Landlord the excess without interest or, if the sum of the instalments paid by
the Tenant during the preceding calendar year exceed the amounts calculated
under paragraphs 4.4(b), the Landlord will pay the excess to the Tenant.

Landlord does apply all or any portion of the Security Deposit as compensation
for breach of the Lease, then the Tenant will upon written demand remit to the
Landlord a sufficient amount to restore the Security Deposit to the original sum
deposited, plus any G.S.T. owing in connection therewith. The Landlord may, at
any time, return the Security Deposit to the Tenant rather than apply it to
rectify a breach of the Lease by the Tenant.

                           180 days after the occurrence of the damage or the
                           cost of repairing or rebuilding it would exceed by
                           more than $10,000 the proceeds of the Landlord's
                           insurance available for that purpose, or

                  (ii)     if the Premises are damaged by any cause and the
                           damage is such that the Premises or a substantial

                           business and in the reasonable opinion of the
                           Landlord cannot be repaired or rebuilt with
                           reasonable diligence by 6 months before the end of

Landlord with reasonable speed but in any event within 15 days after the giving
of the notice of termination, and all Rent will be apportioned and paid to the
date of damage. In the event of damage to the Premises or to the Building and if

by the Landlord to do so, submit plans and specifications therefor.

structure of the Building or to the exterior appearance of the Building.

repair properly as required under this Part and to the reasonable satisfaction
of the Landlord, the Landlord may make such repairs without liability to the
Tenant for any loss or damage that may accrue to the Tenant by reason thereof,
and upon completion thereof, the Tenant will pay the Landlord's actual
reasonable costs in the circumstances plus 15% of such costs, for making such
repairs, immediately upon presentation of an invoice for such costs.

install equipment that will exceed or overload the capacity of utility or
service facilities and if, in the reasonable opinion of the Landlord, equipment
installed by the Tenant requires additional facilities, they will be installed

additional equipment at the Tenant's expense, which will not exceed 15% of the
cost of the additional equipment.

companies acceptable to the Landlord.

         (b) The Tenant will not do or permit to be done, or omit to do or
permit another person to omit to be done, any act which may render void or

mortgage, charge or encumber the Lease, in whole or in part, nor sublease all or
any part of the Premises or permit them to be used or occupied by any other
person (collectively "Transfer"), without the prior written consent of the
Landlord, which consent may not be unreasonably withheld or delayed. Any

11.2 Terms and Conditions of Transfer. The following terms and conditions apply
in respect of any Transfer:

and will not be released from the performance of each and every one of the

Tenant, in any case without the consent of the Landlord, the Landlord may
collect Rent from the assignee, subtenant or occupant, and apply the net amount
collected to the Rent reserved in this Lease, but the assignment, sublease,
occupancy or collection will not be considered a waiver of this covenant, or the
acceptance of the assignee, subtenant or occupant as Tenant.

11.5 No Advertising. The Tenant will not advertise the whole or any part of the
Premises for lease nor permit any agent or broker to do so, unless the prior
written approval of the Landlord has been received.

person or persons holding Control on the date of execution of this Lease or if
other steps are taken to accomplish a change of Control, the Tenant will
promptly notify the Landlord in writing of the change, which will be considered
to be an assignment of this Lease to which this Part 11 applies; and whether or
not the Tenant notifies the Landlord, the Landlord may terminate this Lease
within 60 days after the Landlord becomes aware of the change unless the
Landlord previously had consented to the change. Any subsequent change of
Control will similarly be subject to the prior written consent of the Landlord.

                           foregoing provisions there continues to be a
                           continuity of management policies and practices of
                           the Tenant, in spite of any such change in Control.

provincial and federal statutes and regulations now in force or which may

little interference to the conduct of the Tenant's business as is reasonably
possible, to enable the Landlord to inspect the Premises and to comply with or
cause the Tenant to comply with any municipal by-law or provincial statute now
or in the future applicable to the Premises whether or not the application of
the by-law or statute to the Premises results from an act or omission of the
Landlord or any other person.

         (c) If the Tenant has knowledge, or has reasonable cause to believe
that any Hazardous Substance has come to be located on, under or about the
Premises, the Tenant will, upon discovery of the presence or suspected presence
of Hazardous Substance, give written notice of that condition to the Landlord.
Failure to provide written notice will be a default, permitting the Landlord to
terminate the Lease immediately.

