropriate Indemnifying Party shall proceed to establish the merits and amount of such Claim (by confidential arbitration in accordance with Section 11.6) and, within five (5) Business Days following the final determination of the merits and amount, if any, of such Claim, the Indemnifying Party shall pay to the Indemnified Party in immediately available funds an amount equal to such Claim as determined hereunder.

(c)With respect to any Third Party Claim, following the receipt of notice of any Third Party Claim to the Indemnifying Party under Section 10.3(a), the Indemnifying Party shall have the right, by notice to the Indemnified Party given not later than 30 days after receipt of the notice described in Section 10.3(a), to assume the control, defence, compromise or settlement of the Claim, provided that such assumption shall, by its terms, be without cost to the Indemnified Party and provided the Indemnifying Party acknowledges in writing its obligation to indemnify the Indemnified Party in accordance with the terms of this Article.

(d)Upon the assumption of control of any Claim by the Indemnifying Party as set out in Section 10.3(a), the Indemnifying Party shall diligently proceed with the defence, compromise or settlement of the Claim at its sole expense, including, if necessary, employment of counsel reasonably satisfactory to the Indemnified Party and, in connection therewith, the Indemnified Party shall cooperate fully, but at the expense of the Indemnifying Party with respect to any out-of-pocket expenses incurred, to make available to the Indemnifying Party all pertinent information and witnesses under the Indemnified Party's control, make such assignments and take such other steps as in the opinion of counsel for the Indemnifying Party are reasonably necessary to enable the Indemnifying Party to conduct such defence. The Indemnified Party shall also have the right to participate in the negotiation, settlement or defence of any Claim at its own expense.

- 54 -

(e)The final determination of any Claim pursuant to this Section, including all related costs and expenses, shall be binding and conclusive upon the parties as to the validity or invalidity, as the case may be, of such Claim against the Indemnifying Party.

(f)If the Indemnifying Party does not assume control of a Claim as permitted in Section 10.3(a), the obligation of the Indemnifying Party to indemnify the Indemnified Party in respect of such Claim shall terminate if the Indemnified Party settles such claim without the consent of the Indemnifying Party.

(g)Notwithstanding anything to the contrary in this Section 10.3, the indemnity obligations in this Article 10 shall cease to apply to the extent that a court of competent jurisdiction in a final judgment that has become non-appealable shall have determined that any Losses to which an Indemnified Party may be subject were caused solely by the negligence, fraud or wilful misconduct of the Indemnified Party.

(h)Except for any Claims arising from negligence, fraud or wilful misconduct of the Indemnifying Party, the rights to indemnification set forth in this Article 10 shall be the sole and exclusive remedy of the Indemnified Parties (including pursuant to any statutory provision, tort or common law) in respect of:

(i)any non-fulfilment or breach of any covenant or agreement on the part of the Corporation contained in this Agreement; or

(ii)any misrepresentation or any incorrectness in or breach of any representation or warranty of the Corporation contained in this Agreement.

(i)An Indemnified Party shall not be entitled to double recovery for any loss even though such loss may have resulted from the breach of one or more representations, warranties or covenants in this Agreement.

10.4Contribution

If the indemnification provided for in this Article 10 is held by a court of competent jurisdiction to be unavailable to a Indemnified Party with respect to any Losses referred to herein, the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with matters that resulted in such Loss, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement, omission or fault.

- 55 -

10.5Survival

Each party hereto acknowledges that the representations, warranties and agreements made by it herein are made with the intention that they may be relied upon by the other party. The parties further agree that the representations, warranties, covenants and agreements shall survive the purchase and sale of the Subscription Receipts and shall continue in full force and effect for a period ending on the date that is twelve (12) months following the Escrow Release Date, notwithstanding any subsequent disposition by the Investor of the Subscription Receipts or any termination of this Agreement; provided, however, that the representations and warranties of the Corporation set forth in Sections 3.1(a) (Due Authorization), 3.1(b) (Organization and Existence), 3.1(c) (Non-Contravention), 3.1(d) (No Violation) and 3.1(f) (Subsidiaries) of this Agreement and the representations of the Investor set forth in Section 3.2(a) (Due Authorization) of this Agreement shall survive indefinitely (the survival date of each representation, warranty, covenant and agreement herein as set forth above is referred to as the "Survival Date"). This Agreement shall be binding upon and shall enure to the benefit of the parties hereto, their respective successors, assigns and legal representatives. Notwithstanding the foregoing, the provisions contained in this Agreement related to indemnification or contribution obligations shall survive and continue in full force and effect, indefinitely, provided that, no Claim for indemnity pursuant to this Article 10 may be made after the Survival Date for the applicable representation, warranty, covenant or agreement unless notice of the Claim was provided to the Indemnifying Party on or prior to the Survival Date.

10.6Duty to Mitigate

Nothing in this Agreement shall in any way restrict or limit the general obligation at law of a party hereto to mitigate any loss which it may suffer or incur by reason of a breach of any representation, warranty or covenant of that other party under this Agreement. If any Loss can be reduced by any recovery, settlement, or payment by or against any other Person, a party hereto shall take all appropriate steps to enforce such recovery, settlement or payment. If the Indemnified Party fails to make all commercially reasonably efforts to mitigate any Loss, then the Indemnifying Party shall not be required to indemnify any Indemnifying Party for the Loss that could have been avoided if the Indemnified Party had made such efforts.

