     (b)  If the Commencement Date is on a day other than the first day of a

          Commencement Date to the end of the month in which the Commencement

     (c)  The Tenant will deliver to the Landlord at the beginning of each
          Rental Year a series of monthly post-dated cheques for the Rental Year
          for the aggregate of the monthly payments of Minimum Rent and any
          payments of Additional Rent estimated by the Landlord in advance as
          well as any payments required by this Lease to be paid monthly in
          advance.

     (d)  The Landlord acknowledges receipt of the sum of THREE THOUSAND TWO
          HUNDRED FIVE DOLLARS ----78/00 ($3,205.78) which represents a security
          deposit equal to the last month of the Term, the balance for
          application by the Landlord against payment of Rent for the first
          month of the Term. The Landlord may apply all or part of the amount
          retained for a security deposit as compensation for any loss or damage
          arising from the breach by the Tenant of any provision of this Lease.
          This right will not be construed to limit the Landlord's other rights
          under this Lease or at a law or to limit the amount recoverable by the
          Landlord for damages in respect of other breaches by the Tenants of
          this Lease. If the Landlord uses all or part of the Security Deposit
          as provided above, the Tenant will, upon notification of the Landlord
          pay to the Landlord the amount required to reimburse it for the
          amounts so applied. The Landlord will not be required to pay interest
          to the Tenant on any of the amounts paid to the Landlord or retained
          by it under this paragraph. The Landlord will refund the Security
          Deposit within thirty (30)days of the expiry of the Lease upon
          satisfactory inspection of the Leased Premises.

     (e)  If construction of the Leased Premises or the Project is not completed
          by the Commencement Date or if on that date, a previous Tenant or
          occupant is overholding, and the Landlord is therefore unable to
          deliver vacant possession of the Leased Premises, the Landlord will
          exercise all its rights diligently in order to obtain completion of
          the construction and vacant possession, and the Rent payable under
          this Lease will abate until the Leased Premises are available for
          occupancy by the Tenant. The Landlord will not be liable to the Tenant
          for damages and this Lease will, subject to the abatement of Rent
          provided for in this paragraph, be in full force with no change to the
          Commencement Date or the Expiry Date.

     (f)  If the Tenant fails to pay when it is due, Minimum Rent, Additional
          Rent, or any other amount payable by it under this Lease, the unpaid
          amount will bear interest at the rate of four (4%) percent per month
          pro-rated from the due date to the date of payment and subject to
          annual compounding.

     5.04 and 6.02 of this Lease. However, the Landlord may defer payment of any
     such Taxes or defer compliance with any statute, law, by-law, if it
     diligently prosecutes any contest or appeal of those Taxes.

5.03 Taxes Payable by the Tenant

     The Tenant will pay as Additional Rent to the Landlord a share of the Taxes
     determined as follows:

     (a)  the Tenant will pay the amount determined when the appropriate mill

     (b)  the Tenant will also pay its Proportionate Share of any amounts
          determined by applying the appropriate mill rate for Taxes against any
          separate Assessments for the Common Areas and Facilities or any part
          of them, and

     (c)  if there is not or if there ceases to be a separate Assessment for the
          Leased Premises or if there ceases to be a separate Assessment for any
          part of the Common Areas and Facilities for which there was one
          previously during the Term, the Landlord will determine what the
          separate Assessments would have been, having regard, to the extent
          possible, to the assessment principles and methods properly employed
          by the assessment authority having jurisdiction and the Landlord's
          determination will be considered to be that separate Assessment.

5.04 Business Taxes and Other Taxes of Tenant

     In addition to the Taxes payable by the Tenant under Section 5.03, the
     Tenant will pay as Additional Rent to the proper taxing authorities or to
     the Landlord, as it might direct, and will discharge in each Rental Year

     Leased Premises or the Landlord on account of its ownership of them or its
     interest in them, and (ii) every tax and license fee which is levied,
     rated, charged, or assessed against or in respect of the business carried
     on in the Leased Premises or in respect of the use or occupancy of the
     Leased Premises by the Tenant, and every occupant of the Leased Premises,
     or against the Landlord on account of its ownership of or interest in the

     fees are rated, charged or assessed by any federal, provincial, municipal,
     school or other body during the Term. If there are not separate bills
     provided for Business Taxes, the Tenant will pay its Proportionate Share of
     the Business Taxes or Taxes in the nature of Business Taxes levied, rated,
     charged or assessed on the Project.

