3.03  DELAYED POSSESSION - If the Landlord is unable to deliver possession of
all or any portion of the Leased Premises by the Commencement Date, this Lease
shall remain in full force and effect and the Tenant shall take possession of
the Leased Premises on the date when the Landlord delivers possession of all of
the Leased Premises, which date shall be conclusively established by notice in
writing from the Landlord to the Tenant at least 10 days before such date. The
Landlord shall not be liable to the Tenant for any loss, damage or inconvenience
resulting from any delay in delivering possession of the Leased Premises but,
unless the delay is caused by or attributable to the Tenant, its servants,
agents or Independent contractors, no Rent shall be payable by the Tenant for
the period prior to the date on which the Landlord can deliver possession of all
of the Leased Premises, unless the Tenant elects to take possession of a portion
of the Leased Premises, in which case Rent shall be payable in respect thereof
from the date such possession is so taken. Despite anything contained to the
contrary in this Section 3.03, if the Landlord is of the opinion that it is
unable to deliver possession of all or any part of the Leased Premises by the
expiration of 6 months from the Commencement Date, the Landlord shall have the
right to terminate this Lease upon written notice to the Tenant, whereupon
neither party shall have any liability to the other.

3.04  ACCEPTANCE OF LEASED PREMISES - Taking possession of all or any portion of
the Leased Premises by the Tenant shall be conclusive evidence as against the
Tenant that the Leased Premises or such portion thereof and the Common Elements
are in satisfactory condition on the date of taking possession, subject only to
latent defects and to deficiencies (if any) listed in writing in a notice
delivered by the Tenant to the Landlord not more than 10 days after the date of
taking possession.

                              ARTICLE 4.00 - RENT

4.01  RENT - The Tenant shall pay to the Landlord as Rent for the Leased
      Premises the aggregate of:

(a)   Basic Rent in respect of each year of the Term, payable in advance and
      without notice or demand in monthly installments as set out in Item 8 of
      the Term Sheet commencing on the Commencement Date and on the first day of
      each calendar month thereafter during the Term;

(b)   Tenant's Occupancy Costs, which shall include Tenant's Proportionate Share
      of Taxes, during the Term, payable in monthly installments at the times
      and in the manner provided in Section 4.06; and

                                                                          Page 2
<PAGE>

(c)   all amounts (other than payments under Subsections 4.01 (a) and (b))
      payable by the Tenant to the Landlord under this Lease, at the times and
      in the manner provided in this Lease or, if not so provided, as reasonably
      required by the Landlord.

4.02  SECURITY DEPOSIT - The Landlord acknowledges receipt on or before the
Commencement Date of the amount set out in Item 6(a) of the Term Sheet (the
"Security Deposit") to be held by the Landlord, without any liability whatsoever
on the part of the Landlord for the payment of interest thereon, as a security
deposit for the faithful performance by the Tenant of the terms, covenants and
conditions of this Lease during the Term hereof and not to be applied on account
of Rent except as otherwise provided in this Section 4.02. The Security Deposit
will not be a limitation on the Landlord's damages or other rights and remedies
available under this Lease or at law or equity, nor shall the Security Deposit
be either a payment of liquidated damages or an advance payment of Rent. The
Landlord shall have no fiduciary responsibilities or trust obligations
whatsoever with regard to the Security Deposit and shall not assume the duties
of a trustee for the Security Deposit. The Security Deposit shall not be
mortgaged, assigned or encumbered by the Tenant and the Landlord shall not be
bound by any such mortgage, assignment or encumbrance. It is understood and
agreed between the parties that any portion of the Security Deposit may, at the
Landlord's option, be applied toward the payment of overdue or unpaid Rent and
may also be applied as compensation to the Landlord for any loss or damage
sustained with respect to the breach on the part of the Tenant of any terms,
covenants and conditions of this Lease, provided in all cases, however, that the
Tenant's liability hereunder is not limited to the amount of the Security
Deposit. If during the Term any portion of the Security Deposit is so applied,
then the Tenant shall on written demand deliver to the Landlord a sufficient
amount in cash or by certified cheque to restore the Security Deposit to the
original sum deposited. The Landlord shall refund to the Tenant after the expiry
date of this Lease any portion of the Security Deposit not used by the Landlord
after application by the Landlord to any damage incurred by the Landlord by
reason of the default of the Tenant under the terms of this Lease. It is further
provided that the Landlord will be discharged from all liability to the Tenant
with respect to the Security Deposit to the extent that it is transferred to any
purchaser of the Landlord's interest in the Leased Premises.

4.03  INTENT - It is the stated purpose and intent of the Landlord and the
Tenant that this Lease and the Rent shall be fully net to the Landlord.

4.04  PAYMENT OF RENT - GENERAL - All amounts payable by the Tenant to the
Landlord pursuant to this Lease shall be deemed to be Rent and shall be payable
and recoverable as Rent in the manner herein provided and the Landlord shall
have all rights against the Tenant for default in any such payment as in the
case of arrears of Rent. Rent shall be paid to the Landlord in lawful money of
Canada, without deduction, abatement or set-off, at the local address of the
Landlord set out in Item 1 of the Term Sheet or to such other Person or such
other address as the Landlord may from time to time designate in writing. The
Tenant's obligation to pay Rent shall survive the expiration or earlier
termination of this Lease. Any Rent or other sum received or accepted by the
Landlord and paid by anyone other than the Tenant, on behalf of the Tenant,
shall not release or in any way affect the covenants of the Tenant set out in
this Lease and shall not be deemed to constitute or evidence the Landlord's
consent to a Transfer under Article 12.00. Any Rent or other sum received by the
Landlord from or for the account of the Tenant while the Tenant is in default
under this Lease may be applied at the Landlord's option to the satisfaction in
whole or in part of any of the obligations of the Tenant then due under this
Lease in such manner as the Landlord sees fit regardless of any designation or
instruction of the Tenant to the contrary.

4.05  PARTIAL MONTH - If the Commencement Date is a day other than the first day
of a calendar month, or if the Term ends on any day other than the last day of a
calendar month, Rent for the fractions of a month at the beginning and at the
end of the Term shall be adjusted pro rata on a per diem basis.

4.06  PAYMENT OF TENANT'S OCCUPANCY COSTS

(1)   ESTIMATE AND PAYMENT

(a)   The Landlord shall deliver to the Tenant a written estimate or a written
      revised estimate of: (i) Tenant's Occupancy Costs for each Fiscal Year;
      and (ii) Tenant's Proportionate Share of those Taxes that are imposed
      against the Project or any part of it including the Common Elements. The
      Tenant shall pay to the Landlord the amount so estimated in equal monthly
      installments (except as otherwise required in this Section 4.06 with
      respect to Property Taxes) in advance over that Fiscal Year simultaneously
      with the Tenant's payments on

                                                                          Page 3
<PAGE>

      account of Basic Rant. If the Landlord does not deliver to the Tenant such
      an estimate, the Tenant shall continue to pay Tenant's Occupancy Costs and
      Tenant's Proportionate Share of Taxes based on the last such estimate
      delivered by the Landlord until a further estimate is delivered by the
      Landlord and the next payment on account of Tenant's Occupancy Costs or
      Taxes shall be adjusted to take into account any over or under payment in
      the preceding installments paid in the Fiscal Year to which the estimate
      or revised estimate relates. Notwithstanding the foregoing, as soon as
      bills for all or any portion of amounts included in Operating Costs
      (including, without limitation, Taxes) as so estimated are received, the
      Landlord may bill the Tenant for the Tenant's Proportionate Share thereof
      and the Tenant shall pay the Landlord such amounts so billed (less all
      amounts previously paid on account by the Tenant on the basis of the
      Landlord's estimate as aforesaid) as Rent within 5 days following demand
      therefor.

(b)   Within a reasonable time after the date in each calendar year when the
      final installment of Property Taxes is due in respect of commercial
      properties generally in the municipality in which the Project is located
      (the "Final Payment Date"), the Landlord shall deliver a statement (the
      "Tax Statement") to the Tenant that: (i) specifies the Tenant's
      Proportionate Share of Taxes for the Property Tax Year, and (ii) sets out
      the total (the "Prepayment Total") of amounts payable under this
      Subsection 4.06(1)(b) that have been paid by the Tenant between the Final
      Payment Date in the previous Property Tax Year and the Final Payment Date
      of the current Property Tax Year. If the Prepayment Total, less any
      amounts that were previously credited to the Tenant, and any amounts paid
      for arrears in respect of previous Property Tax Years, (the "Net
      Prepayment Total") is less than the Tenant's Proportionate Share of Taxes
      specified in the Tax Statement, the Tenant shall pay the deficiency with
      the next monthly payment of Basic Rent. If the Net Prepayment Total
      exceeds the Tenant's Proportionate Share of Taxes specified in the Tax
      Statement, the Landlord shall, unless the Tenant is then in default under
      this Lease, credit the excess to the Tenant on account of the next
      succeeding payments of Tenant's Occupancy Costs. The Landlord may estimate
      Property Taxes for the Property Tax Year following the then current
      Property Tax Year and the Tenant shall continue after the Final Payment
      Date to make monthly payment in advance, in amounts determined by the
      Landlord, for periods determined by the Landlord. The monthly payments
      paid by the Tenant after the Final Payment Date shall be credited against
      the Tenant's Proportionate Share of Taxes for the subsequent Property Tax
      Year.

(c)   Any portion of the Tenant's Proportionate Share of Taxes accrued with
      respect to the Term or any part thereof paid by the Landlord prior to the
      Commencement Date shall be reimbursed by the Tenant to the Landlord on the
      Commencement Date or on demand thereafter. Subject to Sections 8.03 and
      8.05, the Tenant shall pay the Tenant's Proportionate Share of any
      Property Taxes or the Landlord's reasonable estimate thereof monthly in
      advance in the same manner as for payment of Tenant's Occupancy Costs.

