The TEP shall be fully “grossed-up” for tax purposes such that after taking into account the gross-up (which gross-up or related portions will be paid as set forth below and may or may not be made at the same time as the related reimbursement of relocation costs), the amount of the various TEP and other payments pursuant to this Section shall have included the full amount of the TEP and related taxes attributable to the payment of the TEP and any taxes on the gross-up amount. The amount of any gross-up payments under this Section shall be calculated by the Company in good faith and Employee will promptly provide the Company with any information reasonably requested to calculate the gross-up amount(s). Any gross-up amounts due under this Section will be paid, subject to Section 9.9 of this Agreement, as soon as practicable upon the calculation of such amounts. If the Company, in consultation with its outside tax advisors, determines it is necessary or appropriate for tax optimization, the Company will pay or otherwise remit the TEP in advance of the applicable date in which the compensation is earned.

3.12Tax Preparation Support. For the period beginning on the Start Date and ending on the two-year anniversary of Employee’s permanent relocation to the Vancouver, British Columbia metropolitan area in compliance with the Relocation Requirement, the Company will arrange for tax preparation assistance for the Employee and either (i) pay the tax

preparation provider directly or (ii) reimburse Employee up to a maximum of $5,000 (USD) per year for the reasonable additional expenses Employee incurs in such year in connection with the preparation Employee’s tax return as a result of Employee’s performing services for the Company and/or Parent in Canada as a United States citizen.

Any such expense that is properly substantiated in accordance with the previous sentence will be reimbursed to Employee, less applicable withholdings, via check or electronic funds transfer by the thirtieth (30th) day following the date of receipt by the Company of Employee’s written substantiation (and in no event later than March 15 of the year following the year in which it is incurred). Employee acknowledges that such reimbursements may be taxable to Employee and subject to withholding.

and the Employee agrees that the obligations in Sections 6.1 and 6.2, together with the Employee’s other obligations under this Agreement, are reasonably necessary for the protection of the Company’s good will, trade secrets and proprietary interests and that given the Employee’s general knowledge and experience they would not prevent the Employee from being gainfully employed if the employment relationship between the Employee and the Company were to end. The Employee further confirms that the geographic scope of the obligation in Section 6.2 is reasonable given the nature of the market for the products and business of the Company. The Employee also agrees that the obligations in Sections 6.1 and 6.2 are in addition to the confidentiality and non-disclosure obligations provided for in this Agreement.

6.4Conflict of Interest. The Employee recognizes that the Employee is employed by the Company in a position of responsibility and trust and agrees that during the Employee’s employment with the Company, the Employee will not engage in any activity or otherwise put the Employee in a position which conflicts with the Company’s or Parent’s interests. Without limiting this general statement, the Employee agrees that during the Employee’s employment with the Company, the Employee will not knowingly lend money to, guarantee the debts or obligations of or permit the name of the Employee or any part thereof to be used or employed by any corporation or firm which directly or indirectly is engaged in or concerned with or

interested in any Business in competition with the Business of the Company or Parent unless the Employee receives prior written authorization from the Company.

6.5Acknowledgments. The Employee acknowledges that as of the date of this Agreement:

7.1Application to the British Columbia Supreme Court or the Federal Court of Canada. In the event of a breach or threatened breach by the Employee of any of the provisions of Article 5 or Article 6, the Company will be entitled to injunctive relief restraining the Employee from breaching such provisions, as set forth in this Agreement. Nothing in this Agreement precludes the Company from obtaining, protecting or enforcing its intellectual property rights, or enforcing the Employee’s fiduciary, non-competition, non-solicitation, confidentiality or any other post-employment obligations in a court of competent jurisdiction, or from pursuing any other remedy available to it for such breach or threatened breach, including the recovery of damages from the Employee.

7.2Severability and Limitation. All agreements and covenants contained herein are severable and, in the event any of them will be held to be invalid by any competent court, this Agreement will be interpreted as if such invalid agreements or covenants were not contained herein. Should any court or other legally constituted authority determine that for any such agreement or covenant to be effective that it must be modified to limit its duration or scope, the parties hereto will consider such agreement or covenant to be amended or modified with respect to duration and scope so as to comply with the orders of any such court or other legally constituted authority or to be enforceable under the laws of the Province of British Columbia, and as to all other portions of such agreement or covenants they will remain in full force and effect as originally written.

8.1Mediation/Arbitration. In the event of a dispute hereunder which does not involve the Company seeking a court injunction or remedy pursuant to Article 7, such dispute shall be mediated and, if necessary, arbitrated pursuant to the terms of this Article (the “Med/Arb Agreement”).

