      A. Sublandlord is the tenant under an Office Lease (the "Master Lease")
with 391102 B.C. Ltd. (the "Master Landlord"), which was originally, executed on

of office space (the "Premises") located in Suites 300 and 400 of the building
(the "Building") located at 4621 Canada Way, Burnaby, BC.

      B. Subtenant desires to sublease from Sublandlord a portion of the
Premises (the "Subleased Premises"), which Subleased Premises are defined as

Subleased Premises to Subtenant on the terms, covenants and conditions stated in
this Sublease, which includes any terms, covenants and conditions in the
exhibits attached hereto.

      NOW, THEREFORE, in consideration of the mutual covenants contained in this
Sublease, and for valuable consideration, the receipt and sufficiency of which
are hereby acknowledged by the parties, the parties agree as follows:

      1. SUBLEASE. Sublandlord hereby subleases to Subtenant and Subtenant
subleases from Sublandlord the Subleased Premises, subject to the terms,
covenants, and conditions contained in this Sublease. Sublandlord and Subtenant
agree that the Subleased Premises contain the rentable area as specified in the
Sublease Summary.

      2. TERM. The term of this Sublease shall commence on the "Commencement
Date" set forth in the Sublease Summary and, unless sooner terminated as
provided in the Master Lease, will expire on the "Expiration Date" set forth in
the Sublease Summary.

      3. BASIC RENT. Subtenant shall pay to Sublandlord as basic monthly rental
for the Premises the amount set forth in Clause 6 of the Sublease Summary hereto
(the "Basic Rent") in advance of the first day of each month. Basic Rent and

<PAGE>

      6. MASTER LEASE. As applied to this Sublease, the words "Landlord" and
"Tenant" in the Master Lease will be deemed to refer to Sublandlord and
Subtenant, respectively, under this Sublease. The covenants, agreements,
provisions, and conditions of the Master Lease -- to the extent that they relate
to the Subleased Premises and to the extent that they are not inconsistent with
the terms of this Sublease -- are made a part of and incorporated into this
Sublease as if recited in full in this Sublease. As between the parties to this
Sublease only, in the event of a conflict between the terms of the Master Lease
and the terms of this Sublease, the terms of this Sublease will control.

            6.1. MASTER LANDLORD'S PERFORMANCE. Subtenant recognizes that
Sublandlord is not in a position to render any of the services or to perform any
of the obligations required of Master Landlord by the terms of the Master Lease.
Therefore, despite anything to the contrary in this Sublease, Subtenant agrees
that performance by Sublandlord of its obligations under this Sublease is
conditioned on performance by the Master Landlord of its corresponding
obligations under the Master Lease, and Sublandlord will not be liable to
Subtenant for any default of the Master Landlord under the Master Lease,
provided that the Master Landlord's failure to perform is not related to a
default by the Sublandlord under the Master Lease and further provided that the
Sublandlord is using all commercially reasonable efforts to cause the Master
Landlord to perform such obligations.

            6.2 MASTER LANDLORD'S CONSENT. Whenever the consent of the Master
Landlord is required by the Subtenant under the Master Lease, Sublandlord shall
use all commercially reasonably efforts to obtain, at Subtenant's sole cost and
expense, that consent on behalf of Subtenant.

            6.3 PRESERVATION OF MASTER LEASE. Sublandlord agrees to perform all
of its obligations under the Master Lease and not to terminate or surrender the
Master Lease voluntarily, or modify the Master Lease in a manner that adversely
affects Subtenant's rights under this Sublease.

      7. VARIATIONS FROM MASTER LEASE. As between Sublandlord and Subtenant, the
terms and conditions of the Master Lease are modified as stated below in this
section 7:

            7.1 INSURANCE AND CONDEMNATION PROCEEDS. Despite anything contained
in the Master Lease to the contrary, as between Sublandlord and Subtenant only,
in the event of damage to or condemnation of the Subleased Premises, all
insurance proceeds or condemnation awards received by Sublandlord under the
Master Lease will be deemed to be the property of Sublandlord, and Sublandlord
will have no obligation to rebuild or restore the Subleased Premises.

