The Landlord may from time to time re-estimate any items of Additional Rent and may fix monthly instalments for the then remaining balance of the Fiscal Year so that such items will be entirely paid during such Fiscal Year.

	(b)	Within a reasonable period of time after all information necessary to calculate actual Additional Rent becomes available after the end of each Fiscal Year, the Landlord will provide to the Tenant a written statement (in this Section 5.5 referred to as the "Statement") setting out in reasonable detail the amount of Operating Costs, the Property Taxes and such other items of Additional Rent as the Landlord had estimated in advance for such Fiscal Year. If the Tenant’s share of Property Taxes, the Tenant’s share of Operating Costs (being its Proportionate Share subject to Section 6.7) and other items of Additional Rent actually paid by the Tenant to the Landlord during such Fiscal Year differs from the amount of the Tenant’s share of Property Taxes, the Tenant’s share of Operating Costs and other items of Additional Rent payable for such Fiscal Year, the Tenant shall pay such difference or the Landlord shall credit the Tenant's account (as the case may be), without interest within 30 days after the date of delivery of the Statement. The respective obligations of the Landlord and the Tenant in this Section 5.5(b) shall survive the end of the Term or earlier termination of this Lease.

	(c)	The Tenant shall not claim a re-adjustment in respect of Operating Costs or Property Taxes or other items of Additional Rent estimated by the Landlord or the share payable by the Tenant on account thereof for any Fiscal Year except by notice given to the Landlord within six months after delivery of the Statement, stating the particulars of the error in computation.

	(d)	If the Tenant disputes the accuracy of any Statement within the period permitted under Section 5.5(c) above and the Landlord and the Tenant fail to settle the matter within a reasonable period, the matter shall be referred by the Landlord to an Expert for prompt determination. The Tenant shall pay in accordance with the Statement until such decision is rendered. The Expert’s signed determination shall be final and binding on both the Landlord and the Tenant. Any adjustment required to any previous payment made by the Tenant or the Landlord by reason of any such determination shall be made within 14 days thereof, and the party required to pay such adjustment shall bear all costs of the Expert, except that if the amount to be paid is 20% or less of the amount in dispute, the Tenant shall pay all such costs.

~~5.6 •Rent Deposit~~

The Landlord acknowledges receipt from the Tenant of the Rent Deposit to be applied to the Rent as it becomes due or as otherwise provided in Section 1.1(k)(i) and, to the extent it is not so applied from time to time, to be held, without interest, as security (without prejudice to the Landlord’s other rights and remedies) for the observance and performance of the Tenant’s obligations under this Lease.•

5.7 Security Deposit

The Landlord acknowledges receipt from the Tenant of the Security Deposit to be held, without interest, as security (without prejudice to the Landlord’s other rights and remedies) for the observance and performance of the Tenant’s obligations under this Lease. If the Tenant defaults in the performance of any of the terms, covenants, conditions and provisions of this Lease as and when the same are due to be performed by the Tenant, then the Landlord, at its option, may appropriate and apply all or any part of the Security Deposit on account of any losses or damages sustained by the Landlord as a result of such default. Upon demand by the Landlord following any such appropriation, the Tenant shall pay to the Landlord an amount sufficient to restore the total original amount of the Security Deposit. If the Tenant complies with all of the terms, covenants, conditions and provisions under this Lease, the Security Deposit shall be returned to the Tenant without interest within 90 days after the expiry or earlier termination of the Term, or, at the Landlord's option, shall be applied by the Landlord on account of the last month's Rent. Notwithstanding the foregoing, if the Tenant fails to execute and deliver this Lease within 5 days of receipt from the Landlord or fails to take possession of the Premises by the Commencement Date, the Landlord may, at its sole option, terminate this Lease, whereupon the Security Deposit shall be retained by the Landlord as liquidated damages on account of the Tenant’s default and not as a penalty.

5.8 Net Lease

The Tenant acknowledges and agrees that it is intended that this Lease shall be a completely carefree net lease for the Landlord and that the Landlord shall not be responsible for any costs, charges, expenses and outlays of any nature whatsoever arising from or relating to the Premises during the Term, whether foreseen or unforeseen and whether or not within the contemplation of the parties at the commencement of the Term, except as shall be otherwise expressly provided in this Lease.

However, in effecting such entry the Landlord shall use reasonable efforts to minimize interference with the Tenant’s use and enjoyment of the Premises, and the Landlord shall endeavour to give the Tenant at least twenty-four (24) hours’ prior notice before doing any repair or maintenance work (other than in the case of an emergency or apprehended emergency).

8.6 Relocation

The Landlord shall have the right, in its sole discretion, from time to time, on not less than 60 days’ written notice to the Tenant, to relocate the Premises to other premises within the Project having approximately the same area as the Premises. The Landlord shall be entitled to designate the location of the new premises and the date by which the Tenant must relocate to the new premises, and such location and date shall be specified in the written notice. As of the date so specified, the Tenant’s right to use and occupy the Premises will terminate, whether or not the Tenant has moved, unless the Landlord has in its sole discretion by another notice in writing extended such date. The Tenant shall on the date set out in the notice from the Landlord relocate to the other premises and vacate the Premises, and the provisions of Section 9.3 shall apply in respect of the Premises on such date.

If the Landlord relocates the Tenant after occupancy of the Premises by the Tenant, the Landlord shall provide the relocated premises improved to a standard and using materials of approximately the same quality as the Leasehold Improvements which exist in the existing Premises at the time of relocation and will reimburse the Tenant (upon receipt of copies of receipted third party invoices) for direct costs associated with the relocation, including, without limitation, moving costs, reprinting of a limited supply of stationery and supplies and disconnection and reconnection of telephone and computer equipment and systems. In no case will the Tenant be reimbursed or compensated for indirect costs including overhead, overtime charges or loss of profits and the Tenant will minimize costs by re-using all fixtures and trade fixtures from the Premises where it is feasible to do so. The Landlord agrees to use reasonable efforts to effect the relocation with a minimum of disruption to the Tenant’s business. The Landlord and the Tenant shall enter into a lease amending agreement in the Landlord's standard form to confirm the terms of the relocation including, without limitation, any adjustment to the Basic Rent if the Rentable Area of the relocated premises is different than the Rentable Area of the existing Premises and to confirm that all other terms and conditions of this Lease shall apply with respect to the relocated premises for the remainder of the Term.

9.2 Alterations by Tenant

The Tenant may from time to time at its own expense install Leasehold Improvements and alter existing Leasehold Improvements (the "Alterations") provided that:

(a)

all Alterations shall require the prior written approval of the Landlord, which approval may be withheld or conditioned by the Landlord in its sole discretion, save and except for minor

		alterations to Leasehold Improvements which do not affect the structure of the Building or Project, any exterior walls, windows or roof, any of the Building Systems or the aesthetics of the Building or Project and which do not require a building permit, provided the Tenant has given written notice with reasonable detail of the proposed Alterations to the Landlord in advance;

	(b)	for Alterations which require the Landlord's approval, the Tenant shall furnish the Landlord with two complete sets of professionally prepared working drawings (which shall include any architectural, structural, electrical, mechanical, computer system wiring and telecommunication plans) of the proposed Alterations. The Tenant shall retain the Landlord’s base building mechanical, electrical and structural engineering consultants to ensure compatibility of the Building Systems and the Alterations. If the Tenant uses other consultants for the preparation of the Tenant’s working drawings, then the Landlord may elect to retain architects and engineers to review such working drawings for the purpose of approving the proposed Alterations (it being understood that notwithstanding such approval, the Landlord shall have no responsibility with respect to the adequacy of such working drawings). The Tenant shall pay to the Landlord, on demand, the costs of the examination of such drawings by either the Landlord or an outside consultant plus an administration fee of 15% of such costs;

	(c)	the Alterations shall be subject to regulation, supervision, control and inspection by the Landlord and, in addition to any other payment contained in this Article, the Tenant shall pay to the Landlord, on demand, the Landlord’s then current fee for coordination services provided by the Landlord during the Tenant’s construction of its Alterations;

