LESSEE:   North American Equipment Ltd. ("LESSEE")
ADDRESS   #2,53016 Highway 60
          Spruce Grove, Alberta
          T7X 3G7
          1-780-960-7171

This Master Lease Agreement ("Agreement"), including the terms and conditions on
the reverse side hereof and any Schedules hereto, correctly sets forth the
entire agreement between Wajax Finance Ltd. ("Lessor") and Lessee. No agreements
or understandings shall be binding on either of the parties hereto unless in
writing and executed by the parties hereto.

1.   Lease. Lessor hereby leases to Lessee and Lessee hereby leases from Lessor
     the personal or movable property (the "Equipment") described in the Lease
     Schedule(s) (the "Schedule") executed and to be executed by the parties and
     attached hereto to form part hereof. Each Schedule shall constitute a
     separate lease of Equipment and the provisions hereof will be deemed to be
     a part thereof. In contemplation of entering into a Schedule with respect
     to certain Equipment, Lessor and Lessee may enter into an Interim Lease
     Funding Agreement providing for the acquisition of such Equipment by Lessor
     and at the request of Lessee.

2.   Term and Rental. The term of the lease for any Equipment ("Lease Term"),
     its commencement date ("Lease Commencement Date") and the amount of the
     rental ("Rental"), together with the sales tax and goods and services tax
     thereon, if applicable, and the terms of payment thereof, will be as
     provided in the Schedule related to such Equipment. Lessee's obligation to
     pay Rental and other amounts owing under a Schedule or hereunder shall be
     absolute and unconditional without any claim of setoff or compensation by
     Lessee. Lessee shall not be permitted to prepay its Rentals or other
     obligations. Lessee shall on the Lease Commencement Date pay Lessor the
     number of advance rentals, if any, set forth in the Schedule. Such advance
     rentals shall not constitute a security deposit and shall not be refundable
     to Lessee under any circumstances, but shall be applied by Lessor against
     subsequent Rental in reverse order of maturity.

3.   Use. Lessee will cause the Equipment to be operated in accordance with any
     applicable manufacturer's manuals or instructions, by competent duly
     qualified personnel, in accordance with applicable govemmental regulations,
     if any, and for business purposes only. Lessee agrees not to remove the
     Equipment from its location as set forth in the related Schedule without
     Lessor's prior written consent, provided that Equipment which is mobile by
     nature shall be based at such location but may be operated away from such
     location in the ordinary course of Lessee's business.

     Maintenance. Lessee assumes all risk of loss or damage to the Equipment
     from the date of shipment thereof until it is returned to Lessor and the
     Schedule with respect to it is terminated, and agrees that the Equipment
     will be installed and maintained in good operating condition at Lessee's
     expense and returned to Lessor promptly at the expiry of the Lease Term in
     good operating condition (ordinary wear and tear excepted).

5.   Alterations. Lessee may make alterations, additions or improvements to the
     Equipment provided such alterations, additions or improvements shall not
     decrease the value of the Equipment or impair its utility. Any alterations,
     additions or improvements to the Equipment shall be at Lessee's expense and
     shall belong to and become the property of Lessor subject to the terms of
     this Agreement during the Lease Term of such Equipment. Lessee may remove
     any such alterations, additions or improvements at the expiration of the
     Lease Term of such Equipment, provided Lessee shall repair any damage to
     the Equipment or the premises where located resulting from or occasioned by
     such removal and provided any such removal shall restore the Equipment to
     its original state and condition (ordinary wear and tear excepted).