      Notwithstanding the foregoing, the Landlord shall always have the right:

      (i)   to revise the amount of installments on account of Property Taxes
            payable by the Tenant to an amount that allows the Landlord to
            collect all Property Taxes payable by the Tenant by the final due
            date of Property Taxes for the calendar year, and/or

      (ii)  to schedule and require payment by the Tenant of installments on
            account of Property Taxes payable by the Tenant such that by the
            final due date of Property Taxes for any calendar year, the Tenant
            shall have paid to the Landlord the full amount of Property Taxes
            payable by the Tenant for such calendar year, which arrangement may
            include payment of installments by the Tenant in a calendar year on
            account of Property Taxes payable by the Tenant for the next
            calendar year; and/or

      (iii) (but not the obligation) to allocate Taxes among categories of
            rentable premises in the Project on the basis of such factors as the
            Landlord determines to be relevant, such as, by way of example, the
            types of business or activity carried on therein, the locations in
            the Project, costs of construction, relative benefits derived by
            rentable premises, relative assessment values, non-public school
            support designations and vacancies. The Landlord shall be entitled
            to adjust the Tenant's Proportionate Share of Taxes having regard to
            the category in which the Tenant is placed by the Landlord. In
            determining the share of Taxes which is payable by the Tenant
            pursuant to this Lease, Taxes shall include such additional amounts
            as would have formed part of the Taxes had the Project been fully
            assessed during the whole of the relevant period as fully completed
            and fully occupied by tenants,

                                                                          Page 4
<PAGE>

            with no special exemptions or reductions, and without taking into
            account any actual or potential reduction of Taxes or change of
            assessment category or class for rentable premises within the
            Project which are vacant.

(2)   ANNUAL STATEMENT AND ADJUSTMENT -The Landlord shall deliver to the Tenant
within 120 days after the end of each Fiscal Year or as soon after that date as
the same shall be prepared by or for the Landlord, a written statement setting
out in reasonable detail the amount of Operating Costs and Tenant's Occupancy
Costs for such Fiscal Year. If the total of monthly installments of Tenant's
Occupancy Costs actually paid by the Tenant to the Landlord during that Fiscal
Year differs from the amount of Tenant's Occupancy Costs payable for that Fiscal
Year under Subsection 4.01(b), the Tenant shall pay to the Landlord or, if the
Tenant is not in default, the Landlord shall credit to the Tenant on account of
the next succeeding payments of Tenant's Occupancy Costs, as the case may be,
the difference, without Interest, within 30 days after the date of delivery of
the statement.

(3)   DISPUTES - If the Tenant disputes the Landlord's statement setting out
Operating Costs and Tenant's Occupancy Costs or the Tax Statement for any Fiscal
Year, the Tenant shall provide notice thereof in writing to the Landlord within
60 days of delivery of the statement in respect of that Fiscal Year.
Notwithstanding delivery of such notice, the Tenant shall continue to pay Rent
in accordance with the terms of this Lease. In the event of a dispute, the
determination of Operating Costs and Tenant's Occupancy Costs or Tenant's
Proportionate Share of Taxes as made by the Landlord's auditors shall be
conclusive and binding upon both the Landlord and the Tenant. All costs of
obtaining such determination shall be included in Operating Costs; provided that
if the Landlord's auditors confirm the Landlord's calculations within a variance
of 5%, the Tenant shall be solely responsible for the entire cost of such
determination and shall pay such coats to the Landlord forthwith upon demand. If
the Tenant and any one or more of the other tenants in the Project are
responsible to pay such costs, the Tenant shall be jointly and severally liable
with such other tenant or tenants.

4.07  ESTIMATES OF INDIRECT EXPENSES AND RESOLUTION OF DISPUTES - Any expense
not directly incurred by the Landlord but which is included in Operating Costs
may be estimated by the Landlord on whatever reasonable basis the Landlord may
select if and to the extent that the Landlord cannot ascertain the actual amount
of the expense from the party who incurred it. In the event of any disagreement
as to the amount or propriety of any amount included in Operating Costs, a
certificate of the auditor of the Landlord, acting reasonably, shall be
conclusive as to the amount of Operating Costs for any period to which such
certificate relates.

4.08  AREA DETERMINATION* - The Landlord may from time to time, as it deems
necessary, cause the Rentable Area of the Leased Premises, the Building or any
part thereof to be recalculated or remeasured and the cost thereof shall be
included in Operating Costs (except as otherwise provided in this Section 4.08).
Upon any such recalculation or remeasurement, Rent (including without limitation
Basic Rent) shall be adjusted accordingly. If any calculation or determination
by the Landlord of the Rentable Area of any premises (including the Leased
Premises) is disputed or called in question, is shall be calculated or
determined by the Landlord's architect or surveyor from time to time appointed
for that purpose, whose certificate shall be conclusive and binding upon the
parties hereto. The cost of such calculation or determination shall be included
in Operating Costs; provided that if the Tenant disputes the Landlord's
calculation or determination and the calculation and determination by the
Landlord's architect or surveyor agrees with the Landlord's calculation or
determination within a 2% variance, the Tenant shall pay the full cost of such
calculation or determination forthwith upon demand. If the Tenant and any one or
more of the other tenants in the Project are responsible to pay such costs, the
Tenant shall be jointly and severally liable with such other tenant or tenants.

If any error shall be found in the calculation of the Rentable Area of the
Leased Premises or in the calculation of Tenant's Proportionate Share, Rent
(including without limitation Basic Rent) shall be adjusted for the Fiscal Year
in which that error is discovered and for the Fiscal Year preceding the Fiscal
Year in which the error was discovered, if any, and thereafter but not for any
prior period.

Notwithstanding the above, the Landlord and Tenant agree that the area of the
Leased Premises shall be as stipulated in Item 5 of the Term Sheet, subject to
(i) any construction or redevelopment to the Building which results in an

----------
* Per hand marked revision to the original, the text of Section 7.04(b) is
incorporated from Schedule E to the original (which is here omitted).

                                                                          Page 5
<PAGE>

increase or decrease of the overall Building area; or (ii) change to the Leased
Premises as provided for in Section VI - Right to Expand and Section VIII -
Option to Lease Additional Premises.

4.09  VACANCY - If any part of the Building available for leasing is not
occupied, the Landlord shall have the right, in respect of amounts forming part
of Operating Costs which vary with occupancy, to include in Operating Costs a
larger amount of costs, which larger amount shall be based on a reasonable
estimate of the actual cost which would have been incurred if the unoccupied
parts of the Building available for leasing were occupied, it being intended
hereby that the Landlord shall obtain, to the extent reasonably possible, full
reimbursement of Operating Costs attributable to or in respect of occupied
premises, and not that: (a) the Tenant shall subsidize Operating Costs incurred
by the Landlord attributable to or in respect of vacant premises; or (b) the
Landlord shall recover more than actual Operating Costs.

4.10  METHOD OF PAYMENT

(1)   Unless the Landlord advises otherwise in writing, the Tenant shall provide
to the Landlord on or before the Commencement Date and thereafter on or before
the beginning of each Fiscal Year during the Term and within 10 days after
delivery of the Landlord's estimate of any payment constituting Rent, postdated
cheques in the amount of Rent for each month during that Fiscal Year.

(2)   At the Landlord's request, the Tenant shall participate in a
pre-authorized payment plan whereby the Landlord will be authorized to debit the
Tenant's bank account each month or from time to time for Rent payable on a
monthly basis, and any amount payable provisionally on an estimated basis. The
Tenant hereby undertakes to execute and deliver such documents as may reasonably
be required to give full force and effect to this Subsection 4.10(2) within 5
days of such request.

                       ARTICLE 5.00 - USE AND OCCUPATION

5.01  USE OF LEASED PREMISES - The Tenant shall use and occupy only the usable
part of the Leased Premises and only for office purposes to carry on the
business set out in Item 9 of the Term Sheet and shall not use or permit the
Leased Premises or any part thereof to be used or occupied for any other purpose
or business except as otherwise expressly permitted under this Lease or by any
Person other than the Tenant. The Tenant shall be responsible for obtaining at
its expense all necessary approvals, licenses and permits, including but not
limited to zoning, development, building, occupancy and business approvals,
licenses and permits, for its intended use of the Leased Premises and shall
submit all applications for such approvals, licenses and permits to the Landlord
for its consent (which consent, if the application pertains to the zoning
applicable to the Project or may adversely affect the value or use of the
Project or any part thereof, may be arbitrarily withheld by the Landlord) prior
to making application. Notwithstanding the Landlord's consent to an application,
the Tenant shall indemnify and defend the Landlord and save it harmless from and
against any and all Claims incurred or suffered by the Landlord directly or
indirectly arising out of the Tenant's application for such approvals, licenses
or permits or the resulting approvals, licenses and permits with respect to the
use, intended or otherwise, of the Leased Premises whether such Claims are in
respect of the Leased Premises or in respect of the Building or the Project. The
Landlord makes no representation whether or not necessary approvals can be
obtained for the Tenant's use or intended use. The Landlord makes no
representation or warranty, express or implied, that the present or future use
of the Leased Premises, if such use is anything other than office use, is
legally fit for the intended use, or compiles with any law, by-law or regulation
governing the use of the Leased Premises.

5.02  COMPLIANCE WITH LAWS - The Tenant shall promptly and at its own cost
comply with all present and future laws, regulations and orders relating to, and
obtain and maintain in force all approvals, permits, licenses and registrations
required for, any of the following:

(a)   the occupation or use of and the conduct of any business in or from the
      Leased Premises;

(b)   the condition of the Leasehold Improvements, fixtures, furniture and
      equipment installed therein;

                                                                          Page 6
<PAGE>

(c)   Pollutants and the protection of the environment so far as those laws,
      regulations and orders or any of them relate to the Project; and

(d)   the making by the Tenant of any repairs, changes or improvements in or to
      the Project;

and the Tenant shall immediately give written notice to the Landlord of the
occurrence of any event in the Leased Premises constituting an offence
thereunder or being in breach thereof and if the Tenant shall, either alone or
with others, cause the happening of any such event, the Tenant shall immediately
give the Landlord notice to that effect and thereafter give the Landlord from
time to time written notice of the extent and nature of the Tenant's compliance
with the foregoing provisions of this Section.

