2.a  The Landlord hereby demises and leases to the Tenant the Leased Premises

carrying out the Tenant's business provided it complies with all of its
obligations hereunder (for greater certainty no Rent will be payable until the

2.b  Notwithstanding Section 2.1 herein:

     (i)      if the Landlord and the Tenant, acting reasonably, agree that the
              Landlord's Work required to be completed by November 1, 1997 has
              not been completed 
<PAGE>
 
              by that date and the basement, main, fourth and fifth floors of

              Building have not otherwise been delivered to the Tenant in vacant
              and gutted condition, other than by reason of delays caused by the
              Tenant or Unavoidable Delay, then the Tenant shall have the right,
              exercisable by 12:00 p.m. on October 31, 1997 to terminate this

              other than by reason of delays not caused by the Tenant or
              Unavoidable Delay, then the Fixturing Commencement Date for that

              that the Landlord delivers that portion of the Leased Premises to

              for each month until that portion of the Leased Premises is
              delivered to the Tenant in vacant and gutted condition and the
              Commencement Date for that portion of the Leased Premises shall be
              extended accordingly but in no event shall the expiry date of this
              Lease be extended. Such amounts may be offset by the Tenant
              against Basic Rent payable for that portion of the Leased Premises
              for the third month of the Term;

     (iii)    immediately upon delivery of any portion of the Leased Premises to

              Landlord has fulfilled its obligation to deliver to the Tenant

              and accepting that portion of the Leased Premises as so delivered;

     (iv)     if any of the Landlord's Work is not completed by the dates set
              out in Schedule "A" or if any of the Building renovations are not
              completed by the dates set out in Section 3.4, by reason of delays
              not caused by the Tenant or Unavoidable Delay, then the Tenant
              shall give written notice of the same to the Landlord and, upon
              confirmation that the Landlord is in receipt of such notice, the
              Tenant shall then be entitled to complete the Landlord's Work and
              the Building renovations at a reasonable cost and the Landlord
              shall reimburse the Tenant for its out-of-pocket costs in

            seismic upgrades regardless of the leasehold improvements installed
            by either the Tenant or the Landlord to the first through fifth
            floors of the Building. Should the Tenant convert all or a portion
            of the basement of the Building for office use purposes during the
            Term or any renewal thereof, any seismic upgrades required shall be
            made at the sole cost and expense of the Landlord; and

     (vi)   should the Landlord be responsible for constructing any leasehold

Landlord's prior written approval of the location of the same, which approval
shall not be unreasonably withheld or delayed. No Rent shall be payable by the
Tenant to the Landlord with respect to such use of the roof. The Landlord shall
have the right, at any time during the Term upon giving notice of the same to
the Tenant, and acting reasonably, to relocate such equipment at the Landlord's
cost. The Tenant shall be solely responsible for the cost of any direct increase
in Operating Expenses for the Building attributable to the maintenance and use
of such equipment; such costs shall be deemed to be payable by the Tenant to the
Landlord as Additional Rent and such costs shall not be included in the annual
cap on increases in Operating Expenses set out herein.

3.g  The Landlord shall provide to the Tenant, during the Term, exclusive use of
sixteen (16) parking spaces on a month to month basis at no charge to the

notice from the Landlord and with no notice in the event of emergency, the
Landlord may make such repairs without liability to the Tenant (excepting the
Landlord's negligence) for any loss or damage that may accrue to the Tenant's
fixtures or other property or to the Tenant's business by reason thereof, and
upon completion thereof, the Tenant shall pay to the Landlord, as Additional
Rent, the Landlord's actual reasonable costs in the circumstances plus ten
percent (10%) for making such repairs, forthwith upon presentation of a bill
therefor.

3.j  The Tenant shall erect, place, use or keep in or upon the Leased Premises
only such awnings, projections, signs, advertisements as are first approved in

3.n  The Tenant shall not do or omit to do or permit to be done anything upon or
in respect of the Leased Premises, the doing or omission of which (as the case
may be) may 
<PAGE>
 
increase the hazard of fire or liability of any kind or which may increase the
premium or invalidate the policy of any insurance required to be maintained
hereunder. The cost of any increase in any policy of insurance required to be
maintained by the Landlord hereunder attributable to the Tenant shall be the
sole responsibility of the Tenant and the Tenant shall pay to the Landlord, as
Additional Rent, the amount by which such insurance premiums shall be so
increased.

