         perform any of the terms, covenants and conditions of this Lease to be
         kept, observed and performed by the Tenant, then, the Landlord, at its
         option, may, in addition to any and all other rights and remedies
         provided for in this Lease or by law, appropriate and apply the balance
         of the Deposit (the "BALANCE") or so much thereof as if necessary to
         compensate the Landlord for loss or damage sustained or suffered by the
         Landlord due to such breach on the part of the Tenant. If the Balance
         or any portion thereof is appropriated and applied by the Landlord for
         the payment of overdue Rent or Additional Rent, then the Tenant shall,
         forthwith after demand by the Landlord, remit to the Landlord a
         sufficient amount in cash to restore the Balance to the original sum
         deposited and the Tenant's failure to do so forthwith after receipt of
         such demand constitutes a breach of this Lease.

4.4      The Landlord shall deliver the Balance to any purchaser of the
         Landlord's interest in the Leased Premises and the Development if such
         interest is sold and thereafter the Landlord shall be discharged from

5.2      SUBJECT TO SCHEDULE "E", if the Landlord is unable to deliver vacant
         possession of the Leased Premises on the Commencement Date by reason of
         the Landlord's failure to complete construction or to make available
         the services which the Landlord is hereby obligated to furnish or by
         reason of any previous tenant or occupant overholding or for any other
         reason whatsoever, then, until such time as the Landlord is able to
         deliver vacant possession of the Leased Premises WITH THE TURNKEY WORK
         COMPLETED, Rent and such other amounts for which the Landlord may be
         entitled to demand payment from the Tenant under the provisions of this
         Lease, shall abate in that proportion which the area of the Leased
         Premises which TENANT IS WILLING TO COMMENCE OPERATING ITS BUSINESS
         FROM bears to the Net Leasable Area of the Leased Premises.
         PROVIDED LANDLORD IS USING ALL COMMERCIALLY REASONABLE STEPS TO
         DELIVER VACANT POSSESSION OF THE PREMISES WITH THE TURNKEY WORK
         COMPLETED, Tenant hereby agrees to accept such abatement of Rent and
         Additional Rent in full settlement of and any and all claims which the
         Tenant may otherwise have against the Landlord by reason of the Leased
         Premises not being ready for occupancy on the Commencement Date.

         all or any installations or other work required to be completed by the
         Tenant in accordance with the provisions of this LEASE. The Tenant
         shall not be entitled to any abatement of Rent or Additional Rent where
         the Landlord's failure to obtain completion of the Leased Premises or
         to deliver vacant possession of the Leased Premises on the Commencement
         Date is due to any act or omission on the part of the Tenant. The
         decision of the Landlord's Architect shall be final and binding upon
         the parties hereto as to whether or not the Leased Premises are ready
         for occupancy by the Tenant, as to the proportion of the Leased
         Premises that is available for occupancy and as to the extent to which
         any delay in completion of the Leased Premises or in the delivery of
         vacant possession is due to any act or omission of the Tenant or its
         agents, servants or contractors. The Tenant shall, promptly upon the
         request by the Landlord, execute an acknowledgement of the date upon
         which complete and vacant possession of the Leased Premises is
         delivered to the Tenant. Notwithstanding the Landlord's failure to
         obtain completion of the Leased Premises or to deliver vacant
         possession of the Leased Premises on the Commencement Date, this Lease
         shall continue in full force and effect subject only to the abatement
         of Rent and Additional Rent as aforesaid and this Lease shall expire on
         the date specified in Paragraph 3.1 hereof notwithstanding such delay,

         part of this Lease or sublet or part with the possession of or in any
         way encumber all or part of the Leased Premises (each of the foregoing
         being a "TRANSFER") without the prior written consent of the Landlord,
         which consent shall not be unreasonably withheld OR DELAYED; provided
         however, such consent to any Transfer shall not relieve the Tenant from
         its obligations for the payment of Rent, Additional Rent and for the
         full and faithful observance and performance of the covenants, terms
         and conditions herein contained and any default by any recipient of the