            7.2 NOTICES. Any notice required or permitted to be given under this
Sublease shall be in writing and shall be by personal delivery or by mail.

prepaid, whichever first occurs. At the date of execution of this Lease, the
addresses of Sublandlord and Subtenant are as set forth above. After the

Lease that Subtenant is obligated to perform under the provisions of this
Sublease; or (b) any person as a result of Subtenant's use or occupancy of the

earlier termination of the Master Lease or this Sublease.

of Five (5) years (the "Term") commencing on January 1, 2002and expiring on
December 31, 2006, upon the terms and conditions contained in the Lease;

(B) Pursuant to a sublease made the 13th day of January, 2003 (the "Sublease")
the Sublandlord has agreed to sublease the Leased Premises to the Subtenant
effective the 1st day of May, 2003 on the terms and conditions contained in the

Sublandlord's obligations under the Lease on the terms and conditions contained
in the Indemnity Agreement;

(D) The Landlord has agreed to consent to the Sublease on the terms and
conditions contained herein.

NOW THEREFORE THIS AGREEMENT WITNESSES that in consideration of the Landlord's
consent herein contained and other good and valuable consideration, the parties
agree as follows:

1.    The Landlord hereby consents to the subletting of the Leased Premises by
      the Sublandlord to the Subtenant pursuant to the terms of the Sublease for
      a term commencing on the 1st day of May, 2003 and expiring on the 30th day
      of December, 2006 (the "Sublease Term"), subject to the performance and
      observance of the terms, covenants and conditions in the Lease (save only
      for payment of Minimum Rent reserved in the Lease) and subject to the
      Subtenant using the Leased Premises only for the purposes permitted by the
      Lease. This consent is given upon the basis that the Landlord does not
      acknowledge or approve of any of the terms of the Sublease between the
      Subtenant and the Sublandlord except for the said subletting itself.

2.    The Subtenant hereby confirms that it accepts the current state of repair
      of the Leased Premises and covenants and agrees with the Landlord to
      observe, comply with and perform all terms, covenants and conditions in
      the Lease insofar as they are applicable to the Leased Premises during all
      of the Sublease Term and any renewals or extensions thereof (save only for
      payment of the Minimum Rent reserved therein) as and when the same are to
      be performed by the tenant thereunder pursuant to the terms of the Lease,
      including without limitation, all of the repair and restoration
      obligations set forth in the Lease arising after the commencement of the
      Sublease Term. The Subtenant acknowledges that it has received and
      reviewed a copy of the Lease.

      "NOTWITHSTANDING THE ABOVE, THE SUBLANDLORD ACKNOWLEDGES THAT THE
      SUBTENANT SHALL HAVE NO OBLIGATION TO RESTORE THE SUBLEASED PREMISES TO
      SHELL CONDITION AT THE END OF

<PAGE>

                                       - 3 -

      THE SUBLEASE TERM AND WILL INDEMNIFY THE SUBTENANT OF THESE OBLIGATIONS
      ACCORDINGLY."

3.    This Agreement shall in no way affect or release the Sublandlord from its
      liabilities and responsibilities under the Lease, notwithstanding the
      Landlord's grant of consent to the Sublease, which is given without
      prejudice to the Landlord's rights under the Lease. The Sublandlord hereby
      acknowledges and agrees with the Landlord that it shall remain liable to
      the Landlord in respect of all the terms, covenants and conditions in the
      Lease on the part of the tenant to be observed and performed including,
      without limiting the generality of the foregoing, the payment of all Rent
      due to the Landlord under the Lease:

4.    This Agreement shall not be deemed to authorize any further assignments or
      subletting or parting with or sharing possession of the Leased Premises or
      any part thereof without the further consent of the Landlord as required
      under the Lease.

5.    The Subtenant hereby covenants and agrees with the Landlord not to assign
      this Agreement, or sublet or otherwise part with or share possession of
      the Leased Premises or any part thereof, without the prior written consent
      of the Landlord. In no event shall any such consent release (or be deemed
      to release) the Subtenant in any regard whatsoever from any of its
      obligations or liabilities under or pursuant to this Agreement, unless
      agreed otherwise in writing by the Landlord in such consent.

6.    The Subtenant hereby covenants and agrees with the Landlord that in no
      event shall the Landlord be:

      (a)   liable to the Subtenant for any act, omission or circumstances of
            the Sublandlord; or

      (b)   subject to any set-offs or defences that the Subtenant might have as
            against the Sublandlord.

