   2
                                  INSTRUCTIONS

1. IF YOU ARE UNABLE TO ATTEND THE MEETING, BUT WISH TO BE REPRESENTED, YOU HAVE
   THE RIGHT TO APPOINT A PERSON, WHO NEED NOT BE A SHAREHOLDER OF THE
   CORPORATION TO ATTEND AND VOTE ON YOUR BEHALF. IF YOU USE THIS FORM OF PROXY,
   BUT WISH TO APPOINT SOME PERSON OTHER THAN MR. DENNIS WOOD OR MR. CLAUDE
   MICHAUD AS YOUR PROXYHOLDER, YOU MUST STRIKE OUT THEIR NAMES AND INSERT THE
   NAME OF THAT OTHER PERSON IN THE BLANK SPACE PROVIDED. THE PROXYHOLDER MUST
   ATTEND THE MEETING IN ORDER TO VOTE ON YOUR BEHALF.

2. You should indicate your choice on the matter set out above by checking the
   appropriate box. IF NO CHOICE IS SPECIFIED YOUR COMMON SHARES WILL BE VOTED
   IN FAVOUR OF THE APPROVAL OF THE ARRANGEMENT RESOLUTION AND IN ACCORDANCE
   WITH MANAGEMENT'S RECOMMENDATION WITH RESPECT TO AMENDMENTS OR VARIATIONS OF
   THE MATTERS SET OUT IN THE NOTICE OF THE MEETING OR ANY OTHER MATTERS WHICH
   MAY PROPERLY COME BEFORE THE MEETING.

3. THE SHARES REPRESENTED BY THIS FORM OF PROXY WILL BE VOTED ON ANY BALLOT THAT
   MAY BE CALLED FOR IN ACCORDANCE WITH THE INSTRUCTIONS CONTAINED HEREIN. IN
   THE ABSENCE OF SUCH INSTRUCTIONS, SUCH SHARES WILL BE VOTED IN FAVOUR OF THE
   APPROVAL OF THE ARRANGEMENT RESOLUTION AND IN ACCORDANCE WITH MANAGEMENT'S
   RECOMMENDATION WITH RESPECT TO AMENDMENTS OR VARIATIONS OF THE MATTERS SET
   OUT IN THE NOTICE OF THE MEETING OR ANY OTHER MATTERS WHICH MAY PROPERLY COME
   BEFORE THE MEETING.

4. Please sign exactly as your common shares are registered. If the shareholder
   is a corporation, this proxy must be executed by a duly authorized officer or
   attorney of the shareholder and, if the corporation has a corporate seal, its
   corporate seal should be affixed. If shares are registered in the name of an
   executor, administrator or trustee, please sign exactly as the shares are
   registered. If the shares are registered in the name of a deceased
   shareholder, the shareholder's name must be printed in the space provided,
   the proxy must be signed by the legal representative with his name printed
   below his signature and evidence of authority to sign on behalf of the
   shareholder must be attached to this proxy.

5. Registered holders of shares are entitled to dissent from the Arrangement
   Resolution in accordance with the dissent procedures (the "Dissent
   Procedures") set out in the section entitled "Dissenting Shareholder Rights"
   in the accompanying Circular and as set out in the section entitled "Rights
   of Dissent" in the plan of arrangement attached as Annex C to the Circular.
   THE DISSENT PROCEDURES REQUIRE THAT A REGISTERED HOLDER OF COMMON SHARES OF
   THE CORPORATION WHO WISHES TO DISSENT MUST PROVIDE TO THE CORPORATION A
   DISSENT NOTICE PRIOR TO 5:00 P.M. ON THE BUSINESS DAY PRECEDING THE MEETING.
   IT IS IMPORTANT THAT SHAREHOLDERS STRICTLY COMPLY WITH THIS REQUIREMENT, AS
   IT IS DIFFERENT FROM THE STATUTORY DISSENT PROVISIONS OF THE CANADA BUSINESS
   CORPORATIONS ACT WHICH WOULD PERMIT A DISSENT NOTICE TO BE PROVIDED AT OR
   PRIOR TO THE MEETING. A shareholder may only exercise the right to dissent in
   respect of common shares which are registered in that shareholder's name. In
   many cases, shares beneficially owned by a holder (a "non-registered holder")
   are registered in the name of a securities dealer or broker or other
   intermediary, or a clearing agency. Shareholders, including non-registered
   holders, who wish to dissent should carefully review the Dissent Procedures.
   The failure to comply strictly with the Dissent Procedures may result in the
   loss or unavailability of the right to dissent.

6. All shareholders should refer to the accompanying Circular for further
   information regarding completion and use of this proxy and other information
   pertaining to the Meeting. All capitalized terms used herein and not
   otherwise defined herein have the meanings ascribed to them in the Circular.

7. To be valid, this proxy must be dated and signed by you, as the registered
   holder of common shares of the Corporation, or as a person named as a
   proxyholder in respect of the Meeting in an omnibus proxy containing a power
   of substitution pursuant to applicable securities laws, or your attorney.


                      THIS IS YOUR PROXY. PLEASE COMPLETE,
                    FOLD AND RETURN IN THE ENVELOPE PROVIDED.