The Tenant agrees that if the Landlord determines in its sole discretion that
the Landlord, its property, its reputation or the Leased Premises or any one or
more of the foregoing is placed in any jeopardy, as determined by the Landlord,
by the requirements for any work required to ensure compliance with the
foregoing provisions of this Section 5.02, or the Tenant is unable to fulfill
its obligations under this Section, the Landlord may itself undertake such work
or any part thereof at the cost and expense of the Tenant.

The Tenant shall, at its own expense, remedy any damage to the Leased Premises
caused by such event or work or by the performance of the Tenant's obligations
under this Section.

If alterations or improvements to the Leasehold Improvements onto the Leased
Premises are necessary to comply with any of the foregoing provisions of this
Section or with the requirements of Insurance carriers, the Tenant shall
forthwith complete such work, complying always with the applicable provisions of
this Lease, to the extent that it can be done within the Leased Premises and in
any event shall pay the entire cost of alterations and improvements so required.

In the event that structural repairs or upgrading of the Building, including but
not limited to seismic upgrading, is required to permit the Tenant's use, the
Landlord may, at its sole discretion, terminate the Lease.

5.03  PROHIBITED USES - The Tenant shall not commit, cause or permit any
nuisance in or about or any damage to the Leased Premises or any part thereof,
the Building, the Project or any of the Leasehold Improvements or goods or
fixtures therein, any overloading of the floors of the Leased Premises or any
use or manner of use causing annoyance to other tenants or occupants of the
Project. Without limiting the generality of the foregoing, the Tenant shall not
use or permit the use of any portion of the Leased Premises for any dangerous,
illegal, noxious, odorous or offensive trade, business or occurrence. The Tenant
shall keep the Leased Premises free of debris, Pollutants and anything of a
dangerous, noxious, odorous or offensive nature or which could create a fire
hazard (through undue load on electrical circuits or otherwise) or vibration,
heat or noise detectable outside the Leased Premises in the sole discretion of
the Landlord. The Tenant shall not use equipment in the Leased Premises in a
manner that results in its being seen or heard outside the Leased Premises.

5.04  COMMON ELEMENTS - The Tenant and its employees and invitees shall be
entitled to use, in common with others entitled thereto, for purposes for which
they are intended and only during such hours as the Landlord may designate from
time to time, the Common Elements. The Tenant and its employees and invitees
shall not obstruct the Common Elements or use the Common Elements other than for
their intended purposes and then only in accordance with the rules and
regulations set by the Landlord from time to time.

5.05  HAZARDOUS USE - The Tenant shall not do, omit to do or permit to be done
anything which will cause or may have the effect of causing the cost of the
Landlord's insurance in respect of the Project or any part thereof to be
increased at any time during the Term or any policy of insurance on or relating
to the Project to be subject to cancellation. Without waiving or limiting the
foregoing prohibition, the Landlord may demand and the Tenant shall pay to the
Landlord upon demand, the amount of any increase in the cost of insurance caused
by anything so done or omitted or permitted to be done. The Tenant shall
forthwith upon the Landlord's request comply with the requirements of the
Landlord's insurers, cease any activity complained of and make good any
circumstance which has caused any increase in insurance premiums or the
cancellation or threatened cancellation of any insurance policy. In determining
the amount of increased premiums for which the Tenant is responsible, a schedule
or statement issued by the Person who computes the insurance rates for the
Landlord showing the components of the rate shall be conclusive

                                                                         Page 7
<PAGE>

evidence of the items that make up the rate. If any policy of insurance in
respect of the Project or any part thereof is cancelled or becomes subject to
cancellation by reason of anything so done or omitted or permitted to be done,
the Landlord may without prior notice terminate this Lease and re-enter the
Leased Premises,

5.06  TENANT'S SECURITY INTEREST - The Tenant shall not, without the Landlord's
prior written consent, create a security interest in Leasehold Improvements
installed by the Tenant or the Landlord in the Leased Premises.

5.07  RULES AND REGULATIONS - The Landlord may from time to time make and from
time to time modify by amendment, deletion, addition, rescission or replacement,

and other reasonable rules and regulations and amendments and additions thereto
as may be made by the Landlord and notified to the Tenant by mailing a copy
thereof to the Tenant or by posting same in a conspicuous place in the Building.
All such rules and regulations now or hereafter in force shall be read as
forming part of this Lease; provided that if there is a conflict between the
rules and regulations and this Lease, the terms of this Lease shall prevail. The
Landlord shall not be responsible to the Tenant for the non-observance of any
rule or regulation or the terms of any lease or agreement to lease by any other
tenant of the Project.

5.08  PERMITTED SIGNS - The Tenant shall use only such identification signs as
are prescribed by the Landlord from time to time and as comply with all
applicable by-laws, regulations and codes as to size, location, arrangement,
type of lettering, colour, appearance and design for uniform use by office
tenants in the Building. Such signs shall contain only the name under which the
Tenant carries on business.

5.09  PROHIBITED SIGNS - Except with the prior written consent of the Landlord,
which consent may be arbitrarily withheld or rescinded in the Landlord's sole

blinds, drapes, curtains, or other window coverings installed by the Landlord
from time to time. The Tenant shall keep all window coverings open or closed at

head office complete records of all goods stored on, or processed, manufactured
packaged or used in any process in the Leased Premises by the Tenant and by any
other occupant of the Leased Premises or any part thereof. The Landlord may
examine such records and the Tenant shall provide extracts from or copies
thereof all as required by the Landlord from time to time. This requirement to

performed its obligations under this Lease, including those relating to the
provision of utilities and Services, if in so doing it acts in accordance with a
directive, policy or request of an authority having jurisdiction in the field of

6.07  SUPERVISION AND EXTENDED SERVICES - The Landlord, if it shall from time to
time so elect, shall have the right to supervise the moving of furniture or
equipment of the Tenant and (in addition to supervising the Tenant's work as

the Leased Premises and the exclusive right to supervise or make deliveries to
the Leased Premises. In addition, and by arrangement with the Tenant, the
Landlord may provide extended cleaning or other Services to the Tenant in
addition to those normally supplied and referred to in this Lease. In each case,

Elements and permit others to make such use of the Common Elements as the
Landlord may from time to time determine subject, in the case of use by others,
to such terms and conditions and for such consideration as the Landlord may in
its discretion determine, provided that such uses do not materially obstruct
access to the Leased Premises and the Landlord may close all or any part or
parts of the Project to such extent as may, in the opinion of the Landlord or
any Consultants engaged by the Landlord in that regard, be legally sufficient to
prevent a dedication thereof or the accrual of rights therein to any Person or
the public.

        ARTICLE 7.00 - PAYMENT FOR SERVICES AND MAINTENANCE, REPAIR AND
                              ALTERATIONS BY TENANT

7.01 UTILITIES - In addition to the payment of Tenant's Occupancy Costs and
notwithstanding Sections 6.01 and 6.02, the Tenant shall be responsible for the
cost of all utilities including electricity supplied to the Leased Premises. The
Tenant shall not, without the prior written approval of the Landlord, which may
be arbitrarily withheld, install or cause to be installed in the Leased Premises
any equipment that will require additional utility usage or any
telecommunications lines and/or conduits in excess of that normally required for
office premises. If with the Landlord's approval such additional equipment is
installed, the Tenant shall be solely responsible for such excess utility usage.
If utilities are supplied to the Tenant through a meter common to other tenants
in the Project (there being no obligation on the Landlord to install separate
meters), the Landlord shall pay the cost of the utilities and apportion the cost
pro rata among the tenants supplied through the common meter, based on all
relevant factors including, but not limited to, the hours of use, number and
types of lights and electrical equipment and the proportion of each tenant's
Rentable Area to the Rentable Area of all tenants to which the common meter
relates. Upon receipt of the Landlord's statement of apportionment, the Tenant
shall promptly reimburse the Landlord for all amounts apportioned to the Tenant
by the Landlord provided that the Landlord may elect by notice to the Tenant to
estimate the amount which will be apportioned to the Tenant and require the
Tenant to pay that amount in monthly installments in advance simultaneously with
the Tenant's payments of Basic Rent. Notwithstanding the foregoing, and whether
the Leased Premises are separately metered or not, the Landlord may purchase in
bulk from the utility supplier the aggregate utility requirements of the Project
at the applicable rates determined by a single meter on the Project and may, in
billing the Tenant for its share of such utility, apply a scale of rates not
greater than the current scale of rates at which the Tenant would from time to
time be purchasing the whole of its utilities required and consumed in respect
of the Leased Premises if the Tenant were purchasing directly from the utility
supplier. The Tenant shall upon the Landlord's request install a separate
utility meter or meters in the Leased Premises at the Tenant's expense.

In addition to the payments to the Landlord required by this Article 7.00, the
Tenant shall pay all rates, charges, costs and expenses as may be assessed or
levied by any supplier of utilities to the Tenant other than those supplied by
the Landlord.

7.02 LIGHTS - In addition to the payment of Tenant's Occupancy Costs and
notwithstanding Sections 6.01 and 6.02, except to the extent the same is
included in Operating Costs, the Tenant shall pay to the Landlord monthly in
advance, with its payments of Basic Rent, a reasonable amount as determined by
the Landlord in respect of replacement of building standard fluorescent tubes,
light bulbs and ballasts in the Leased Premises on a periodic basis or as
required from time to time and the costs of cleaning, maintaining and servicing
of the electrical light fixtures in the Leased Premises.

7.03 HEATING, VENTILATION AND AIR CONDITIONING - In addition to the payment of
Tenant's Occupancy Costs and notwithstanding Sections 6.01 and 6.02, the Tenant
shall be responsible for the cost of all heating, ventilation and air
conditioning required in the Leased Premises or any part thereof in excess of
that required to be provided by the Landlord under Section 6.02(d). If at any
time during the Term the Landlord shall determine that the cost of the heating,
ventilation and air conditioning required in the Leased Premises or any part
thereof is in excess of that normally required in other parts of the Building
which are used for normal office purposes, the Landlord may deliver to the
Tenant a statement in writing setting out the cost of the excess and upon
receipt of the statement from time to

                                                                         Page 13
<PAGE>

time the Tenant shall promptly reimburse the Landlord for the amount shown in
the statement as attributable to the Leased Premises.