7.    Notwithstanding the Landlord's grant of consent herein, the Sublease
      shall, at the option of the Landlord, terminate if the Lease shall
      terminate pursuant to the terms thereof or by operation of law or by
      re-entering and termination by the Landlord for breach of the Lease. In
      the event of such termination, the Subtenant shall deliver up the Leased
      Premises to the Landlord in compliance with all of the provisions of the
      Lease and in the condition required under the Lease.

8.    The Sublandlord and the Subtenant hereby covenant and agree with the
      Landlord that all monies owing by the Subtenant to the Sublandlord under
      the Sublease in respect of the Leased Premises shall, at the sole option
      of the Landlord, be paid directly by the Subtenant to the Landlord, if so
      directed by the Landlord in writing. All payments received by the Landlord
      pursuant to this Section shall be credited by the Landlord as against the
      amounts payable by the Sublandlord to the Landlord under the Lease.

9.    The Sublandlord covenants and agrees to pay to the Landlord any and all
      excess rent, monies or other consideration received from the Subtenant
      under the Sublease over and

<PAGE>

                                       - 4 -

      above the Rent payable by the Sublandlord to the Landlord under the Lease
      upon receipt thereof from the Subtenant.

10.   The Sublandlord and the Subtenant shall jointly and severally be liable
      for and shall indemnify the Landlord against all legal costs incurred by
      the Landlord with respect to the subletting referred to herein and the
      Landlord's consent with respect thereto.

11.   The Indemnifier covenants and agrees with the Landlord that its
      indemnification of the Sublandlord's obligations under the Indemnity
      Agreement shall continue in full force and effect notwithstanding the
      Landlord's grant of consent herein and the Indemnifier shall continue to
      be bound to the Landlord on the terms and as provided in the Indemnity
      Agreement.

12.   This Agreement shall be governed by and construed in accordance with the
      laws of the Province in which the Building is situated and the federal
      laws of Canada applicable therein.

13.   This Agreement shall enure to the benefit of and be binding upon the
      parties hereto and their respective heirs, administrators, personal
      representatives, successors and permitted assigns.

14.   Words and phrases used in this Agreement shall have the same meanings
      ascribed to them in the Lease unless otherwise specifically defined
      herein.

15.   This Agreement is not personally binding upon and that resort shall not be
      had to, nor shall recourse or satisfaction be sought from, the private
      property of the unitholders of Investors Real Property Fund (the "Fund"),
      trustees, directors, officers, employees or agents of the trustee or
      manager of the fund, it being intended and agreed that only the property

configurations of the Common Areas and Facilities and to make alterations or
additions to and build additional storeys on the Building. The Landlord also
reserves the right to construct other buildings or improvements on the Land from
time to time and to make alterations or additions thereto and to construct

7.3         PARKING.

            (a)   Subject to the by-laws, rules and regulations of the Landlord,
                  the Tenant and its employees, agents, customers and invitees
                  shall have the right, while at the Premises, in common with
                  all others from time to time entitled thereto, to park their
                  passenger motor vehicles for a reasonable period of time each
                  day upon that portion of the Land designated for vehicle
                  parking and not exclusively reserved for the use of other
                  Tenants of the Building. The Landlord may cause to be removed
                  at the cost of the Tenant, such vehicles as may be left on the
                  Land while apparently uninsured, unlicensed or abandoned. The
                  Landlord grants to the Tenant for the Term, for use by the
                  Tenant, the right and license to use that number of parking
                  spaces set out in article 1.1(l), and during the first year
                  of the Term the Tenant shall pay to the Landlord or its
                  parking lot operator the rental rates of $40.00 for each
                  surface parking space and $50.00 for each underground parking
                  space. After the first year of the Term, the Tenant shall pay
                  for parking the reasonable rental rates established by the
                  Landlord or its parking lot operator from time to time. It is
                  understood and agreed that in setting its parking rental rates
                  the Landlord and its parking lot operator shall not
                  unreasonably exceed the then prevailing market rates for
                  comparable parking spaces.

