unless the context  otherwise  requires,  the following  words and phrases shall
have the following ascribed to them below:

     a. "Cash Flow" means net income derived from the business of the Issuer, as
shown on the audited  financial  statements  or  verified by Issuer's  auditors,
adjusted for the following add backs:

i.       depreciation,
ii.      depletion,
iii      deferred taxes,
iv.      amortization of goodwill, and
v.       amortization of research and development costs.

     b. "Related Party" means promoters,  officers, directors, other insiders of
the Issuer and any associates or affiliates of the foregoing.

     2. Each of the Security  Holders  hereby places and deposits in escrow with
the Trustee those of his  securities in the Issuer which are  represented by the
certificates  described  in  Schedule  "X" and the Trustee  hereby  acknowledges
receipt of those  certificates.  The Security Holders agree to deposit in escrow
any further  certificates  representing  securities  in the Issuer  which he may
receive as a stock dividend on securities hereby escrowed, and to deliver to the
Trustee  immediately on receipt  thereof the  certificates  for any such further
securities and any replacement  certificates which may at any time be issued for
any escrowed securities.

     3. The Parties hereby agree that,  subject to the provisions of paragraph 6
herein,  the 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 written consent of The Alberta Stock Exchange  (hereinafter referred
to as the  "Exchange")  given to the  Trustee  or except as may be  required  by
reason of the death or  bankruptcy  of any  Security  Holder,  in which case the
Trustee shall hold the said certificates subject to this agreement, for whatever
person,  or company  shall be legally  entitled to become the  registered  owner
thereof


     4. The  Security  Holders  direct the  Trustee to retain  their  respective
securities  and  the  certificates  (including  any  replacement  securities  or
certificates)  representing  them and not to do or cause  anything to be done to
release them from escrow or to allow any transfer,  hypothecation  or alienation
thereof,  without the written  consent of the Exchange.  The Trustee accepts the
responsibilities  placed on it by this  agreement  and agrees to perform them in
accordance with the terms of this Agreement and the written  consent,  orders or
directions of the Exchange.

     5. Any  Security  Holder  may apply to the  Exchange  for a  consent  for a
transfer within escrow and shall,  before  applying,  give reasonable  notice in
writing of its intention to the Issuer and the Trustee.

     6. (a) The  Exchange  will  consent to the release from escrow of one share
for each $0.20 of Cash Flow.

     (b) Any release from escrow under this  paragraph 6 shall be made  pursuant
to a written application of behalf of the Issuer or the Security Holders,  which
application shall be accompanied by evidence of the Cash Flow received in a form
satisfactory to the Exchange.  Application for release may only be made once per
year and may only relate to Cash Flow received in the  preceding  fiscal year or
the fiscal years of the Issuer  since the last  release from escrow  pursuant to
this  agreement,  whichever is greater.  All shares  released from escrow shall,
unless  otherwise  directed  by the  Exchange,  be  distributed  pro-rata to all
Security Holders.

     (c) Notwithstanding subparagraph (b) above, the maximum number of shares to
be released from escrow in any year to a Security  Holder who is a Related Party
shall be one-third of the original  number of shares held in escrow on behalf of
such Security Holder.

     7. A release  from escrow of all or part of the escrowed  securities  shall
terminate this agreement  only in respect to those  securities so released.  For
greater certainty this paragraph does not apply to securities transferred within
escrow.



     8. The Security Holders shall, if a dividend is declared while the escrowed
securities  or any of them  continue to be held in escrow under this  Agreement,
renounce and release any right to receive  payment of the dividend on the shares
then held in escrow.

     9. If the Issuer is wound up and any securities remain in escrow under this
agreement at the time when a distribution  of assets to holders of securities is
made by the liquidator, the Security Holders shall assign their right to receive
that part of the distribution  which is attributable to the escrowed  securities
to the Trustee,  for the benefit of, and in trust for the persons and  companies
who are then holders of free  securities in the Issuer rateably in proportion to
their holdings.

     10. a. In the  event  that any or all of the  business  of the  Issuer  has
become of little value or no value,  the Issuer shall declare the  occurrence of
that event,  with full particulars  thereof,  to the Exchange by a resolution of
its directors  and those  Security  Holders who are directors  from time to time
hereby  agree to  cause  such  resolution  to be  passed  and  certified  to the
satisfaction of the Exchange;

     b. The Security  Holder jointly and severally agree with the Issuer and the
     Trustee that in the event of such diminution of value,  the securities held
     in escrow shall not be cancelled  or released  from escrow,  in whole or in
     part, except with the consent of the Exchange.

     c. The Exchange may, in its sole discretion,  having regard to the value of
     the  business  of the  Issuer  as  ultimately  established  and such  other
     circumstances  as  it  may  consider  relevant,  determine  the  number  of
     securities to be cancelled or released and shall  communicate  its decision
     in writing to the Trustee.  If the Exchange  determines  that less than all
     the securities  then held in escrow shall be cancelled or released shall be
     taken rateably from the escrowed  security  holding of each of the Security
     Holders,  unless the Exchange  otherwise  directs or the Security  Holders,
     with the consent of the Exchange, otherwise agree in writing.

     d. On receipt  by the  Trustee of a  determination  to cancel,  each of the
     Security Holders shall tender the required number of escrowed securities to
     the Issuer by way of gift for cancellation  and, the Issuer shall thereupon
     take the necessary action, by way of reduction of capital or otherwise,  to
     cancel them, and the  certificates  for these securities shall be delivered
     up for cancellation.




     e. Each of the Security Holders  undertakes and agrees to vote and cause to
     be voted their respective securities in a manner consistent with the terms,
     conditions  and  intent of this  agreement  in  relation  to the  aforesaid
     gifting back of securities for cancellation.

     11. Notwithstanding  paragraphs 6 and 10, any shares remaining in escrow on
the fifth anniversary of the date of this agreement,  unless otherwise  exempted
in writing by the Exchange, shall be cancelled by the Trustee within 6 months of
the said fifth anniversary.

     12. All voting  rights  attached to the  escrowed  securities  shall at all
times be exercised by the respective registered owners thereof.

     13. The Security  Holders and the Issuer hereby jointly and severally agree
to and do hereby  release and  indemnify  and save harmless the Trustee from and
against all claims,  suits,  demands,  costs,  damages and expenses which may be
occasioned  by reason of the  Trustee's  compliance in good faith with the terms
hereof.

     14.  The  Issuer  hereby  acknowledges  the  terms and  conditions  of this
Agreement and agrees to take all reasonable  steps to facilitate its performance
and to pay the  Trustee's  proper  charges  for its  services as trustee of this
escrow.

     15.If the Trustee  should wish to resign,  it shall give at least 3 months'
notice to the Issuer which may,  with the written  consent of the  Exchange,  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.

     16. The covenants of the Security Holders with the Issuer in this agreement
are made with Issuer  both in its own right and as trustee for the holders  from
time to time of free  securities in the Issuer,  and may be enforced not only by
the Issuer but also by any holder of free securities.

     17. This  agreement  may be executed in several  parts of the same form and
the parts as so executed shall together constitute one original  agreement,  and
the 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 is used, the same shall be construed
to include the plural or feminine or neuter where the context so requires.

     19.  This  agreement  shall  ensure to the benefit of and be binding on the
parties to this  agreement and each of their heirs,  executors,  administrators,
successors and assigns.




     IN WITNESS  WHEREOF the Issuer and Trustee  have  caused  their  respective
corporate  seals to be hereto  affixed and the Security  Holders have hereto set
their respective hands and seals.
