Dear Kevin:



We are pleased to inform you that, pursuant to the Entrust Technologies, Inc. Change in Control Bonus Incentive Plan (the Plan),

bonus payable to you upon a Change in Control is dependent upon the Fair Market Value of the Common Stock on such date and is reflected in the chart below.



This Award is subject to the applicable terms and conditions of the Plan, which are incorporated herein by reference, and in the event of any contradiction, distinction
or difference between this letter and the terms of the Plan, the terms of the Plan will control. Unless otherwise stated, all capitalized terms used herein have the meanings set forth in the Plan.



You will be entitled to receive a cash bonus (payable under the terms of the Plan) based on
the Fair Market Value of Common Stock on the date that a Change in Control occurs (a Common Stock Price Target), as follows:
