The executive represents and warrants to the Corporation that he is free to enter this Agreement and that he is not subject to any obligation or restriction (statutory, contractual, or at common law) which would prevent or interfere with the performance of all of his obligations hereunder.

ARTICLE IV - COMPENSATION AND BENEFITS

4.1 Base Salary. The Corporation shall pay the Executive a base salary of U.S.$500,000 annually, paid in such installments and at such times and otherwise in accordance with the Corporation’s payroll practices. The Executive’s base salary will be reviewed annually by the Corporation for consideration of an increase, if appropriate, in its discretion.

4.2 Benefits. Subject to eligibility, the Executive shall be eligible to participate in all benefit and fringe benefit programs, including group benefit plans and policies provided by the Corporation to similarly situated executives of the Corporation (currently including medical (including the Global Medical Assistance program), prescription, dental, disability, life and AD&D insurance), as such programs, plans and policies may be amended from time to time. The Corporation shall also reimburse an amount of up to a maximum of U.S.$800 per year on account of the costs incurred by the Executive in connection with his annual medical examination.

4.3 Cash Bonus. For each fiscal year of the Executive’s employment with the Corporation under this Agreement, the Executive shall be eligible for an annual bonus of up to 50% of the annual base salary paid to the Executive during such year. The amount of such cash bonus shall depend upon the achievement by the Executive and/or the Corporation of reasonable management objectives to be established by the Board in consultation with the Executive at least thirty (30) days prior to the beginning of the relevant fiscal year. Any cash bonus for a relevant fiscal year shall be payable in one lump sum upon approval of the Board, which shall be obtained by the Corporation on or about January 31 of the ensuing year, and paid at the next regular payroll period after Board approval, unless cash flow is an issue in which case the Board may elect to pay the bonus in equal monthly instalments over no more than four (4) months.

4.4 Tax Equalization. The Corporation and the Executive intend that the income taxes payable by the Executive that are attributable to amounts or other compensation payable under this Agreement shall not exceed the income taxes payable to the United States of America and the State of California (or such other State to which the Executive may owe income tax as a result of his residence or citizenship) that are or would be attributable to amounts or other compensation payable to the Executive pursuant to this Agreement. As

such, in the calendar year following each calendar year during which the Executive receives compensation from the Corporation pursuant to this Agreement (including amounts referred to in this Section 4.4), the Corporation shall pay to the Executive an amount representing the estimated Equalization Amount, if any, as estimated by the Corporation’s tax advisors (currently Ernst & Young LLP). For the purposes of this Section 4.4, the “Equalization Amount” shall be an amount equal to the difference between (i) the aggregate income taxes due and payable by the Executive in respect of amounts or other compensation received by the Executive from the Corporation to the United States of America, the State of California (or such other State to which the Executive may owe income tax as a result of his residence or citizenship), Canada and any applicable province or other jurisdiction in Canada by the Executive for such year due to his employment with the Corporation and taking into account any foreign tax credit or deduction available to the Executive and (ii) the aggregate of such income taxes that would otherwise have been due and payable to the United States of America and the State of California (or such other State to which the Executive may owe income tax as a result of his residence or citizenship) by the Executive for such year had the Executive not been required to pay income taxes in Canada or any province or other jurisdiction in Canada computed without regard to any foreign tax credit or deduction available to the Executive. After the end of each relevant calendar year, the Corporation’s tax advisors (currently Ernst & Young LLP) shall determine the actual Equalization Amount and the parties will make any appropriate adjustments. In addition, the Corporation shall pay to the Executive an additional amount (commonly known as gross-up) such that the net amount retained by the Executive after payment of any and all income taxes (including the United States of America, the State of California, Canada and any applicable province or other jurisdiction in Canada or the United States of America) on the Equalization Amount shall not be less than the amount the Executive would have received if such income taxes had not been paid. For greater certainty, any interest or penalty payable by the Executive by reason of the Executive failing to file appropriate tax returns on a timely or correct basis shall not be taken into account to compute the Equalization Amount and shall be at the sole expense of the Executive.

4.5 Options. Subject to the rules of the TSX, upon commencement of the Executive’s employment with the Corporation, the Corporation shall grant to the Executive options to purchase up to 9,538,000 common shares in the capital of the Corporation (representing approximately 3% of the currently issued and outstanding common shares in the capital of the Corporation). Subject to the approval of the shareholders of the Corporation authorizing the increase of the number of common shares in the capital of the Corporation available for option grants under the Stock Option Plan (which approval shall be sought at the earlier of (i) a special meeting of shareholders called to approve a private placement; or (ii) the Corporation’s next Annual General Meeting), the Executive will be entitled to be granted options entitling him to purchase up to an additional 3,179,450 common shares in the capital of the Corporation (representing approximately 1% of the currently issued and outstanding common shares in the capital of the Corporation). It is also the Corporation’s intention to maintain the Executive’s option entitlement at approximately 4% of the issued and outstanding common shares in the capital of the Corporation after the next round of financing, subject to appropriate shareholder approval. Such option grants shall be in an exercise price equal to the Fair

Market Price (as such term is defined in the Stock Option Plan) per share at the time of the applicable grant, with 20% of such options vesting on the date of grant and tranches of 20% vesting on each anniversary thereof. The Executive may be granted additional stock options on an annual basis or such other basis as may be determined from time to time by the Board, in its sole discretion.

4.6 Vacation. The Executive shall be entitled to vacation in accordance with the Corporation’s vacation policy for management, currently four (4) weeks’ paid vacation per calendar year, such vacation to extend for such periods and to be taken at such intervals as shall be appropriate and consistent with the proper performance of the Executive’s duties and is agreed upon between the Executive and the Corporation. Accumulated vacation time or pay may not be carried forward except with the prior approval of the Corporation. Such vacation shall be prorated for the period between the Commencement Date and December 31, 2012.

4.7 Reimbursement of Expenses. Upon presentation of proper receipts or other proof of expenditure and subject to such reasonable guidelines or limitations provided by the Corporation from time to time, the Corporation shall reimburse the Executive for all reasonable and necessary expenses actually incurred by the Executive directly in connection with the business affairs of the Corporation and the performance of his duties hereunder, including return trips (in economy class) to the USA for personal reasons. The Executive shall comply with such reasonable limitations and reporting requirements with respect to such expenses as the Board may establish from time to time.

4.8 Directors’ and Officers’ Liability Insurance. During the term of his employment, the Executive shall be entitled to, and the Corporation shall maintain in effect and pay for, coverage under the Corporation’s directors’ and officers’ liability insurance policy, in an amount and to an extent not less than the level of coverage that the Corporation provides to its directors and other senior executive management.

4.9 Compensation Review. Notwithstanding any other provision of this Agreement, it is agreed that the Corporation will review and consider an upward adjustment of the total compensation of the Executive hereunder (including base salary, bonus and stock options) by no later than January 31, 2013, and on an annual basis thereafter by no later than January 31 of each subsequent year, in each case retroactive to January 1 of the relevant year.
