As a condition precedent to payment of any compensation under Sections ‎7.02 and ‎7.04, the Executive agrees to execute before a witness and deliver to Lithium Nevada a separation agreement and general release of all claims against the LAC Group, their affiliates, subsidiaries and their directors, officers, employees, shareholders and agents, in a form reasonably satisfactory to Lithium Nevada and within the timelines specified by Lithium Nevada. In accordance with the Age Discrimination in Employment Act, if applicable, the Executive will be provided an extended period of time to consider the terms of the release before signing, and no benefits shall be payable until the consideration period and any revocation periods have passed. Except for the Accrued Entitlements in Section ‎7.03, no compensation will be due and payable to the Executive until after the LAC Group receives a fully executed original of such separation agreement and general release, and any applicable revocation periods have expired. Except for the Accrued Entitlements, any compensation due under this Agreement shall be made on the 60th day following separation from service, provided the release is effective on such date and any revocation periods have expired. Lump sum severance shall be paid no later than March 15 of the calendar year following the year in which Executive’s employment is terminated without Cause, or for Good Reason, or due to a Disability, provided that the release described above is effective at such time.

7.07 Section 280G

(a)If any of the payments or benefits received or to be received by the Executive (including, without limitation, any payments or benefits received in connection with a Change in Control including payments that could be made on the Executive’s termination of employment following a Change in Control, whether pursuant to the terms of this Agreement or any other plan, arrangement, or agreement, or otherwise) (all such payments collectively referred to herein as the “280G Payments”) constitute “parachute payments” within the meaning of Section 280G of the Code and will be subject to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), the 280G Payments shall be either: (a) reduced (but not below zero) so that the present value of such total 280G Payments received by Executive will be one dollar ($1.00) less than three (3) times Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code) and so that no portion of such 280G Payments will be subject to the excise tax imposed by Section 4999 of

- 16 -

the Code, or (b) paid in full, whichever of (a) or (b) produces the better net after tax position to Executive (taking into account any applicable excise tax under Section 4999 of the Code and any other applicable taxes). If a reduction in such 280G Payments is to be made pursuant to this section, the 280G Payments shall be reduced in the following order: (i) any portion of the cash severance payable hereunder that is not “nonqualified deferred compensation” for purposes of Code Section 409A; (ii) any benefits continuation valued as parachute payments; (iii) any accelerated vesting of any equity awards; and (iv) any portion of the cash severance payable hereunder and any other cash amounts that are “nonqualified deferred compensation” for purposes of Code Section 409A.

(b)All calculations and determinations under this Section ‎7.07 shall be made by an independent accounting firm or independent tax counsel appointed by the Company (the “Tax Counsel”) whose determinations shall be conclusive and binding on the Company and the Executive for all purposes. For purposes of making the calculations and determinations required by this Section ‎7.07, the Tax Counsel may rely on reasonable, good faith assumptions and approximations concerning the application of Section 280G and Section 4999 of the Code. The Company and the Executive shall furnish the Tax Counsel with such information and documents as the Tax Counsel may reasonably request in order to make its determinations under this Section ‎7.07. The Company shall bear all costs the Tax Counsel may reasonably incur in connection with its services.

Article 8

EXECUTIVE’S OBLIGATIONS FOLLOWING TERMINATION

Upon termination of this Agreement for any reason, the Executive covenants with Lithium Nevada as follows:

8.01 Non-competition

During the term of this Agreement and for 12 months following termination of the Executive’s employment, the Executive shall not accept employment from any company or business entity that is engaged in the Business within the Geographic Area. This Section shall not be construed so as to restrict the Executive’s right to accept employment with or to engage in any business that is not competitive with the Business of Lithium Nevada. Notwithstanding anything to the contrary herein, this Section ‎8.01 shall not (i) apply following a termination of the Executive’s employment due to a resignation for Good Reason with respect to which Section ‎7.04 applies, or (ii) prohibit the Executive from purchasing or owning less than five percent (5%) of the publicly traded securities of any corporation, providing that such ownership represents a passive investment and that the Executive is not a controlling person of, or a member of a group that controls, such corporation.

- 17 -

8.02 Non-solicitation of employees

During the Executive’s employment and for a period of 12 months after termination of the Executive’s employment for any reason, the Executive shall not, directly or indirectly, on the Executive’s own behalf or on behalf of any Person, recruit, solicit, persuade or otherwise induce or attempt to recruit, solicit, persuade or induce any Person who is an employee of Lithium Nevada to terminate their employment with Lithium Nevada.

