4.2 Leasing Activity

	(a)		The Purchaser agrees that in the period following the date of execution of this Agreement by both parties and up to the date for satisfaction or waiver of the conditions referred to in Section 9.1(b), the Vendors may carry on their leasing program for the Lot F Property and the Building.

	(b)		If the transactions contemplated by this Agreement are completed, the Purchaser will assume all such commitments from and after the Closing Date and will fully perform the obligations of the Vendors pursuant to such commitments, including honouring obligations to provide any tenant inducements to the Tenants or prospective tenants of the Lot F Property and the Building, and being responsible for all commissions that are payable and all landlord’s work thereunder and the same will not be subject to adjustment on closing, except that, if the term of any new lease commences prior to the Closing Date, then the responsibility for any related tenant inducements (including landlord’s work) and commissions will be pro-rated between the Vendors and the Purchaser on the basis of the number of months of the initial term of such lease prior to the Closing Date (as for the

-12-

			Vendors) and the number of months of the initial term of such lease after the Closing Date (as for the Purchaser), and the same will be subject to adjustment on closing.

	(c)		The Vendors agree that after the conditions referred to in Section 9.1(b) are satisfied or waived by the Purchaser, the Vendors will not enter into any binding commitments with Tenants or prospective tenants for the Lot F Property or the Building or any material modification of any Lease without the Purchaser’s prior written approval, which approval may be withheld in the Purchaser’s sole and absolute discretion.

	(d)		The Vendors agree that if they carry on the leasing program, they will do so in good faith in the ordinary course following the date of execution of this Agreement by both parties and will only consider commitments with tenants and prospective tenants which are consistent with market driven leasing arrangements in the Vancouver market.

4.3 Estoppel Certificates

The Vendors shall use all reasonable commercial efforts to obtain and deliver to the Purchaser prior to the completion of the purchase and sale of the Purchased Assets, Estoppel Certificates executed by all Tenants.

The Replacement Estoppel Certificates will be deemed for all purposes to be a representation and warranty hereunder by the Vendors of the truth and accuracy of the matters set forth in the Replacement Estoppel Certificates, subject to the limitations set forth in Section 11.2. The Purchaser shall, for a period of sixty (60) days after the Closing Date, return to the Vendors any Replacement Estoppel Certificate (which shall be deemed null and void except in the case of a material conflict of information contained in the Estoppel Certificate and the Replacement Estoppel Certificate) for which the Vendors delivers to the Purchaser an Estoppel Certificate in accordance with this Section 4.3 for the same Lease.

-13-

own behalf and, unless otherwise required by applicable law, on behalf of the Vendors, and pay all fees in connection therewith, that are required pursuant to the Competition Act in respect of the purchase of the Purchased Assets and the other transactions contemplated by this Agreement. The Vendors shall co-operate with the Purchaser and provide the Purchaser with information that is in the possession of the Vendors and is necessary to give such notification and to make such filing.

The Properties shall be at the risk of the Vendors until the completion of the sale and purchase contemplated by this Agreement and, if there is any material damage to the Building or the Mechanical Systems occurring before that time, the Purchaser shall elect, no later than seven (7) days after receiving written notice from the Vendors of the occurrence of such event (and in any event prior to the Closing Date) by notice in writing, either:

	(a)		to terminate this Agreement, in which case the Deposit together with accrued interest will be paid to the Purchaser in accordance with Section 2.3(b) and neither the Vendors nor the Purchaser shall have any further obligation hereunder; or

	(b)		to complete the transactions contemplated by this Agreement.

The Vendors shall give to the Purchaser prompt written notice of the occurrence of any material damage to the Building or the Mechanical Systems. Failure by the Purchaser to so elect within the time provided above shall be deemed to be an election to complete the transactions contemplated by this Agreement. For the purpose of this Section, material damage means loss or damage to or destruction of the Building or the Mechanical Systems to such an extent in either event that a quantity surveyor engaged by the Vendors certifies that the replacement or repair thereof cannot be completed for a cost of less than $2,000,000.00.

5.2 Insurance Proceeds

The amount of any insurance proceeds in connection with loss or damage occurring prior to the passing of risk and not applied by the Vendors or the insurer to the cost of repairs, shall, if the Purchaser elects or is deemed to have elected to complete, be assigned to and be payable to the Purchaser.

