If the Subtenant does not exercise such right within such period, the Sublandlord shall be free to sublet such space on the terms set out in such third party offer. 9.

Sublandlord's Covenants Subject to the due performance by the Subtenant of its obligations herein, the Sublandlord covenants and agrees with the Subtenant: (a) for quiet enjoyment of the Sublet Premises, and the Sublandlord represents and warrants to the Subtenant (and acknowledges that the Subtenant, in entering into this Sublease, is relying thereon), that the Head Lease is in full force and effect and is unamended and the Sublandlord has fulfilled all of its obligations to date under the Head Lease and is not in default thereunder; (b) to enforce against the Head Landlord for the benefit of the Subtenant, its permitted successors and assigns and other lawful occupants of the Sublet Premises the covenants and obligations of the Head Landlord under the Head Lease with the intent that the benefit of such covenants and obligations shall extend to the Sublet Premises and be enjoyed by the Subtenant, its permitted successors and assigns and other lawful occupants; -8- (c) to observe and perform all of the obligations of the Sublandlord under this Sublease; (d) to pay all Rent and other amounts payable under the Head Lease and to duly observe and perform all of the obligations of the Tenant under the Head Lease except to the extent such obligations are to be observed and performed by the Subtenant under this Sublease; (e) to immediately notify the Subtenant in writing of any default in the payment of Rent by the Sublandlord to the Head Landlord or any other default of the Sublandlord under the Head Lease which is not or which cannot be remedied in accordance with the terms of the Head Lease and which default, may or does result in the Head Landlord terminating the Head Lease; (f) Contemporaneously with the delivery of the Head Landlord's consent to this Sublease by the Head Landlord, the Sublandlord agrees to post an irrevocable standby demand letter of credit from a Canadian chartered bank in favour of the Subtenant in the amount of CDN$250,000 in the form attached as Schedule C, (the "Subtenant Letter of Credit") for the whole of the Subterm. The Subtenant Letter of Credit may be for a term of not less than one (1) year and shall provide for successive automatic one (1) year extensions. If the Subtenant receives notice from the issuing bank or otherwise becomes aware that the Subtenant Letter of Credit will not be extended in accordance with its terms, the Subtenant shall be entitled to immediately draw down the full amount of the Subtenant Letter of Credit and hold and apply the amount so drawn as provided below in substitution for the Subtenant Letter of Credit, and the Sublandlord will not be entitled to any interest on the amount so held by the Subtenant.

Upon receiving from the Sublandlord written notice as set out in (iii) above, then, not later than thirty (30) days prior to the expiry of the Subterm, the Sublandlord will either make a cash payment to the Subtenant in the amount of $250,000, or if -9- it shall fail to do so, the Subtenant may immediately draw down the entire amount of the Subtenant Letter of Credit, and it may retain the cash payment or the proceeds of the Subtenant Letter of Credit for its sole benefit as agreed compensation for the estimated additional costs which the Subtenant may incur to lease premises at another location, relocate its business, and for the disruption of its business and consequent loss of profit, whether or not any or all of such additional costs or loss are actually suffered or incurred. For greater certainty, the Sublandlord agrees that the Subtenant Letter of Credit and the Subtenant's rights under this paragraph will not be released, discharged or affected in any way by the bankruptcy, receivership or insolvency of the Sublandlord, by a disclaimer of the Head Lease or this Sublease by any trustee in bankruptcy, or by the Sublandlord ceasing to exist (whether by winding up, forfeiture, cancellation or surrender of its charter, merger or any other circumstances); (g) to permit the use by the Subtenant of certain segments of the Intrusion Detection/Access Control System to be designated by the Sublandlord as such relate to the Sublet Premises, at no cost to the Sublandlord.

(the "Sublandlord Brokers"), and it agrees to indemnify and hold the Subtenant and Head Landlord harmless from and against any claims or causes of action for a commission or other form of compensation arising from this Sublease, whether advanced by the Sublandlord Brokers or any other person or entity. The provisions of this paragraph shall survive the termination of the Head Lease, this Sublease and any renewal or extension of either or both of them. 14. Use and Access Notwithstanding the definitions of "Permitted Use" and "Business" contained in the Head Lease, the Head Landlord and the Sublandlord agree that the Subtenant shall be permitted to use the Sublet Premises for the purposes of general business offices, which may include without limitation software sales (it being agreed and understood, however, that the Sublet Premises may not be used for commercial sales to the general public), marketing and development, and a software development computer laboratory in the Laboratory Space.

Subtenant's Assigning, Subletting, Etc. The Subtenant agrees that with respect to any assigning or subletting by it, the provisions of the Head Lease apply with the following amendments thereto: (a) each reference to the Landlord, the Tenant, the Lease and the Leased Premises shall become, respectively, the Sublandlord, the Subtenant, the Sublease and the Sublet Premises; and -11- (b) the Sublandlord shall have the additional right to withhold and/or delay its consent if it has not received the consent of the Head Landlord. 18. Other Terms of Head Lease Incorporated Subject to the provisions of this Sublease, the specific sections of the Head Lease which are incorporated elsewhere in this Sublease and subject to the exceptions to subsection 112(a), all of the terms of the Head Lease are also incorporated, mutatis mutandis, into and apply to this Sublease with each reference to the Landlord in the Head Lease being deemed to include both the Head Landlord and the Sublandlord and with each reference therein to the Tenant being deemed to mean the Subtenant. If any term of this Sublease is inconsistent with any term of the Head Lease, the term of this Sublease shall prevail. 19. Exercise of Rights Subject to the provisions of this Sublease, the exercise by the Head Landlord of any of its rights contained in the Head Lease shall, upon written notice by the Head Landlord to the Subtenant of such exercise, be binding upon the Subtenant. Notwithstanding the exercise by the Head Landlord of any of its rights contained in the Head Lease, the Sublandlord may also exercise its rights hereunder in the same manner as the Head Landlord. 20. Termination of Head Lease Subject to the provisions of this Sublease, the Subtenant acknowledges and agrees that it has no greater interest in the Sublet Premises than the Sublandlord under the Head Lease. 21.
