1.10 Use of the Premises -

The Tenant shall:

(a) Subject to the right of the Tenant to assign this lease or sublet a portion of premises as herein provided, not use or occupy or suffer or permit the Leased Premises or any part thereof, to be used or occupied for any purpose other than for research, development and pilot scale production of human pharmaceuticals or

The consent by the Landlord to an assignment or subletting will not constitute a waiver of its consent to a subsequent assignment or subletting, or a waiver of the obligation of the Guarantor as set forth in paragraph 1.11(b) herein. Any such assignment, transfer or subleasing, or otherwise shall be subject to all the terms and conditions of this lease, and the Tenant will remain jointly and severally liable with any such transferee, whether such joint and several responsibility be mentioned or not in any consent to such transfer, assignment or sub-leasing. An assignment or sub-letting of this lease or the Leased Premises if consented to by the Landlord will be prepared by the Landlord’s solicitors together with such additional documents as reasonably required by the said solicitors and all reasonable legal costs of its preparation will be paid by the Tenant. If the Tenant or any sub-tenant or assignee of this Lease is a corporation, then any sale or other disposition resulting in a substantial sale of its assets or change in the shareholders controlling such corporation at any time during the Term or any renewal thereof shall be and be deemed to be an assignment of this Lease and, accordingly, the prior written consent of the Landlord to any such sale or disposition shall be required. A change in control of shareholdings of the Tenant as between the existing shareholders upon execution of the Lease, shall not be deemed an assignment of the lease as aforesaid.

(b) Guarantee - In the event that the Tenant assigns this Lease or sublets all or part of the Leased Premises during the initial term with the consent of the Landlord, in consideration of the premises and other valuable consideration, the receipt whereof and the sufficiency whereof is hereby acknowledged by the Tenant, the Tenant as Guarantor does hereby unconditionally guarantee all obligations of the then Tenant under this Lease and accordingly covenants with the Tenant that all the covenants, agreements and other obligations of the then

Tenant herein shall be fully performed, the guarantee being upon the following terms:

(i) The liability of the Guarantor to the Landlord is for all purposes as if the Guarantor was primary obligor herein, and not only sureties for the obligations of the then Tenant, and the Landlord is not obliged to resort to or exhaust any recourse which it has against the then Tenant or any other person before being entitled to claim against the Guarantor;

(ii) Any account settled or stated or any other settlement made between the Tenant and the Landlord, and any determination made pursuant to the provisions of this Lease which is expressed to be binding upon the then Tenant is binding upon the Guarantor;

(iii) The Guarantor shall make payment to the Landlord of any amount properly payable by the then Tenant to the Landlord but unpaid upon demand, and shall upon demand perform any other obligations under this Lease which the then Tenant has failed to perform, and any demand made by the Landlord upon the Guarantor is deemed to have been effectually made if notice thereof is sent as provided in paragraph 4.07;

(iv) No assignment of the Lease, sublease or any other dealings therewith by the then Tenant, whether with or without the consent of the Landlord, affects the guarantee;

(v) Nothing except the performance in full of all the obligations of the then Tenant under this Lease throughout the Term shall, except as provided in paragraph 1.11(c), discharge the Guarantor of this guarantee;

(vi) If during the Term the then Tenant makes an assignment for the general benefit of its creditors, or an order is made for the winding up of the then Tenant, or a receiving order in bankruptcy is made by or against the Landlord, and the assignee, liquidator or trustee surrenders possession of the Premises or any part of them or disclaims the lease, the Guarantor shall forthwith upon the demand of the Landlord at the Guarantor’s expense, accept from the Tenant a lease of the Premises (the “New Lease”) for a period equal in duration to the residue of the term remaining unexpired from the date of surrender or disclaimer at the same Minimum Rent and Additional Rent and with the same covenants and provisos as are reserved and contained in the Lease.

(c) This guarantee and all the liabilities and obligations of the Guarantor hereunder shall forthwith cease and terminate upon the completion of the Initial or Renewal Term.

4.00 PROVISOES

Provided always, and it is hereby agreed between the parties as follows:

4.01 Destruction or Damage of Leased Premises - If and whenever during the Term of this Lease the Leased Premises shall be destroyed or damaged by fire, lightning or tempest or any other perils, then and in every such event:

(a) if the damage or destruction is such that the Leased Premises are rendered wholly unfit for occupancy, or it is impossible or unsafe to use and occupy them, and if in either event the damage cannot be repaired with reasonable diligence within 120 days from the happening of such damage, then either party may within thirty (30) days of the happening of such damage or destruction terminate this Lease by giving to the other notice in writing of such termination in which event this Lease shall cease and be at an end as of the date of such damage 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 such damage. If neither the Landlord nor the Tenant so terminates this Lease, then the Landlord shall repair the building with all reasonable speed and the rent hereby reserved shall xxxxx from the date of the happening of the damage until the damage shall be made good and the Tenant can again use and occupy the Leased Premises;

(b) if the damage be such as the Leased Premises are wholly unfit for occupancy, or if it is impossible or unsafe to use or occupy them, but in either event the damage can be repaired with reasonable diligence within 90 days from the happening of such damage, then the rent hereby reserved shall xxxxx from the date of the happening of such damage until the damage shall be made good and the Tenant can again use and occupy the Leased Premises and the Landlord shall repair the damage with all reasonable speed;

(c) if the damage can be made good as aforesaid within 90 days of the happening of such damage and the damage is such that the Leased Premises are capable of being partially used for the purposes for which they are hereby demised, then until such damage has been repaired the rent shall be reduced by the fraction that the part of the Leased Premises which is rendered unfit for occupancy is of the whole of the Leased Premises and the Landlord shall repair the damage with all reasonable speed.

