(b) Lessee shall not be entitled to any abatement, compensation, reduction of or set-off against any rental payments due, including, but not limited to, abatements, compensations, reductions, counterclaims or set-offs due or alleged to be due to Lessee from Lessor, or by reason of any past, present, or future claims of Lessee against Lessor under this lease or otherwise; nor shall this lease terminate, or the respective obligations of Lessor or Lessee be otherwise affected by reason of defect in, or damage to, or loss of possession, or loss of use of or destruction of the Collateral from whatever cause, the prohibition or the restriction of Lessee's use of the Collateral, the interference with such use by any private person or entity, or for any other cause, whether similar or dissimilar to the foregoing, any present or future law to the contrary notwithstanding: it being the intention of the parties hereto that the rental amounts due pursuant to each Schedule and other amounts payable by Lessee hereunder shall continue to be payable in all events in the manner and at the times provided in each Schedule unless the obligation to pay the same shall be terminated pursuant to the express provisions of this lease or any Schedule hereto. 3. TERM. Notwithstanding the date of delivery of the Collateral specified in each Schedule, the term of this lease shall, with respect to the Collateral described in each Schedule, commence at the date and continue for the term specified in such Schedule. 4. USE. Lessee shall not, without prior written consent of Lessor, change the location of the Collateral from that specified in the Schedule nor change the use of the Collateral to any use which could in any way result in a change of capital cost allowance class from that specified in the Schedule. The Collateral shall be used by the Lessee for commercial, industrial, professional or handicraft purposes only. The Lessee shall not affix the Collateral to real or immovable property nor to any goods, chattels, or movable property not otherwise leased hereunder without the prior written consent of the Lessor. 5. ORDER, DELIVERY, INSTALLATION. Order, delivery and installation of the Collateral shall be entirely at the Lessee's risk and expense and shall be arranged by the Lessor on behalf of and as agent for the Lessee in a manner and upon terms and conditions according to the Lessee's written instructions and, to the extent such instructions are not provided , according to the Lessor's sole discretion but still at the Lessee's risk and expense. The Lessee hereby indemnifies and covenants to save harmless the Lessor from and against all claims and liabilities howsoever arising out of or in connection with such order, delivery and installation including but not limited to delays in or refusal to accept delivery. 6. TITLE. The Lessor shall at all times have and retain whatever title to the Collateral is acquired by the Lessor from the seller or manufacturer of the Collateral. The Lessee shall have no right, title or interest in the Collateral other than the right of possession and use in accordance with the terms hereof and the right conferred by paragraph 15 hereof. The Lessee acknowledges that the Collateral is and shall remain personal or movable property. 7. WARRANTIES. Lessee has selected the Collateral and the seller thereof. Lessee acknowledges that the Lessor has made no representation or warranty with respect to the Collateral, its condition, design, durability, operation, suitability or fitness for the use intended by the Lessee, its freedom from liens and encumbrances, the Lessor's good title thereto, or as to any other matter or thing whatsoever and all warranties whether express or implied are, to the extent permitted by law, hereby excluded. Lessee shall unconditionally and without set-off or compensation pay the rent stipulated in each Schedule even if the Collateral does not operate as intended by the Lessee, or at all, or as represented by the manufacturer or the seller or the Collateral operates or fails to operate or performs in a manner that could give rise to a fundamental breach of contract or is unacceptable for any other reason whatsoever. Lessor shall not be liable to the Lessee for any loss, cost, damage or expense of any kind or nature caused directly or indirectly by the Collateral or the use, ownership or maintenance thereof or for any loss of business or other damages whatsoever and howsoever caused. Lessor hereby assigns to Lessee for the term hereof only all assignable rights under any warranty given to the Lessor by the seller or manufacturer of the Collateral, and at Lessee's expense, agrees to co-operate reasonably with Lessee in the enforcement of any such warranties. 