18.		Healthcare Benefits. You and your family will be covered under ev3’s expatriate healthcare coverage through the Blue Cross Blue Shield network throughout your assignment.
19.		Tax Equalization. It is the Company’s intent that differences in income tax expense due to a foreign assignment should not result in a significant advantage or disadvantage to you. Through tax equalization your total tax burden will approximate that of an ev3 employee working in his home country with the same marital and family status and comparable ev3 compensation, other income, and deductions. Instead of paying actual withholdings to the home country tax authorities, ev3 will withhold hypothetical taxes from your salary to use against your final hypothetical tax liability. As a global assignee, the hypothetical tax withholding will be determined

		with the assistance of Global Tax Network (GTN). All ev3 paid income, including incentive and stock option income, will be subject to this hypothetical tax withholding. If your personal financial circumstances require an alteration in the hypothetical tax withholding amount, you should discuss this with GTN. If GTN deems an alteration is warranted, they will notify ev3 and your withholding amount will be changed. Once you are on assignment, all tax withholding will typically take the form of this hypothetical tax withholding. ev3 may make actual national tax payments in the form of withholding on your behalf to avoid underpayment penalties. Such payments will be accounted for on the annual tax equalization calculation. This transaction will have no tax impact on you. GTN will contact you to arrange a pre-assignment discussion of your tax treatment.
20.		Tax Preparation Expenses. ev3 will pay for tax preparation services for your home and host country tax returns for the relevant tax years of your assignment, prepared by ev3’s tax advisor, GTN. GTN will assist you in filing any forms necessary in order to take full advantage of favorable tax treatment available during your assignment. It is your responsibility to provide all relevant information on a timely basis, to adhere to all applicable tax regulations, and to file appropriate tax returns in a timely manner. As per tax equalization policy, to the extent any of these amounts are taxable to you, ev3 will pay all taxes owed on such amounts.
21.		Employee Confidentiality Agreement. This Agreement supplements, but does not amend or modify, the Employee Confidentiality Agreement between you and ev3 dated October 24, 2000, which continues in full force and effect following the execution of this Agreement.
22.		Assignability. The rights and obligations contained herein shall be binding on and issue to the benefit of the successors and assigns of ev3. You may not assign your rights and obligations without the express written consent of Company.

23.		At-Will Employment. Notwithstanding anything contained herein, you acknowledge and agree that your employment status is that of an employee at-will, and your employment may be terminated by you or ev3 at any time, with or without cause. Nothing in this Agreement shall be construed to create a contract of employment for any definite or guaranteed length of time.
24.		Entire Agreement: This letter constitutes the entire Agreement between you and ev3 with respect to the subject matter hereof and supersedes all previous agreements and understandings whether oral or written between the parties with respect to the subject matter hereof. This Agreement may be executed in separate counterparts, and by facsimile, each of which will be deemed an original, and when executed separately or together, will constitute a single original instrument, effective in the same manner as if the parties had executed one and the same instrument. This Agreement may only be modified in a writing signed by both of the parties hereto.