3.o  At the expiration of the Term or any renewal thereof, and only if the
Tenant is not in material default under any of the terms of this Lease, the
Tenant shall have the right, but not the obligation, to remove from the Leased
Premises any leasehold improvements which were installed with the approval of
the Landlord. The Tenant shall in such removal do no damage to the Leased
Premises or in such case shall immediately make good any damage which may be
occasioned to the Leased Premises and restore the same to such condition as

right at all reasonable times and from time to time, to enter the Leased
Premises upon reasonable notice to the Tenant identifying the nature and scope
of the work to be performed, except in cases of an emergency or perceived
emergency when no notice shall be required to be given to the Tenant, for the
purposes of making such inspections, repairs, alterations, and improvements as
the Landlord may be required to make by law and for purposes of the Landlord
carrying out its obligations hereunder without compensation or responsibility to
the Tenant and for such purposes, if necessary, to enter into, pass through,
work upon and attach scaffolds and other temporary structures to the Leased
Premises. Provided that the Landlord shall use reasonable efforts in exercising
its rights under this Section so as to minimize any interference with the
Tenant's business and use of the Leased Premises, the Tenant shall not have any
right to object to nor any right to any claim of damages or any reduction or
abatement of Rent in respect of the exercise of any of the Landlord's rights
under this Section. It is further understood that the exercise by the Landlord
of its rights under this Section shall not be deemed to be a breach of any
covenant of quiet enjoyment or any other covenant contained in this Lease.

           the rent payable by the sublessee or occupant to

         the Tenant and the Rent payable by the Tenant to the Landlord
         hereunder after deducting lease commission, advertising and re-

  provisions of this  Article 5.

modified or unmodified, confirming the rental payable hereunder and the state of
the accounts between the Landlord and Tenant, the existence or non-existence of
defaults, and any other matters pertaining to this Lease as to which the
Landlord shall request a certificate.  If the Tenant fails to do so within seven
days after the Tenant receives the form of certificate, the Tenant hereby
irrevocably and conclusively authorizes the Landlord to complete, execute, and
deliver the certificate for, on behalf of, in the name of, and as agent of, the

Lease or any interest of the Landlord hereunder, and to the extent that such
purchaser or assignee has assumed the covenants and obligations of the Landlord
hereunder, the Landlord shall, without further written agreement, be freed and

way of the parties insured thereby shall not prevent recovery by any party
thereby insured who is innocent of such act or breach.

            actions, damages, claims, losses, costs, fines, penalties, and
            expenses whatsoever (including all legal and consultants' fees and
            expenses and the cost of remediation of the Leased Premises) arising
            from or in connection with:

            (1)   any breach of or non-compliance with the provisions of this
                  paragraph by the Tenant; or

            (2)   any release or alleged release of any Hazardous Substance or
                  Hazardous Substances at or from the Leased Premises during the
                  Term or any renewal thereof related to or as a result of the
                  use and occupation of the Leased Premises or any act or
                  omission of the Tenant or any person for whom it is in law
                  responsible.

     The obligations of the Tenant under this Section 7.8 shall survive the
     expiry or earlier termination of this Lease.

7.i      The Landlord represents and warrants to the Tenant, to the best of its
knowledge without having made due inquiry, that the Leased Premises and the
Lands do not contain Hazardous Substances, and:

     (i)    have not been used for the sale, storage, manufacture, disposal,
            use, or any other dealing with any Hazardous Substances;

     (ii)   comply in material respects with all applicable federal, provincial
            and municipal environmental, health and safety statutes and
            regulations; and

     (iii)  do not contain PCB's, urea formaldehyde or asbestos.

The Landlord shall indemnify the Tenant and its directors, officers, employees,
agents, successors, and assigns from any and all liabilities, actions, damages,
claims, losses, costs, fines, penalties, and expenses whatsoever (including all
legal and consultants' fees and expenses and the cost of remediation of the
Leased Premises) arising from or in connection any breach of the representations
and warranties contained in this paragraph and from the release or placement of
any Hazardous Substances on the Lands prior to the Commencement Date.  The
obligations of the Landlord under this Section 7.9 shall survive the expiry or
earlier termination of this Lease.

