      owned by one of them) but concurrently is or becomes one or more other
      type of Optionee, the Option will not terminate but will continue in full
      force and effect and the Optionee may exercise the Option until the
      earlier of (a) the Expiry Date and (b) the applicable date set forth in
      subparagraphs (a), (b) or (c) above where the Optionee ceases to be any
      type of Optionee.

1.8 Subject to the provisions of this Agreement and the Plan
and subject to compliance with any applicable securities laws, the Options shall
be exercisable, in full or in part, at any time after vesting, until
termination; provided, however, that if the Optionee is subject to the reporting
and liability provisions of Section 16 of the Securities Exchange Act of
1934 with respect to the Common Stock, the Optionee shall be precluded from
selling, transferring or otherwise disposing of any Common Stock underlying any
Options during the six (6) months immediately following the grant of that
Option. If less than all of the shares included in the vested portion of any
Options are purchased, the remainder may be purchased at any subsequent time
prior to the Expiry Date. Only whole shares may be issued pursuant to the
exercise of any Options, and to the extent that any Options covers less than one
(1) share, it is unexercisable.

Each exercise of the Options shall be by means of delivery of a
Notice of Exercise (which may be in the form attached hereto as Appendix A) to
the President of the Company at its principal executive office, 

4

specifying the number of shares of Common Stock to be purchased
and accompanied by payment in cash by certified check or cashier's check in the
amount of the full exercise price for the Common Stock to be purchased. In
addition to payment in cash by certified check or cashier's check, an Optionee
or transferee of the Options may pay for all or any portion of the aggregate
exercise price by complying with one or more of the following alternatives:

	 	(a) 	
      by delivering a properly executed Notice of Exercise
      together with irrevocable instructions to a broker promptly to sell or
      margin a sufficient portion of the Common Stock and deliver directly to
      the Company the amount of sale or margin loan proceeds to pay the exercise
      price; or

	 	 	 
	 	(b) 	
      by complying with any other payment mechanism approved by
      the Board at the time of exercise.

It is a condition precedent to the issuance of Optioned Shares
that the Optionee execute and/or deliver to the Company all documents and
withholding taxes required in accordance with applicable laws.

1.9 Nothing in this Agreement shall obligate the Optionee to
purchase any Optioned Shares except those Optioned Shares in respect of which
the Optionee shall have exercised the Options in the manner provided in this
Agreement.

1.10 Reference is made to the Plan for particulars of the
rights and obligations of the Optionee and the Company in respect of:

	 	(a) 	
      the terms and conditions on which the Options are
      granted; and

	 	 	 
	 	(b) 	
      a consolidation or subdivision of the Company's share
      capital or an amalgamation or merger;

all to the same effect as if the provisions of the Plan were
set out in this Agreement and to all of which the Optionee assents.

1.11 The terms of the Options are subject to the provisions of
the Plan, as the same may from time to time be amended, and any inconsistencies
between this Agreement and the Plan, as the same may be from time to time
amended, shall be governed by the provisions of the Plan.

      Optionee in writing), substantially in the form attached as Appendix "A"
      hereto, which notice shall specify therein the number of Optioned Shares

Expiry Date, expire and be of no further force or effect whatsoever.

1.5 The Company shall not be obligated to cause the issuance,
transfer or delivery of a certificate or certificates representing Optioned
Shares to the Optionee, until provision has been made by 

3

the Optionee, to the satisfaction of the Company, for the
payment of the aggregate exercise price for all Optioned Shares for which the
Option shall have been exercised, and for satisfaction of any tax withholding
obligations associated with such exercise.

1.6 The Optionee shall have no rights whatsoever as a
shareholder in respect of any of the Optioned Shares (including any right to
receive dividends or other distribution therefrom or thereon) except in respect
of which the Option has been properly exercised in accordance with the terms of
this Agreement.

1.7 The Option will terminate under the following
circumstances:

	 	(a) 	
      If the Optionee is an employee, consultant, director or
      officer of the Company or a subsidiary of the Company, and ceases to be an
      employee, consultant, director or officer by reason of termination or
      removal for cause, the Option will terminate on the effective date of the
      Optionee ceasing to be an employee, consultant, director or officer, as
      the case may be, for that reason.