8. REPAIRS. The Collateral shall be at the risk of the Lessee who shall maintain, repair, overhaul, service and keep the Collateral in a good and substantial manner and shall maintain the Collateral in a condition equivalent to its condition at the commencement of this lease, fair wear and tear only excepted and in a fully operative condition in conformity with any recommendations for maintenance or otherwise which may from time to time be made by any manufacturer or seller of the Collateral and in conformity with all applicable laws, orders, rules, regulations and directives of any government departments, boards or authorities. In the event of loss, damage or destruction to or of the Collateral, Lessee shall immediately give notice to the Lessor of such loss, damage or destruction and Lessee shall at the Lessor's option forthwith repair or replace the Collateral with similar equipment of equivalent value. All parts, mechanisms and devices added to the Collateral whether by way of repair, alteration, addition or improvement shall immediately become property of Lessor and part of the Collateral for all purposes hereof. 9. INSURANCE. Lessee shall obtain, and maintain for the entire term of this lease, at its own expense, property damage and liability insurance and insurance against loss or damage to the Collateral including without limitation, loss by fire, (including extended coverage) theft, collision and such other risks of loss as are customarily covered by insurance on the type of Collateral leased hereunder and 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. The amount of insurance covering damage to or loss of the Collateral shall not be less than the greater of the full replacement value of the Collateral or the installments of rent then remaining unpaid hereunder. Each insurance policy will name Lessee and Lessor as insureds, will name Lessor as loss payee thereof, and shall contain a clause requiring the insurer to give to Lessor at least 30 days prior written notice of any alteration in the terms of such policy or the cancellation thereof. Lessee shall furnish to Lessor a certificate of insurance or other evidence satisfactory to Lessor that such insurance coverage is in effect, provided, however that Lessor shall be under no duty either to 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. Lessee further agrees to give Lessor prompt notice of any damage to or loss of the Collateral or any part thereof. Lessee will at its expense make all proofs of loss and take all other steps necessary to recover insurance benefits, unless advised in writing by Lessor that Lessor desires so to do, at Lessee's expense. Proceeds of insurance will be disbursed by Lessor against satisfactory invoices for repair or replacement of Collateral, provided this lease not then be in default. Performance by Lessee under this paragraph will not affect or release Lessee's obligations and liabilities herein elsewhere provided. 10. LESSEE'S COVENANTS. The Lessee covenants with the Lessor: (a) that the Lessor or its agents shall have the right at all reasonable times to fully inspect the Collateral and any parts thereof, or any documents relating thereto, to determine the condition of the Collateral, and to further determine whether or not the Lessee is performing according to the covenants and conditions herein contained or for any other purpose; (b) to operate, use and maintain the Collateral at all times and to maintain all records, logs and other materials in conformity with all the applicable laws, orders, rules, regulations and directives of governmental departments, boards or authorities, and in conformity with any limitations or restrictions of performance or any published instructions and specifications which may from time to time be recommended by the manufacturers or sellers of the Collateral; (c) not to use or operate the Collateral or permit it to be used or operated illegally or contrary to any applicable laws, regulations, orders, rules or directives of any power or government or agency thereof having jurisdiction, or contrary to any terms of any insurance policy in force in connection with the Collateral or in any way other than in a careful and prudent manner and to indemnify and hold the Lessor harmless from and against any and all actions, claims, demands, prosecutions, administrative proceedings and any similar assertions or threats in any way arising out of the custody, use, or operation of the Collateral during the term of this lease, and to assume liability and pay for any and all transgressions, defaults, fines, penalties or forfeitures incurred, suffered or assessed against the Lessor or the Lessee during the term of the lease together with all legal fees, costs and expenses incidental to the foregoing to the complete exoneration of the Lessor;

