ARTICLE 4    RENT


4.1 Basic Rent:

The Tenant shall pay to the Landlord, yearly and every year during the Term,
without any set-off, compensation or deduction whatsoever, a Basic Rent in
Canadian dollars as follows:

        (a) from the 1st day February of 1994 to the 30th day of April, 1994
        zero dollars, and


                                      -6-


        (b) from the 1st day of May 1994 to the 31st day of December, 1997
        $52,228.96 annually payable in advance in equal consecutive monthly
        instalments of $4,352.41 on the first day of each and every month during
        such period, and

        (c) from the 1st day of January, 1998 to the 31st day of December, 2001
        $139,223.52 annually payable in advance in equal consecutive monthly
        instalments of $11,601.96 on the first day of each and every month
        during such period.

Basic Rent has been calculated on the basis that the rental rate for the Initial
Premises is $14.00 per annum during the first four (4) years of the Term (except
for the period January 1st, 1994 to March 30, 1994) and for the Premises is
$18.00 per annum during the balance of the Term per square foot of Gross
Rentable Area in the Premises. If there are changes to the Gross Rentable Area
of the Premises, Basic Rent shall be adjusted accordingly.


4.2 Additional Rent:


The Tenant shall pay to the Landlord, during the Term, when due, as Additional
Rent and without duplication:

        (a) that portion of Taxes payable by the Tenant pursuant to section 5.3;

        (b) the Tenant's Proportionate Share of Operating Costs pursuant to
        section 6.1;

        (c) all Additional Service Costs payable by the Tenant; and

        (d) all other amounts payable by the Tenant pursuant to this Lease.

4.3 Payment of Additional Rent:


The Additional Rent specified in subsections 4.2(a), (b) and (c) shall be paid
and adjusted with reference to a fiscal period of 12 calendar months, which
shall be the 12 month period ending on December 31st in each year during the
Term unless the Landlord, by notice to the Tenant, shall from time to time have
selected a fiscal period which ends on a different date (but which shall be a 12
month period except where a shorter broken fiscal period occurs at the
commencement or end of the Term or is necessary to accommodate a change in the
fiscal period made during the Term). From time to time throughout the Term, the
Landlord shall give notice to the Tenant of the Landlord's estimate of such
Additional Rent to be paid by the Tenant during the next ensuing fiscal period.
Each estimate shall be reasonable. Such Additional Rent payable by the Tenant
shall be paid in monthly instalments in advance at the same time as payment of
Basic Rent is due hereunder and shall be based on the Landlord's estimate as
aforesaid. From time to time the Landlord may re-estimate, on a reasonable
basis, the amount of such Additional Rent for any fiscal period in which case
the Landlord shall give notice to the Tenant of such re-estimate and fix new
monthly instalments for the remaining balance of such fiscal period so that,
after giving credit for the instalments paid by the Tenant on the basis of the
previous estimate or estimates, all the Additional Rent as estimated or
re-estimated will have been paid during such fiscal period.

All Additional Service Costs shall be paid by the Tenant within five days after
receipt by it from time to time of invoices from the Landlord specifying the
amounts thereof.


                                      -7-

After the end of each fiscal period referred to in section 4.3, the Landlord
shall deliver to the Tenant a statement of the Landlord as to the actual
Additional Rent payable to the Landlord pursuant to subsections 4.2(a), (b) and
(c) in respect of such fiscal period and a calculation of the amount by which
such Additional Rent payable by the Tenant varies from the aggregate instalments
paid by the Tenant on account of such Additional Rent for such fiscal period.
Within 30 days after the receipt of such statement, either the Tenant shall pay
to the Landlord any amount by which the amount found payable by the Tenant with
respect to such fiscal period exceeds the aggregate of the monthly payments made
by it on account thereof or the Landlord shall pay to the Tenant any amount by
which the amount found payable as aforesaid is less than the aggregate of such
monthly payments.

The Tenant shall have the right, exercisable by notice to the Landlord given
within 30 days after receipt of any statement of such Additional Rent submitted
by the Landlord as aforesaid, to verify the accuracy of any amount shown on any
statement by requiring the Landlord to give to the Tenant appropriate
explanations related to such statement.

In the event of any dispute by the Tenant as to the amount of such Additional
Rent payable, a letter of the Landlord's auditors shall be conclusive.


4.5 Apportionment of Rent:


Rent shall be considered as accruing from day to day hereunder. If it is
necessary to calculate Rent for a period of less than one year or less than one
calendar month, an appropriate apportionment and adjustment on a pro rata daily
basis shall be made. Where the calculation of Additional Rent cannot be made
until after the expiration or earlier termination of this Lease, the obligation
of the Tenant to pay such Additional Rent shall survive the expiration or
earlier termination hereof, and such amount shall be paid by the Tenant to the
Landlord forthwith upon demand. If the Term commences on any day other than the
first day of the month, Rent for such fraction of a month shall be adjusted, as
aforesaid, and paid by the Tenant on the commencement date of the Term.


4.6 No Right of Set-off:


The Tenant expressly waives the benefits of section 35 of the Landlord and
Tenant Act R.S.0 1980, Chapter 232 and any amendments thereto and any present or
future enactment of the Province of Ontario permitting the Tenant to claim a
set-off against Rent for any cause whatsoever.

All Additional Rent shall be deemed to be rent and the Landlord shall have all
rights against the Tenant for default in payment of Additional Rent as for
default in the payment of Basic Rent.


4.8 Interest on Arrears:


If the Tenant fails to pay Rent when due, the Tenant shall pay interest on the
unpaid amount at the Rate of Interest from the date due until the date paid,
without prejudice to and in addition to any other remedy available to the
Landlord under this Lease or at law.


                                      -8-


4.9 Net Lease to Landlord:

        there are separate assessments (or, in lieu thereof, calculations made
        by authorities having jurisdiction from which separate assessments may,
        in the Landlord's opinion, be readily determined) for the Premises for
        tax purposes, the Landlord shall use same for purposes of determining
        the amount payable by the Tenant pursuant to this subsection (a). The
        Tenant shall provide the Landlord with a copy of any separate notices of
        assessment for the Premises which the Tenant has received. If there are
        no such separate assessments or calculations, the Tenant shall pay the
        Tenant's Proportionate Share of all taxes attributable to the
        development provided that if the Landlord acting reasonably determines
        that another method of calculating the Tenant's contribution to Taxes is
        appropriate, such other method shall be used.

        (b) The Tenant shall, in respect of each calendar year included in whole
        or in part within the Term, pay to the Landlord the amount by which
        Taxes are increased above the Taxes which would have otherwise been

        of the Premises being taxed or assessed in support of separate schools.

        (c) Payment by the Tenant of all amounts on account of Taxes shall be
        governed by sections 4.3 and 4.4.

        section 5.1, and the Tenant may postpone any payment payable by it
        directly to a taxing authority (but not to the Landlord) pursuant to
        this Article in each case to the extent permitted by law and if
        prosecuting in good faith any appeal against the imp sition thereof, but
        provided that in the case of a postponement by the Tenant which involves
        any risk of the Development or any part thereof or the Landlord becoming
        liable to assessment, prosecution, fine or other liability, the Tenant
        shall have given security in a form and of an amount satisfactory to the
        Landlord in respect of such liability and such undertakings as the
        Landlord may reasonably require to ensure payment thereof.

        (b) Whenever requested by the Landlord, the Tenant shall deliver to the
        Landlord receipts for payment of all amounts owing by the Tenant
        pursuant to section 5.2 and furnish such other information in connection
        therewith as the Landlord may reasonably require.

be responsible for any loss, damages or costs arising from the failure of such
equipment or systems to perform their function. In addition, the Landlord shall
not be responsible for the failure of such equipment and systems to perform
their function if the number of persons in the Premises at any one time exceeds
a reasonable number or if the electrical load from lights and power in the
Premises is excessive or if such failure results from any arrangement of
partitioning in the Premises or change or alteration thereto or if the window
covering on exterior windows is not kept fully closed while the windows are

location thereof, to employ all personnel and to make all rules and regulations
necessary for the proper operation and maintenance thereof, and to do such other
acts with respect thereto as the Landlord, acting reasonably, shall determine to
be advisable; provided, however, that the Tenant, unless deprived by reasons
beyond the Landlord's control, shall have the use of such of the Building Common

        services of a standard (both as to extent and frequency) as a reasonably
        prudent owner would do having regard to the type and age of the
        Development, the cost of which is to form a part of Operating Costs.
        Such services shall include, but not be limited to, causing periodically

        of the Tenant, although the Landlord shall have the right to elect to
        provide such additional cleaning at the Tenant's expense, as provided in
        subsection (c).