     Landlord considers advisable and the Tenant will diligently prosecute the
     appeal or contestation to a speedy resolution and will keep the Landlord
     informed of its progress from time to time. If the Tenant fails to five
     notice to the Landlord required in this subparagraph, then, without
     limiting the Landlord's other remedies, the Tenant will be responsible
     during the Term, for payment to the Landlord, the difference between the
     Taxes and Business Taxes which would have been payable as the result of the
     appeal or contestation not been made and the Taxes and Business Taxes
     payable as a result of the appeal or contestation, (e) the Tenant will
     indemnify the Landlord against all loss, cost, charges and expenses
     occasioned by or arising from all Taxes in respect of the Leased Premises
     and all Business Taxes and any taxes which may in future be levied in lieu
     of Taxes or Business Taxes or which may be assessed against any rentals
     payable under this Lease in Lieu of Taxes or Business Taxes, whether
     against the Landlord or the Tenant including but not limited to any
     increase occurring in Taxes or Business Taxes arising directly or
     indirectly out of any appeal or contestation of the Tenant of the Taxes or
     Business Taxes relating to the Leased Premises or the Project or any part
     of them. The Tenant will promptly deliver to the Landlord whatever security
     for any increase in Taxes and Business Taxes which the Landlord considers
     advisable.

6.03 Estimated Costs

     (a)  The amounts payable by the Tenant under Section 5.03 and Article VI
          may be estimated by the Landlord for whatever period the Landlord
          determines from time to time, and the Tenant will pay to the Landlord
          the Tenant's share or the Tenant's Proportionate Share, as the case
          may be, as so estimated, of the amounts in monthly instalments in
          advance during that period as Additional Rent. If the Landlord revises
          an estimated amount the Tenant will, within five (5) days of being
          notified, provide to the Landlord a series of post-dated cheques for
          the remaining months of the Rental Year in substitution of the
          post-dated cheques which the Tenant was previously required to provide
          to the Landlord and the Landlord will, upon receiving the substitute
          cheques, return to the Tenant those which the Landlord previously
          held. As soon as bills for all or any part of those estimated amounts
          are received, the Landlord may bill the Tenant for the Tenant's share
          or Proportionate Share as the case may be, and the Tenant will pay the
          Landlord the amounts so billed, (less the amounts previously paid by
          the Tenant on the basis of the Landlord's estimate as provided above)
          as Additional Rent on demand.

     (b)  Within a reasonable period after the end of the period for which the
          estimated payments have been made, the Landlord will deliver to the
          Tenant, (i) a statement of the amounts and costs referred to in
          Section 5.03 together with a statement of the Tenant's share of such
          amounts and costs, and (ii) a statement of the costs and expenses
          referred to in Article VI together with a statement of the Tenant's
          Proportionate Share of those costs and expenses, and if necessary an
          adjustment will be made between the parties in accordance with
          subparagraph (c) below.

     (c)  If the Tenant has paid in excess of the amounts due the excess will be
          refunded by the Landlord within a reasonable period after the deliver
          of the statement or, at the Landlord's option, credited against the
          next payment of Minimum Rent and Additional Rent payable by the
          Tenant. If the amount the Tenant has paid is less that the amounts
          due, the Tenant will pay the additional amounts with the next monthly
          payment of Minimum Rent. If any Rental Year is greater or less than
          the period determined by the Landlord as provided above, the Tenant's
          Proportionated Share will be adjusted on a per diem pro rata basis.