7.04 ALTERATIONS BY TENANT* - The Tenant may from time to time at its own
expense make changes, additions and improvements to the Leased Premises to
better adapt the same to its business, provided that any change, addition or
improvement shall:

(a)   comply with the requirements of the Landlord's insurers and any
      governmental or municipal authority having jurisdiction;

(b)   notwithstanding anything set out in this Lease to the contrary, the
      Landlord acknowledges and agrees that the Tenant shall not be liable for
      any Pollutants, in on, over, under or emanating from the Project prior to
      the date which is the earliest of the following: (a) the date on which the
      Tenant takes occupancy of the Leased Premises under this Lease; or (b) the
      date on which the Tenant took occupancy of the Leased Premises under any
      prior lease of the Leased Premises; or (c) the date on which the Tenant
      took occupancy of any other premises in the Project under any other lease
      of such other premises in the Project; or (d) the Commencement Date of
      this Lease, provided the Tenant, its representatives, employees, agents,
      visitors or those authorized to be in the Leased Premises or the Project,
      invitees, contractors and all other persons for whom the Tenant is in law
      responsible in no way contributed to the existence, damage, disturbance or
      release in any way of any such Pollutants in, on, over, under or emanating
      from the Product.

(c)   shall be made only after detailed plans and specifications therefor have
      been submitted to the Landlord and received the prior written approval of
      the Landlord, all at the expense of the Tenant, and should the Landlord
      provide its written approval, such approval shall not be deemed to mean
      that the proposed changes, additions or improvements comply with any
      existing or future municipal by-laws or any other applicable laws,
      by-laws, codes or requirements. All costs incurred with respect to such
      approval shall be at the expense of the Tenant. Any changes, additions
      and/or improvements affecting the Building's electrical, mechanical and/or
      structural components shall only be performed by contractors selected by
      the Landlord (the "Landlord's Contractors"). A list of the Landlord's
      Contractors is available upon request;

(d)   equal or exceed the then current standard for the Building;

(e)   be carried out in a good and workmanlike manner and subject to Subsection
      7.04(c), only by Persons selected by the Tenant and approved in writing by
      the Landlord who shall, if required by the Landlord, deliver to the
      Landlord before commencement of the work, performance and payment bonds as
      well as proof of workers' compensation and public liability and property
      damage insurance coverage, with the Landlord and the Landlord's agent and
      nominee (if any) named as additional insureds, in amounts, with companies
      and in a form reasonably satisfactory to the Landlord, which shall remain
      in effect during the entire period in which the work will be carried out;
      and

(f)   be made only after the Tenant has provided to the Landlord evidence of all
      requisite permits and licenses and any other information reasonably
      required by the Landlord.

Upon completion of such change, addition or improvement, the Tenant shall
provide to the Landlord as-built drawings and/or a CAD disk of same in a format
useable by the Landlord, together with evidence satisfactory to the Landlord of
a final inspection of such change, addition or improvement (including inspection
of mechanical and electrical systems where applicable) by the authority which
issued the permit or license for same.

It is understood and agreed that the Landlord shall have no responsibility or
liability whatsoever with respect to any such work or attendant materials left
or installed in the Project and shall be reimbursed for any Outlays and for any
delays caused to the Landlord or its contractor(s) directly or indirectly as a
result thereof. The Tenant shall be solely responsible for the removal of any
and all construction refuse or debris resulting from such work with such removal
to occur only after normal business hours.

Any increase in Taxes or fire or casualty insurance premiums for the Project
attributable to such change, addition or improvement shall be borne by the
Tenant. The Tenant shall promptly repair at its own expense any damage to the
Leased Premises or the Project, including without limitation the property of
others, resulting from such changes, additions or improvements.

7.05 TENANT'S TRADE FIXTURES AND PERSONAL PROPERTY - The Tenant may install in
the Leased Premises its usual trade fixtures and personal property in a proper
manner; provided that no installation or repair shall interfere with or damage

the course of reconstruction, renovation or alteration of the Leased Premises by

      such work and following completion thereof.

If the Landlord or its agents shall determine that the work being done by the
Tenant is in breach of this Lease or fails to comply with the requirements of
this Lease in any respect, the Tenant shall forthwith remedy such breach or
failure to comply and shall desist from continuing the same. The Tenant shall,
at its own cost, make good any deficiency in such work and remedy any failure to
comply with the requirements of this Lease.

7.08 FAILURE TO MAINTAIN - If the Tenant fails to perform any obligation under
this Article 7.00, then on not less than 5 days' notice to the Tenant, the
Landlord may enter the Leased Premises and perform the obligation without
liability to the Tenant for any loss or damage thereby incurred. The Tenant
shall promptly after receiving the Landlord's invoice therefor reimburse the
Landlord for all costs incurred by the Landlord in performing the obligation
plus 20% of the costs for overhead and supervision.

7.09 LIENS - The Tenant shall:

                                                                         Page 15
<PAGE>

(a)   pay promptly when due all costs for work done or caused to be done or
      goods affixed by the Tenant in the Leased Premises which could result in
      any lien or encumbrance on the Landlord's interest in the Project or any
      part thereof, or the filing or registration of any security interest or
      notice thereof;

(b)   keep the title to the Project, including every part thereof and the
      Leasehold Improvements, free and clear of any lien, encumbrance or
      security interest or notice thereof; and

when due (except for Taxes payable directly to the taxing authority by the
Tenant under Subsection 8.02(c)) and subject to the provisions hereinafter
contained in this Article 8.00. Provided however, that the Landlord may defer
payment of any such Taxes or defer compliance with any statute, law, by-law,

      and Building and referred to herein as "Business Taxes".

The Tenant agrees to provide to the Landlord within 3 days of receipt thereof,

such other information as the Landlord may require.

8.03 TAX INCREASES ATTRIBUTABLE TO TENANT - If any Taxes in respect of the
Leased Premises or Project are greater than they otherwise would have been by

Landlord may in its absolute discretion allocate such amount among tenants of
the Building and the amount allocated to the Tenant shall form part of Tenant's
Occupancy Costs.

If there are not separate assessments of Property Taxes for the Leased Premises
or the Building, the Landlord shall allocate Property Taxes to the Building and

limitation, to the various uses and values of the subject Project Components,
any separate assessments that may have been rendered by the taxing authority and
any assessment principles known or prescribed by any lawful taxing authority.

8.06 RIGHT TO CONTEST - Each of the Landlord and the Tenant (provided the Tenant
is legally entitled to do so) shall have the right to contest in good faith the
validity or amount of any Taxes which, in the case of the Landlord, the Landlord
is responsible to pay under this Article 8.00 and which, in the case of the
Tenant, the Tenant is responsible to pay under Section 8.02 and for which it is
separately assessed. Notwithstanding anything to the contrary herein, the Tenant
may, upon prior written notice to the Landlord, defer payment of any amount
payable by it pursuant to Section 8.02 for which it is separately assessed, to
the extent permitted by law; provided that no contest by the Tenant shall
involve the possibility of forfeiture, sale or disturbance of the Landlord's
interest in the Leased Premises or the imposition of any penalty or interest,
charge or lien and that, upon the final determination of any contest by the
Tenant, the Tenant shall immediately pay and satisfy the amount found to be due,
together with any costs, penalties and interest. If, as a result of any contest
by the Tenant, any tax, rate, levy, assessment, fee or other charge is

appeal any assessment therefor except as follows:

      like instrument and obtain the Landlord's consent thereto, which consent
      shall not be unreasonably withheld, before filing the same;

      requires;

(c)   the Tenant shall promptly and diligently prosecute the contest or appeal
      at its sole expense; and

agent falls to do so) the cost of premiums to the Building and any other of the
Project Components (and such other properties as may be appropriate), covered by
the insurance policy on an equitable basis having regard, without limitation, to
the various uses and values of the subject Project Components and any other
properties so included and the recommendation of the Landlord's insurance

      clause;

                                                                         Page 18

      separately insured; such insurance shall include cross liability and
      severability of interest clauses;

(c)   boiler and machinery insurance, if applicable, including repair or

      Premises by or on behalf of the Tenant or otherwise constituting Leasehold
      improvements;

(d)   plate glass insurance on all internal and external glass within or

      coverage with a period of indemnity of not less than 12 months and subject

      Landlord may from time to time reasonably require.

The Tenant acknowledges and agrees that it shall be solely responsible for
insuring the Leasehold Improvements, its equipment and stock and any other

to the Building or not.

The insurance policies referred to in this Section shall be subject to such
higher limits as the Tenant, or the Landlord acting reasonably, or any mortgagee
of the Landlord's interest in the Project may require from time to time. The
policies of insurance referred to in Subsections 9.02(a), (b), (c), (d), (e) and
(f) shall contain a waiver of the insurer's right of subrogation as against the
Landlord. The Tenant hereby waives its right of recovery against the Landlord,
its employees and those for whom the Landlord is in law responsible with respect
to occurrences required to be insured against by the Tenant hereunder. Any and
all deductibles in the Tenant's insurance policies shall be borne solely by the
Tenant and shall not be recovered or attempted to be recovered from the
Landlord. In addition, all such policies shall be noncontributing with, and will
apply only as primary and not excess to, any insurance proceeds available to the
Landlord.

The Tenant shall provide to the Landlord at the commencement of the Term and at
least 30 days prior to the renewal of all Insurance referred to in this Section
9.02, and promptly at any time upon request, a certificate of insurance
evidencing the insurance coverage maintained by the Tenant in accordance with
this Section 9.02. The delivery to the Landlord of a certificate of Insurance or
any review thereof by or on behalf of the Landlord shall not limit the
obligation of the Tenant to provide and maintain insurance pursuant to this
Section 9.02 or derogate from the Landlord's rights if the Tenant shall fail to
fully insure.

All policies shall provide that the insurance shall not be cancelled or changed
to the prejudice of the Landlord without at least 30 days' prior written notice
given by the Insurer to the Landlord. All policies of insurance shall be placed
with a company licensed to sell commercial insurance in Canada.

The Tenant acknowledges and agrees that, if it fails to obtain and maintain in
force any of the insurances set out in this Section 9.02, then the Tenant shall
indemnify the Landlord in respect of any losses arising therefrom.