                            DAMAGE AND DESTRUCTION

8.a      Subject to Section 8.2, if during the Term, the Leased Premises or any
improvements or part thereof shall be damaged or destroyed by fire or other
casualty, the damage to the Leased Premises or the said improvements shall be
repaired or replaced by the Landlord with reasonable diligence at its sole cost
and expense, provided that the Tenant shall not have any right to any reduction
or abatement of Rent in respect of the Tenant's carrying out its obligations
under this Section.

8.b      If the Leased Premises are damaged or destroyed by any cause
whatsoever, and if, in the opinion of the Landlord's independent professional
architect or engineer, acting reasonably, the Leased Premises cannot be rebuilt
or made fit for the purposes of the Tenant within one hundred and eighty (180)
days of the damage or destruction, (such assessment to be made and delivered to
the Tenant within thirty (30) days) of such damage or destruction, then either
the Landlord or the Tenant may, at its option, determine this Lease by giving to
the other party, within ninety (90) days of such damage or destruction, notice
of termination, and thereupon all Rent and any other payments for which the
Tenant is liable under this Lease shall be apportioned and paid to the date of
such damage and the Tenant shall immediately deliver up possession of the Leased
Premises to the Landlord.


                                  ARTICLE 9. 
                                    DEFAULT


9.a      If the Tenant:

     (i)  fails or neglects to make any payment due to the Landlord or any other
          person hereunder within five (5) business days after the Landlord
          gives written notice that the payment is overdue; or

     (ii) fails or neglects to cure any default of any of the other terms,
          covenants, agreements or conditions herein on its part to be observed,
          kept or performed, within ten (10) business days after the Landlord
          gives written notice of such default,

then in each such event, the Landlord may, by written notice to the Tenant,
forthwith terminate this Lease without entry upon the Leased Premises, and all
rights and interests of the Tenant under this Lease and all rights of any
persons claiming by, through or under the Tenant, shall thereupon cease and all
Rent then due shall forthwith become due and be payable to the Landlord.

9.b      Notwithstanding the ten (10) business day time period set out in
Subsection 9.1(b):
<PAGE>
 
     (i)   whenever the health or safety of any person or property whether on or
           off the Leased Premises is in jeopardy or the Landlord's or Tenant's
           interest in the Leased Premises or any portion thereof is in jeopardy
           or made liable to any lien or charge, the Landlord may in the notice
           of default given pursuant to Subsection 9.1(b) require that the
           default be cured within any period less than ten (10) business days
           and in such case Subsection 9.1(b) shall be deemed to refer to such
           shorter period; and

     (ii)  if a default in respect of which notice is given pursuant to
           Subsection 9.1(b) cannot with due diligence be cured within ten (10)
           business days or such shorter period as the Landlord may have
           specified in the notice (the onus of proving the same being upon the
           Tenant), and the Tenant:

           (1)   within five (5) business days after receipt of such notice,
                 notifies the Landlord of such inability and of the schedule for
                 curing the default which the Tenant proposes to follow,
                 including an estimated completion date;

           (2)   immediately commences and diligently carries out to completion
                 all acts necessary to cure such default; and

           (3)   keeps the Landlord informed of each delay anticipated or
                 experienced by the Tenant which is likely to further delay the
                 cure of such default,

         then the Landlord shall refrain from exercising its rights under
         Section 9.1 in respect of such default.

9.c      The Tenant covenants that if:

     (i)    any proceedings under the Bankruptcy Act of Canada or any other
            statute of similar purport be commenced against the Tenant or an
            assignee of the Lease; or

     (ii)   the Tenant or any assignee of the Lease is adjudged insolvent or
            makes an assignment for the benefit of its creditors or otherwise
            takes the benefit of any statute for the benefit of insolvent
            debtors; or

     (iii)  a writ of attachment or execution is levied on the leasehold estate
            hereby created or any property of the Tenant or any assignee of the
            Lease upon the Leased Premises and is not released or satisfied
            within fourteen (14) days thereafter; or

     (iv)   a receiver, receiver-manager, trustee, sequestrator or liquidator is
            appointed in
<PAGE>
 
            any proceeding or action with authority to take possession or
            control of the leasehold interest of the Tenant or any assignee of
            the Lease, the Leased Premises or any portion thereof or the
            business conducted thereon by the Tenant or any assignee of the
            Lease, and such appointee is not discharged within a period of
            thirty (30) days after its appointment; or