	(d)	the Tenant shall provide, prior to the commencement of Alterations, evidence of required workers compensation coverage and proof of owner and contractors protective liability insurance coverage, with the Landlord, any property manager and any Mortgagee as required by the Landlord, to be named as additional insureds, in amounts, with insurers, and in a form satisfactory to the Landlord, which shall remain in effect during the entire period in which the Alterations will be carried out. In addition, if requested by the Landlord, the Tenant shall provide proof of performance and payment bonds being in place;

	(e)	the Tenant will deliver a list identifying every contractor and subcontractor, accompanied by an up-to-date valid clearance certificate for each of them issued by the appropriate workers compensation, safety and insurance authority and the Landlord shall have approved, prior to commencement of the Alterations, such contractors and subcontractors and their respective labour affiliations. The Tenant will not use any contractor or permit the use of any sub-contractor that is not identified on the list;

	(f)	if any proposed Alterations could affect the structure, the floors, the ceiling, the roof, the beams or columns, the exterior walls or the Building Systems, the Landlord may in its sole discretion require that any such Alterations be performed by either the Landlord or its contractors in which case the Tenant shall pay the Landlord's cost plus an administration fee of 15%;

	(g)	the Tenant shall have provided to the Landlord a copy of the contract for the Alterations and evidence satisfactory to the Landlord as to the existence of all necessary permits;

	(h)	the Tenant shall perform the Alterations or cause the Alterations to be performed: (i) in accordance with any construction methods and procedures manual for the Building or Project; (ii) in accordance with the plans and specifications submitted to and approved in writing by the Landlord; (iii) in accordance with any conditions, regulations, procedures or rules imposed by the Landlord; (iv) in compliance with all Applicable Laws; and (v) in a good and workmanlike and expeditious manner using new materials;

	(i)	the Landlord may inspect construction as it proceeds;

	(j)	upon completion of the Alterations, the Tenant shall provide the Landlord with a complete set of "as built" drawings in hard copy and AutoCad format for the Alterations; and

	(k)	if the Tenant fails to observe any of the requirements of this Article, the Landlord may in its sole discretion require that construction stop and, at the Landlord’s option, that the Premises be restored to their prior condition failing which the Landlord may do so and the Tenant shall pay the Landlord's cost plus an administration fee of 15%.

9.3 Removal of Improvements and Fixtures

All Leasehold Improvements shall immediately upon their placement become the Landlord's property without compensation to the Tenant. Except as otherwise directed by the Landlord in writing, no Leasehold Improvements or trade fixtures shall be removed from the Premises by the Tenant either during or at the expiry or earlier termination of the Term except that:

(a)

the Tenant may, during the Term, in the usual course of its business, remove its trade fixtures, provided that the Tenant is not in default under this Lease; and

(b)

the Tenant shall, at its sole cost do the following (the "Restoration"): (i) remove all of its trade fixtures; and (ii) remove such of the Leasehold Improvements and wiring, cables and related devices and equipment and restore the Premises and any other part of the Project affected thereby to the then current base building standard of the Building as established by the Landlord from time to time, all as the Landlord shall require by notice prior to the expiration of the Term. Such Restoration shall be completed by the date (the "Restoration Date") that is the later of: (A) the end of the Term; and (B) 15 days after the Landlord's notice, provided that in the event of termination of this Lease prior to the expiry of the Term, such Restoration shall be completed no later than 15 days after the date the Landlord recovers possession of the Premises. Despite the foregoing the Tenant shall leave in place and in an unimpaired condition such Leasehold Improvements and wiring, cables and related devices and equipment as the Landlord may by notice in writing direct, if any.

The Tenant shall at its own expense repair any damage caused to the Project by the Leasehold Improvements, trade fixtures or wiring, cables and related devices and equipment and/or such Restoration. If the Tenant does not remove its trade fixtures, or wiring, cables and related equipment prior to the expiry or earlier termination of the Term, such trade fixtures or wiring, cables and related devices and equipment shall, at the option of the Landlord, be deemed abandoned and become the property of the Landlord and may be removed from the Premises and sold or disposed of by the Landlord in such manner as it deems advisable and the Tenant shall pay to the Landlord on demand all costs incurred by the Landlord in connection therewith, plus an administration fee of 15% of the costs. The Tenant at the end of the Term shall peaceably surrender and yield up possession of the Premises to the Landlord in as good a condition, repair and decoration as that in which the Tenant is required to maintain the Premises throughout the Term (including as provided for in Section 9.1), shall return to the Landlord at the Landlord’s management office for the Project all keys and other entry devices for the Premises and the Project which are in the possession of the Tenant, and shall inform the Landlord of all combinations of locks, safes and vaults, if any, that will remain in the Premises. If the Tenant fails to complete any work or effect any of the other matters referred to in this Section within the period specified, the Tenant shall pay compensation to the Landlord for damages suffered by the Landlord for loss of use of the Premises, which damages shall not be less than double the per diem Rent payable during the last month preceding the expiry or earlier termination of the Term (or which would have been payable but for any discount or rent-free period applicable to such last month). Further, if the Tenant does not complete the Restoration by the Restoration Date the Landlord may carry out such Restoration and the Tenant shall pay to the Landlord the cost of the Restoration plus an administration fee of 15%. The Tenant’s obligations in this Section 9.3 shall survive the end of the Term or earlier termination of this Lease.

9.4 Liens

The Tenant shall pay before delinquency for all materials supplied and work done in respect of the Premises so as to ensure that no lien or claim of lien is registered against any portion of the Lands or Project or against the Landlord's or Tenant's interest in the Lands or Project. If a lien or claim of lien is registered or filed, the Tenant shall discharge it at its expense within five Business Days after notice from the Landlord (or sooner if such lien or claim is delaying a financing or sale of all or any part of the Project), failing which the Landlord may at its option discharge the lien or claim of lien by paying the amount claimed to be due into court and the amount so paid and all expenses of the Landlord including legal fees (on a solicitor and client basis) shall be paid by the Tenant to the Landlord. The Tenant shall not mortgage, charge, grant a security interest in or otherwise encumber any Leasehold Improvements.

9.5 Notice by Tenant

The Tenant shall promptly notify the Landlord of any accident, casualty, defect, damage or deficiency which occurs or exists in any part of the Project and which comes to the attention of the Tenant.

ARTICLE 10 - USE OF PREMISES

10.1 Permitted Use

The Tenant shall continuously use the whole of the Premises only as a commercial business office, which the Tenant shall operate in a first-class, reputable manner befitting the reputation and image of the Building, and for no other purpose. The Tenant shall not use the Premises in a manner which does or could result in excessive demands being placed on the Building Systems or other Common Areas and Facilities.

10.2 Compliance with Laws

The Tenant shall use and occupy and shall cause the Premises to be used and occupied in compliance with all Applicable Laws and in a safe, careful and proper manner. It is the Tenant’s responsibility to ensure that its use from time to time is permitted by all Applicable Laws. At the Landlord's request the Tenant shall comply with any directive, policy or request of any governmental or quasi-governmental authority or any other reasonable request of the Landlord, in respect of any energy conservation, waste management, safety, security or other matter relating to the operation of the Project. If due primarily to the Tenant's use or occupancy of the Premises, improvements or changes are necessary to comply with any Applicable Laws or with any such directive, policy or request or with the requirements of insurance carriers, the Landlord may at its option either do the necessary work, at the expense of the Tenant, or forthwith give notice to the Tenant to do such work within the requisite period of time and the Tenant shall then do such work within the requisite period of time. The Tenant shall pay to the Landlord the costs of any such work done by the Landlord, together with an administration fee of 15%.