provided that upon payment of such fees, assessments, taxes or levies, the Lessee will immediately deliver the receipts for such payments to the Lessor, and that if the Lessor pays (which it may, but is not obliged to do) any sum or sums which is an obligation of the Lessee under this lease, then the amount of such payments shall be forthwith payable by the Lessee to the Lessor and if not so paid shall bear interest from the date such payment is due at the Prime Rate plus 3% per annum calculated and compounded monthly; (g) to furnish at its own cost and expense all fuel, oils, lubricants and other material necessary for the operation and maintenance of the Collateral; (h) to indemnify and save the Lessor harmless from and against all costs, claims, demands, expenses, liabilities, awards, actions and causes of action for loss or damage or injury (including death) of persons or property or of any other nature and kind whatsoever arising from this lease or in any way relating to the use, operation or ownership of the Collateral during the term of this lease and whether caused by Lessee's negligence or otherwise including without limitation, the manufacture, selection, purchase, character, safety, condition, delivery, refusal by the Lessee to accept delivery, possession, operation, sale, storage or return of the Collateral;

Provided that the Lessor may, by notice given to the Lessee on or prior to the termination of this lease, require the Lessee at its expense to dispose of the Collateral upon termination in such manner as the Lessor may reasonably request. 12. DEFAULT. The occurrence or happening of any one or more of the following events shall constitute an event of default: (a) the Lessee shall fail to make any rent payment or other payments required hereunder when due and such failure shall continue unremedied for a period of 20 days after written notice by Lessor; or (b) the Lessee removes the Collateral from its place of location stated on the Schedule without the Lessor's prior written consent; or (c) the Lessee parts with possession of the Collateral; or (d) the Lessee purports to sell, assign, transfer, sublet, pledge, hypothecate or otherwise suffer a lien, encumbrance or other adverse claim of any kind upon or against any interest in this lease or the Collateral without the Lessor's prior written consent; or (e) the Collateral is put to abnormal use likely to result in accelerated depreciation; or (f) the Lessee shall fail to perform or observe any covenant, condition or agreement to be performed or observed by it hereunder and such failure shall continue unremedied for a period of 20 days after written notice thereof by Lessor; or (g) any representation or warranty made by Lessee herein or in any document or certificate furnished Lessor in connection herewith or pursuant hereto shall prove to be incorrect at any time in any material respect; or (h) the Lessee or any Indemnifier shall become insolvent or bankrupt or make an assignment for the benefit of creditors or consent to the appointment of a trustee or receiver; or a trustee or a receiver shall be appointed for Lessee or any Indemnifier or for a substantial part of any of their property without consent and shall not be dismissed within a period of 30 days; or bankruptcy, reorganization or insolvency proceedings shall be instituted by or against Lessee or any Indemnifier and if instituted shall not be dismissed within a period of 30 days; or (i) if the Collateral or any material part thereof is seized under legal process, confiscated, sequestered or attached or if a distress is levied thereon; or (j) if Lessee or any Indemnifier is a corporation and (i) the control or beneficial ownership thereof changes from that which existed at the date of execution of this lease; (ii) any special resolution is passed or other proceedings taken regarding the wind-up of the corporation; (iii) it ceases to carry on the business presently conducted by it; or (k) the Lessee or any Indemnifier shall suffer the loss or suspension of any licences, permits, or other operating authorities required for the present operation of its business or any part of it; or (l) the Lessee defaults under any other agreement to which Lessee and Lessor are parties or any Indemnifier defaults under any other agreement to which any Indemnifier and the Lessor are parties; or (m) if the Lessor in good faith believes and has commercially reasonable grounds to believe itself insecure or that the prospect of payment or performance by the Lessee hereunder is about to be impaired or that the Collateral is or is about to be placed in jeopardy. For greater certainty, it is understood and agreed that if any such default shall occur in respect of any Schedule hereunder, such default shall at the option of the Lessor be deemed to be a default under any or all other Schedules hereunder. 