     (v)    any sale, transfer, assignment, sublease or parting of possession
            occurs which is contrary to Article 5 herein; or

     (vi)   any resolution is passed or other step taken for the winding-up,
            liquidation or other termination of the corporate existence of the
            Tenant,

then each such event shall be deemed to constitute a breach of this Lease by the
Tenant and shall, at the election of the Landlord, by written notice, but
without entry or other action by the Landlord, entitle the Landlord to terminate
this Lease immediately upon the sending of such notice and all rights and
interests of the Tenant under this Lease and all rights of any persons claiming
by, through or under the Tenant, shall thereupon cease and the full amount of
the current months' and next ensuing three (3) months' Rent shall forthwith
become due and be payable to the Landlord.


                                  ARTICLE 10.
                          TERMINATION, REMEDIES, ETC.

10.a     When this Lease expires, is terminated or forfeited or when a surrender
of this Lease is accepted, the Tenant shall immediately:


     (i)  execute and deliver to the Landlord a deed or other document in form
          satisfactory to the Landlord, acting reasonably, conveying and
          surrendering to the Landlord all right, title and interests of the
          Tenant to the Leased Premises and all other  improvements thereon; and

     (ii) re-deliver to the Landlord vacant possession of the Leased Premises in
          a neat and clean condition, in accordance with the terms outlined in
          Section 3.15, with improvements not required to be removed therefrom,
          in the same condition in which they are required to be maintained
          hereunder,

and the Landlord, without further notice to the Tenant, shall have the right to
immediately enter the Leased Premises and take possession thereof with or
without process of law, to remove all personal property therefrom and all
persons occupying the Leased Premises or to use all necessary force therefor,
and in all respects to take the actual, full and exclusive possession of the
Leased Premises as of the Landlord's original estate, without incurring any
liability to the Tenant or to any person occupying or using the Leased Premises
for any damage 
<PAGE>
 
caused or sustained by reason of such termination, forfeiture, surrender, entry,
removal, use or taking, subject to Section 3.15.

10.b     Notwithstanding termination or forfeiture of this Lease, the Tenant
shall be liable to the Landlord for the amount of Additional Rent, Taxes and
other charges and interest thereon payable by the Tenant for the balance of the
Term as if such termination or forfeiture had not occurred, less the actual
payments on account of such charges and interest hereafter received by the
Landlord and applicable to the balance of the Term following deduction by the
Landlord of costs of re-entry, making the Leased Premises leasable and renting
the same and the Landlord shall make commercially reasonable efforts to mitigate
the losses.

10.c     The Tenant expressly waives service of any notice of intention of the
Landlord to re-enter the Leased Premises following termination, forfeiture or
surrender or to institute proceedings for repossession thereof.

10.d     Should the Landlord terminate this Lease, the Landlord may make such
alterations and repairs as may be necessary in order to relet the Leased
Premises and may relet, as agent of the Tenant, the Leased Premises or any part
thereof for such term or terms (which may be for a term extending beyond the
Term of this Lease) and at such rent and upon such other terms and conditions as
the Landlord in its sole and reasonable discretion may deem advisable.  Upon
each such reletting all rent received by the Landlord from such reletting for
the unexpired portion of the Term shall be applied:

     (i)   first, to the payment of any indebtedness other than Additional Rent
           due hereunder from the Tenant to the Landlord;

     (ii)  second, to the payment of any costs and expenses of such reletting,
           including brokerage fees and solicitor's fees and of costs of such
           alterations and repairs;

     (iii) third, to the payment of Additional Rent due and unpaid hereunder;
           and

     (iv)  the residue, if any, shall be held by the Landlord and applied in
           payment of future Additional Rent as the same may become due and
           payable hereunder.

If such payments received from such reletting during any month are less than
that to be paid during that month by the Tenant hereunder, the Tenant shall pay
such deficiency to the Landlord.  Such deficiency shall be calculated and paid
monthly.  No such re-entry or taking possession of the Leased Premises by the
Landlord shall be construed as an election on its part to terminate this Lease
unless a written notice of such intention is given to the Tenant.
Notwithstanding any such reletting without termination, the Landlord may at any
time thereafter elect to terminate this Lease for such previous breach.
<PAGE>
 
10.e     Without prejudice to any other remedy of the Landlord, any money
payable by the Tenant to the Landlord hereunder, including Additional Rent,
shall be paid together with interest at two (2%) percent per annum above the
Prime Rate of interest thereon calculated daily and compounded monthly from the
date the said money becomes payable by the Tenant to the Landlord as Additional
Rent until paid and shall be collectible as rent.

