The duties to be performed by the Executive hereunder shall be performed primarily at the principal office of the Employer in the City of Montreal, Quebec, subject to reasonable travel requirements.

(c) During the Term, the Executive shall devote his full business time and his best efforts, business judgment, skill and knowledge exclusively to the advancement of the Business and interests of the Employer and its Affiliates and to the discharge of his duties and responsibilities hereunder. The Executive shall not engage in any other business activity or serve in any industry, trade, professional, governmental or academic position during the Term, except as may be approved by the Chief Executive Officer and Board. The foregoing provisions of this Section 3(c) shall not, however, preclude the Executive from devoting a reasonable amount of time to engaging in civic, charitable or religious activities, devoting a reasonable amount of time to private investment activities, serving as a director of one (1) outside board and/or serving as a director, officer or trustee of companies, trusts or foundations owned by, or of which the sole beneficiaries are, family members of the Executive, provided in each case that such involvement is in compliance with the provisions of Section 8(a) hereof and does not otherwise conflict with the Executive’s responsibilities to the Employer.

4. Compensation and Benefits. As compensation for all services performed by the Executive hereunder:

(a) Base Salary. The Employer shall pay the Executive an initial base salary at the rate of $375,000 dollars per annum, less all applicable withholdings, payable in accordance with the payroll practices of the Employer for its executives (the “Base Salary”). Such salary shall be reviewed annually but shall not be decreased during the Term.

(b) Annual Bonus. During the Term, with respect to each of the Employer’s fiscal years that begins on or after February 1, 2005, the Executive will be eligible to receive a bonus (the “Annual Bonus”) with a target of 100% of his Base Salary, except that, such Annual Bonus shall be pro rated for the fiscal year beginning on February 1, 2005 based on the number of days between the date of this agreement and the end of such fiscal year as compared to the total number of days in such fiscal year and shall not be lower than such pro rated portion of 85% of his Base Salary. The Annual Bonus will be based on the achievement of targets which shall be determined by the Board.

(c) Other Benefits. During the Term and subject to any contribution therefor generally required of executives of the Employer, the Executive shall be entitled to

participate in any and all employee benefit plans from time to time in effect for executives of the Employer generally. Such participation shall be subject to the terms of the applicable plan documents and generally applicable Employer policies. The Employer may alter, modify, add to or delete its employee benefit plans at any time as it, in its sole judgment, determines to be appropriate and the whole subject to applicable law. The Executive shall be entitled to paid vacation consistent with the Employer’s vacation policy (such vacation, however, not to be less than four (4) weeks per annum, pro rated for 2005) and reasonable holidays and illness days in accordance with the Employer’s policies as may be established and modified from time to time.

(d) Short-term Disability. Subject to Section 5(b), in the event the Executive becomes disabled during the Term through any illness, injury, accident or condition of either a physical or psychological nature, and, as a result, is unable to perform all his duties and responsibilities hereunder, the Employer will pay to the Executive the equivalent of the Executive’s Base Salary for the lesser of:

(e) Directors’ and Officers’ Insurance. The Employer shall provide to the Executive the benefit of at all times during the Term, and pay all of the costs of, the directors’ and officers’ liability insurance policy or policies obtained by the Employer, which shall cover the Executive for his service hereunder, whether as director, and/or officer of the Employer or as director and/or officer of any of the Employer’s Affiliates.

5. Termination of Employment and Severance Benefits. Notwithstanding the provisions of Section 2 hereof, the Executive’s employment hereunder shall terminate under the following circumstances:

(a) Death. In the event of the Executive’s death during the Term, the Executive’s employment hereunder shall immediately and automatically terminate. In such event, the Employer shall pay to the Executive’s designated beneficiary or, if no beneficiary has been designated by the Executive, to his estate, (i) the Base Salary earned but not paid through the date of termination, and (ii) any business expenses incurred by the Executive but not reimbursed on the date of termination, and (iii) any bonus compensation (other than Annual Bonus with respect to the fiscal year in which the date of termination occurs) awarded but unpaid on the date of termination; (iv) any outstanding vacation pay (collectively, “Final Compensation”); and (v) the portion of the Annual Bonus earned for the fiscal year in which the date of termination occurs, prorated for the time of the Executive’s employment during the relevant fiscal year (the “Prorated Bonus”), it being understood that the Prorated

-3-

Bonus will be paid following the end of the relevant fiscal year or such other time as per the Employer’s normal practice.