ARTICLE 6
ADJUSTMENTS AND RELATED MATTERS

6.1 Adjustments

Adjustments will be made in accordance with the following provisions:

	(a)		except as otherwise provided herein, all adjustments, both incoming and outgoing, with respect to the Properties, including taxes, utilities, rents, common area and operating expenses, deposits and interest thereon, tenant allowances, tenant recharges, fuel, licences, insurance, audit costs, payments under Approved Service Contracts and other items normally adjusted between a vendor and purchaser in the sale of similar properties shall be adjusted as of the Closing Date so that the Vendors will bear and pay all expenses and receive all income related to the Properties prior to the Closing Date and the Purchaser will bear and pay all expenses and receive all income related to the Properties from and including the Closing Date;

	(b)		the Vendors will remain liable to remit, in accordance with Part IX of the Excise Tax Act (Canada), any goods and services tax exigible on taxable supplies made by the Vendors and that became payable (as contemplated in Section 168 of the Excise Tax Act (Canada)) prior to the Closing Date;

	(c)		the Vendors shall not be credited with arrears of rent or other charges owed by Tenants as of the Closing Date, except that the Vendors shall be credited for arrears of rent and any other charges owed by any Tenant as of the Closing Date in respect of the then current month so long as such Tenant is not then in arrears for any previous month; the Purchaser and the Vendors each agree to cooperate with the other in respect of the collection of any then current arrears (including the full amount of any unpaid federal goods and services tax payable by the Tenants on such arrears). The Vendors shall provide the Purchaser with detailed information as to the determination of the amount of such arrears, and the Purchaser shall take reasonable steps in order to collect such arrears as soon as may be practicable. If and when the Purchaser collects any such arrears the Purchaser will remit to the Vendors that portion due to the Vendors in respect of the period prior to the dates of adjustment for the respective components of such arrears, less any reasonable third party collection costs. For greater certainty, the Vendors will be entitled to receive the full amount of goods and services tax paid on arrears by the Tenants if such goods and services tax became payable (as contemplated in Section 168 of the Excise Tax Act (Canada)) prior to the Closing

-15-

			Date. Payment of rents and recoveries shall be applied first to current rents and recoveries and the excess to the latest arrears. The Vendors shall be entitled to attempt to collect any such arrears the Purchaser has not collected within three (3) months after the Closing Date, provided that it shall not be entitled to terminate any Tenant’s lease or seize any of the Tenant’s property on the Tenant’s premises;

	(d)		although the Purchaser will be entitled, subject to the Vendors’ right under Section 6.1(c), to collect all rentals and other recoveries after the Closing Date whether applicable to periods prior to or after the Closing Date, the Purchaser and the Vendors agree to receive in trust and promptly remit to the other that portion of any rentals or recoveries received by it as would reasonably be expected to be credited to or by the other party hereunder on a subsequent adjustment, subject to the provisions of Section 6.1(c). Any rents and recharges received by the Vendors and designated by a Tenant or other occupant to be applied to a period ending after the date of adjustment for the subject matter of such arrears will be promptly paid or endorsed over to the Purchaser; and

	(e)		if any dispute arises with regard to the adjustments referred to in Article 6 either before or after the Closing Date, the matter in dispute will be referred in the first instance to the auditors of the Purchaser and the auditors of the Vendors for determination. If such auditors cannot agree on a determination of the matter in dispute within thirty (30) days following the reference to them, the matter in dispute will be referred to a single arbitrator under the Commercial Arbitration Act (British Columbia) or any successor legislation then in effect in British Columbia. The Vendors and Purchaser will make any references mentioned herein expeditiously and will share all arbitration costs equally.

6.2 Further Adjustments

A further adjustment with respect to the matters set forth in Section 6.1 which could not be finally adjusted on the Closing Date will be made no later than six (6) months after the Closing Date.

6.3 Adjustment Determination

Both before and after the Closing Date, the Vendors and the Purchaser will use their best efforts to determine all adjustments.

6.4 Tenant Inducements and Rent-Free Periods

Any existing free-rent periods or other existing tenant inducements or leasing commissions occurring after the Closing Date (but excluding any of the same that arise out of commitments entered into by the Vendors pursuant to Section 4.2 except as provided therein) shall be set out in the tenancy schedule delivered to the Purchaser as part of the Project Documents and determined on the Closing Date and the applicable amounts so determined shall be present valued at a discount rate of six percent (6%) per annum and the discounted amount shall be the responsibility of the Vendors and paid by way of adjustment in favour of the Purchaser on the Closing Date. The Purchaser shall indemnify and save harmless the Vendors

-16-

from and against any and all claims, charges, costs, expenses and liabilities that the Vendors or any of them may at any time suffer or incur as a result of any failure by the Purchaser to pay or perform any such free-rent periods, tenant inducements or leasing commitments so adjusted.

The Properties shall be at the risk of the Vendors until the completion of the sale and purchase contemplated by this Agreement and, if there is any material damage to the Building or the Mechanical Systems occurring before that time, the Purchaser shall elect, no later than seven (7) days after receiving written notice from QLT of the occurrence of such event (and in any event prior to the Closing Date) by notice in writing, either:

(b)

to complete the transactions contemplated by this Agreement.