10.3 Nuisance, Interference, Waste, Overloading

The Tenant shall not cause or allow any act or thing which constitutes a nuisance or which is offensive to the Landlord or other occupants of the Project or which interferes with the operation of any Building Systems or with the computer equipment, telecommunication equipment or other technological equipment of the Landlord, any service providers or other occupants of the Project. The Tenant shall keep the Premises free of debris and other items that might attract rodents or vermin and free of anything of a dangerous, noxious or offensive nature or which could create a fire, environmental, health or other hazard (including any electromagnetic fields or other forms of radiation) or undue vibration, heat or noise. The Tenant shall not cause or allow any overloading of the floors of the Project or the bringing into any part of the Project, including the Premises, of any articles or fixtures that by reason of their weight, use or size might damage or endanger the structure or any of the Building Systems.

10.4 Rules and Regulations

The Tenant shall comply and cause every Person over whom it has control to comply with the Rules and Regulations. The Landlord shall have the right from time to time to make amendments, deletions and additions to such Rules and Regulations. If the Rules and Regulations conflict with any other provisions of this Lease, the other provisions of this Lease shall govern. The Landlord shall not be obligated to enforce the Rules and Regulations and shall not be responsible to the Tenant for failure of any person to comply with the Rules and Regulations. The Rules and Regulations may differentiate between different types of tenants, different parts of the Building or the Project or otherwise. The Landlord agrees that it will not enforce the Rules and Regulations in a manner that is discriminatory to the Tenant.

ARTICLE 11 - INSURANCE, LIABILITY AND INDEMNITY

11.1 Tenant’s Insurance

The Tenant shall effect and maintain from the earlier of the Commencement Date and the date the Tenant begins operating in the Premises, and thereafter during the Term, at its sole cost and expense:

	(d)	Tenant's legal liability insurance for the full replacement cost of the Premises including loss of the use of the Premises;

	(e)	business interruption insurance for a minimum period of 24 months in an amount that will reimburse the Tenant for direct or indirect loss of earnings attributable to all perils insured against in Sections 11.1(a) and 11.1(b) or attributable to prevention of access to the premises or the Building as a result of any such perils, including extra expense insurance if applicable; and

	(f)	any other form of insurance that the Landlord or any Mortgagee may require from time to time in form, amounts and for insurance risks acceptable to the Landlord and any Mortgagee.

Should the Tenant fail to maintain any of the insurance required pursuant to this Section 11.1 and should such default continue for two Business Days after notice to the Tenant, then in addition to any other rights and remedies, the Landlord may, but shall have no obligation to, elect to obtain the required insurance and the Tenant shall upon demand pay to the Landlord, as Rent, the Landlord’s cost of obtaining such insurance, together with an administration fee of 15%.

11.2 Form of Tenant Policies

Each policy required pursuant to Section 11.1 shall be in a form and with insurers acceptable to the Landlord, having reasonable deductibles, and: (a) the insurance described in Sections 11.1(a) and 11.1(b) and any other property damage insurance shall include, as additional named insureds (but without liability for premiums) as its interests may appear the Landlord, any Mortgagee and other Persons with an interest in the Project from time to time

designated in writing by the Landlord; (b) the insurance described in Section 11.1(c) shall include as additional named insureds (but without liability for premiums) the Landlord, any Mortgagee, any other Persons with an interest in the Project from time to time designated in writing by the Landlord and any property manager or facilities manager retained by the Landlord in respect of the Project; (c) all property damage and liability insurance shall contain provisions for cross-liability and severability of interests among the Landlord, the other insureds and the Tenant; and (d) all property damage insurance (including boiler and machinery insurance) shall contain a waiver of any rights of subrogation which the insurer may have against the Landlord and those for whom the Landlord is in law responsible whether the damage is caused by the act, omission or negligence of the Landlord or such other Persons.

11.3 Certified Copies and Notice to Landlord

The Tenant shall provide to the Landlord, prior to the earlier of the Commencement Date and the date the Tenant begins operating in the Premises, certified copies or other evidence satisfactory to the Landlord that the Tenant has obtained all insurance policies required by this Lease and shall provide written evidence of the continuation of such policies not less than ten days prior to their respective expiry dates. Each policy required pursuant to Section 11.1 shall provide that: (a) the insurer must notify the Landlord and any Mortgagee in writing at least 30 days prior to any material change detrimental to the Landlord or any Mortgagee or the cancellation of any such policy; (b) the policy shall not be invalidated in respect of the interests of the Landlord or any Mortgagee or any other additional insureds by reason of any breach or violation of any warranties, representations, declarations or conditions contained in such policy; and (c) the policy shall be non-contributing with, and shall apply only as primary and not excess to any other insurance available to all and any of the Landlord, any Mortgagee or any other additional insured referred to above.

11.4 Landlord's Insurance

The Landlord shall effect and maintain during the Term: (a) liability insurance; (b) "all risks" property insurance; (c) boiler and machinery insurance; and (d) such other insurance on the Building and all property and interest of the Landlord in the Building as determined by the Landlord, in each case, to the extent, with coverage and in amounts as determined by the Landlord from time to time. However, despite any other provision of this Lease, as long as Sun Life Assurance Company of Canada or an affiliate thereof (as the term "affiliate" is defined in the Canada Business Corporations Act or the Insurance Companies Act (Canada)) is the Landlord, the Landlord may self-insure, in whole or in part, in respect of any and all casualties; in that event upon the request of the Tenant from time to time the Landlord will furnish a statement as to the perils in respect of which and the amounts to which it has insured the Project and the improvements and installations in the Premises, and also of the perils and amounts as to which the Landlord is self-insuring the Project and the improvements and installations in the Premises.

11.5 Insurance Risks

The Tenant shall not do, omit to do, or permit to be done or omitted to be done upon the Premises or any other portion of the Project anything that may contravene or be prohibited by any of the Landlord’s insurance policies in force from time to time covering or relevant to any part of the Project or which would prevent the Landlord from procuring such policies with companies acceptable to the Landlord. If the occupancy of the Premises, the conduct of business in the Premises or any acts or omissions of the Tenant in the Premises or any other portion of the Project causes or results in any increase in premiums for any of the Landlord’s insurance policies, then, without limiting any other rights or remedies of the Landlord, the Tenant shall pay any such increase and a 15% administration fee thereon as Additional Rent forthwith upon receipt of the invoices of the Landlord for such additional premiums. A written report by an Expert at the Tenant’s sole cost concerning the cause of any increase in premiums will be accepted as conclusive evidence of the cause for the purposes of determining the Tenant's liability to pay for increases as Additional Rent. If the Landlord has chosen to self-insure, the Tenant will pay to the Landlord, as Additional Rent forthwith upon receipt of the invoices of the Landlord setting out reasonable particulars, the charges that otherwise would have been payable under this subsection (including the 15% administration fee thereon) had the Landlord not chosen to self-insure.

11.6 Release of Landlord

The Tenant hereby releases the Landlord from any and all claims, actions, causes of action, damages, demands for damages and other liabilities, howsoever arising, that may be made by the Tenant against the Landlord under the provisions of this Lease to the extent of all insurance proceeds paid under the policies of insurance maintained by the Tenant or which would have been paid if the Tenant had maintained the insurance required under this Lease and had diligently processed any claims thereunder. In addition and without limitation, the Tenant agrees that the Landlord, regardless of negligence or alleged negligence on the part of the Landlord or any breach of the Lease by the Landlord and, notwithstanding anything else herein contained, shall not be liable for and hereby releases the Landlord from:

(a)	any and all claims, actions, causes of action, damages, demands for damages and other liabilities:

	(i)	for or related to any bodily injury, personal injury, illness or discomfort to or death of the Tenant or any of its agents, officers, contractors, employees, invitees, licensees and any other Person for whom the Tenant is legally responsible in or about the Project or the Premises; and

	(ii)	for or related to any loss or damage to property owned by the Tenant or by others and for which property the Tenant is responsible in or about the Project or the Premises, and, without limiting the foregoing, the Landlord shall not be liable for any damage caused by

steam, water, rain or snow which may leak into, issue or flow from part of the Project, including the Premises, or from the pipes or plumbing works thereof, or from any other place or for any damage caused by or attributable to the condition or arrangement of any electric or other wiring;

	(b)	any loss or damage caused as a result of any damage, destruction, construction, alteration, expansion, expropriation, reduction, repair or reconstruction from time to time of the Project, any parts or components of the Project or of improvements on adjoining properties or by anything done or omitted to be done by any other tenant or occupant;

	(c)	any act or omission (including theft, malfeasance or negligence) on the part of any agent, contractor or person from time to time employed by Landlord to perform janitorial services, security services, supervision or any other work in or about the Premises or the Project;

	(d)	any loss or damage, however caused, to books of account, records, files, money, securities, negotiable instruments, papers, computer disks, tapes, software, data and other electronic files and their storage media of any kind or to other valuables of the Tenant including art, artworks, statuary, antiques, gems and precious metals of the Tenant and of others;

	(e)	any loss or damage arising from obstruction of deliveries to or from the Premises or interruption, cessation, faulty operation, breakdown or failure of any Building Systems, including but not limited to, the supply of any utilities, telecommunication services (whether controlled or owned by the Landlord or not) or other services in, to or serving the Project or the Premises, whether they are supplied by the Landlord or by others; and

	(f)	any indirect or consequential damages including, but not limited to, loss of profit.

