each parties hereto) the Corporation and the Optionee hereby agree as follows:

the exercise price of fifteen cents US ($0.15 US funds) per Optioned Share and

<PAGE>

3.        The Purchaser shall, subject to the terms and conditions hereinafter
set out, have the right to exercise the Three Hundred Thousand (300,000) options
hereby granted with respect to all or any part of the optioned shares at any
time or from time to time after the hold period date hereof and prior to close
of business on July 31, 2006 (Hereinafter called the "Expiry Date"). On the
Expiry Date the options hereby granted shall forthwith expire and terminate and
be of no further force or effect whatsoever as to such of the Optioned Shares in
respect of which the options hereby granted have not been exercised. The
Optioned Shares are subject to a four-month hold period from the effective date.

4.        In the event of the death of the Purchaser on or prior to the Expiry
Dates while a director of the Corporation, the option hereby granted to the
Purchaser may be exercised, as to such of the Optioned Shares in respect of
which option has not previously been exercised as the Purchaser would have then
been entitled to purchase, by the legal personal representatives of the
Purchaser at any time up to and including (but not after) a date of six (6)
months following the date of death of the Purchaser or to the close of business
on the expiry date, whichever is earlier.

5.        In the event of the resignation or discharge of the Purchaser as a
director of the Corporation prior to the Expiry Dates, the option hereby granted
to the Purchaser shall after ninety (90) days following the Purchaser ceasing to
be a director of the Corporation, cease and terminate and be of no further force
or effect whatsoever as to such of the Optioned Shares in respect of which such
option has not been previously exercised.

6.        If at any time when the option hereby granted remains unexercised with
respect to any Optioned Shares, (a) a general offer to purchase all of the
issued shares of the Corporation made by a third party or (b) the Corporation
proposes to sell all or substantially all of its assets and undertaking or to
merge, amalgamate or be absorbed by or into any other company (save and except
for a subsidiary or subsidiaries of the Corporation) under any circumstances
which involve or may involve or require the liquidation of the Corporation, a
distribution of its assets among its shareholders, or the termination of its
corporation existence, the Corporation shall use its best efforts to bring such
offer or proposal to the attention of the Purchaser as soon as practicable and
(I) the options hereby granted may be exercised, as to all or any of the
Optioned Shares in respect of which such options have not been previously
exercised, by the Purchaser at any time up to and including (but not after) a
date ninety (90 days following of the completion of such sale or prior to the
close of business on the Expiry Dates, whichever is the earlier; and (ii) the
Corporation may, at its option, require the acceleration of the time for the
exercise of the said option and of the time for the fulfilment of any conditions
or restrictions on such exercise.

7.        Subject to the provisions of paragraph 4, 5 and 6 hereof, the options
hereby granted shall be exercisable (at any time and from time to time as
aforesaid) by the Purchaser or his legal personal representative giving a notice
in writing addressed to the Corporation at its principal office in the City of
Toronto, Ontario and delivered to the Secretary of the Corporation, which notice
shall

                                      -3-

specify the number of optioned shares in respect of which such notice is being
exercised and shall be accompanied by payment (by cash or certified cheque) in
full of the purchase price for such number of optioned shares so specified
therein. Upon any such exercise of options as aforesaid the Corporation shall
forthwith cause the transfer agent and registrar of the Corporation to deliver
to the Purchaser or his legal personal representatives (or as the Purchaser may
otherwise direct in the notice of exercise of option) within ten (10) days
following receipt by the Corporation of any such notice of exercise of option a
certificate or certificates in the name of the Purchaser or his legal personal
representatives representing in the aggregate such number of optioned shares as
the Purchaser or his legal personal representatives shall have then paid.

8.        Nothing herein contained or done pursuant hereto shall obligate the
Purchaser to purchase and/or pay for any Optioned Shares except those Optioned
Shares in respect of which the Purchaser shall have exercised his options
hereunder in the manner hereinbefore provided.

9.        In the event of any sub-division, re-division or change of the shares
of the Corporation at any time prior to the expiry date into greater number of
shares, the Corporation shall deliver at the time of any exercise thereafter of
the option hereby granted such additional number of shares as would have
resulted from such sub-division or change if such exercise of the option hereby
granted had been prior to the date of sub-division re-division or change.

          In the event of any consolidation or change of the shares of the
Corporation at any time prior to the Expiry Dates into a lesser number of
shares, the number of shares deliverable by the Corporation on any exercise
thereafter of the option hereby granted shall be reduced to such number of
shares as would have resulted from such consolidation or change if such exercise
of the option hereby granted had been prior to the date of such consolidation or
change.

10.       The Purchaser 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) other than in respect of the
Optioned Shares in respect of which the Purchaser shall have exercised his
option hereunder and which the Purchaser shall have actually taken up and paid
for.

11.       Time shall be of the essence of this Agreement.

12.       This Agreement shall enure to the benefit of and be binding upon the
Corporation, its successors and assigns, and the Purchaser and his legal
personal representative to the extent provided in paragraph 4 hereof.  This
Agreement shall not be assignable by the Purchaser or his respective legal
representative.

13.       This Agreement shall be construed in accordance with and be governed
by the laws of the Province of Ontario and shall be deemed to have been made in
said Province.