(b) Disability

(i) The Employer may terminate the Executive’s employment hereunder, upon written notice to the Executive, in the event that the Executive becomes disabled during his employment hereunder through any illness, injury, accident or condition of either a physical or psychological nature and, as a result, is unable to perform substantially all of his duties and responsibilities hereunder, with or without reasonable accommodation, for ninety (90) days during any period of one hundred eighty (180) consecutive calendar days. In the event of such termination, (a) if the Employer or its Affiliates then have in effect a Long Term Disability Plan, the Employer shall have no further obligation to the Executive, other than for payment of Final Compensation and any Prorated Bonus and (b) if neither the Company nor its Affiliates the have in effect a Long Term Disability Plan, the Employer shall have no further obligation to the Executive, other than for payment of amounts described in Section 5(d).

(ii) The Board may designate another employee to act in the Executive’s place during any period of the Executive’s disability. While receiving disability income payments under Employer’s disability income plan, the Executive shall continue to participate in Employer benefit plans, if any, in accordance with the terms of such plans, until the termination of his employment.

(c) By the Employer for Cause. The Employer may terminate the Executive’s employment hereunder immediately for Cause at any time upon written notice to the Executive setting forth in reasonable detail the nature of such Cause.

Upon the giving of notice of termination of the Executive’s employment hereunder for Cause, the Employer shall have no further obligation to the Executive, other than for Final Compensation and any requirement of applicable law.

(d) By the Employer Other than for Cause. The Employer may terminate the Executive’s employment at any time, other than for Cause, Death and Disability (but only, in the case of Disability, if the Company or its Affiliates then have in effect a Long Term Disability Plan) by (a) paying to the Executive Final Compensation and any Prorated Bonus; and (b) by providing the Executive with severance pay in lieu of notice representing the equivalent of the Executive’s Base Salary for twenty-four months, payable by way of salary continuance in accordance with the Employer’s payroll practices at the date of termination or in a lump sum payment, at the sole discretion of the Employer.

These obligations of the Employer to the Executive hereunder are conditional, however, upon the Executive signing a release, reasonably acceptable to the Employer, of any and all claims related to the employment of the Executive or the termination thereof.

(e) By the Executive for Constructive Termination. The Executive may terminate his employment hereunder immediately for Constructive Termination at any time upon

-4-

written notice to the Employer setting forth in reasonable detail the nature of the Constructive Termination. In the event of such termination, the Employer shall pay the Executive in accordance with Section 5(d).

Any obligation of the Employer to the Executive hereunder is conditional, however, upon the Executive signing a release, reasonably acceptable to the Employer, of any and all claims related to the employment of the Executive or the termination thereof.

(f) By the Executive other than for Constructive Termination. The Executive may terminate his employment hereunder at any time upon thirty days written notice to the Employer. In the event of termination of the Executive pursuant to Section 5(f), the Board may elect to waive the period of notice, or any portion thereof, provided the Employer pays the Executive to the term of the notice. The Employer shall then have no further obligation to the Executive, other than for Final Compensation due to him.

6. Effect of Termination. The provisions of this Section 6 shall apply to any termination of employment in accordance with Section 5.

(a) Payments or provision of benefits by the Employer pursuant to Section 5 shall constitute the entire obligation of the Employer to the Executive.

(b) Provisions of this Agreement shall survive any termination if so provided herein or if necessary or desirable to accomplish the purposes of other surviving provisions, including without limitation the obligations of the Executive under Sections 7, 8 and 9 hereof. The obligation of the Employer to make payments to the Executive under Section 5(b)(i)(b), 5(d) or 5(e) hereof is expressly conditioned upon the Executive’s continued full performance of obligations under Sections 7, 8 and 9 hereof. The Executive recognizes that, except as expressly provided in Section 5(b)(i)(b), 5(d) or 5(e), no compensation is earned after termination of employment.

