CONFIDENTIAL INFORMATION

7.1 Protection of Confidential Information. All Confidential Information, whether it is developed by the Employee during the Employment Period or by others employed or engaged by or associated with the Company or its affiliates or clients, is the exclusive and confidential property of the Company or its affiliates or clients, as the case may be, and will at all times be regarded, treated and protected as such, as provided in this Agreement.

7.2 Covenants Respecting Confidential Information. As a consequence of the acquisition of Confidential Information, the Employee will occupy a position of trust and confidence with respect to the affairs and business of the Company and its affiliates and clients. In view of the foregoing, it is reasonable and necessary for the Employee to make the following covenants regarding the Employee's conduct during and subsequent to the Employee's employment by the Company.

7.3 Non Disclosure. At all times during and subsequent to the Employee's employment with the Company, the Employee will not disclose Confidential Information to any Person (other than as necessary in carrying out the Employee's duties on behalf of the Company) without first obtaining the Company's consent, and the Employee will take all reasonable precautions to prevent inadvertent disclosure of any Confidential Information.

7.6 Obligations Continue. The Employee's obligations under this Part 7 are to remain in effect in perpetuity.

PART 8

INTELLECTUAL PROPERTY

8.1 Ownership. All Developments will be the exclusive property of the Company and the Company will have sole discretion to deal with Developments. For greater certainty, all work done during the Employment Period by the Employee for the Company or its affiliates is a work for hire of which the Company or its affiliate, as the case may be, is the first author for copyright purposes and in respect of which all copyright will vest in the Company or the relevant affiliate, as the case may be.

8.2 Records. The Employee will keep complete, accurate and authentic notes, reference materials, data and records of all Developments in the manner and form requested by the Company. All these materials will be Confidential Information upon their creation.

8.3 Moral Rights. The Employee hereby irrevocably waives all moral rights arising under statute in any jurisdiction or under common law which the employee may have now or in the future with respect to the Developments, including, without limitation, any rights the Employee may have to have the Employee's name associated with the Developments or to have the Employee's name not associated with the Developments, any rights the Employee may have to prevent the alteration, translation or destruction of the Developments, and any rights the Employee may have to control the use of the Developments in association with any product, service, cause or institution. The Employee agrees that this waiver may be invoked by the Company, and by any of its authorized agents or assignees, in respect of any or all of the Developments and that the Company may assign the benefit of this waiver to any Person.

8.4 Further Assurances. The Employee will do all further things that may be reasonably necessary or desirable in order to give full effect to the foregoing. If the Employee's co-operation is required in order for the Company to obtain or enforce legal protection of the Developments following the termination of the Employee's employment, the Employee will provide that co-operation so long as the Company pays to the Employee reasonable compensation for the Employee's time at a rate to be agreed, provided that the rate will not be less than the last base salary or compensation rate paid to the Employee by the Company during the Employee's employment.

8.5 Obligations Continue. The Employee's obligations under this Part 8 are to remain in effect in perpetuity.

PART 9

CONSENT TO ENFORCEMENT

The Employee confirms that all restrictions in Part 7 and 8 are reasonable and valid and all defences to the strict enforcement thereof by the Company are waived by the Employee. Without limiting the generality of the forgoing, the Employee hereby consents to an injunction being granted by a court of competent jurisdiction in the event that the Employee is in any breach of any of the provisions stipulated in Part 7 and 8. The Employee hereby expressly acknowledges and agrees that injunctive relief is an appropriate and fair remedy in the event of a breach of any of the said provisions.

PART 10

WARRANTIES, COVENANTS AND REMEDIES

10.1 The obligations of the Employee as set forth in Parts 6 through 9 will be deemed to have commenced as of the date on which the Employee was first employed by Company. The Employee warrants that the Employee has not, to date, breached any of the obligations set forth in any of those Sections. Any breach or threatened breach of those sections by the Employee will constitute Just Cause for immediate termination of the Employee's employment or engagement by the Company.

10.2 The Employee understands that the Company has expended significant financial resources in developing its products and the Confidential Information. Accordingly, a breach or threatened breach by the Employee of any of Parts 6 through 9 could result in unfair competition with the Company and could result in the Company and its shareholders suffering irreparable harm that is not capable of being calculated and that cannot be fully or adequately compensated by the recovery of damages alone. Accordingly, the Employee agrees that the Company will be entitled to interim and permanent injunctive relief, specific performance and other equitable remedies, in addition to any other relief to which the Company may become entitled.

10.3 The Employee's obligations under each of Parts 6 through 9 are to remain in effect in accordance with each of their terms and will exist and continue in full force and effect despite any breach or repudiation of this Agreement or the Employee's employment (including, without limitation, the Employee's wrongful dismissal) by the Company.

PART 11

The Company, at its sole discretion, may elect to accept the 60 Business Days written notice or to reduce or eliminate the notice period. In such event, the Employee's employment shall terminate on the earlier day elected by the Company. Such election on the part of the Company will not alter the nature of the termination as voluntary and the Company will not be required to pay any severance or termination payments in respect of a termination by the Employee under this Section 11.1.

11.3 Termination by the Company for Just Cause.

(c)

upon any such termination, all bonuses or other benefits earned or accrued up to the date of termination or expiry shall be paid by the Company, but except for such payments and the payments to be made pursuant to Sections 11.4(a) or (b), as applicable, all obligations of the Company under this Agreement shall end upon such termination or failure to renew. Payments under Sections 11.4(a) or (b) shall be payable monthly subject to deductions in Section 3.9.

11.5 Termination by the Employee for Good Reason. The Employee may terminate this Agreement at any time upon the occurrence of any of the following events (each a "Good Reason"), if such occurrence takes place without the express written consent of the Employee:

(i)

a change in the Employee's title or position or a material diminution in the Employee's duties or the assignment to the Employee of duties which materially impairs the Employee's ability to function in his current capacity for the Company, or, with respect to an assignment of duties only, is materially inconsistent with his duties;

(ii)

any material change in the Employee's direct reporting obligations;