	 	 	
       

	 	(b) 	
      If the Optionee dies, the Optionee’s personal
      representative will have the right to exercise any unexercised portion of
      the Option, in whole or in part, at any time until the earlier of (a) the
      Expiry Date and (b) the date that is three months after the date of the
      Optionee’s death.

	 	 	
       

	 	(c) 	
      If the Optionee is a director, officer, employee or
      consultant of the Company or a subsidiary of the Company, and ceases to be
      a director, officer, employee or consultant for any reason other than as
      set out in subparagraphs (a) or (b) above, the Option will terminate on
      the earlier of (a) the Expiry Date and (b) the date that is 30 days after
      the effective date of the Optionee ceasing to be a director, officer,
      employee or consultant for that other reason.

	 	 	
       

	 	(d) 	
      If the Optionee ceases to be one type of Optionee (i.e.,
      director, officer, employee or consultant, or a company 100% beneficially
      owned by one of them) but concurrently is or becomes one or more other
      type of Optionee, the Option will not terminate but will continue in full
      force and effect and the Optionee may exercise the Option until the
      earlier of (a) the Expiry Date and (b) the applicable date set forth in
      subparagraphs (a), (b) or (c) above where the Optionee ceases to be any
      type of Optionee.

	 	 	
       

	 	(e) 	
      The Option will not be affected by any change of the
      Optionee’s employment where the Optionee continues to be employed by the
      Company or any subsidiary of the Company.

1.8 Subject to the provisions of this Agreement and the Plan
and subject to compliance with any applicable securities laws, the Options shall
be exercisable, in full or in part, at any time after vesting, until
termination; provided, however, that if the Optionee is subject to the reporting
and liability provisions of Section 16 of the Securities Exchange Act of
1934 with respect to the Common Stock, the Optionee shall be precluded from
selling, transferring or otherwise disposing of any Common Stock underlying any
Options during the six (6) months immediately following the grant of that
Option. If less than all of the shares included in the vested portion of any
Options are purchased, the remainder may be purchased at any subsequent time
prior to the Expiry Date. Only whole shares may be issued pursuant to the
exercise of any Options, and to the extent that any Options covers less than one
(1) share, it is unexercisable.

4

Each exercise of the Options shall be by means of delivery of a
Notice of Exercise (which may be in the form attached hereto as Appendix A) to
the President of the Company at its principal executive office, specifying the
number of shares of Common Stock to be purchased and accompanied by payment in
cash by certified check or cashier's check in the amount of the full exercise
price for the Common Stock to be purchased. In addition to payment in cash by
certified check or cashier's check, an Optionee or transferee of the Options may
pay for all or any portion of the aggregate exercise price by complying with one
or more of the following alternatives:

	 	(a) 	
      by delivering a properly executed Notice of Exercise
      together with irrevocable instructions to a broker promptly to sell or
      margin a sufficient portion of the Common Stock and deliver directly to
      the Company the amount of sale or margin loan proceeds to pay the exercise
      price; or

	 	 	 
	 	(b) 	
      by complying with any other payment mechanism approved by
      the Board at the time of exercise.

It is a condition precedent to the issuance of Optioned Shares
that the Optionee execute and/or deliver to the Company all documents and
withholding taxes required in accordance with applicable laws.

1.9 Nothing in this Agreement shall obligate the Optionee to
purchase any Optioned Shares except those Optioned Shares in respect of which
the Optionee shall have exercised the Options in the manner provided in this
Agreement.

1.10 Reference is made to the Plan for particulars of the
rights and obligations of the Optionee and the Company in respect of:

	 	(a) 	
      the terms and conditions on which the Options are
      granted; and

	 	 	 
	 	(b) 	
      a consolidation or subdivision of the Company's share
      capital or an amalgamation or merger;

all to the same effect as if the provisions of the Plan were
set out in this Agreement and to all of which the Optionee assents.

1.11 The terms of the Options are subject to the provisions of
the Plan, as the same may from time to time be amended, and any inconsistencies
between this Agreement and the Plan, as the same may be from time to time
amended, shall be governed by the provisions of the Plan.