IT IS UNDERSTOOD THAT DURING THE INITIAL TERM OF THE LEASE ONLY, AND PROVIDING
THE TENANT IS IN POSSESSION OF THE LEASED PREMISES, THE TENANT'S SHARE OF
OPERATING COSTS, DUE UNDER ARTICLE 6.01 AND 6.02 SHALL BE INCLUDED IN RENTAL DUE

               the Landlord and subject to adjustment by the Landlord within a
               reasonable time after the end of the period in respect of which
               the estimate has been made;

     Premises, and if the Tenant fails to remedy the condition giving rise to
     the cancellation, threatened cancellation or reduction of coverage within

     condition giving rise to the cancellation, threatened cancellation or
     reduction of coverage, and the Tenant will immediately pay the costs and

          the business carried on by the Tenant, to perform the maintenance and
          repairs or replacements because of laws or other requirements of
          governmental authorities having jurisdiction or because of the act,
          omission, neglect or default of the Tenant, or those for whom the
          Tenant is in law responsible, the Tenant will pay for the total cost
          of the maintenance, repairs or replacements together with a sum equal
          to fifteen (15%) percent of the total costs representing the
          Landlord's overhead and the payment will be due and payable as
          Additional Rent on demand.

11.04 Repair on Notice

     In addition to the Tenant's obligations under Section 11.01, the Tenant
     will effect the maintenance and Work referred to in that Section in
     accordance with notice from the Landlord but failure to give the notice
     does not relieve the Tenant from its obligations under Section 11.01.

11.05 Surrender of the Leased Premises

     On the expiry or earlier termination of the Term, the Tenant will peaceably
     surrender the Leased Premises to the Landlord in first class condition;
     will deliver all the keys for the Leased Premises to the Landlord at the
     place then fixed for the payment of rent and will inform the Landlord of
     all combinations of locks, safes and vaults, if any in the Leased Premises.
     The Tenant will also remove its trade fixtures, any alterations or
     improvements which the Landlord requests it to remove before surrendering
     the Leased Premises, and will immediately repair any damage to the Leased
     Premises caused in the removal. This obligation survives the expiration of
     the Term or earlier termination of this Lease.

11.06 Repair where Tenant at Fault

     Despite anything else in this Lease, including but not limited to Section
     11.03, Section 10.05 and Section 6.02 (b), if the Project or any part of it
     or the Common Areas and Facilities or any part of them, require repair or
     replacement because of the acts of the Tenant (negligent or otherwise) the
     costs together with the sum equal to fifteen (15%) percent of that cost
     representing the Landlord's overhead will be paid by the Tenant to the
     Landlord as Additional Rent on demand.

     The Tenant will not install any equipment which overloads the capacity of
     any utility, electrical or mechanical facilities in the Leased Premises or
     which the Landlord does not approve of and the Tenant will not bring upon
     the Leased Premises any machinery, equipment or thing which might, in the
     opinion of the Landlord damage the Leased Premises or the Project.

11.08 Removal and Restoration by the Tenant

     (a)  The alterations, decorations, additions and improvements made by the
          Tenant, or made by the Landlord on the Tenant's behalf, immediately
          become the property of the Landlord and will not be removed from the
          Leased Premises except that, (i) the Tenant may, during the Term, in
          the usual course of its business, and with the prior written consent
          of the Landlord, remove any trade fixtures which it installed, but
          only if they have become excess for the Tenant's purposes or the
          Tenant is substituting new and similar trade fixtures, and the Tenant
          is not in default under this Lease, and (ii) the Tenant will, at the
          expiration of the Term, at its costs, remove all the trade fixtures
          installed in the Leased Premises and those leasehold improvements and
          fixtures installed in the Leased Premises which the Landlord requires
          to be removed.

     (b)  Upon the removal, in accordance with subparagraph (a) above, of the
          trade fixtures, leasehold improvements and fixtures installed in the
          Leased Premises, title to them will revert to the Tenant.

     (c)  To avoid doubt, it is stated here that the Tenant's trade fixtures do
          not include any, (i) heating ventilating or air-conditioning systems,
          facilities and equipment in or serving the Leased Premises, (ii) floor
          coverings, ceilings, partitioning, draperies, (iii) light fixtures,
          (iv) washroom fixtures and hot water tank, (v) electrical house
          service including transformer, (vi) internal stairways, (vii) show
          windows and doors, and (viii) signs, all of which are leasehold
          improvements.

11.09 Notice by the Tenant

     The Tenant will, when it becomes aware of it, or when the Tenant, acting
     reasonably, should have become aware of it, notify the Landlord of any
     damage to, or deficiency or defect in the Project, including the Leased
     Premises, and any equipment or utility systems, or installations located in
     it, whether or not the Landlord has obligations to repair the damage, or
     remedy the deficiency or defect.