11.7 Release of Tenant

The Landlord hereby releases the Tenant, and its agents, officers and employees, and any other Person for whom the Tenant is legally responsible from any liability or claim that may be made by the Landlord against the Tenant under the provisions of this Lease with respect to such loss to the extent of the lesser of: (a) the amount, if any, by which such loss exceeds the amount of insurance the Tenant is required to maintain under the terms of this Lease or actually maintains, whichever is greater; and (b) the proceeds actually paid to the Landlord with respect to such loss under the policies of insurance maintained by the Landlord pursuant to Section 11.4 or which would have been paid if the Landlord had maintained the insurance required under this Lease and had diligently processed any claims thereunder. This release shall be operative only if it is not prohibited by the Landlord's insurance policies and would not place the Landlord in breach of such policies or expose the Landlord to additional costs under or in connection with such policies.

11.8 Indemnity by Tenant

The Tenant shall indemnify and save harmless the Landlord from and against any and all claims, actions, causes of action, damages, demands for damages, losses and other liabilities and expenses (including, without limitation, those in connection with bodily injury (including death), personal injury, illness or discomfort or damage to property and legal fees on a solicitor and client basis) due to or arising from or out of all and any of:

	(a)	subject to Section 11.7, any occurrence in, on or at the Premises or the occupancy or use by the Tenant of the Premises or any other part of the Project or occasioned wholly or in part by any act or omission of the Tenant, its officers, employees, agents, contractors, invitees, licensees or by any Person permitted by the Tenant to be on the Premises or the Project or due to or arising out of any breach by the Tenant of this Lease; and

	(b)	any fault, default, negligence, gross negligence, wilful action or omission of the Landlord, its agents, servants, employees or anyone for whom at law the Landlord is liable, which causes interference with or obstruction of deliveries to or from the Premises or interruption, cessation, faulty operation, breakdown or failure of the Building Systems or utilities or services, including but not limited to telecommunication or similar services (whether they are part of the Building Systems or not) and suffered by customers, suppliers or other third parties with whom the Tenant or any occupant of the Premises conducts business or by other Persons who utilize any part of any telecommunications network to which the Tenant or any other occupant of the Project is or are connected.

The Tenant shall not enter into, consent to, or permit any Transfer without the prior written consent of the Landlord, which consent shall be subject to the Landlord's rights under Section 12.2. The Tenant shall pay to the Landlord the Transfer Application Fee in respect of the proposed Transfer. Notwithstanding any statutory provision to the

contrary, it shall not be considered unreasonable for the Landlord to withhold its consent if, without limiting any other factors or circumstances which the Landlord may take into account:

(a)	an Event of Default on the part of the Tenant hereunder has occurred and is continuing, or the Tenant has previously been in material or persistent breach of any of its obligations under this Lease;

(b)	the proposed Transfer would be or could result in violation or breach of any covenants or restrictions made or granted by the Landlord to other tenants or occupants, or prospective tenants or occupants, of the Project;

(c)	in the Landlord's opinion:

	(i)	either the financial background or the business history and capability of the proposed Transferee is not satisfactory;

	(ii)	the nature or character of the proposed business of the proposed Transferee is such that it might harm the Landlord's business or reputation or reflect unfavourably on the Project, the Landlord, or other tenants of the Project, or the image of any of them, or is unethical, immoral or illegal;

	(iii)	the use of the Premises by the proposed Transferee could be incompatible with the other businesses or activities being carried on in the Project or could result in excessive demands being placed on the Building Systems or other Common Areas and Facilities; or

	(iv)	if the Transfer affects less than all of the Premises, the portion affected or the portion remaining are not acceptable in respect of size, access or configuration;

(d)	the proposed Transferee or any principal of the proposed Transferee or any principal shareholder of the proposed Transferee has a history of defaults under other commercial leases or does not have a satisfactory history of compliance with laws;

(e)	the Landlord at the time has, or will have in the next ensuing three month period, other premises in the Project suitable for leasing to the proposed Transferee;

(f)	the basic and additional rent payable by the Transferee is less than the Basic Rent and Additional Rent payable by the Tenant hereunder as at the effective date of the Transfer except in the case where the Landlord determines, in its sole discretion, that payment of lesser rent by the Transferee will not detrimentally affect the leasing program for the Project; or

(g)	the proposed Transfer is to: (i) an existing tenant or occupant of the Project; or (ii) a consulate, embassy, trade commission or other representative of a foreign government; or (iii) a government, quasi-government or public agency, service or office; or (iv) a proposed Transferee whose proposed use is one that the Landlord in its sole discretion determines involves more pedestrian or other traffic than would be usual for an ordinary office use; or (v) a proposed Transferee whose proposed use is one that the Landlord in its sole discretion determines could place on the Building Systems burdens exceeding those which would be usual for an ordinary office use.

Any consent by the Landlord to a Transfer shall not constitute a waiver of the necessity for such consent to any subsequent Transfer.

12.2 Tenant’s Notice, Landlord's Right to Terminate

If the Tenant intends to effect a Transfer the Tenant shall give prior written notice to the Landlord of such intent specifying the identity of the Transferee, the type of Transfer contemplated, the part of the Premises affected and the financial and other terms of the Transfer, and shall provide such financial, business or other information relating to the proposed Transferee and its principals as the Landlord or any Mortgagee reasonably requires, together with copies of all documents which record the particulars of the proposed Transfer. The Landlord shall, within 30 days after having received such notice, the Transfer Application Fee and all requested information, notify the Tenant either that:

	(a)	it consents or does not consent to the Transfer in accordance with the provisions of this Lease; or

	(b)	it elects to terminate this Lease as to the part of the Premises affected by the proposed Transfer, or as to the whole Lease and Premises if the proposed Transfer affects all of the Premises.

If the Landlord elects to terminate this Lease it shall stipulate in its notice the termination date of this Lease, which date shall be the date of possession contemplated under the proposed Transfer (provided that if such date is less than 30 days or more than 90 days following the giving of notice of such election, the Landlord may elect to have the termination date 30 days or 90 days, respectively, following the giving of notice). If the Landlord elects to terminate this Lease, the Tenant may notify the Landlord in writing within ten days following receipt of such notice of the Tenant's intention to refrain from such Transfer and, if the Tenant provides such written notice within such time period, then the Landlord's election to terminate this Lease shall become void. If the Tenant fails to deliver such notice within such time period, then this Lease shall, as to the whole or affected part of the Premises, as the case

may be, be terminated on the date of termination stipulated by the Landlord in its notice of election to terminate. If the Tenant is required to deliver possession of a part only of the Premises, the Tenant shall pay all costs incurred in connection with rendering that part functionally separate and suitable for separate use and occupancy, including partitioning and providing entrances and services.