         (d) If the Landlord, in its sole discretion, believes that the Premises
or the environment have become contaminated with any Hazardous Substance, the
Landlord, in addition to its other rights under this Lease, may enter upon the
Premises and obtain samples from the Premises and under the Premises, for the
purpose of analyzing the same to determine whether and to what extent the
Premises or the environment have become so contaminated. To the extent that

Tenant will reimburse the Landlord for the costs of such inspection, sampling
and analysis.

         (e) Without limiting the above, the Tenant will indemnify and save
harmless the Landlord and its directors, officers and agents from and against
any and all claims, losses, liabilities, damages, costs and expenses, including
without limitation, legal fees and costs on a solicitor and own client basis,
arising out of or in any way connected with the use, manufacture, transportation
storage, emission or disposal of Hazardous Substances by the Tenant, its agents
or contractors, or any others under the control of the Tenant, on, under or
about the Premises or elsewhere in the Building including, without limitation,
the cost of any required or necessary repair, remediation or detoxification and
the preparation of any closure or other required plans in connection with this
Lease. The indemnity obligations of the Tenant under this paragraph will survive

the Tenant will store approximately 22 pounds of propane on the Premises and
that the Tenant will manufacture hydrogen, oxygen and ozone on the Premises as
part of its business. The Landlord's acknowledgment that these substances "will
be located on the Premises in no way diminishes the Tenant's duty to comply with
the other provisions of this Part 12 or of this Lease.

                                    PART 13.

covering, interior or exterior lighting, or mechanical, or electrical system or

         (b) The Tenant will present to the Landlord plans and specifications
for any works the Tenant proposes to undertake at the time approval is sought
and the work will be done in a good and workmanlike manner with first class
materials.

         (c) The Tenant will not make or permit to be made any changes,

Landlord's reasonable costs and expenses in connection with any installations
and changes by the Tenant, including, without limitation, the costs of
supervising and inspecting the work and the cost of examining the Tenant's
drawings and specifications.

14.2 Removal of Installations and Restoration by Tenant.

         (a) All Leasehold improvements when installed become the property of
the Landlord at the end of the Term or earlier termination of this Lease,
without compensation to the Tenant, but the Landlord will have no responsibility
for the repair, replacement, operation, maintenance or insurance of the
Leasehold improvements, which will remain the responsibility of the Tenant.

         (b) At the end of the Term the Tenant will, at its expense, remove the
Leasehold improvements to the extent requested by the Landlord and all
furniture, furnishings, equipment and trade fixtures and make good any damage
caused to the Premises or the Building or the Land by such installation or
removal and restore the Premises to a condition of good and substantial repair,
as required in paragraph 7.2. Every installation, removal or restoration by the
Tenant of furniture, furnishings, equipment and, if applicable, Leasehold
improvements, will be done at the sole expense of the Tenant.

<PAGE>

         (c) If the Tenant does not remove any Leasehold improvements, or its
furnishings, furniture or equipment as required by the Landlord, the Landlord
may, without liability on its part, and not as a bailee, without notice to the
Tenant, enter the Premises and remove such items at the Tenant's expense, plus
ad administration charge of 15% of such amount, which will be paid by the Tenant
to the Landlord as Additional Rent, on demand, and such items may, without
notice to the Tenant or to any other person and without obligation to account
for them, be sold, destroyed, disposed of or used by the Landlord as it
determines.

         (d) The Tenant's obligations under this paragraph 14.2 will survive the
expiration or earlier termination of this Lease.

14.3 Not to Overload Floors. The Tenant will not bring on the Premises anything
that by reason of its weight, size or use, might damage the Premises and will

immediately repair any damage or pay to the Landlord the cost of repairing the
damage and will also pay for any consequential damages arising from the
overloading.