6.   Insurance. As and from the earlier of the data upon which Lessor pays any
     part of the cost of an item of Equipment or acquires ownership of or title
     to an item of Equipment or bears any risk, responsibility and liability
     therefor and thereafter throughout the Lesse Term of an item of Equipment.
     Lessee shall at its sole expense:
     (a)  insure the Equipment against all risks of physical loss or damage,
          including without limitation loss by fire (including extended
          coverage), theft, collision and such other risks of loss as are
          customarily covered by insurance on such type of equipment by prudent
          operators of businesses similar to that in which Lessee is engaged, in
          such amounts, in such form and with such insurers as shall be
          satisfactory to Lessor, but in no event shall such insurance be less
          than an amount (the "Loss Value") equal to the present value from time
          to time of all unpaid amounts due as Rental or otherwise (including
          the purchase option amount or any amounts due if the purchase option
          is not exercised, if applicable) with respect to such Equipment,
          calculated by discounting such amounts at the rate of six percent (6%)
          per annum, which amount the parties agree represents an estimate of
          the full replacement value of the Equipment from time to time during
          the Lease Term.

IN WITNESS WHEREOF This Agreement made as of the 15 day of September, 2000.

     (b)  maintain public liability and property damage insurance in respect of
          the use, operation and possession of the Equipment and the ownership
          thereof by Lessor with insurers satisfactory to Lessor in such form
          and with such limits of liability as Lessor may from time to time
          reasonably require.
     Each insurance policy will name Lessee and Lessor as insureds, will name
     Lessor as an additional insured and loss payee thereof and shall contain a
     clause requiring the insurer to give to Lessor at least thirty (30) days'
     prior written notice of any alteration in the terms of such policy or of
     the cancellation thereof. At Lessor's request, Lessee shall furnish to
     Lessor a certificate or certificates of insurance or other evidence
     satisfactory to Lessor that such coverage is in effect, provided, however,
     that Lessor shall be under no duty to either ascertain the existence of or
     to examine such insurance policy or to advise Lessee in the event such
     insurance coverage shall not comply with the requirements hereof. If any
     such policies of insurance contain a co-insurance clause, Lessee shall
     either cause such coinsurance clause to be waived or maintain at all times
     a sufficient amount of insurance to meet the requirements of any such
     co-insurance clause so as to prevent Lessee from becoming a co-insurer
     under the terms of any such policy. Lessee will, at its expense, make all
     proofs of loss and take all other steps necessary to recover insurance
     benefits unless advise in writing by Lessor that Lessor desires so to do at
     Lessee's expense. Proceeds of insurance shall at the option of Lessor be
     disbursed by Lessor against satisfactory invoices for repair or replacement
     of Equipment, or be retained by the Lessor for application against Lessee's
     obligations hereunder, and if the proceeds received are less than the Loss
     Value of the Equipment lost, Lessee shall immediately pay to Lessor the
     amount of such deficiency. The total or partial loss of the Equipment or
     its use or possession shall not relieve Lessee from its obligations and
     liabilities hereunder.

7.   Uninsured Loss and Damage. If any item of Equipment is lost, stolen,
     destroyed or damaged beyond repair and is not covered by insurance in the
     amount required by Section 6 for any reason, or in the event of any
     condemnation, confiscation, seizure or expropriation of such item, Lessee
     shall immediately pay to Lessor the Loss Value of such item, at which time
     Lessor will transfer to Lessee, without recourse or warranty of any nature
     whatsoever, all of Lessor's right, title and interest in such item of
     Equipment.

8.   Laws and Regulations. Lesses shall comply with all laws relating to the
     Equipment, its possession and use and the ownership thereof by Lessor.

9.   Representations and Warranties of Lessee. Lessee represents and warrants to
     Lessor, which representations and warranties shall be deemed to be repeated
     on each day that this Agreement remains in force, that:
     (a)  Lessee, if a corporation, is duly incorporated and validly existing in
          good standing under the laws of the jurisdiction of its incorporation,
          and Lessee has the power, corporate or otherwise, to enter into this
          Agreement and all certificates and other documents required hereby or
          referred to herein;
     (b)  this Agreement has been duly authorized by all necessary action,
          corporate or otherwise, on the part of Lessee, has been duly executed
          and delivered by Lessee and constitutes the legal, valid and binding
          agreement of Lessee enforceable against it in accordance with their
          terms;
     (c)  the execution, delivery, observance and performance of this Agreement
          does not and will not result in the breach of, constitute a default
          under, contravene any provision of, or result in the creation of any
          lien on or in any property or assets of the Lessee, pursuant to
          Lessee's constating, documents (if any) or any agreement, indenture or
          other instrument to which Lessee is a party or by which Lessee or any
          of its property or assets may be bound; and
     (d)  there are no actions, suits or proceedings pending or, to the
          knowledge of Lessee, threatened in any court or tribunal or before any
          competent authority against Lessee or any of its property or assets
          which, in the reasonable and bona fide opinion of Lessee, may have a
          material adverse effect on the financial condition or business of
          Lessee.
                                                                (Continued Over)