9.03 PLACEMENT OF TENANT'S INSURANCE BY LANDLORD - If the Tenant fails to place
or maintain all or any of the insurance coverage referred to in Section 9.02,
the Landlord may, at its option, place all or any part of such insurance in the
name of or on behalf of the Tenant and the Tenant shall pay to the Landlord upon
demand all costs incurred by

                                                                         Page 19

for such insurance together with the Landlord's administrative fee of 15% of
such premium.

9.04 LIMITATION OF LANDLORD'S LIABILITY - The Landlord, its agents and employees
and any Person for whom it is in law responsible shall not be liable under any

DELETED AND INITIALED AND THE TERMS AND CONDITIONS STATED ON RIDER 1 WILL GOVERN
THE RELATIONSHIP BETWEEN THE LANDLORD AND THE TENANT WITH RESPECT TO
ENVIRONMENTAL ISSUES.]

                     ARTICLE 10.00 - DAMAGE AND DESTRUCTION

10.01 LIMITED DAMAGE TO LEASED PREMISES, ACCESS OR SERVICES - If during the
Term, the Leased Premises or any part thereof, or other portions of the Building
providing access or Services essential to the Leased Premises, shall be
destroyed or damaged by any hazard against which the Landlord is obligated to
insure pursuant to Section 9.01, the Landlord, if permitted by law so to do,
shall proceed with reasonable diligence to rebuild and restore or repair the
Leased Premises or comparable premises or such access routes or Service systems,
as the case may be, in conformance with current laws to the extent of insurance
proceeds received. The covenants of the Tenant to repair shall not include any
repairs of damage required to be made by the Landlord under this Section 10.01.
Rent payable by the Tenant shall abate from the date of such damage or
destruction to the date of substantial completion of the Landlord's work as
determined by the Landlord's architect or engineer or restoration of access or
Services, as the case may be. If less than all of the Leased Premises is
destroyed or damaged as contemplated in this Section 10.01, Rent payable by the
Tenant shall abate from the date of such damage or destruction to the date of
substantial completion of the Landlord's work in the same proportion as the
Rentable Area of the Leased Premises so damaged or destroyed is of the total
Rentable Area of the Leased Premises.

10.02 MAJOR DAMAGE TO LEASED PREMISES - Notwithstanding anything contained in
this Lease to the contrary, if the Leased Premises shall be damaged or destroyed
by any hazard against which the Landlord is obligated to insure under this
Lease; and if in the opinion of the Landlord's architect or engineer, given
within 30 business days of the happening of said damage or destruction, said
damage or destruction is to the extent that the Leased Premises shall be
incapable of being rebuilt or repaired or restored with reasonable diligence
within 6 months after the occurrence of such damage or destruction, then the
Landlord may, at its option, terminate this Lease by notice in writing to the
Tenant given within 15 days after the giving of the opinion by the Landlord's
architect or engineer. If such notice is given by the Landlord under this
Section 10.02, then this Lease shall terminate on the date of such notice and
the Tenant shall immediately surrender the Leased Premises and all interest
therein to the Landlord and Rent shall be apportioned and shall be payable by
the Tenant only to the date of such damage or destruction and the Landlord may
re-enter and repossess the Leased Premises.

The Tenant agrees that in the event of damage or destruction to the Leased
Premises covered by insurance required to be taken out by the Tenant pursuant to
Section 9.02 or otherwise, the Tenant shall use the proceeds of such insurance
for the purpose of repairing or restoring such damage or destruction. In the
event of damage to or destruction of the Project or the Building entitling the
Landlord to terminate the Lease pursuant to this Article 10.00, then, if the
Leased Premises have been damaged or destroyed, the Tenant shall pay to the
Landlord all of its insurance proceeds relating to any Leasehold Improvements in
the Leased Premises which the Tenant was required to insure and, if the Leased
Premises have not been damaged or destroyed, the Tenant shall deliver to the
Landlord, in accordance with the provisions of this Lease, all Leasehold
Improvements and the Leased Premises.

10.03 DAMAGE TO BUILDING - Notwithstanding that the Leased Premises may not be
affected, if in the reasonable opinion or determination of the Landlord or the
Landlord's architect or engineer, rendered within 30 business days of

                                                                         Page 21
<PAGE>

the happening of damage or destruction, the Building shall be damaged or
destroyed to the extent that any one or more of the following conditions exist:

(a)   in the reasonable opinion of the Landlord the Building must be totally or
      partially demolished, whether or not to be reconstructed in whole or in
      part; or

(b)   in the reasonable opinion of the Landlord's architect or engineer the
      Building shall be incapable of being rebuilt or repaired or restored with
      reasonable diligence within 6 months after the occurrence of such damage
      or destruction; or

(c)   any tenant of the Building which, in the Landlord's absolute discretion,
      is a major tenant of the Building becomes entitled to terminate its lease
      as a result of such damage or destruction; or

(d)   more then 35% of the Rentable Area of the Building is damaged or destroyed
      as reasonably determined by the Landlord's architect or engineer; or

(e)   any or all of the heating, ventilating, air conditioning, electrical,
      mechanical or elevator systems in the Building are damaged or destroyed as
      reasonably determined by the Landlord's architect or engineer;

then the Landlord may at its sole option terminate this Lease by notice in
writing to the Tenant given within 15 days after the rendering of such opinion
or determination. If notice is given by the Landlord under this Section 10.03,
then this Lease shall terminate from the date of such notice and the Tenant
shall immediately surrender the Leased Premises and all interest therein to the
Landlord and Rent shall be apportioned and shall be payable by the Tenant only
to the date of such notice and the Landlord may thereafter re-enter and
repossess the Leased Premises. If the Building is damaged to the extent
described in this Section 10.03 and the Landlord does not terminate this Lease,
the Landlord will rebuild or repair the Building to base building standards, but
the rebuilt or repaired Building may be different in configuration and design
from that comprising the Project prior to the damage or destruction.

10.04 NO ABATEMENT - Except as specifically provided in this Article 10.00,
there shall be no abatement of Rent and the Landlord shall have no liability to
the Tenant by reason of any injury to, loss of or interference with the Tenant's
business or property arising directly or indirectly from fire or other casualty,
howsoever caused, or from the making of any repairs resulting therefrom or to
any portion of the Building or the Leased Premises.

10.05 NOTIFY LANDLORD - The Tenant shall immediately notify the Landlord or its
representative in the Project of any accident or detect in the Project, the
Leased Premises or any systems thereof and, as well, of any matter or condition
which may cause injury or damage to the Project or any person or property
located therein.

10.06 EXPROPRIATION - If at any time during the Term the whole or any pert of
the Leased Premises shall be taken by any lawful power or authority by the right
of Expropriation, the Landlord may, at its option, give notice to the Tenant of
termination of this Lease either in its entirety or only insofar as it affects
the part of the Leased Premises taken by the lawful power or authority by right
of Expropriation, on the date when the Tenant or the Landlord is required to
yield up possession thereof to the Expropriating authority. Upon such
termination, or upon termination by operation of law, as the case may be, the
Tenant shall immediately surrender the Leased Premises or the part of the Leased
Premises taken by the Expropriating authority, as the case may be, and all its
interest therein, and Rent shall abate and be apportioned to the date of
termination and the Tenant shall forthwith pay to the Landlord the apportioned
Rent and all other amounts which may be due to the Landlord up to the date of
termination. The Tenant shall have no claim upon the Landlord for the value of
its property or the unexpired Term, but the parties shall each be entitled
separately to advance their claims for compensation for the loss of their
respective interests in the Leased Premises so taken, and the parties shall each
be entitled to receive and retain such compensation as may be awarded to each
respectively. However, to the extent that a part of the Project other than the
Leased Premises is Expropriated the full proceeds paid or awarded therefor will
belong solely to the Landlord and the Tenant will assign to the Landlord any
rights it might have or acquire in respect of such proceeds or awards and will
execute those documents that the Landlord reasonably requires in order to give
effect to this intention.

                                                                         Page 22

Where used in this Section 10.06 "Expropriation" means expropriated by a
governmental or municipal authority, or transferred, conveyed or dedicated in
contemplation of a threatened expropriation and "Expropriated" and
"Expropriating" have corresponding meanings.

                            ARTICLE 11.00 - DEFAULT

11.01 INTEREST - The Tenant shall pay monthly to the Landlord interest at a rate
per annum equal to the lesser of the Prime Rate plus 5% and the maximum rate
permitted by applicable law upon all Rent required to be paid hereunder from the
due date for payment thereof until the same is fully paid and satisfied.

11.02 COSTS OF ENFORCEMENT - The Tenant shall indemnify the Landlord against all
costs and charges (including legal fees one solicitor and client basis)
reasonably incurred either during or after the Term in enforcing payment of Rent
hereunder and in obtaining possession of the Leased Premises after default of
the Tenant or upon expiration or earlier termination of this Lease or in
enforcing any covenant, proviso or agreement of the Tenant herein contained or
in determining the Landlord's rights or the Tenant's obligations under this
Lease or both. All such costs and charges shall be paid by the Tenant to the
Landlord forthwith upon demand.

11.03 PERFORMANCE OF TENANT'S OBLIGATIONS - All covenants and agreements to be
performed by the Tenant under any of the terms of this Lease shall be performed
by the Tenant, at the Tenant's sole cost and expense, and without any abatement
of Rent. If the Tenant fails to perform any act to be performed by it hereunder
then, in the event of an emergency, either real or perceived, or if the failure
continues for 10 days following notice thereof, the Landlord may (but shall not
be obligated to) perform the act without waiving or releasing the Tenant from
any of its obligations relative thereto; but having commenced to do so may cease
to do so without completing performance thereof. All sums paid and costs
incurred by the Landlord in so performing the act, plus 20% of the cost for
overhead and supervision together with interest thereon at the rate set out in
Section 11.01 from the date payment was made or such cost was incurred by the
Landlord, shall be payable by the Tenant to the Landlord on demand.