11.10 Liens

     The Tenant will promptly pay its contractors, materialmen, suppliers and
     workmen and will do everything necessary to ensure that no lien is
     registered against the Property or any part of it, or against the
     Landlord's interest in the Project, or against the Tenant's interest in the
     Leased Premises, and if such a lien is made, filed, or registered, the


                                       25
<PAGE>


     Tenant will discharge it or cause it to be discharged immediately at the
     Tenant's expense. If the Tenant fails to complete this obligation, the
     Landlord, in addition to its other remedies, may, but will not be required
     to, discharge the lien by paying the amount claimed into court or directly
     to the Lien claimant and the amount so paid together with the costs and
     expenses including solicitors fees (on a solicitor and his client basis)
     and a fee of fifteen (15%) percent of such costs and expenses representing
     the Landlord's overhead, will be payable as Additional Rent on demand.

11.11 Signs and Advertising

     The Tenant will not paint, affix, or display any sign, picture,
     advertisement, notice, lettering or decoration on any part of the exterior
     of or in any part of the Leased Premises which is visible from the exterior
     of the Leased Premises, without, in each case, the prior written approval
     of the Landlord. All signs erected by the Tenant will be of uniform size,
     lettering and location as the signs of the other tenants in the Project. If
     the Landlord establishes a policy for the tenants of the Project, then the
     Landlord will be entitled to erect all of the signs and other advertising
     material in or on the Project advertising the respective tenants business
     operations. The cost of the sign and the install f it will be paid by the
     Tenant.

     extermination contractor the Landlord directs and at the intervals which
     the Landlord requires.

11.13 Excess Waste or Garbage

     Landlord may, at the Tenant's sole expense, make or require the Tenant to
     make special arrangements for removal and disposal of waste or garbage at
     the Tenant's sole expense.

                    DAMAGE AND DESTRUCTION AND EXPROPRIATION

12.01 Destruction of the Leased Premises

     (a)  If the Leased Premises are destroyed or damaged (including, but not
          limited to, smoke and water damage) as a result of a peril required to
          be insured against by the Landlord under Section 10.05 or otherwise
          insured against by the Landlord, and not caused by the Tenant, the
          following provisions apply;

          (i)  if the Leased Premises are rendered partly untenantable, then,
               subject to Section 12.02 (a), the Landlord will do the Landlord's
               Work and Minimum Rent (but not Additional Rent) will abate
               proportionately to the part of the Leased Premises rendered
               untenantable from the date of the damage or destruction until the
               Landlord has completed the Landlord's Work; "Landlord's Work" in
               this Article XII means the reconstruction or repair of the floor,


                                       26
<PAGE>


               walls and roof of the Leased Premises to the extent which the
               Architect determines is necessary to enable the Tenant to do the
               repairs and replacements described in Section 11.01 (a).

          (ii) if the Leased premises are rendered wholly untenantable, the
               Landlord will, subject to Section 12.02 (a), complete the
               Landlord's Work and Minimum Rent (but not Additional Rent) will
               abate completely from the date of the damage or destruction until
               the Landlord's Work is completed, and

          (iii) if the Leased Premises are not rendered untenantable in whole or
               in part, there will be no abatement of rent subject to Section
               12.02 (a) the Landlord will complete the Landlord's Work.

     (b)  When the Landlord notifies the Tenant that the Landlord's Work has
          been substantially completed, the Tenant will complete all work other
          than the Landlord's Work required to fully restore the Leased Premises
          and will reopen the Leased Premises to the public for business fully
          fixtured, on the earliest date possible but in any case at lease as
          early as thirty (30) days after notice that the Landlord's Work is
          substantially completed. The Tenant acknowledges that the Landlord is
          not required to rebuild or restore the Leased Premises to the same
          condition as existed before the damage or destruction.

12.02 Destruction of the Project

     (a)  Despite anything else in this Lease, if twenty-five (25%) percent of
          the Rentable Area of the Project is damaged or destroyed or becomes
          unfit for occupancy or unsafe (including, but not limited to smoke and
          water damage), then, whether or not the Leased Premises are damaged or
          destroyed, the Landlord may, within ninety (90) days following the
          occurrence, terminate this Lease by notice in writing to the Tenant
          with termination to be effective on the thirtieth (30th) day after the
          notice is given. Minimum Rent and Additional Rent will be due and
          payable without abatement until the effective date of the termination,
          unless the Leased Premises have been destroyed or damaged in which
          case Minimum Rent will abate as provided in Section 12.01 (a) above.