10.  Exclusion of Equipment Warranties. Lessee acknowledges that Lessee alone
     will have selected the Equipment, that Lessor does not deal in the
     Equipment and that Lessor does not and will not make any representation or
     warranty whatsoever, express or implied, with respect to the Equipment or
     its adequacy for Lessee's purpose or otherwise. Lessor will have no
     liability whatsoever (including, without limitation, liability for any
     indirect or consequential damages) arising from any latent or other defect
     in the Equipment including any fundamental breach, or other failure of
     performance, capacity or operation of the Equipment. If any Equipment is
     unsatisfactory for any reason, Lessee shall pay the Rental owing in respect
     of such Equipment without abatement and shall seek recourse solely against
     the supplier or manufacturer of such Equipment. For such purpose, Lessor
     assigns to Lessee the benefit of all warranties and guarantees provided by
     manufacturers or suppliers of Equipment. If the manufacturer or supplier
     substitutes replacement equipment for any Equipment described in a
     Schedule, Lessee will promptly give Lessor notice thereof together with
     such particulars as are necessary to prepare a corrected Schedule and such
     replacement equipment shall be deemed Equipment.

11.  Default Time is of the essence and it shall be a default hereunder
     ("Default") and under all Schedules if:
     (a)  Lessee fails to pay any Rental or other amounts payable under any
          Schedule or hereunder when due in the manner specified;
     (b)  Lessee fails to observe or perform any covenant or other obligation or
          provision of a Schedule or hereunder;
     (c)  Lessee becomes insolvent (within the meaning of the Bankruptcy and
          Insolvency Act) or commits or threatens to commit an act of bankruptcy
          or if a petition in bankruptcy, proposal, arrangement or
          reorganization under the Bankruptcy and Insolvency Act. Winding Up Act
          or Companies' Creditors Arrangement Act is filed by or against Lessee
          or if a receiver of receiver-manager is appointed for Lessee or a
          substantial part of Lessee's property;
     (d)  an encumbrancer or any other party takes possession of a substantial
          part of Lessee's property or any of the Equipment;
     (e)  any representation or warranty made by Lessee to Lessor in connection
          with the entering into of this Agreement or any statement in any
          document or agreement in connection herewith proves to have been
          untrue or incorrect when made or furnished;
     (f)  Lessee ceases or threatens to cease to carry on the business currently
          being carried on by it or disposes of all or substantially all of its
          property;
     (g)  any item of Equipment is confiscated, forfeited or seized or otherwise
          attached by anyone pursuant to any legal process or other means;
     (h)  if Lessee is a corporation, there is any change in its effective
          control without the prior written consent of Lessor;
     (i)  Lessee is in default under any other lease, contract, agreement or
          obligation now existing or hereinafter entered into with the Lessor
          or any assignee of Lessor whether Lessee is bound alone or with
          others;
     (j)  Lessee dies or becomes mentally incompetent, if an individual, or is
          dissolved, or amalgamated or wound up if Lessee is a corporation; and
     (k)  Lessor believes in good faith that the payment of the Rent or the
          performance or observation of any covenant herein is impaired or that
          the Equipment is in danger of being lost, damaged or confiscated, or
          of being encumbered by Lessee or seized or otherwise attached by
          anyone pursuant to any legal process or otherwise.

For greater certainty, Lessee acknowledges that a Default under one Schedule
shall be deemed Default under all Schedules.