(a)   all or any part of the Rent hereby reserved is not paid when due; or

(b)   the Term or any goods, merchandise, stock in trade, chattels or equipment
      of the Tenant or any Indemnifier is or are seized or taken or exigible in

(c)   the Tenant or any Indemnifier or any Person bound to perform the
      obligations of the Tenant in this Lease either as guarantor or indemnifier
      or as one of the parties constituting the Tenant takes any steps in
      furtherance of or suffers any order to be made for its winding-up or other
      termination of its corporate existence or becomes insolvent or commits an
      act of bankruptcy or becomes bankrupt or takes the benefit of any statute
      that may be in force for bankrupt or insolvent debtors or becomes involved
      in voluntary or involuntary winding-up proceedings or if a receiver or
      receiver/manager shall be appointed for all or any part of the business,
      property, affairs or revenues of the Tenant or such indemnifier or Person;
      or

(d)   the Tenant makes a bulk sale of its goods or moves or commences, attempts
      or threatens to move its goods, chattels and equipment, or any of them,
      out of the Leased Premises (other than in the normal course of its
      business) or ceases to conduct business in the Leased Premises; or

(e)   the Tenant fails to move into or take possession of the Leased Premises or
      vacates or abandons the Leased Premises in whole or in part or fails to
      actively carry on business therein; or

(f)   the Tenant or any indemnifier or any Person bound to perform the
      obligations of the Tenant pursuant to this Lease either as guarantor or

      observe, perform and keep each and every covenant, agreement, provision,
      stipulation and condition herein contained to be observed, performed and
      kept by the Tenant or the indemnifier (other than payment of Rent) and

                                                                         Page 23
<PAGE>

      persists in the failure after 10 days' notice by the Landlord requiring
      the Tenant to remedy, correct, desist or comply (or if any breach would
      reasonably require more than 10 days to rectify, unless the Tenant
      commences rectification within the 10 day notice period and thereafter
      promptly, effectively and continuously proceeds with the rectification of
      the breach); or

(g)   any Transfer occurs except as permitted by and in accordance with Article
      12.00; or

(h)   any Pollutants are present in the Leased Premises without the prior
      written consent of the Landlord or otherwise than in compliance with all
      terms and conditions imposed by the Landlord in giving its consent
      thereto; or

(i)   a report or statement required from the Tenant under this Lease is false
      or misleading except if it results from an innocent clerical error as
      determined by the Landlord; or

(k)   the Tenant fails to observe and perform the rules and regulations; or

(l)   the use of the Leased Premises is not in accordance with that set out in
      Item 9 of the Term Sheet;

then the Landlord shall be entitled to any or all of those remedies set out in
Section 11.05. Each of the foregoing circumstances constitutes an "Event of
Default" for the purposes of this Lease.

11.05 REMEDIES ON DEFAULT - Upon the happening of an Event of Default the
Landlord may at its option, and in addition to and without prejudice to all
rights and remedies of the Landlord available to it either by any other
provision of this Lease or by statute or the general law exercise any one or
more of the following remedies:

(a)   be entitled to the full amount of the current month's and the next ensuing
      3 months' installments of Rent which shall immediately become due and
      payable and the Landlord may immediately distrain for the same, together
      with any arrears then unpaid; or

(b)   without notice or any form of legal process, forthwith re-let or sublet
      the Leased Premises or any part or parts thereof for whatever term or
      terms and at whatever rent and upon whatever other terms, covenants and
      conditions the Landlord considers advisable including, without limitation,
      the payment or granting of inducements all on behalf of the Tenant: and on
      each such re-letting or subletting the rent received by the Landlord
      therefrom will be applied first to reimburse the Landlord for any such
      inducements and for any expenses, capital or otherwise, incurred by the
      Landlord in making the Leased Premises ready for re-letting or subletting;
      and secondly to the payment of any costs end expenses of re-letting or
      subletting including brokerage fees and legal fees on a solicitor and
      client basis; and third to the payment of Rent; and the residue, if any,
      will be held by the Landlord and applied to payment of Rent as it becomes
      due and payable. If rent received from re-letting or subletting during any
      month is less than Rent to be paid during that month hereunder, the Tenant
      will pay the deficiency which will be calculated and paid monthly on or
      before the first day of every month; and no re-letting or subletting of
      the Leased Premises by the Landlord or entry by the Landlord or its agents
      upon the Leased Premises for the purpose of re-letting or subletting or
      other act of the Landlord relating thereto including, without limitation,
      changing or permitting a subtenant to change locks, will be construed as
      an election on its part to terminate this Lease unless a written notice of
      termination is given to the Tenant; and if the Landlord elects to re-let
      or sublet the Leased Premises without terminating, it may afterwards elect
      to terminate this Lease at any time by reason of any Event of Default then
      existing; or

(c)   seize and sell such goods, chattels and equipment of the Tenant as are in
      the Leased Premises and the Landlord may, but shall not be obligated to,
      apply the proceeds thereof to all Rent to which the Landlord is then
      entitled under this Lease. Any such sale may be effected by public
      auction, private sale or otherwise, and either in bulk or by individual
      item, or partly by one means and partly by another, all as the Landlord in
      its sole discretion may decide; or

                                                                         Page 24
<PAGE>

(d)   terminate this Lease by leaving upon the Leased Premises notice in writing
      of the termination, and such termination shall be without prejudice to the
      Landlord's right to damages, it being agreed that the Tenant shall pay to
      the Landlord on demand as damages the loss of income of the Landlord to be
      derived from this Lease and the Leased Premises for the unexpired portion
      of the Term had it not been terminated; or

(e)   re-enter into and upon the Leased Premises or any part thereof in the name
      of the whole and repossess and enjoy the same as of the Landlord's former
      estate, anything herein contained to the contrary notwithstanding;

and the Tenant shall pay to the Landlord forthwith upon demand all expenses of
the Landlord in reentering, terminating, re-letting, collecting sums due or
payable by the Tenant or realizing upon assets seized or otherwise exercising
its rights and remedies under this Section 11.05 including tenant inducements,
leasing commissions, legal fees on a solicitor and client basis and all
disbursements and the expense of keeping the Leased Premises in good order,
repairing the same and preparing the same for re-letting.

In addition, and without limiting the generality of the foregoing provisions of
this Section 11.05, upon the happening of an Event of Default, and whether or
not this Lease is terminated in accordance with such provisions: (i) the
Landlord shall have no further liability to pay to the Tenant or any third party
any amount on account or in respect of a refund of any Security Deposit, prepaid
Rent or prepaid Taxes or any tenant inducement, leasehold improvement allowance,
lease takeover or lease subsidy or any other concession or inducement otherwise
provided to the Tenant under or with respect to this Lease, and any Rent free
period otherwise provided to the Tenant hereunder shall be null and void and of
no further force or effect and Rent shall be payable in full hereunder without
regard to any such Rent free period; and (ii) any cash allowance, inducement
payment, and the value of any other benefit paid to or conferred on the Tenant
by or on behalf of the Landlord in connection with the Leased Premises or this
Lease shall be recoverable in full as additional Rent and shall be payable to
the Landlord on demand.

11.06 AVAILABILITY OF REMEDIES - The Landlord may from time to time resort to
any or all of the rights and remedies available to it upon the occurrence of an
Event of Default either by any provision of this Lease or by statute or the
general law, all of which rights and remedies are intended to be cumulative and
not alternative, and the express provisions herein as to certain rights and
remedies are not to be interpreted as excluding any other or additional rights
or remedies available to the Landlord by statute or the general law.

11.07 WAIVER - If the Landlord shall overlook, excuse, condone or suffer any
default, breach or nonobservance by the Tenant of any obligation hereunder, this
shall not operate as a waiver of the obligation in respect of any continuing or
subsequent default, breach or non-observance and no such waiver shall be implied
but shall only be effective if expressed in writing.

The Landlord's acceptance of Rent after a default is not a waiver of any
preceding default under this Lease even if the Landlord knows of the preceding
default at the time of acceptance of the Rent. No term, covenant or condition of
this Lease shall be considered to have been waived by the Landlord or the Tenant
unless the waiver is in writing. The Tenant waives any statutory or other rights
in respect of abatement, set-off or compensation in its favour that may exist or
come into existence hereafter with respect to Rent.

11.08 WAIVER OF EXEMPTION AND REDEMPTION - Notwithstanding anything contained in
any statute now or hereafter in force limiting the right of distress, none of
the Tenant's goods or chattels in the Leased Premises at any time during the
Term shall be exempt from levy by distress for Rent in arrears and this
agreement of the Tenant in this Section may be pleaded as an estoppel against
the Tenant.

11.09 COMPANIES' CREDITORS ARRANGEMENT ACT - By virtue of its interest in this
Lease, the importance of the Tenant continuing to carry on business in the
Leased Premises in accordance with this Lease, end the Landlord's entitlement to
damages where this Lease is terminated by reason of an Event of Default, the
Landlord does and will (despite any changes in circumstances of the Tenant or
its business) constitute a separate class or category of creditor in any plan of
arrangement or other proposal submitted by or on behalf of the Tenant under the
Companies' Creditors Arrangement Act (Canada) or any similar legislation for
bankrupt or insolvent debtors.

                                                                         Page 25
<PAGE>

           ARTICLE 12.00 - ASSIGNMENT, SUBLETTING AND OTHER TRANSFERS

12.01 REQUEST FOR CONSENT - The Tenant shall not effect a Transfer of this Lease
or of all or part of the Leased Premises without the prior consent in writing of
the Landlord, which consent shall not, provided no Event of Default has
occurred, be unreasonably withheld. Provided that the Tenant shall, at the time
the Tenant shall request the consent of the Landlord, deliver to the Landlord
such information in writing (herein called the required information) as the
Landlord may reasonably require respecting the proposed Transferee including,
without limitation, the name, address, nature of business, financial
responsibility and standing of such proposed Transferee. Provided further that
after receiving such request, the Landlord shall have the right, at its option,
to terminate this Lease if the request relates to all of the Leased Premises or,
if the request relates to a portion of the Leased Premises only, to terminate
this Lease with respect to such portion, by giving, within 10 days after
receiving the required information, not less then 30 nor more than 60 days'
written notice of termination to the Tenant. In the event of such termination
the Rent and other payments required to be made by the Tenant hereunder shall be
adjusted to the date of termination and in the case of a partial termination,
Rent shall abate in the proportion that the area of the portion of the Leased
Premises for which this Lease is terminated bears to the area of the Leased
Premises and this Lease shall be deemed to be amended accordingly.