            (b)   The Tenant will not park or suffer or permit to be parked, any
                  vehicles owned, leased or controlled by it or by any of its
                  employees, agents or invitees or suffer or permit any loading
                  or unloading of vehicles upon any portion of the Land, except
                  in areas designated for such purposes by the Landlord. The
                  Landlord may, without notice and at any time and from time to
                  time (i) designate parking, loading, and no parking areas;
                  (ii) change or reduce designated parking, paid parking,
                  loading and no parking areas; (iii) cause any parking or
                  loading areas to be shared with other tenants; and (iv) use
                  any parking or loading areas for any reasonable purpose
                  required by the Landlord. From time to time and upon
                  reasonable written notice to the Tenant, the Landlord or its
                  parking lot operator may impose and vary from time to time
                  rates or charges on the Tenant for the use by the Tenant or
                  its employees, agents or invitees of designated parking areas.
                  Whenever requested by the Landlord, the Tenant shall furnish
                  to the Landlord the current licence plate numbers for all
                  vehicles owned, leased or controlled by the Tenant and its
                  employees, agent or invitees.

            (c)   The Tenant will advise the Landlord upon or prior to the
                  Commencement Date, and at such other times as the Landlord may
                  require, as to the greatest number of employees and agents
                  reasonably expected on the Premises at any one time, so as to
                  permit the Landlord to comply with all municipal and other
                  parking bylaws and regulations in respect of the Land,
                  including the Landlord's parking regulations, if any, as
                  determined by it from time to time.

                  suffer the Premises or any part thereof to be used for any
                  other business or purpose. Furthermore, the Tenant shall not
                  at any time use or permit or suffer the Premises or any part
                  thereof to be used for any business or purpose (even if
                  included in the permitted use hereunder) for which the
                  Landlord has granted an exclusive use to another tenant in the
                  Building and notice of which exclusive

                  use has been given by the Landlord to the Tenant, provided the
                  Tenant has not so used the Premises prior to such notice being
                  given. Furthermore, the Tenant shall not carry on the business
                  of auto body or auto or boat repairing, woodworking, fibre
                  glass working, painting or silk screening, automated teller or
                  bank machines or lottery machines. Throughout the whole of the
                  Term, the Tenant shall continuously operate, occupy and use
                  the entire Premises and conduct its business therein pursuant
                  to this Lease.

            (b)   The Tenant shall not commit or suffer to be committed (i) any
                  waste upon the Premises or (ii) any nuisance or other thing
                  which may disturb the quiet enjoyment of any other occupier of
                  premises in the Building; or (iii) any acts or practices which
                  may damage the Building or any improvements on the Land or in
                  the Business Park.

            (c)   The Tenant shall use its best efforts to prevent anything
                  being done on the Premises or the Land which may result in the
                  Land or Building or any part thereof being picketed or
                  otherwise subjected to labour, political or other
                  demonstration or action. In the event of such picketing,
                  action or demonstration, the Tenant shall immediately take all
                  reasonable action and proceedings necessary to cause such
                  picketing, action and demonstration to cease without delay.

            (d)   The Tenant shall use only the business name specified in
                  article 1.1(i) for its business in the Premises and shall not
                  change or permit the change of that name without the prior
                  written consent of the Landlord, which consent shall not be
                  unreasonably withheld so long as the name to which the Tenant
                  changes its business operated in the Premises is the same as
                  the name to which the Tenant changes its other business
                  operations in all its other locations.

            (e)   The Tenant shall comply with all reasonable requests of the
                  Landlord with respect to conservation of energy, recycling and
                  environmental care, and shall pay its Proportionate Share of
                  the costs of acquiring and installing such conservation,
                  recycling and environmental care equipment and systems for the
                  Building.

            (f)   The Tenant shall turn off all lights and other energy-using
                  equipment or systems within the Premises, except where
                  reasonably required to be left on for valid purposes,
                  including security.