12.  Remedies.
     (a)  Upon Default and any time thereafter Lessor may in addition to any
          other right or remedy Lessor may have at law or in equity Lessor shall
          have the rights and remedies set out below, all of which shall be
          enforced successively, concurrently and/or cumulatively:
          (i)   without further notice, take possession of the Equipment under
                any or all Schedules ("Repossession") and for such purpose
                Lessee hereby grants Lessor the right to enter its premises at
                the then current Equipment location for the purpose of
                Repossession and waives claims for any damages, whether to
                property or otherwise, arising out of a Repossession and
                acknowledges that Lessor may retain all prior payments as
                partial compensation for the use of the Equipment, and sell or
                lease the Equipment upon such terms as Lessor determines with or
                without notice, at private or public sale, with or without
                having the Equipment at the sale("Disposition");
          (ii)  upon five (5) days' prior written notice after the occurrence
                and continuance of Default, terminate this Agreement and any
                Schedule; or
          (iii) demand, as a genuine pre-estimate of liquidated damages for loss
                of bargain and not as a penalty, the Loss Value of the
                Equipment.
     (b)  Lessee will pay all costs arising or incurred by Lessor as a result of
          Default, including reasonable legal fees on a solicitor and his own
          client basis. Such costs with be first deducted from the proceeds of
          any Disposition, if an amount in excess of the Loss Value is received
          by Lessor, after costs, from the exercise of its remedies under
          Paragraph 12(a), Lessor shall pay to Lessee or any other party
          entitled by law to such payment, any such excess, and Lessee shall be
          liable for any deficiency.
     (c)  Lessee will pay Lessor interest at the Prime Rate plus 5% per annum
          calculated daily on all sums not received by Lessor when due and owing
          under the provisions of any Schedule or hereunder. Such interest shall
          be calculated monthly, not in advance, and be due and payable on the
          same days as provided for the payment of Rental so long as payment of
          any monies due and payable hereunder is in arrears. For purposes of
          this paragraph, "Prime Rate" means the rate of interest per annum
          which Royal Bank of Canada establishes from time to time at its
          principal office in Toronto for demand loans in Canadian dollars made
          to its customers in Canada and referred to as its prime rate of
          interest.
     (d)  Lessee waives all claims for damages against Lessor arising out of the
          Repossession, voluntary surrender, removal or Disposition of the
          Equipment;
     (e)  All rights of Lessor are cumulative and not alternative and may be
          exercised by Lessor separately or together, in any order or
          combination; and
     (f)  Lessor may discharge any claim, lien, mortgage, charge, security
          interest, encumbrance or any rights of others that may exist or be
          threatened against the Equipment, and in each such case the amounts so
          paid together with costs, charges and expenses incurred in connection
          therewith shall be added to the amount otherwise owed by Lessee.

13.  Ownership. Title to the Equipment is and shall remain in Lessor. During the
     Lease Term, the Equipment shall be and remain movable, personal and chattel
     property. Lessor shall not interfere with Lessee's right to possession and
     quiet enjoyment of the Equipment during the Lease Term provided Lessee
     performs its obligations hereunder and under any Schedule.
     Lessor may requite plates, labels, or other markings to be affixed to or
     placed prominently upon the Equipment indicating Lessor as the owner.

14.  Return on Termination. At the end of the Lease Term of each Schedule. the
     Equipment shall be returned to Lessor at a place reasonably designated by
     Lessor, unless a purchase option is exercised in respect thereof.

15.  Indemnification. Lessee shall be responsible for, and shall indemnify and
     save Lessor harmless from and against, all losses, claims, costs, expenses,
     damages, actions and liabilities, including without limitation solicitor's
     fees on a solicitor and his own client basis, in connection with, or
     arising from, this Agreement and/or any Schedule, the Equipment and the
     acquisition, possession, return ownership, leasing, use and-operation of
     the Equipment. This indemnity shall survive termination of this Agreement.