        (b) The Tenant acknowledges that the Landlord will be relieved from its
        cleaning obligation as provided in subsection (a) in respect of any part
        of the Premises to which access is not granted to the person or persons
        retained to perform such work.

        (c) If the Tenant desires any janitor or cleaning services for the
        Premises in addition to those contemplated by subsection (a) and if the
        Landlord from time to time elects, acting reasonably, to provide
        exclusively (either directly or through agents or contractors designated
        by it) such additional services or if the Landlord supervises the moving

        Additional Service Costs shall be paid by the Tenant to the Landlord
        forthwith after demand.

        (d) The Tenant acknowledges that the Landlord shall not be responsible

The Landlord has the right to stop the use of any facilities and the supply of
any services when necessary by reason of accident or during the making of
repairs, replacements, alterations or improvements, in the judgment of the
Landlord necessary or desirable to be made, until the repairs, replacements,
alterations or improvements have been completed to the satisfaction of the
Landlord provided that all reasonable steps shall be taken to minimize any
interference with the Tenant's use and enjoyment of the Premises, both as to the
extent and duration of such interference. The Landlord shall have no
responsibility or liability for failure to operate any facilities or supply any
services when the use of the facility is stopped as aforesaid or when the
Landlord is prevented from using the facility or supplying the service by
strike, or by orders or regulations of any governmental authority or agency or
by failure of the electric current, gas, steam or water supply necessary to the
operation of any facility or by the failure to obtain such a supply or by any

in the Premises anything which would cause any policy of insurance on the
Project or the Development to be subject to cancellation or non-renewal or which
would cause an increase in the cost of any insurance which the Landlord is
obligated by this Lease to maintain. Upon any default by the Tenant which would
result in cancellation or non-renewal or an increased cost which the Tenant does
not pay, the Landlord may, at its option, terminate this Lease on 10 days=

to the cancellation, threatened cancellation or alteration in coverage within 48
hours (or such lesser period as the Landlord acting reasonably may determine,
having regard to the urgency of the situation) after notice to ~he Tenant of
such cancellation or proposed cancellation or alteration, the Landlord may, (but
shall not be obligated to), without further notice or any liability to the
Tenant or any other occupant of the Premises, enter the Premises arid attempt to

from time to time by the Landlord acting reasonably and of which notice has been
given by the Landlord to the Tenant.

The Tenant acknowledges that the Rules and Regulations, as from time to time
amended or replaced, are not necessarily of uniform application but may be
waived in whole or in part in respect of other tenants without affecting their
enforceability with respect to the Tenant and the Premises, and may be waived in
whole or in part with respect to the Premises without waiving them as to future
application to the Premises, and the imposition of such Rules and Regulations
shall not create or imply any obligation of the Landlord to enforce them.


                                      -14-

In any conflict between a provision of this Lease and any of the Rules and

        make, erect, alter or install any Leasehold Improvements or other
        alterations or installations to the Premises (the AWork@).

        (b) If the Tenant wishes to have any Work done in the Premises, the
        Tenant shall apply for the Landlord's consent and furnish such plans,
        specifications and designs as shall be necessary to fully describe the
        Work. The Landlord's consent thereto shall not be unreasonably withheld
        or delayed; provided that, without limitation, any refusal to grant
        consent based on grounds that such Work is not in compliance with the
        Building Standard or that the Tenant has not posted security with the
        Landlord shall be conclusively deemed not to be an unreasonable
        withholding of consent.

        (c) Subject to the Landlord's consent having been obtained and the
        Landlord's reasonable requirements (including the posting of reasonable
        security, if requested) being met, the Landlord recognizes the right of
        the Tenant to install such interior partitions and other Leasehold
        Improvements as are necessary or appropriate to its use and occupancy of
        the Premises.

