                            PURPOSE AND PARTICIPATION

2.1      PURPOSE

The purpose of the Plan is to provide the Company with a share-related mechanism
to attract, retain and motivate qualified Directors, Employees,  Consultants and
Management  Company  Employees,  to reward such of those  Directors,  Employees,

goals of the  Company and to enable and  encourage  such  Directors,  Employees,
Consultants  and  Management  Company  Employees to acquire  Shares as long term
investments.

2.2      PARTICIPATION

The Board shall,  from time to time and in its sole discretion,  determine those
Directors and  Employees,  if any, to whom Options are to be awarded.  The Board
may, in its sole  discretion,  grant the  majority of the Options to insiders of
the  Company.  However,  in no case will an Option  Holder be  granted an Option

of the Company must not exceed 2% of the Company's issued and outstanding  share
capital as of the Award Date of the Option being granted, unless the TSX Venture

awarded.

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  the right to serve
or continue to serve as a Director nor does it give any Option Holder that is an
Employee,  Consultant  or  Managmeent  Company  Employee  the  right to be or to
continue  to be  employed  or engaged by the  Company or any  subsidiary  of the
Company.

2.6      REPRESENTATIONS OF THE COMPANY

As a condition  precedent to the issuance of an Option, the Company must be able
to  represent  as of the  Award  Date  that the  Option  Holder  is a bona  fide

a subsidiaryof the Company.

purchase  pursuant to Options granted  pursuant to this Plan will be that number
of Shares which is 10% of the issued and outstanding  shares of the Company from
time to time.  All stock options of the Company  outstanding as of the Effective
Date shall be deemed to be Options  outstanding  under this Plan.  If any Option
expires or otherwise  terminates for any reason without having been exercised in
full,  the  number of Shares in respect of which  Option  expired or  terminated
shall again be available for the purposes of granting  Options  pursuant to this
Plan.

3.3      TERM OF OPTION

Subject to  paragraph  3.4,  the Expiry  Date of an Option  shall be the date so
fixed by the Board at the time the particular  Option is awarded,  provided that
such date shall be no later than the fifth anniversary of the Award Date of such
Option.

Subject  to such  other  terms or  conditions  that may be  attached  to Options
granted  hereunder,  an Option Holder may exercise an Option in whole or in part

                           jurisdiction  to so order;  in which  case the Expiry
                           Date shall be the date the Option Holder ceases to be
                           a Director.

         (c)      Ceasing to be Employed

                  In the event that the Option Holder holds his or her Option as
                  an Employee,  Consultant  or Management  Company  Employee and
                  such Option  Holder  ceases to be an Employee,  Consultant  or