16.  Taxes, Liens, Change of Name. Lessee shall;
     (a)  punctually pay all sales and other taxes, licence fees, levies and
          assessments which may become payable at any time upon, or in respect
          of, the Equipment this Agreement and/or any Schedule;
     (b)  keep the Equipment free and clear of liens, charges, security
          interests, hypothecs, attachments, seizures and encumbrances of any
          kind, except those in favour of Lessor, and
     (c)  notify Lessor in writing no less than sixty (6O) days prior to
          changing its name or the location of its chief executive office.

17.  Remedying Defaults. If Lessee shall fail to perform or comply with any of
     Lessee's obligations hereunder and/or under a Schedule, Lessor in its
     discretion may do all such reasonable acts and make all such reasonable
     disbursements as may be necessary to remedy such failure and any
     disbursements so made shall be payable by Lessee on demand, together with
     interest at the rate stipulated in Paragraph 12(c) from the date of
     disbursement by Lessor to the date of payment by Lessee.

18.  Notices. Notices with respect hereto will be given in writing personally
     delivered to an officer or duly authorized representative of the recipient
     party or by prepaid registered mail addressed to such party at its address
     set forth above or such other address as it may in writing direct. Notice,
     if mailed as aforesaid, shall be deemed effective upon the fifth (5th)
     business day after the mailing thereof.

succeeding month throughout the Term.

4.3       Pro Rata Adjustment of Rent
          ---------------------------

          All rent shall be deemed to accrue from day to day, and if for any
reason it shall become necessary to calculate rent for irregular periods of less
than one (1) year or one (1) month, as the case may be, an appropriate pro rata
adjustment shall be made in order to calculate rent for such irregular period.

4.4       Payments Generally
          ------------------

          All payments by the Tenant to the Landlord of whatsoever nature
required or contemplated by this Lease shall be:

     (a)  paid to the Landlord by the Tenant in lawful currency of Canada;

     (b)  made when due hereunder, without prior demand therefor and without any
          set-off, compensation or deduction whatsoever at such place as the
          Landlord may designate from time to time to the Tenant;

     (c)  applied towards amounts then outstanding hereunder, in such manner as
          the Landlord may, in its discretion, see fit, and without restricting
          the generality of the foregoing, no acceptance by the Landlord of any
          amount less than the full sum which is due and owing by the Tenant
          shall constitute an accord and satisfaction or oblige the Landlord to
          accept in full settlement, anything less than the full amount owing
          and outstanding at any time;

     (d)  deemed to be rent, in partial consideration for which this Lease has
          been entered into, and shall be payable and recoverable as rent, such
          that the Landlord shall have all rights and remedies against the
          Tenant for default in making any such payment which may not be
          expressly said to be rent as the Landlord has for default in payment
          of rent;

     (e)  subject to an overdue charge if any such payment is not made when due,
          which charge shall be Additional Rent equal to the then existing Bank
          of Canada Prime Rate plus five (5%) per cent per annum on the overdue
          amount both before and after judgment payable with the next monthly
          instalment of Minimum Rent, all without prejudice to any other right
          or remedy of the Landlord; and

     (f)  made, if the Landlord so requests, by way of a series of cheques,
          postdated to the respective due dates of such payments, which the
          Tenant shall supply to the Landlord at the commencement of each Lease
          Year or earlier should the Landlord so request, or by way of an
          automatic debiting system by which payments are deducted from the
          Tenant's bank account and credited to the Landlord's, all at the
          Tenant's cost and all without prejudice to any other right or remedy
          of the Landlord.

4.5       Security Deposit
          ----------------

          The Tenant shall pay the Security Deposit to the Landlord which shall
be retained by the Landlord without liability for interest thereon, as security
for the due performance by the Tenant of its obligations under this Lease. The
Security Deposit may be applied, in the Landlord's discretion, to remedy any
default by the Tenant hereunder, whether in respect to the payment of monies or
otherwise, and in the absence of such default the Landlord shall return the
Security Deposit to the Tenant at the expiration of the Term. If any or all of
the Security Deposit is applied by the Landlord to remedy any default, then the
Tenant shall forthwith upon written demand from the Landlord, remit to the
Landlord such monies as are sufficient to restore the amount of money held on
deposit by the Landlord to the original balance.

