                         SPECIFIC ASSIGNMENT OF LEASES

                                                       Dated: December 23, 1999

TO:   ROYAL TRUST CORPORATION OF CANADA
                      (the "Mortgagee")

WHEREAS:

A.    MARCO INVESTMENTS (ALBERTA) LTD. (the "Mortgagor") is the legal and
      beneficial owner of that certain parcel of land and premises (the "Lands")
      situate in Alberta and described as follows:

      PLAN CALGARY 4453L
      BLOCK SIX (6)
      LOTS TWELVE (12) AND THIRTEEN (13) AND THE EAST HALF OF LOT FOURTEEN (14)
      EXCEPTING AS TO SURFACE ONLY THE CORNER CUTS ON PLAN 6984 JK

B.    The Mortgagor is granting to the Mortgagee a mortgage (the "Mortgage") of
      the Lands of even date herewith and to be registered against the title to
      the Lands to secure, inter alia, payment of the principal sum of
      $314,806.00 together with interest thereon and all other monies due
      thereunder (the "Loan");

C.    The Mortgagor (or a prior registered owner of the Lands) has entered into
      leases (the "Leases") with respect to the Lands or parts thereof as more
      particularly set forth on Schedule "A" hereto;

D.    The Mortgagee will not advance the Loan unless these presents are
      executed;

NOW THEREFORE in consideration of the premises and of the sum of $1.00 now paid
by the Mortgagee to the Mortgagor and other good and valuable consideration, the
receipt and sufficiency of which the Mortgagor hereby acknowledges, the
Mortgagor hereby covenants and agrees that:

1.    The Mortgagor hereby assigns, transfers and sets over to the Mortgagee the
      Leases and the rents and other payments due or accruing due thereunder,
      and all other benefit and advantage to be derived therefrom, including the
      full benefit of all covenants and provisions contained in the Leases, the
      benefit of all guarantees of payment with respect thereto, the power to
      amend, modify, extend, cancel or terminate any Lease or accept any
      surrender thereof and the power to waive any default by a tenant
      thereunder.

2.    The Mortgagor represents and warrants that:


<PAGE>   5

                                       2


      (a)   each of the Leases is a good, valid and subsisting lease;

      (b)   the Leases have not been amended, modified or extended except as set
      forth in Schedule "A" and as disclosed to the Mortgagee;

      (c)   neither the Mortgagor nor any of the tenants under the Leases are
      presently in default of any of their obligations thereunder, nor do any of
      them presently have any dispute with any party thereto;

      (d)   the rent payable under each of the Leases has not been demanded,
      collected, accepted or paid in advance of the time for payment thereof or
      otherwise than in the manner set forth in such Lease;

      (e)   neither the Leases nor the rents payable thereunder are currently
      subject to any assignment, pledge, hypothecation or other encumbering by
      the Mortgagor (or any prior registered owner of the Lands), and the
      Mortgagor is absolutely and solely entitled to such rents; and

      (f)   there are no existing or future rights of set-off, assignment,
      commutation or prepayment with respect to the rents payable under any of
      the Leases.

3.    The Mortgagor covenants and agrees as follows:

      (a)   to at all times observe and perform all its obligations under the
      Leases, and to promptly provide to the Mortgagee on request a true copy of
      each Lease;

      (b)   not to amend, modify, extend, cancel or terminate any Lease or
      accept any surrender thereof except with the prior written consent of the
      Mortgagee;

      (c)   not to demand, collect or accept any rent payable under any of the
      Leases more than one month in advance of the time for payment thereof
      (except to the extent provided for under the Leases), except with prior
      written consent of the Mortgagee; and

      (d)   not to further assign, pledge, hypothecate or otherwise encumber the
      Leases or the rents payable thereunder.

4.    This assignment shall continue as security until the Loan is fully
      prepaid. The giving of this assignment is by way of additional and
      collateral security for the Loan and not in substitution for or in
      satisfaction of the Mortgage or of any other collateral security and will
      not in any way derogate from or delay or prejudice any rights or remedies
      to which the Mortgagee may be entitled under the Mortgage or under any
      other security collateral thereto or at law or at equity, and will not in
      any way prejudice or limit the Mortgagor's obligations under the Mortgage
      or under any such other security. Default

                                       3

      by the Mortgagor under any of the provisions hereof shall constitute a
      default under the Mortgage.

5.    Neither this assignment nor anything contained herein shall bind the
      Mortgagee to recognize any or all of the Leases nor in any way render the
      interest of the Mortgagee under the Mortgage subject to any of the Leases.
      The Mortgagor hereby indemnifies the Mortgagee against and will hold the
      Mortgagee harmless from any and all liability, loss or damage which the
      Mortgagee may suffer or incur under any of the Leases and of and from any
      and all claims and demands whatsoever which may be asserted against the
      Mortgagee by reason of any alleged obligation or undertaking on its part
      to perform or discharge any of the terms of any of the Leases and any such
      liability, loss or damage together with interest thereon at the rate
      prescribed in the Mortgage shall be secured hereby and by the Mortgage and
      shall be payable upon demand.

6.    The Mortgagor hereby grants to the Mortgagee full power and authority,
      with or without entry upon the Lands, to enforce the covenants and
      provisions set forth in the Leases, including the power and authority to
      demand, collect, sue for, distrain for, recover, receive and give receipts
      for the rents under the Leases, in the Mortgagee's own name or in the name
      of and as agent for the Mortgagor, as the Mortgagee may elect, and the
      Mortgagor hereby grants to the Mortgagee irrevocable authority to join the
      Mortgagor in any such proceedings or actions, whether judicial or
      extra-judicial.

