1. Each of the Security Holders hereby places and deposits in escrow those
securities of the Issuer which are represented by the certificates described or
referred to in Schedule "A" (hereinafter, the "Escrowed Securities") hereto with
the Trustee and hereby undertakes and agrees forthwith to deliver those
securities (including any replacement securities or certificates if and when

and forming part of the Escrowed Securities are certain common shares of the
Issuer to be issued to certain of the Security Holders prior to closing of the
initial public offering of the Issuer pursuant to the Prospectus (as hereinafter
defined).

2. The parties hereby agree that the Escrowed Securities and the beneficial
ownership of or any interest in them and the certificate representing them
(including any replacement securities or certificates) shall not be sold,
assigned, hypothecated, alienated, released from escrow, transferred within
escrow, or otherwise in any manner dealt with, without the express consent,
order or direction in writing of the Ontario Securities Commission (hereinafter
referred to as the "Commission") being first had and obtained or except as may
be required by reason of the death or bankruptcy of any Security Holder, in
which cases the Trustee shall hold the said certificates subject to this
agreement, for whatever person, firm or corporation shall be legally entitled to
be or become the registered owner thereof.

3. The Security Holders hereby direct the Trustee to retain their respective
Escrowed Securities and the certificates (including any replacement securities
or certificates) representing the same and not to do or cause anything to be
done to release the same from escrow or to allow any transfer, hypothecation or
alienation thereof except with and as directed by the written

<PAGE>
                                      -3-


consent, order or direction of the Commission. The Trustee hereby accepts the
responsibilities placed on it hereby and agrees to perform the same in
accordance with the terms hereof and the written consents, orders or directions
of the Commission.

4. (a) The Trustee shall release from escrow the Escrowed Securities held by the
Trustee in the following amounts and at the following times, pro rata to the
Security Holders:

            (i)   10% of the Escrowed Securities immediately after that date
                  which is nine months following the date of the final receipt
                  of the Director under the Securities Act (Ontario) (the
                  "Director") for the prospectus dated March 5, 1996 of the
                  Issuer relating to the offering of common shares in the
                  capital of the Issuer (the "Prospectus");

            (ii)  a further 20% of the Escrowed Securities immediately after
                  each of the first, second and third anniversaries of the
                  release contemplated in clause 4(a)(i) above; and

            (iii) the remaining 30% of the Escrowed Securities immediately after
                  the fourth anniversary of the release contemplated in clause
                  4(a)(i) above.

      (b) Notwithstanding the provisions of paragraph 4(a), any Security Holder
may, at any time while any of the Escrowed Securities remain with the Trustee
pursuant to this agreement, apply to the Commission in accordance with the
policies of the Commission for the Commission's consent to the release from
escrow of all or part of the Escrowed Securities and the Trustee shall, upon
receipt of the written direction of such Security Holder and the consent of the
Commission, release such securities.

      (c) Notwithstanding the provisions of paragraph 4(a), upon the death of
any Security Holder who is an individual, that individual's Escrowed Securities
may be released from escrow by the Trustee such that 1/3 of such Escrowed
Securities have been released after the date of death, 2/3 of such Escrowed
Securities have been released after the first anniversary of the date of death
and all such Escrowed Securities have been released after the second anniversary
of the date of death, provided that the Trustee receives from the legal
representative of the deceased

<PAGE>
                                      -4-


Security Holder proper evidence that the Commission has been informed by notice
in writing of the date of death of such Security Holder.

      (d) This agreement has been made in connection with a proposed
distribution by the Issuer of common shares in respect of which the Issuer has
filed and obtained a receipt from the Commission for the preliminary prospectus
dated January 15, 1996. If a final receipt is not obtained from the Commission
for the Prospectus, or if subscriptions for the minimum offering of common
shares are not received by the agents by May 4, 1996:

            (i)   the Trustee shall forthwith after May 4, 1996 release all of
                  the Escrowed Securities from the provisions of this agreement;
                  and

            (ii)  this agreement shall cease, on May 4, 1996, to be of any
                  further force and effect.