     (b)  If the Landlord does not elect to terminate this Lease in accordance
          with Section 12.01 (a), the Landlord will reconstruct or repair, if
          necessary, that part of the Project immediately adjacent to the Leased
          Premises, but only to the extent of the Landlord's responsibilities
          under the leases for the Leasable Premises. If the Landlord
          reconstructs or rebuilds the Project or any part of it, the Landlord
          may use plans and specifications and working drawings other than those
          used in the original construction of the Project or any part of it.

12.03 Expropriation

     (a)  The Landlord and the Tenant will co-operate with each other in respect
          of any expropriation of any part of the Leased Premises or


                                       27
<PAGE>


          the Project so that each receives the maximum award for which they are
          respectively entitled. If part of the Project (other than the Leased
          Premises) is expropriated, the full proceeds accruing or awarded, will
          belong solely to the Landlord and the Tenant will assign to the
          Landlord any rights which it may have or acquire in respect of those
          proceeds and will not execute the documents which in the Landlord's
          opinion may be necessary to give effect to this intention.

     (b)  If more than fifty (50%) percent of the Rentable Area of the Project
          or more than fifty (50%) percent of the Common Areas and Facilities is
          expropriated, or if reasonable access to the Leased Premises is
          materially and adversely affected by the expropriation then the
          Landlord may terminate this Lease as of the date the expropriated
          interest vests in the expropriating authority and the Tenant will have
          no claim against the Landlord for the value of any expired Term or for
          any damages otherwise. If the Landlord does not terminate this Lease
          as provided above, there will not be any reduction or abatement of
          Rent but if any part of the Leased Premises is expropriated and the
          Rentable Area of the Leased Premises is reduced, that reduced Rentable
          Area will be adjusted for the purposes of Minimum Rent and Additional
          Rent.

12.04 Architect's Certificate

     The certificate of the Architect binds the parties as to each of the
     matters for determination under this Article.

                                  ARTICLE XIII
               ASSIGNMENT, SUBLETTING, PARTING WITH POSSESSION AND
                                CORPORATE CONTROL

13.01 Consent Required

     (a)  The Tenant will not assign this Lease in whole or in part, nor sublet
          all or any part of the Leased Premises, nor mortgage or encumber this
          Lease or the Leased Premises or any part of them nor will it permit
          the occupation of, or part with or share possession of all or any part
          of the Leased Premises by any Person (all of which transactions are
          referred to in this Article XIII as "Transfers") without the prior
          written consent of the Landlord in each instance, which consent,
          subject to Section 13.01 (b) will not be unreasonably withheld. The
          consent by the Landlord to any Transfer, will not constitute a waiver
          of the necessity for the Landlord's consent to any subsequent or other
          Transfer. This restriction on Transfers applies also to any Transfer
          by operation of law and no Transfer will be considered to take place
          by reason of the failure by the Landlord to give notice to the Tenant
          within thirty (30) days as is required by Section 13.02.

     (b)  Despite Section 23 of The Landlord and Tenant Act of Ontario, or any
          statute passed to take the place of or to amend that Act, the Landlord
          will rot be considered to be unreasonably withholding its consent, and
          may, whether or not it would otherwise be considered unreasonable,


                                       28

          (ii) whether the transferee has a good credit rating, Is of
               substantial means, Is capable of financing its acquisition of the
               Tenant's business and the Lease on terms and conditions at least
               as favourable as those originally obtained by the Tenant and
               whether the transferee has a history of successful business
               operations in the business conducted on the Leased Premises;

          (iii) whether the transferee or any partnership of which the
               transferee was a member at the time or a corporation (other than
               one described in Section 13.04 (b) of which the Tenant at the
               time was a shareholder, has become bankrupt or insolvent or has
               defaulted (other than by a minor technical default) under the
               terms or any lease for commercial or office premises whether
               leased from the Landlord or other parties;

          (iv) whether any Mortgagee, whose consent is required, regardless of
               its reason for doing so, refuses to consent to the Transfer;

          (v)  whether the transferee is an existing tenant of the Project, and

          (vi) whether the Landlord has available for leasing to the transferee
               other space in the Project or any other comparable project owned
               or operated by the Landlord.