(d) In the event that the Landlord and Tenant shall be unable to agree as to the state of fitness of the Leased Premises and its condition, the question in dispute shall be referred to arbitration in accordance with Section 4.23 hereof but the certificate of an Architect selected by the Landlord, duly qualified to practice as such in the Province of Manitoba, shall bind the parties as to the length of time reasonably required to make any necessary repairs.

4.02 Expropriation - If the whole or any part of the Lease Premises shall be taken by any public authority under the power of eminent domain, the Term hereby granted shall cease from the day possession shall be taken for such public purposes insofar as the premises so taken comprise part of the Leased Premises; and the Tenant shall be liable only for rent in respect of the Leased Premises or part thereof so taken to the day of the taking, and if less than the whole be so taken, the Landlord or Tenant may at its option cancel and terminate this agreement with respect to the remainder of the Leased Premises, but notice of such cancellation must be given to the other within thirty (30) days after notice of such taking has been received by the Landlord; but if the Landlord or Tenant shall not elect to cancel the said Lease, the Tenant shall remain in possession of the remainder of the Leased Premises and the rent thereof shall be reduced in proportion that the space remaining possessed of the Landlord bears to the total ground floor space of the Leased Premises at the date of the commencement of this Lease. All compensation or damages awarded in respect of such taking of the Leased Premises and any diminution in value of the remainder thereof shall be the property of the Landlord but the Tenant shall be entitled to receive such compensation or damages as it may be able to establish against such public authority in respect to loss of its business, depreciation of and cost of removal of stock and fixtures.

4.03 Holding Over - If the Tenant shall remain in possession of the Leased Premises after termination of the Term hereby granted, or any renewal thereof as herein provided, without other special agreement, a tenancy from year to year shall not be created by implication of law, but the Tenant shall be deemed to be a monthly tenant only at a rent payable monthly in advance at a rate of One Hundred and Fifty (150%) percent of the

annual rent payable immediately prior to such termination, and otherwise upon and to the same terms and conditions as are herein contained, except provisions for renewal, and nothing, including acceptance of any rent by the Landlord, operates to extend any tenancy except a specific agreement in writing between the Landlord and Tenant.

4.04 Re-entry - If the Tenant shall default in making payment of the rents hereby reserved or any part thereof, when due and fails to pay same within five (5) days after notice to do so is provided by the Landlord or if the Tenant shall default in performance of observance of any of its other covenants herein contained, the Landlord, after ten (10) days written notice to the Tenant of such default and any default not being cured within the said period or such longer period as may reasonably be required in the circumstances (such period to be agreed upon in writing by the Landlord within the 10 days), may at its option at any time thereafter re-enter upon the Leased Premises or any part thereof in the name of the whole, and thereupon this Lease shall absolutely determine but without prejudice to the right of action of the Landlord in respect of any breach of the Tenant’s covenants herein contained.

4.05 Waiver - No condoning, excusing or overlooking by the Landlord of any default, breach or non-observance by the Tenant at any time or times in respect of any covenant, proviso or condition herein contained shall operate as a waiver of the Landlord’s rights hereunder in respect of any covenant, proviso or condition hereunder in respect of any continuing or subsequent default, breach or non-observance, or so as to defeat or affect in any way the right of the Landlord herein in respect of any such continuing or subsequent default or breach, and no waiver shall be inferred from or implied by anything done or omitted by the Landlord save only express waiver in writing. All rights and remedies of the Landlord in this Lease contained shall be cumulative and not alternative.

4.06 Remedies of Landlord as in the Case of Default of Rent - The Landlord shall have (in addition to any other right or remedy of the Landlord) the same rights and remedies in the event of default by the Tenant in payment of any amount payable by the Tenant hereunder, as the Landlord would have in the case of default in payment of rent.

4.07 Notice - Any notice required or contemplated by this Lease shall be sufficiently given if mailed by prepaid registered mail addressed to the proper party as follows:

The Landlord at:		000 Xxxxxx Xxx., Xxxxx 000 Xxxxxxx, Xxxxxxx X0X 0X0

The Landlord and the Tenant covenant and agree with each other that, save and except as specifically provided herein, this Lease Amending Agreement shall be on the same terms, conditions, covenants, agreements, obligations and provisos contained in the Lease insofar as the same shall be deemed to be incorporated herein and shall be binding upon the Landlord and the Tenant as though the “Landlord” and “Tenant” referred to in the Lease were the Landlord and Tenant respectively herein and that the Landlord and the Tenant shall respectively duly observe and perform the same. If there shall be any

conflict between the terms of the Lease and the terms hereof, the terms hereof shall apply.
