|5.2 | Consequences
    of Termination.Upon termination of the Executive’s employment for any reason, the Corporation will reimburse the
    Executive’s expenses properly incurred until the date his employment ceases and pay (i) subject to Section 5.3, a lump
    sum payment of $700,000 on the sixtieth (60th) day following the date of the Executive’s termination of employment,
    payable (at the Executive’s discretion) in the form of cash or a number of shares of the Corporation’s common
    stock having a then-current Fair Market Value (as defined in the Corporation’s 2002 Stock Incentive Plan, as amended)
    equal to $700,000 (rounded to the nearest whole share) (the “Severance Payment”), and (ii) the Executive’s
    base salary and vacation pay accrued until the date his employment ceases. The termination of the Executive’s employment
    terminates any director or officer positions the Executive may hold pursuant to Section 2.2, and the Executive agrees to sign
    any documentation necessary to give effect to this Section 5.2, or to give effect to any pro forma resolutions of the Corporation
    in respect of the period prior to termination of his employment.

|9.1 | Consideration.The Executive acknowledges that he has and will receive good and valuable consideration including, without limitation,
    the consideration set out in this Agreement in exchange for his compliance with his obligations in Sections 6, 7 and 8, and
    that the Corporation would not have provided the Executive such consideration without the Executive’s commitment to
    such obligations.

|9.2 | Defences.The Executive agrees that all restrictions in Sections 6, 7 and 8 are necessary and fundamental to the protection of the
    business carried on by the Corporation and that all such restrictions are reasonable and valid, and the Executive waives all
    defences of the Executive to the strict enforcement thereof by the Corporation.

|9.3 | Injunctive
    Relief.The Executive acknowledges that a breach by the Executive of any of his obligations in Sections 6, 7 and 8 will
    result in the Corporation suffering irreparable harm, which cannot be calculated or fully or adequately compensated by recovery
    of damages alone. Accordingly, the Executive agrees that the Corporation shall be entitled to interim and permanent injunctive
    relief without proof of actual damages, specific performance and other equitable remedies, in addition to any other relief
    to which the Corporation may become entitled.