14.4 Tenant to Discharge All Liens. The Tenant will promptly pay all its
contractors, subcontractors and materialmen and do all things necessary to
ensure that no lien is claimed against the Premises or the Land or any other
part of the Building or the Land in connection with work, services or material
supplied or claimed to have been supplied by the Tenant and should such a claim
of lien be filed, the Tenant will cause it to be discharged or vacated at the
Tenant's expense within 21 days after it is brought to the attention of the
Tenant or provide adequate security for it to the extent approved by the
Landlord. The Landlord may, but it is not obligated to discharge the lien by
paying the amount claimed to be due into court, or by any other means available
to the Landlord, and the amount paid, plus all costs, including without
limitation, professional and solicitors fees (on a solicitor and own client
basis) incurred by or on behalf of the Landlord concerning the lien, plus any
damages suffered by the Landlord as a result of the filing of the lien will be
forthwith paid, on demand, by the Tenant as Additional Rent. The Tenant will
allow and keep posted on the Premises any notice which the Landlord may wish to
post under the provisions of the Builders' Lien Act or any legislation in
amendment or substitution thereof.

14.5 Signs, Awnings and Canopies.

         (a) The Tenant will not place or permit to be placed or maintained on
the roof or on any exterior or interior door, wall or window of the Building or
elsewhere in the Building or upon the Land any sign, awning, canopy, decoration,

authorities having jurisdiction regarding permits, licences and other consents
for any signs installed.

         (d) Following approval by the Landlord, any exterior sign erected by
the Tenant will be illuminated in the manner and at the times required by the
Landlord. All costs, including, without limitation, electrical costs pertaining
to the sign, whether separately metered or allocated by the Landlord, will be
paid, when due, as Additional Rent.

         (e) At the expiration or earlier termination of the Lease, the Tenant
will remove, at its expense, any sign installed by it, repairing any damage
caused thereby.

<PAGE>

         (f) The Tenant will indemnify and save the Landlord harmless from any
claims, loss or damage arising directly or indirectly from the Tenant's signage
provided that such claim, damage or loss is not caused by the wilful act,
negligence or omission of the Landlord or those persons for whom the Landlord is
responsible at law.

         (g) The Tenant waives all statutory rights now or in the future granted
under municipal by-law in respect of any sign or signs that the Landlord erects
in the Building and will execute immediately on the Landlord's request waivers,
certificates or other papers in order to give effect to this waiver.

                                    PART 15.
                                DEFAULT OF TENANT

15.1 Tenant's Default. If the Tenant fails to pay any Rent when due, whether or
not demanded by the Landlord and such default continues after 5 days notice from
the Landlord, or if the Tenant fails to observe or perform any of its other
obligations under this, Lease, and the Tenant has not within 10 business days
after notice from the Landlord specifying the default, cured the default or if
curing the default should reasonably require a longer period if the Tenant has
not commenced to cure and diligently pursues the curing of the default, or if
re-entry is permitted under other terms of this Lease or if the Landlord has
reasonable cause to believe the Tenant intends to cease operating or to vacate
the Premises, the Landlord in addition to any other right or remedy may:

         (a) re-enter and remove all persons and property from the Premises and
the property may be removed and stored in a public warehouse or elsewhere at the
cost of, and for the account of, the Tenant, all without service of notice or
resort to legal process and without the Landlord being guilty of trespass or
becoming liable for loss or damage occasioned by any of those actions; and

         (b) terminate this Lease and all of the Tenant's rights under it.

15.2 Bankruptcy or Insolvency of Tenant. If:

         (a) any of the goods and chattels of the Tenant on the Premises at any
time during the Term are seized or taken in execution or attachment by a
creditor of the Tenant or the Tenant receives a notice from one or more of its
secured creditors that the creditor(s) intend to realize on security located at
or upon the premises,

         (b) the Tenant makes an assignment for the benefit of (creditors or any
arrangement or compromise, or a bulk sale from the Premises other than a bulk
sale to an assignee or sublessee under an assignment or sublease which under
paragraph 11 was consented to,

         (c) a receiver-manager is appointed to control the conduct of the
business of the Tenant on or from the Premises and such appointment is not
vacated within 8 days,

Act now or hereafter in force for bankrupt or insolvent debtors or files any
proposal or a notice of intention to file a proposal,

         (e) proceedings are instituted by the Tenant or any other person for an
order for the winding-up of the Tenant, or other termination of the corporate
existence of the Tenant,