10.7Trustee

Each party hereto hereby acknowledges and agrees that, with respect to this Article 10, the Investor is contracting on its own behalf and as agent for the other Investor Indemnified Parties referred to in this Article 10 and the Corporation is acting on its own behalf and as agent for the other Corporation Indemnified Parties referred to in this Article 10. In this regard, the Investor shall act as trustee for such Investor Indemnified Parties of the covenants of the Corporation under this Article 10 with respect to such Investor Indemnified Parties and accepts these trusts and shall hold and enforce those covenants on behalf of such Investor Indemnified Parties, and the Corporation shall act as trustee for such Corporation Indemnified Parties of the covenants of the Investor under this Article 10 with respect to such Corporation Indemnified Parties and accepts these trusts and shall hold and enforce those covenants on behalf of such Corporation Indemnified Parties.

(c)upon the issuance thereof, and until such time as the same is no longer required under the applicable requirements of the U.S. Securities Act or applicable State securities laws, the certificates or ownership statements (including any confirmation under the Direct Registration System (DRS) maintained by the Corporation, its transfer agent or the warrant agent, if and as applicable) representing any of the Subscription Receipts, Units, Purchased Shares, Warrants, Warrant Shares will bear a legend in substantially the following form:

"THE SECURITIES REPRESENTED HEREBY [for Subscription Receipts/Warrants add: AND THE SECURITIES ISSUABLE PURSUANT HERETO / UPON EXERCISE HEREOF] HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S. SECURITIES ACT") OR UNDER THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF LITHIUM AMERICAS CORP. AND ITS SUCCESSORS (THE "CORPORATION") THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ABSENT SUCH REGISTRATION ONLY (A) TO THE CORPORATION; (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN COMPLIANCE WITH LOCAL LAWS AND REGULATIONS; (C) IN ACCORDANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS; OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, AND, IN THE CASE OF CLAUSE (C) OR (D), THE HOLDER HAS PRIOR TO SUCH TRANSFER FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION TO SUCH EFFECT. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE GOOD DELIVERY IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA."

and provided that if any of the Subscription Receipts, Units, Purchased Shares, Warrants, Warrant Shares are being sold by the Investor in an off-shore transaction and in compliance with the requirements of Rule 904 of Regulation S, the legend set forth above may be removed by providing such evidence as the Corporation or its transfer agent may from time to time reasonably prescribe (which may include an opinion of counsel reasonably satisfactory to the Corporation and its transfer agent), to the effect that the sale of the Subscription Receipts, Units, Purchased Shares, Warrants, Warrant Shares is being made in compliance with Rule 904 of Regulation S;

and provided further, that if any of the Subscription Receipts, Units, Purchased Shares, Warrants, Warrant Shares are being sold pursuant to Rule 144 of the U.S. Securities Act and in compliance with any applicable State securities laws, the legend may be removed by delivery to the Corporation's transfer agent of an opinion reasonably satisfactory to the Corporation and its transfer agent to the effect that the legend is no longer required under applicable requirements of the U.S. Securities Act and State securities laws;

(d)the Corporation may make a notation on its records or instruct the registrar and transfer agent of the Corporation in order to implement the restrictions on transfer set forth and described herein and the subscription;

(e)the Investor understands and agrees that the financial statements of the Corporation have been prepared in accordance with International Financial Reporting Standards, which differ in some respects from United States generally accepted accounting principles, and thus may not be comparable to financial statements of United States companies;

(f)the Investor understands that the Subscription Receipts, Units, Purchased Shares, Warrants and Warrant Shares are "restricted securities" under applicable federal securities laws and that the U.S. Securities Act and the rules of the Securities and Exchange Commission (the "SEC") provide in substance that the Investor may dispose of the Subscription Receipts, Units, Purchased Shares, Warrants and Warrant Shares only pursuant to an effective registration statement under the U.S. Securities Act or an exemption therefrom, and, other than as set out herein or in the Investor Rights Agreement, the Investor understands that the Corporation has no obligation to register the offer or sale of any of the Subscription Receipts, Units, Warrants, Warrant Shares or the Purchased Shares or to take action so as to permit sales pursuant to the U.S. Securities Act (including Rule 144 thereunder). Accordingly, the Investor understands that absent registration, under the rules of the SEC, the Investor may be required to hold the Purchased Shares, Units, Warrants, Warrant Shares indefinitely or to transfer the Purchased Shares, Units, Warrants, Warrant Shares in the United States or to U.S. Persons in "private placements" which are exempt from registration under the U.S. Securities Act, in which event the transferee may acquire "restricted securities" subject to the same limitations as in the hands of the Investor. As a consequence, the Investor understands that it must bear the economic risks of the investment in the Subscription Receipts, Purchased Shares, Units, Warrants, and Warrant Shares for an indefinite period of time.

UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE [●], 2023.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE ("TSX"); HOWEVER, THE SAID SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE REPRESENTING SUCH SECURITIES IS NOT "GOOD DELIVERY" IN SETTLEMENT OF TRANSACTIONS ON THE TSX.