8.2The parties will work in good faith and in confidence to resolve any disputes that arise in connection with this Agreement. The parties agree to conduct in good faith at least two meetings (the “Meetings”) to seek resolution to a dispute before delivering a notice to mediate.

8.3Where a dispute arises out of or in connection with this Agreement that cannot be resolved by the parties through the Meetings, the parties agree to seek a confidential settlement of such dispute by mediation followed, if necessary, by arbitration.

8.4At any time after a dispute has been raised and no resolution has been achieved through the Meetings, either party may give written notice to the other party requesting mediation of the dispute (the “Mediation Notice”) by a single mediator. If the parties cannot agree on a mediator within fourteen (14) days after delivery of the Mediation Notice, then either party may make application to the British Columbia Mediator Roster Society to appoint one. The mediation will be held in Vancouver, British Columbia and the costs of mediation will be shared equally between the parties.

8.5If the parties are unable to reach a mediated settlement within 120 days after delivery of the Mediation Notice, either of the parties may submit the dispute to binding arbitration by giving written notice to the other party and the mediator requesting arbitration of the dispute (the “Arbitration Notice”) by a single arbitrator (the “Arbitrator”). Within fourteen (14) days of the delivery of the Arbitration Notice, the parties will select the Arbitrator. In the event the parties do not agree on an arbitrator, either party may apply to the BC Supreme Court to have one appointed. With input from the parties, the Arbitrator will determine and notify the parties of the rules of and timetable for arbitration. The Arbitrator will hear the submissions of the parties in accordance with such procedures as he or she may establish, and shall use reasonable best efforts to render a decision within sixty (60) days after the date of receiving or hearing the parties’ final submissions. The decision of the Arbitrator shall be final and binding on the parties involved in the dispute and shall not be subject to appeal. The arbitration will be held in Vancouver, British Columbia, and the costs of arbitration will be shared equally between the parties.

9.3Construction. The parties acknowledge that each party and its respective counsel have had the opportunity to independently review and negotiate the terms and conditions of this Agreement, and that the normal rule of construction to the effect that any ambiguities are to be construed against the drafting party will not be employed in the interpretation of this Agreement or any exhibits or amendments hereto.

9.8Governing Law. This Agreement will be governed by and construed, enforced and interpreted exclusively in accordance with the laws of the Province of British Columbia and the applicable laws of Canada therein, except as specified in Articles 5.3 and 8 above.

9.9Code Section 409A. The parties intend that payments and benefits under this Agreement to be exempt from or comply with Internal Revenue Code Section 409A and the regulations and guidance thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement will be interpreted to be in compliance with Code Section 409A.

(a)To the extent that any provision hereof is modified in order to comply with Code Section 409A, such modification will be made in good faith and will, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Employee and the Company of the applicable provision without violating the provisions of Code Section 409A. In no event whatsoever will the Company be liable for any additional tax, interest or penalty that may be imposed on the Employee by reason of Code Section 409A or damages for failing to comply with Code Section 409A. For purposes of compliance with Code Section 409A, each payment subject to Code Section 409A (or intended to satisfy an exception under Code Section 409A including payment under Sections 4.2(b) and 4.2(d) of this Agreement) will be treated as a separate payment, and the right to a series of installment payments under this Agreement will be treated as a right to a series of separate payments.

(b)To the extent that payments under the Agreement that are payable upon the Employee’s termination of employment constitute “nonqualified deferred compensation” that is subject to Code Section 409A, a termination of employment will not be deemed to have occurred for purposes of any provision of this Agreement providing for any such payment upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms means “separation from service.”

(c)Notwithstanding any other payment schedule provided herein to the contrary, if the Employee is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A (or the Company has opted to treat all employees as “specified employees”), then any payment that is considered “nonqualified deferred compensation” under Code Section 409A payable on account of a “separation from service” will not be made until the date which is the earlier of:

(i)the expiration of the six (6)-month period measured from the date of such “separation from service” of the Employee, and

(ii)the date of the Employee’s death, to the extent required under Code Section 409A (the delay referred to as the “Delay Period”).

(d)Upon the expiration of the Delay Period, all payments delayed pursuant to this Section 9.9 (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) will be paid to the Employee in a lump sum (with no accrued interest), and all remaining payments due under this Agreement will be paid or provided in accordance with the normal payment dates specified for them herein.