            (g)   The Tenant shall not bring onto the Premises or Land, nor
                  discharge nor permit the discharge of any waste, oil or
                  grease, hazardous substance or any deleterious, objectionable,
                  dangerous, radioactive, poisonous or explosive matter or
                  noxious or unpleasant fumes, gases or substance (the
                  "Pollutants") onto the Premises or Land, or into any air,
                  waters, ditches, culverts, drains or sewers on or adjacent to
                  the Premises or Land, and the Tenant shall take all measures
                  necessary to ensure that any effluent or other substance
                  discharged by it is not corrosive, poisonous or otherwise
                  harmful to any sewage disposal works or to the bacteriological
                  process of sewage purification. The Landlord shall be
                  permitted access to the Premises from time to time to test and
                  monitor the effluent from the Tenant's operations and
                  compliance with this section. In addition, the Tenant shall
                  not dispose of, discharge or accumulate or permit to be
                  disposed or, discharged or accumulated on, in or under the
                  Lands any Pollutants. The Tenant shall promptly pay to the
                  Landlord any and all costs incurred by the Landlord in
                  containing, cleaning up, removal and disposal of any materials
                  deemed hazardous or deleterious by the Landlord or and such
                  experts and inspections as it, from time to time, shall
                  employ. These costs are acknowledged to be Additional Rent.
                  This clause and the matters referred to herein may be modified
                  and expanded at the Landlord's sole discretion to comply with
                  requirements imposed by applicable insurers, financial
                  institutions or government authorities. Notwithstanding any
                  other provision of this Lease, the Tenant will comply with all
                  laws and regulations affecting the Lands, specifically
                  including those of an environmental nature. The Tenant will
                  indemnify and save harmless the Landlord of and from the costs
                  of disputing, investigating, remediating, resolving and
                  settling environmental claims against the Lands, or remedying
                  the Tenant's default of this provision.

            (h)   The Tenant shall not bring sharp objects onto the Premises or
                  Land, nor permit any sharp objects which could puncture the
                  skin or constitute a threat of potential harm to persons, and
                  will safeguard, store and dispose of such sharp objects so as
                  to comply with the highest standard of safety and care.

                       UTILITIES AND ADDITIONAL SERVICES

9.1         UTILITIES. The Tenant shall pay as they become due and payable all
rates, charges and other amounts arising for, related to, or incurred in respect
of, services and utilities, including water, fuel, gas communications or other
utility or service and electrical power or energy, heating, ventilation or air
conditioning used upon or in respect of the Premises or any part thereof and for
fittings, machines, apparatus, meters or other things leased in respect thereof,
and for all work and services performed by any corporation or commission in
connection with such utilities or service. Where any such service or utility is
supplied by or through the Landlord, the Tenant shall pay to the Landlord an
amount (the "Charge") which is the total, without duplication, of:

            (a)   the cost incurred by the Landlord for water, fuel, power,
                  electricity, communications, heating, ventilation or air
                  conditioning or other utility or service (the "Utilities")
                  used in or for the Premises or allocated to them by the
                  Landlord;

            (b)   charges imposed in place of or in addition to Utilities as
                  determined by the Landlord; and

            (c)   the Landlord's costs of determining the Charge including, but
                  not limited to, professional, engineering and consulting fees.

                  If the Landlord supplies Utilities, the Tenant shall pay the
Landlord the Charge in advance on demand, which shall be based on estimates of
the Landlord but shall be subject to adjustment within a reasonable time after
the period for which the estimate had been made. The Landlord shall not be
liable for interruption or cessation of, or failure in the supply of Utilities,
services or systems in, to or servicing the Land or the Premises, whether they
are supplied by the Landlord or others, and whether the interruption or
cessation is caused by the Landlord's negligence or not. Upon occupancy of the
Premises, and provided that the Utilities are directly metered by a third party,
the Tenant covenants to transfer all accounts into its name. The Landlord will
disconnect these services as of the Commencement Date, and the Tenant will pay
any and all connection fees if it does not assume the account in its name. If no
separate metering exists for the Premises, the Landlord will, acting reasonably,
allocate the proportionate share of Utilities to each premises in the Building.

9.2         ADDITIONAL SERVICES.  At its option, the Landlord shall have the
exclusive right, by way of Additional Services, to provide or have its
designated agents or contractors provide any janitorial or cleaning services to
the Premises required by the Tenant which are additional to those required to be
provided by the Landlord under this Lease, including any additional services
which the Landlord agrees to provide by arrangement and to supervise the moving
of furniture or equipment of the Tenant and the making of repairs or alterations
conducted within the Premises and to supervise or make deliveries to the
Premises. The Tenant shall pay to the Landlord promptly upon receipt of invoices
therefor from the Landlord or as part of Operating Costs, the Cost of Additional
Services whether the Landlord shall be obligated hereunder or shall elect to
provide them as Additional Services. The Cost of Additional Services charged
directly to the Tenant and other tenants shall be credited in computing
Operating Costs to the extent that they would otherwise have been included. On
request by the Tenant, the Landlord may agree from time to time, in its sole
discretion, to arrange at the Tenant's cost for extra heating, ventilating, and
air conditioning supply, electrical supply or the supply of other services to
the Premises above those normally provided to tenants of the Building or outside
of Building Hours. At its option and at the Tenant's cost as an Additional
Service, the Landlord may install and maintain meters to check the Tenant's
consumption of electricity, water, gas, communication or other utilities or
facilities and provide and maintain garbage or waste receptacles for use of the
Tenant alone or in common with others.