8.03 Non-disparagement

Subject to Section ‎8.05, during the Executive’s employment and for a period of 12 months following the termination of this Agreement, the Executive shall not make any statement criticizing the LAC Group or impairing the goodwill or reputation of the LAC Group, unless truthful and required by law.

8.04 Extension/reasonableness of restrictive covenants

The period of time applicable to the covenants not to compete and not to solicit will be extended by the duration of any violation by the Executive of such covenants. In addition, the time periods applicable to the covenants not to compete and not to solicit will be extended by the duration of any period of time, after the termination of the Executive’s employment with Lithium Nevada, that Executive is retained as a consultant to Lithium Nevada or an independent contractor by Lithium Nevada (in any capacity).

The Executive agrees that the restrictions of this Agreement are reasonable (in scope, duration, and activity restricted), necessary, and supported by valuable consideration. The Executive further agrees that the restrictions of this Agreement will not prevent him from obtaining adequate and gainful employment upon termination of his employment with the Lithium Nevada (voluntary or involuntary). The Executive also agrees that this Agreement: (i) does not impose on the Executive any restraint that is greater than required for the protection of the Lithium Nevada; (ii) does not impose undue hardship on the Executive; and (iii) imposes restrictions that are appropriate in relation to the valuable consideration supporting the non-competition and non-solicitation covenants.

The Executive acknowledges he has had a fair opportunity and time to independently consult with legal counsel and has been advised or had reasonable opportunity to be advised in all respects concerning the reasonableness and propriety of this Agreement. The Executive understands that his covenants in this Agreement are independent covenants, and the existence of any claim by the Executive against Lithium Nevada under this or any other agreement or otherwise will not excuse the Executive’s breach of any covenant in this Agreement.

8.05 Protected rights

The Executive understands that (a) the Executive will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made in confidence to a United States federal, state, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, (b) the Executive will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade

- 18 -

secret that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal, and (c) an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding if the individual files any document containing the trade secret under seal, and does not disclose the trade secret, except pursuant to court order.

In addition, nothing in this Agreement shall be construed to prohibit the Executive from exercising the Executive’s legal rights with the Equal Employment Opportunity Commission, or any other federal, state or local agency charged with the enforcement of any law applicable to the LAC Group or participating in any investigation or proceeding conducted by such agency. Similarly, nothing in this Agreement shall prohibit the Executive from engaging in activity protected by applicable law. Finally, with respect to sexual assault dispute or sexual harassment dispute, nothing in this Agreement prohibits: (i) disclosure or discussion of conduct, the existence of a settlement involving conduct, or information covered by the terms and conditions of the contract or agreement; or (ii) negative statements about another party that relates to the contract, agreement, claim or case.

8.06 Return of property

At the conclusion of employment, or at Lithium Nevada’s request during employment, the Executive shall promptly return to Lithium Nevada any LAC Group property in the Executive’s possession or control, including but not limited to any Confidential Information, assets, or any other documents or information, whether in physical or electronic form.

Article 10

PRIVACY

10.01 Personal information

The Executive acknowledges that the LAC Group may collect, use and/or disclose the Executive’s personal information where it is reasonable for the purposes of establishing, managing or terminating the employment relationship, and in accordance with applicable privacy legislation and LAC Group policy.

The Executive further acknowledges that, in the course of employment, the Executive may obtain or control the personal information of employees, contractors, suppliers, customers, affiliates and other third parties. The Executive agrees to maintain and manage any such personal information in accordance with applicable LAC Group policy and legal requirements, and to immediately notify the LAC Group in the event of any unauthorized collection, use or disclosure of personal information.

Article 11

GENERAL PROVISIONS

11.01 Entire agreement

Except for any other agreements mentioned above, which are incorporated by reference, this Agreement constitutes the entire agreement between the parties relating to its subject matter. This Agreement supersedes either previous discussions or agreements or both between the parties. There are no representations, covenants, or other terms other than those set forth in this Agreement.

11.02 Further assurances

Each party shall sign (or cause to be signed) all further documents, do (or cause to be done) all further acts, and provide all reasonable assurances as may be necessary or desirable to give effect to this Agreement.

11.03 Amendment

This Agreement may only be amended by a written document signed by each of the parties.

11.04 Binding effect

This Agreement inures to the benefit of and binds the parties and their respective heirs, executors, administrators and other legally appointed representatives, successors, and permitted assigns.