The following legend will be placed on the certificates representing the Warrant Shares upon the issuance thereof, until such time as the same is no longer required under the applicable requirements of the U.S. Securities Act or applicable U.S. Securities Laws and regulations:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S. SECURITIES ACT") OR UNDER THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF LITHIUM AMERICAS CORP. AND ITS SUCCESSORS (THE "CORPORATION") THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ABSENT SUCH REGISTRATION ONLY (A) TO THE CORPORATION; (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN COMPLIANCE WITH LOCAL LAWS AND REGULATIONS; (C) IN ACCORDANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS; OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, AND, IN THE CASE OF CLAUSES (C) OR (D), THE HOLDER HAS PRIOR TO SUCH TRANSFER FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION TO SUCH EFFECT. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE GOOD DELIVERY IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.

2.6The Warrants represented hereby and the securities issuable upon the exercise of the Warrants represented hereby have not been and will not be registered under the U.S. Securities Act or the Securities Laws of any state. The Warrants represented hereby may not be exercised by or for the account of a U.S. Person or a Person in the United States without registration under the U.S. Securities Act and all applicable state Securities Laws or unless an exemption from such registration is available and, upon request by the Corporation, the holder has provided the Corporation with a written opinion of United States legal counsel or other evidence reasonably satisfactory to the Corporation to such effect. Notwithstanding the foregoing, a holder who checks box 3 of the Warrant Exercise Form and represents, warrants and certifies to the Corporation that (a) it purchased the Warrants from the Corporation pursuant to the Master Purchase Agreement, (b) it is exercising the Warrants for its own account, (c) it is an "accredited investor" (as defined in Rule 501(a) of Regulation D under the U.S. Securities Act) on the date of exercise, and (d) the representations and warranties of the holder set forth in the Master Purchase Agreement (other than representations regarding the holder's ownership of the Corporation's equity securities at the time of entry into the Master Purchase Agreement) remain true and correct on the date of exercise, shall not be required to deliver a written opinion of United States counsel upon exercise of the Warrant. The Warrant Shares shall bear the legend set forth in Warrant Exercise Form. As used herein, the terms "United States" and "U.S. Person" have the meaning ascribed thereto in Regulation S under the U.S. Securities Act.

8

2.7Restrictions on Exercise Amount. In the event the Corporation is prohibited from issuing Warrant Shares as a result of any restrictions or prohibitions under applicable law or the rules or regulations of any stock exchange, interdealer quotation system or other self-regulatory organization, the Corporation shall as soon as possible take such commercially reasonable action to authorize the issuance of the full number of Warrant Shares issuable upon exercise of this Warrant Certificate.

2.8Investment Purposes. The Holder confirms that Holder is subscribing for the Warrants as principal for its own account and not as agent for the benefit of any other Person (within the meaning of Securities Laws) for investment purposes only and has no current intention to sell or otherwise dispose of the Warrants.

3.Transfer, Division and Combination.

3.1Transfer. The Warrants shall not be transferrable by the Holder, except with the prior written consent of the Corporation. Notwithstanding the foregoing, the Holder may assign and transfer all of its rights, benefits, duties and obligations under this Certificate in their entirety, without the consent of the Corporation, to an Affiliate of the Holder; provided that no such assignment shall relieve the Holder of any of its obligations hereunder. The Corporation may not transfer all or any interest in this Warrant Certificate, except as explicitly set forth in Section 4 and 5 of this Warrant Certificate.

Any Transfer of the Warrants and all rights hereunder, in accordance with the foregoing provisions, shall be registered on the books of the Corporation to be maintained for such purpose, upon surrender of this Warrant Certificate at the principal office of the Corporation or the office or agency designated by the Corporation pursuant to Section 14.2, together with a written assignment of the Warrants substantially in the form of Exhibit B hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such Transfer. Upon such surrender and, if required, such payment, the Corporation shall execute and deliver a new Warrant Certificate in the name of the assignee or assignees and in the denomination specified in such instrument of assignment and shall issue to the assignor a new Warrant Certificate evidencing the number of Warrants not so assigned, and this Warrant Certificate shall promptly be cancelled. Following a Transfer that complies with the requirements of this Section 3.1, the Warrants may be exercised by a new Holder for the purchase of Warrant Shares regardless of whether the Corporation issued or registered a new Warrant Certificate on the books of the Corporation.

9

The Warrants are, and Warrant Shares will be, "restricted securities" within the meaning of Rule 144(a)(3) under the U.S. Securities Act, and, if in the future the Holder decides to offer, resell, pledge or otherwise transfer such securities, it will do so only (a) to the Corporation; (b) outside the United States in compliance with Rule 904 of Regulation S under the U.S. Securities Act, and in compliance with applicable local laws and regulations; (c) in compliance with (i) Rule 144A under the U.S. Securities Act, if available, to a Person the seller reasonably believes is a "qualified institutional buyer" (as defined in Rule 144A under the U.S. Securities Act) that is purchasing for its own account or for the account of one or more "qualified institutional buyers" and to whom notice is given that the offer, sale, pledge or transfer is being made in reliance upon Rule 144A under the U.S. Securities Act, or (ii) Rule 144 under the U.S. Securities Act, if available, and, in each case, in compliance with any applicable state Securities Laws of the United States; or (d) in another transaction that does not require registration under the U.S. Securities Act or any applicable state Securities Laws of the United States, after (A) in the case of proposed transfers pursuant to (b) above, providing to Computershare Investor Services Inc., as transfer agent for the Corporation, (i) a declaration in the form that Computershare Investor Services Inc., as transfer agent for the Corporation, may reasonably prescribe from time to time, and (ii) if required by Computershare Investor Services Inc., as transfer agent for the Corporation, an opinion of counsel, of recognized standing reasonably satisfactory to the Corporation, or other evidence satisfactory to the Corporation, that the proposed transfer may be effected without registration under the U.S. Securities Act, and (B) in the case of proposed transfers pursuant to (c)(ii) or (d) above, providing to Computershare Investor Services Inc., as transfer agent for the Corporation, and to the Corporation, an opinion of counsel of recognized standing reasonably satisfactory to the Corporation, to the effect that the proposed transfer may be effected without registration under the U.S. Securities Act.