5.1       Intent of Lease
          ---------------

          It is the intent of the parties and agreed that this Lease shall be
absolutely net and carefree to the Landlord such that, without limiting the
generality of the foregoing, the Tenant shall pay for its own account, and
without any variation, set-off or deduction, all amounts, charges, costs,
duties, expenses, fees, rates, sums, taxes and increases therein in any way
relating to the Premises.

5.2       Additional Rent
          ---------------

          Without limiting the generality of the preceding Section, the Tenant
shall pay to the Landlord as Additional Rent in each Lease Year the aggregate
of:

     (a)  Property Taxes;

     (b)  Landlord's Insurance as provided for in this Lease;

     (c)  the Sales Tax;

     (d)  such other amounts, charges, costs, sums or increases therein as are

5.3       Estimate of Additional Rent
          ---------------------------

          The Landlord may, in respect of any or all of the items of Additional
Rent, compute bona fide estimates of the amounts which are anticipated to accrue
in the next following Lease Year, calendar year or fiscal year, or portion
thereof, as the Landlord in its discretion may determine is the most appropriate
period for each or all items of Additional Rent, and the Landlord may provide
the Tenant with written notice of the amount of any such estimate.

5.4       Payment of Additional Rent
          --------------------------

          With respect to any item of Additional Rent which the Landlord elects
to estimate from time to time, following receipt of the written notice of the
estimated amount thereof, the Tenant shall pay to the Landlord such amount, in
equal consecutive monthly instalments throughout the applicable period with the
monthly instalments of Minimum Rent. With respect to any item of Additional Rent
which the Landlord has not elected to estimate from time to time, the Tenant
shall pay to the Landlord the amount of such item of Additional Rent, determined
pursuant to the applicable provisions of this Lease, forthwith upon receipt of
an invoice therefor.

5.5       Adjustment of Additional Rent
          -----------------------------

          Within ninety (90) days of the end of each Lease Year, calendar year
or fiscal year, or portion thereof, as the case may be, for which the Landlord
has estimated any item of Additional Rent, the Landlord shall compute the actual
amount of such item of Additional Rent, and make available to the Tenant for
examination a statement of the gross amount of such item of Additional Rent, and
the calculation of the Tenant's share thereof for each year or portion thereof.
If the actual amount of such item of Additional Rent, as set out in any such
statement, exceeds the aggregate amount of the instalments paid by the Tenant in
respect of such item, the Tenant shall pay to the Landlord the amount of the
excess within fifteen (15) days of the receipt of such statement. If the
contrary is the case, any such statement shall be accompanied by a refund to the
Tenant of any such overpayment without interest, provided that the Landlord may
first deduct from such refund any rent or other sum which is then owing by the
Tenant or in arrears.

adjusted in accordance with the adjustment provisions of this Lease.

                Landlord and shall contain a "cross liability" or "severability
                of interests" clause so that the Landlord and the Tenant may be
                insured in the same manner and to the same extent as if
                individual policies had been issued to each, and shall be for

          (ii)  "all risks" insurance upon its merchandise, stock-in-trade,
                furniture, fixtures and improvements including leasehold

                against breakage and damage from any cause, all in an amount
                equal to the full replacement value thereof, which amount in the

                Landlord; and

          (iii) boiler and machinery insurance on such boilers and pressure
                vessels as may be installed by or under the exclusive control of

          following additional provisions:

          (i)   provisions that the Landlord is protected notwithstanding any
                act, neglect or misrepresentation of the Tenant which might
                otherwise result in the avoidance of a claim under such policies
                and such that such policies shall not be affected or invalidated
                by any act, omission or negligence of any third party which is
                not within the knowledge or control of the insured(s);

          (ii)  provisions that such policies and the coverage evidenced thereby
                shall be primary and non-contributing with respect to any
                policies carried by the Landlord and that any coverage carried
                by the Landlord shall be excess coverage;

          (iii) all property and boiler insurance referred to above shall
                provide for waiver of the insurer's rights of subrogation as
                against the Landlord;

          (iv)  provisions that such policies of insurance shall not be
                cancelled without the insurer providing the Landlord thirty (30)
                days written notice stating when such cancellation shall be
                effective.