7. Confidential Information.

(a) The Executive acknowledges that the Employer, its Affiliates and their predecessors have developed Confidential Information and that the Employer and its Affiliates continually develop Confidential Information, that the Executive may develop Confidential Information for the Employer and its Affiliates, that the Executive may learn of Confidential Information during the course of employment. The Executive will comply with the policies and procedures of the Employer and its Affiliates for protecting Confidential Information and shall not disclose to any Person or use, other than as required by applicable law or for the proper performance of his duties and responsibilities to the Employer and its Affiliates, any Confidential Information obtained by the Executive incident to his employment or other association with the Employer and its Affiliates, whether prior to, at the time of, or subsequent to any assignment of this Agreement pursuant to Section 16. The Executive understands that this restriction shall continue to apply after his employment terminates, regardless of the reason for such termination.

(b) All documents, records, tapes and other media of every kind and description relating to the Business, present or otherwise, of the Employer or its Affiliates and any

-5-

copies, in whole or in part, thereof (the “Documents”), whether or not prepared by the Executive, shall be the sole and exclusive property of the Employer and its Affiliates. The Executive shall safeguard all Documents and shall surrender to the Employer at the time his employment terminates, or at such earlier time or times as the Board or its designee may specify, all Documents then in the Executive’s possession or control.

8. Restricted Activities. The Executive agrees that some restrictions on his activities during and after his employment are necessary to protect the goodwill, Confidential Information and other legitimate interests of the Employer and its Affiliates:

(a) Non-Competition. While the Executive is employed by the Employer and for a period of twenty-four months after his employment terminates for any reason, the Executive shall not, directly or indirectly, engage in any business competitive with the Business within the Territory. However, no ownership of less than five percent of the outstanding stock of any publicly traded corporation will be deemed to be in violation of this Section 8(a) solely by reason thereof.

(b) Loyalty. The Executive agrees that, during his employment with the Employer, he will not undertake any outside activity, whether or not competitive with the Business, the Employer or its Affiliates, that could reasonably give rise to a conflict of interest or otherwise interfere with his duties and obligations to the Employer or any of its Affiliates.

(c) Non-Solicitation of Employees. The Executive further agrees that while he is employed by the Employer and during an twenty-four month period after his employment terminates for any reason, the Executive shall not, directly or indirectly, recruit, offer employment, employ, engage as a consultant, lure or entice away, or in any other manner persuade or attempt to persuade any Person who is an employee of Aris Import Inc. (hereinafter “Aris”), any Person employed by the Employer or its Affiliate as a store manager or in any other position of equal or greater responsibility, or any Person working in the corporate office of the Employer or its Affiliate, to leave the employ of the Employer, its Affiliate or Aris, as the case may be.

(d) Non-Solicitation of Suppliers. The Executive agrees that while he is employed by the Employer and during a eighteen months period after his employment terminates for any reason, the Executive shall not lure, entice away, or in any other manner persuade or attempt to persuade any Supplier to cease or materially reduce its business with the Employer or any of its Affiliates.

9. Assignment of Rights to Intellectual Property. The Executive shall promptly and fully disclose all Intellectual Property to the Employer. The Executive hereby assigns and agrees to assign to the Employer (or as otherwise directed by the Employer) the Executive’s full right, title and interest in and to all Intellectual Property. The Executive agrees to execute any and all applications for domestic and foreign patents, copyrights or other proprietary rights and to do such other acts (including without limitation the execution and delivery of instruments of further assurance or confirmation) requested by the Employer to assign the Intellectual Property to the Employer and to permit the Employer to enforce any patents, copyrights or other proprietary rights to the Intellectual Property. The Executive will not charge the Employer for time spent in

-6-

complying with these obligations. All copyrightable works that the Executive creates shall be considered work made in the course of employment.

10. Enforcement of Covenants. The Executive acknowledges that he has carefully read and considered all the terms and conditions of this Agreement, including the restraints imposed upon him pursuant to Sections 7, 8 and 9 hereof. The Executive agrees that said restraints are necessary for the reasonable and proper protection of the Employer and its Affiliates and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area. The Executive further acknowledges that, were he to breach any of the covenants contained in Sections 7, 8 and 9 hereof, the damage to the Employer would be irreparable. The Executive therefore agrees that the Employer, in addition to any other remedies available to it, shall be entitled to preliminary and permanent injunctive relief against any breach or threatened breach by the Executive of any of said covenants, without having to post security.