12.3 Conditions of Transfer

The following terms and conditions apply in respect of a Transfer:

	(a)	if the Transfer is an assignment of this Lease in whole or in part, the Tenant and the Transferee shall execute, prior to the Transfer being made, an agreement with the Landlord in the Landlord’s form including the Transferee’s covenant to be bound by all of the terms of this Lease;

	(b)	notwithstanding any Transfer, the Tenant shall remain liable under this Lease and shall not be released from performing any of the terms of this Lease. The Tenant’s liability shall continue notwithstanding any amendment of this Lease throughout the Term and any exercise of any renewal or extension of the Term provided for herein, regardless of whether or when an amendment of this Lease is made (however the original Tenant’s liability will not be increased by any amendment that it is not a party to) and notwithstanding that the Landlord may collect rent from the Transferee. Without limiting the foregoing, the Tenant shall be responsible for all acts or omissions of any subtenant, licensee or occupant;

	(c)	if the basic and additional rent (net of reasonable out of pocket costs for commissions, for cash allowances and for Alterations required by and made for the Transferee by the Tenant, amortized on a straight line basis over the term of the Transfer) to be paid by the Transferee under such Transfer exceeds the Basic Rent and Additional Rent payable by the Tenant hereunder, the amount of such excess shall be paid by the Tenant to the Landlord. If the Tenant receives from any Transferee, either directly or indirectly, any consideration other than basic rent or additional rent for such Transfer, either in the form of cash, goods or services, the Tenant shall immediately pay to the Landlord an amount equivalent to such consideration;

	(d)	if the Transfer is a sublease, the Transferee will execute a covenant in the Landlord’s form and will agree to waive any statutory or other right to apply to a court or to otherwise elect to: (i) retain the unexpired term of the Lease or the unexpired term of the sublease; (ii) obtain any right to enter into any lease or other agreement directly with the Landlord; or (iii) otherwise remain in possession of any portion of the Premises, in any case where the Lease is terminated, surrendered or otherwise cancelled, including, without limitation, any disclaimer, repudiation, surrender or other termination (each of these transactions being referred to as an "Early Termination") by any trustee in bankruptcy of the Tenant or a Transferee, by any court appointed officer, or by the Tenant or a Transferee in connection with any insolvency proceedings;

	(e)	if there is an Early Termination, the Tenant and any Transferee (except the bankrupt or insolvent Tenant or Transferee) to whom the Landlord gives notice within 60 days after the Early Termination, shall be considered to have entered into a lease with the Landlord on the same terms and conditions as are contained in this Lease except that the term of the lease shall commence on the date of the Early Termination and shall expire on the date this Lease would have expired but for the Early Termination; and

	(f)	notwithstanding the effective date of any permitted Transfer as between the Tenant and the Transferee, all Rent for the month in which such effective date occurs shall be paid in advance by the Tenant so that the Landlord will not be required to accept partial payments of Rent for such month from either the Tenant or the Transferee.

~~12.4 •Corporate Records~~

Upon the Landlord's request, the Tenant shall: (a) deliver a statutory declaration by one of its senior officers setting forth the details of its corporate and capital structure; (b) make available to the Landlord or its representatives all of its corporate or partnership records, as the case may be, for inspection at all times, in order to ascertain whether any Change of Control has occurred; and (c) cause the Indemnifier(s), if any, to provide any of the foregoing in respect of such Indemnifier(s).•

12.5 Permitted Transfers

Notwithstanding Section 12.1 and provided that the Required Conditions are satisfied and there is not then an Event of Default, the Tenant shall have the right on prior written notice to the Landlord, but without being required to obtain the Landlord’s consent, to effect a Transfer in compliance with Section 12.3 in favour of a Permitted Transferee and the Landlord’s right to terminate shall not apply to such a Transfer. For greater certainty and clarity the subletting to the Permitted Transferee known as Savant Explorations Ltd. shall in no manner release the Tenant from any covenant to be observed or performed by it, nor shall the same constitute a waiver, modification or amendment of any of the terms, provisions, covenants or obligations contained in this Lease.

ARTICLE 13 - LANDLORD FINANCING AND STATUS CERTIFICATES

13.1	Subordination and Postponement

	(a)	This Lease and the rights of the Tenant in this Lease shall be subject and subordinate to any and all Mortgages and the Tenant, on request by and without cost to the Landlord, shall, within five Business Days after such request, execute and deliver any and all instruments required by the Landlord to evidence such subordination. Upon request by the Tenant at the time of any request for confirmation of subordination, the Landlord shall make reasonable efforts to obtain from any Mortgagee an acknowledgement and assurance in writing addressed to the Tenant, whereby such Mortgagee acknowledges that, in the event of any such Mortgagee realizing upon the security, it will not disturb the Tenant and will permit the Tenant to remain in possession under this Lease in accordance with its terms, so long as the Tenant is not in default.

	(b)	The Landlord, as to any Mortgage, and a Mortgagee, as to any Mortgage held by it, may, by notice to the Tenant, elect that this Lease and the rights of the Tenant hereunder shall be prior to such Mortgage(s) and the Tenant, on request by and without cost to the Landlord, shall, within five Business Days after such request, execute and deliver any and all instruments required by the Landlord or the Mortgagee, as the case may be, to confirm priority to this Lease over the Mortgage(s).

13.2	Attornment

At any time after any of the following has occurred:

	(a)	if a Mortgagee delivers a notice of attornment;

	(b)	if a Mortgagee shall take possession of the Building or the Premises; or

	(c)	if the interest of the Landlord is transferred to any Person (in this Article referred to as a "Purchaser") by reason of foreclosure or other proceedings for enforcement of any Mortgage, or by delivery of a conveyance,

the Tenant shall, at the option of the Mortgagee or the Purchaser, as the case may be, exercisable by notice in writing to the Tenant, be deemed to have attorned to the Mortgagee or the Purchaser, as the case may be, upon receipt of such notice. The Landlord, the Mortgagee or the Purchaser, as the case may be, may require the Tenant to enter into all instruments required by the Landlord, the Mortgagee or the Purchaser, as the case may be, to confirm such attornment. Upon such attornment the obligations of the Tenant under this Lease shall continue in full force and effect upon all the same terms, conditions and covenants in this Lease.

13.3 Status Certificates

The Tenant shall at any time and from time to time execute and deliver to the Landlord, or as the Landlord, a Mortgagee or a Purchaser may direct, within •~~five~~• ten Business Days after it is requested, a certificate of the Tenant, in the form supplied, addressed to the Landlord, the Mortgagee or the Purchaser, as the case may be, and/or any prospective purchaser, lessor or Mortgagee, certifying such particulars, information and other matters in respect of the Tenant (including its financial standing), the Premises and this Lease that the Landlord, the Mortgagee or the Purchaser, as the case may be, may request. The Tenant will be liable for damages to the Landlord for failure to execute and deliver the requested certificate. Failure to execute the requested certificate within the stipulated •~~five~~• ten Business Day period is a default under this Lease and the Landlord may, at its option, terminate this Lease without incurring any liability for so doing.

13.4 Reliance

Notwithstanding that a Mortgagee or a Purchaser is not a party to this Lease, it shall be entitled to rely upon and enforce the provisions of this Lease which are stated to be for its benefit and, without limitation, the Mortgagee shall be entitled to act as agent for the Landlord to the extent necessary to enforce any such provisions.

ARTICLE 14 - DAMAGE, DESTRUCTION, DEMOLITION, EXPROPRIATION

14.1 Damage to Premises

If all or any material part of the Premises is rendered untenantable or completely inaccessible by damage from fire or other casualty to the Building or Project, then:

(a)	if in the opinion of the Expert, the damage can be substantially repaired under Applicable Laws within 180 days from the date of such casualty (employing normal construction methods without overtime or other premium), the Landlord shall forthwith repair such damage other than damage to Leasehold Improvements and any other property that is not the responsibility of or is not owned by Landlord; and

(b)	if in the opinion of the Expert, the damage cannot be substantially repaired under Applicable Laws within 180 days from the date of such casualty (employing normal construction methods without overtime or other premium), then:

	(i)	the Landlord may elect to terminate this Lease as of the date of such casualty by notice delivered to the Tenant not more than 20 days after receipt of the Expert's opinion; and

	(ii)	if such damage occurs during the last two Lease Years of the Term, the Tenant may elect to terminate this Lease as of the date of such casualty by notice delivered to Landlord not more than 20 days after receipt of the Expert's opinion,

failing which the Landlord shall forthwith repair such damage other than damage to Leasehold Improvements or property that is not the responsibility of or is not owned by Landlord.