        (d) Any Work shall, if the Landlord so elects, be performed by the
        Landlord or by contractors who have been designated by the Landlord and
        who have contracted directly with the Tenant and agreed to carry out
        such Work in a good and workmanlike manner and at a cost to the Tenant
        equal to the Landlord's or contractor=s cost plus 10% for supervision
        and 10% for profit. In the absence of any such election by the Landlord,
        such Work may be performed by contractors retained by the Tenant
        pursuant to written contracts which have been approved by the Landlord
        (such approval not to be unreasonably withheld) and are subject to all
        reasonable conditions which the Landlord imposes. In either event, the
        Landlord shall have the right to inspect such Work and require any Work
        not being properly done to be corrected, and to approve on a reasonable
        basis (which may include considerations involving trade union
        affiliations or the lack of them and work jurisdiction, where in the
        opinion of the Landlord there is a risk of labour disputes which might
        adversely affect the Landlord) the contractors, tradesmen or the
        Tenant's own employees (as the case may be) employed by the Tenant in
        connection therewith.

        within 30 days after the giving of the Landlord's written opinion above
        referred to, and the Tenant shall immediately thereupon surrender the

        the date of such destruction or damage (subject to the payment of Rent
        from the date of such destruction or damage to the date of surrender in
        the same proportion that the part of the occupiable area of the Premises
        fit for occupancy by the Tenant until such surrender is to the total
        occupiable area of the Premises).

        (b) If and whenever all or any portion of the Building is destroyed or
        damaged by reason of any cause (whether or not such portion includes all
        or any part of the Premises) to such extent that:

            (i)    in the Landlord's reasonable opinion to be given to the
                   Tenant in writing within 60 days after the occurrence of such
                   damage or destruction, it is unable to be repaired or rebuilt

            (ii)   the estimated cost (as estimated by the Landlord) of
                   repairing or rebuilding the Building exceeds the proceeds of
                   insurance available to the Landlord for such purpose (or
                   which would have been available if the Landlord had insured
                   in compliance with section 10.1);

the Landlord may terminate this Lease upon not less than 30 days' prior written

                   by the Tenant, Rent shall abate from the date of such
                   destruction or damage to the date of surrender in the same
                   proportion that the part of the occupiable area of the
                   Premises unfit for occupancy is to the total occupiable area
                   of the Premises; and

            (iv)   otherwise Rent shall be apportioned to the date of surrender.


                                      -18-


        (c) If and whenever the Premises are destroyed or damaged by reason of
        any cause and this Lease shall not have been terminated, the Landlord
        shall, with all reasonable diligence, make the repairs specified in
        section 9.1 and the Tenant shall, with all reasonable diligence and in
        compliance with section 8.1, make all repairs to the Premises specified
        in section 9.2 and complete the Premises for occupancy for the purpose
        described in section 7.1 and in compliance with subsection 7.5(b). If as
        a result of any destruction or damage to the Premises which the Landlord
        is obligated to repair pursuant to section 9.1, and which is not the
        fault of the Tenant or those for whom it is in law responsible and which
        does not consist of merely a temporary interruption of or interference
        with any utility, service or access, the Premises are rendered in whole
        or in part unfit for occupancy by the Tenant, then during the period
        commencing on the occurrence of such destruction or damage and ending
        upon the earlier of:

            (i)    the date when both the repairs to the Premises which the
                   Landlord is obligated to make as aforesaid are completed
                   sufficiently to enable the Tenant to commence its repairs,
                   and the Tenant has been allowed a reasonable period of time
                   which is sufficient for the completion by it of the repairs
                   it is obligated to make as aforesaid with due diligence; and

            (ii)   the date upon which no insurance proceeds are available to
                   the Landlord under its loss of rental income insurance
                   coverage in respect of the Premises (other than by reason of
                   the Landlord not carrying the insurance as set out in section
                   10.1);

Rent shall from time to time abate in the same proportion that the part of the
occupiable area of the Premises from time to time rendered unfit for such
occupancy by reason of such destruction or damage is to the total occupiable
area of the Premises.