4.Warrant Adjustments.

4.1Adjustments. The number of Warrant Shares for which the Warrants are exercisable, and the price at which such shares may be purchased upon exercise of the Warrants, shall be subject to adjustment from time to time as set forth in this Section 4, excluding any adjustments to be made in connection with the Separation Transaction, which will be governed by the provisions of Section 5. The Corporation shall give the Holder notice of any event described below which requires an adjustment pursuant to this Section 4 in accordance with Section 6.1 and 6.2.

4.2Share Dividends, Subdivisions and Combinations. If at any time while the Warrants are outstanding the Corporation shall:

10

(a)declare a dividend in Common Shares or Convertible Securities or make a distribution of Common Shares or Convertible Securities on all or substantially all of its outstanding Common Shares,

(b)subdivide its outstanding Common Shares into a larger number of Common Shares, or

(c)combine its outstanding Common Shares into a smaller number of Common Shares,

then, on the record date for such event or, if no record date is fixed, the effective date of such event, in each case:

(1)the Current Warrant Price shall be adjusted so that it will equal the rate determined by multiplying the Current Warrant Price in effect immediately prior to such date by a fraction, of which the numerator shall be the total number of Common Shares Deemed Outstanding on such date before giving effect to such event, and of which the denominator shall be the total number of Common Shares Deemed Outstanding on such date after giving effect to such event, and

(2)the number of Warrant Shares purchasable upon the subsequent exercise of the Warrants shall be simultaneously adjusted or readjusted, as the case may be, by multiplying the number of Warrant Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment or readjustment by a fraction which shall be the reciprocal of the fraction used in the adjustment or readjustment of the Current Warrant Price.

Any adjustment made pursuant to clause (a) of this paragraph shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clauses (b) or (c) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.

4.3Rights Offering. If at any time while the Warrants are outstanding the Corporation shall fix a record date for the issuance of rights, options or warrants to all or substantially all the holders of Common Shares entitling them, for a period expiring not more than 45 days after the record date, to subscribe for or purchase Common Shares or Convertible Securities at a price per Common Share (or having a conversion price per Common Share) less than 95% of the Current Market Price as at the record date (the issuance of any such rights, options or warrants being a "Rights Offering"), then the Current Warrant Price shall be adjusted effective immediately after the record date so that it shall equal the price determined by multiplying the Current Warrant Price in effect on the record date of such Rights Offering by a fraction:

(a)the numerator of which shall be the number of Common Shares Deemed Outstanding on the record date plus a number of Common Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Common Shares offered for subscription or purchase (or the aggregate conversion price of the Convertible Securities so offered) by the Current Market Price; and

11

(b)the denominator shall be the number of Common Shares Deemed Outstanding on the record date plus the total number of additional Common Shares offered by subscription or purchase (or into which the Convertible Securities so offered are convertible);

to the extent that any such rights, options or warrants are not so issued or are not exercised prior to the expiration thereof, the Current Warrant Price shall be readjusted to the Current Warrant Price which would then be in effect if the record date had not been fixed or the Current Warrant Price which would then be in effect based upon the number of Common Shares (or Convertible Securities) actually issued upon the exercise of such rights, options and warrants, as the case may be, but subject to any other adjustment required hereunder by reason of any event arising after the record date.

4.4Special Distribution. If at any time while the Warrants are outstanding the Corporation shall issue or distribute to all or substantially all the holders of Common Shares:

(a)shares of any class other than Common Shares (excluding for the avoidance of doubt any SpinCo Shares or other securities of SpinCo issued pursuant to the Separation Transaction), or

(b)rights, options or warrants (other than (i) pursuant to a employee stock option plan or employee share purchase plan or other employment incentive, (ii) rights, options or warrants exercisable not more than 45 days from the date of issue to purchase Common Shares at a price per Common Share equal to or greater than the Current Warrant Price or to purchase Convertible Securities having a conversion price per Common Share equal to or greater than the Current Warrant Price or (iii) as provided for in Section 4.3), or

(c)evidences of indebtedness, or

(d)any other assets (other than a cash dividend payable out of the earnings or earned surplus legally available for the payment of dividends under the laws of the jurisdiction of incorporation of the Corporation)

and, in any of those cases, the issuance or distribution does not constitute a distribution to which Sections 4.2 or 4.3 applies (any of such events being herein called a "Special Distribution"), then the Current Warrant Price shall be adjusted effective immediately after the record date at which the holders of Common Shares are determined for purposes of the Special Distribution to a price which is the product of:

(i)the Current Warrant Price in effect on such record date; and

(ii)a fraction:

(1)the numerator shall be the number of Common Shares Deemed Outstanding on the record date multiplied by the Current Market Price on the record date, less the fair market value (as determined by the directors acting in good faith with a view to the interests of all of the security holders of the Corporation, including the Holder) of the shares, evidences of indebtedness, assets or property, or rights, options or warrants so distributed; and

12

(2)the denominator shall be the number of Common Shares Deemed Outstanding on the record date multiplied by such Current Market Price.

to the extent that the Special Distribution is not so made or to the extent that any rights, options or warrants so distributed are not exercised, the Current Warrant Price shall be readjusted to the Current Warrant Price which would then be in effect based upon such shares, rights, options, warrants, evidences of indebtedness or assets actually distributed or based upon the number of Common Shares or Convertible Securities actually delivered upon the exercise of such rights, options or warrants, as the case may be, but subject to any other adjustment required hereunder by reason of any event arising after the record date.

4.5Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets.

(a)If there shall occur a reclassification or redesignation of Common Shares at any time or a change of the Common Shares into other shares or other securities or any other capital reorganization (other than a share dividend, subdivision or combination referred to in Section 4.1), or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other corporation or other entity (other than a consolidation, amalgamation, arrangement or merger which does not result in any reclassification or redesignation of the Common Shares or a change of the Common Shares into other securities), or a transfer of all or substantially all of the undertaking or assets of the Corporation to another corporation or other entity (any of such events being herein called a "Capital Reorganization"), and, pursuant to the terms of such Capital Reorganization, common shares of the successor or acquiring corporation, or any cash, shares or other securities or property of any nature whatsoever (including warrants or other subscription or purchase rights) in addition to or in lieu of common shares of the successor or acquiring corporation (any such consideration other than Common Shares, the "Other Property"), are to be received by or distributed to the holders of Common Shares, then the Holder of the Warrants shall have the right thereafter to receive, and still accept upon the exercise of the Warrant in lieu of the Common Shares to which such Holder was therefore entitled to receive, the number of Common Shares and the Other Property receivable upon or as a result of such Capital Reorganization by a holder of the number of Common Shares into which the Warrant is exercisable immediately prior to such event.

(b)Subject to the prior written approval of the principal stock exchange or over-the-counter market on which the Common Shares are then listed or quoted for trading, appropriate adjustments shall be made as a result of any such Capital Reorganization in the application of the provisions set forth in this Section 4.4 with respect to the rights and interests thereafter of the Holder to the end that the provisions set forth in this Section 4.4 shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares, other securities or Other Property thereafter deliverable upon the exercise of any Warrant. Any such adjustments shall be made by and set forth in terms and conditions supplemental hereto approved by the board of directors of the Corporation, acting reasonably and in good faith. The foregoing provisions of this Section 4 shall similarly apply to successive Capital Reorganization transactions.

13

4.6Other Provisions Applicable to Adjustments. The following provisions shall be applicable to the making of adjustments of the number of Common Shares into which the Warrants are exercisable and the Current Warrant Price provided for in Section 4:

(a)The adjustments required by Section 4 shall be made whenever and as often as any specified event requiring an adjustment shall occur, subject to the following subsections of this Section 4, and for the purpose of any adjustment, any specified event shall be deemed to have occurred at the close of business on the date of its occurrence.

(b)No adjustment in the Current Warrant Price is required to be made unless such adjustment would result in a change of at least 1% in the prevailing Current Warrant Price and no adjustment in the Current Warrant Price is required to be made unless such adjustment would result in a change of at least one one-hundredth of a Warrant Share upon exercise of the Warrants; provided, however, that any adjustments which, except for the provisions of this subsection, would otherwise have been required to be made, will be carried forward and taken into account in any subsequent adjustments, and in any case, prior to exercise.

(c)In computing adjustments under this Section 4, fractional interests of less than 0.5 of one Common Share shall be rounded down, and fractional interests of 0.5 or more of one Common Share shall be rounded up, in each case to the nearest whole share.

(d)If the Corporation undertakes a transaction contemplated under this Section 4 and as a result takes a record of the holders of its Common Shares for the purpose of entitling them to receive a dividend or distribution or subscription or purchase rights or other benefits contemplated under this Section 4 and shall, thereafter and before the distribution to shareholders thereof, legally abandon its plan to pay or deliver such dividend, distribution, subscription or purchase rights or other benefits contemplated under this Section 4, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

(e)If at any time a question or dispute arises with respect to adjustments provided for in Section 4, such question or dispute will be conclusively determined by the independent auditor of the Corporation or, if they are unable or unwilling to act, by such other firm of independent chartered professional accountants that is a participant of the Canadian Public Accountability Board, as may be selected by action of the Holder and any such determination, subject to regulatory approval and absent manifest error, will be binding upon the Corporation and the Holder. The Corporation will provide such independent auditor or chartered professional accountant with access to all necessary records of the Corporation.

14

(f)In the absence of a resolution of the directors of the Corporation fixing a record date for any event which would require any adjustment to these Warrants, the Corporation will be deemed to have fixed as the record date therefor the date on which the event is effected.