QLT shall give to the Purchaser prompt written notice of the occurrence of any material damage to the Building or the Mechanical Systems.

6.1 Adjustments

Adjustments will be made in accordance with the following provisions:

	(a)		except as otherwise provided herein, all adjustments, both incoming and outgoing, with respect to the Properties, including taxes, utilities, rents, common area and operating expenses, deposits and interest thereon, tenant allowances, tenant recharges, fuel, licences, insurance, audit costs, payments under Approved Service Contracts and other items normally adjusted between a vendor and purchaser in the sale of similar properties shall be adjusted as of the Closing Date so that QLT will bear and pay all expenses and receive all income related to the Properties prior to the Closing Date and the Purchaser will bear and pay all expenses and receive all income related to the Properties from and including the Closing Date;

	(b)		QLT will remain liable to remit, in accordance with Part IX of the Excise Tax Act (Canada), any goods and services tax exigible on taxable supplies made by QLT and that became payable (as contemplated in Section 168 of the Excise Tax Act (Canada)) prior to the Closing Date;

	(c)		QLT shall not be credited with arrears of rent or other charges owed by Tenants as of the Closing Date, except that QLT shall be credited for arrears of rent and any other charges owed by any Tenant as of the Closing Date in respect of the then current month so long as such Tenant is not then in arrears for any previous month; the Purchaser and QLT each agree to cooperate with the other in respect of the collection of any then current arrears (including the full amount of any unpaid federal goods and services tax payable by the Tenants on such arrears).

-15-

			QLT shall provide the Purchaser with detailed information as to the determination of the amount of such arrears, and the Purchaser shall take reasonable steps in order to collect such arrears as soon as may be practicable. If and when the Purchaser collects any such arrears the Purchaser will remit to QLT that portion due to QLT in respect of the period prior to the dates of adjustment for the respective components of such arrears, less any reasonable third party collection costs. For greater certainty, QLT will be entitled to receive the full amount of goods and services tax paid on arrears by the Tenants if such goods and services tax became payable (as contemplated in Section 168 of the Excise Tax Act (Canada)) prior to the Closing Date. Payment of rents and recoveries shall be applied first to current rents and recoveries and the excess to the latest arrears. QLT shall be entitled to attempt to collect any such arrears the Purchaser has not collected within three (3) months after the Closing Date, provided that it shall not be entitled to terminate any Tenant’s lease or seize any of the Tenant’s property on the Tenant’s premises;

	(d)		although the Purchaser will be entitled, subject to QLT’s right under Section 6.1(c), to collect all rentals and other recoveries after the Closing Date whether applicable to periods prior to or after the Closing Date, the Purchaser and QLT agree to receive in trust and promptly remit to the other that portion of any rentals or recoveries received by it as would reasonably be expected to be credited to or by the other party hereunder on a subsequent adjustment, subject to the provisions of Section 6.1(c). Any rents and recharges received by QLT and designated by a Tenant or other occupant to be applied to a period ending after the date of adjustment for the subject matter of such arrears will be promptly paid or endorsed over to the Purchaser; and

	(e)		if any dispute arises with regard to the adjustments referred to in Article 6 either before or after the Closing Date, the matter in dispute will be referred in the first instance to the auditors of the Purchaser and the auditors of QLT for determination. If such auditors cannot agree on a determination of the matter in dispute within thirty (30) days following the reference to them, the matter in dispute will be referred to a single arbitrator under the Commercial Arbitration Act (British Columbia) or any successor legislation then in effect in British Columbia. QLT and Purchaser will make any references mentioned herein expeditiously and will share all arbitration costs equally.

6.2 Further Adjustments

A further adjustment with respect to the matters set forth in Section 6.1 which could not be finally adjusted on the Closing Date will be made no later than six (6) months after the Closing Date.

-16-

6.3 Adjustment Determination

Both before and after the Closing Date, QLT and the Purchaser will use their best efforts to determine all adjustments.

6.4 Tenant Inducements and Rent-Free Periods

Any existing free-rent periods or other existing tenant inducements or leasing commissions occurring after the Closing Date (but excluding any of the same that arise out of commitments entered into by the Vendors pursuant to Section 4.2 except as provided therein) shall be set out in the tenancy schedule delivered to the Purchaser as part of the Project Documents and determined on the Closing Date and the applicable amounts so determined shall be present valued at a discount rate of six percent (6%) per annum and the discounted amount shall be the responsibility of QLT and paid by way of adjustment in favour of the Purchaser on the Closing Date. The Purchaser shall indemnify and save harmless QLT from and against any and all claims, charges, costs, expenses and liabilities that QLT may at any time suffer or incur as a result of any failure by the Purchaser to pay or perform any such free-rent periods, tenant inducements or leasing commitments so adjusted.

