In addition, the Company shall have no obligation to issue any Common Shares pursuant to the Plan unless such Common Shares shall have been duly listed, upon official notice of issuance, with all stock exchanges on which the Common Shares are listed for trading. Common Shares issued and sold to Participants pursuant to the exercise of Options may be subject to limitations on sale or resale under applicable securities laws.

- 7 - (c)
      The Plan does not give any Participant or any employee of the Company or any of its Associated or Subsidiary companies the right or obligation to or to continue to serve as a director, officer or employee, as the case may be, of the Company or any of its Associated or Subsidiary companies. The awarding of Options to any Eligible Person is a matter to be determined solely in the discretion of the Board. The Plan shall not in any way fetter, limit, obligate, restrict or constrain the Board with regard to the allotment or issue of any Common Shares or any other securities in the capital of the Company or any of its subsidiaries other than as specifically provided for in the Plan.(d)
      No fractional Common Shares shall be issued upon the exercise of Options granted under the Plan and, accordingly, if a Participant would become entitled to a fractional Common Share upon the exercise of an Option, such Participant shall only have the right to purchase the next lowest whole number of Common Shares and no payment or other adjustment will be made with respect to the fractional interest so disregarded. 2.
      OPTIONS2.1
      Grants Subject to the provisions of the Plan, the Board shall have the authority to determine the limitations, restrictions and conditions, if any, in addition to those set forth in section 2.3 hereof, applicable to the exercise of an Option, including, without limitation, the nature and duration of the restrictions, if any, to be imposed upon the sale or other disposition of Common Shares acquired upon exercise of the Option, and the nature of the events, if any, and the duration of the period in which any Participant’s rights in respect of Common Shares acquired upon exercise of an Option may be forfeited. An Eligible Person may receive Options on more than one occasion under the Plan and may receive separate Options on any one occasion. 2.2
      Option Price The Board shall establish the Option price at the time each Option is granted, which shall, as long as the Company’s Common Shares are listed on the TSX Venture Exchange, be not less than the Discounted Market Price. At such time as the Company’s Common Shares are listed on the TSX Exchange, the Option price shall be not less than the Fair Market Value. The Option price shall be subject to adjustment in accordance with the provisions of section 1.4(f) hereof. 2.3
      Exercise of Options (a)
      Subject to section 2.3(b), the Options granted must expire not later than: (i)
      as long as the Company’s Common Shares are listed on Tier 2 of the TSX Venture Exchange, a maximum of 5 years from the date of grant; or(ii)
      at such time as the Company’s Common Shares are listed on Tier 1 of the TSX Venture Exchange or on the TSX Exchange, a maximum of 10 years from the date of grant. (b)
      In the event that the expiration date of an Option should fall within a black-out period, as may be imposed from time to time under the Company’s insider trading policy which prohibits trading in securities of the Company, then the


---

- 8 - expiration date of the affected Option shall be automatically extended for a period of ten (10) business days following the date that the black-out period is lifted.(c)
      Options will vest at the discretion of the Board, as determined at the time of each grant, provided that options granted to consultants performing investor relations activities shall vest in stages over 12 months with no more than one quarter of the options vesting in any three month period.(d)
      Options shall not be assignable or transferable by the Participant otherwise than by will or the laws of descent and distribution, and shall be exercisable during the lifetime of a Participant only by the Participant and after death only by the Participant’s legal representative.(e)
      Subject to section 2.3(a) and except as otherwise determined by the Board: (i)
      if a Participant ceases to be an Eligible Person which, for the purposes of this subsection does not include persons engaged in investor relations activities, for any reason whatsoever other than death, each Option held by the Participant will cease to be exercisable no more than 90 days after the Termination Date. Options granted to Participants engaged in investor relations activities must expire within 30 days after the Participant ceases to be employed to provide investor relations activities. If any portion of an Option is not vested by the Termination Date, that portion of the Option may not under any circumstances be exercised by the Participant. Without limitation, and for greater certainty only, this provision will apply regardless of whether the Participant was dismissed with or without cause and regardless of whether the Participant received compensation in respect of dismissal or is entitled to a period of notice of termination which would otherwise have permitted a greater portion of the Option to vest with the Participant;(ii)
      if a Participant dies, the legal representative of the Participant may exercise the Participant’s Options within one year after the date of the Participant’s death, but only to the extent the Options were by their terms exercisable on the date of death;(iii)
      the retirement of any Participant who is a director of the Company or any Subsidiaries or Associate companies at any annual general meeting of the Company or such Subsidiaries as required by the constating documents of the Company or Subsidiaries, as the case may be, shall not result in the termination of the Option granted to such Participant provided that such Participant is re-elected at such annual general meeting as a director of the Company or such Subsidiary, as the case may be;(iv)
      the change in the duties or position of a Participant or the transfer of such Participant from a position with the Company to a position with an Subsidiary, or vice-versa, shall not trigger the termination of such Participant’s Option provided such Participant remains a director, officer, employee or Consultant of the Company or Subsidiary. (f)
      Each Option shall be confirmed by an Option agreement executed on behalf of the Company by any one director of the Board and by the Participant and each

      The exercise price of each Common Share purchased under an Option shall be paid in full in cash or by bank draft or certified cheque at the time of such exercise, in lawful money of Canada, and upon receipt of payment in full, but subject to the terms of the Plan, the number of Common Shares in respect of which the Option is exercised shall be duly issued as fully paid and non- assessable.(h)
      Subject to the terms and conditions of this Plan, an Option may be exercised by written notice signed by the Participant and dated the date of exercise, and not post-dated, stating that the Participant elects to exercise his rights to purchase Common Shares under such Option and the number of Common Shares in respect of which such Option is being exercised, accompanied by full payment for the Common Shares being purchased under such Option delivered to the Company at its principal office at Suite 900 - 409 Granville Street, Vancouver, BC, V6C 1T2 (or such other address of the principal office of the Company at the time of exercise) addressed to the attention of the President of the Company.

      the person is, or the Participant was, a director, officer, employee or Consultant of the Company or a director, officer, employee or Consultant of any Subsidiary or Associate and has not been induced to purchase the Common Shares by expectation of employment or continued employment;(b)
      the person is purchasing the Common Shares pursuant to the exercise of such Option as principal for the Participant’s own account (or if such Participant is deceased, for the account of the estate of such deceased Participant) for investment purposes, and not with a view to the distribution or resale thereof to the public;(c)
      the person will, prior to and upon any sale or disposition of any of the Common Shares purchased pursuant to the exercise of such Option, comply with all applicable securities laws and any other federal, provincial or state laws or

The Company may employ other procedures and require further documentation from a Participant to ensure compliance with all applicable laws.

The Company will be entitled to take such action as its deems necessary to restrict the transferability in the United States of any Common Shares acquired on exercise of any Option. 2.5
      Representation by the Company Each Option agreement related to stock option grants to an employee, Consultant or Management Company Employee shall include a representation by the Company that the Participant is a bona fide employee, Consultant or Management Company Employee of the Company or its Subsidiaries. 2.6
