                  thereof in question the Tenant shall pay the deficiency to the
                  Landlord within ten (10) days after notice from the Landlord
                  of the amount of the deficiency. Similarly, if the total of
                  the monthly installments paid by the Tenant is more than the
                  actual amount of the Tenant's proportionate share of the
                  Operating Costs applicable for the calendar year or portion
                  thereof in question, the Landlord shall pay to the Tenant the
                  amount of the excess within ten (10) days after its notice
                  setting out actual amount of the Tenant's proportionate share
                  of the Operating Cost if applicable, or alternatively grant a
                  credit to the Tenant's account against current and future
                  Operating Costs.

         (d)      The Tenant's Proportionate Share shall be the fraction which
                  has as its numerator the area of the Premises and has as its
                  denominator the total area of all buildings which comprise the
                  development of which the premises form part. Area of the
                  Buildings which comprise the development shall mean from time
                  to time the aggregate of the areas of all leasable premises
                  measured in the same way as contemplated by Section 4.8 of
                  this Lease.

         (e)      In the case of premises in the two storey building known as
                  2321 Fairview Street, the Landlord may make a separate
                  assessment of Additional Operating Costs for which the Tenants
                  Proportionate Share shall be a fraction which has as its
                  numerator the area of the demised premises and has as its
                  denominator the Area of the Building.

                  own expense wish to make changes, including, without

                  Landlord may impose conditions upon such construction as it
                  considers necessary to protect the building or to ensure the
                  orderly completion of the work.

         (b)      The Tenant, at its own expense, shall have the right, subject
                  to the approval of the Landlord and in accordance with all
                  local by-laws, to install signs designating its company name
                  on the Premises.

10.4     REPAIR WHERE THE TENANT IS AT FAULT

         If the building or any part of it requires repair, replacement or

regulations require any changes in the Premises, the Tenant shall perform such
changes at its own expense, but subject to the provisions of Section 10.3.

10.6     LANDLORD'S ALTERATIONS

         The Landlord may from time to time alter or change the improvements or
permit such to be altered or changed, in the Building or on the Land by the

including, without limitation, the construction of other rentable premises. In
the course of conducting any such improvements, the Landlord shall have the
right to make alterations, structural or otherwise, to the Premises including,
without limitation, the running of ducts or conduits through the Premises, but

ARTICLE XI - DAMAGE, DESTRUCTION & EXPROPRIATION

11.1     TERMINATION IN THE EVENT OF DAMAGE AND DESTRUCTION

         (a)      If the Building is damaged and/or destroyed so that it will
                  require more than 120 days to repair the same, the Landlord
                  may, by written notice to the Tenant within 30 days of the
                  date of such damage, terminate this Lease effective on the
                  date of such damage and destruction.

         (b)      Upon any damage or destruction to the Premises, provided that
                  the Landlord has not terminated this Lease, the Landlord and
                  the Tenant shall repair the Premises in accordance with their
                  obligations to repair under Sections 10.1 and 10.2 of this
                  Lease as soon as reasonably possible and during the period
                  following the occurrence of such destruction or damage, for so
                  long as the Landlord is fully reimbursed from proceeds payable
                  under policies of insurance maintained by the Landlord,
                  minimum rent and additional rent shall from time to time abate
                  in the same proportion that the part of the Premises from time
                  to time rendered unfit for use or occupancy by reason of such
                  destruction is of the whole of the Premises.

writing, surrender this lease and all the remainder of the term, if any, then
yet to come and unexpired, as from the day mentioned in such notice, and will,
subject nevertheless to the provisions hereinbefore contained thereupon, vacate
the premises and yield up to the Landlord the peaceable possession thereof.

It is understood that the said six month's notice need not expire at the end of
any year or at the end of any month and in the event of the day fixed for
termination of the lease expiring on some other day than the last day of a
month, the rent for such month shall be apportioned for the broken period. The
Tenant's responsibility for payment of rent and additional rent shall be limited
to the period of time during occupancy which may be less than six months if the
Lessee vacates prior to the expiration of the six months notice period.

ARTICLE XII - INSURANCE & LIABILITY

12.1     TENANT'S INSURANCE

         The Tenant shall throughout the Term provide and keep in force:

         (a)      comprehensive general liability insurance in the name of the
                  Landlord and the Tenant with respect to the business carried
                  on in or from the Premises and the use and occupancy thereof
                  by the Tenant for bodily injury and death and damage to
                  property of others; and

         (b)      fire insurance on an "all risks" basis in respect of the
                  Improvements and the Tenant's fixtures, furniture, equipment
                  and inventory.

