Executive understands that for benefit plans governed by the Employee Retirement Income Security Act of 1974 (ERISA) and equity or similar awards granted by the Company, his eligibility (if any) for such benefits and equity or similar awards shall be determined in accordance with the terms of the applicable plan or other governing documents.

Executive agrees to refrain from directly or indirectly engaging in publicity, including written, oral and electronic communication of any kind, or any other activity which reflects negatively or adversely upon the Company or any of its affiliated or related entities, their businesses, their actions or their officers, directors or employees, whether or not he believes the content of the publicity to be true and whether or not it is, in fact, true. The Company likewise agrees to refrain from engaging in publicity or authorizing statements, whether written, oral, or via electronic communication, or authorizing any action that could reasonably be anticipated to cause damage to or reflect negatively upon Executive’s reputation except in response to any statements made by Executive or his representative in violation of the terms of this paragraph. This paragraph does not apply to truthful testimony compelled by applicable law or legal process.

d. Intellectual Property. Nothing contained in this Agreement shall be deemed to limit or restrict any rights which the Company or any of its affiliated or related entities may have as a matter of law or otherwise to any inventions, copyrightable material, trade secrets or other work conceived, developed, created or otherwise performed by Executive during the course of his employment or relating in any way to his work for the Company. Executive agrees to cooperate with the Company to further document its ownership of such property.

e. Return of Company Property. Within seven days of the Termination Date, Executive shall return to the Company all work product, documents relating to Inventions, and Confidential Information, and all other property of the Company, including, without limitation, all computers, telephones, personal digital assistants, and other equipment, proprietary or licensed computer programs, customer lists, customer data, books, records, forms, specifications, formulas, data, data processes, designs, papers, and writings relating to the business of the Company, and all copies thereof, in his possession or under his control, with the exception of information Executive is entitled to retain under paragraph 7.7 of the Employment Agreement.

a. Breach/Remedy. Executive and the Company acknowledge that nothing in this Agreement in any way limits the legal rights they may have to pursue any claim relating to breach of this Agreement. The parties recognize that a breach by the Executive of any of the covenants herein contained would result in damages to the Company and that the Company could not adequately be compensated for such damages by monetary award. Accordingly, the Executive agrees that in the event of any such breach, in additional to all other remedies available to the Company at law or in equity, the Company shall be entitled as a matter of right to apply to a court of competent jurisdiction for such relief by way of restraining order, injunction, decree or otherwise, as may be appropriate to ensure compliance with the provisions of this Agreement.

b. No Admission of Liability. Executive specifically understands and agrees that by entering into this Agreement, the Company and the other Released Parties do not admit any liability whatsoever to him or to any other person arising out of any claims or causes of action heretofore or hereafter asserted by him, and the Company, for itself and on behalf of its affiliates and related entities, expressly denies any and all such liability.

7

c. Indemnification. Notwithstanding this Agreement, Executive’s rights to indemnification, if any, are and continue to be governed by the Company’s Articles of Incorporation, Bylaws, and applicable law, and Section 6 of the Employment Agreement, subject to any qualifications, limitations or conditions expressed therein. Nothing contained in this Agreement shall be deemed to constitute a waiver or release by Executive of any indemnification rights existing as of the date hereof arising out of his status as a former employee or officer of the Company or any of its affiliated or related entities.

d. Section 409A. This Agreement is intended to comply with Section 409A of the Internal Revenue Code, to the extent applicable. Notwithstanding any provision herein to the contrary, the Agreement shall be interpreted and administered consistent with that intent. If this Agreement provides for multiple payments, each separate payment provided pursuant to the terms of this Agreement shall be treated as a separate “payment” for the purposes of Section 409A. In addition, Executive understands that if he is determined by the Company to be a “specified employee” within the meaning of Section 409A, certain payments made in connection with the termination of his employment will not be made earlier than six months after the date of such termination, if so required by Section 409A.

e. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the Province of British Columbia and the laws of Canada applicable therein, without giving effect to principles of conflict of laws.

f. Dispute Resolution. Any dispute arising out of or relating to the application or interpretation of this Agreement shall be submitted to final and binding arbitration in accordance with the provisions of the B.C. Commercial Arbitration Act, except for any dispute relating to Executive’s continuing obligations referenced in paragraph 8 of this Agreement when injunctive relief may be reasonably required.

g. Counterparts. This Agreement may be executed in counterparts and such counterparts may be exchanged in PDF format.

h. Interpretation. (i) Any rule of interpretation that any ambiguity is to be resolved against the drafting party is not applicable to this Agreement. (ii) All headings in this Agreement have been inserted solely for convenience of reference only, are not to be considered a part of this Agreement and shall not affect the interpretation of any of the provisions of this Agreement. (iii) In this Agreement, the singular shall include the plural, and the masculine shall include the feminine gender, unless the context otherwise requires. (iv) Capitalized terms used herein shall have the meaning ascribed to them in the Employment Agreement, except that “Company” shall include, as the context may require, CHC Helicopter S.A. and any of its affiliated or related entities.

i. Entire Agreement. This document contains the entire agreement between the parties with respect to the ending of Executive’s employment, and cancels and supersedes all prior agreements and discussions between them relating to the ending of Executive’s employment.

8

j. Variation. No amendment or variation of the terms of the Agreement will be effective or binding unless in writing and signed by both parties.

12. Severability and Waiver. Each provision of this Agreement is a separate obligation and is severable from all other such obligations, and if any of them is held by a court to be invalid, this Agreement shall be construed by limiting, restricting or reducing the application of the applicable provision or provisions, to the extent necessary to comply with applicable law then in effect.

No waiver of any provision of this Agreement shall be binding unless in writing and signed by both parties. No failure to exercise or delay in exercising any right or remedy under this Agreement shall be deemed to be a waiver of that right or remedy. No waiver or excuse by a party of any default or breach by the other party of any provision of this Agreement shall operate as a waiver of that party’s rights in respect of any continuing or subsequent default or breach, or affect the rights of that party in respect of any such continuing or subsequent default or breach.