         contained herein, the Landlord may, in its sole discretion, elect to
         cancel this Lease in preference to giving its consent. If the request
         for consent relates to only a part of the Leased Premises, the
         Landlord's rights to cancel this Lease will relate only to such part
         and in this event the Tenant will, at its expense, arrange for the
         partitioning of the Leased Premises so as to separate the part being
         Transferred from the remainder of the Leased Premises. If the Landlord
         elects to cancel all or part of this Lease, the Tenant will notify the
         Landlord in writing within ten (10) days thereafter of the Tenant's
         intention to refrain from such Transfer. If the Tenant fails to deliver
         notice within the ten (10) day period, the Tenant will be deemed to
         accept the foregoing and this Lease will be terminated or amended to
         reflect the surrender of the Transferred portion of the Leased Premises
         upon the expiration of the ten (10) day period and the Tenant shall, in
         either case, execute and deliver to the Landlord the Landlord's form of
         acknowledgement to this effect and vacate the Leased Premises (or
         relevant portion thereof) in the manner required in Section 33 herein.
         If the Tenant advises the Landlord that the Tenant has cancelled such
         Transfer in the manner set out above, each of the proposed Transfer,
         the Landlord's election to cancel this Lease or reduce the Leased
         Premises will become null and void in such instance but the Tenant
         shall remain liable for the Landlord's REASONABLE costs and expenses in
         connection therewith. If the Landlord shall have declined to elect to
         terminate this Lease, pursuant to the foregoing, the Tenant may
         Transfer such space to the Transferee in accordance with the terms and
         conditions of the Transfer previously presented to the Landlord subject
         to Paragraph 13.1 and the provisions of this Section 13 (including the
         requirement for obtaining the Landlord's prior written consent) shall
         continue to apply to such Transfer.

13.2.2   In all cases: (a) the Tenant shall not be released from any obligations
         under this Lease, as amended, supplemented, assigned, renewed and/or
         extended from time to time; (b) each of the Tenant and the Transferee
         shall execute and deliver to the Landlord, the Landlord's FORM OF
         AGREement pursuant to which the Tenant confirms the foregoing and the
         Transferee shall assume the Tenant's obligation for the payment of rent
         and for the full and faithful observance and performance of the
         covenants, terms and conditions herein contained; and (c) the Tenant
         shall pay all of the Landlord's costs and expenses in connection
         therewith.


                                     - 13 -




13.2.3   No Transfer shall be valid unless, prior to the execution thereof, the
         Tenant shall deliver to the Landlord duplicate originals of such
         agreement duly executed by the Tenant and Transferee along with the
         Landlord's form of agreement wherein such Transferee shall assume the
         Tenant's obligation for the payment of rent and for the full and
         faithful observance and performance of the covenants, terms and
         conditions herein contained as if it was the original tenant hereunder
         including those items referred to in Paragraph 13.2.2 above, PROVIDED
         THAT IN THE CASE OF A SUBLEASE SUCH OBLIGATIONS SHALL BE LIMITED TO THE
         SUBPREMISES FOR SUBTERM.

13.2.4   The Landlord's consent to any Transfer shall be further subject to the
         condition that all REASONABLE legal fees and expenses incurred by the
         Landlord in connection with the review by the Landlord and/or its
         solicitors of the Tenant's request to Transfer together with any legal
         fees and disbursements incurred in the preparation and review of any
         documentation therewith shall be the responsibility of the Tenant and
         shall be paid forthwith on demand. Failure to pay such fees and
         expenses shall be treated by the Landlord in the same manner as rent in
         arrears.

13.2.5   In the event that the rent or any other payment or consideration in
         connection with any Transfer by the Tenant is greater on a per square
         foot basis than that payable under this Lease, the excess shall be paid
         by the Tenant to the Landlord as Additional Rent.


13.3     NOTWITHSTANDING ANYTHING TO THE CONTRARY, TENANT SHALL NOT REQUIRE
         LANDLORD'S CONSENT (AND LANDLORD SHALL HAVE NO CANCELLATION RIGHT), but
         the Tenant shall provide prior notice to the Landlord, of an assignment
         or sublease to an affiliate (AS SUCH TERM IS DEFINED IN THE ONTARIO
         BUSINESS CORPORATIONS ACT), to the acquirer of the Tenant's business
         operations, or as a result of a merger or amalgamation.

13.4     The Landlord shall be liable for the performance of its covenants and
         obligations pursuant to this Lease so long as it owns or is in
         possession and control of the Development. In the event of any sale or
         other transfer of the Development, the Landlord shall UPON THE
         ASSUMPTION OF SUCH COVENANTS AND OBLIGATIONS BY THE PURCHASER OF THE
         BUILDING and without further agreement be relieved and released of all
         liability with respect to such covenants and obligations.

14.      RULES AND REGULATIONS

14.1     The Tenant and the Tenant's employees and all persons visiting and
         doing business with it on the Leased Premises shall be bound by and
         shall observe the Rules and Regulations attached to this Lease as
         Schedule "C" and such further and other reasonable rules and
         regulations made hereafter by the Landlord (provided same do not
         conflict with the terms of this Lease) relating to the Lands and the
         Building, the Leased Premises or the Common Areas of which prior notice
         in writing shall be given to the Tenant and all such rules and
         regulations shall be deemed to be incorporated into and form part of
         this Lease.

