11.    Termination:

11.01    You may resign your employment voluntarily upon giving thirty (30) days prior written notice to Cognos. Cognos may waive the said notice by providing you with pay in lieu of notice. Upon resignation, you will have no entitlement to compensation except for unpaid Base Salary and vacation earned to the effective date of resignation.

(a)    Cognos will continue to pay your monthly Base Salary and monthly payments equal to one twelfth (1/12) of your base target bonus (without applying any applicable adjustments for the overall corporate performance of Cognos Incorporated such as pursuant to the “Share In Success Program” of Cognos Incorporated in effect as of the Effective Date or any replacement program), in each case less statutory deductions, for eighteen (18) months from the date of termination. Cognos may elect to pay this as a single lump sum payment;

(b)    Cognos will continue, to the extent permitted by its carriers, all benefits for eighteen (18) months from the date of termination. In the event that Cognos cannot continue to provide any benefit, it shall compensate you for the reasonable cost of your obtaining the said benefit to the extent you can obtain such benefit from a similar carrier;

(c)    You shall be entitled to be paid your target bonus as at the date of termination (together with any applicable adjustments for the overall corporate performance of Cognos Incorporated such as pursuant to the “Share in Success Program” of Cognos Incorporated in effect as of the Effective Date or any replacement program), pro-rated for the period up to the date of termination of employment (such payment to be determined and made at the times that Cognos generally determines and pays bonuses to its Senior Executives); and

(d)    Notwithstanding the terms of any plan or agreement to the contrary, all of your entitlements or rights pursuant to any share option plan shall continue to vest during the eighteen (18) month period following the date of termination, and once vested shall be exercisable in accordance with the terms of the applicable plan.

11.04    In the event that your employment is terminated by Cognos without Just Cause or in the event that you terminate your employment for Good Reason and if such termination by Cognos or by you occurs on or within twelve (12) months following the date of any Change of Control, then, notwithstanding the terms of any plan or agreement to the contrary, all of your entitlements or rights pursuant to equity-based plans (including, without limit, share/stock option, share/stock purchase, restricted stock or stock award), or any profit sharing, bonus or incentive plan restricted stock plan shall automatically become fully vested, and once vested shall be exercisable in accordance with the terms of the applicable plan.

166

11.05    The terms “Good Reason”, “Just Cause” and “Change of Control” will have the meanings ascribed thereto in Schedule 1 of this Agreement.

11.06    Coincident with, or immediately following termination of your employment, for whatever reason, you will surrender to Cognos any documents or electronic media containing Confidential Information referred to in Section 9, as well as any other property of Cognos in your control or possession (including without limitation: vehicles, access passes, equipment, credit cards, keys, books, records, reports, files, manuals, and literature) in good condition, normal wear and tear excepted.

11.08    Immediately following termination of your employment, for whatever reason, you will repay any outstanding debts or advances owing by you to Cognos and you authorize Cognos to deduct the amount of those debts or advances from any compensation amount payable to you following your termination. For greater certainty, any unearned vacation taken will constitute an advance owed by you to Cognos and any incentive payment, signing bonus or payment of relocation and/or immigration expenses which becomes repayable due to termination of employment, shall constitute a debt owed by you to Cognos.

11.09    You will not at any time after termination of your employment represent yourself as being in any way connected or interested in the business of Cognos or any of its group companies worldwide.

13.    Non-Competition:    You will not, during your employment and for the period ending twelve (12) months after the date your employment is terminated, directly or indirectly or in any manner whatsoever, including either individually, or in partnership, jointly or in conjunction with any other person, or as principal, agent, owner, consultant, contractor, employee, executive, officer, director, advisor or shareholder: (a) be engaged in any undertaking, or (b) have any financial or other interest (including an interest by way of royalty or compensation arrangements) in or in respect of the business of any person which carries on a business; or (c) accept employment with, advise, render or provide services to, lend money to or guarantee the debts or obligations of any
