OF THE SECOND PART

WHEREAS the Corporation is desirous of retaining the services of the Executive as an employee of the Corporation and as its Executive;

AND WHEREAS the Executive has agreed to enter into and deliver this Agreement on the terms and conditions contained herein.

AND WHEREAS the Executive has agreed to enter into and deliver this Agreement in consideration of receiving certain additional benefits and other additional compensation as provided for pursuant to the terms of this Agreement;

NOW THEREFORE THIS AGREEMENT WITNESSES that in consideration of the mutual covenants and agreements herein contained and for other good and valuable consideration, the parties agree as follows:

For the purposes of this Agreement, the following terms shall have the following meanings, respectively:

(for the purposes of this definition and this Agreement, whether persons are affiliated or associated shall be determined in accordance with the definitions of “Affiliate” and “Associate” in the provisions of the Act as such provisions may be amended, supplemented or replaced from time to time and for purposes of this definition the terms “group” and “beneficial ownership” shall have the meanings ascribed thereto under Section 14(d)(2) of the Securities Act and Rule 13d-3 of the General Rules of the Securities Act, respectively);

The Corporation shall employ the Executive for an indefinite period commencing on the date of this Agreement, subject, however, to earlier termination as hereinafter provided.

The Executive shall serve the Corporation and any subsidiaries of the Corporation in such capacity or capacities and shall perform such duties and exercise such powers pertaining to the management and operation of the Corporation and any Subsidiaries and Associates of the Corporation (as those terms are defined in the Act) as may be determined from time to time by the Reporting Manager (as defined below) and the Chief Executive Officer (“CEO”) consistent with the office of the Executive. The Executive shall:

The Executive shall report to the President/CEO (“Reporting Manager”). The Executive shall report fully on the management, operations and business affairs of the Corporation and advise to the best of his ability and in accordance with business standards on business matters that may arise from time to time during the term of this Agreement.

In addition to the Executive’s Annual Base Salary, the Executive shall be entitled to earn a bonus (the “Performance Bonus”) which shall be based upon performance goals established by the Reporting Manager in conjunction with the CEO (and the Compensation Committee, as may be required) from time to time and set forth in a separate document. Any changes respecting the amount or other terms of the Performance Bonus payable to the Executive must be approved by the Reporting Manager in conjunction with the CEO (and the Compensation Committee, as may be required). As of the date of this Agreement, the Performance Bonus target is CDN$230,000.00.

Other than as herein provided, there shall be no cost-of-living increase or merit increase in the Annual Base Salary or increases in any bonuses payable to the Executive unless agreed to in writing by the Reporting Manager and the CEO. The Reporting Manager and the CEO shall review annually the Annual Base Salary and all other compensation to be received by the Executive under this Agreement.

The Corporation shall permit the Executive to participate in any share option plan, share purchase plan, retirement plan or similar plan offered by the Corporation from time to time to its senior executives in the manner and to the extent authorized by the Compensation Committee of the Board of Directors. The Compensation Committee may, in its absolute discretion, grant additional options, subject to approval by the Board of Directors, and it may review the advisability of additional option grants for the Executive.

The Executive shall be entitled to (5) Five weeks paid vacation per fiscal year of the Corporation at a time approved in advance by the Reporting Manager, which approval shall not be unreasonably withheld but shall take into account the staffing requirements of the Corporation and the need for the timely performance of the Executive’s responsibilities. Any vacation entitlement hereunder shall be subject to the Corporation’s policy respecting same in effect from time to time.

Subject to the terms of this section, the Executive shall be reimbursed for all reasonable travel and other out-of-pocket expenses actually and properly incurred by the Executive from time to time in connection with carrying out his duties hereunder. Determination of whether expenses are reasonable or not shall be made by the Reporting Manager. For all such expenses the Executive shall furnish to the Corporation originals of all invoices or statements in respect of which the Executive seeks reimbursement.

The Corporation may immediately terminate the employment of the Executive for Just Cause without notice or any payment in lieu of notice, and for purposes of greater certainty, the Corporation shall have no obligation to make any payments to the Executive on account of severance or bonuses or partial bonuses or any other amounts except as expressly stipulated in Section 12(a) hereof.

This Agreement may be immediately terminated by the Corporation by notice to the Executive if the Executive is determined to suffer from disability. The Executive shall be deemed to suffer from disability (hereinafter referred to as “Disability”) if in any year during the employment period, because of ill health, physical or mental disability, or for other causes beyond the control of the Executive, the Executive has been continuously unable or unwilling or has failed to perform the Executive’s duties for 120 consecutive days, or if, during any year of the employment period, the Executive has been unable or unwilling or has failed to perform his duties for a total of 180 days, consecutive or not. The CEO, acting reasonably, shall (subject to paragraph 31 herein), finally determine if the Executive is suffering from ill health, physical or mental disability or other causes beyond his control during the time periods as hereinbefore set forth in the event of any dispute between the Executive and the Corporation concerning the occurrence of Disability for purposes of this Section.