15.      USE OF PREMISES


15.1     The Leased Premises shall be used solely for the purpose of general
         business office use and for no other purpose; provided that such
         purposes, as aforesaid, shall comply with the terms of this Lease and
         all applicable laws, by-laws, regulations or other governmental
         ordinances from time to time in existence and the Tenant shall not
         carry on or permit to be carried on therein any other trade or business
         and the Tenant shall not do or omit or permit to be done or omitted
         upon the Leased Premises anything which shall cause the rate of
         insurance upon the Building to be increased and if the rate of
         insurance on the Building shall be increased by reason of the use made
         of the Leased Premises or by reason of anything done or omitted or
         permitted to be done or omitted by the Tenant or anyone permitted by
         the Tenant to be upon the Leased Premises, the Tenant shall on demand
         pay to the Landlord the amount of such increase. The Landlord


                                     - 14 -


         confirms that the use of the Leased Premises for general office
         purposes is not prohibited by the applicable municipal by-law at this
         time.

15.2     Without diminishing the restrictions in Paragraph 15.1 above, the
         Leased Premises shall not be used for the carrying on of any barter,
         trade or exchange of goods, or sale through promotional give-away
         gimmicks or any business involving the sale of second-hand goods,
         insurance salvage stock or fire sale stock, and shall not be used for
         any auction or pawnshop business, any fire sale, liquidation sale,
         bankruptcy sale, going-out-of-business sale, moving sale, bulk sale or
         any other business which, because of merchandising methods or
         otherwise, would tend to lower the first-class character of the
         Building.

15.3     Any use of the Leased Premises not in accordance with the design
         standards of the Building or any arrangement of partitions which
         interferes with the normal operation of the climate control system for
         the Building may require changes or alterations in the system or the
         ducts. Any changes or alterations so required after the Commencement
         Date, if such changes can be accommodated by the Landlord's equipment,
         shall be made by the Landlord, at the Tenant's expense, and only after
         such changes or alterations have received the Landlord's prior written
         consent. If installation of partitions, equipment or fixtures by or on
         behalf of the Tenant after the Commencement Date necessitates the
         rebalancing of any climate control equipment serving the Leased
         Premises, such work will be performed by the Landlord at the Tenant's
         expense. To the cost of any work performed by the Landlord on the
         Tenant's behalf shall be added an amount equal to fifteen percent (15%)
         of the total expense thereof, representing the Landlord's overhead and
         administrative costs, and all amounts owing shall be payable by the
         Tenant upon demand.

16.      TENANT'S INSURANCE

16.1     The Tenant shall provide at its own expense and keep in force, during
         any rent-free period and continuously throughout the Term of this
         Lease and any renewal thereof, in the name of the Tenant, the Landlord
         and the Landlord's mortgagee, the following:

16.1.1   Comprehensive general public liability insurance on an occurrence basis
         with respect to the business carried on, in or from the Leased Premises
         and the Tenant's use and occupancy of the Leased Premises and of any
         other part of the Building or Lands with coverage for any one
         occurrence or claim of not less than TWO MILLION DOLLARS
         ($2,000,000.00), which insurance shall include the Landlord as an
         additional insured, and shall contain cross liability and severability
         of interest clauses and shall protect the Landlord in respect of claims
         by the Tenant as if the Landlord were separately insured;

16.1.2   Insurance with respect to fire and such other perils as are from time
         to time included in the usual extended coverage endorsement covering
         the leasehold improvements, trade fixtures and the furniture and the
         equipment in the Leased Premises for not less than the full replacement
         cost thereof, which insurance shall include the Landlord and any
         mortgagee of the Building as ADDITIONAL insureds as their respective
         interests may appear;

16.1.3   Business interruption insurance in such amount as will reimburse the
         Tenant for direct or indirect loss of earnings attributable to any
         peril commonly insured against by prudent tenants or attributable to
         the prevention of access to the Leased Premises as a result of any such
         peril; and

16.1.4   Insurance against any such other peril and in such reasonable amounts
         as the Landlord, acting reasonably, may from time to time reasonably
         require upon not less than thirty (30) days notice, such requirement to
         be made on the basis that the required insurance is customary at the
         time for reasonably prudent tenants occupying premises similar to the
         Leased Premises.


                                     - 15 -



16.2     Where the Tenant may desire to receive indemnity by way of insurance
         for any property, work or thing whatever, the Tenant shall insure same
         for its own account and shall not look to the Landlord for
         reimbursement or recovery in the event of loss or damage from any
         cause, whether or not the Landlord has insured same and recovered
         therefor.

16.3     To the extent only of insurance proceeds actually received by the
         Landlord under the policy or policies of insurance maintained OR
         REQUIRED HEREUNDER TO BE MAINTAINED BY LANDLORD, THE LANDLORD AGREES TO
         RELEASE THE TENANT FOR ANY LOSS SUSTAINED.