9.3         SECURITY OF PREMISES. Notwithstanding sections 9.1, 9.2, 10.3, and
10.4 of this Lease, the Landlord shall only access the Premises with the consent
of the Tenant, acting reasonably to maintain adequate security of the Premises.

for whom the Tenant may be responsible and in respect of all costs, expenses and
liabilities incurred by the Landlord in connection with or arising out of all
such claims; including the expenses of any action or proceeding pertaining

            Landlord continues to require removal thereof pursuant to this
            Lease;

      (c)   Should the Tenant abandon the Premises or should this Lease be
            terminated before the proper expiration of the Term due to a default
            on the part of the Tenant, then in such event, as of the moment of
            default by the Tenant, all Trade Fixtures and furnishings of the

                             DAMAGE AND DESTRUCTION

16.1        INTERPRETATION. In this Article:

      (a)   "Damage" means damage to property of the Landlord (including but not
            limited to, smoke and water damage and damage that amounts to
            destruction) that:

              1. for the purpose of Section 16.2 results from a peril against
                 which the Landlord is insured and actually receives proceeds of
                 insurance or which the Landlord deems to be Damage; and

              2. for the purpose of Section 16.3 results from any cause, and
                 "Damaged" has a corresponding meaning; and

      (b)   "Usable" means usable by the Tenant for the purpose contemplated by
            this Lease.

16.2        DAMAGE TO THE PREMISES.

      (a)   Subject to Section 16.3, if there is Damage the Landlord shall
            repair or reconstruct the Damage promptly. If part or all of the
            Premises is not Usable because of the Damage, Rent shall abate in
            the proportion that the Floor Area of the part of the Premises that
            is not Usable is to the Floor Area of the whole of the Premises,
            from the date of the Damage until the earlier of:

              1. the date when the whole of the Premises is Usable again; or

              2. thirty (30) days after substantial completion of the repair of
                 the Damage.

      (b)   When the Landlord notifies the Tenant that it has completed enough
            repair of the Damages to enable the Tenant to start the Tenant's
            work, as set out in Schedule "B " the Tenant shall complete the
            Tenant's work and re-open the whole of the Premises for business as
            soon as possible but in any case within thirty (30) days after the
            Landlord's notice. No capital allowance, inducement to lease, or
            other payment that was made to the Tenant at the time of, or in
            connection with the original construction of the Premises shall be
            payable by the Landlord to the Tenant.

      (c)   Notwithstanding subsections (a) and (b), if the Premises are not
            usable for a period of 30 days, and the Landlord is unable to
            provide comparable space to that of the Premises, the Tenant may
            terminate this Lease by giving notice to the Landlord within 10 days
            after the expiry of the said 30 day period.

16.3        DAMAGE TO OR EXPROPRIATION OR CONDEMNATION OF THE LANDS.

      (a)   Despite anything else in this Lease, if:

              1. more than thirty-five percent (35%) of the Floor Area of the
                 Building is Damaged, expropriated or condemned whether or not
                 the Premises are Damaged, expropriated or condemned; or

                 is Damaged, expropriated or condemned or more than fifty
                 percent (50%) of the Floor Area of the Building is Damaged,
                 expropriated or condemned whether or not the Premises are
                 Damaged, expropriated or condemned,

            the Landlord may, by written notice to the Tenant within ninety (90)
            days after the Damage, expropriation or condemnation, terminate this
            Lease, effective thirty (30) days after the notice, and all Rent
            will abate as of the effective date of the termination.