(g)In any case that an adjustment pursuant to Section 4 shall become effective immediately after a record date for or an effective date of an event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the Holder of these Warrants, if exercised after such record date or effective date and before the occurrence and consummation of such event, the additional Warrant Shares or other securities or property issuable upon such exercise by reason of the adjustment required by such event, provided, however, that the Corporation will deliver to the Holder an appropriate instrument evidencing the Holder's right to receive such additional Warrant Shares or other securities or property upon the occurrence and consummation of such event and the right to receive any dividend or other distribution in respect of such additional Warrant Shares or other securities or property declared in favour of the holders of record of Common Shares or of such other securities or property on or after the Expiration Date or such later date as the Holder would, but for the provisions of this subsection, have become the holder of record of such additional Warrant Shares or of such other securities or property.

4.7No Adjustments. No adjustment in the Current Warrant Price or number of Warrants issuable hereunder shall be made in respect of the Separation Transaction (provided a warrant certificate is issued by SpinCo for the purchase of SpinCo Shares as contemplated in Section 5).

4.8Other Action Affecting Common Shares. If and whenever at any time after the date hereof and prior to the Expiration Date, the Corporation takes any action affecting its Common Shares to which the foregoing provisions of this Section 4 are not strictly applicable, or if strictly applicable would not fairly adjust the rights of the Holder against dilution in accordance with the intent and purposes thereof, or would otherwise materially affect the rights of the Holder hereunder, then the Corporation shall execute and deliver to the Holder an amendment hereto providing for an adjustment in the application of such provisions so as to adjust such rights as aforesaid in such a manner as the board of directors of the Corporation may determine to be equitable in the circumstances, acting reasonably and in good faith, but subject in all cases to any necessary regulatory approval.

4.9Common Share Transfer Taxes. The issue of share certificates upon exercise of the Warrants shall be made without charge to the Holder for any stamp or issuance tax in respect of such issue. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any Transfer involved in the issue and delivery of shares in any name other than that of the Holder, and the Corporation shall not be required to issue or deliver any such share certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid.

15

4.10Deemed Termination. This Warrant Certificate will terminate automatically and with immediate effect upon the date (the "Mandatory Cancellation Date") either:

(a)the Holder or any other Person subscribes for and purchases Common Shares pursuant to the terms of the Tranche 2 Subscription Agreement;

(b)the Tranche 2 Subscription Agreement is terminated pursuant to its terms; or

(c)the Share Pricing Resolution is approved at the GM Transaction Shareholder Meeting.

5.SpinCo Warrants.

5.1Warrants to be issued by SpinCo. If the Warrants hereunder have not been exercised prior to the Separation Transaction, the parties agree that in connection with the Separation Transaction, the Holder of this Warrant Certificate shall exercise this Warrant Certificate to acquire one (1) Common Share.

The parties further acknowledge and agree that immediately after the Separation Transaction, the Corporation shall cause SpinCo to provide the Holder with new warrant certificate on substantially the terms of this Warrant Certificate (the "SpinCo Warrant Certificate") with such equitable adjustments as are necessary to give effect to the Separation Transaction, including as further provided in Section 5.2.

5.2Terms of SpinCo Warrant Certificate. The SpinCo Warrant Certificate shall be on substantially the terms of this Warrant Certificate with certain necessary modifications, including the following:

(a)all references to the "Corporation" and to the "Issuer" in this Warrant Certificate shall refer to SpinCo;

(b)all references to the "Tranche 2 Subscription Agreement" in this Warrant Certificate shall refer to the SpinCo Subscription Agreement;

(c)the SpinCo Warrant Certificate shall entitle the holder to acquire SpinCo Shares, with (i) each Warrant being exercisable to acquire one (1) SpinCo Share; (ii) the Current Warrant Price for the exercise of each Warrant being adjusted to a price equal to the Current Warrant Price immediately prior to such adjustment multiplied by the Relative SpinCo Value Ratio; and (iii) the number of Warrants represented by this Certificate being adjusted to equal the number of Warrants outstanding immediately prior to the Separation Transaction divided by the Relative SpinCo Value Ratio (in each case of clause (ii) and (iii) subject to adjustment in the event that Common Shares and SpinCo Shares and are not issued on one-for-one basis in connection with the Separation Transaction);

16

(d)the definition of Warrant Shares shall be replaced with the following: ""Warrant Shares" means the SpinCo Shares to be purchased upon the due and valid exercise of the Warrants represented by this Warrant Certificate, subject to adjustment as provided herein"; and

(e)all references to the Separation Transaction or to the rights and obligations of the Corporation or the Holder in respect of the Separation Transaction shall be removed.

6.Notices to Warrant Holders.

6.1The Corporation will from time to time, immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Section 4, forthwith give notice to the Holder specifying the event in reasonable detail requiring such adjustment or readjustment and the results thereof, including the resulting Current Warrant Price.

6.2No Rights as Shareholder. This Warrant Certificate does not entitle the Holder to any voting or other rights as a shareholder of the Corporation prior to due exercise and payment of the Warrant Price in accordance with the terms hereof.

7.No Impairment. The Corporation shall not by any action, including, without limitation, amending its constating documents or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant Certificate, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder against impairment. Without limiting the generality of the foregoing, the Corporation will (a) take all such commercially reasonable action as may be necessary or appropriate in order that the Corporation may validly and legally issue fully paid and non-assessable Common Shares upon the exercise of this Warrant Certificate, and (b) use its commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Corporation to perform its obligations under this Warrant Certificate (other than the filing of a prospectus or registration statement). Upon the request of the Holder, the Corporation will at any time during the period the Warrants are outstanding acknowledge in writing, in form satisfactory to the Holder, the continuing validity of the Warrants and the obligations of the Corporation hereunder.