14.2 Abatement

If the Landlord is required to repair damage to the Premises under Section 14.1 the Basic Rent payable by the Tenant shall be proportionately reduced to the extent that the Premises are rendered untenantable or inaccessible, from the date of the casualty until 30 days after completion by the Landlord of the repairs to the Premises or until the Tenant again uses the Premises (or the part thereof rendered untenantable), whichever first occurs. The Tenant shall effect its own repairs as soon as possible after completion of the Landlord's repairs. Notwithstanding the foregoing, there shall be no abatement or reduction of Rent where the Landlord's repairs to the Premises take less than ten days to complete after the damage occurs.

14.3 Termination Rights

Notwithstanding anything else contained in this Lease, if: (a) the Building is partially destroyed or damaged so as to affect 25% or more of the Rentable Area of the Building; or (b) in the opinion of the Expert the Building is unsafe or access or services are affected and, in either case, cannot be substantially repaired under Applicable Laws within 180 days from the date of such casualty (employing normal construction methods without overtime or other premium); or (c) the proceeds of insurance are substantially insufficient to pay for the costs of repair or rebuilding or are not payable to or received by the Landlord; or (d) any Mortgagee(s) or other Person entitled to the insurance proceeds shall not consent to the repair and rebuilding, then the Landlord may terminate this Lease by giving to the Tenant notice of such termination within 60 days of the damage or destruction, in which event the Term shall cease and be at an end as of the date of such damage or destruction and the Rent and all other payments for which the Tenant is liable under the terms of this Lease shall be apportioned and paid in full to the date of termination (subject to any abatement under Section 14.2) .

14.4 Landlord's Rights on Rebuilding

In the event of damage to the Building and if this Lease is not terminated in accordance with Sections 14.1 or 14.3, the Landlord shall forthwith repair any damage to the Building, but only to the extent of the Landlord's obligations under the terms of the various leases for premises in the Building (including this Lease) and exclusive of any tenant's responsibilities with respect to such repair. In repairing or rebuilding the Building or the Premises the Landlord may use drawings, designs, plans and specifications other than those used in the original construction and may alter or relocate the Building, the Common Areas and Facilities or any part thereof, and may alter or relocate the Premises, provided that the Building as repaired or rebuilt is of a similar standard and the Premises as altered or relocated shall be of approximately the same size as the original Premises.

14.5 Landlord's Demolition Rights

Despite any other provisions of this Lease, if the Landlord intends to demolish or renovate substantially the Building or a substantial portion of the Building, the Landlord may terminate this Lease on not less than 180 days’ notice to

the Tenant. The Tenant shall on the date set out in the notice from the Landlord vacate the Premises in accordance with the terms of this Lease. Also on such date, the Term shall cease and be at an end and the Rent and all other payments for which the Tenant is liable under the terms of this Lease shall be apportioned and paid in full to the date of termination.

14.6 Expropriation

The Landlord and the Tenant shall co-operate in respect of any expropriation of all or any part of the Premises or the Lands and Building so that each party may receive the maximum award to which it is entitled in law. If the whole or any part of the Premises or of the Lands and Building are expropriated, as between the parties hereto, their respective rights and obligations under this Lease shall continue until the day on which the expropriating authority takes possession thereof. If, in the case of partial expropriation of the Premises this Lease is not frustrated by operation of governing law and such expropriation does not render the remaining part of the Premises untenantable for the purposes of this Lease, the Tenant and the Landlord shall restore the part not so taken in accordance with their respective repair obligations under the provisions of Sections 14.1(a) and 14.2 of this Lease. In this Section 14.6 the word "expropriation" shall include a sale by the Landlord to any authority with powers of expropriation, in lieu of or under threat of expropriation.

ARTICLE 15 - DEFAULT AND REMEDIES

15.1 Events of Default

Any of the following constitutes an Event of Default under this Lease:

(a)	any Rent (which term for the purpose of this Article 15 shall include Rental Taxes) is in arrears and is not paid within five days after notice from the Landlord;

(b)	the Tenant has breached any of its obligations in this Lease and, if such breach is capable of being remedied and is not otherwise listed in this Section 15.1, after notice from the Landlord:

	(ii)	if such breach cannot reasonably be remedied within ten days or such shorter period, the Tenant fails to commence to remedy such breach within such ten days or shorter period or thereafter fails to proceed diligently to remedy such breach;

(c)	the Lease or any goods, chattels or equipment of the Tenant is seized, taken or exigible in execution or in attachment or if a writ of execution or enforcement is issued against the Tenant and such writ is not stayed or vacated within ten days after the date of such issue;

(d)	the Tenant or any Indemnifier becomes insolvent or commits an act of bankruptcy or takes the benefit of any statute for bankrupt or insolvent debtors or makes any proposal, assignment, compromise or arrangement with its creditors, or if a receiver is appointed for all or part of the business, property, affairs or revenues of the Tenant;

(e)	the Tenant makes a bulk sale of its goods (other than in conjunction with a Transfer approved by the Landlord) or moves or commences, attempts or threatens to move its goods, chattels and equipment out of the Premises (other than in the normal course of its business);

(f)	the Tenant fails to take possession of and occupy the Premises on the Commencement Date, or if thereafter the Tenant abandons or attempts to abandon the Premises or ceases to conduct business from the Premises, or the Premises become vacant or substantially unoccupied for a period of ten consecutive days; or

(g)	the Tenant purports to effect a Transfer other than in compliance with the provisions of this Lease.

15.2 Remedies

If and whenever an Event of Default occurs, the Landlord shall have the following rights and remedies, exercisable immediately and without further notice and at any time while the Event of Default continues:

(a)

to terminate this Lease and re-enter the Premises. The Landlord may remove all Persons and property from the Premises and store such property at the expense and risk of the Tenant or sell or dispose of such property in such manner as the Landlord sees fit without notice to the Tenant. Notwithstanding any termination of this Lease, the Landlord shall be entitled to receive Rent and all Rental Taxes up to the time of termination plus accelerated Rent as provided in this Lease and damages including, without limitation: (i) damages for the loss of Rent suffered by reason of this Lease having been prematurely terminated; (ii) costs of reclaiming, repairing and re-leasing the Premises; and (iii) legal fees and disbursements on a solicitor and client basis;

	(b)	to enter the Premises as agent of the Tenant and to relet the Premises for whatever length of time and on such terms as the Landlord in its discretion may determine including, without limitation the right to: (i) take possession of any property of the Tenant on the Premises; (ii) store such property at the expense and risk of the Tenant; (iii) sell or otherwise dispose of such property in such manner as the Landlord sees fit; and (iv) make alterations to the Premises to facilitate the reletting. The Landlord shall receive the rent and proceeds of sale as agent of the Tenant and shall apply the proceeds of any such sale or reletting first, to the payment of any expenses incurred by the Landlord with respect to any such reletting or sale, second, to the payment of any indebtedness of the Tenant to the Landlord other than Rent and third, to the payment of Rent in arrears, with the residue to be held by the Landlord and applied to payment of future Rent as it becomes due and payable. The Tenant shall remain liable for any deficiency to the Landlord;

	(c)	to remedy or attempt to remedy the Event of Default for the account of the Tenant and to enter upon the Premises for such purposes. The Landlord shall not be liable to the Tenant for any loss, injury or damages caused by acts of the Landlord in remedying or attempting to remedy the Event of Default. The Tenant shall pay to the Landlord, on demand, all expenses incurred by the Landlord in remedying the Event of Default, together with an administration fee of 15% and interest at the Default Rate from the date such expense was incurred by Landlord;

	(d)	to recover from the Tenant all damages, costs and expenses incurred by the Landlord as a result of the Event of Default including any deficiency between those amounts which would have been payable by the Tenant for the portion of the Term following such termination and the net amounts actually received by the Landlord during such period of time with respect to the Premises; and

	(e)	to recover from the Tenant the full amount of the current month's Rent together with the next three months' instalments of Rent, which shall immediately become due and payable as accelerated rent.