      (b)   If the Building or part thereof shall be damaged or destroyed and
            such damage or destruction shall, in the opinion of the Landlord
            reasonably arrived at, materially interfere with the enjoyment of
            the Premises by the Tenant, the Rent in respect of the Premises
            shall abate in proportion to such interference during the period

                                 RIGHT OF ENTRY

purchasers, lessees or mortgagees, and to enter the Premises during normal
business hours or at such other times mutually agreed between the Landlord and
the Tenant to make such repairs as the Landlord may deem necessary or desirable,
and the Landlord shall be allowed to take all material into and upon the
Premises that may be required therefor without the same constituting an eviction
of the Tenant in whole or in part and the Rent reserved shall in no way abate by
reason of loss or interruption of business of the Tenant or otherwise while
repairs are being made. During the six (6) months prior to the expiration of the
Term, the Landlord may place upon the Premises reasonable notices "To Let" or
"For Lease". The Tenant shall permit such notices to remain thereon without
hindrance or molestation. The Landlord may at any time within six (6) months
before the end of the Term enter the Premises and bring others at all reasonable
hours for the purposes of offering the Premises for rent. If the Tenant or the
Tenant's representative shall not be present to open and permit an entry into
the Premises, at any time, when for any reason an emergency or reasonably
apprehended emergency shall exist or be contemplated, the Landlord or its agent
may enter the same by a master key, or may forcibly enter the same, provided
reasonable care is exercised without rendering the Landlord or such agent liable
therefor, and without in any manner affecting the obligations and covenants of
this Lease. Nothing herein contained however, shall be deemed or construed to
impose upon the Landlord any obligation, responsibility or liability whatsoever,
for the care, maintenance or repair of the Premises or any part thereof except
as otherwise herein specifically provided.

Tenant of any default, breach or non-observance by the Tenant or the Landlord at
any time or times in respect of any covenant, proviso or condition herein

<PAGE>

                                      -27-

registration of a short form of this Lease or any instrument in respect of it,
the Tenant will provide the Landlord a discharge of such a document to be filed

23.13 OBLIGATIONS AS COVENANTS. Each obligation of any party hereto, expressed

pursuant to its terms may be executed in counterparts and signed copies sent by

23.18 SUBLEASE. Subject to the terms and conditions of this Lease and including,
without limitation, the covenants of the Landlord herein, the Landlord and the
Tenant acknowledge that the Landlord is leasing the Premises as part of the
property (being the Land) leased in a head lease (the "Head Lease") from the
registered owner of the Land on which the Premises are located, being originally
George Biely and now Geraldine Biely, Arthur Fouks and Hershey Porte, Executors
of the Will of George Biely, Deceased, which was registered at the New
Westminster Land Title Office February 8, 1994 under registration number
BH43162, and therefore this Lease by the Landlord to the Tenant is in fact a
sub-lease of the Premises. The Landlord covenants and agrees with the Tenant to
pay all rent and additional rent due under the Head Lease as and when due, and
to perform all of the Landlord's covenants and obligations as the tenant in the
Head Lease. The Landlord further covenants and agrees with the Tenant to enforce
for the benefit of the Tenant the covenants and obligations of the head landlord
under the Head Lease with the intent that the benefit of such covenants and
obligations extend to the Premises to be enjoyed by the Tenant. In any case
where the Landlord reserves the right to enter the Premises pursuant to this
Sub-Lease, such right shall enure to the benefit of the head landlord under the
Head Lease as well as the Landlord. The Tenant covenants and agrees to be bound
by the terms and conditions contained in the Head Lease.

23.19 OBLIGATION OF THE FUND. This Agreement is not personally binding upon and
resort shall not be had nor shall recourse or satisfaction be sought from the
private property of any of the unitholders of Investors Real Property Fund ("the
Fund"), trustees, officers, directors, employees, or agents of the trustee or
manager of the Fund, it being intended and agreed that only the property of the
Fund shall be bound by this Agreement. Except to the extent set out in this
Lease, the obligations of the Landlord pursuant to this Lease are joint and
several.

IN WITNESS WHEREOF the parties have executed this Lease as of the date first
above written, and in the case of each corporate party its seal was affixed in
the presence of its duly authorized Officers.

Wayburne Drive will be in a campus like setting with large areas of open green
space. Groups of Western Red Cedars and Douglas Firs will frame the buildings
while directing prime views out to the North Shore Mountains. Raywood Ash trees
line Canada Way and Red Maples alone Wayburne Drive offer spectacular fall
colour. Flowering Japanese Cherries are planted in double row in the center of
the visitor parking court and around the perimeter. Accessible walkways
interconnect the buildings, outdoor use areas and bus stops at Canada Way.
Bicycle parking is provided at building entrances for visitors. The main
entrances are framed by west-coast plantings of Vine Maples, Pacific Dogwood,
Rhododendrons, ferns and other massive plants. The Canada Way entrance features
an outdoor plaza, which doubles as a sunny outdoor sitting area for employees
and visitors and features a focal water element. Terraced gardens with boulders,
low walls, low maintenance plantings and columnar Hornbeam tress flank the
buildings and enhance the park like setting.