9.6 No claim by Tenant:

Except in respect of abatement of Rent as provided for in this Article, no claim
for compensation or damages, direct or indirect shall be made by the Tenant by
reason of the loss of use, inconvenience or otherwise arising from the necessity
of repairing any portion of the Development however the necessity may arise so
long as any such repair to be carried out by the Landlord is carried out with
reasonable diligence.

        against loss or damage by perils now or hereafter from time to time
        embraced by or defined in a standard all risks insurance policy;

        (b) boiler and machinery insurance on objects defined in a standard
        comprehensive boiler and machinery policy against accidents as defined
        therein;

        (c) loss of rental income insurance in an amount sufficient to replace
        all Basic Rent and Additional Rent payable under the provisions of this
        Lease for an indemnity period determined by the Landlord;

        personal injury and property damage arising out of all operations in

        (e) such other coverage, or increases in the amount of coverage, as the
        Landlord may consider necessary.

For greater certainty, the Tenant acknowledges that the Landlord is not
obligated to insure Leasehold Improvements in the Premises. The insurance to be
maintained by the Landlord shall be that which would be carried by reasonably
prudent owners of properties similar to the Development, all as from time to
time determined by insurance advisers selected by the Landlord, and whose
opinion shall be conclusive. In the alternative, the Landlord shall have the
option of self-insuring.

Notwithstanding the above, the Tenant acknowledges that the Tenant shall remain
responsible for its negligence and the negligence of all persons for whom it is
at law responsible and that no insurable interest is conferred upon the Tenant
under any of the Landlord's insurance policies and that the Tenant shall have no
right to recover any proceeds thereunder or claim any right or title to such
proceeds.





10.2 Tenant's Insurance:

and such other times as the Tenant is in occupation or possession of the

        liability, which shall include coverage for personal injury, broad
        blanket contractual liability, employer's liability, owner's protective
        liability, all risks Tenant's legal liability, non-owned automobile
        liability, bodily injury, death and property damage, all on an
        occurrence basis with respect to the business carried on in the Premises
        and the Tenant's use and occupancy of the Premises and its use of the
        Common Facilities or of any other part of the Building, with coverage
        for any one occurrence or claim of not less than $5,000,000 or such
        other amount as the Landlord may from time to time reasonably require
        upon not less than 30 days' notice at any time during the Term, which
        insurance shall contain a severability of interest clause and a
        cross-liability clause;

        (b) "all-risks" property insurance covering the Leasehold Improvements
        and other items excluded from the definition of Leasehold Improvements,
        trade fixtures, and the furniture and equipment in the Premises on a
        full replacement basis, with an agreed amount co-insurance clause and
        by-law endorsement and which insurance shall provide that any proceeds
        recoverable with respect to Leasehold Improvements shall be payable to
        the Landlord (but the Landlord agrees to make available such proceeds
        toward the repair or replacement of the insured property if this Lease
        is not terminated pursuant to any other provisions hereof); and


                                      -20-


        (c) insurance against such other perils and in such amounts as the
        Landlord or any mortgagee of the Landlord or the Tenant may from time to
        time reasonably require upon not less than 60 days' notice, such
        requirement to be made on the basis that the required insurance is
        customary at the time in the City of Ottawa for tenants of buildings
        similar to the Building.


10.3 Form of Tenant's Insurance:

All insurance required to be maintained by the Tenant hereunder shall be on
terms and with insurers to which the Landlord has no reasonable objection. Each
policy shall (a) contain a waiver by the insurer of any rights of subrogation or
indemnity or any other claim to which the insurer might otherwise be entitled
against the Landlord or the directors, officers, agents or employees of the
Landlord, (b) name the Landlord and its directors, officers, agents and
employees as additional insureds, (c) be primary, noncontributory with and not
excess of any insurance available to the Landlord and (d) contain an undertaking
by the insurer that no material change adverse to the Landlord or the Tenant
will be made and the policy will not lapse or be cancelled or not be renewed,

the Landlord of the intended change, lapse, cancellation or non-renewal. The
Tenant shall furnish to the Landlord certified copies of the policies of
insurance from time to time effected by the Tenant -and its renewal or
continuation in force, together with evidence as to the method of determination
of full replacement cost of the Tenant's Leasehold Improvements and other items
excluded from the definition of Leasehold Improvements, trade fixtures,
furniture and equipment. If the Landlord reasonably concludes that the full
replacement cost has been underestimated, the Tenant shall forthwith arrange for
any consequent increase in coverage required under section 10.2. If the Tenant
fails to take out, renew or keep in force such insurance, or if the policies
submitted to the Landlord pursuant to the preceding sentence are unacceptable to
the Landlord (or no such policies are submitted within a reasonable period after
request therefor by the Landlord), then the Landlord may give to the Tenant
notice requiring compliance with this section and specifying the respects in
which the Tenant is not then in compliance with this section. If the Tenant does
not, within 72 hours (or such lesser period as the Landlord may reasonably
require having regard to the urgency of the situation), provide appropriate
evidence of compliance with this section, the Landlord may (but shall not be
obligated to) obtain some or all of the additional coverage or other insurance
which the Tenant shall have failed to obtain, without prejudice to any other
rights of the Landlord under this Lease or otherwise, and the Tenant shall pay
all premiums and other costs incurred by the Landlord forthwith upon demand.