Notwithstanding any short term or long term corporate benefits or insurance policies relating to disability maintained by the Corporation at the relevant time, if during any period of ill health, physical or mental disability or for other causes beyond the control of the Executive, the Executive has been continuously unable or unwilling or has failed to perform the Executive’s duties less than 120 consecutive days (the “Short-Term Illness”), the Executive shall continue to receive all amounts of remuneration and benefits otherwise payable to and enjoyed by the Executive under this Agreement less any and all amounts received by and/or payable to the Executive in connection with benefits paid and/or payable as a result of such Short-Term Illness (i.e. no duplicate payments as a result of short term disability payments and the Executive’s salary payments that are due during the Short-Term

Illness time period). Upon termination of this Agreement as a result of Disability, the Corporation shall pay to the Executive the severance payment provided for in Subsection 12(b) hereof less any and all amounts received by and/or payable to the Executive in connection with benefits paid and/or payable as a result of the Disability. Upon termination of this Agreement as a result of Disability, the Corporation shall permit the Executive to continue to participate in those employee benefits referred to in Section 5(b) hereof, to the extent enjoyed by the Executive prior to the occurrence of Disability, for the number of months of severance payments set forth in the chart on Exhibit 1. The term “any year of the employment period” means any period of 12 consecutive months during the employment period.

This Agreement shall terminate without notice or any payment in lieu thereof immediately upon the death of the Executive.

If the Executive is desirous of voluntarily terminating his employment with the Corporation, the Executive agrees to give the Corporation 3 months advance written notice of such termination in which case the Executive shall not be entitled to any payment on account of severance under Section 12(b) hereof. The Reporting Manager and the CEO may waive such notice in writing after consulting with the Board of Directors, in their sole and absolute discretion, in which case the Executive’s employment shall be deemed to terminate immediately, provided the Executive shall still be entitled to compensation due on account of Annual Base Salary and benefits earned up to the last date of the 3 month advance written notice period given by the Executive and any Performance Bonus earned and prorated during such 3 month notice period. Provided that the Executive gives the 3 month notice as required hereunder, any unvested options which would have otherwise vested during such advance written notice period shall be permitted to continue to vest during such period. The Executive shall have the right to exercise any options which are vested as at the Date of Termination for the period which is 90 days following such Date of Termination (the “90 Day Period”). For purposes of this Section 11(c), the term “Date of Termination” shall mean the actual day on which the Executive ceases to be employed plus the remainder of the 3 month notice period if and to the extent waived by the Reporting Manager and the CEO in consultation with the Board of Directors. Any termination properly given under Section 14(b) hereof and in accordance with the terms thereof shall not be considered a voluntary termination under this Section 11(c).

The Corporation may terminate the employment of the Executive, notwithstanding any other provision of this Agreement, upon compliance with the terms of Section 12(b) hereof.

If, at the Date of Termination, there were any memberships in any clubs, social or athletic organizations paid for by the Corporation pursuant to Schedule A hereof at the Date of Termination, the Corporation will not take any action to terminate such memberships but will not renew any such membership that expires or reimburse the Executive for any further payments thereunder.

Any amounts due hereunder on account of severance in 12.b.(iii) and 12.b.(iv) above shall be paid by the Corporation to the Executive on a monthly basis commencing 30 days following the Date of Termination and not in a lump sum.

the Executive, the estate of the Executive shall be entitled, at any time during the period which is 12 months following the date of death of the Executive (the “12 Month Period”), to exercise any options which have vested as at the date of death of the Executive. In addition, any unvested options which would have otherwise vested during such 12 Month Period shall continue to vest during that period and to the extent of any unvested options have vested during such period, the Executive’s estate shall be entitled to exercise those options within a period which starts on the day of vesting and ends 12 months from the date of death of the Executive.

For purposes of greater certainty, if the Executive is terminated for Just Cause, Death or if the Executive’s employment hereunder is terminated by the Executive pursuant to Section 11(c) then no payment whatsoever shall be made to the Executive under Section 12(b).

Except as expressly provided in Sections 11 and 12 above and Section 14 below, where the Executive’s employment has been terminated by the Executive or terminated or deemed to have been terminated by the Corporation for any reason, the Executive will not be entitled to receive any further payments, in lieu of notice or as damages for any reason whatsoever. Except as to any entitlement as expressly provided in this Agreement, the Executive hereby waives any claims the Executive may have against the Corporation for or in respect of termination pay, severance pay, or on account of loss of office or employment or notice in lieu thereof, or any other cause, including human rights legislation.