STRUCTURAL

Sub-Structure

The foundation design for Canada Way Phase 2 will be based on the Geotechnical
report prepared by Cook Pickering and Doyle Ltd. dated January 3, 1991 and
November 25, 1998.

The building foundation will consist of strip and pad footings. Strip footings
will be a minimum of 400-mm wide and mounded at least 500-mm below grade to
prevent any frost action that may occur.

The slab-on-grade will be underlain by a drainage layer, which will consist of a
minimum of 150 mm of clean granular fill. This drainage layer and the footing
drains around the perimeter of the basement will connect to the storm drainage
system.

The project will have a separate 12.5kV (high voltage) underground electrical
service from BC Hydro to the main electrical room below Building A. The main
electrical room includes a 2500/3300 kVA transformer converting the high voltage
to 600/347V - 3PH - 4 wire for distribution.

Power Distribution

Power is distributed to sub-electrical rooms in the parking below Buildings B
and C at 347/600V.

In each building, transformers in the floor electrical rooms will supply
120/208-Volt receptacle power. There is one 120/208V-panelboard fed from its own
transformer on each floor located in the two floor electrical rooms for floors
2, 3, and 4. Floor 5 has a single electrical room. System Capacity and wall
space is provided in each electrical room for a second transformer and panel.
Transformer capacity for tenant 120V power is approximately 2.8 Watts per square
foot allowing for a 1.5 non-linearity factor (without the non-linearity factor
the capability is approximately 4.0W/ft2). The non-linearity factor deals with
the expected high density of PC computer usage.

120/208 Volt and 347/600-Volt distribution centers and panelboards are 3 phase,
4 wire with full capacity solid neutral complete with bolt on, thermal-magnetic
molded case breakers. Generally panelboards will provide circuits for
connections to devices located only on the same floor as the panelboard. This
design uses series rated circuit breakers for fault current reduction in
accordance with the requirements of the Canadian Electrical Code.

A separate series of 120/208 Volt panels are provided to feed the fan coil
units. These panels are located, one per electrical room and are all fed from
a separate transformer in the building main electrical room.

<PAGE>

600V power is used to feed larger mechanical loads directly. The 347V is used to
feed fluorescent light throughout.

<PAGE>

Telephone and CATV

A new underground BC Telephone Co. Service will be provided to a main Telephone
room located below building A. An extra service duct is provided to enable
installation of future alternative signal carriers. The telephone service ducts
will also include the main CATV service cable. Sub-main telephone rooms are
provided below each of Building B and C.

The sub-main telephone rooms are connected to telephone closets in each building
located two per floor via feeder conduits. Additional empty feeder conduits
will be provided to allow the future installation of alternative communication
technology.

A zone distribution conduit system or cable tray is not provided. A main
telephone service conduit from the nearest base building telephone closet to the
tenants telephone switch is to be provided by each tenant.

Lighting

Lighting energy use will meet or extend the requirement of ASHRAE Standard 90.
Generally the lighting system will provide open office lighting to meet the
illumination levels suggested by the illuminating Engineering Society of North
America (IES) for areas using VDTs (Video Display Terminals).

The main luminaire will be 20" x 48" to fit into 60" boiler.

Outside air will be supplied to the building by an air unit located within the
rooftop mechanical room. This unit will be used that will sense the failure of
the "Pathway" circuits and will trip the battery packs.

All non-incandescent lighting will be run at 347V. Most circuits will run via
the low voltage relays with exceptions for lighting in the electrical rooms and
some service rooms where the lighting will be line voltage switched. The
"Pathway" lights on each floor will be left on at all times; these will function
as Security lights as well.

All interior and exterior lighting except those luminaires on "Pathway" will be
controlled by relays in a low voltage lighting control system. The system will
consist of relays panels located beside each lighting panel. A centrally located
electronic time clock will provide for central lighting control.

Exterior lighting will use Metal Halide or compact fluorescent sources with
lighting levels suitable to the usage.

<PAGE>

Fire Alarm System

The buildings will have a fully supervised, zone fire alarm system that will use
the sprinkler system as primary detection with enunciator panels in each lobby.