13. REMEDIES ON DEFAULT. Upon the occurrence of an event of default the Lessor may: (a) take possession of the Collateral and for that purpose enter any premises where the Collateral is located whether or not the Collateral is affixed to any such premises, and sell, lease or otherwise dispose of the Collateral by public or private means and upon such terms and consideration as the Lessor may in its sole discretion accept. Without limiting the generality of the foregoing, the Lessor shall have the right to dispose of the Collateral where the payment for such is deferred provided that the Lessee will not be entitled to be credited with the proceeds of any such disposition until the monies therefor are actually received. The Lessee hereby waives any damages or claim to damages arising from any retaking of possession under the terms of this lease; or (b) in the name of and as the irrevocably appointed agent and attorney for Lessee and without terminating or being deemed to have terminated this lease take possession of the Collateral and proceed to lease the Collateral to any other person, firm or corporation on such terms and conditions, for such rental and for such period of time as Lessor may deem fit and receive such rental and hold the same and apply the same against any monies expressed to be payable from time to time by Lessee hereunder; or (c) terminate this lease and by written notice to Lessee require Lessee to forthwith pay to Lessor on the date specified in such notice, as a genuine pre-estimate of liquidated damages for loss of a bargain and not as a penalty the present worth of the aggregate of all unpaid amounts due hereunder as rental or otherwise to the expiration of the term of the lease (as if the lease had not been terminated) calculated by discounting such amounts at 5% per annum compounded monthly less the net amount received by Lessor on any sale, lease or other disposition of the Collateral after deducting all costs and expenses including legal fees and disbursements on a solicitor and own client basis. No one or more of the remedies referred to herein is intended to be exclusive, but each shall be cumulative and in addition to any other remedies referred to herein or otherwise available to the Lessor at law or in equity, and in particular pursuant to the Personal Property Security Act of any Province or Territory in Canada in force or to come into force from time to time as the same may be proclaimed in force, amended or replaced by similar legislation from time to time. If upon any disposition of the Collateral under the provisions of this lease or under the provisions of any other remedies so available to the Lessor there shall be any surplus, such surplus shall be the sole and absolute property of the Lessor. 14. WAIVER/SEVERABILITY. Any provision of this lease which is unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition without invalidating the remaining provisions hereof and any such prohibition in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Lessee, if a corporation, agrees that The Limitation of Civil Rights Act of the Province of Saskatchewan, or any provision thereof, shall have no application to this lease or any agreement or instrument renewing or extending or collateral to this lease and the Lessee acknowledges that seizure or repossession of the Collateral shall not by implication of law extinguish the Lessee's indebtedness under this lease or other collateral security. 15. OPTION TO PURCHASE. Provided the Lessee shall not be in default under any obligation on its part hereunder, the Lessor hereby grants to the Lessee an option to purchase the Lessor's interest in the Collateral herein for the purchase price and at the time set forth in the Schedule or Schedules attached hereto. The option granted herein shall be exercised by the Lessee giving the Lessor written notice of its intention to exercise the option at least 30 days prior to the time set forth in the Schedule. The time set forth in the Schedule shall be the time for the conclusion of the sale, and on that date the Lessee, having exercised such option, shall pay the purchase price to the Lessor and the Lessor shall transfer its interest in the Collateral to the Lessee whereupon this lease shall cease with respect to such Collateral. The Lessee shall pay any and all Provincial or Federal taxes, licence or registration fees or other fees, costs or charges payable in respect of the Collateral and in connection with any said sale and purchase. The bill of sale or sale agreement from the Lessor to the Lessee shall contain no warranties on the part of the Lessor either express or implied, except that the Lessor shall warrant that it has done no act or created any security interest in the Collateral which would adversely affect the title thereto. 