8.Reservation and Authorization of Common Shares; Registration With Approval of Any Governmental Entity. From and after the Closing Date, the Corporation shall at all times reserve and keep available for issue upon the exercise of Warrants such number of its authorized but unissued Common Shares as will be sufficient to permit the exercise in full of all outstanding Warrants. All Common Shares which shall be so issuable, when issued upon exercise of any Warrant and payment therefor in accordance with the terms of such Warrant, shall be duly and validly issued and fully paid and non-assessable. Before taking any action which would cause an adjustment reducing the Current Warrant Price below the then par value, if any, of the Common Shares issuable upon exercise of the Warrants, the Corporation shall take any corporate action which may be necessary in order that the Corporation may validly and legally issue fully paid and non-assessable shares of such Common Shares at such adjusted Current Warrant Price. Before taking any action which would result in an adjustment in the number of Common Shares for which this Warrant Certificate is exercisable or in the Current Warrant Price, the Corporation shall use its commercially reasonable efforts to obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof (other than filing a prospectus or registration statement).

17

9.If Share Transfer Books Closed. The Corporation shall not be required to deliver certificates for Warrant Shares while the share transfer books of the Corporation are properly closed, including prior to any meeting of shareholders or for the payment of dividends or for any other purpose and in the event of the surrender of any Warrant in accordance with the provisions hereof, and the making of any subscription and payment for the Warrant Shares called for thereby during any such period delivery of certificates for Warrant Shares may be postponed for a period of three (3) Business Days after the date of the re-opening of said share transfer books.

10.Supplying Information. Upon any default by the Corporation of its obligations hereunder, the Corporation shall cooperate with the Holder in supplying such information as may be reasonably necessary for the Holder to complete and file any information reporting forms presently or hereafter required by applicable Securities Laws as a condition to the availability of an exemption from such Securities Laws for the sale of any Warrant or Warrant Shares issued upon exercise of a Warrant.

11.Loss or Mutilation. Upon receipt by the Corporation from the Holder of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of this Warrant Certificate and indemnity or security reasonably satisfactory to it and reimbursement to the Corporation of all reasonable expenses incidental thereto and in case of mutilation upon surrender and cancellation hereof, the Corporation will execute and deliver in lieu hereof a new Warrant Certificate of like tenor to the Holder; provided, however, that in the case of mutilation, no indemnity shall be required if this Warrant Certificate in identifiable form is surrendered to the Corporation for cancellation.

12.Office of the Corporation. As long the Warrants remain outstanding, the Corporation shall maintain an office or agency (which may be the principal executive offices of the Corporation) where the Warrants may be presented for exercise, registration of Transfer, division or combination as provided in this Warrant Certificate.

13.Limitation of Liability. No provision hereof, in the absence of affirmative action by the Holder to purchase Common Shares, and no enumeration herein of the rights or privileges of the Holder hereof, shall give rise to any liability of the Holder for the purchase price of any Common Shares, whether such liability is asserted by the Corporation or by creditors of the Corporation.

18

14.Miscellaneous.

14.1Non-waiver. No course of dealing or any delay or failure to exercise any right hereunder on the part of the Holder shall operate as a waiver of such right.

Such notice shall specify whether the Claim arises as a result of a claim by a third party Person (a "Third Party") against the Indemnified Party (a "Third Party Claim") or whether the Claim does not so arise (a "Direct Claim"), and shall also include a description of the Loss in reasonable detail including the sections of this Agreement which form the basis for such Loss, copies of all material written evidence of such Loss in the possession of the Indemnified Party and the actual or estimated amount of the damages that have been or will sustained by any Indemnified Party, including reasonable supporting documentation therefor; provided that the failure to so notify the Indemnifying Party shall not relieve such Indemnifying Party of its obligations hereunder unless and to the extent the Indemnifying Party is actually and materially prejudiced by such failure to so notify.

(g)Notwithstanding anything to the contrary in this Section 8.3, the indemnity obligations in this Article 8 shall cease to apply to the extent that a court of competent jurisdiction in a final judgment that has become non-appealable shall have determined that any Losses to which an Indemnified Party may be subject were caused solely by the negligence, fraud or wilful misconduct of the Indemnified Party.

(i)any non-fulfilment or breach of any covenant or agreement on the part of the Corporation contained in this Agreement; or

(ii)any misrepresentation or any incorrectness in or breach of any representation or warranty of the Corporation contained in this Agreement.

- 40 -

8.4Contribution

If the indemnification provided for in this Article 8 is held by a court of competent jurisdiction to be unavailable to a Indemnified Party with respect to any Losses referred to herein, the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with matters that resulted in such Loss, as well as any other relevant equitable considerations.

