4.6 Resignation from All Positions

Page 9

The Corporation shall be obligated to provide such release to the Executive promptly following the Date of Termination.

ARTICLE 6

RESTRICTIVE COVENANTS

6.1 In General

The Executive acknowledges that in the course of his employment he will become familiar with trade secrets and customer lists of and other confidential information concerning the Affiliated Group and that his services have been of special, unique and extraordinary value to the Affiliated Group.

6.2 Confidentiality Undertaking

The Executive confirms that he is bound by the provisions of the Confidentiality Undertaking covenant set out in Schedule B hereto.

6.3 Non-Solicitation/No-Hire

(a) During the six (6) month period immediately following the Date of Termination, the Executive shall not in any manner, directly or indirectly, hire, solicit, induce or attempt to solicit or induce any employee of any member of the Affiliated Group to quit or abandon his or her employ or to become an officer, agent, employee, partner, director, consultant or independent contractor of the Executive, his affiliates or any other individual or entity.

(b) During the six (6) month period immediately following the Date of Termination, the Executive shall not in any manner, directly or indirectly, hire, solicit, induce or attempt to solicit or induce, any customer, supplier or licensor of any member of the Affiliated Group to cease doing business with any member of the Affiliated Group, or in any way interfere with the relationships between any customer, supplier or licensor of the Affiliated Group.

6.4 Non-Competition

During the six (6) month period immediately following the Date of Termination, the Executive shall not in any manner, directly or indirectly, compete with the business of any member of the Affiliated Group by (a) becoming an officer, agent, employee, partner, director, consultant, independent contractor of a Competitor, or (b) acquiring an ownership interest in a Competitor, provided that the Executive may, for investment purposes, own not more than 1% of the outstanding stock of any class of a Competitor that is listed on a recognized stock exchange or traded in the over-the-counter market in

Page 10

Canada or the United States. For purposes of this Agreement, the term “Competitor’ means any person or entity that engages in the pharmaceutical development and/or manufacturing outsourcing business in Canada, the United States (including the Commonwealth of Puerto Rico), India or Europe.

6.5 Reasonableness and Revision

The Executive agrees and acknowledges that due to the uniqueness of his services and the confidential nature of the information he will possess, the covenants set forth in this Article 6 and Schedule B are reasonable and necessary for the protection of the business interests and goodwill of the Affiliated Group. Moreover, the geographic restriction on competitive activities by the Executive is reasonable, given the global nature of the Affiliated Group’s business and the Executive’s role in that business. if, at the time of enforcement of this Article and/or Schedule B, a court or other tribunal holds that the restrictions herein are in whole or in part unreasonable under circumstances then existing, the parties agree that the maximum period or scope reasonable under such circumstances will be substituted for the stated period or scope and that the court or other tribunal shall be authorized and directed by the parties to revise the restrictions contained herein to cover the maximum period or scope permitted by law.

6.6 Acknowledgements

The Executive agrees and acknowledges that the promises and obligations made by the Corporation in this Agreement (specifically including, but not limited to, the payments and benefits provided for under Section 5.1(b) and (d) hereof) constitute sufficient consideration for the covenants contained in this Article 6. The Executive further acknowledges that it is not the Affiliated Group’s intention to interfere in any way with his employment opportunities, except in such situations where the same conflict with the legitimate business interests of the Affiliated Group. The Executive agrees that he will notify the Corporation in writing if he has, or reasonably should have, any questions regarding the applicability of this Article 6.

6.7 Enforcement

Because the Executive’s services are unique and because the Executive has access to Confidential Information and work product, the parties agree that the Affiliated Group will be damaged irreparably in the event any of the provisions of Section 6.2, 6.3 and 6.4 are not performed in accordance with their specific terms or are otherwise breached and that money damages will be an inadequate remedy for any such non-performance or breach. Therefore, any one or more of the members of the Affiliated Group, or their respective successors and assigns, will be entitled, in addition to other rights and remedies existing in their favor, to an injunction or injunctions to prevent any breach or threatened breach of any of such provisions and to enforce such provisions specifically (without posting a bond or other security). The Executive agrees and acknowledges that he will not assert in any such enforcement action that there is an adequate remedy in damages and that such rights and remedies will be in addition to and not in lieu of any other rights or remedies available to the Affiliated Group at law or in equity.

6.8 Survival

Subject to any limits on applicability contained therein, this Article 6 shall survive and continue in full force in accordance with its terms notwithstanding any expiration or termination of this Agreement.

(b) If neither the “short-term deferral” or the involuntary separation pay exceptions to Section 409A described above applies to a benefit, payment or reimbursement under this Agreement, then notwithstanding any provision in this Plan to the contrary, the remaining provisions of this Section 7.8(b) shall apply.

The Executive shall not, either during the term of the Agreement or at any time thereafter, use or disclose, directly or indirectly, any of such Confidential Information to any person outside the Affiliated Group, except where such disclosure is necessary for the proper and bona fide execution of the Executive’s duties under the Agreement, without the prior written consent of the Affiliated Group. The Executive’s obligation not to use or disclose Confidential Information without prior written consent shall continue to apply after the Executive has ceased to be an employee of the Affiliated Group until such time as the Confidential Information becomes public knowledge through no fault of the Executive. The Affiliated Group will have full right, title and authority to deal in and with the proprietary rights and the Confidential Information notwithstanding any other provision of the Agreement or the termination thereof for any reason whatsoever. The Executive acknowledges and agrees that the restrictions contained in this Article 1 are reasonable in the circumstances in order to protect the business of the Affiliated Group.