If the Landlord elects to terminate this Lease as to all or part of the Leased
Premises, the Tenant may by written notice (given within 10 days or such longer
time as the Landlord may consent to in writing after receipt of the Landlord's
notice of termination) notify the Landlord of the Tenant's intention to refrain
from the Transfer which gave rise to the Landlord's notice of termination or of
the Tenant's intention to accept such notice of termination. If the Tenant gives
such written notice to the Landlord within such time period that it intends to
refrain from such Transfer, then the Landlord's election to terminate this Lease
in whole or in part shall become null and void. Otherwise, the Landlord's
termination shall take effect on the date stipulated by the Landlord in its
notice of termination.

12.02 BASIS FOR CONSENT - Notwithstanding any statute or law and without
limiting the grounds upon which a consent may be refused, the Landlord will not
be deemed to be unreasonable in refusing consent when:

(a)   the giving of such consent would place the Landlord in breach of any other
      tenant's lease in the Project or the proposed use by the Transferee is not
      substantially the same as that of the Tenant;

(b)   such consent is requested for a mortgage, charge, debenture (secured by
      floating charge or otherwise) or other encumbrance of, or in respect of,
      this Lease or the Leased Premises or any part of them;

(c)   the Transferee, in the opinion of the Landlord; (i) does not have a
      history of successful business operation in the business to be conducted
      in the Leased Premises, (ii) does not have a good credit rating or a
      substantial net worth, or (iii) there is a history of default under other
      leases by the Transferee or by companies or partnerships that the
      Transferee was a principal shareholder of or a partner in at the time of
      the default;

(d)   the Transferee is an existing tenant in the Project or in any other
      project of the Landlord, or has been within 3 months prior to the proposed
      assignment or sublease taking affect;

(e)   the Landlord has other premises in the Project available for leasing to
      the Transferee;

(f)   in the case of a Transfer to a subtenant of less than the entire Leased
      Premises, if such would result in a congratulation which: (i) would
      require access to be provided through space leased or held for lease to
      another tenant or improvements to be made outside of the Leased Premises,
      or (ii) would, in the sole opinion of the Landlord, be unreasonable to
      attempt to re-lease to a third party;

(g)   the required information received from the Tenant or the Transferee is not
      sufficient in the Landlord's opinion to enable the Landlord to make a
      determination concerning the matters set out above; or

(h)   the use of the Leased Premises by the proposed Transferee, in the
      Landlord's opinion arrived at in good faith, could result in excessive use
      of the systems or Services in the Project, be inconsistent with the image
      and

                                                                         Page 26
<PAGE>

      standards of the Project or expose the occupants of the Project to risk of
      harm, damage or interference with their use and enjoyment thereof, or
      reduce the value of the Project.

The Landlord shall not be liable for any claims, actions, damages, liabilities,
losses or expenses of the Tenant or any proposed Transferee arising out of the
Landlord's unreasonably withholding its consent to any Transfer and the Tenant's
only recourse will be to bring an application for a declaration that the
Landlord must grant its consent to the Transfer.

In no event shall any Transfer to which the Landlord may have consented release
or relieve the Tenant or any Indemnifier from its obligations fully to perform
all the terms, covenants and conditions of this Lease, the indemnify Agreement
or any renewals or extensions of this Lease or the Term on its part to be
performed and, in any event, the Tenant shall be liable for the Landlord's costs
incurred in connection with the Tenant's request for consent as set out in
Subsection 12.03(g).

12.03 TERMS AND CONDITIONS RELATING TO CONSENTS - The following terms and
conditions apply in respect of a consent given by the Landlord to a Transfer:

(a)   the consent by the Landlord is not a waiver of the requirement for consent
      to subsequent Transfers, and no Transfer shall relieve the Tenant of its
      obligations under this Lease, unless specifically so provided in writing;

(b)   no acceptance by the Landlord of Rent or other payments by a Transferee
      is: (i) a waiver of the requirement for the Landlord to consent to the

      release of the Tenant or Indemnifier from its obligations under this Lease
      or any Indemnity Agreement;

      on the Landlord's standard form in respect of obligations to be performed
      after the Transfer by the Transferee;

(e)   the Transferee shall, when required by the Landlord, jointly and severally
      with the Tenant, enter into an agreement directly with the Landlord
      agreeing to be bound by this Lease as if the Transferee had originally
      executed this Lease as the Tenant, and the Tenant will not be released nor
      relieved from its obligations under this Lease including, without
      limitation, the obligation to pay Rent;

(f)   in the event that this Lease is disaffirmed, disclaimed or terminated by
      any trustee in bankruptcy of a Transferee, the original Tenant named in
      this Lease shall be deemed, upon notice by the Landlord given within 30
      days of such disaffirmation, disclaimer or termination to have entered
      into a lease with the Landlord containing the same terms and conditions as
      in this Lease, with the exception of the Term of such Lease which shall

      charge of at least $250.00 and the greater of: (i) a reasonable document
      preparation fee of at least $450.00, or (ii) those legal fees on a
      solicitor end client basis incurred by the Landlord will be paid to the
      Landlord by the Tenant on demand.

12.04 SUBSEQUENT TRANSFERS - The Landlord's consent to a Transfer shall not be
deemed to be consent to any subsequent Transfer, whether or not so stated.

12.05 PROFIT RENTS UPON TRANSFERS - In the event of any Transfer by the Tenant
by virtue of which the Tenant receives a rent in the form of cash, goods or
services from the Transferee which is greater than the Rent payable

                                                                         Page 27
<PAGE>

hereunder to the Landlord, the Tenant shall pay any such excess to the Landlord
in addition to all Rent payable under this Lease, and such excess rent shall be
deemed to be further Rent payable hereunder.

12.06 ADVERTISING - The Tenant shall not advertise the Leased Premises or any
part thereof as being available for leasing or this Lease as being available for
transfer in any medium and will not cause or permit any such advertisement,
unless the Landlord has permitted the Tenant to do so in writing and has given
written approval of the wording of such advertisement, which permission and
approval may be arbitrarily withheld.

Transferee and any new indemnifier of this Lease to grant a mortgage, charge and

Transfer.

The Tenant shall pay au costs associated with the granting and perfection of
mortgages, charges and security interests granted pursuant to this Lease upon

13.02 EFFECT OF TRANSFER - A sale, conveyance or assignment of the Project by
the Landlord shall operate to release the Landlord from liability from and after

period prior to the effective date, and the Tenant shall thereafter look solely
to the Landlord's successor in interest.

13.03 SUBORDINATION - Subject to Section 13.04, this Lease is and shall be
subject and subordinate in all respects to any and all mortgages (including
deeds of trust and mortgage) now or hereafter registered against title to the

                           ARTICLE 14.00 - SURRENDER

14.01 POSSESSION AND RESTORATION*

(1) Upon the expiration or other termination of the Term, the Tenant shall
immediately quit and surrender possession of the Leased Premises and all
Leasehold Improvements, in substantially the condition in which the Tenant is
required to maintain the Leased Premises, excepting only reasonable wear and
tear and damage covered by the Landlord's insurance under Section 9.01, and the
Tenant shall deliver to the Landlord the keys, mechanical or otherwise, and
combinations, if any, to the locks in the Leased Premises and entries thereto.
Notwithstanding the foregoing, the Landlord shall have the right, at its sole
option upon expiration or other termination of the Term, including any rights to
terminate as provided for in Schedule E, Sections V & VII, to require that the
Tenant remove or cause to be removed at the Tenant's cost all or any part of the
Leasehold Improvements in the Leased Premises installed by or on behalf of the
Tenant during a previous term or the Term of this Lease and to restore the
Leased Premises and other parts of the Project affected by the installation or
removal thereof subject to the specific provisions as provided for in Section
XII - Possession and Restoration herein. Any subsequent changes shall be subject
to the Landlord's written approval, with any requirement for removal to be
stipulated at the time of approval. In addition, the Landlord shall have the
right, at its sole option upon expiration or other termination of the Term, to
require that the Tenant remove or cause to be removed at the Tenant's cost all

affected by the installation or removal of the Wiring to their condition
existing prior to the installation of the Wiring (the "Wire Restoration Work").
Notwithstanding the foregoing, the Landlord may, at its sole option, perform the
Wire Restoration Work at the Tenant's sole cost and expense. Upon surrender, all
right, title, and interest of the Tenant in the Leased Premises and all
Leasehold Improvements located therein and in all Wiring shall cease.

Leased Premises and other parts of the Project affected by any installation or
removal of Leasehold Improvements to the condition required as outlined in

(the "restoration cost") the Tenant shall provide to the Landlord, by cash or
certified cheque, the restoration cost.

other termination of the Term or in the event of the abandonment of the Leased
Premises by the Tenant, all of the Leasehold Improvements, and the Tenant's

deemed conclusively to have been abandoned by the Tenant and may be
appropriated, sold, destroyed or otherwise disposed of by the Landlord

      of this Lease except any options thereby granted to the Tenant and except
      the Basic Rent which shall be twice the greater of: (i) the rate provided
      for herein for the final year of the Term; and (ii) the market rate as
      determined by the Landlord at the time of such overholding for similar
      premises, plus the sum of $200 daily and subject to such additional
      obligations and conditions as the Landlord may impose by notice to the
      Tenant; or

(b)   with the consent of the Landlord and agreement as to the Rent payable, the
      tenancy shall be month-to-month at the Rent agreed and otherwise on the

The Tenant shall promptly indemnify and hold harmless the Landlord from and
against all Claims against the Landlord as a result of the Tenant remaining in
possession of all or any part of the Leased Premises after the expiry of the
Term without the consent of the Landlord (including, without limitation, any
compensation to any new tenant or tenants which the Landlord may elect to pay
whether to offset the cost of overtime work or otherwise).

the then state of the accounts between the Landlord and the Tenant, the
existence or non-existence of defaults and any other matters pertaining to this
Lease in respect of which the Landlord shall request a certificate, and provide
such other information as may reasonably be required, including a copy of the
Tenant's most recent audited financial statements. The party or parties to whom
such certificates are addressed may rely upon them.