     (c)  If there is a permitted Transfer of this Lease, the Landlord may
          collect Rent from the transferee and apply the net amount collected to
          the Rent required to be paid under this Lease, but no acceptance by
          the Landlord of any payments by a transferee as tenant or a release of
          the Tenant from the performance of its obligations under this Lease.
          Any document effecting the transfer of this Lease and every document
          consenting to the Transfer will be prepared by the Landlord or its
          solicitors and the legal costs and other expenses in connection with
          the document will be paid to the Landlord by the Tenant as Additional
          Rent upon demand. Any consent by the Landlord will be subject to the
          following conditions:

          (i)  the transferee will promptly execute an agreement agreeing with
               the Landlord to be bound by all the Tenants's obligations under
               this Lease as if the transferee had originally executed this
               Lease as tenant;

               Tenant will remain jointly and severally liable with the
               transferee on this Lease and will not be released from any
               obligations under this Lease as amended from time to time;


                                       29
<PAGE>


          (iii) if the transferee agrees to pay to the Tenant a Rent or other
               amount, in respect of its use of the Leased Premises or any part
               of it in excess of the Rent payable by the Tenant to the
               Landlord, the Rent under this Lease will be increased so that it
               equals the Rent or amount payable by the transferee to the
               Tenant;

          (iv) if the transferee agrees to pay to the Tenant or party other than
               the Landlord in respect of a Transfer of all or any part of this
               Lease, any amount, or any benefit, then it will pay to the
               Landlord as Additional Rent, on demand, an amount equal to the
               value of the amount or benefit;

               employed by the Landlord at the time of the Transfer;

          (vi) if the rate of the annual Minimum Rent is increased, the deposit
               mentioned in Section 4.02 (d) will be increased accordingly.

13.02 Landlord's Option

     If the Tenant intends to effect a Transfer, it will notify the Landlord and
     will provide with the notice full information concerning the transferee,
     including but not limited to, complete credit, financial, and business
     information. Within thirty (30) days after the date the Tenant give to the
     Landlord the information mentioned above, the Landlord will notify the
     Tenant in writing that, (a) it consents to the Transfer, (b) that it does

          but not limited to, the pipes, conduits, wiring, ducts and other
          installations in the Leased Premises, where necessary to serve another
          part of the Project, and for that purpose, the Landlord may take

     (c)  If the Tenant is not personally present to permit an entry into the
          Leased Premises at any time when for any reason an entry is necessary
          or permitted, the Landlord or its agents may forcibly enter them
          without liability and without affecting this Lease. Any entry by the
          Landlord on the Leased Premises in accordance with this Section is not
          a re-entry or a breach of covenant for quiet enjoyment.

     after the date of request by the Landlord the Tenant has not executed and
     delivered them, the Tenant hereby irrevocably appoints the Landlord as the

     the name of the Tenant the instruments and certificates or the Landlord may
     terminate this Lease without incurring any liability.

15.04 Financial Information

     The Tenant will, upon request, provide the Landlord with such information
     as to the Tenant's or the Indemnifier's financial standing and corporate
     organization as the Landlord or the Mortgagee requires. Failure of the

     Lease.

                                  ARTICLE XVI

16.02 Rights of the Landlord

     Upon the occurrence of any Event of Default the following provisions apply:

     (a)  The Landlord will be entitled to re-enter the Leased Premises and
          remove all property from the Leased Premises and the property may be
          sold or disposed of by the Landlord as it considers advisable or may
          be stored in a public warehouse or elsewhere at the cost and for the
          account of the Tenant, all without service of notice or resort to
          legal process and without the Landlord being guilty of trespass or
          being liable for any loss or damage which may be occasioned, and

     (b)  The Landlord may without notice re-enter and take possession of the
          Leased Premises as though the Tenant or any occupant or occupants of
          the Leased Premises was or were holding over after the expiration of
          the Term without any right whatever, and this Lease and the Term will
          be terminated.