If the Executive’s employment is terminated by the Corporation upon the giving of written notice of such termination to the Executive at any time within the 6 month period following a Change of Control (other than for Just Cause, Disability or Death), then the Executive shall be entitled to the following:

If the Executive’s employment is terminated by the Executive upon the giving of written notice of such termination to the Corporation within the 6 month period following a Change of Control, and within 60 days following the occurrence of a Parachute Event, which shall be described in detail by the Executive in the written notice of termination given to the Corporation, the Executive shall be entitled to the following:

During the employment period, the Executive shall promptly disclose to the CEO full information concerning any interest, direct or indirect, of the Executive (as owner, shareholder, partner, lender or other investor, director, officer, employee, consultant or otherwise) or any member of his family in any business that is reasonably known to the Executive to purchase or otherwise obtain services or products from, or to sell or otherwise provide services or products to the Corporation or to any of its suppliers or customers.

The Executive agrees to execute contemporaneously with his execution of this Agreement the confidentiality, non-solicitation, non-competition and inventions/proprietary rights agreement in substantially the form annexed hereto as Schedule “B”.

All files, forms, brochures, books, materials, written correspondence, memoranda, documents, manuals, computer disks, software products and lists (including lists of customers, suppliers, products and prices) pertaining to the business of the Corporation or any of its subsidiaries and associates that may come into the possession or control of the Executive shall at all times remain the property of the Corporation or such Subsidiary or Associate, as the case may be. On termination of the Executive’s employment for any reason, the Executive agrees to deliver promptly to the Corporation all such property of the Corporation in the possession of the Executive or directly or indirectly under the control of the Executive. The Executive agrees not to make for his personal or business use or that of any other party, reproductions or copies of any such property or other property of the Corporation.

This agreement shall be governed by and construed in accordance with the laws of the Province of Ontario.

If any provision of this agreement, including the breadth or scope of such provision, shall be held by any court of competent jurisdiction to be invalid or unenforceable, in whole or in part, such invalidity or unenforceability shall not affect the validity or enforceability of the remaining provisions, or part thereof, of this agreement and such remaining provisions, or part thereof, shall remain enforceable and binding.

The Executive hereby confirms and agrees that the covenants and restrictions pertaining to the Executive contained in this Agreement, are reasonable and valid and hereby further acknowledges and agrees that the Corporation would suffer irreparable injury in the event of any breach by the Executive of his obligations under any such covenant or restriction. Accordingly, the Executive hereby acknowledges and agrees that damages would be an inadequate remedy at law in connection with any such breach and that the Corporation shall therefore be entitled in lieu of any action for damages, temporary and permanent injunctive relief enjoining and restraining the Executive from any such breach.

The Executive may not assign, pledge or encumber the Executive’s interest in this agreement nor assign any of the rights or duties of the Executive under this agreement without the prior written consent of the Corporation.

This agreement shall be binding on and enure to the benefit of the successors and assigns of the Corporation and the heirs, executors, personal legal representatives and permitted assigns of the Executive.

Any notice or other communication required or permitted to be given hereunder shall be in writing and either delivered by hand or mailed by prepaid registered mail. At any time other than during a general discontinuance of postal service due to strike, lock-out or otherwise, a notice so mailed shall be deemed to have been received three business days after the postmarked date thereof or, if delivered by hand, shall be deemed to have been received at the time it is delivered. If there is a general discontinuance of postal service due to strike, lock-out or otherwise, a notice sent by prepaid registered mail shall be deemed to have been received three business days after the resumption of postal service. Notices shall be addressed as follows:

The Executive hereby represents and warrants to the Corporation and acknowledges and agrees that he had the opportunity to seek and was not prevented nor discouraged by the Corporation from seeking independent legal advice prior to the execution and delivery of this agreement and that, in the event that he did not avail himself of that opportunity prior to signing this agreement, he did so voluntarily without any undue pressure and agrees that his failure to obtain independent legal advice shall not be used by him as a defence to the enforcement of his obligations under this agreement.

The Executive agrees that after termination of his/her employment, he/she will, at the request of the CEO, tender his/her resignation from any position he/she may hold as an officer or director of the Corporation or any of its Affiliated or Associated companies, and the Executive further covenants and agrees, if so requested by the CEO, not to stand for re-election to any office of the Corporation or any of its Affiliated or Associated companies at any time following termination of the Executive’s employment hereunder.

Nothing herein derogates from any rights the Executive may have under applicable law, except as set out in this section. The parties agree that the rights, entitlements and benefits set out in this Agreement to be paid to the Executive are in full satisfaction of any rights or entitlements the Executive may have as against subsidiaries of the Corporation as a result of the termination of his employment with such subsidiaries.

All dollars referenced herein are in Canadian dollars unless expressly provided to the contrary.

