IV. REPATRIATION

Repatriation

Other than in cases of involuntary termination (with cause), and voluntary resignation, you are guaranteed a right of return to your home location at the end of the international secondment. Failure to return to Switzerland at the end of your secondment will be deemed a voluntary resignation. Subject to your satisfactory performance while on secondment and the Company’s business needs, 3D Systems will take reasonable efforts to return you to a position at least equivalent to the position held prior to your secondment.

Separation Without Cause

Your secondment is scheduled to last for two (2) years. Should your employment with the Company be terminated involuntarily during this secondment without cause, 3D Systems will pay to transport you and your family and household goods back to Switzerland provided you return to Switzerland within 30 days of termination. Termination will require immediate settlement of outstanding tax, travel and other advances.

If you are terminated without cause prior to January 13, 2020, 3D Systems shall pay you a severance payment in a lump sum equal to 12 months’ base salary calculated on the applicable rates payable pursuant to your employment contract with the Company (not a grossed up secondment rate). You will be eligible for any US-based benefits continuation under COBRA for a 12-month period.

Resignation

In the event that you voluntarily resign for any reason during the secondment, you are responsible for the cost of all transportation for you and your dependent family members and personal effects from your secondment location to your home country. Cash equivalent payments for these expenses will not be made, nor will you be entitled to any relocation allowance or further housing or other allowances from 3D Systems.

Code of Conduct

You should understand that you can be, and often are, highly visible representatives of 3D Systems Inc. in the host location. As such, you will need to be familiar with and adhere to the Company policies and applicable home and host country work laws. It is imperative that you and your family members follow both the letter and the spirit of the law, not only to protect yourselves from criminal or civil penalties, but also to maintain and advance the Company’s image as a reputable corporate citizen in the countries in which we operate. You will be expected to operate in compliance with the Company’s Code of Conduct at all times.

By signing below, you agree that your employment relationship and all terms and conditions of your employment relationship shall be governed exclusively by and construed in accordance with U.S. law, and that any action, claim, cause of action, charge, or complaint relating to or arising out of your employment or your separation from employment shall be brought for resolution in U.S. Federal Court.

Please let me know if you have questions.

Sincerely,

/s/ Andrew M. Johnson, EVP, CLO & Secretary, 3D Systems Corporation / March 7, 2018