     (c)  If the Landlord elects to re-enter the Leased Premises as provided in
          this Article, or if it takes possession pursuant to legal proceedings
          or pursuant to any notice provided for by law, it may either terminate
          this Lease or it may from time to time, without terminating this
          Lease, make those alterations and repairs which are necessary in order
          to relet the Leased Premises or any part of them for the term or terms
          (which may be for a term extending beyond the Term) and at the Rent
          and upon those other terms, covenants and conditions which the
          Landlord in its discretion considers advisable. Upon each reletting,
          the Rent received by the Landlord from the reletting will be applied,
          first to the payment of any indebtedness other than Rent due under
          this Lease from the Tenant to the Landlord; second to the payment of
          any costs and expenses of the reletting including brokerage fees and
          solicitors fees and the costs of the alterations and repairs; third to
          the payment of Rent due and unpaid under this Lease, and the residue
          if any will be held by the Landlord and applied as payment of future
          Rent as it becomes due under this Lease. If the Rent received from the


                                       34
<PAGE>


          reletting during any month is less than that to be paid during that
          month by the Tenant under this Lease, the Tenant will pay the
          deficiency, which will be calculated and paid monthly in advance on or
          before the first (1st) day of each month. No re-entry or taking
          possession of the Leased Premises by the Landlord will be construed as
          an election on its part to terminate this Lease unless a written
          notice of that intention is given to the Tenant. Despite any reletting
          without termination, the Landlord may at any time afterwards elect to
          terminate this Lease for the previous breach. If the Landlord at any
          time terminates this Lease for any breach, in addition to any other
          remedies it may have, it may recover from the Tenant all damages it
          incurs by reason of the breach including the costs of recovering the
          Leased Premises, solicitors fees (on a solicitor and his client basis)
          and including the worth at the time of the termination, of the excess,
          if any, of the amount of Rent and charges equivalent to Rent required
          to be paid under this Lease for the remainder of the stated Term over
          the then reasonable rental value of the Leased Premises for the
          remainder the stated Term. All of the mentioned amounts will be
          immediately due and payable by the Tenant to the Landlord, and

     (d)  The full amount of the current month's instalment of Minimum Rent and
          Additional Rent together with the next three (3) months instalments of
          Minimum Rent and Additional Rent, all of which will be deemed to be
          accruing on a day to day basis, will immediately become due and
          payable as accelerated Rent, and the Landlord may immediately distrain
          for that accelerated Rent together with any arrears.

16.03 Expenses

     If legal action is brought for recovery of possession of the Leased
     Premises, for the recovery of Rent or any other amount due under this
     Lease, or because of the breach of any other terms, covenants or conditions
     contained in this Lease on the part of the Tenant to be kept or performed,
     and a breach is established, the Tenant will pay to the Landlord all the
     expenses incurred in connection with it, including solicitor's fee (on a
     solicitor and his client basis), unless a court otherwise awards.

16.04 Removal of Chattels

     If the Tenant removes its goods and chattels from the Leased Premises, the
     Landlord may follow them for thirty (30) days as provided in The Landlord
     and Tenant Act of Ontario.

16.05 Waiver of Exemption from Distress

     Despite anything contained in Section 30 of The Landlord and Tenant Act of
     Ontario or any Statute passed to take its place or amend it, none of the
     goods and chattels of the Tenant at any time during the Term, on the Leased
     Premises, will be exempt from levy by distress for Rent in arrears and if
     any claim is made for such an exemption by the Tenant, or if distress for
     Rent in arrears and if any claim is made for such an exemption by the
     Tenant, or if distress is made by the Landlord, this Section may be pleaded
     as an estoppel against the Tenant in any action brought to test the right


                                       35
<PAGE>


     of the levying upon any of those goods which are named as exempted in any
     Sections of that Actor any amendments of it. The Tenant waives the rights
     which it has or which it might have or which it might have had under any
     Section of that Act, or any amendments of it, where it not for this
     provision.