7.    The parties agree that this Assignment is an actual assignment effective
      as of the date hereof and that the Mortgagee may at its option, serve on
      each of the tenants under the Leases a notice with regard to this
      assignment and the disposition of future rents under the Leases. For the
      consideration aforesaid and in further consideration of the Mortgagee
      directing the tenants to continue to pay to the Mortgagor the rentals and
      other monies due under the Leases on but not prior to accrual until
      further notices are received from the Mortgagee (which notices, at the
      Mortgagee's discretion, are to be provided upon a default on the part of
      the Mortgagor occurring under these presents or under the Mortgage or
      under any of the Mortgagor's obligations to the Mortgagee under any other
      security for the Loan), the Mortgagor hereby covenants and agrees with the
      Mortgagee that upon the Mortgagee in its unfettered discretion being of
      the opinion that a default as aforesaid has occurred and thereafter
      serving on the tenants notices in writing requiring such tenants to
      thereafter pay the rents and other monies due under the Leases to the
      Mortgagee, the Mortgagor shall cause payment to the Mortgagee of the said
      rentals and other monies, and none of such tenants (or guarantors or
      indemnifiers) shall be obliged to inquire as to the Mortgagee's right
      thereto, and the Mortgagor hereby acknowledges that any and all payments
      which may be effected by, or on behalf of, a tenant pursuant to any such
      notices, shall to the extent of any such payment, operate as a discharge
      of each such tenant of and in respect of rent or other monies due and
      payable under such Lease. Upon demand made by the Mortgagee on the tenant
      under any of the Leases or on any person otherwise liable for any of the
      rents thereunder, such tenant or person shall, and is


<PAGE>   7

                                       4

      hereby authorized and directed to pay to or upon the Mortgagee's order,
      and without any inquiry of any nature, all rents then or thereafter
      accruing under the Leases, and such demand shall be sufficient authority
      for the said tenant or person to pay such rents to the Mortgagee, without
      reference to whether such demand is made in accordance with this
      agreement.

8.    Nothing herein set forth will be deemed to make the Mortgagee responsible
      for the collection of the rents or for the observance or performance of
      any of the provisions of the Leases either by the Mortgagor or by any
      holders of the Leases, or to render the Mortgagee a mortgagee in
      possession of the Lands or in any way accountable or liable as such, or to
      impose any obligation on the Mortgagee to take any action or to exercise
      any remedy on the collection or recovery of the rents or to sell to or
      enforce the performance of the obligations and liabilities of any person
      under or in respect of all or any of the Leases.

9.    The Mortgagee will be liable to account to the Mortgagor for only such
      monies as it actually receives in its hands pursuant to this assignment,
      after deduction of any collection charges, inspection fees, costs as
      between solicitor and his own client, and other expenses to which the
      Mortgagee may be put in respect thereof, and the balance of such monies,
      when so received by the Mortgagee will be applied on account of the Loan.

10.   In the event that a proposal or a notice of intention to file a proposal
      is filed under the Bankruptcy and Insolvency Act (Canada) by a tenant
      under a Lease, and such tenant thereby seeks to repudiate that Lease:

      (a)   all benefits which might otherwise accrue to the Mortgagor as
      landlord including, without limitation, all monies required to be paid as
      aforesaid, shall be paid to the Mortgagee, all of which such benefits and
      monies being hereby assigned to the Mortgagee. All monies so received by
      the Mortgagee shall, at the Mortgagee's option, either be paid to the
      Mortgagor in whole or in part (the amounts to be determined at the
      absolute discretion of the Mortgagee) or be applied on account of the
      Loan; and

      (b)   all notices which may be given to the Mortgagor as landlord, shall
      also be given to the Mortgagee, and all right of the Mortgagor as landlord
      to respond (including the making of any objection or the taking of any
      other step) with respect to the tenant's proposal or repudiation of the
      Lease shall be vested in the Mortgagee who shall have the right (but not
      the obligation), as agent and in the name of the Mortgagor or otherwise,
      to respond in such manner as to the Mortgagee may seem fit. It is
      understood and agreed that if the Mortgagee responds as aforesaid, the
      Mortgagee shall be entitled to prefer its own interests (as mortgagee)
      over that of the Mortgagor, and the Mortgagor agrees to and does hereby
      indemnify the Mortgagee against all costs, proceedings, claims and demands
      which may be made against the Mortgagee in or as a result of the Mortgagee
      responding as aforesaid.

11.   (a)   The Mortgagor will execute such further assurances as the Mortgagee
      may reasonably require from time to time to perfect this assignment.

      (b)   Time will be of the essence hereof.

      (c)   This assignment will be governed by the laws of the Province of
      Alberta.

      (d)   Where the context so requires all references herein to the singular
      will be construed to include the plural, the masculine to include the
      feminine and neuter genders and, where necessary, a body corporate, and
      vice versa; and in any case where this assignment is executed by more than
      one party, all provisions hereof shall be construed and taken as against
      such executing parties as joint and several.

      (e)   This assignment will enure to the benefit of and be binding upon the
      Mortgagor and the Mortgagee and their respective heirs, executors,
      administrators, successors and assigns.

IN WITNESS WHEREOF this assignment has been executed under seal as of the date
first written above.