     (c)  Evidence satisfactory to the Landlord of all such policies of
          insurance shall be provided to the Landlord upon request.

     (d)  The Tenant shall further during the whole of the Term maintain such

          reasonably determine from time to time.

     (e)  The proceeds of all property insurance maintained by the Tenant are
          hereby assigned and made payable to the Landlord, and to the extent
          that such proceeds have been paid to the Landlord, they shall be
          released to the Tenant (provided the Tenant is not in default
          hereunder):

          (i)   upon the Tenant's written request, in progress payments, at
                stages determined by the Architect, upon receipt by the Landlord
                of a certificate from the Architect stating that repairs to each
                stage have been completed, free of liens, by the Tenant,
                provided that in the event of the Tenant's default in making
                such repairs and if the Landlord performs

<PAGE>

                                        7

                repairs, the proceeds may be applied by the Landlord to the
                costs thereof; or

          (ii)  upon termination of this Lease by the Landlord upon the
                happening of Substantial Damage or Destruction, but only to the
                extent of the value of any trade fixtures or stock-in-trade of
                the Tenant, but not to the extent of the value of any leasehold
                improvements made by the Tenant to the Premises.

8.2       Landlord's Insurance
          --------------------

               except foundations, and should the Landlord so elect, insurance
               to cover any loss of rental income which may be sustained by the
               Landlord;

          (b)  comprehensive general liability insurance against claims for
               bodily injury, including death and property damage in such form
               and subject to such deductions and exceptions as the Landlord may
               determine;

provided that nothing herein shall prevent the Landlord from providing or
maintaining such lesser, additional or broader coverage as the Landlord may
elect in its discretion.

8.3       Increases in Rates
          ------------------

          The Tenant shall not do, omit or permit to be done or omitted upon the
Premises anything which shall cause any rate of insurance upon the Premises or
any part thereof to be increased or cause insurance to be cancelled. If any such
rate of insurance shall be increased as aforesaid, the Tenant shall pay to the
Landlord the amount of the increase as Additional Rent. If any insurance policy
upon the Premises or any part thereof is cancelled or threatened to be cancelled
by reason of the use or occupancy by the Tenant or any act or omission as
aforesaid, the Tenant shall forthwith remedy or rectify such use, occupation,
act or omission upon being requested to do so by the Landlord, and if the Tenant
fails to so remedy or rectify, the Landlord may at its option terminate this
Lease forthwith and the Tenant shall immediately deliver up possession of the
Premises to the Landlord.

8.4       Recovery of Landlord's Premiums

          written  notice from the Landlord  requiring  that the Tenant  remedy,
          correct  or comply  or, in the case of any such  default  which  would
          reasonably  require  more than seven (7) days to  rectify,  unless the
          Tenant  shall  commence  rectification  within  the said seven (7) day
          notice period and thereafter  promptly and diligently and continuously
          proceed with the rectification of any such default;

behest of the Landlord shall be at the expense of the Tenant and the Tenant

remove and sell, by judicial or formal process or by private sale, any goods,
chattels and equipment at any place to which the Tenant or any other person may
have removed them, in the same manner as if they had remained and been

otherwise, the Tenant shall vacate and deliver up possession of the Premises in
the same state and condition as they where in upon delivery of possession to the
Tenant, subject to the exceptions from the Tenant's obligation to repair and

          If the Tenant shall be in default under this Lease beyond any period
given herein to rectify such default, or if the Landlord shall re-enter the
Premises or terminate this Lease when entitled to do so pursuant to default of
the Tenant hereunder, then:

     (a)  notwithstanding any such re-entry, termination, or the Term thereby

                                       18

     (b)  the Landlord may use such force as it may deem necessary for the
          purpose of gaining admittance to and retaking possession of the
          Premises and the Tenant hereby releases the Landlord from all actions,

                brokerage, legal fees and disbursements on an indemnification
                basis as between a solicitor and his own client, and the
                expenses of keeping the Premises in good order, repairing the
                same and preparing them for reletting; and

                     of the Landlord expected to be derived from the Lease
                     during the period which would have constituted the
                     unexpired portion of the Term had it not been terminated,
                     the greater of:

                     (I)  an amount determined by reducing to present worth at
                          an assumed interest rate of ten (10%) per cent per
                          annum all Minimum Rent and Additional Rent to become
                          payable during the period which would have constituted

                          to be made by the Landlord, who may make reasonable
                          estimates of when any such other amounts would have
                          become payable and may make such other assumptions of
                          fact as may be reasonable in the circumstances; and

                     (II) an amount equal to accelerated Minimum Rent and

                     loss of the benefit of the Lease over its unexpired Term,
                     without any requirement in law or in equity imposed upon
                     the Landlord to notify the Tenant prior to, concurrently
                     with, or at any time following the exercise of the option

          of the monthly Minimum Rent prevailing immediately prior to expiration
          or termination;

     (b)  Additional Rent as herein provided.

and subject always to all of the other provisions in this Lease insofar as the
same are applicable to a month to month tenancy and a tenancy from year to year
shall not be created by implication of law; provided that if the Tenant
continues to occupy the Premises without the written consent of the Landlord at
the expiration or other termination of the Term, then the Tenant shall be a
tenant at will and shall pay to the Landlord, as liquidated damages and not as
rent, an amount equal to the aggregate set forth above during the period of such
occupancy, accruing from day to day and adjusted pro rata accordingly and
subject always to all of the other provisions of this Lease insofar as they are
applicable to a tenancy at sufferance and a tenancy from month to month or from
year to year shall not be created by implication of law; provided that nothing

prior notice to the Tenant and recover such payment from the Tenant as
Additional Rent.

Landlord a Security Interest in all present and after-acquired goods,
stock-in-trade, inventory, fixtures, equipment, chattels and facilities of the

17.13     Extended Meanings
          -----------------

          "Hereof", "herein", "hereunder" and similar expressions used anywhere
in this Lease relate to the whole of this Lease and not to any particular
section or subsection, unless otherwise expressly provided. The use of the
neuter singular pronoun to refer to the Landlord or the Tenant is deemed a
proper reference even though the Landlord or the Tenant is an individual,
partnership, corporation or a group of two (2) or more individuals, partnerships
or corporations. The necessary grammatical changes required to make the
provisions of this Lease apply in the plural sense where there is more than one
(1) landlord or tenant and to either corporations, associations, partnerships or
individuals, males or females, shall in all instances be assumed as though in
each case fully expressed.

17.14     No Transfer on Bankruptcy
          -------------------------

          Neither this Lease nor any interest of the Tenant herein nor any
estate hereby created will pass or enure to the benefit of any trustee in
bankruptcy or any receiver or any assignee for the benefit of creditors of the
Tenant or otherwise by operation of law.

17.15     Successors Bound
          ----------------

          All rights and liabilities herein given to, or imposed upon, the
respective parties hereto shall extend to and bind the several respective heirs,
executors, administrators, successors and assigns of the said parties and if
there is more than one (1) party described in Section l.l(b), they shall all be
bound jointly and severally by the terms, covenants and agreements herein on the
part of the Tenant. No rights, however shall enure to the benefit of any
assignee of the Tenant unless the assignment to such assignee has been first
approved by the Landlord. All covenants, agreements, stipulations, obligations
and other provisions of this Lease to be observed, performed and kept by the
Tenant shall run with the land and therefore be enforceable by all the
successors of the Landlord.