16. INDEMNITIES SURVIVE. The indemnities provided by the Lessee to the Lessor under this lease, and in particular those under paragraphs 5 and 10 shall survive and continue in full force and effect after termination of this lease, in whole or in part, whether by effluxion of time or otherwise, or the release or discharge from this lease of any Collateral, or the sale or disposition of the Collateral or the release or discharge of the Lessee to pay any rental payments, or as to any act, matter or thing which shall have been done or have occurred or arisen prior to such termination, release or discharge. 17. ENTIRE AGREEMENT. This lease together with each schedule and any purchase authority, purchase order, delivery and/or installation receipt and indemnity given with this lease constitutes the entire agreement between the parties. 18. NON CANCELLABLE LEASE. This lease cannot be cancelled or terminated except as expressly provided herein. 19. PURCHASE MONEY SECURITY INTEREST AND PROCEEDS. This lease grants to the Lessor: (a) a Purchase Money Security Interest in the Collateral unless this lease shall constitute a sale and leaseback of the Collateral; and (b) a Security Interest in Proceeds of the Collateral which are all present and after acquired personal property,fixtures and crops, within the meaning of the Personal Property Security Act of any Province or Territory in Canada in force or to come into force from time to time as the same may be proclaimed in force, amended or replaced by similar legislation from time to time. 20. COPY OF AGREEMENT. The Lessee hereby acknowledges receiving a copy of this lease and waives all rights to receive from the Lessor a copy of any financing statement, financing statement (transition), financing change statement or verification statement filed at any time in respect of this lease. 21. FURTHER ASSURANCES. The Lessee shall forthwith and from time to time execute all documents and do all acts and things which in the opinion of the Lessor are necessary or desirable to provide continuing rights and priorities in the Collateral, to provide a security interest, a purchase money security interest, and a security interest in proceeds of the Collateral as the case may be. 22. PPSA WORDS AND EXPRESSIONS. Words and expressions used herein that have been defined in the Personal Property Security Act of any Province or Territory of Canada in force or to come into force from time to time as the same may be amended or replaced by similar legislation from time to time shall be interpreted in accordance with their respective meanings given in any such Act unless otherwise defined herein or unless the context otherwise requires. 23. INDEMNIFIER. When used in this lease, "Indemnifier" means any individual or corporation which provides any guaranty or indemnity agreement of any kind to the Lessor to secure the obligations of the Lessee to the Lessor. 24. GOVERNING INSTRUMENT. In the event of any conflict between any provision in this lease and any provision in any Schedule hereto, the provision of such Schedule shall prevail. 25. QUEBEC. Where this lease is governed by the laws of Quebec, this lease shall be construed as a contract of leasing, governed by articles 1842 to 1850 of the CIVIL CODE OF QUEBEC, and (a) for greater certainty, the word "lease" as used herein and in any Schedules or forms related shall be read as "contract of leasing" or "leasing", as the context requires; (b) the security interests granted in sections 1 and 19(b) hereof shall be in the nature of a moveable hypothec for that sum disclosed as the total in item 1 of the Schedule(s) Annexed, with interest at the rate of 24% per annum from the date hereof. 26. MISCELLANEOUS. (a) The parties agree that time is of the essence hereof and that no waiver by Lessor of any default nor any compromise or extension of payment granted by Lessor shall constitute a waiver of any other default by the Lessee or shall be a waiver of any other right of Lessor. (b) This lease may be amended but only in writing signed by the parties hereto. (c) The captions in this lease are for convenience only and shall not define or limit any of the terms hereof. (d) This lease shall be binding upon and enure to the benefit of the parties hereto, their permitted heirs, executors, administrators, successors and assigns.

(f) "Prime Rate" means the floating annual rate of interest established and recorded by HSBC Bank Canada from time to time as a reference rate for purposes of determining rates of interest it will charge on loans denominated in Canadian dollars. (g) Where there shall be more than one Lessee, they shall be jointly and severally bound to the fulfilment of their obligations hereunder. (h) If the context so requires, words importing number shall be deemed to include a greater or lesser number, words importing gender shall be deemed to include the other gender or the body corporate and words importing the body corporate shall be deemed to include either gender. (i) The Lessor and the Lessee confirm that they have expressly required that this lease and all other schedules, purchase orders, notices and documents relating thereto be drafted in English.