10.4 Release of Landlord by Tenant:

The Tenant agrees that neither the Landlord nor its directors, officers, agents,
employees or any others for whom the Landlord is at law responsible shall be
liable to any extent for any personal injury or death of, or loss or damage to
any property belonging to the Tenant or its employees, invitees or licensees or
any other person in, on or about the Development unless resulting from the
actual gross negligence of the Landlord (but only to the extent of such actual
gross negligence). Notwithstanding the foregoing, in no event shall the Landlord
or its directors, officers, agents, employees or any others for whom the
Landlord is at law responsible be liable for (and the Tenant hereby releases the
Landlord and its directors, officers, agents, employees and any others for whom
the Landlord is at law responsible from):

        leak into, issue or flow from any part of the Development or from the
        pipes or plumbing works, including the sprinkler system, thereof, 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 of sprinkler heads, or for any damage caused by anything done
        or omitted by any other tenant;

        (b) any act or omission (including theft, malfeasance or negligence) on
        the part of any. agent, contractor or person from time to time employed

        instruments, papers or other valuables of the Tenant; or

        (d) loss or damage for which the Tenant does or is required to carry
        insurance.

officers, agents and employees against and from any and all expenses, costs,
damages, suits, actions or liabilities arising or growing out of any default by
the Tenant hereunder, and from all claims and demands of every kind and nature
made by any person or persons to or against the Landlord and/or its directors,
officers, agents and employees, for all and every manner of costs, damages or
expenses incurred by or injury or damage to such person or persons or his, her
or their property, which claims or demands may arise howsoever out of the use
and occupation of the Premises by the Tenant or any subtenant or occupant
authorized by the Tenant or by any assignee or sublessee thereof or any of the
above-mentioned or his, her or their servants, agents, assistants, employees,
invitees or other persons entering into the Building to go to the Premises or

        interest therein without the consent of the Landlord which shall not be
        unreasonably withheld. Without limiting the foregoing, it shall
        institute reasonable grounds for any withholding of consent by the
        Landlord that, in the Landlord's opinion, (i) the proposed assignee or
        subtenant does not have a satisfactory financial condition having regard
        to the obligations which it will assume as assignee or subtenant, or
        (ii) the proposed assignee or subtenant is a tenant or subtenant of
        other space in the Project or (iii) the proposed assignee or subtenant
        does not have an established good reputation in the business community,
        or (iv) the proposed assignee or subtenant is a Consulate, Embassy,

        use any part of the Premises for purposes which are not permitted by
        this Lease or which are not acceptable to the Landlord, acting
        reasonably, or which are not compatible with the other businesses or
        activities which are being carried on in the Development or which
        contravene any restriction on use in the Building or (viii) where the
        return to the Tenant on any proposed assignment or subletting is greater
        than the amounts payable by the Tenant hereunder and the Tenant has not
        agreed to pay such excess to the Landlord. The Landlord shall be
        entitled to withhold consent to assign or sublet arbitrarily where it
        exercises its right to termination pursuant to section 11.2.


                                      -22-


        (b) Without limitation, the Tenant shall be deemed to have assigned or
        sublet in any case where it permits the Premises or any portion thereof
        to be occupied by a person or persons other than the Tenant, its
        employees and others engaged in carrying on the business of the Tenant,
        whether pursuant to assignment, subletting, license or other right, and
        shall also include any case where any of the foregoing occurs by
        operation of law and, so often as same shall occur, the Tenant shall
        give notice to the Landlord and the provisions of this section and
        section 11.2 shall apply, mutatis mutandis.

