              Purpose

            

    

    

    The
purpose of the Plan is to provide the Company with a share-related mechanism to
attract, retain and motivate qualified Directors, Officers, Consultants and
Employees, to reward such of those Directors, Officers, Consultants and
Employees as may be awarded Options under the Plan by the Board from time to
time for their contributions toward the long term goals of the Company and to
enable and encourage such Directors, Officers, Consultants and Employees to
acquire Common Shares as long term investments.

    

    
      	
              2.2

            	
              Participation

            

    

    

    The Board
shall, from time to time and in its sole discretion, determine which of the
Eligible Persons, if any, shall be awarded Options. The Board shall only award
an Option to a Consultant or an Employee if the Consultant or Employee is a bona
fide Consultant or Employee of the Company or an affiliate of the Company, and
the Board shall make such a representation if required by the Regulatory
Authorities. The Board may, in its sole discretion, grant the majority of the
Options to insiders of the Company.

              Notification of
      Award

            

    

    

    Following
the award of an Option by the Board, the Administrator shall notify the Option
Holder in writing of the award and shall enclose with such notice the Option
Certificate representing the Option so awarded.

    

    
      	
              2.4

            	
              Copy of
      Plan

            

    

    

    Each
Option Holder, concurrently with the notice of the award of the Option, shall be
provided with a copy of the Plan. A copy of any amendment to the Plan shall be
promptly provided by the Administrator to each Option Holder.

    

    
      	
              2.5

            	
              Limitation

            

    

    

    The Plan
does not give any Option Holder that is a Director or Officer the right to serve
or continue to serve as a Director or Officer of the Company or any of its
affiliates nor does it give any Option Holder that is an Employee or Consultant
the right to be or to continue to be employed with or have a consulting contract
with the Company or any of its affiliates.

              Termination

            

    

    

    Subject
to subparagraphs (a) to (e) below and subject to paragraph 3.7, the Expiry Date
of an Option shall be the date fixed by the Board at the time the particular
Option is awarded (the “Fixed Expiry Date”) provided that the Expiry Date shall
be no later than the tenth anniversary of the Award Date of such
Option:

    

    
      	 	
              (a)

            	
              Death

            

    

    

    If the
Option Holder dies while his or her Option is outstanding, then unless otherwise
provided for in the Option Certificate, the following shall apply. The Expiry
Date for any vested portion or portions of the Option shall be the earlier of
the Fixed Expiry Date and the date that is six months after the date of the
Option Holder’s death. The Expiry Date for any unvested portion of the Option

              Ceasing to be a
      Director

            

    

    

    If the
Option Holder holds an Option as a Director and the Option Holder ceases to be a
Director (other than by reason of death), then unless otherwise provided for in
the Option Certificate, the following shall apply. The Expiry Date for any
vested portion or portions of the Option shall be the earlier of the Fixed
Expiry Date and the 90th day following the date that the Option Holder ceases to
be a Director unless the Option Holder ceases to be a Director for Cause, in
which case the Expiry Date shall be the date that the Option Holder ceases to be
a Director. The Expiry Date for any unvested portion of the Option shall be the
date that the Option Holder ceases to be a Director. The right to purchase
Common Shares under an Option shall not vest after the date that the Option
Holder ceases to be a Director.

    

    
      	 	
              (c)

            	
              Ceasing to be an

an Officer (other than by reason of death), then unless otherwise provided for
in the Option Certificate, the following
shall apply. The Expiry Date for any vested portion or portions of the Option
shall be the earlier of the Fixed Expiry Date and the 90th day following the
date that the Option Holder ceases to be an Officer unless the Option Holder

              Change of
      Control

            

    

     

    In the
event of a Change of Control or impending Change of Control, the Board may, in
its sole discretion, deal with outstanding Options in the manner it deems fair
and reasonable in light of the circumstances. Without limiting the generality of
the foregoing, the Board may, without any action or consent required on the part
of any Option Holder:

    

    
      
        	 	
                (i)

              	
                subject
      to TSX approval, deliver a notice to the Option Holder advising the Option
      Holder that the unvested portion of the Option held by the Option Holder,
      if any, shall immediately
vest;

              

      

    

     

    
      
        	 	
                (ii)

              	
                deliver
      a notice to an Option Holder advising the Option Holder that the Expiry
      Date for any vested portion or portions of the Option shall be the earlier
      of the Fixed Expiry Date and the 10th
      day following the date of the notice and the Expiry Date for any unvested
      portion of the Option shall be the date of the notice;
      or

              

      

    

     

    
      
        	 	
                (iii)

              	
                take
      such other actions, and combinations of the foregoing actions, as it deems
      fair and reasonable under the
circumstances.