16.4     The Tenant agrees to release and hold harmless the Landlord for loss or
         damage to the property of the Tenant and in addition all policies of
         insurance required to be written on behalf of the Tenant pursuant to
         Paragraph 16.1.2 shall contain a waiver of any subrogation rights which
         the Tenant's insurers may have against the Landlord and against those
         for whom the Landlord is in law responsible.

16.5     Each policy of insurance referred to in Paragraph 16.1 hereof shall be
         taken out with insurers qualified to carry on business in the Province
         of Ontario, who are reasonably acceptable to the Landlord and shall be
         in a form satisfactory, from time to time, to the Landlord and shall
         further be non-contributing with, and shall apply only as primary and
         not excess to, any other insurance available to the Landlord or to the
         Landlord's mortgagee and shall not be invalidated as respects the
         interest of the Landlord and the mortgagee by reason of any breach or
         violation of any warranties, representations, declarations or
         conditions contained in the policy, and finally, shall contain an
         undertaking by the insurers to notify the Landlord in writing by
         registered mail, not less than thirty (30) days prior to any material
         change, cancellation or termination thereof. The Tenant shall furnish
         to the Landlord certificates (in form satisfactory to the Landlord) of
         the insurance companies evidencing the maintenance of all insurance
         policies required to be maintained by the Tenant pursuant to Paragraph
         16.1 provided, however, that the Tenant shall provide photocopies of
         such insurance policies if requested, in writing, by the Landlord or
         the Landlord's mortgagee.

17.      CANCELLATION OF INSURANCE

17.1     If any policy of fire and extended coverage insurance upon the Building
         shall be cancelled by the insurer by reason of the use or occupation of
         the Leased Premises or any part thereof by the Tenant or by any
         assignee or subtenant of the Tenant or by anyone permitted by the
         Tenant to be upon the Leased Premises, and if such policy coverage is
         not replaced by the Tenant, the Landlord may at its option terminate
         this Lease forthwith by leaving upon the Leased Premises notice in
         writing of its intention so to do and thereupon Rent, Additional Rent
         and any other payment for which the Tenant is liable under this Lease
         shall be apportioned and paid in full to the date of such termination
         and the Tenant shall immediately deliver up possession of the Leased
         Premises to the Landlord and the Landlord may re-enter and take
         possession of the same.

18.      OBSERVANCE OF LAW

18.1     The Tenant covenants with the Landlord to comply with all provisions of
         law including without limitation, all federal and provincial
         legislative enactments, building health and fire by-laws, and any
         other governmental or municipal regulations which relate to the
         Tenant's equipment, operation and use of the Leased Premises, and to
         the making of any repairs, replacements, alterations, additions,
         changes, substitutions or improvements of or to the Leased Premises.
         The Tenant covenants to comply with all police, fire and sanitary
         regulations imposed by any federal, provincial or municipal authority,
         and with their regulations and other requirements governing the conduct
         of any business conducted in the Leased Premises. The Tenant shall not
         be and the Landlord shall be responsible for any non-compliance of the
         LEASED Premises with any applicable laws, by-laws, orders and
         directives, including without limitation with


                                     - 16 -



         respect to environmental and hazardous waste, existing prior to the
         Tenant taking occupancy of the LEASED Premises.

19.      WASTE AND NUISANCE

19.1     The Tenant shall not do or suffer any waste or damage or disfiguration
         or injury to the Leased Premises or the fixtures and equipment thereof
         or permit or suffer any overloading of the floors thereof and shall not
         place therein any excessively heavy safe, heavy business machinery,
         heavy computers, data processing machines, or other heavy things
         without first obtaining the consent in writing of the Landlord and, if
         requested, by its superintending Architect, and shall not use or permit
         to be used any part of the Leased Premises for any dangerous, noxious
         or offensive trade or business, and shall not cause or permit any
         nuisance in, at or on the Leased Premises.

20.      ENTRY BY LANDLORD

20.1     The Tenant agrees that it will permit the Landlord, its servants or
         agents to enter upon the Leased Premises at any time and from time to
         time on reasonable WRITTEN NOTICE to Tenant (except in the case of an
         actual or apprehended emergency when no such notice shall be required)
         for the purpose of inspecting and of making repairs, alterations or
         improvements to the Leased Premises or to the Building, and the Tenant
         shall not be entitled to compensation for any inconvenience, nuisance
         or discomfort occasioned thereby it being understood and agreed that
         the Landlord, its servants, agents or employees, shall make such entry
         after business hours whenever possible and at all times so as not to
         unduly interfere with the business being carried on by the Tenant. The
         Landlord, its servants or agents may at any time and from time to time
         UPON REASONABLE PRIOR NOTICE enter upon the Leased Premises to remove
         any article or remedy any condition which in the opinion of the
         Landlord, reasonably arrived at, would be likely to lead to
         cancellation of any policy of insurance as referred to in Paragraph
         17.1 hereof, and such entry by the Landlord shall not be deemed to be a
         re-entry.