10.f     If the Landlord shall consider it desirable to retain the services of a
lawyer or any other person reasonably necessary for the purpose of assisting the
Landlord in enforcing any of its rights hereunder in the event of default on the
part of the Tenant, it shall be entitled to collect from the Tenant the cost of
all such services as if the same were Additional Rent.

10.g     If the Tenant fails to observe or perform any of its covenants or
obligations hereunder, then notwithstanding that the Landlord may have given the
Tenant notice of such default or that the Tenant may be purporting to cure such
default, the Landlord may, but shall not be required to, cure the default and
may enter upon the Leased Premises for such purpose.  The Landlord shall not be
liable or in any way responsible for any loss, expense, inconvenience, annoyance
or damage resulting to the Tenant or any other person on account thereof.  No
action taken by the Landlord pursuant to this Section 10.7 shall be, or be
construed to be, a termination of the Lease, a waiver of any default by the
Tenant, or as a waiver of any other rights of the Landlord hereunder.  Provided
that if the Landlord shall suffer or incur any damage, loss or expense by reason
of any failure of the Tenant to observe or perform any of its covenants or
obligations hereunder, then the Landlord shall have the right to collect the
cost or amount of any such damage, loss or expense from the Tenant as Additional
Rent, payable as provided herein.

10.h     The remedies of the Landlord set forth in this Lease are in addition to
those permitted or conferred by law and the Landlord may exercise all of its
rights and adopt all such remedies separately or cumulatively as it sees fit.
No such remedy shall be deemed to be exclusive of any other remedy or to
preclude exercise of any right.

10.i     If the Landlord, being entitled so to do, levies distress against the
goods and chattels of the Tenant, such force as may be deemed necessary for the
purpose and for gaining admission to the Leased Premises may be used without the
Landlord being liable for any action in respect thereof or for any loss or
damage occasioned thereby and the Tenant hereby expressly releases the Landlord,
its employees and agents from all action, proceedings, claims or demands
whatsoever for or on account or in respect of any such forcible entry or any
loss or damage sustained by the Tenant in connection therewith.

10.j     If the Tenant does not exercise the Option to Renew provided in Article
12 below and notifies the Landlord in writing, at least 6 months prior to the
end of the Term, or renewal term, as the case may be, of the date that the
Tenant shall vacate the Leased Premises, then the Landlord shall allow the
Tenant to continue to occupy the Leased Premises for a 
<PAGE>
 
period of up to six (6) months after the expiry of the Term or renewal term, as
the case may be and the tenancy thereby created shall be deemed to be a monthly
tenancy at a monthly rent equal to 115% of the Basic Rent payable during the
last month of the Term or renewal term, as the case may be and the Tenant shall
vacate the Leased Premises on the date specified in such notice. If the Tenant
does not so notify the Landlord, as aforesaid, then, subject to the provisions
of this Lease, the Tenant shall vacate the Leased Premises at the expiration of
the Term or renewal term, as the case may be.

10.k     The Landlord, its servants, agents, contractors and representatives
shall be entitled at all reasonable times upon 24 hours notice to enter upon the
Leased Premises for any of the following purposes:

     (i)   inspecting same;

     (ii)  inspecting the performance by the Tenant of the terms, covenants,
           agreements and conditions of this Lease;

     (iii) carrying out any obligations of the Tenant which the Tenant has
           failed to observe or perform under this Lease;

     (iv)  posting and keeping posted thereon notices of non-responsibility for
           any construction, alteration or repair thereof, as required or
           permitted by any law;

     (v)   exhibiting the Leased Premises to prospective lessees or purchasers;
           or

     (vi)  any other reasonable purpose.