The Executive covenants and agrees that he shall not engage in any pattern of conduct that involves the making or publishing of written or oral statements or remarks (including, without limitation, the repetition or distribution of derogatory rumours, allegations, negative reports or comments) which are disparaging, deleterious or damaging to the integrity, reputation or goodwill of the Corporation, its affiliates or its and their management.

The Executive acknowledges and agrees that the Corporation may collect, use and disclose his personal information for purposes relating to his employment with the Corporation. The purposes of such collection, use and disclosure include, but are not limited to:

(a) ensuring that the Executive is paid for his services to the Corporation which includes disclosure to third party payroll providers;

(b) administering and/or facilitating the provision of any benefits to which the Executive is or may become entitled to, including bonuses, medical, dental, disability and life insurance benefits, pension, group RRSP and/or stock options. This shall include the disclosure of the Executive’s personal information to the Corporation’s third party service providers and administrators;

(c) compliance by the Corporation with any regulatory reporting and withholding requirements relating to the Executive’s employment;

(d) in the event of a sale or transfer of all or part of the shares or assets of the Corporation, disclosing to any potential acquiring organization the Executive’s personal information solely for the purposes of determining the value of the Corporation and its assets and liabilities and to evaluate the Executive’s position in the Corporation. If the Executive’s personal information is disclosed to any potential acquiring organization, the Corporation will require the potential acquiring organization to agree to protect the privacy of the Executive’s personal information in a manner that is consistent with any policy of the Corporation dealing with privacy that may be in effect from time to time and/or any applicable law that may be in effect from time to time;

(e) compliance by the Corporation of its obligations to report improper or illegal conduct by any of its directors, officers, employees or agents under any applicable securities, criminal or other law; and

(f) monitoring the Executive’s access to the Corporation’s electronic media services in order to ensure that the use of such services is in compliance with the Corporation’s policies and procedures and is not in violation of any applicable laws.

If the Executive’s specific consent to the collection, use or disclosure of his personal information is required in the future, the Executive hereby agrees to provide such consent, and if the Executive refuses to provide or withdraws his consent, the Executive acknowledges that his employment and/or his entitlement to certain employment benefits may be negatively affected.

This Agreement constitutes the entire agreement and understanding between the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings, written or oral, among the parties relating to such subject matter, including any other employment agreement made between the Corporation and the Executive.

If there is a disagreement or dispute between the parties with respect to this Agreement or the interpretation thereof, such disagreement or dispute will be referred to binding arbitration to be conducted by a single arbitrator, if Executive and the Corporation agree upon one, otherwise by three arbitrators appointed as hereinafter set out, pursuant to the provisions of the Arbitrations Act 1991 (Ontario) and any amendments thereto. A party who wishes to arbitrate shall give written notice of such intention to the other party (a “Notice of Intention”). The arbitrator shall be appointed by agreement by agreement of

Executive and the Corporation or, in default of agreement within ten (10) Business Days of service of the Notice of Intention, each of Executive and the Corporation shall within five (5) Business Days of the expiry of the aforesaid ten (10) Business Day period, select one arbitrator and notify the other of its selection, with the third arbitrator to be chosen by the first two named arbitrators within five (5) Business Days of the expiry of the aforesaid five (5) Business Day period. If one of the parties does not so notify the other of its selection within the prescribed time, then the arbitrator selected by the other party in accordance with the above procedure shall be the sole arbitrator. The arbitration shall be held in the City of Toronto. The procedure to be followed shall be as agreed by the parties or, in default of agreement, determined by the arbitrator(s), provided, however, that depositions or examinations for discovery will not be allowed but information may be exchanged by other means. The parties will use their best efforts to ensure that the arbitration hearing is conducted no later than sixty (60) days after the arbitrator is, or arbitrators are, selected. The final decision of the arbitrator or arbitrators or any two of the three arbitrators will be furnished to the parties in writing and will constitute a conclusive determination of the issue in question, binding upon the parties, without right of appeal. The fees and expenses of the arbitration shall be in the discretion of the arbitrator(s). Judgment upon the award may be entered in any court of competent jurisdiction.

The Executive represents and warrants that none of the negotiation, entering into or performance of this Agreement has resulted in or may result in a breach by the Executive of any agreement, duty or other obligation with or to any Person, including, without limitation, any agreement, duty or obligation not to compete with any Person or to keep confidential the confidential information of any Person, and there exists no agreement, duty or other obligation binding upon the Executive that conflicts with the Executive’s obligations under this Agreement. The Executive agrees to indemnify and hold the Corporation, its officers, directors, employees, agents and consultants harmless against any and all claims, liabilities, damages or costs incurred by any of them by reason of an alleged violation by the Executive of the representations contained in this Section.