21.      INDEMNITY

21.1     TO THE EXTENT NOT COVERED BY INSURANCE MAINTAINED OR REQUIRED TO BE
         MAINTAINED BY LANDLORD, the Tenant covenants and agrees to reimburse,
         indemnify and save harmless the Landlord against and from any and all
         claims by the Landlord and by other parties, including without
         limiting the generality of the foregoing, from any breaches of this
         Lease and all claims for personal injury or property damage or damage
         to the Development arising from the conduct of any work or by or
         through any act or omission of the Tenant; or any assignee, subtenant,
         agent, contractor, servant, employee, invitee or licensee of the
         Tenant, or any person whose presence in or about the Development arises
         because of the Tenant's occupation of the Leased Premises, and from all
         costs, counsel fees, expenses and liabilities incurred in or about any
         such claim or any action or proceeding brought thereon. This indemnity
         shall survive the expiry or sooner determination of this Lease.

22.      EXHIBITING PREMISES

22.1     The Tenant shall, upon prior notice from the Landlord and provided the
         Landlord does not unduly interfere with the Tenant's business, permit
         the Landlord or its agents to exhibit the Leased Premises to
         prospective tenants during normal business hours during the last six
         (6) months of the Term and to prospective or actual investors, lenders
         or purchasers throughout the Term.

23.      ALTERATIONS

23.1     The Tenant covenants that it will not make, install or erect in or to
         the Leased Premises any installations, alterations, additions or
         partitions without first submitting the drawings and specifications to
         the Landlord and obtaining the Landlord's prior written consent in each
         instance, which consent shall not be



                                     - 17 -



         unreasonably withheld. Furthermore, the Tenant must obtain the
         Landlord's prior written consent to any change or changes, in such
         drawings or specifications submitted as aforesaid, subject to the
         payment of the cost to the Landlord of having its architects approve of
         such changes, prior to proceeding with any work based on such drawings
         or specifications. Such work may be performed by contractors engaged by
         the Tenant for the initial installation of leasehold improvements only
         but, in each case, under written contract, approved in writing by the
         Landlord and subject to all reasonable conditions which the Landlord
         may impose. The Landlord may nevertheless, at its option, thereafter
         require that the Landlord's contractors be engaged for any mechanical,
         electrical work or other leasehold improvement at the Tenant's sole
         cost, together with a sum equal to fifteen percent (15%) of such costs
         representing the Landlord's overhead and administrative costs. Without
         limiting the generality of the foregoing, any work performed by or for
         the Tenant shall be performed by competent workmen whose labour union
         affiliations are not incompatible with those of any workmen who may be
         employed in the Building by the Landlord, its contractors or
         sub-contractors. All such installations, alterations, additions,
         changes and work performed by or for the Tenant shall conform to all
         building by-laws and shall conform to all federal, provincial and
         municipal rules and regulations, if any, then in force affecting the
         Leased Premises, the Building and the Lands and such installations,
         alterations, additions, changes and work performed by or for the Tenant
         shall be completed in a good and workmanlike manner. The Tenant
         covenants that the Tenant will not suffer or permit during the term
         hereof any construction or other liens for work, labour services or
         materials ordered for or by the Tenant or for the cost of which the
         Tenant may be in any way obligated to attach to the Leased Premises or
         to the Building and that whenever and so often as any such liens shall
         attach or claims therefor shall be filed, the Tenant shall forthwith
         procure the discharge thereof by payment or by giving security or in
         such other manner as is or may be required or permitted by law, failing
         which the Landlord may do so (BY PAYING INTO COURT ONLY) at the
         Tenant's sole risk and expense and the Tenant shall forthwith pay all
         of the Landlord's costs and expenses in connection therewith along with
         an administration fee equal to fifteen percent (15%) of the Landlord's
         costs and expenses in connection therewith.

