GROSS RENT

The Sub-Tenant shall pay to the Sub-Landlord in and for each year of the
Sub-Lease, Gross Rent of two hundred and nineteen thousand, seven hundred and
eighty Dollars ($219,780.00) per annum being a rate of $15.00 per square foot
per annum, plus Goods and Services Taxes and any other Sales Taxes (hereinafter
defined) of the rentable area set out in paragraph 1 above; payable by equal
monthly installments of $18,315.00 plus Goods and Services Taxes in advance on
the first day of each month of the term.  The above amounts are subject to
increase by reason of the Realty Tax Adjustment.

"Realty Tax Adjustment"  means the amount of increase for Realty and Business
taxes (collectively "Realty Taxes") relating to the Leased Premises as charged
to the Sub-Landlord from the Head Landlord in excess of the estimated per square
foot 1998 annual rate of $3.77.  Such amounts in excess thereof are due to
Sub-Landlord should the Realty Taxes during the Term exceed this rate.  Any
amount paid to Head Landlord by Sub-Landlord in excess of the $3.77 rate will be
due to Sub-Landlord, when Sub-Landlord pays such amount(s) to Head Landlord.

"Sales Taxes" means all goods and services taxes, sales taxes, value added
taxes, business transfer taxes, and any other taxes imposed on the Sub-Landlord
with respect to rent or any other charges payable by the Sub-Tenant to the

Sub-Landlord all Sales Taxes.  The Sub-Tenant will reimburse the Sub-Landlord
for all Sales Taxes at the full rate applicable from time to time, without
reference to any tax credits available to the Sub-Landlord.  The amount of Sales
Taxes payable by the Sub-Tenant will be calculated by the Sub-Landlord in
accordance with the applicable legislation and will be paid to the Sub-Landlord
at the same time as the amounts in respect of which it is required to be paid
are paid.  The amounts payable by the Sub-Tenant as Sales Taxes will be deemed
not to be rent, but the Sub-Landlord has all of the same rights in respect of
Sales Taxes as it has in respect of rent under this Sub-Lease.

Nothing in this Sub-Lease will suspend or delay the payment of any rent at the
time it is due and payable.  The Sub-Tenant waives any rights it may have
(whether granted by applicable landlord and tenant legislation, and amendments
thereto, or otherwise) to claim any setoff of all or part of any debt of the
Sub-Landlord to the Sub-Tenant against rent.  The Sub-Landlord may, at its
option, apply sums received against any amounts payable under this Sub-Lease in
any manner the Sub-Landlord chooses.

"Interest Rate"  means the rate of interest equal to five (5) percent above
prime, being the prime rate of interest charged by The Bank of Nova Scotia at
the time of any rent being in arrears, and any such rent in arrears will bear
interest at the Interest Rate.

All amounts payable by the Sub-Tenant under this Sub-Lease are deemed to be
rent, except as otherwise expressly provided in this Sub-Lease.  Every reference
in this Sub-Lease to "rent" is a reference to rent, and all other amounts
payable by the Sub-Tenant under this Sub-Lease, except


                                           
<PAGE>

pursuant to Section.

increase under the Realty Taxes Adjustment.  Notwithstanding the foregoing, the
Sub-Tenant shall be entitled to occupy the Leased Premises from the date of
execution of the Sub-Lease by both parties until July 31, 1998 on a rent free
basis, provided all other terms of this Sub-Lease are otherwise followed.

the Head Lease.

options granted by the Head Landlord to the Sub-Landlord under the Head Lease.