11.05 Assignment

The Executive expressly agrees that this Agreement—specifically including the non-compete, non-solicitation and confidentiality provisions—may be assigned by Lithium Nevada to another New LAC subsidiary, or affiliate of the LAC Group, or a successor-in-interest to the LAC Group’s

- 20 -

business whether by name change, sale of assets, stock, merger or otherwise, and the Executive consents to any such assignment. The assignment shall also automatically have the effect of adding the assignee as a party to this Agreement, including adding the assignee to all provisions that survive the termination of this Agreement and shall expand all such surviving provisions (e.g., non-competition, non-disclosure and non-solicitation) accordingly. The Executive expressly agrees that 5% of the Executive’s Base Salary is in consideration of the Executive’s consent to the right of the LAC Group’s successors, affiliates, and assigns to enforce the provisions of this Section ‎11.05.

For the avoidance of doubt, such an assignment does not constitute Termination without Cause, Good Reason for the Executive’s resignation, or a Change in Control under this Agreement, and therefore, does not entitle the Executive to the severance benefits outlined in Sections ‎7.02 and ‎7.04.

11.06 Notice

To be effective, a notice must be in writing and delivered (a) personally, either to the individual designated below for that party or to an individual having apparent authority to accept deliveries on behalf of that individual at its address set out below, or (b) by registered mail, or (c) by electronic mail to the address or electronic mail address set out opposite the party’s name below or to any other address or electronic mail address for a party as that party from time to time designates to the other parties in the same manner:

11.07 Code Section 409A

For purposes of this Agreement, a termination of employment will be determined consistent with the rules relating to a “separation from service” as defined in Section 409A of the Code and the regulations thereunder (“Section 409A”). Notwithstanding anything else provided herein, to the extent any payments provided under this Agreement in connection with Executive’s termination of employment constitute deferred compensation subject to Section 409A, and Executive is deemed at the time of such termination of employment to be a “specified employee” under Section 409A, then such payment shall not be made or commence until the earlier of (i) the expiration of the 6-month period measured from Executive’s separation from service from the LAC Group or (ii) the date of Executive’s death following such a separation from service; provided, however, that such deferral shall only be effected to the extent required to avoid adverse tax treatment to Executive including, without limitation, the additional tax for which Executive would otherwise be liable under Section 409A(a)(1)(B) in the absence of such a deferral. The first payment thereof will include a catch-up payment covering the amount that would have otherwise been paid during the period between Executive’s termination of employment and the first payment date but for the application of this provision, and the balance of the installments (if any) will be payable in accordance with their original schedule. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A, the provision will be read in such a manner so that all payments hereunder comply with Section 409A. To the extent any payment under this Agreement may be classified as a “short-term deferral” within the meaning of Section 409A, such payment shall be deemed a short-term deferral, even if it may also qualify for an exemption from Section 409A under another provision of Section 409A. Payments pursuant to this Section are intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. Except as otherwise expressly provided herein, to the extent any expense reimbursement or the provision of any in-kind benefit under this Agreement is determined to be subject to Section 409A of the Code, the amount of any such expenses eligible for reimbursement, or the provision of any in-kind benefit, in one calendar year shall not affect the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation applicable to medical expenses), in no event shall any expenses be reimbursed after the last day of the calendar year following the calendar year in which the Executive incurred such expenses, and in no event shall any right to reimbursement or the provision of any in-kind benefit be subject to liquidation or exchange for another benefit.

11.08 Governing law/venue

The laws of the State of Nevada shall govern this Agreement. Venue for any disputes under this Agreement shall be in Washoe County, Nevada. This venue provision is mandatory.

11.09 Submission to jurisdiction

The parties irrevocably submit to personal jurisdiction in Nevada and Washoe County.

- 22 -

11.10 Counterparts

This Agreement may be signed in any number of counterparts, each of which is an original, and all of which taken together constitute one single document. Counterparts may be transmitted by fax or in electronically scanned form.

11.11 Remedies/attorney’s fees

The Executive acknowledges and agrees that monetary damages may not be a sufficient remedy for any breach by the Executive of the obligations set out in Articles ‎‎5 and 8 of this Agreement, and that in addition to all other remedies available at law, Lithium Nevada shall be entitled to seek injunctive or other equitable relief as a remedy for any such breach. If the Executive breaches this Agreement, Lithium Nevada shall be entitled to recover its reasonable attorney’s fees and costs incurred as a result of the breach and/or as a result of pursuing enforcement of this Agreement.