23.2     The Landlord hereby reserves the right at any time and from time to
         time to make changes in, additions to, subtractions from or
         rearrangements of the Building (EXCLUDING THE LEASED PREMISES)
         including, without limitation, all improvements at any time thereon to
         the Common Areas and all entrances and exits thereto; to grant, modify
         and terminate easements or other agreements pertaining to the use and
         maintenance of all or parts of the Common Areas; to close all or any
         portion of the Common Areas to such extent as may in the opinion of the
         Landlord be necessary to prevent accrual of any rights to any persons
         therein and/or to make changes or additions to the pipes, conduits,
         utilities and other necessary building services in the Leased Premises
         which serve other premises and/or the Building. In addition to its
         other rights to relocate herein at any time or times, the Landlord
         shall have the right to make any changes in, additions to, deletions
         from or relocations of any part of the Development (EXCLUDING THE
         LEASED PREMISES) including prior to the commencement of the Term, the
         Landlord may alter or relocate any part or parts of the Common Areas.
         NOTWITHSTANDING ANYTHING TO THE CONTRARY, THE LANDLORD SHALL NOT
         PREVENT ACCESS TO OR THE USE OF THE LEASED PREMISES BY TENANT AND
         TENANT'S EMPLOYEES AND INVITEES.

23.3     The Tenant acknowledges that portions of the Building, the Common Areas
         and/or the Development may be under construction during the Term, and
         that after the Commencement Date, the Landlord will minimize
         interference with the Tenant's use of AND ACCESS TO the Leased
         Premises. PROVIDED LANDLORD MINIMIZES INTERFERENCE WITH THE TENANT'S
         USE OF AND ACCESS TO THE LEASED PREMISES, the Tenant shall not have any
         right to object to or to make any claim on account of the exercise by
         the Landlord of any of its rights under this Section 23,
         notwithstanding any change in the size of the Common Areas, the
         Building and/or the Development any nuisance, inconvenience or loss to,
         interference with or


                                     - 18 -



         obstructions, interruption, dislocation or suspension of any utilities
         or the use of the Common Areas, the Building and/or the Development.

23.4     RENT AND ADDITIONAL RENT SHALL ABATE FOR THE PERIOD DURING WHICH
         TENANT, ACTING REASONABLY, IS UNABLE TO CARRY ON BUSINESS IN ALL OR
         PART (IN WHICH CASE THE ABATEMENT WILL HE ON A PRORATA BASIS) OF THE
         LEASED PREMISES AS A RESULT OF LANDLORD'S ALTERATIONS OR CONSTRUCTION

24.      GLASS AND OVERLOADING

24.1     GLASS.

         Any glass and trimmings in, upon or about the doors and windows of the

         such destruction or damage.

36.1.2   If the damage or destruction is such that the Leased Premises is
         rendered wholly unfit for occupancy or it is impossible or unsafe to
         use and occupy it OR ACCESS IT, and if in either event, the damage, in
         the opinion of the Landlord's Architect, to be given to the Tenant
         within ten (10) days of the happening of such damage or destruction,
         cannot be repaired with reasonable diligence within one hundred and
         eighty (180) days from the happening of such damage or destruction,
         then the Landlord OR TENANT may within five (5) days next succeeding
         the giving of the Landlord's Architect's opinion as aforesaid,
         terminate this Lease by giving to the OTHER notice in writing of such
         termination, in which event this Lease and the Term hereby demised
         shall cease and be at an end as at the date of such destruction or
         damage and the Rent and Additional Rent payable pursuant hereto shall
         be apportioned and paid in full to the date of such destruction or
         damage. If the Landlord OR TENANT does not terminate this Lease, then
         to the extent the Landlord receives insurance proceeds from the
         Landlord's insurance pursuant to Paragraph 35.1.1 (less the Landlord's
         costs and expenses in connection therewith), the Landlord shall repair
         the Building with all reasonable speed and the Rent and Additional Rent
         payable pursuant hereto shall abate.

36.1.3   If the damage be such that the Leased Premises is wholly unfit for
         occupancy or if it is impossible or unsafe to use or occupy it, but if
         in either event the damage, in the opinion of the Landlord's Architect,
         to be given to the Tenant within ten (10) days from the happening of
         such damage, can be repaired with reasonable diligence within one
         hundred and eighty (180) days from the happening of such damage, then
         the Rent payable pursuant to Paragraph 4.1 hereof shall abate and the
         Landlord shall repair the damage with all reasonable speed.

36.1.4   If, in the opinion of the Landlord's Architect, the damage to the
         Leased Premises can be made good, as aforesaid, within one hundred and
         eighty (180) days of the happening of such destruction or damage and
         the damage is such that the Leased Premises is capable of being
         partially used for the purposes for which it is hereby demised, then
         until such damage has been repaired, the Rent payable pursuant to
         Paragraph 4.1 hereof shall abate in the proportion that the part of the
         Leased Premises rendered unfit for occupancy bears to the whole of the
         Leased Premises, and the Landlord to the extent the Landlord receives
         insurance proceeds from the Landlord's insurance (less its costs and
         expenses) pursuant to Paragraph 35.1.1, shall repair the damage with
         all reasonable speed.