16.06 Landlord's Right to Cure the Tenant's Default or Perform the Tenant's
      Covenants

     In addition to its other rights and remedies, the Landlord, if the Tenant
     defaults under this Lease, may remedy or attempt to remedy the default of
     the Tenant and in so doing may make any payments due or alleged to be due
     by the Tenant to third parties and may enter upon the Leased Premises to do
     any work or other things on them in which case all the Landlord's costs and
     expenses will be payable together with a fee of fifteen (15%) percent of
     all those costs and expenses representing the Landlord's overhead, as
     Additional Rent on demand. The Landlord will not be liable for any loss or
     damage resulting from any action or entry by the Landlord under this
     Section and will not be considered to have breached any covenant for quiet
     enjoyment.

16.07 Remedies Generally

     Mention in this Lease of any particular remedy of the Landlord for a
     default or Event of Default by the Tenant does not preclude the Landlord
     from any other remedy in respect of it. No remedy will be exclusive or
     dependent upon any other remedy but the Landlord may from time to time
     exercise one or more of its remedies generally or in combination, those
     remedies being cumulative and not alternative. Whenever the Tenant seeks a
     remedy in order to enforce the observance or performance of one or more of
     the obligations of the Landlord under this Lease, the Tenant's only remedy
     will be for damages. The Tenant will not apply for injunctive relief and
     this provision may be pleaded as an estoppel in any proceedings taken by
     the Tenant to obtain injunctive relief.

                                  ARTICLE XVII
                                  MISCELLANEOUS

17.01 Rules and Regulations

     The Rules and Regulations adopted and promulgated by the Landlord from time
     to time are a part of this Lease as set out in Schedule "C" attached, and
     the Tenant will comply with and observe them. The Rules and Regulations
     will be adopted and promulgated by the Landlord acting reasonably. The
     Tenant's failure to keep and observe the Rules and Regulations is a default
     under this Lease in the same manner as if the Rules and Regulations were
     set out as covenants in this Lease. The Landlord may from time to time
     amend or supplement the Rules and Regulations. Notice of the Rules and
     Regulations and amendments and supplements, if any, will be given to the
     Tenant and the Tenant's obligation to comply with and observe them rises
     upon its being notified. The Rules and Regulations will not conflict with
     or contradict the other provisions of this Lease. The Landlord will not be
     responsible to the Tenant for non-observance or violation by other tenants
     or occupants of Leasable Premises, of the Rules and Regulations or of the
     terms, covenants or conditions in any other lease of premises in the
     Project.

17.02 Overholding

     (a)  If the Tenant remains in possession of the Leased Premises after the
          end of the Term with the consent of the Landlord but without having
          executed and delivered a new lease, the Tenant will be considered to
          be occupying the Leased Premises as a Tenant from month to month on
          the same terms and conditions as are set out in this Lease (including
          the payment of Additional Rent).

     (b)  If the Tenant remains in possession of the Leased Premises after the
          end of the Term without the written consent of the Landlord it will be
          liable for payment of Rent at the rate equal to twice the rate of
          Minimum Rent and Additional Rent which it was responsible for paying
          during the last year of the Term.

17.03 Successors

     The rights and liabilities granted to or imposed upon the respective
     parties to this Lease, extend to and bind the successors and assigns of the
     Landlord and the heirs, executors, administrators and permitted successors

     assignee of the Tenant unless the assignment to the assignee has been

     performance of, and will be and continue to be subject to the terms,
     covenants and conditions of this Lease, whether or not that Person ceases
     to be a member of the Tenant Partnership or successor Tenant Partnership.

17.05 Waiver

     The waiver by the Landlord of any breach of an obligation by the Tenant is
     not to be considered a waiver or any subsequent breach of the obligation or
     any other obligation. The subsequent acceptance of Rent by the Landlord is
     no to be construed as a waiver of any preceding breach by the Tenant of any
     obligation under this Lease, regardless of the Landlord's knowledge of the
     preceding breach at the time of acceptance of that Rent. No obligation will
     be considered to have been waived by the Landlord unless the waiver is in
     writing by the Landlord.

17.06 Accord and Satisfaction

     No payment by the Tenant or receipt by the Landlord of a lesser amount that
     the monthly payment of Minimum Rent is to be construed as other than on
     account of the earliest stipulated Minimum Rent, nor is any endorsement or
     statement on any cheque or any letter accompanying any cheque or payment as
     Rent to be considered an acknowledgement of full payment or an


                                       37
<PAGE>


     accord and satisfaction, and the Landlord may accept payment and cash

     the Rent or pursue its other remedies.