         (f) the Premises, without the written consent of the Landlord, become
and remain vacant for a period of 30 days except as necessitated for the
completion of repairs or are used by any persons other than those entitled to
use them under the terms of this Lease,

<PAGE>

         (g) the Tenant, without the written consent of the Landlord, abandons
or attempts to abandon the Premises or sells or disposes of its goods or
chattels or removes any of them from the Premises so that there would not, in
the event of abandonment, sale or disposal, be sufficient goods on the Premises
subject to distress to satisfy all Rent due or accruing due hereunder, or

         (h) the Lease or any of the Tenant's assets on the Premises are taken
under a writ of execution, charge, debenture or other security instrument, then
the Landlord may re-enter and take possession of the Premises as though the
Tenant or any other occupant of the Premises was holding over after the
expiration of the Term and this Lease may, at its option be immediately
terminated by notice left upon the Premises.

15.3 Notice from Secured Creditors. The Tenant will immediately notify the
Landlord if it receives from any of its secured creditors a notice under the
Bankruptcy and Insolvency Act, or any legislation in amendment or substitution
therefor, advising the Tenant that the secured creditor intends to realize upon
its security located on the Premises.

15.4 Proposals. Unless the Landlord expressly consents thereto, which the
Landlord is not obliged to do, the Tenant will not exercise any right to
repudiate the Lease under the terms of a proposal filed under the Bankruptcy and
Insolvency Act, or any legislation in amendment or substitution therefor.

15.5 Landlord may Perform Tenant's Obligations. If the Tenant fails to perform
an obligation of the Tenant under this Lease after the expiration of the notice
periods set out in paragraph 15(1), the Landlord may perform the obligation and
for that purpose may enter on the Premises without notice and do anything in
respect of the Premises that the Landlord considers necessary to cure the
default. The Tenant will pay as Additional Rent all costs and expenses incurred
by or on behalf of the Landlord plus 15% for overhead upon presentation of a
bill. The Landlord will not be liable to the Tenant for loss or damage resulting
from such action by the Landlord, including loss or damage resulting from the
negligence of the Landlord or another person for whose negligence the Landlord
is responsible in law.

15.6 Right to Relet.

         (a) If the Landlord re-enters, as provided in this Lease, it may,
without terminating the Tenant's rights under this Lease, make alterations and
repairs considered by the Landlord necessary to facilitate a reletting, and
relet the Premises or any part thereof as agent of the Tenant for such period of
time and at such rent and upon such other terms and conditions as the Landlord
in its discretion considers advisable.

         (b) Upon each reletting all rent and other monies received by the
Landlord from the reletting will be applied, first to the payment of
indebtedness other than Rent due hereunder from the Tenant to the Landlord,
secondly to the payment of costs and expenses of the reletting including
brokerage fees and legal fees and costs of the alterations and repairs, and
third to the payment of Rent due and unpaid under this Lease. The residue, if
any, will be held by the Landlord and applied in payment of future rent as it
becomes due and payable.

         (c) If the rent received from the reletting during a month is less than
the Rent to be paid during that month by the Tenant, the Tenant will pay the
deficiency to the Landlord. The deficiency will be calculated and paid monthly.

15.7 Reentry Without Termination. No re-entry by the Landlord will be construed
as an election on its part to terminate this Lease unless a written notice of
that intention is given to the Tenant. Despite a reletting without termination,
the Landlord may elect at any time to terminate this Lease for a previous
unremedied breach.

<PAGE>

15.8 Damages. If the Landlord terminates this Lease for any breach, then, in
addition to other remedies, it may recover from the Tenant all damages it incurs
by reason of the breach including, without limitation, the cost of recovering
the Premises, reasonable professional and other legal fees (on a solicitor and
own client basis), the unamortized portion of any allowance, concession or
inducement paid by the Landlord under the terms of the tenancy (on the basis of
an assumed rate of depreciation on a straight line basis to zero over the Term)
and the worth at the time of termination of the excess, if any, of (i) the
amount of rent and charges equivalent to Rent reserved in this Lease for the
remainder of the Term over (ii) the then reasonable rental value of the Premises
for the remainder of the Term, calculated on a present value basis, all of which
amounts will be immediately due and payable by the Tenant to the Landlord.