10.l     The Tenant shall allow notices "To Let" to be put and remain on the
Leased Premises in a conspicuous position during the six (6) months prior to the
expiry of the Lease only if the Tenant does not exercise its option(s) to renew
or in the event that the Tenant exercises its reduction option as provided in
Section 13.1 of this Lease during the Term or renewal term, as the case may be,
and shall allow prospective lessees or purchasers to enter and inspect the
Leased Premises during the said period with 24 hours notice.  The Landlord
agrees that any such notices will be immediately removed from the Leased
Premises after the Landlord enters into a binding commitment to lease with a
third party.


                                  ARTICLE 11.
                                    NOTICE


11.a     Any notice to be given under this Lease must be given in writing and
will be sufficiently given by delivering to the Landlord or the Guarantor at the
address written on page 1 of this Lease or to the Tenant if addressed to the
Tenant by registered mail.  Any such notice
<PAGE>
 
will be deemed to have been given or made on the date on which it was delivered.
Any Party may change its address for service from time to time by notice in
accordance with the foregoing.


                                  ARTICLE 12.
                                OPTION TO RENEW


12.a     If the Tenant is not in material default under any of the terms of the
Lease, the Tenant, upon giving written notice to the Landlord not later than six
(6) months prior to the end of the Term, shall have the right to renew this
Lease for two (2) further terms of five (5) years each upon the same terms and
conditions as contained in this Lease, save and except:

     (i)  the calculation of the Rentable Area of the Leased Premises should any
          part of the Leased Premises be surrendered during the Term or renewal
          term, as the case may be, in accordance with Article 13 herein or
          expanded;

     (ii) Basic Rent and any further right of renewal.

The Basic Rent payable during such renewal term shall be at the then current
market rental rates for comparable unimproved Leased Premises, or failing
agreement by the Parties on such market rental rate within sixty (60) days prior
to the expiry of the Term, by arbitration pursuant to the Commercial Arbitration
Act of British Columbia, as amended from time to time, or any like statute in
effect from time to time and the decision of such arbitrator(s) shall be final
and binding upon the Parties.  The cost of such arbitration shall be borne
equally by the Parties.

                               OPTION TO REDUCE


13.a     At any time from and after the commencement of the sixth year of the
Term, the Tenant, upon giving at least six (6) months prior written notice to
the Landlord, shall have the right to reduce the Leased Premises by surrendering
unto the Landlord the fourth and fifth floors of the Building, provided that:

     (i)   the Tenant shall be responsible for all costs and expenses associated
           with converting the Building from single tenant occupancy to multi-
           tenant occupancy as required by the City of Vancouver, including
           without limitation, providing elevator access and a lobby;

     (ii)  the Tenant shall be required to repay, in full immediately upon the
           date of surrender, the unamortized Tenant Improvement Allowance
           attributable to the
<PAGE>
 
           area so surrendered (calculated using a discount rate of 8%) together
           with a penalty of $81,258 plus 3 months' Operating Expenses
           attributable to the area so surrendered; and

     (iii) the Tenant shall execute and deliver to the Landlord all such
           amendments to this Lease and further documents to reflect the
           surrender contemplated by this Article 13 and the amendment of this
           Lease to reflect the multi-tenant occupancy of the Building.

                                   --------


14.a     In consideration of the Landlord leasing the Leased Premises to the
Tenant and the sum of $1.00 now paid by the Landlord to the Guarantor and other
good and valuable consideration (the receipt and sufficiency of which is hereby
acknowledged by the Guarantor), the Guarantor unconditionally agrees to and
covenants with the Landlord to guarantee to the Landlord the full and prompt
payment of all sums, including but not limited to, Rent, Additional Rent and any
and all other sums and charges payable by the Tenant to the Landlord under the
Lease, and the full performance and observance of all of the covenants, terms,
conditions and agreements therein provided to be performed and observed by the
Tenant.


                                  ARTICLE 15.
                            INTERPRETATION/GENERAL


15.a     In the event the Landlord sells, transfers or assigns its interest in
the Leased Premises or any part thereof to a bona fide third party at arm's
length, then so long as the purchaser, transferee or assignee agrees with the
Tenant to assume, observe and perform all of the covenants, conditions and
agreements on the part of the Landlord to be observed and performed in this
Lease in respect of all or the part of the Lands so affected, the Landlord shall
no longer have any duties, covenants and obligations under this Lease and
consequently shall not be liable to the Tenant for the performance of any such
duties, covenants and obligations.