5. The Security Holders, or any of them, may pledge, charge, hypothecate or
otherwise encumber their respective Escrowed Securities in order to secure their
bona fide indebtedness to a third party lender with whom the relevant Security
Holder deals at arm's length, if such lender acknowledges in writing, addressed
to the parties hereto and to the Commission, that the securities are held by,
and shall be dealt with by the Trustee, subject to and in accordance with this
agreement, and such acknowledgement is filed with the Commission.

6. If during the period in which any of the said Escrowed Securities are
retained in escrow pursuant hereto, any dividend is received by the Trustee in
respect of the Escrowed Securities, any such dividend shall be forthwith paid or
transferred to the respective Security Holders entitled thereto.

7. All voting rights attached to the Escrowed Securities shall at all times be
exercised by the respective registered owners thereof.

8. The Issuer and each Security Holder hereby agree to indemnify and hold
harmless the Trustee from and against any liability, loss, claim, action, cost,
and expense, including legal fees and disbursements, (collectively, the
"Liabilities") which may be asserted against the Trustee arising from or out of
this Agreement; provided that the Issuer and each Security Holder

<PAGE>
                                      -5-


shall not be required to indemnify the Trustee in the event that such
Liabilities are a result of the gross negligence or wilful misconduct of the
Trustee. This provision shall survive the resignation or removal of the Trustee
or the termination of this Agreement.

9. The Trustee shall be protected in acting and relying reasonably upon any
written notice, direction, instruction, order, certificate, confirmation,
request, waiver, consent, receipt, statutory declaration or other paper or
document (collectively referred to as "Documents") furnished to it and signed by
any person required to or entitled to execute and deliver to the Trustee any
such Documents in connection with this Agreement, not only as to its due
execution and the validity and effectiveness of its provisions, but also as to
the truth and accuracy of any information therein contained, which it in good
faith believes to be genuine.

10. The Trustee may retain legal counsel and advisors as may be reasonably
required for the purpose of discharging its duties or determining its rights
under this Agreement, and may rely and act upon the advice of such counsel or
advisor.

11. In consideration of the Trustee fulfilling its obligations hereunder, the
Issuer agrees to pay the Trustee such reasonable fees and expenses as the Issuer
and the Trustee may agree upon from time to time.

12. The Trustee shall have no duties or responsibilities except as expressly
provided in this Agreement and shall have no liability or responsibility arising
under any other agreement, including any agreement referred to in this
Agreement, to which the Trustee is not a party.

13. The Issuer hereby acknowledges the terms and conditions of this agreement
and agrees to take all reasonable steps to facilitate its performance.

14. If the Trustee should wish to resign, it shall give at least six months'
notice to the Issuer, which may, with the written consent of the Commission, by
writing appoint another Trustee in its place and such appointment shall be
binding on the Security Holders and the new Trustee shall assume and be bound by
the obligations of the Trustee hereunder.

15. The written consent, order or direction of the Commission as to a release
from escrow of all or part of the said Escrowed Securities shall terminate this
agreement only in

<PAGE>
                                      -6-


respect to those securities so released. For greater certainty this clause does
not apply to Escrowed Securities transferred within escrow.

16. Each Security Holder covenants and agrees that their respective, current
mailing address is set out in the register of the securities kept by the Trustee
as transfer agent and registrar and that, from time to time, they shall provide
to the Trustee their respective current mailing address.

17. This agreement may be executed in several parts in the same form and such
parts as so executed shall together form one original agreement, and such parts
if more than one shall be read together and construed as if all the signing
parties hereto had executed one copy of this agreement.

18. Wherever the singular or masculine are used throughout this agreement, the
same shall be construed as being the plural or feminine or neuter where the
context so requires.

19. This agreement shall enure to the benefit of and be binding upon the parties
hereto, their and each of their heirs, executors, administrators, successors and
assigns.