36.1.5   In the event the Landlord shall elect to repair, reconstruct or rebuild
         the Building of which the Leased Premises forms a part in accordance
         with the provisions of this Paragraph 36.1, it is acknowledged and
         agreed by the Tenant that the Landlord shall be entitled to use plans
         and specifications and working drawings in connection therewith other
         than those used in the original construction of the Building.

36.1.6   The decision of the Landlord's Architect as to the time within which
         the Building and/or the Leased Premises can or cannot be repaired, the
         state of tenantability of the Leased Premises and/or the Building and
         as to the date on which the Landlord's work of repair is completed,
         shall be final and binding on the parties hereto.

         of or damage or injury to any property belonging to the Tenant or to

         only to the extent of insurance proceeds actually received by the
         Landlord. Notwithstanding the foregoing or anything else contained
         herein, the Landlord shall not be liable, TO THE EXTENT OF INSURANCE

         drainage pipes or plumbing works of the Building, or from any other
         place or quarter or for any damage caused by or attributable to the
         condition or arrangement of any electric or other wiring or for any

         performing alterations to or re-letting of the Leased Premises by the

         Premises or any part thereof as the Landlord may reasonably consider
         requisite or necessary, without any liability to the Tenant therefor,
         or for any damage resulting thereby, and without constituting a
         re-entry of the Leased Premises or termination of this Lease and
         without being in breach of the Landlord's covenants hereunder and
         without thereby being deemed to infringe upon any of the Tenant's
         rights pursuant hereto and, in such case, the Tenant shall pay to the
         Landlord forth-with upon demand all amounts paid by the Landlord to
         third parties in respect of such default and all reasonable costs of
         the Landlord in remedying or attempting to remedy any such default plus
         an additional fifteen percent (15%) of the amount of such cost for the
         Landlord's inspection, Supervision, overhead and profit. The Landlord
         shall have no liability to the Tenant for any loss or damage resulting
         from any such action by the Landlord, and entry by the Landlord under
         the provisions of this Paragraph 39.2.3 shall not constitute a breach
         of the covenant for quiet enjoyment or an eviction; and/or

39.2.4   obtain damages from the Tenant, including, without limitation, if this
         Lease is terminated by the Landlord, all deficiencies between all
         amounts which would have been payable by the Tenant for what would have
         been the balance of the Term for such termination, and all amounts
         actually received by the Landlord for such period of time.

39.3     In case suit shall be brought for recovery of possession of the Leased
         Premises, or for the recovery of Rent or Additional Rent, or because of
         the breach of any other covenants herein contained on the part of the
         Tenant to be kept or performed, the Tenant shall pay to the Landlord
         all expenses incurred therefor (including all solicitors' fees).

39.4     In case of removal by the Tenant of the goods and chattels of the
         Tenant from the Leased Premises, the Landlord may follow same for
         thirty (30) days in the same manner as is provided for in the
         Commercial Tenancies Act R.S.O. 1990 as amended, renamed and/or
         repromulgated from time to time.

         Landlord against any amounts due and payable hereunder in such manner
         as the Landlord in its sole discretion sees fit.

39.6     It shall not be unreasonable for the Landlord to withhold its consent
         at any time when the Tenant is in default hereunder or has been in
         default hereunder on a consistent basis FOR WHICH TENANT HAS RECEIVED
         WRITTEN NOTICE OF DEFAULT.

         the Tenant of any term, covenant or condition of this Lease, regardless
         of the Landlord's knowledge of such preceding breach at the time of
         payment or acceptance of Rent or Additional Rent. No covenant, term or
         condition of this Lease shall be deemed to have been waived by either
         party unless such waiver is in writing and signed by the party.

41.      DISTRESS

41.1     The Tenant waives and renounces the benefit of any present or future
         statute taking away or limiting the Landlord's right of distress, and
         covenants and agrees that notwithstanding any such statute none of the
         goods, chattels and/or trade fixtures of the Tenant on the Leased
         Premises at any time during the Term shall be exempt from levy distress
         for rent in arrears.

         Lease, the Landlord, in addition to all other rights, shall have the
         right to enter the Leased Premises as the agent of the Tenant either by

         re-letting the Leased Premises on account of the Rent and Additional
         Rent under this Lease, and the Tenant shall be liable to the Landlord
         for the deficiency, if any.

43.      RIGHT OF TERMINATION

43.1     The Tenant Anther covenants and agrees that if the Landlord becomes
         entitled to re-enter upon the Leased Premises under any of the default
         provisions of this Lease, the Landlord in addition to all other rights,
         shall have the right to terminate this Lease and the Term forthwith by
         giving notice in writing addressed to the Tenant of its intention so to
         do, and thereupon Rent and Additional Rent shall be computed,
         apportioned and paid in full to the date of such determination of this

         possession of the Leased Premises to the Landlord and the Landlord may
         re-enter and take possession of the same.