15.b     If the Leased Premises or any part thereof are expropriated or
condemned at any time during the Term, the Landlord shall have no liability to
the Tenant for the Landlord's inability to fulfil any of its covenants herein,
but in each such event the Landlord and the Tenant may seek compensation
separately from the expropriating authority and shall co-operate in seeking such
compensation, and if a joint award of compensation is made it shall be divided
as agreed between the Landlord and the tenant and failing agreement either party
may refer to matter to arbitration.

15.c     Time is expressly declared to be of the essence of this Lease and of
each and every term, covenant, agreement, condition and provision hereof and
observance and performance thereof.
<PAGE>
 
15.d     This Lease is made in accordance with the laws of the Province of
British Columbia and is to be construed and interpreted in accordance therewith.
Any action or proceeding arising concerning this Lease may (and if against the
Landlord, shall) be brought in the courts of the said Province and each of the
parties hereto submits and attorns to the jurisdiction of the Province of
British Columbia.

15.e     The Tenant shall observe, abide by and comply with all federal,
provincial, municipal (and all other competent authorities) statutes, laws,
orders, regulations, by-laws, directions, rules and requirements, respecting the
use and occupation of the Leased Premises and the making of any repairs,
replacements, alterations, additions, changes or improvements on the Leased
Premises and shall observe, carry out and comply with any lawful order,
direction, request, requirement and/or notice of authority, commission,
department or officer or any insurance company carrying insurance on the Leased
Premises and to comply with any restrictions or covenants registered against the

and are not to be considered in the construction of this Lease or as in any way
limiting or amplifying the provisions hereof.

15.g     All the obligations on the part of each of the Parties shall be
construed and read as if such obligations are covenants notwithstanding that the
term covenant is not used.

15.h     The language in all parts of this Lease shall in all cases be construed
as a whole and not strictly for nor against either the Landlord or the Tenant.

15.i     Whenever the context so requires, the neuter gender shall include the

and vice versa.

15.j     No condoning, excusing or overlooking by the Landlord of any default,
breach or non-observance by the Tenant at any time or times in respect of any of
the Tenant's covenants and agreements as contained in this Lease and no
acceptance of Additional Rent or other monies payable by the terms of the Lease
by Tenant to the Landlord subsequent to any breach or default hereunder by the
Tenant of any of Tenant's covenants and agreements as contained in this Lease,
shall be taken to operate as a waiver or in any way defeat or affect the rights
of the Landlord under this Lease with respect to such breach or default and the
failure of Landlord from time to time to insist upon strict performance by
Tenant of the Tenant's agreements, terms, covenants and conditions contained in
this Lease shall not be deemed a waiver of any rights or remedies that the
Landlord may have.

15.k     If any term, covenant or condition of this Lease or the application
thereof to any person or circumstance shall, to any extent, be held or rendered
invalid, void unenforceable or 
<PAGE>
 
illegal, it or its application shall be considered separate and severable from
this Lease to such extent and the remainder of this Lease, or the application of
such term, covenant or condition to persons or circumstances other than those as
to which it is held invalid, void, or unenforceable or illegal, shall not be
affected thereby and each terms, covenant or condition of this Lease shall be
valid and enforceable to the fullest extent permitted by law.

15.l     Each of the Parties agrees to do all acts and sign such documents as
may be requested by any of the other Parties in order to give effect to the
terms and intentions expressed in this Lease.

15.m     This Lease and the Schedules attached hereto and forming a part hereof
and the Offer to Lease which forms a part hereof, set forth all the covenants,
promises, agreements, conditions and understandings between the Landlord and the
Tenant concerning the Leased Premises and there are no covenants, promises,

<PAGE>
 
Install bathrooms on basement level
Install glazing at the rear on the main and basement levels, but limited to a

Existing T-bar ceiling will stay and currently hidden wooden ceiling beams will
remain hidden below the T-bar because exposing the ceiling would require
completely new heating, ventilation and air conditioning systems, sprinklers,
electrical system (dramatically increasing rental rates) and sandblasting the
ceiling is impractical with Safeway Canada Ltd. occupying the 26,000 square feet
of the Building presently occupied by it.  The exposed brick walls and wooden
columns will provide a "funky" Yaletown style Building despite the T-bar
ceiling.  Should the Tenant elect to make modifications to the existing T-bar
ceiling, such changes and any related building requirements necessitates by such
change shall be at Tenant's sole cost and expense.