Insurance effected by the Tenant under this Section 12.1 shall be in amounts
which the Landlord acting reasonably shall from time to time determine as being
sufficient, and shall name the Landlord as an additional name-insured and in
respect of the insurance described in Subsection 12.1(a) provide for a
cross-liability endorsement. Such insurance shall release the Landlord from
certain liability as set out in Section 12.4 and shall otherwise be upon such
terms and conditions as the Landlord acting reasonably shall from time to time
require as being reasonable and sufficient. The Tenant shall upon request file
with the Landlord copies of current certificates, to establish the Tenant's
insurance coverage in effect from time to time and the payment of premiums
thereon.


12.2     LANDLORD'S INSURANCE

         The Landlord will maintain at the expense of the Tenant, throughout the
Term, in those reasonable amounts, and with those reasonable deductions that a
prudent owner of a building similar to the Building would maintain, having
regard to size, age and location, (a) all risks insurance on the Building
(excluding the foundations and excavations) and the machinery, boilers and
equipment contained in it and owned by the Landlord, (except property that the
Tenant and other Tenants are required to insure); (b) public liability and
property damage insurance with respect to the Landlord's operations in the
Building.

12.3     INDEMNITY BY THE TENANT

         The Tenant shall indemnify and hold harmless the Landlord against any
and all liability, loss, claims, demands, damages or expenses, including legal
expense, due to or arising out of injury to any person (including injury
resulting in death) and damage to, loss of or theft of any property of any
person arising out of any accident or other occurrence on or about the Premises
or any act or neglect
<PAGE>   13

                                      -10-

by the Tenant or those over whom it might be expected to exercise control, and
costs, liabilities, damages or expenses due to or arising out of any work done
by, or act of neglect or emission of the Tenant or its servants, employees,
agents, contractors, invitees, concessionaires or licensees in and about the
Premises, or due to or arising out of any breach or non-performance by the
Tenant of any provision of this Lease.

12.4     LIMITATIONS OF LANDLORD'S LIABILITY

         The Landlord shall not be liable or in any way responsible to the
Tenant in respect of any loss, injury or damage required to be insured against
by the Tenant under the provisions of Section 12.1, whether or not such loss,
injury or damage is the result of the negligence of the Landlord or those for
whom the Landlord is in law responsible. The Landlord shall not be liable for
its failure to perform any of its covenants hereunder provided that it is using
its commercially reasonable efforts to rectify' such default as soon as
reasonably possible.

12.5     LIMITATION OF TENANT'S LIABILITY

         The Tenant shall not be liable or in any way responsible to the
Landlord in respect of any loss, injury or damage to the extent that the
Landlord actually recovers proceeds under insurance policies maintained by the
Landlord pursuant to Section 12.2, whether or not such loss, injury or damage is
the result of the negligence of the Tenant or those for whom the Tenant is in
law responsible.

12.6     INCREASE IN INSURANCE PREMIUMS

         The Tenant will not do or omit or permit to be done or omitted, any
thing upon the Leased Premises which shall cause the rate of insurance upon the
Building, or any part thereof, to be increased, and if the insurance rate shall
be increased as aforesaid the Tenant will pay to the Landlord as additional
rent, in addition to any part of insurance premiums hereinbefore agreed to be
paid by the Tenant, the amount by which the insurance premiums shall be so
increased, and, if notice of cancellation shall be given respecting any
insurance policy, or, if any insurance policy upon the Building or any part
thereof shall be cancelled or its renewal be refused by an insurer by reason of
the use of the Premises by the Tenant, the Tenant shall alter, remedy or rectify
such use upon being requested to do so in writing by the Landlord, and if the
Tenant shall fail to do so within twenty-four (24) hours of such written
request, the Landlord may at its option terminate this Lease forthwith by
leaving upon the Leased Premised notice in writing of its intention so to do. In
determining whether increased premiums are the result of the Tenant's use of the
Premises, a schedule, issued by the organization ranking the insurance rate on
the Premises, showing the various components of such rate, shall be conclusive
evidence of the several items and charges which make the insurance rate on the
leased Premises. Any increase in insurance premiums payable to the Tenant as
aforesaid, shall be payable forthwith upon demand in writing therefore by the
Landlord.