15.9 Acceleration of Rent. If any of the events referred to in paragraph 15.1 or
paragraph 15.2 occur then, in addition to all other rights available to the
Landlord, including the rights referred to in this paragraph 15.9, the full
amount of the current month's Basic Rent and Additional Rent, and all other
payments required to be made monthly by the Tenant, and the next ensuing 3
months' Basic Rent and Additional Rent will immediately become due and payable
as accelerated rent, and the Landlord may recover the accelerated rent in the
same manner as Rent in arrears, including immediately distraining for it
together with all other arrears then unpaid.

15.10 Expenses for Remedying Breach. If the Landlord brings any proceeding
against the Tenant arising from an alleged breach of an obligation of the Tenant
in this Lease and it is established that the Tenant is in breach of that
obligation, the Tenant will pay to file Landlord all reasonable costs and
expenses incurred by the Landlord in those proceedings including, without
limitation, legal fees, on a solicitor and own client basis.

15.11 Interest on Overdue Monies. All overdue monies payable to the Landlord by
the Tenant on any account whatever will bear interest at the prime rate of HSBC
Bank Canada per annum plus 5% from the due date until paid in full.

15.12 No Exemption from Distress. None of the property of the Tenant on the
Premises is exempt from levy by distress for Rent in arrears, and a claim being
made for exemption by the Tenant or on distress being made by the Landlord, this
paragraph 15.12 may be pleaded as an estoppel against the Tenant in any
proceedings brought to test the right to levy upon property claimed to be
exempt.

                                    PART 16.
                         REMEDIES OF LANDLORD AND WAIVER

16.1 Remedies Cumulative. No exercise of a specific right or remedy by the
Landlord or by the Tenant precludes it from, or prejudices it in, exercising
another right or pursuing another remedy or maintaining an action to which it
may otherwise be entitled either at law or in equity.

16.2 No Waiver. The waiver by the Landlord or the Tenant of a breach of an
obligation in this Lease will not be considered to be a waiver of a subsequent
breach of that obligation or another obligation. The subsequent acceptance of
Rent by the Landlord will not be a waiver of a preceding breach by the Tenant of
an obligation in this Lease, regardless of the Landlord's knowledge of the
preceding breach at the time of acceptance of the Rent. No obligation in this
Lease will be considered to have been waived by the Landlord or by the Tenant
unless the waiver is in writing signed by the Landlord or by the Tenant, as the
case may be.

16.3 Injunctive Relief. If the Tenant breaches or threatens to breach any of the
terms of this Lease, the Landlord will have the right to injunctive relief, as
if no other remedies were provided for in this Lease.

<PAGE>

16.4 Effect of Tenant Default on Renewals. If the Tenant is in default under
this Lease at the time fixed as the commencement of any renewal or extension of
this Lease, whether by renewal or extension option contained in this Lease or in
a separate agreement, the Landlord may cancel such option or agreement for
renewal or extension of the Lease, upon written notice to the Tenant.

                                    PART 17.
                               ACCESS BY LANDLORD

17.1 Right of Entry.

         (a) The Landlord and its agents may enter the Premises on reasonable
notice at all reasonable times to examine them and to show them to a prospective
purchaser, tenant or mortgagee.

         (b) During the 6 months prior to the expiration of the Term the
Landlord may place upon the Premises a notice "For rent" which the Tenant will
permit to remain without interference.

         (c) If after notice to the Tenant as provided for in this Lease or if
no notice is provided for, upon reasonable notice in the circumstances, the
Tenant is not present to open and permit entry into the Premises when the
Landlord reasonably requires entry, the Landlord or its agents may enter by a
master key or may forcibly enter without rendering the Landlord or its agents
liable for any damage or trespass and without affecting the Lease. Provided that
the Landlord acts in a reasonable manner, nothing in this paragraph 17.1 imposes
on the Landlord an obligation, responsibility or liability for the care,
maintenance or repair of the Premises or any part thereof except as specifically
provided in this Lease. The Landlord will have the right upon reasonable notice
to enter on the Premises in order to install, construct, operate, maintain,
repair and replace any utilities and services, but the Landlord in doing so will
exercise such right in a manner which is commercially reasonable to minimize the
extent of interference with the use and enjoyment of the Premises.