        (c) If the Tenant (or any permitted assignee thereof) is a corporation,
        then the Tenant shall be deemed to have assigned or sublet in any case
        where such number of shares of such corporation or of any parent or
        affiliate of such corporation are issued or transferred, whether by
        operation of law or otherwise, so as to result in a change in the
        effective control of such corporation then, and so often as such a
        change of control shall occur, the Tenant shall give notice to the
        Landlord and the provisions of this section and section 11.2 shall
        apply, mutatis mutandis.

        (d) The Landlord shall also have the right of approval prior to any

        sublet, as the case may be, but only upon the terms set out in the offer
        submitted to the Landlord pursuant to section 11.2 and not otherwise.

        Tenant's request for consent and only upon any assignee or subtenant
        entering into an agreement directly with the Landlord and in a form
        satisfactory to the Landlord acting reasonably to perform, observe and
        keep each and every covenant, proviso, condition and agreement in this
        Lease on the part of the Tenant to be performed, observed and kept,
        including payment of Rent.

        (f) The Tenant shall have the right to assign or sublet to a corporation
        affiliated (as that term is defined in the Ontario Business Corporations
        Act) with the Tenant without the consent of the Landlord (and the
        provisions of subsection 11.2(b) shall not apply), provided that the
        Tenant has first given notice to the Landlord and further provided that
        the Tenant and its affiliate have first entered into an agreement
        directly with the Landlord in a form satisfactory to the Landlord acting
        reasonably, whereby the affiliate agrees to perform, observe and keep
        each and every covenant, proviso, condition and agreement in this Lease
        on the part of the Tenant to be performed, observed and kept, including
        payment of Rent and whereby the Tenant and the affiliate agree to remain
        affiliated to one another, a breach of which agreement would constitute

        section shall be paid by the Tenant forthwith after demand.





11.2 Landlord's Rights of Cancellation:

        (a) The Tenant shall not assign this Lease or sublet the whole or any
        part of the Premises unless:

            (i)    it shall have received or procured a bona fide written offer
                   therefor to take an assignment or sublease which is not
                   inconsistent with, and the acceptance of which would not
                   breach, any provisions of this Lease if this section is
                   complied with and which the Tenant has determined to accept
                   subject to this section being complied with, and

            (ii)   it shall have requested and obtained the consent in writing
                   of the Landlord thereto.

Any request for such consent shall be in writing and accompanied by a true copy
of such offer, and the Tenant shall furnish to the Landlord all information
available to the Tenant or any additional information requested by the Landlord,
as to the responsibility, reputation, financial standing and business of the
proposed assignee or sublessee.

        (b) Within 15 days after the receipt by the Landlord of such request for
        consent and of all information which the Landlord shall have requested
        hereunder (and if no such information has been requested, within 15 days
        after receipt of such request for consent), the Landlord shall have the


                                      -23-


        right upon notice to the Tenant, if the request is to assign this Lease
        or sublet the whole of the Premises, to terminate this Lease or, if the

        Lease such part of the Premises as are requested to be sublet, in each
        case as of a date of the proposed assigning or subletting, as the case

        the case may be, of the Premises in accordance with such notice and Rent
        shall be apportioned and paid to the date of surrender and, if a part
        only of the Premises is surrendered, Rent shall thereafter be

        further assignment or subletting which shall remain subject to the
        provisions of this Article.


11.4 Dealings by Landlord:

covenants and obligations of the Landlord under this Lease, the Landlord shall,
without further written agreement, be freed and relieved of liability with
respect to such covenants and obligations.

same.

In the event of any conflict between the terms of this Lease and the terms of
such notice or short form, the terms of this Lease shall prevail.

        estimate same on a reasonable basis. Upon payment of such amount by the
        Tenant to the Landlord, the Tenant shall be entitled to occupancy of the
        Premises for the remainder of the Term in accordance with this Lease;
        and/or

        (g) suspend the supply to the Premises of any benefit, service, utility
        or Additional Service furnished by the Landlord until the default is
        cured.

alternative, and the express provisions hereunder as to certain rights and
remedies are not to be interpreted as excluding any other or additional rights

any default by the other at any time or times in respect of any obligation of
the other herein shall not operate as a waiver of the non-defaulting party=s

way the rights of the non-defaulting party in respect of any such continuing or