12.7     UNAUTHORIZED USE OF CHEMICALS

         The Tenant hereby indemnifies and saves harmless the Landlord from all
liability, cost, claims and damages resulting from the unauthorized or negligent
use of any chemical or other substance which are not permitted to be used
according to any Federal, Provincial or Municipal regulations and in particular
in regards to any contaminant as that term is defined in The Environmental
Protection Act, furthermore, the Tenant shall on breach of the above covenant
conduct the necessary clean up of the premises and any other property
contaminated by the Tenant. Failure to do so shall entitle the Landlord to
conduct the cleanup and recover the cost as rent pursuant to the lease.

ARTICLE XIII - ASSIGNMENT OR SUBLETTING

13.1     ASSIGNMENT OR SUBLETTING BY THE TENANT

         The Tenant shall not assign this Lease or sublet all or any part of the
Leased Premises without the prior written consent of the Landlord which shall
not be unreasonably withheld. The Tenant shall be responsible for and shall pay
to the Landlord forthwith on demand all reasonable administrative and legal
costs of the Landlord in connection with the Landlord's consent to any
assignment of subletting by the Tenant. Any such assignment or subletting
consented to by the Landlord shall not

<PAGE>   14

                                     - 11 -

release the Tenant of any obligations of the Tenant under the provisions of this
Lease. It is a condition of such assignment or subletting that the assignee or
subtenant directly agree with the Landlord to be bound by the provisions of this
Lease and upon such assignment or subletting the Tenant shall forthwith furnish
copies of all documents relating thereto to the Landlord and the Tenant at the
request of the Landlord shall enforce for the benefit of the Landlord all
obligations of third parties contained in all or any of such documents to the
extent necessary to give effect to this Lease.

13.2     TRANSFERS AND ENCUMBRANCES BY THE LANDLORD

         The Landlord may sell, transfer, encumber or otherwise deal with the
Land and Building or any portion thereof or any interest of the Landlord
therein, in every case without the consent of the Tenant. To the extent that any
purchaser or transferee from the Landlord assumes responsibility for the
covenants of the Landlord under this Lease, the Landlord shall without further
written agreement be freed and relieved of liability upon such covenants and
obligations.

13.3     CHANGE OF CONTROL

         Any change in the effective voting control of a corporate tenant or
corporate guarantor (whether by sale, transfer or other disposition of shares or
otherwise and whether direct or indirect), without the consent of the Landlord,
shall entitle the Landlord, at its option, to terminate this Lease. The Tenant
shall make available to the Landlord all records reasonably required by the
Landlord to determine whether any such change of control has occurred.

13.4     SECURITY ON IMPROVEMENTS AND FIXTURES

         The Tenant shall not create any encumbrance or other security in any of
its property that is or becomes an improvement or trade fixture that had
priority above the Landlord's interest in such property.

ARTICLE XIV

14.1     SUBORDINATION AND ATTORNMENT BY THE TENANT

         This Lease is subject and subordinate to (but at the option of the
Landlord or any mortgagee or encumbrancer of the Land and Building shall be
attorned and the Tenant bound to) any mortgage or other encumbrance which may
now or at any time hereafter affect the Premises. On request at any time and
from time to time of the Landlord or of any such mortgagee or encumbrancer of
the Premises, the Tenant covenants and agrees to either (i) attorn to such
mortgagee or encumbrancer and become bound to it as its tenant of the Premises
for the then unexpired residue of the Term and upon the terms herein contained
(subject always to the respective priorities as between themselves or mortgagees
or encumbrancers who from time to time request such attornment) or (il) postpone
and subordinate this Lease to such mortgage or other encumbrance with the intent
and effect that this Lease and all the rights of the Tenant shall be subject to
the rights of such mortgagee or encumbrancer as fully as if such mortgage or
other encumbrance had been made before the making of this Lease. Whichever of
the foregoing may be requested (and notwithstanding that any previous attornment
and subordination shall have been given) the Tenant shall execute promptly any
instruments of attornment, postponement or subordination which may be so
requested to give effect to the foregoing. Whenever requested from time to time
by the Landlord or any mortgagee or encumbrancer of the Premises, the Tenant
shall promptly execute and deliver to the party requesting the same a
certificate or acknowledgement as to the status and validity of this Lease and
the state of the rental account hereunder and such other information as may be
reasonably required.