(b)if the Investor decides to offer, sell or otherwise transfer any of the Purchased Shares, it will not offer, sell or otherwise transfer any of such securities, directly or indirectly, unless:

(i)the sale is to the Corporation;

(iii)the sale is made pursuant to the requirements of Rule 904 promulgated under the U.S. Securities Act;

(iv)the sale is made pursuant to the exemption from the registration requirements under the U.S. Securities Act provided by Rule 144 thereunder if available and in accordance with any applicable State securities laws; or

(c)upon the issuance thereof, and until such time as the same is no longer required under the applicable requirements of the U.S. Securities Act or applicable State securities laws, the certificates representing any of the Purchased Shares will bear a legend in substantially the following form:

"THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S. SECURITIES ACT") OR UNDER THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF LITHIUM AMERICAS CORP. AND ITS SUCCESSORS (THE "CORPORATION") THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ABSENT SUCH REGISTRATION ONLY (A) TO THE CORPORATION; (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN COMPLIANCE WITH LOCAL LAWS AND REGULATIONS; (C) IN ACCORDANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS; OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, AND, IN THE CASE OF CLAUSES (C) OR (D), THE HOLDER HAS PRIOR TO SUCH TRANSFER FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION TO SUCH EFFECT. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE GOOD DELIVERY IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA."

and provided that if any of the Purchased Shares are being sold by the Investor in an off-shore transaction and in compliance with the requirements of Rule 904 of Regulation S, the legend set forth above may be removed by providing such evidence as the Corporation or its transfer agent may from time to time reasonably prescribe (which may include an opinion of counsel reasonably satisfactory to the Corporation and its transfer agent), to the effect that the sale of the Purchased Shares is being made in compliance with Rule 904 of Regulation S;

and provided further, that if any of the Purchased Shares are being sold pursuant to Rule 144 of the U.S. Securities Act and in compliance with any applicable State securities laws, the legend may be removed by delivery to the Corporation's transfer agent of an opinion reasonably satisfactory to the Corporation and its transfer agent to the effect that the legend is no longer required under applicable requirements of the U.S. Securities Act and State securities laws;

(d)the Corporation may make a notation on its records or instruct the registrar and transfer agent of the Corporation in order to implement the restrictions on transfer set forth and described herein and the subscription;

(e)the Investor understands and agrees that the financial statements of the Corporation have been prepared in accordance with International Financial Reporting Standards, which differ in some respects from United States generally accepted accounting principles, and thus may not be comparable to financial statements of United States companies;

(f)the Investor understands that the Purchased Shares are "restricted securities" under applicable federal securities laws and that the U.S. Securities Act and the rules of the SEC provide in substance that the Investor may dispose of the Purchased Shares only pursuant to an effective registration statement under the U.S. Securities Act or an exemption therefrom, and, other than as set out herein or in the Investor Rights Agreement, the Investor understands that the Corporation has no obligation to register the offer or sale of any of the Purchased Shares or to take action so as to permit sales pursuant to the U.S. Securities Act (including Rule 144 thereunder). Accordingly, the Investor understands that absent registration, under the rules of the SEC, the Investor may be required to hold the Purchased Shares indefinitely or to transfer the Purchased Shares in the United States or to U.S. Persons in "private placements" which are exempt from registration under the U.S. Securities Act, in which event the transferee may acquire "restricted securities" subject to the same limitations as in the hands of the Investor. As a consequence, the Investor understands that it must bear the economic risks of the investment in the Purchased Shares for an indefinite period of time;

(g)the Investor understands and acknowledges that the Corporation is not obligated to remain a "foreign issuer" (as defined in Rule 902(e) of Regulation S);

(h)the Investor understands and agrees that there may be material tax consequences to the Investor of an acquisition, disposition or exercise of any of the Purchased Shares, and the Corporation gives no opinion and makes no representation with respect to the tax consequences to the Investor under United States, state, local or foreign tax law of the Investor's acquisition or disposition of such Purchased Shares, and in particular, no determination has been made whether the Corporation will be a "passive foreign investment company" ("PFIC") within the meaning of Section 1291 of the United States Internal Revenue Code (the "Code"), provided, however, the Corporation agrees that it shall provide to the Investor, upon written request, all of the information that would be required for United States income tax reporting purposes by a United States security holder making an election to treat the Corporation as a "qualified electing fund" for the purposes of the Code, should the Corporation determine that the Corporation is a PFIC in any calendar year following the Investor's purchase of the Purchased Share; and

(i)the funds representing the Tranche 2 Subscription Price which will be advanced by the Investor to the Corporation hereunder will not represent proceeds of crime for the purposes of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act (the "PATRIOT Act") and the Investor acknowledges that the Corporation may in the future be required by law to disclose the Investor's name and other information relating to the subscription and the Investor's subscription hereunder, on a confidential basis, pursuant to the PATRIOT Act, and that no portion of the Tranche 2 Subscription Price to be provided by the Investor (i) has been or will be derived from or related to any activity that is deemed criminal under the laws of the United States of America, or any other jurisdiction, or (ii) is being tendered on behalf of a person or entity who has not been identified to or by the Investor, and it shall promptly notify the Corporation if the Investor discovers that any of such representations ceases to be true and provide the Corporation with appropriate information in connection therewith.

* * * * * * *

The representations, warranties, statements and certification made in this Certificate are true and accurate as of the date of this Certificate.

Capitalized terms not specifically defined in this Certificate have the meaning ascribed to them in the subscription to which this Certificate is attached.

The Investor acknowledges and agrees that the Corporation will and can rely on this Certificate in connection with the Investor's subscription.