ADJUSTMENTS AND RELATED MATTERS

6.1 Adjustments

Adjustments will be made in accordance with the following provisions:

	(a)		except as otherwise provided herein, all adjustments, both incoming and outgoing, with respect to the Properties, including taxes, utilities, rents, common area and operating expenses, deposits and interest thereon, tenant allowances, tenant recharges, fuel, licences, insurance, audit costs, payments under Approved Service Contracts and other items normally adjusted between a vendor and purchaser in the sale of similar properties shall be adjusted as of the Closing Date so that QLT will bear and pay all expenses and receive all income related to the Properties prior to the Closing Date and the Purchaser will bear and pay all expenses and receive all income related to the Properties from and including the Closing Date;

	(b)		QLT will remain liable to remit, in accordance with Part IX of the Excise Tax Act (Canada), any goods and services tax exigible on taxable supplies made by QLT and that became payable (as contemplated in Section 168 of the Excise Tax Act (Canada)) prior to the Closing Date;

	(c)		QLT shall not be credited with arrears of rent or other charges owed by Tenants as of the Closing Date, except that QLT shall be credited for arrears of rent and any other charges owed by any Tenant as of the Closing Date in respect of the then current month so long as such Tenant is not then in arrears for any previous month;

-15-

			the Purchaser and QLT each agree to cooperate with the other in respect of the collection of any then current arrears (including the full amount of any unpaid federal goods and services tax payable by the Tenants on such arrears). QLT shall provide the Purchaser with detailed information as to the determination of the amount of such arrears, and the Purchaser shall take reasonable steps in order to collect such arrears as soon as may be practicable. If and when the Purchaser collects any such arrears the Purchaser will remit to QLT that portion due to QLT in respect of the period prior to the dates of adjustment for the respective components of such arrears, less any reasonable third party collection costs. For greater certainty, QLT will be entitled to receive the full amount of goods and services tax paid on arrears by the Tenants if such goods and services tax became payable (as contemplated in Section 168 of the Excise Tax Act (Canada)) prior to the Closing Date. Payment of rents and recoveries shall be applied first to current rents and recoveries and the excess to the latest arrears. QLT shall be entitled to attempt to collect any such arrears the Purchaser has not collected within three (3) months after the Closing Date, provided that it shall not be entitled to terminate any Tenant’s lease or seize any of the Tenant’s property on the Tenant’s premises;

	(d)		although the Purchaser will be entitled, subject to QLT’s right under Section 6.1(c), to collect all rentals and other recoveries after the Closing Date whether applicable to periods prior to or after the Closing Date, the Purchaser and QLT agree to receive in trust and promptly remit to the other that portion of any rentals or recoveries received by it as would reasonably be expected to be credited to or by the other party hereunder on a subsequent adjustment, subject to the provisions of Section 6.1(c). Any rents and recharges received by QLT and designated by a Tenant or other occupant to be applied to a period ending after the date of adjustment for the subject matter of such arrears will be promptly paid or endorsed over to the Purchaser; and

	(e)		if any dispute arises with regard to the adjustments referred to in Article 6 either before or after the Closing Date, the matter in dispute will be referred in the first instance to the auditors of the Purchaser and the auditors of QLT for determination. If such auditors cannot agree on a determination of the matter in dispute within thirty (30) days following the reference to them, the matter in dispute will be referred to a single arbitrator under the Commercial Arbitration Act (British Columbia) or any successor legislation then in effect in British Columbia. QLT and Purchaser will make any references mentioned herein expeditiously and will share all arbitration costs equally.

6.2 Further Adjustments

A further adjustment with respect to the matters set forth in Section 6.1 which could not be finally adjusted on the Closing Date will be made no later than six (6) months after the Closing Date.

6.3 Adjustment Determination

Both before and after the Closing Date, QLT and the Purchaser will use their best efforts to determine all adjustments.

Tenant Inducements and Rent-Free Periods

Any existing free-rent periods or other existing tenant inducements or leasing commissions occurring after the Closing Date (but excluding any of the same that arise out of commitments entered into by the Vendors pursuant to Section 4.2 except as provided therein) shall be set out in the tenancy schedule delivered to the Purchaser as part of the Project Documents and determined on the Closing Date and the applicable amounts so determined shall be present valued at a discount rate of six percent (6%) per annum and the discounted amount shall be the responsibility of QLT and paid by way of adjustment in favour of the Purchaser on the Closing Date. The Purchaser shall indemnify and save harmless QLT from and against any and all claims, charges, costs, expenses and liabilities that QLT may at any time suffer or incur as a result of any failure by the Purchaser to pay or perform any such free-rent periods, tenant inducements or leasing commitments so adjusted.