(e)Any reimbursements by the Company to the Employee of any eligible expenses under this Agreement that are not excludable from the Employee’s income for U.S. federal income tax purposes (the “Taxable Reimbursements”) shall be made by no later than the last day of the taxable year of the Employee

following the year in which the expense was incurred. The amount of any Taxable Reimbursements, and the value of any in-kind benefits to be provided to the Employee, during any taxable year of the Employee shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year of the Employee. The right to Taxable Reimbursement, or in-kind benefits, shall not be subject to liquidation or exchange for another benefit.

(f)Tax Equalizations and Tax Gross-Up Payments.  Any tax equalization payments (within the meaning of U.S. Treasury Regulation Section 1.409A 1(b)(8)(iii)) will be made no later than the end of the second calendar year beginning after the calendar year in which Employee’s United States Federal income tax return is required to be filed (including any extensions) for the year to which the compensation subject to the tax equalization payment relates, or, if later, the second calendar year beginning after the latest calendar year in which Employee’s non-U.S. tax return or payment is required to be filed or made for the year to which the compensation subject to the tax equalization payment relates.  Where such payments arise due to an audit, litigation or similar proceeding, the payments will be made, as required by and in accordance with Treasury Regulation Section 1.409A-3(i)(1)(v), no later than the last day of the calendar year that immediately follows the calendar year in which Employee remits the related taxes to the taxing authorities.  If Employee fails to provide the required receipts and tax documentation when requested, Employee will be responsible for paying any and all penalties and interest that may be incurred due to a late tax filing. Further, in no event will tax equalization payments exceed the amounts permitted by Treasury Regulation Section 1.409A-1(b)(8)(iii). Any tax gross-up payment (within the meaning of U.S. Treasury Regulation Section 1.409A-3(i)(1)(v)) that is payable to Employee and is not otherwise exempt from, and does not otherwise comply with, Section 409A shall be made no later than the end of the calendar year next following the calendar year during which the related taxes are remitted to the taxing authorities by or on behalf of Employee.  In addition, a right to the reimbursement of expenses incurred due to a tax audit or litigation addressing the existence or amount of a tax liability, whether U.S. federal, state, local, or non-U.S., will be made no later than the end of the calendar year following the calendar year in which the taxes that are the subject of the audit or litigation are remitted to the taxing authority, or where as a result of such audit or litigation no taxes are remitted, the end of the calendar year following the calendar year in which the audit is completed or there is a final and nonappealable settlement or other resolution of the litigation. If Employee’s taxable year is not a calendar year, all timing requirements in this paragraph referring to “calendar year” will instead refer to Employee’s taxable year.

(a)In the event that the severance or change in control-related or other payments or benefits provided for in this Agreement or otherwise payable to Employee (collectively, the “Payments”) (x) constitute “parachute payments” within the meaning of Section 280G of the Code, and (y) but for this Section 9.10, would

be subject to the excise tax imposed by Section 4999 of the Code, then such payments or benefits will be either:

(i) delivered in full, or

(ii) delivered as to such lesser extent which would result in no portion of such benefits being subject to excise tax under Section 4999 of the Code,

whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999 of the Code, results in the receipt by the Employee on an after-tax basis, of the greatest amount of Payments, notwithstanding that all or some portion of such Payments may be taxable under Section 4999 of the Code. If a reduction in Payments constituting “parachute payments” is necessary so that Payments are delivered to a lesser extent, reduction will occur in the following order: (i) cancellation of equity awards granted “contingent on a change in ownership or control” (within the meaning of Section 280G of the Code); (ii) a pro rata reduction of (A) cash payments that are subject to Code Section 409A as deferred compensation and (B) cash payments not subject to Code Section 409A; (iii) a pro rata reduction of (A) employee benefits that are subject to Section 409A as deferred compensation and (B) employee benefits not subject to Section 409A; and (iv) a pro rata cancellation of (A) accelerated vesting of equity awards that are subject to Code Section 409A as deferred compensation and (B) equity awards not subject to Code Section 409A. If acceleration of vesting of equity awards is to be cancelled, such acceleration of vesting will be cancelled in the reverse order of the date of grant of Employee’s equity awards. In no event will Employee have any discretion with respect to the ordering of payment reductions.

(b)Unless the Company and Employee otherwise agree in writing, any determination required under this Section 9.10 will be made in writing by a nationally recognized firm of independent public accountants selected by the Company (the “Accountants”), whose determination will be conclusive and binding upon Employee and the Company for all purposes. For purposes of making the calculations required by this Section 9.10, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Employee will furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section 9.10. The Company will bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 9.10.
