WHEREAS the Company desires to hire the Employee;

AND WHEREAS the Employee agrees to accept employment with the Company on the terms and conditions set out in this agreement;

NOW THIS AGREEMENT WITNESSES that in consideration of the premises and mutual covenants herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by both parties, the parties hereby covenant and agree with each other as follows:

1. TERM

1.1 This agreement will start on the Effective Date and continue for an indefinite term unless terminated by either party in accordance with the terms of this agreement.

2. POSITION AND DUTIES

2.1 The Employee will be employed as Chief Development Officer, and report to the Chief Executive Officer. The Employee will perform such duties and assume such responsibilities inherent in and consistent with this position, including any reasonable additional duties and responsibilities as the Company may require and assign to him from time to time.

2.2 The Employee agrees to act as a director or officer of the Company or any of its affiliates (as defined in the British Columbia Business Corporations Act) if so requested by the Company and agrees that his Base Salary (as defined below) is adequate consideration for him so acting.

2.3 The Employee will be based out of Perth, Western Australia, or such other location as mutually agreed between the parties from time to time. Notwithstanding the Employee’s location, the Employee acknowledges that the nature of his employment requires international travel to places other than his regular place of employment. All travel and related expenses must be incurred in accordance with the Company’s travel expense policy. Subject to DeepGreen’s work commitments, some flexible work arrangements can be made, and the Employee will be able to work from home from time to time provided the Employee has prior approval from the Company’s Chief Executive Officer.

3. CONFLICT OF INTEREST/DUTY OF LOYALTY

3.1 The Employee agrees to act, at all times, in the best interests of the Company. The Employee will not, without the advanced written approval of the Company, directly or indirectly engage in or have an interest in any other enterprise, occupation or profession, or become a principal, agent, director, officer, or employee of another entity which interferes or conflicts with the Employee’s duties and responsibilities to the Company or the interests of the Company.

4. BASE COMPENSATION

4.1 Commencing June 19, 2017 the Company will pay to the Employee an annual salary of AUD$400,000, less applicable deductions (including Australian PAYG withholding tax or such other withholding tax applicable in the jurisdiction where the Employee resides) and paid in accordance with the Company’s usual payroll practices (the “Base Salary”). The Base Salary covers all time worked.

4.2 The Company will review the Employee’s Base Salary on an annual basis. The Company is not obligated to increase the Employee’s Base Salary at any review.

5. SHORT-TERM INCENTIVE PLAN

5.1 The Employee will be eligible to participate in the Company’s short-term incentive plan (the “STIP”) and to be considered for an annual performance incentive bonus under the STIP. STIP targets and performance goals will be set annually (in advance), by the Company’s Chief Executive Officer. Where payable, STIP payments shall be made as soon as practicable following the first quarter of the first financial year following that in which it is earned (and for greater certainty, not when the performance goal is achieved).

All options granted in satisfaction of STIP payments shall be governed by the Company’s stock option plan and any applicable stock option agreement entered into. The ratio of options to cash will not be less than 50% however, by agreement between the CEO and the Employee, the ratio may be adjusted in favour of more options. STIP payments shall be pro-rated for partial years and shall be based on the Employee’s then current Base Salary.

5.3 The exercise price for stock options granted pursuant to any STIP payment shall be determined by the Company’s Board of Directors with reference to (i) the published market on which the greatest volume of trading in the Company’s common shares occurred and the rules of any applicable stock exchange regarding the pricing of stock options; or (ii) if no such published market exists, any and all factors that the Board of Directors considers appropriate in the circumstances at their sole discretion.

5.4 Notwithstanding anything contained in this Section 5, in the event the Company carries out a going public transaction (including without limitation an initial public offering, reverse takeover and/or a transaction with DV Resources Ltd.) (“Going Public Transaction”), the Short Term Incentive Plan will be amended by the Company as necessary to facilitate such going public transaction. This may include an amendment to the terms of any stock options granted under the Short Term Incentive Plan so as to comply with the terms of the listed entities’ stock option plan.

The stock options will be subject to the conditions set forth in the Company’s stock option plan, or in the case the Company carries out a Going Public Transaction, subject to the conditions set forth in the listed entities stock option plan.

6.3 All options granted to the Employee under this section 6 shall be governed by the terms of the Company’s stock option plan and the applicable stock option agreement entered into between the Company and the Employee, or in the case the Company carries out a Going Public Transaction, then subject to the conditions set forth in the listed entity’s stock option plan.