15.3 Distress

Notwithstanding any provision of this Lease or any provision of any present or future Applicable Laws, none of the goods, chattels or trade fixtures on the Premises at any time during the Term shall be exempt from levy by distress for Rent in arrears, and the Tenant waives any such exemption. If the Landlord makes any claim against the goods and chattels of the Tenant by way of distress this provision may be pleaded as an estoppel against the Tenant in any action brought to test the right of the Landlord to levy such distress.

15.4 Interest and Costs

The Tenant shall pay to the Landlord upon demand: (a) interest at the Default Rate on all Rent required to be paid hereunder from the due date for payment until fully paid and satisfied; and (b) the Landlord’s then current administration charge for each notice of default given by the Landlord to the Tenant under this Lease. The Tenant shall pay and indemnify the Landlord against damages, costs and expenses (including, without limitation, all legal fees on a solicitor and client basis) incurred in enforcing the terms of this Lease, or with respect to any matter or thing which is the obligation of the Tenant under this Lease, or in respect of which the Tenant has agreed to insure or to indemnify the Landlord.

15.5 Remedies Cumulative

No reference to or exercise of any specific right or remedy by the Landlord shall prejudice or preclude the Landlord from exercising or invoking any other remedy, whether allowed under this Lease or generally at law or in equity, and the express provisions of this Lease as to certain rights and remedies are not to be interpreted as excluding any other or additional rights and remedies available to the Landlord generally at law or in equity.

ARTICLE 16 – MISCELLANEOUS

16.1 Relationship of Parties

Nothing contained in this Lease shall create any relationship between the parties other than that of landlord and tenant, and, without limitation, nothing in this Lease shall be construed to constitute the Landlord and the Tenant as partners, joint venturers or members of a joint or common enterprise.

16.2 Consent Not to be Unreasonably Withheld

Except as otherwise specifically provided in this Lease, the Landlord and the Tenant, and each Person acting for them, in granting a consent or approval or making a determination, designation, calculation, estimate, conversion or allocation under this Lease, will act reasonably and in good faith and each Expert or other professional Person employed or retained by the Landlord will act in accordance with the applicable principles and standards of such Person's profession; however, the foregoing shall not apply in respect of any actions taken by or on behalf of the Landlord under Article 15. The Tenant's sole remedy against the Landlord in respect of any breach or alleged breach of this Section shall be an action for specific performance and, without limitation, the Landlord shall not be liable for damages and the Tenant shall not be entitled to any other rights or remedies.

16.3 Overholding

The Tenant has no right to remain in possession of the Premises after the end of the Term. If the Tenant remains in possession of the Premises after the end of the Term with the consent of the Landlord but without entering into a new lease or other agreement then, notwithstanding any statutory provisions, legal presumption or reasonableness requirement to the contrary, there shall be no tacit renewal of this Lease or the Term and the Tenant shall be deemed to be occupying the Premises as a tenant from month to month (with either party having the right to terminate such month to month tenancy at any time on 30 days' notice, whether or not the date of termination is at the end of a rental period) at a monthly Basic Rent payable in advance on the first day of each month equal to double the monthly amount of Basic Rent payable during the last month of the Term (or which would have been payable but for any discount or rent-free period applicable to such last month) and otherwise upon the same terms, covenants and conditions as in this Lease insofar as these are applicable to a monthly tenancy and, for greater certainty, including liability for all Additional Rent.

16.4 Registration

Neither the Tenant nor anyone on the Tenant's behalf or claiming under the Tenant (including any Transferee) shall register this Lease or any Transfer against the Lands. The Tenant may at its sole cost register a notice or caveat of this Lease provided that: (a) a copy of the Lease is not attached; (b) no financial terms are disclosed; (c) the Landlord gives its prior written approval to the notice or caveat; and (d) the Tenant pays the Landlord's costs on account of the matter. The Landlord may limit such registration to one or more parts of the Lands. Upon the expiration or other termination of the Term the Tenant shall immediately discharge or otherwise vacate any such notice or caveat at its sole cost. If any part of the Lands which in the opinion of the Landlord are surplus is transferred, the Tenant shall forthwith at the request of the Landlord discharge or otherwise vacate any such notice or caveat as it relates to such part. If any part of the Lands are made subject to any easement, right-of-way or similar right, the Tenant at its sole cost shall immediately at the request of the Landlord, which request the Landlord may make in its sole discretion, postpone its registered interest to such easement, right-of-way or similar right.

16.5 Unavoidable Delay

If any party is bona fide delayed, or hindered in or prevented from the performance of any term, covenant or act required by this Lease by reason of any cause beyond the control of the party affected including, without limitation, strikes, lockouts or other labour disputes, the enactment, amendment or repeal of any Applicable Laws, the failure of any existing tenant or occupant to vacate the Premises, shortages or unavailability of labour or materials, riots, insurrection, sabotage, rebellion, war, acts of terrorism, act of God, or any other similar reason ("Unavoidable Delay"), then performance of such term, covenant or act is excused for the period of the delay and the party so delayed, hindered or prevented shall be entitled to perform such term, covenant or act within the appropriate time period after the expiration of the period of such delay. However, the provisions of this Section do not operate to excuse the Tenant from the prompt payment of Rent and any other payments required by this Lease or from vacating the Premises as and when required pursuant to any provision of this Lease and Unavoidable Delay shall not include any delay caused by the parties' default or act or omission, any delay avoidable by the exercise of reasonable care by such party or any delay caused by lack of funds of such party. The Landlord shall also be excused from the performance of any term, covenant or act required hereunder if the performance of such item would be in conflict with any directive, policy or request of any governmental or quasi-governmental authority in respect of any energy, conservation, safety or security matter.

16.6 Decisions of Experts; Arbitration

The decision of any Expert whenever provided for under this Lease and any certificate of an Expert shall be final and binding on the parties and there shall be no further right of dispute or appeal.

Wherever under any provision of this Lease it is stated that a matter is to be determined by Arbitration, it shall be determined by a single arbitrator appointed by the parties. If the parties cannot agree on a single arbitrator, then, upon the application of either party, a Justice of the superior court of the province in which the Premises are situate shall appoint an arbitrator whose sole determination shall be final. The arbitrator shall be a disinterested person of recognized competence in the real estate business where the Premises are situate. The expense of such arbitration shall be borne equally by the Landlord and the Tenant.

16.7 Notices

Any notice, demand, statement or request ("Notice") required or permitted to be given under this Lease shall be in writing and shall be deemed to have been duly given if personally delivered, delivered by courier or mailed by registered prepaid post, in the case of Notice to the Landlord, to it at the address set out in Section 1.1(a)(ii) and in the case of Notice to the Tenant, to it at the Premises. Notice may not be given by facsimile transmission, electronic mail or any other electronic communication.

Any such Notice given in accordance with the above requirements shall be deemed to have been given, if mailed, on the fifth day following the date of such mailing or, if delivered, on the day on which it was delivered so long as such delivery was prior to 5:00 p.m. on a Business Day (and, if after 5:00 p.m. or if any such day is not a Business Day, then it shall be deemed to have been delivered on the next Business Day). Either party may from time to time by Notice change the address to which notices to it are to be given. Notwithstanding the foregoing, during any interruption or threatened interruption in postal services, any Notice shall be personally delivered or delivered by courier. If a copy of any Notice to the Tenant is to be sent to a second address or to another Person other than the Tenant, the failure to give any such copy shall not vitiate the delivery of the Notice to the Tenant.