44.      TENANT TO PAY RENT AND PERFORM COVENANTS

         prime commercial borrowers from time to time (the "DEFAULT RATE") from
         the date upon which same was due until actual payment thereof. The
         Tenant covenants to observe and perform all the terms and provisions of

46.      OVERHOLDING

46.1     If the Tenant remains in possession of the Leased Premises after the
         Term with the prior written consent of the Landlord but without
         executing a new lease, there is no tacit renewal or extension of this
         Lease despite any statutory provision or legal presumption to the
         contrary and the Tenant will occupy the Leased Premises as a Tenant
         from month to month at a monthly Rent payable in advance on the first
         day of each month equal to the total of: (a) 150% of the monthly amount
         of Rent for the last month of the Term; and (b) the amount of
         Additional Rent payable by the Tenant in the last full month prior to
         the expiration of the Term, and the Tenant will comply with the same
         terms, covenants and conditions as are in this Lease as far as they
         apply to a monthly tenancy including the payment of Rent and Additional
         Rent unless the Landlord has previously advised the Tenant to vacate
         the Leased Premises in which case no notice will be required. Provided
         further that the Landlord may at any time and in its sole discretion
         terminate said overholding on five (5) days prior notice to the Tenant.
         Notwithstanding the foregoing, nothing contained herein shall be
         construed to give Tenant the right to hold over at any time, and
         Landlord may exercise any and all remedies at law or in equity to
         recover possession of the Leased Premises, as well as any damages
         incurred by Landlord due to Tenant's failure to vacate the Leased
         Premises and deliver possession to Landlord as provided herein. Nothing
         herein shall limit the liability of Tenant in damages or otherwise. In
         that regard, the Tenant acknowledges and agrees that the Landlord will
         incur substantial damages in the event that it is unable to provide
         vacant possession of all or part of the Leased Premises to future
         tenants in a timely manner.

47.      TENANT PARTNERSHIP OR GROUP

47.1     If the Tenant is a partnership, other than a limited partnership, each
         entity who is or subsequently becomes a member of the partnership or
         any successor thereof will be and shall continue to be subject to and
         jointly and severally liable for the performance and observance of the
         terms, covenants and conditions of this Lease by the Tenant, even if
         said entity ceases to be a member of such partnership or successor
         thereof.

48.      DEMOLITION

48.1     INTENTIONALLY DELETED.

49.      ACCRUAL OF RENT

49.1     Rent and Additional Rent shall be considered as accruing from day to
         day, and where it becomes necessary for any reason to calculate such
         Rent or Additional Rent for an irregular period of less than one year
         an appropriate apportionment and adjustment shall be made. Where the
         calculation of any Additional Rent is not made until after the
         termination of this Lease, the obligation of the Tenant to pay such
         Additional Rent shall survive the termination of this Lease and such

                          METHOD OF FLOOR MEASUREMENT



         The following sets out the methods of measuring areas in the Complex:

1.1      Total Leaseable Area of the Building

The calculation of the Total Leaseable Area of the Building whether rented or
not shall be determined by the Landlord's Architect upon Landlord's request. The
total Leaseable Area of the Building shall consist of the aggregate of all of
the gross leaseable areas in the Building which are leased or which are capable
of being leased and which are designed to be leased. The Total Leaseable Area of
the Building shall be adjusted from time to time to give effect to any
structural, functional or other change affecting the same.

2.1      Net Leaseable Area of the Leased Premises

The Net Leaseable Area of the Leased Premises shall be computed by measuring
from the top surface of the subfloor to the bottom surface of the structural
ceiling and from the inside of the exterior glass finish to the outside office
side of the corridor or other permanent partitions and to the centre of
partitions that separate the Leased Premises from adjoining rental area (if any)
without deductions for columns or projections necessary to the Building of which
the Leased Premises forms a part and shall exclude Building Service Areas and
shall exclude the Accessory Areas or Tenant's Proportionate Share of such
Accessory Areas, except that in the event of a tenant leasing an entire floor,
the Net Leaseable Area of the Leased Premises shall be equal to the Gross
Leaseable Area of the Leased Premises.

3.1      Total Leaseable Area of the Development

The calculation of the Total Leaseable Area of the Development whether rented or
not shall be determined by Landlord's Architect upon Landlord's request. The
total Leaseable Area of the Development shall consist of the aggregate of all of
the gross leaseable areas in the Development which arc leased or which are
capable of being leased and which are designed to be leased. The Total Leaseable
Area of the Development shall be adjusted from time to time to give effect to
any structural, functional or other change affecting the same.