ARTICLE XV - DEFAULT

15.1     RE-ENTRY AND TERMINATION ON DEFAULT

                  If and whenever:

         (a)      any Basic Rent or additional rent payable by the Tenant under
                  this Lease shall be in arrears and shall not then be paid
                  within fifteen (15) days, or

         (b)      the Tenant shall have breached or failed to comply with any of
                  its covenants and agreements contained in this Lease, and
                  shall have failed to commence to remedy such breach of
                  non-compliance within fifteen (15) days after written notice
                  thereof given by the Landlord to the Tenant (or such longer
                  period if any as the Landlord may allow acting reasonably for
                  the remedying of such breach of non-compliance) or thereafter
                  fails to diligently proceed to remedy such breach or
                  non-compliance;

then and in every case it shall be lawful for the landlord at any time
thereafter at its option to enter into and upon the Premises or any part thereof
in the name of the whole and to terminate this Lease and all the rights of the
Tenant hereunder, anything in the Lease to the contrary notwithstanding.

15.2     RIGHT TO TERMINATE OR RELET

         If the Landlord does not exercise its right under Section 15.1 to
terminate this Lease, it may nevertheless relet the Premises or a part of them
for whatever term or terms (which may be for a term extending beyond the Term)
and at whatever rent and upon whatever other terms, covenants and conditions the
Landlord considers advisable and may at its option enforce subleases of the
Premises and collect rents thereunder to apply against the obligations of the
Tenant under this Lease, in which case the Tenant shall continue to be liable
for the performance of all of its obligations under this Lease including the
payment of rent and all amounts payable hereunder.

15.3     BANKRUPTCY OF THE TENANT AND ADDITIONAL RIGHTS OF TERMINATION

         In addition to all other rights of the Landlord to terminate hereunder,
whether or not the Term has commenced and whether or not any Basic Rent has been
prepaid, this Lease may be terminated at the option of the Landlord if the
Tenant shall make a general assignment for the benefit of its creditors, shall
be declared to be bankrupt, or shall file a petition in bankruptcy or insolvency
or for any re-adjustment of debts or creditor's arrangement or shall make a
proposal under the Bankruptcy Act or take advantage of any legislation for the
relief of bankrupt or insolvent debtors in respect of its own debts, or if any
execution, attachment or similar process shall be issued against the Tenant, or
any encumbrancer of the Tenant shall take any action or proceeding whereby any
of the improvements, fixtures, furnishings or property of the Tenant on the
Premises or the Tenant's leasehold interest in the Premises shall be taken, or
if the Tenant attempts to remove any substantial part of the fixtures,
furnishings or stock-in-trade from the premises other than in the normal course
of its business, or if a receiver, manager, custodian or any official having
similar power shall be appointed with respect to the Premises or any property of
the Tenant on the leased Premises. If this Lease is terminated pursuant to any
provisions of this Section 15.3, the Tenant shall, in addition to meeting all
the other requirements of this Article XV, forthwith pay to the Landlord Basic
Rent for the three (3) months next ensuing after the termination of this Lease
as accelerated rent.

15.4     LANDLORD'S RIGHTS TO CURE DEFAULTS

         If and whenever the Tenant shall default in the performance of any of
its covenants under this Lease including, without limitation, the Tenant's
obligation to repair and maintain the Premises and/or take out insurance, the
Landlord may perform such covenant for the account of the Tenant and may enter
upon the Premises for the purpose, and no notice thereof need be given to the
Tenant except if and to the extent any provision of this Lease expressly
required that notice be given in the circumstances. The Landlord shall not be
liable to the Tenant for any loss, damage or inconvenience to the Tenant or to
the Tenant's business or stock-in-trade caused by acts of the Landlord in
remedying or attempting to remedy such default, and the Tenant shall promptly
pay to the Landlord on demand the amount of all costs, charges and expenses
incurred by the Landlord in connection with
<PAGE>   16

                                     - 13 -

such default or in curing or attempting to cure such default, together with an
administrative fee of fifteen percent (15%) of such amount.

15.5     REMEDIES GENERALLY

         Mention in this Lease of any particular remedy or remedies of the
Landlord in respect of any default by the Tenant shall not preclude the Landlord
from any other remedy in respect thereof, whether available at law or in equity,
or by statute, or expressly provided for herein. No remedy shall be exclusive or
dependent upon any other remedy, but the Landlord may from time to time exercise
any one or more of such remedies generally or in combination, such remedies
being cumulative and not alternative.

15.6     WAIVER

         No waiver by the Landlord or the Tenant of any default, breach or
non-compliance hereunder shall operate as a waiver of such party's rights
hereunder in respect of any continuing or subsequent default, breach of
non-observance, and no waiver shall be inferred from or implied by any
overlooking by the Landlord or the Tenant of such default, breach or
non-observance.

15.7 LANDLORD'S ENTRY

         The Landlord may enter onto the Premises for the purpose of:

         (a)      showing the Premises to prospective tenants of the Premises or
                  purchasers or mortgagees of the Building;