16.8 Confidentiality

The Tenant shall keep confidential all financial information in respect of this Lease, provided that it may disclose such information to its auditors, consultants and professional advisors so long as they have first agreed to respect such confidentiality.

16.9 Power, Capacity and Authority

The Landlord and the Tenant covenant, represent and warrant to each other that they have the power, capacity and authority to enter into this Lease and to perform its obligations hereunder and that there are no covenants, restrictions or commitments given by it which would prevent or inhibit it from entering into this Lease.

16.10 Liability of Landlord

Any liability of the Landlord under this Lease shall be limited to its interest in the Building from time to time. If the Landlord consists of more than one Person, the liability of each such Person shall be several and be limited to its percentage interest in the Building.

~~(the "Indemnifier")~~

~~-and-~~

* [name of Landlord],

~~(the "Landlord").~~

~~WHEREAS:~~

~~A. The Landlord is the owner of the lands and premises known municipally as * [address of Building] (the "Building"); and~~

1. The Indemnifier covenants with the Landlord that the Tenant will well and truly pay all Rent and other amounts payable under the Lease on the days and at the times and in the manner provided in the Lease, and will observe each and every covenant, proviso, condition, agreement and obligation contained in the Lease on the part of the Tenant to be performed and observed, and that if any default is made by the Tenant, whether in payment of monies or performance of obligations, the Indemnifier shall forthwith on demand pay to the Landlord such monies and perform such obligations and pay any and all damages resulting from any non-payment or non-performance.

This Indemnity is absolute and unconditional and the obligations of the Indemnifier and the rights of the Landlord hereunder shall not be affected or in any way prejudiced or impaired by: (a) any neglect or forbearance by the Landlord in obtaining payment of Rent or other amounts or of enforcing the provisions of the Lease or the obligations of the Tenant or any waiver or failure to enforce any provision of this Agreement by the Landlord; (b) any extensions of time or other indulgences given by the Landlord to the Tenant; (c) any amendment of the Lease or other dealing between the Landlord and the Tenant with or without notice to the Indemnifier; (d) any assigning or subletting by the Tenant (with or without the Landlord's consent); or (e) any other act or failure to act by the Landlord which would release, discharge or affect the obligations of the Indemnifier if it were a mere surety, with the intent that the obligations of the Indemnifier shall continue and shall not be released, discharged or reduced or in any way impaired until such time as all of the obligations of the Tenant under the Lease, now existing or to arise at any time in the future, have been fully performed and satisfied.

4. The Indemnifier expressly waives notice of the acceptance of this Agreement and all notice of non-performance, non-payment or non-observance on the part of the Tenant of the terms, covenants and conditions in the Lease. Without limiting the generality of the foregoing, any notice which the Landlord desires to give to the Indemnifier shall be sufficiently given if personally delivered, delivered by courier or mailed by registered prepaid post, to the Indemnifier at the Premises, and every such notice is deemed to have been given upon the day it was delivered, or if mailed, on the fifth day following the date of such mailing. The Indemnifier may designate by notice in writing a substitute address for that set forth above. If two or more persons are named as Indemnifier, such notice given hereunder or under the Lease shall be sufficiently given if delivered or mailed in the foregoing manner to any one of such Persons.

5. The obligations of the Indemnifier under this Agreement shall not be released, discharged or affected by the bankruptcy or insolvency of the Tenant or any proposal made by it to its creditors or any repudiation of the Lease pursuant to the Bankruptcy and Insolvency Act, S.C. 1992, or any successor or similar legislation, or any disclaimer by any trustee in bankruptcy of the Tenant or by the Tenant ceasing to exist (whether by winding-up, forfeiture, cancellation or surrender of charter, or any other circumstance) or by any event terminating the Lease including a reentry or termination. If the Lease is terminated prior to the end of its term, except by surrender duly accepted by the Landlord, then, at the option of the Landlord, the Indemnifier shall execute a new lease of the Premises between the Landlord as landlord and the Indemnifier as tenant for a term equal in duration to the residue of the term remaining

~~unexpired at the date of such termination, and in all other respects upon the same terms and conditions as are set forth in the Lease.~~

6. The Landlord shall not be obliged to exercise its remedies against the Tenant or any other person or against the Premises or to exhaust any security given by the Tenant before demanding payment of monies or performance of covenants by the Indemnifier.

7. The Indemnifier's obligations under this Agreement bind the Indemnifier and its legal representatives, heirs, executors, administrators, successors and assigns (as the case may be) and may be assigned by the Landlord, and will benefit and be enforceable by the successors and assigns of the Landlord, and all parties who for the time being have the status of Landlord under the Lease, whether or not such parties receive a specific assignment of the Lease or of the Indemnifier's obligations, and whether or not notice of any assignment or change in ownership of the Premises or any project of which the Premises forms a part is given to the Indemnifier.

8. The grammatical changes required to make the provisions of this Agreement apply in the plural sense where the Indemnifier comprises more than one person and to corporations, firms, partnerships, or individuals male or female, will be assumed as though in each case fully expressed, and if the Indemnifier consists of more than one person, the obligations of the Indemnifier shall be deemed to be joint and several obligations of each such person. This Agreement shall be construed in accordance with the laws of the province in which the Building is located. The exclusive venue for any application or court action brought in respect of this Agreement shall lie with the courts of the Province in which the Premises is located, and the parties hereto exclusively attorn to the jurisdiction of such courts.

9. The Indemnifier acknowledges receipt of a copy of the Lease and covenants, represents and warrants that it has full power, capacity and authority to enter into this Agreement and to perform its obligations hereunder. No modification of this Agreement shall be effective unless it is in writing and is executed by both the Indemnifier and the Landlord.

10. Whenever any reference is made in this Agreement to the Lease or the obligations of the Tenant under the Lease, such reference shall be deemed to include any and all agreements and instruments executed by the Tenant in connection with the Lease or pursuant to the Lease and which relate to the Premises. Any capitalized word or phrase used in and not defined in this Agreement shall have the meaning given to it in the Lease.

SCHEDULE "E" CONDITION OF PREMISES

CONSTRUCTION AND COMPLETION OF THE PREMISES

The Tenant acknowledges and agrees that it is accepting possession of the Premises in an "as is, where is" condition except that the Landlord shall provide and install to the Premises at the Landlord's expense and to its base building standard, the following work (the “Landlord’s Work”):

(a)	repaint the Premises in a colour to be chosen by the Tenant;

(b)	replace carpets and kitchen linoleum with building standard carpeting, colours to be chosen by the Tenant from samples provided by the Landlord; and

(c)	repair or replace all damaged or stained ceiling tiles to like new condition.

The Landlord makes no representation or warranty with respect to the usability of any existing phone lines and/or data cables within the Premises. The Tenant, at its expense, shall be responsible for all modifications required to reuse such phone lines and/or data cables. The Tenant shall be responsible for its own improvements to the Premises (the "Tenant's Work") and shall complete such Tenant's Work during the Fixturing Period. Should the Tenant require additional utilities, additional heating, ventilation or air conditioning because of the nature of its business, in excess of those already provided to the Premises, then the Tenant shall be responsible for the cost of installing and/or supplying such additional utilities, subject to the Landlord’s prior approval. The Tenant’s Work is subject to the Landlord’s prior written approval and shall be made in accordance with Section 9.2 of the Lease and the Sun Life Plaza Tenant Guidelines. It is understood that the Landlord’s contractor shall be utilized for all changes to the mechanical, electrical and life safety systems. All costs associated with the Tenant’s Work shall be borne solely by the Tenant, including design and consultants’ fees. The Tenant will be responsible for obtaining all necessary approvals and building permits from regulatory authorities for the commencement and completion of the Tenant’s Work. No Tenant’s Work shall commence until the Landlord receives proof of the Tenant's insurance. All terms of the Lease shall be applicable from the date the Tenant takes possession of the Premises including the Tenant's obligations to pay for all utilities and services, save for the payment of Basic Rent and the Tenant's share of Property Taxes and Operating Costs which shall be payable as of the Commencement Date.