15.02 ENTIRE AGREEMENT - There is no promise, warranty, representation,
undertaking, covenant or understanding by or binding upon the Landlord except
such as are expressly set forth in this Lease and this Lease including the Term
Sheet and schedules hereto contains the entire agreement between the parties

15.03 NO REGISTRATION OF LEASE OR NOTICES - The Tenant shall not register or
apply to register this Lease or any notice of this Lease or any interest under
this Lease and waives any statutory obligation upon the Landlord to execute and

contravenes this Section. Notwithstanding the foregoing, the Landlord may elect
to require this Lease or notice of this Lease be registered.

part of the Building.

shall be delayed, hindered or prevented in or from the performance of any of its
covenants under this Lease by any cause not within the control of the delayed
party as determined by the Landlord acting reasonably (excluding lack of
finances of the delayed party), the performance of the covenant shall be excused
for the period during which performance is rendered impossible and the time for
performance thereof shall be extended accordingly, but this shall not excuse the
Tenant from the prompt payment of Rent or from the performance of any of its
other obligations under this Lease not related to such cause.

15.09 LIMITATION OF RECOURSE - The Tenant acknowledges that, notwithstanding any
other provision contained in this Lease, the obligations of and rights against

and enforced against, and recourse hereunder shall be had only after judgment
and only against, the right, title and interest of the Landlord from time to
time in, and the Landlord's revenue derived from, the Project. No obligation of
the Landlord hereunder or in respect hereof is personally binding upon, nor
shall any resort or recourse be had, judgment issued or execution or other
process levied against, the Landlord (except to the extent necessary for
enforcement under the first sentence of this Section 15.09 and only for that
purpose), or against any other assets or revenues of the Landlord. The only
remedy against the Landlord shall be an action for damages, except that if the
Tenant is of the opinion that any consent requested pursuant to Article 12.00
hereof has been wrongfully withheld, its remedies are as set out in Section
12.02.

Lease shall be given in writing and shall be sufficiently given if delivered or

specified in Item 1 of the Term Sheet and to the address set out in Item 1 of
the Term Sheet and if to the Tenant, so given to the Tenant personally (or to a
partner or officer of the Tenant if the Tenant is a firm or corporation) at the
address specified in item 2 of the Term Sheet or left at the Leased Premises
(whether or not the Tenant has departed from, vacated or abandoned the same).
Any notice shall be deemed to have been received on the business day following
the date of delivery or sending. The Landlord or the Tenant may from time to
time by notice in writing to the other designate another address or addresses in
Canada as the address to which notices are to be sent.

Notwithstanding the provision of any statute or law relating thereto, service by
means of electronic mail of any notice(s) required to be given in writing by
either party hereto pursuant to the Lease shall not constitute good and
effective service.

Tenant hereunder, notice given as herein provided to any one of the Persons
constituting the Tenant or so bound shall be deemed to be notice simultaneously
to all Persons constituting the Tenant and to all Persons so bound. Any notice
given to the Indemnifier or the Tenant shall be deemed to have been given
simultaneously to the other of them and to all Persons bound by their
obligations hereunder.

behalf of the Landlord in any manner provided for herein.

15.12 RELATIONSHIP OF PARTIES - Nothing contained in this Lease shall create any

described in Schedule G attached hereto and forming part hereof and all goods
(including inventory), trade fixtures and other personal property of the Tenant
located from time to time on the Leased Premises and any Leasehold Improvements
which the Tenant effects on or in respect of the Leased Premises (collectively
the "Collateral") . The Tenant may, however prior to the occurrence of an Event
of Default, sell or dispose of its inventory to its customers in the ordinary
course of business, in accordance with the terms and conditions of this Lease,
without the consent of the Landlord. The Tenant will promptly execute additional
documents and will provide additional information required by the Landlord from
time to time in connection with the Security Interest. The Tenant authorizes the
Landlord to file a financing statement and any other form of document required
in connection with the Security Interest to perfect, protect or preserve its
Security Interest. The Landlord's Security interest is in addition to and not in
lieu of its right of distress.

(2) The Landlord may enforce its Security Interest upon the occurrence of an
Event of Default in the manner outlined in Schedule G attached hereto and
forming part hereof or in any other manner available at law or in equity.

receive a copy of any financing statement, financing change statement or
verification statement relating to the Security Interest.

(5) The Landlord and the Tenant acknowledge that they have not agreed to

existing Collateral, and that the Security Interest shall attach to after
acquired Collateral as soon as the Debtor has rights in such Collateral.

15.26 SURVIVAL OF COVENANTS AND INDEMNITIES - All obligations of the Tenant
which arise during the Term pursuant to this Lease and which have not been
satisfied at the end of the Term and all indemnities of the Tenant contained in
this Lease shall survive the expiration or other termination of this Lease.

15.27 EXCULPATORY PROVISIONS - In all provisions of this Lease containing a
release, indemnity or other exculpatory language in favour of the Landlord,
reference to the Landlord includes reference also to the Landlord's agents and
nominee (if any) and any Person for whom it is in law responsible and the
directors, officers and employees of the Landlord, its agents and nominee (if
any) and any Person for whom it is in law responsible and its agents while

and for the benefit of the Released Persons solely to the extent necessary for

perform the covenants set out in such provision, the Tenant shall perform such
covenants unless the Tenant is otherwise directed by way of written notice from
the Landlord.

15.30 RADIATION - Only if the Landlord believes on reasonable grounds that
radiation is or has been used or created by the Tenant or any Person permitted
by the Tenant to be in the Leased Premises shall this Section 15.30 apply to the
Tenant.

The Tenant agrees, if so requested by the Landlord, to conduct at its own
expense a survey by an accredited firm of consultants acceptable to the Landlord
to determine the level of radiation in the Leased Premises, and if such levels
are in excess of those allowable under Environmental Laws and set by the
applicable regulatory authorities governing radiation, the Tenant agrees, at its
own cost and expense and on terms and conditions approved by the Landlord, to
reduce the level of radiation to a level allowable under Environmental Laws and
set by such applicable regulatory authorities.

15.31 MERGER - The voluntary or other surrender of this Lease by the Tenant or
the sublease of space by the Tenant to the Landlord or the cancellation of this
Lease by mutual agreement of the Tenant and the Landlord shall not operate as a
merger but shall, at the Landlord's option, terminate all or any subleases and
subtenancies or operate as an assignment to the Landlord of all or any subleases
or subtenancies. The Landlord's options hereunder shall be exercised by notice
to the Tenant and all known subtenants in the Leased Premises or any part
thereof.

15.32 DIVISION OF PROJECT

(1) The Landlord shall be entitled to sever the Land into separate parcels or to
consolidate the Land with other parcels and, after completion of such severance
or consolidation, the definitions of "Land" and "Project" shall be read to
correspond to such change. The separate parcels of the Land on severance may be
owned by or may be treated as if they were owned by separate entities other than
the Landlord. The Landlord may in its discretion create and grant rights and
easements among separate parcels or Project Components and may register same as
encumbrances.

(2) The Tenant acknowledges and agrees that if the Land is severed into 2 or
more separate parcels or consolidated into fewer parcels, the Tenant will
register any caveat indicating its interest in this Lease and the Leased
Premises against only the parcel(s) of the Land which is or are directly
affected by the Tenant's interest in this Lease and the Leased Premises as
directed by the Landlord and, if the Land is severed subsequent to the
registration of such caveat, the Tenant shall, at the Landlord's request, cause
to be registered a partial discharge of such caveat against the parcels of Land
not so directly affected by the Tenant's interest in this Lease and the Leased
Premises. If the Tenant fails to cause such partial discharge to be registered
within 15 days of a written request from the Landlord, the Landlord may take
such steps as it considers necessary to cause such caveat to be partially
discharged and the Tenant shall pay the Landlord for all Outlays within 10 days
of receipt of an invoice therefor.

(3)   (a)   From time to time the Landlord may, if, in the opinion of the
            Landlord, more efficient or economical operation of the Project or
            more equitable distribution of Operating Costs will result,
            establish Project Components (of which the Building shall be one)
            and divide, apportion and allocate Operating Costs among such
            Project Components.

      (b)   In any such division, apportionment and allocation of Operating
            Costs, the Landlord shall charge any item which relates exclusively
            to one of the Project Components directly to that Project Component
            only, and, in respect of items which do not exclusively relate to
            any single Project Component, the Landlord shall divide, apportion
            and allocate same to all Project Components affected thereby on an
            equitable basis having regard, without limitation, to the various
            uses and values of the subject Project Components, to prudent
            practices of property management, to the provisions of this Lease
            and to generally accepted accounting and engineering principles for
            the commercial real estate industry. The aggregate so directly
            charged or divided, apportioned and allocated to the Building is
            herein called the "Operating Costs for the Building".

                                                                         Page 34

<PAGE>

      (c)   If such treatment would result in a more equitable and compatible
            recognition of the cost of their respective usage, the Landlord may
            similarly, mutatis mutandis, charge, divide, apportion and allocate
            Operating Costs or Operating Costs for the Building among office,
            retail and other differing elements of the Building.

                                                                         Page 35

(vv)  if and whenever pursuant to Section 15.32 of the Lease, the Landlord shall
      have established and designated Project Components, in respect of
      Operating Costs which pertain only to a Project Component, the denominator
      aforesaid shall be the total Rentable Area of such areas as comprise that
      Project Component;

(ww)  if and whenever the Building shall have been established and designated as
      a Project Component, "Operating Costs for the Building" shall have the
      meaning ascribed in Section 15.32 and subsection (a) above shall govern
      apportionment thereof;

(xx)  in calculating Operating Costs for the Building for any Fiscal Year, if
      and while less than 95% of the Building is occupied by tenants, then the
      amount of Operating Costs shall be deemed for purposes of this Schedule to
      be increased to an amount equal to Operating Costs which normally would be
      expected to have been incurred had occupancy of the Building been 95%
      during period(s) when vacancies existed, to the intent that, after
      allowing for a periodic vacancy factor of 5%, the cost of Services
      actually provided by the Landlord to the Leased Premises will be recovered
      by the Landlord from the Tenant, while the Landlord will absorb the costs
      incurred in or attributable to rentable areas which are not occupied,