17.2 Roof and Walls. The Landlord will have the exclusive right to use all or
any part of the roof of the Building for any purpose; to erect additional
stories or other structures over all of any part of the Building; to erect in
connection with the construction thereof temporary scaffolds and other aids to
construction on the exterior of the Building, provided that access to the
Premises will not be unreasonably denied and that there is no unreasonable
interference with the Tenant's business and occupation of the Premises.

17.3 Excavation. If an excavation is made upon the Land or any lands adjacent to
the Premises, or is authorized to be made, the Tenant will give to the person
making the excavation permission to enter the Premises for the purpose of doing
work required by the Landlord, without claim for damages or indemnification
against the Landlord or abatement or diminution of Rent.

                                    PART 18.
                      LANDLORD'S COVENANTS AND OBLIGATIONS

18.1 Taxes. Subject to Part 4, the Landlord will pay all real property taxes
(including local improvement rates) that may be assessed by a lawful authority
against the Building and the Land or either of them.

18.2 Quiet Enjoyment. Subject to the observance and performance by the Tenant of
all of its obligations under this Lease, the Tenant may use and possess the
Premises, in accordance with the provisions of this Lease, for the Term, without
interference by the Landlord, or any other party claiming by, through or under
the Landlord, except as otherwise provided in this Lease.

                                   OVERHOLDING

19.1 No Tacit Renewal. If the Tenant remains in possession of the Premises after
the end of the Term and without the execution and delivery of a new lease or
written renewal or extension of this Lease, there is no tacit or other renewal
of this Lease, and the Tenant will be considered to be occupying the Premises as
a Tenant from month to month at a monthly rental payable in advance on the first
day of each month equal to the total Rent payable for the previous month plus 50
per cent.

                                    PART 20.
                                 OPTION TO RENEW

20.1 Option to Renew. Provided that:

         (a) Tenant pays the Rent and all other monies payable by it under this
Lease and performs and has consistently performed all of its obligations under
this Lease punctually and in accordance with this Lease and is otherwise not in
default of any of its obligations to the Landlord; and

         (b) the original Tenant has not assigned this Lease or sublet or
permitted a change in occupancy or other Transfer of the Premises; and

         (c) there has been no change in Control of the Tenant; then the Tenant
will have the option of renewing this Lease by notice in writing given to the
Landlord not later than 6 months nor earlier than 8 months prior to the expiry
of the Term for an additional term of 3 years on the same terms and conditions
set out in this Lease, except that:,

         (d) the Basic Rent to be paid during each renewal term will be the fair
market rent at the time of the exercise of the option for space of comparable
size, quality and location to that of the Premises, as determined by agreement
between the Landlord and the Tenant, with or without the assistance of
mediation, or if they fail to agree within months prior to the expiration of the
existing Term, then the Basic Rent will be determined by a single arbitrator
appointed under the Commercial Arbitration Act, as such legislation may be
amended or substituted from time to time, whose decision will be final and
binding upon the Landlord and the Tenant. The cost of the arbitration will be
borne by the Landlord and the Tenant equally. In any event the Basic Rent for
any renewal term will not be less than the Basic Rent applicable during the most
recent Lease Year nor will it be less than the Basic Rent paid during the last
12 month period of the preceding term, and

         (e) concerning any renewal term, the Landlord will have no obligation
to pay or provide to the Tenant any allowance, concession or inducement of any
nature, or provide any free rent or discounted rent of any nature, or provide
any fixturing period, or do or perform any work in the Premises.

20.2 Renewal Documentation.

         (a) The Landlord may, at its option, and at the Tenant's expense,
require that the Tenant enter into an agreement prepared by the Landlord to give
effect to the renewal term or execute a new lease for the renewal term on the
Landlord's standard net lease form for the Building currently in use at such
time.

         (b) During the period, if any, between the expiration of the Term, or
most recent renewal term, and the date upon which the new renewal rent is
determined by an arbitrator, or otherwise, the Tenant will pay Rent at the rates
and in the manner provided for in the Lease for the period immediately preceding
the expiry of the Term or most recent renewal term and, following determination
of the renewal rent, the Tenant will pay to the Landlord interest, at the rate
prescribed in paragraph 15.11 on the excess amount of the renewal rent.