              

      

    

    

    The
foregoing subparagraphs (b) through (d) shall only apply once an Option Holder
ceases to fall into any of the categories of Eligible Persons. The Board and the
Administrator shall look to which of the definitions of Employee, Director,
Officer or Consultant the Option Holder met immediately prior to the Option
Holder ceasing to be an Eligible Person to determine which of subparagraphs (b)
through (d) shall apply. If the Option Holder met more than one definition, then
the following shall apply. If the Option Holder was an Employee or Consultant,
then the Option Holder shall be deemed to hold his or her Option as an Employee
or Consultant regardless of whether the Option Holder was also a Director or
Officer. If the Option Holder was a Director but not an Employee or Consultant,
then the Option Holder shall be deemed to hold his or her Option as a Director
regardless of whether the Option Holder was also an Officer.

at which an Option Holder may purchase a Common Share upon the exercise of an
Option shall be as set forth in the Option Certificate issued in respect of such
Option and in any event shall not be less than the Market Price of the Common
Shares as of the Award Date. Notwithstanding anything else contained herein, in
no case shall the Exercise Price be less than the minimum prescribed by the
organized trading facilities as would apply to the Award Date in
question.

                Subject
      to all applicable Securities Laws and the rules and policies of all
      applicable Regulatory Authorities, the Board may attach other terms and
      conditions to the award of a particular Option, such terms and conditions
      to be referred to in a schedule attached to the Option Certificate. These
      terms and conditions may include, but are not necessarily limited to,
      providing that an Option or a portion or portions of an Option expire on a
      certain date, after certain periods of time or upon the occurrence of
      certain events other than as provided for herein, provided that no Option
      shall expire more than ten years after the Award
  Date.

      the Company has received Disinterested Shareholder Approval to do so, the
      aggregate number of Common Shares number of common shares (i) issued to
      Insiders within any twelve month period and (ii) issuable to Insiders at
      any time, under the Plan or when combined with all of the Company’s other
      security-based compensation arrangements, cannot exceed 10% of issued and
      outstanding Common Shares.

Black-Out Period then, notwithstanding any other provision of this Plan, the
Option shall expire 10 business days after the Black-Out Period is lifted by the
Company.

    

    "Black-Out
Period" means that period during which a trading black-out is imposed by the
Company to restrict trades in the Company’s securities.

      Common Shares) or rights, options or warrants to acquire Common Shares or
      securities convertible into or exchangeable for Common Shares or other

    then,
subject to any required action by the shareholders of the Company and any
necessary approval of the Regulatory Authorities, any term that the Board
determines requires adjustment (including the number of Common Shares subject to
each outstanding Option and the number of Common Shares that have been
authorized for issuance under the Plan but as to which no Options have yet been
granted or that have again become available for the purposes
of the Plan, the Exercise Price of each outstanding Option, as well as any other
terms that the Board determines require adjustment) shall be adjusted by the
Board in an appropriate and proportionate manner, and its determination shall be
final, binding and conclusive. Except as the Board determines, no issuance by
the Company of Shares of any class, or securities convertible into Shares of any
class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or Exercise Price of Common Shares subject to an Option.
No fractional shares shall be issued upon the exercise of an Option and
accordingly, if as a result of the adjustment, an Option Holder would become
entitled to a fractional Common Share, such Option Holder shall have the right
to purchase only the next lowest whole number of Common Shares and no payment or
other adjustment shall be made with respect to the fractional interest so
disregarded.

    An Option
may be exercised only by the Option Holder or the Personal Representative of the
Option Holder. An Option Holder or the Personal Representative of the Option
Holder may exercise the vested portion or portions of an Option in whole or in
part at any time or from time to time during the Exercise Period up to 5:00 p.m.
local time in Vancouver, British Columbia on the Expiry Date by delivering to
the Administrator an Exercise Notice, the applicable Option Certificate and a

shall cause to be delivered to the Option Holder a certificate for the Common
Shares purchased by the Option Holder. If the number of Common Shares in respect
of which the Option was exercised is less than the number of Common Shares
subject to the Option Certificate surrendered, the Administrator shall forward a
